# How Much Must You Earn to File Self Assessment? 2026/27

**There is no single earnings level at which everyone must file Self Assessment.** A return depends on the source and gross amount of income, capital gains, tax charges, relief claims and whether HMRC has issued a notice to file.

## The £1,000 self-employment test

If gross self-employment or casual trading income exceeds £1,000 in a tax year, you normally need to register and file. Gross means before expenses. At £1,000 or less, the trading allowance can give full relief subject to restrictions.

## Property income

Gross property income over £1,000 can require reporting. HMRC’s route depends on gross receipts, taxable profit and other circumstances. The property allowance, Rent a Room relief and joint ownership have separate rules.

## PAYE salary

Most people whose only income is correctly taxed through PAYE do not need a return, regardless of salary alone. High income can still create:

- Personal Allowance tapering above £100,000;
- High Income Child Benefit Charge above £60,000 adjusted net income;
- pension annual allowance issues;
- tax on untaxed benefits or other income;
- relief claims not handled through payroll.

HMRC has changed historic high-income filing thresholds, so use the current checker.

## Savings and dividends

Interest and dividends use separate allowances and 0% bands. Whether a return is needed depends on amounts, tax band, other income and HMRC collection method. Foreign income can require reporting even where tax was paid overseas.

## Capital gains

Taxable gains can require a return even with low earnings. The annual exempt amount is £3,000 for 2026/27. UK residential-property gains normally also require reporting and payment within 60 days of completion.

## Child Benefit charge

Adjusted net income above £60,000 can trigger the High Income Child Benefit Charge, reaching full clawback at £80,000 under current rules. HMRC may provide a PAYE service for some taxpayers, but check whether Self Assessment is required.

## Foreign income

UK residents can be taxable on worldwide income. Small foreign-income exemptions, treaty relief and residence rules are fact-specific. Earnings below the Personal Allowance do not automatically make foreign income non-reportable.

## Why the Personal Allowance is not a filing threshold

The standard Personal Allowance is £12,570, but it only affects how much taxable income is charged. Someone can need a return with income below it, while a PAYE employee earning much more may not.

## Notice to file

If HMRC sends a notice, file unless HMRC withdraws it. A nil liability or low income does not cancel the notice automatically.

## Examples

**Side business:** £1,200 gross sales and £900 expenses. A return is normally required because gross income exceeds £1,000, even though profit is £300.

**Employee:** £70,000 salary correctly taxed through PAYE, no Child Benefit, gains or untaxed income. A return may not be required solely because of salary; use HMRC’s checker.

**Landlord:** £8,000 rent and £7,500 expenses. Reporting may be required despite £500 profit because gross property income exceeds £1,000.

## Registration and filing deadlines

- notify HMRC by 5 October after the tax year;
- paper return by 31 October;
- online return and payment by 31 January;
- second payment on account by 31 July where applicable.

## Making Tax Digital thresholds

MTD for Income Tax uses qualifying gross self-employment and property income: above £50,000 from April 2026, above £30,000 from April 2027 and above £20,000 from April 2028. These are MTD thresholds, not universal Self Assessment filing thresholds.

## Decision checklist

1. List income by source.
2. Test gross trading and property income against £1,000 allowances.
3. Review gains, foreign income and Child Benefit.
4. Check pension charges and relief claims.
5. Use HMRC’s current checker.
6. Respond to any notice to file.
