How to handle deposit payments UK (2026): CIS, VAT and crediting
Deposit payments UK, short answer: take a clear upfront deposit before (or as) work starts, put it on a proper invoice, and credit it later on stage or final bills. Who pays is the customer named on the quote. CIS may apply when a CIS contractor pays you for construction operations — soften with HMRC’s CIS overview and your accountant. A private householder paying for work on their own home is usually not CIS and is never treated as the CIS contractor for that home. If you are VAT-registered (threshold £90,000), show VAT correctly on taxable lines; if you are not registered, do not charge VAT.
This page is the how-to process for handling deposits (how much, when, how to credit). For the PDF field list and copy-paste deposit invoice shape, use the sister deposit invoice template UK. It is not a stage payment, progress / interim, or retention release. Figures below are illustrative only. Need the PDF now?

Who pays, CIS and VAT on a deposit
Start with who is paying the deposit and whether the work is construction operations. Deposit handling is about cash before work, not a CIS shortcut.
Who pays you | Typical deposit job | CIS? | VAT if registered |
|---|---|---|---|
Private householder | Domestic booking deposit on their own home | Usually no — never treat them as CIS contractor for own home | Often 20% on ordinary domestic works — soften Notice 708; do not invent 0% |
Main contractor / CIS contractor | Mobilisation / materials deposit on construction ops | May be in CIS base when ops are in scope — soften with HMRC / accountant | Normal VAT, or reverse charge only when eligible contractor tests met — never on a householder |
Developer / client | Contract deposit against a payment schedule | Depends whether the payer is a CIS contractor for construction ops | Show net / VAT / gross if registered |
Stage / progress (not this page) | Work completed to a named stage or % | Same CIS tests — use stage / progress sisters | Same VAT rules |
CIS rates (0% / 20% / 30%) sit with the contractor when CIS applies — InvoiceAdept does not decide status and does not file CIS300. VAT threshold is £90,000. InvoiceAdept does not file VAT returns, MTD updates or Self Assessment.
Deposit how-to vs deposit template vs stage vs retention
Use this page when you need the process for taking and crediting deposits. Sister pages stay for sister intents.
Page shape | When it fits | Cue |
|---|---|---|
Handle deposits (this page) | How much to ask, when to invoice, how to credit later | Process / policy + worked credit example |
Building the PDF field list | Must-have fields + copy-paste deposit invoice | |
Named contractual stage after work starts | Schedule stage label + amount | |
Open-ended % or valued progress | % complete / cumulative | |
Holdback previously deducted is now due | Release trigger + held amount |
If you only need the PDF shape, jump to the deposit template. If the money is a stage after work starts, use stage payment. Do not invent CIS on a householder deposit.
What a UK deposit invoice must include
Field | Always? | Deposit notes |
|---|---|---|
Your name or business name | Yes | Match Self Assessment / Companies House |
Your address and contact | Yes | Email helps customer queries |
Customer name and address | Yes | Ltd = registered name; add site address if different |
Unique sequential invoice number | Yes | e.g. INV-DEP-2026-0001 |
Invoice date | Yes | Date of issue |
Description of deposit | Yes | Site, % or fixed sum, what it covers; “deposit — credit on later stage / final” |
Quote / contract ref | Strongly recommended | Link deposit to the accepted quote |
Payment terms | Yes | Usually due on receipt before materials / start |
VAT number, rates, VAT amount | If VAT-registered | Show net, VAT and gross |
CIS UTR / deduction narrative | When a CIS contractor pays you within scope | Omit on true householder PDFs |
Bank details | Strongly recommended | Sort code and account name matching the invoice |
Never reverse-charge a private householder. Never invent CIS on a domestic own-home deposit.
Copy-paste deposit then credit example (illustrative)
Scenario: sole trader electrician takes a 30% deposit from a private householder for a consumer-unit upgrade. Not CIS. Not VAT-registered. Quote £2,000; deposit £600 (illustrative).
