Proving income as a self-employed driver — the documents lenders actually accept

A self-employed taxi or PHV driver does not have the one thing a lender's automated affordability engine is built around — a monthly payslip from a PAYE employer that lands in a bank account and matches a P60 at year end. Instead, income arrives in daily platform transfers, weekly cash takings, VAT-registered fares, and lumpy months around holidays and school terms. This guide explains what documents actually build a clean affordability picture, in what combination, and how to package them so an underwriter can approve the application quickly.

What lenders are really assessing

Under FCA CONC 5, a lender has a duty to run a proportionate affordability assessment on every regulated credit application. For a PAYE employee, the payslip and P60 do most of the work. For a self-employed driver, the lender is trying to answer three questions from documents: is this income real, is it stable enough to service the payment for the length of the agreement, and what are the outgoings? The document mix below is what actually answers those questions.

Definition

SA302

A summary of your self-assessment tax calculation issued by HMRC after your annual return is submitted.

The SA302 shows total income, tax due, and how it was calculated. It is the closest self-employed equivalent to a P60. Lenders use it as the anchor document — the number on the SA302 is what they credit as the applicant's declared income.

The three-document baseline

Bank statements — what the underwriter is scanning for

The underwriter reads bank statements far more forensically than most drivers realise. They are looking for the platform transfers you would expect (weekly settlements from Uber, Bolt), a steady pattern rather than a single big spike, evidence you separate business from personal spending, and — critically — the absence of unpicked gambling patterns, high-interest loan repayments, and unauthorised overdrafts. A tidy pattern for 3 months matters more than a peak month; consistency wins over headline number.

If you run a single account for business and personal, you are not disqualified — most sole-trader drivers do — but the underwriter has more work to do to separate the two flows. Providing a short explanatory note ('platform transfers total £X across the period; personal transfers £Y; net business income £Z') can save an underwriter an hour and get a decision back the same day rather than the next week.

SA302 — the anchor document

The SA302 is the number the lender will lean on hardest. It is HMRC-verified and hard to argue with. It shows the total income you declared for the last tax year and how the tax on it was calculated. Some lenders will accept a 'tax year overview' instead, which is a slightly shorter form covering the same ground. If your most recent SA302 is over 15 months old — i.e. you have not yet filed for the last full tax year — you can provide the most recent set plus year-to-date bookkeeping to bridge.

The one honest problem here is that drivers who declare very tight income to minimise tax may find their SA302 shows a number too low to support the finance they want. There is no clever way round this. The lender is required to lend on your declared income, not on what you say your real income is. If the SA302 is too low, either the vehicle needs to be cheaper, the deposit larger, or the term longer — or the affordability case cannot be built.

Platform summaries — Uber, Bolt, Free Now

Every major driver platform issues weekly and monthly earnings summaries in the driver app. These are useful for two reasons: they give the underwriter a granular picture of how the earnings are made up (fare income, tips, tolls, service fees deducted), and they cross-reference the bank statement transfers to prove the settlements are what they claim to be. A driver who works across two platforms should provide both — the totals combined into a single monthly income figure with a short note explaining the split.

Handling seasonality

Taxi and PHV income is not flat across the year. December is usually the biggest month; January and February the slowest. Airport-heavy drivers see peaks around school holidays; night drivers see weekly rhythms that do not match any Monday-to-Friday pattern. If your income has more than about 30% variance across the year, a lender will want to see 12 months rather than 3 or 6 — otherwise they cannot tell whether the 3 months you submitted are peak or trough.

The affordability figure a lender uses in that case is usually a rolling 12-month average rather than a spot 3-month projection. That is normally more favourable than a spot check taken in a slow month and less favourable than a spot check taken in December — either way, the 12-month view is what the underwriter will settle on.

Illustrative — how documentation completeness maps to approval outcomes

Numbers are illustrative and depend heavily on the driver's credit profile, deposit and licensing status. The point is that each layer of documentation adds real approval probability — the marginal return on tidying paperwork is high compared with almost anything else a driver can do at the application stage.

Cash-heavy drivers

Black-cab drivers in London and rank-based drivers in many towns still take a material portion of fares in cash. Cash is legitimate income but harder to evidence — it needs to appear on the bank statement as a deposit and on the SA302 as declared income. Drivers who bank their cash weekly and declare it in full are in a strong position; drivers who bank irregularly or under-declare will find lenders drop from the panel quickly. There is no lender who will lend on cash income that is not banked and declared.

What lenders will not accept

• Screenshots of a platform app as the only proof of income — must be an official statement or CSV export.
• Handwritten cash books instead of bank statements.
• A single peak-month bank statement — needs 3–6 months minimum.
• SA302 more than 18 months old with no year-to-date bookkeeping to bridge.
• Claimed income that materially exceeds the SA302 without a documented explanation.

The one-page cover note

A short cover note is the single cheapest thing a self-employed driver can do to improve approval odds. Half a page: your licensing authority and plate number, average weekly earnings across the last 12 weeks, monthly declared income from the most recent SA302, main platform(s) worked, deposit available, and any exceptional items (a slow month, a period out with the car in the shop). It replaces guesswork with facts and lets the underwriter make a decision, not an interpretation.

Where to go from here

If you are working out which vehicle to buy, our ULEZ / CAZ guide covers the licensing angle. If you have not yet arranged taxi-specific finance, the taxi-finance explainer walks through why a personal HP (A car finance product where you pay a fixed monthly amount and own the car outright at the end of the term.) will not do the job. The Taxi and PHV hub links to the named taxi adviser on our panel who can help package your documents before the application runs.
