Self-Billing Invoices (UK): What Freelancers Should Check Before Signing a Self-Billing Agreement

A publisher emails: "We operate self-billing for all our contributors. Please sign the attached self-billing agreement and return it before we can process your first payment. Do not send us invoices."

You read the agreement. It says the publisher will create your invoices, you will not issue your own, and you agree to accept the invoices they send you. You are not sure what this means for your records, your VAT return, or whether you should sign it.

Self-billing is an arrangement where your client (the customer) creates your invoice instead of you sending one. The client prepares the invoice showing what you supplied, the amount, and the VAT (if you are both VAT registered), then sends you a copy with payment. You do not send your own sales invoice for those supplies.

This guide explains what self-billing is and who uses it (publishers, agencies, platforms, courier networks, big corporate clients), covers the difference between VAT-registered and non-VAT-registered freelancers (HMRC VAT self-billing rules apply only when both are VAT registered), walks through what a valid self-billing agreement must contain (your agreement to accept their invoices, not to issue your own, expiry date, commitment to notify VAT changes), shows what must appear on each self-billed invoice you receive (full VAT invoice details plus your name, address, VAT number, and the statement 'The VAT shown is your output tax due to HMRC'), explains the traps for freelancers (the VAT is YOUR output tax not input tax, you may owe it before payment arrives, check the rate, never treat it as a purchase, tell the client when you register for VAT, do not also send your own invoice), provides a worked £ example with an invented client (monthly self-billed invoices for a copywriter, one mistake caught and corrected), includes copy-paste email templates to accept, to ask for changes, and to query errors, offers a before-you-sign checklist and an each-month checklist, explains where SoloPad fits (recording self-billed invoices against clients, tracking payment status), and finishes with FAQ, sources, and related guides.

What self-billing is (and who uses it)

Self-billing is a commercial arrangement between you (the supplier) and your client (the customer). Instead of you sending an invoice to the client, the client creates the invoice and sends a copy to you with payment.

How it works:

1. You do the work (write articles, deliver packages, design graphics, code software)
2. Your client prepares an invoice on your behalf showing what you supplied and the amount
3. The client sends you a copy of the invoice with payment
4. You record the invoice as a sale in your books and account for the VAT (if applicable)

You do NOT send your own invoice for supplies covered by the self-billing agreement.

Who uses self-billing

Self-billing is common in industries where one party (the customer) handles high volumes of small suppliers or needs to control invoicing timing for their own accounting.

Examples:

✓ Publishers and media companies — Self-bill freelance writers, photographers, and illustrators for articles, images, and commissioned work
✓ Delivery networks and courier firms — Self-bill drivers and couriers for completed deliveries
✓ Marketing agencies and design studios — Self-bill freelance designers, copywriters, and contractors for project work
✓ Platforms and marketplaces — Self-bill sellers or service providers for sales made through the platform
✓ Large corporate clients — Self-bill contractors and consultants to streamline accounts payable processes
✓ Construction and labour hire firms — Self-bill subcontractors for completed work

If your client handles hundreds of suppliers and pays in bulk monthly, self-billing makes their accounting easier. It also gives them control over invoice timing and format.

VAT-registered vs non-VAT-registered freelancers

HMRC's VAT self-billing rules apply only when both you and your client are VAT registered.

If you are VAT registered and your client is VAT registered:
The client includes VAT on the self-billed invoice. The invoice must follow HMRC's VAT invoice rules. You account for the VAT as your output tax (sales tax you owe to HMRC).

If you are NOT VAT registered (but your client is):
The client can still self-bill you, but they will not add VAT to the invoice. The arrangement is not a VAT self-billing arrangement under HMRC regulations, and the VAT-specific rules (agreement requirements, VAT invoice format, output tax accounting) do not apply. It is simply an arrangement where the client creates your non-VAT invoice.

If neither of you is VAT registered:
Self-billing is allowed, but again, HMRC's VAT self-billing regulations do not apply. The client issues a non-VAT invoice on your behalf.

