If you are self-employed in the UK, your strongest proof of income is your SA302 tax calculation, paired with its Tax Year Overview, both available from HMRC. Landlords often accept a tax return, an accountant's reference or recent bank statements instead. Which one you need depends on who is asking and how long you have been trading. This guide covers each document, where to get it, what lenders and letting agents ask for, and how to keep your records ready.
TL;DR
- For mortgages and loans, lenders usually want your SA302 and Tax Year Overview, often for the last two years.
- For renting, a tax return, an accountant's reference or three months of bank statements is commonly accepted. Rules differ by agent.
- You can download an SA302 from your HMRC online account. Software users may need to print it from their software.
- With no payslips, you are not without proof. Invoices, bank statements and tax records all count when they are organised.
- Keep every income record in one place, and for at least 5 years after the filing deadline.

What counts as proof of income if you are self-employed
Employees hand over payslips. You do not have them, so the evidence comes from HMRC, your accountant or your own records. Experian lists self-assessment tax returns, profit and loss statements and bank statements among the documents used in the UK to confirm income. Which ones carry weight depends on the request:
| Document | What it shows | Typically used for |
|---|---|---|
| SA302 tax calculation | Your income, deductions and tax due for a tax year | Mortgages, loans, some tenancies |
| Tax Year Overview | Whether that tax was paid or is recorded as due | Mortgages, loans |
| Self Assessment return (SA100) | The full return you submitted | Tenancies, some lenders |
| Accountant's certificate or reference | Your profit, confirmed by a qualified accountant | Mortgages, tenancies |
| Bank statements | Money actually received, usually 3 months or more | Tenancies, some loans |
| Invoices and contracts | Work done and expected payments | Supporting evidence, newer businesses |
The general rule: the closer a document is to an official HMRC record, the more weight a lender gives it. A figure you typed yourself carries little weight.
The SA302 and Tax Year Overview explained
The SA302 is HMRC's summary of your tax calculation. It shows your total taxable income for the tax year (6 April to 5 April), your sources of income, allowable deductions and reliefs, and the Income Tax and Class 4 National Insurance due. It is not the full tax return, which is the SA100.
The Tax Year Overview is its partner. It shows whether the tax on the SA302 was paid or is recorded as due. Lenders cross-check the two, and forgetting the overview is described as a common reason applications are sent back for missing documents.
How to download them
- Sign in to your HMRC online account (Personal Tax Account).
- Select Self Assessment.
- Choose the tax year and follow the link to get your SA302 tax calculation.
- Download the Tax Year Overview for the same year.
Allow 72 hours after submitting a return before you try to download or print these. Do this early, not on the day a lender asks.
If you file through software
If you file through commercial software such as FreeAgent, Xero, QuickBooks, TaxCalc or Sage, HMRC may not generate an SA302 in your account. You print the tax calculation from the software instead. The Tax Year Overview is still downloaded separately from HMRC.
If you cannot download either document, your accountant can usually produce a calculation from HMRC-recognised software. Some lenders accept this and others prefer documents taken directly from HMRC, so check with the lender first.
Proof of income for a mortgage or loan
Mortgage lenders ask for the most documentation, and they publish their requirements. The pattern is consistent: two years of figures, from HMRC.
- Two years of tax records. HSBC UK asks sole traders and most partnerships for the last two years of tax year overviews and tax calculations, with the most recent year dated within the last 18 months.
- Time trading. Nationwide requires self-employed applicants to have been self-employed in the UK for at least two years, with the latest two years of tax calculations accompanied by a Tax Year Overview.
- Company directors. If you run a limited company, the documents differ. Virgin Money states that directors with a 20% or greater shareholding cannot use SA302s alone. They need two years of full accounts and an accountant's covering letter.
- Only one year of figures. Some lenders will look at it. Aldermore may consider up to 90% loan to value with extra evidence, such as a previous employer reference, evidence of guaranteed income or accounts for the first six months of the current financial year.
Lenders differ, so read your chosen lender's own page before you apply. Do not adjust any figure to look better. The SA302 is HMRC's record of what you reported, and inflating income to borrow more is a form of mortgage fraud. If your situation is complicated, a mortgage adviser or a qualified accountant can tell you which lender suits your circumstances.
Proof of income without a payslip
A lender or landlord who asks for a payslip is usually asking for evidence of regular income. You can offer an equivalent. Nationwide says self-employed people, partners and company directors can use their last 12 months' tax calculations (SA302s) or tax year overviews dated within the last 12 months. A completed accountant's certificate signed by their accountant is also accepted.