Line | Qty | Unit | Net |
|---|---|---|---|
Deposit 30% — consumer unit upgrade, 14 Oak Road, week commencing 14 Sep 2026 (credit on final) | 1 | Deposit | £600.00 |
CIS | Not applicable — private householder own home | ||
VAT | Not registered — net only | ||
Amount payable now | £600.00 | ||
Later final (illustrative) | Works £2,000 less deposit credit £600 = £1,400 |
Narrate on the PDF: “Deposit against quote [ref]. Will be credited on stage / final invoice. Not a retention. Householder — no CIS.” On the final, show a clear credit line so the customer sees the deposit was applied.
CIS, VAT and reverse charge cues
Topic | Practical rule |
|---|---|
Deposit for a CIS contractor on construction ops | May be in CIS base — soften |
Householder own-home deposit | Usually no CIS; never treat them as CIS contractor |
VAT threshold | £90,000 |
Domestic reverse charge | Never on a householder; contractor tests only |
Deemed contractor | £3 million construction-spend framing — not £1 million |
Deposit vs retention | Deposit is upfront; retention is holdback already earned |
InvoiceAdept | Does not file CIS300, VAT, MTD or Self Assessment |
How much deposit to ask for
Agree the deposit percentage or fixed sum in the quote before you start. Common shapes: 10–30% for domestic jobs, materials-only deposits when lead times are long, or a fixed mobilisation sum. Put refund / cancellation wording in writing if you use it — soften consumer-law points with your adviser where needed.
Shape | How to show it |
|---|---|
% of quote | “30% deposit on £X = £Y” |
Materials only | “Materials deposit £Y — labour billed on stage / final” |
Fixed mobilisation | “Mobilisation deposit £Y before start week” |
Deposit then stages | This process + deposit template first; stage sister for Stage 1+ |
Weak: “Deposit as agreed £600.” Usable: “30% deposit on quote Q-2026-0147 for 14 Oak Road = £600 net, not VAT-registered, householder — no CIS, credit on final.”
Payment terms and getting paid
Deposits are usually due on receipt before materials are ordered or the start date is locked. Put bank details on the PDF. On later stage or final invoices, show the deposit as a credit line so AP and householders can reconcile. Soften B2B late-payment interest with the contract and your accountant.
Common mistakes when handling deposits
Mistake | Fix |
|---|---|
Taking cash with no invoice | Issue a numbered deposit invoice every time |
Forgetting to credit the deposit later | Show a clear credit line on stage / final |
Calling a stage bill a deposit | Use stage / progress sisters once work is underway |
Calling a retention release a deposit | Use the retention sister for holdback release |
CIS narrative on a householder deposit | Remove CIS lines when the householder pays |
Charging VAT when not registered | Net only until registered |
Vague “deposit as agreed” | Name %, site, quote ref and credit intention |
Reverse-charging a householder | Never — reverse charge is contractor-to-contractor when tests met |
Frequently asked questions
Is a deposit the same as a stage payment?
No. A deposit is usually upfront before (or as) work starts. A stage payment bills a named schedule milestone once work is underway.
Does CIS always apply to deposits?
No. CIS may apply when a CIS contractor pays you for construction operations. Private householders on their own home are usually outside CIS — soften with HMRC / your accountant.
Can I put CIS deduction lines on a householder deposit?
Usually no. If a private householder pays the deposit on their own home, leave CIS narrative off the PDF.
What VAT threshold should I use in 2026?
£90,000. Soften registration with your accountant.
How is this different from the deposit invoice template?
That sister is the PDF field list and template. This page is the how-to process for taking and crediting deposits.
How is this different from retention?
Retention is holdback on sums already earned. A deposit is money taken before (or as) work starts.
Do I charge VAT on deposits if I am not VAT-registered?
No. Net only until you are registered.
Where can I build the PDF quickly?
Use the InvoiceAdept free invoice generator — Free covers 5 invoices; Pro is £7.99 and Pro+ £12.99 when you need more.
Next step: take the deposit properly
Agree the deposit in the quote, keep householder vs contractor facts straight, show CIS arithmetic only when due, and show VAT only if registered (£90,000 threshold). Open the free invoice generator, issue the deposit invoice, then credit it on stage or final. InvoiceAdept does not file CIS300, VAT returns, MTD or Self Assessment for you.