This guide focuses on VAT-registered freelancers receiving VAT self-billed invoices, as this is where the traps and HMRC rules apply. If you are not VAT registered, self-billing is simpler: the client sends you a non-VAT invoice, you check the amount matches your records, and you record it as a sale.

What a valid self-billing agreement must contain

You can only accept self-billed invoices if you have signed a formal self-billing agreement with your client. HMRC requires the agreement to include specific terms.

HMRC's required terms (VAT Notice 700/62, section 3.1):

A valid self-billing agreement must include:

✓ Your agreement that the client can issue invoices on your behalf — You agree they will create your sales invoices for the supplies you make to them
✓ Your agreement not to issue your own VAT invoices for those supplies — You will not send your own sales invoices for work covered by the agreement (doing so creates double-counting and breaks the arrangement)
✓ Your agreement to accept the self-billed invoices the client sends you — You agree the invoices they create are valid sales invoices for your records
✓ An expiry date or review date — Usually 12 months from the start date, or the end date of any business contract you have with the client
✓ Your agreement to notify the client immediately if:

• Your VAT registration number changes
• You cancel your VAT registration (deregister)
• You transfer your business as a going concern
  ✓ Details of any third party handling the billing — If the client outsources the invoicing to an accounting bureau or software provider, the agreement must state this

The agreement must be in writing (paper or electronic) and both you and the client must sign it or confirm acceptance.

You must keep a copy of the agreement and be able to show it to HMRC if they ask.

What the agreement looks like

HMRC provides an example self-billing agreement template in VAT Notice 700/62, section 8 (available as a PDF on GOV.UK). Your client's agreement should look similar.

Typical structure:

SELF-BILLING AGREEMENT

Between:
[Client company name, address, VAT number] (the Customer)

And:
[Your business name, address, VAT number] (the Supplier)

1. The Supplier agrees that the Customer may issue VAT invoices on the Supplier's behalf for supplies made by the Supplier to the Customer.

2. The Supplier agrees not to issue VAT invoices in respect of supplies covered by this agreement.

3. The Supplier agrees to accept all self-billed invoices issued by the Customer on the Supplier's behalf.

4. This agreement will run from [start date] to [expiry date, usually 12 months later], unless terminated earlier by either party giving written notice.

5. The Supplier agrees to notify the Customer immediately if:
   - The Supplier's VAT registration number changes
   - The Supplier deregisters for VAT
   - The Supplier transfers the business as a going concern

6. [If applicable] The Customer will use [third party name] to issue self-billed invoices on behalf of the Supplier.

Signed: _____________________  [Supplier]   Date: ___________
Signed: _____________________  [Customer]   Date: ___________

If the agreement your client sends you is missing any of the required terms, ask them to add them before you sign.

How long the agreement lasts

Self-billing agreements usually last 12 months, after which the client should review the agreement and ask you to renew it.

Why the review matters:
The review confirms you are still VAT registered, you still agree to the arrangement, and the terms are still valid. HMRC expects clients to review agreements regularly to prove the arrangement is consensual.

If the agreement is part of a longer business contract:
The self-billing agreement can last as long as the contract (for example, a two-year retainer contract can include a two-year self-billing agreement). The client does not need to review it separately until the contract ends.

If you supply the client for less than 12 months:
The client does not normally need to review the agreement.

Source: HMRC VAT Notice 700/62, sections 3.3.1–3.3.4

What must appear on each self-billed invoice you receive

Once you have signed a self-billing agreement, your client will send you self-billed invoices (usually monthly or per delivery/project). Each invoice must contain all the information HMRC requires for a full VAT invoice, plus your supplier details.

