Key Points
- The last full financial year is the basis of the assessment.
- An average of the last two years can be used if the latest year falls short.
- Profit is counted, not turnover.
- Cash savings cannot normally be combined with self-employed income.
How self-employment is treated
The figure that counts is your taxable profit for the year: income after allowable business expenses, as reported to HMRC. A strong recent few months does not help if the last completed year was below the threshold.
Relevant financial periods
You rely on the last full financial year, which for most sole traders runs from 6 April to 5 April. If that year was below the requirement, you can instead rely on the average of the last two full financial years.
Sole traders and partnerships
A sole trader counts their own profit. A partner in a partnership counts their share of the partnership profit. Both must still be trading at the date of application.
Accounts and tax documentation
- Evidence of the tax payable, paid and unpaid for the last full financial year
- The latest self-assessment tax return and the tax calculation from HMRC
- Proof of registration with HMRC as self-employed
- Accounts for the year. Audited accounts if you are required to produce them, otherwise unaudited accounts with an accountant's certificate
Bank evidence
Business bank statements for the same twelve-month period as the tax return, plus evidence of ongoing trading such as recent statements, invoices or contracts.
Combining self-employment with other income
Self-employed income can be combined with employment income, pension income and certain non-employment income. It cannot normally be topped up with cash savings.
Common evidence problems
- Applying before the tax return for the relevant year has been filed
- Bank statements that do not support the income declared
- Relying on turnover instead of profit
- No evidence that the business is still trading
Frequently Asked Questions
I only became self-employed this year. Can I sponsor my spouse?
Self-employed income can only be counted once you have a full financial year to rely on. Until then, other sources such as savings, or previous employment within the same financial year in some cases, may need to carry the application.