Some income types are treated differently. The same Nationwide page lists income it does not accept as proof, including income from zero hours contracts, commission, bonus or overtime payments, and non-sterling income. If your earnings are mixed, ask the lender how they treat each stream before you apply.
Gig workers and platform income
If you earn through delivery, driving, freelance or marketplace platforms, you are generally treated as self-employed for tax. The documents above apply to you in the same way. In the meantime, the evidence is the platform's earnings statements, matching bank statements and your Self Assessment records. Keep all three together. Where a letting agent wants invoices, Goodlord's checklist says self-employed sub-contractors should provide three months of recent invoices or payslips with a contract.
Proof of income for a rental application
Letting agents set the bar by rent, not by a mortgage-style test. Most compare your income with a multiple of the rent, then ask for evidence.
- Tax return or SA302. Goodlord's criteria accept the most recent submitted return (SA100 or SA800) or an SA302. The return must show it was submitted, and the tax year must be the latest one filed.
- Accountant's reference. The same page accepts a reference from an accountant working for a professional accountancy business, using a professional email and landline.
- Bank statements. AB Lettings asks for either three months of bank statements showing income above three times the monthly rent, or the previous year's tax return showing that level.
- Longer history. HomeLet says self-employed tenants may need to show earnings over one to three years, and the agent may contact your accountant.
If you have been trading less than a year
Newer businesses are the hardest case. Goodlord's criteria say that income cannot be assessed if you have been self-employed for less than six months, although projected income from an accountant with a professional email address can be considered. Where there is no regular provable income, Belvoir accepts a recent bank or savings statement showing savings of more than 30 times the monthly rent. A guarantor is the other common route, so ask the agent early.
How to keep income records in order
Most rejected or delayed applications come down to missing paperwork, not low income. Self-employed people with several clients or platforms feel this most, because the records are scattered across emails, apps and bank accounts.
The legal minimum is clear. GOV.UK says you must keep business records for at least five years after the 31 January submission deadline of the relevant tax year. That is also a sensible window for the documents lenders ask for.
A workable system:
- One folder per tax year. Run it from 6 April to 5 April, matching your SA302.
- Download tax documents as soon as you file. Save the SA302, Tax Year Overview and a copy of the return together.
- Save platform and client statements monthly. Do not rely on being able to download them later, especially if you stop working with a client.
- Match income to bank deposits. A short note on which deposit belongs to which invoice saves questions later.
- Keep contracts and offer letters. They support income if your history is short.
- Name files consistently. Use the pattern year-month-source so you can find them fast.
If you also have employed work alongside your own trading, keep those payslips in the same place. Many people have a part-time job and freelance income, and lenders will want to see both.
Our perspective
Self-employed people are often told what to hand over, but rarely how to have it ready. The documents themselves are not difficult. The difficulty is finding them across different clients, agencies, employers and tax years, usually when a deadline is close.
That is the problem we built MyPay to solve. It gives you a secure, personal workspace where you can upload, organise and retrieve payslips and employment records, kept separate from any employer's access. If you move between jobs, agencies or a mix of employment and freelance work, your records stay in one place instead of in old inboxes.
Our side-by-side comparison lets you see changes in earnings and tax deductions between payslips. Our budgeting tools help you plan around income that varies. We do not replace HMRC documents such as the SA302, which remain the official record. We help you keep everything around them organised and easy to find.

Keep your income records in one place
If you mix employment with freelance or agency work, MyPay lets you upload and organise your payslips in a personal workspace, compare them side by side and see how your pay and deductions change over time. When a lender, landlord or accountant asks for evidence, your payslips are ready to retrieve.
If you invoice clients as a contractor, RivoFlow for invoicing and expenses helps you keep that side of your income tidy too. You can also use our take-home pay calculator to estimate what you keep after deductions when planning a budget.
FAQ
What is the best proof of income for a self-employed person in the UK?
For most lenders it is the SA302 tax calculation together with the Tax Year Overview, usually for the last two years. Both come from HMRC, which is why lenders trust them. For renting, a submitted tax return, accountant's reference or bank statements are often enough.
Can I prove my income without payslips?
Yes. Self-employed applicants can use SA302s or Tax Year Overviews, or an accountant's certificate, as Nationwide sets out. Bank statements, invoices and contracts can support these. If you also have employed work, keep those payslips too.
How long does it take to get an SA302?
You download it from your HMRC online account, but allow 72 hours after submitting your return. If you file through software, you may need to print the calculation from that software. Start early so you are not waiting on a deadline.
What if I have been self-employed for less than a year?
You have options, but fewer. Some lenders will consider one year of figures with extra evidence, and some letting agents accept bank statements, an accountant's projection, savings or a guarantor. Ask the lender or agent which they accept before applying.