Required fields (HMRC VAT Notice 700/62, section 4.2):

✓ The words 'SELF-BILLING' — HMRC requires every self-billed invoice to be clearly marked as self-billing
✓ Your (the supplier's) name — Your business name or trading name
✓ Your address — Your business address
✓ Your VAT registration number — Your VAT number (the client cannot issue VAT invoices without this)
✓ The client's (customer's) name and address — Their business name and address
✓ The client's VAT registration number — Their VAT number
✓ A unique invoice number — Sequential and unique (the client's invoice numbering system)
✓ Invoice date — The date the client issued the invoice
✓ Tax point (date of supply) — The date you supplied the goods or services (this determines which VAT return the transaction goes on)
✓ Description of the goods or services — What you supplied (e.g. "Freelance copywriting services, October 2026")
✓ Quantity and price — How much you supplied and the rate (e.g. "10 articles @ £150 each")
✓ Net amount (before VAT) — The total before VAT
✓ VAT rate — The VAT rate applied (20% standard, 5% reduced, 0% zero-rated)
✓ VAT amount — The VAT charged
✓ Gross total — Net + VAT (what the client will pay you)
✓ The statement: 'The VAT shown is your output tax due to HMRC' — HMRC strongly recommends this statement to prevent you mistakenly treating the invoice as a purchase and reclaiming the VAT

Example self-billed invoice

Here is what a valid self-billed invoice looks like:

SELF-BILLING

Invoice number: SB-2026-1042
Invoice date: 31 October 2026
Tax point (date of supply): 31 October 2026

From (Customer):
Northline Publishing Ltd
28 High Street, London, EC1A 1BB
VAT number: GB 123 4567 89

To (Supplier):
Oak & Pixel (Freelance Copywriter)
14 Park Lane, Bristol, BS2 8QR
VAT number: GB 987 6543 21

Description:
Freelance copywriting services — October 2026
10 articles delivered (£150 per article)

Net amount:       £1,500.00
VAT @ 20%:          £300.00
Gross total:      £1,800.00

The VAT shown is your output tax due to HMRC.

Payment will be made by BACS on 15 November 2026.

What to check:

✓ The invoice is clearly marked 'SELF-BILLING'
✓ Your name, address, and VAT number are correct
✓ The net amount matches what you agreed or expected
✓ The VAT rate is correct (20% for most services)
✓ The description matches the work you did
✓ The tax point (date of supply) is accurate
✓ The statement about output tax is present (if not, ask the client to add it)

The traps for freelancers: what you must know about self-billed invoices

Self-billing creates specific VAT traps for suppliers. These are the mistakes freelancers make most often.

Trap 1: The VAT is YOUR output tax, not input tax

The mistake:
You receive a self-billed invoice showing £300 VAT. You think: "This is a purchase invoice from my client. I can reclaim the £300 VAT as input tax."

Wrong.
A self-billed invoice is a sales invoice. It represents a sale you made to the client. The VAT shown is your output tax (VAT you owe to HMRC on your sales), not input tax (VAT you can reclaim on purchases).

What you must do:
Record the self-billed invoice as a sale in your books. Declare the £300 VAT as output tax on your VAT return (box 1). Add the net amount (£1,500) to your sales (box 6).

Do NOT:
✗ Treat the self-billed invoice as a purchase invoice
✗ Reclaim the VAT as input tax (box 4)
✗ Add it to your purchases (box 7)

If you make this mistake, HMRC will assess you for the VAT you claimed incorrectly, plus interest and possibly a penalty.

Source: HMRC VAT Notice 700/62, section 6.4

Trap 2: You may owe the VAT before payment arrives

The timing trap:
The VAT on a self-billed invoice is due to HMRC based on the tax point (date of supply), not the payment date.

Example:
You deliver 10 articles on 31 October 2026 (the tax point). The client sends you a self-billed invoice dated 31 October showing £300 VAT. They pay you on 15 November 2026.

When you must account for the VAT:
You must declare the £300 output tax on the VAT return covering the period that includes 31 October (the tax point), even though you have not been paid yet.

If you are on quarterly VAT returns and the July–September 2026 period covers 31 October:
You declare the £300 in that return, due by 7 November 2026 (before the client pays you on 15 November).

Cash accounting scheme exception:
If you use the VAT cash accounting scheme, you account for VAT when you receive payment, not at the tax point. This avoids the timing trap.

Source: HMRC VAT Notice 700/62, sections 5.1, 5.2, and 6.5

Trap 3: Check the VAT rate the client used

The client's mistake:
Your client applies 20% VAT to a supply that should be zero-rated or reduced-rated.

Example:
You supply digital books (zero-rated for VAT). The client's accounting system applies 20% VAT and self-bills you £1,000 net + £200 VAT.

The problem:
The £200 VAT is wrong. You should not be charging VAT on zero-rated supplies. If you declare the £200 as output tax on your VAT return, you will overpay HMRC. If you do not declare it, your VAT return will not match the self-billed invoice, and HMRC may query it.

What you must do:
Contact the client immediately and ask them to issue a corrected self-billed invoice with the correct VAT treatment (£1,000 net, zero-rated, £0 VAT).

You are responsible for the VAT accuracy:
Even though the client creates the invoice, HMRC holds you (the supplier) accountable for the VAT on your supplies. Check every self-billed invoice to ensure the VAT rate is correct.

Source: GOV.UK VAT self-billing arrangements overview and HMRC VAT Notice 700/62, section 6.4

Trap 4: Tell the client when you register for VAT

What happens if you register for VAT after signing a non-VAT self-billing agreement:

You sign a self-billing agreement with a client when you are not VAT registered. The client self-bills you without VAT (e.g. £1,500 per month, no VAT).

Six months later, you register for VAT because your turnover crosses the £90,000 threshold.

You must tell the client immediately.

Why:
The client cannot issue VAT invoices on your behalf until you have set up a new self-billing agreement that includes your VAT number. If they continue self-billing you without VAT after you register, those invoices are not valid VAT invoices.

What you must do:

1. Notify the client the day you register for VAT
2. Provide your VAT number
3. Sign a new self-billing agreement that includes your VAT number
4. The client will then add 20% VAT to future self-billed invoices

If your VAT number changes:
You must also notify the client immediately. The client must prepare a new self-billing agreement with your new VAT number. They cannot issue VAT invoices under the old agreement with the old number.

Source: GOV.UK VAT self-billing arrangements and HMRC VAT Notice 700/62, sections 3.1 and 4.1

For more on when to register for VAT, see when to register for VAT UK freelancers.

Trap 5: Do not also send your own invoice

The double-counting trap:
You sign a self-billing agreement. The client self-bills you £1,800 for October's work. You forget about the agreement and also send your own invoice for £1,800 for the same work.

The problem:
Now there are two invoices for the same supply. If the client pays both, you have been overpaid. If you declare both as sales on your VAT return, you will overpay VAT and income tax.

What you must do:
Never issue your own sales invoice for supplies covered by a self-billing agreement.

If you accidentally send an invoice, cancel it immediately (mark it VOID) and notify the client: "Please ignore invoice INV-2026-042. This work is covered by our self-billing agreement. I will accept the self-billed invoice you send."

The exception:
If the self-billing agreement ends or you terminate it, you can start issuing your own invoices again for future supplies.

Source: HMRC VAT Notice 700/62, sections 3.1 and 6.3

Trap 6: Keep copies and match them to payments

The record-keeping trap:
Your client self-bills you monthly. The invoices arrive by email. You file them in a folder and forget about them. Six months later, you cannot remember which invoices were paid, which month each payment covered, or whether any are outstanding.

What you must do:
✓ Save every self-billed invoice (PDF or print) in your records
✓ Match each invoice to the payment when it arrives in your bank (use remittance advice if the client sends it, or match by payment reference and amount)
✓ Mark each invoice as paid in your invoice log once payment clears
✓ If a payment does not match a self-billed invoice, query it immediately

HMRC expects you to keep records of all self-billed invoices for at least 6 years (VAT-registered businesses) or 5 years after the 31 January Self Assessment deadline (sole traders).

For more on matching payments to invoices, see remittance advice UK.

Source: HMRC VAT record-keeping requirements and GOV.UK Self Assessment record-keeping rules

Trap 7: Your own invoice-number sequence

The numbering confusion:
You use sequential invoice numbers for your own invoices (INV-2026-001, INV-2026-002...). Your client self-bills you and uses their own invoice numbering (SB-2026-1042, SB-2026-1043...).

What you must do:
Keep both sequences separate. The self-billed invoices use the client's numbering system. Your own invoices (for other clients) use your numbering system.

In your records:
Record self-billed invoices under the client's invoice numbers (SB-2026-1042). Do not renumber them into your own sequence.

Example invoice log:

Mark self-billed invoices clearly so you do not confuse them with your own invoices.

For more on invoice numbering, see invoice number UK.

Worked example: a copywriter receiving monthly self-billed invoices

Here is a step-by-step example showing how a UK freelance copywriter handles self-billing from a publisher.

Scenario

Freelancer: Harper at Oak & Pixel (sole trader, VAT registered)
Client: Northline Publishing Ltd (VAT registered)
Work: Freelance copywriting, 10 articles per month @ £150 per article (£1,500 net, £300 VAT, £1,800 gross)
Arrangement: Northline operates self-billing for all contributors
Date: October 2026

Step 1: Harper receives a self-billing agreement

Northline emails Harper:

Subject: Self-billing agreement — Northline Publishing

Hi Harper,

We operate self-billing for all our freelance contributors. This means we will create and send you invoices for your work, and you will not need to send us invoices.

Please read the attached self-billing agreement and return it signed by 20 October.

Once the agreement is in place, we will send you a self-billed invoice on the last day of each month, and payment will follow within 14 days.

Let us know if you have any questions.

Best,
Northline Finance Team

Harper reads the agreement. It includes:

✓ Harper's agreement that Northline can issue invoices on Harper's behalf
✓ Harper's agreement not to issue sales invoices for work covered by the agreement
✓ Harper's agreement to accept the self-billed invoices
✓ Expiry date: 12 months from signing
✓ Harper's commitment to notify Northline if VAT status changes

Harper signs the agreement and returns it on 18 October.

Step 2: Harper delivers October's articles

Harper writes and delivers 10 articles during October 2026. Harper does not send an invoice to Northline (the self-billing agreement covers this).

Step 3: Harper receives the first self-billed invoice

On 31 October 2026, Northline emails Harper a self-billed invoice:

SELF-BILLING

Invoice number: SB-2026-1042
Invoice date: 31 October 2026
Tax point (date of supply): 31 October 2026

From (Customer):
Northline Publishing Ltd
28 High Street, London, EC1A 1BB
VAT number: GB 123 4567 89

To (Supplier):
Oak & Pixel (Harper, Freelance Copywriter)
14 Park Lane, Bristol, BS2 8QR
VAT number: GB 987 6543 21

Description:
Freelance copywriting services — October 2026
10 articles delivered (£150 per article)

Net amount:       £1,500.00
VAT @ 20%:          £300.00
Gross total:      £1,800.00

The VAT shown is your output tax due to HMRC.

Payment will be made by BACS on 15 November 2026.

Step 4: Harper checks the invoice

Harper checks the invoice line by line:

✓ Marked 'SELF-BILLING' — Correct
✓ Harper's name, address, and VAT number — Correct
✓ Net amount £1,500 (10 articles x £150) — Correct
✓ VAT rate 20% — Correct (standard-rated services)
✓ VAT amount £300 — Correct
✓ Gross total £1,800 — Correct
✓ Tax point 31 October — Correct (this is when Harper delivered the articles)
✓ Statement about output tax — Present

Everything looks correct. Harper saves the PDF in a folder: Self-Billed Invoices / Northline / SB-2026-1042.pdf.

Step 5: Harper records the invoice as a sale

Harper adds the invoice to the invoice log:

Harper also records the sale in the accounting software:

• Sales: £1,500 (box 6 on VAT return)
• Output tax: £300 (box 1 on VAT return)
• Tax point: 31 October 2026

Harper will declare this on the VAT return for the period covering October (July–September 2026 quarter if on quarterly returns, or October 2026 if on monthly returns).

Step 6: Payment arrives

On 15 November 2026, Harper checks the bank statement:

Date: 15 Nov 2026
Description: BACS payment — Northline Publishing — SB-2026-1042
Amount: £1,800.00

The payment matches the invoice gross total (£1,800). Harper updates the invoice log:

Step 7: November invoice arrives with a mistake

On 30 November, Harper receives the November self-billed invoice:

SELF-BILLING

Invoice number: SB-2026-1078
Invoice date: 30 November 2026
Tax point: 30 November 2026

Net amount:       £1,500.00
VAT @ 5%:            £75.00
Gross total:      £1,575.00

Harper spots the error: VAT rate is 5% instead of 20%.

Copywriting services are standard-rated (20% VAT), not reduced-rated (5%).

Step 8: Harper queries the error

Harper emails Northline immediately:

Subject: Query on self-billed invoice SB-2026-1078 — VAT rate incorrect

Hi Northline Finance Team,

Thank you for the self-billed invoice SB-2026-1078 for November's articles.

I notice the VAT rate is shown as 5%, but copywriting services are standard-rated at 20%. The correct VAT should be £300 (20% of £1,500), not £75.

Can you issue a corrected self-billed invoice with the correct VAT rate?

If you need any clarification on the VAT treatment, please let me know.

Thanks,
Harper
Oak & Pixel

Step 9: Northline corrects the invoice

Northline replies:

Hi Harper,

Apologies — this was a system error. We have cancelled invoice SB-2026-1078 and issued a corrected invoice: SB-2026-1078-R1.

The corrected invoice shows:

Net: £1,500.00
VAT @ 20%: £300.00
Gross: £1,800.00

Payment will follow on 15 December as usual.

Best,
Northline Finance Team

Harper saves the corrected invoice and records it in the log. Harper deletes (or marks as void) the incorrect invoice SB-2026-1078.

Summary

Total invoiced (October + November): £3,000 net, £600 VAT, £3,600 gross
Total received: £3,600 (£1,800 in November, £1,800 in December)
Output tax declared: £600 (£300 for October, £300 for November)

Lessons:

✓ Harper did not send any invoices (the self-billing agreement covered this)
✓ Harper checked every self-billed invoice and spotted the VAT rate error
✓ Harper recorded each invoice as a sale, not a purchase
✓ Harper declared the VAT as output tax on the VAT return
✓ Harper matched payments to invoices and kept clear records
✓ Harper queried errors politely and got them corrected before payment

Should you agree to self-billing? Decision test

Before you sign a self-billing agreement, weigh the pros and cons.

Pros (why self-billing can be good)

✓ Less admin for you — No need to create and send invoices each month
✓ Faster payment on volume work — Clients who self-bill often pay faster because invoicing is automated
✓ Fewer payment queries — The client controls invoice timing and format, so there are fewer disputes about invoice details
✓ Standard practice in some industries — If you want to work with certain publishers, platforms, or agencies, self-billing may be non-negotiable

Cons (why self-billing can be risky)

✗ Less control over invoice timing — The client decides when the invoice is dated and when the tax point is recorded
✗ Less control over description and rate — The client writes the invoice description and applies the VAT rate (you must check it is correct)
✗ Errors land on you — If the client applies the wrong VAT rate, you are still responsible to HMRC (you must spot and correct errors)
✗ More VAT risk — You may have to account for output tax before payment arrives (unless you use cash accounting)
✗ Client can change terms — The client controls the invoice format and may change it without warning (you must review every invoice)

Decision test

Sign the self-billing agreement if:

✓ The client is a reputable publisher, platform, agency, or corporate client with established self-billing processes
✓ You are comfortable checking every invoice carefully for VAT rate errors
✓ You keep clear records and can match self-billed invoices to payments
✓ Self-billing is standard practice in your industry and refusing it would cost you work
✓ You want to reduce your own invoicing admin

Do NOT sign (or ask for changes) if:

✗ The agreement is missing required terms (see checklist below)
✗ The client has a history of payment problems or poor communication
✗ You are not confident you can spot VAT errors
✗ You prefer to control your own invoicing timing and format
✗ The client refuses to include an expiry date or review clause

HMRC will not force you to accept self-billing. You can refuse. However, some clients may make it a condition of doing business with you.

✓ Ask for a corrected self-billed invoice
✓ Do not declare the incorrect VAT amount on your VAT return until you receive the correction
✓ Keep a copy of the incorrect invoice marked as VOID

When payment arrives:

✓ Check the amount matches the gross total on the invoice
✓ If the amount does not match, query it immediately (see remittance advice UK for guidance)
✓ Mark the invoice as paid in your invoice log

VAT return:

✓ Declare the VAT on the self-billed invoice as output tax (box 1)
✓ Add the net amount to your sales (box 6)

This is a short optional mention — you do not need invoicing software to track self-billed invoices. A spreadsheet and a folder of PDFs work fine.

FAQ

Can I refuse a self-billing arrangement?

Yes. HMRC will not force you to accept self-billing. However, some clients (especially publishers, platforms, and large corporate clients) make self-billing a condition of working with them. You can refuse, but you may lose the work.

What happens if I send my own invoice by mistake after signing a self-billing agreement?

Cancel your invoice immediately (mark it VOID) and notify the client: "Please ignore invoice [number]. This work is covered by our self-billing agreement." Do not declare the voided invoice on your VAT return. Accept the self-billed invoice the client sends instead.

Do I include self-billed invoices in my invoice numbering sequence?

No. Self-billed invoices use the client's invoice numbering system (e.g. SB-2026-1042). Your own invoices (for other clients) use your own numbering system (e.g. INV-2026-078). Keep them separate in your records. Mark self-billed invoices clearly in your invoice log.

What if the client stops paying but continues to send self-billed invoices?

Stop working for the client. The self-billed invoices are still valid sales invoices, and you are still responsible for declaring the output tax. If you do work and the client self-bills you but never pays, you owe HMRC the VAT (unless you use cash accounting or can prove bad debt relief applies). Chase the unpaid invoices using the same process as any late invoice. See how to chase a late invoice.

Can I have self-billing agreements with multiple clients?

Yes. You can have separate self-billing agreements with multiple clients. Keep a copy of each agreement and track self-billed invoices separately by client.

What if I disagree with the amount the client self-bills me?

Query it immediately. Email the client: "The self-billed invoice shows £[amount], but we agreed £[different amount] for this work. Please issue a corrected invoice." Do not accept payment or declare the incorrect amount on your VAT return until the invoice is corrected.

Can the client self-bill me for work I have not done yet?

No. The invoice must reflect actual supplies you have made. The tax point is the date you provided the goods or services. If the client self-bills you before you have delivered the work, query it. The invoice date and tax point should match or follow the delivery date.

What happens if the self-billing agreement expires and we forget to renew it?

The client should stop issuing self-billed invoices. If they continue self-billing you without a valid agreement, the invoices are not valid VAT invoices. HMRC may disallow the VAT treatment. Renew the agreement immediately or start issuing your own invoices for new supplies.

Do self-billed invoices count as proof of income for a mortgage or loan application?

Yes. Self-billed invoices are sales invoices showing your business income. Keep copies of all self-billed invoices and bank statements showing payments received. Lenders will accept them as proof of income.

Can a client based outside the UK self-bill me?

Yes, but different VAT rules may apply depending on where the client is based and what you are supplying. If the client is in the EU or another country, check the place of supply rules and reverse charge arrangements. Self-billing agreements with non-UK clients must meet both UK and the client's country VAT requirements. Speak to an accountant if you are unsure.
