Which SA pages apply to which income
Freelancers often have multiple income streams: primary self-employment, occasional side jobs, rental income, dividends from a small Ltd, foreign income from remote clients. Each has its own SA supplementary page. This guide covers which pages apply to which income type and how to keep the reporting clean when your income has three or four sources.
Which SA pages apply to which income
Main self-employment: SA103S (short) or SA103F (full). Employment income: SA102. UK property rental: SA105. Foreign income (including foreign self-employment): SA106. Capital gains: SA108. Partnership income: SA104. Dividends from your own Ltd (as director/shareholder): on the main return, under 'Interest and dividends from UK companies'. Bank interest: on the main return.
The 'Tailor your return' section at the start of the SA online journey asks which apply; tick every relevant one.
Ordering the reporting
Report the largest income source first (main self-employment for most freelancers), then smaller streams. HMRC's calculator handles the maths regardless of order, but it's easier to spot errors when the biggest number is at the top.
For each stream, gather records separately: bank statements filtered by client, platform payout reports (Fiverr, Upwork, Etsy), rental income tracker, dividend vouchers from any Ltd, bank interest statements.
When multiple streams complicate the calculation
Personal allowance interaction. Your £12,570 applies to total income. If PAYE has already used it, the freelance stream is fully taxed from £0.
Higher-rate threshold crossings. If combined income crosses £50,270, part of the top stream may be higher-rate — even if no single stream individually would be.
Dividend + salary from own Ltd. These interact with the dividend allowance (£500) and are taxed at dividend rates, not employment rates.
Foreign income and double-tax relief. Foreign tax paid abroad can usually be credited against UK tax; SA106 handles the mechanics.
Worked example
Total income: £58,000. Personal allowance £12,570 applied to PAYE first (already deducted at source). Freelance profit £20,000 taxable from £0 — most at 20%, but the top slice crosses £50,270 higher-rate threshold: £30k+£20k=£50k, then rental £8k stacks on top — of which £270 stays in basic rate and £7,730 hits higher-rate. Income tax on freelance: £20,000 × 20% = £4,000. Income tax on rental: £270 × 20% + £7,730 × 40% = £54 + £3,092 = £3,146. Class 4 NI on freelance: (£20,000) × 6% = £1,200 (personal-allowance portion already used by PAYE). Total extra tax + NI beyond PAYE: £8,346.

Multi-stream SA checklist
- List all income streams for the tax year
- Match each to its SA supplementary page
- Tick every applicable page in the 'Tailor your return' step
- Keep records separately per stream
- Confirm any foreign tax credited (SA106)
- Confirm any allowable expenses claimed per stream (each stream has its own expense rules)
- Review whether combined income triggers higher-rate — plan accordingly
- Consider whether Ltd + salary structure would simplify or complicate
Yes — expenses attach to the stream they were incurred for. A courier fee for your Etsy side hustle can't offset your consulting income.
Yes — sole-trader self-employment can be cash basis; rental income can be accrual. Each stream reports on its own basis.
SA calculates repayment on total income above the plan's threshold. If PAYE already deducted some, HMRC reconciles at year-end.
Amend your return within 12 months of the original filing deadline. Beyond that, disclose via HMRC's Digital Disclosure Service for reduced penalties.
The £1,000 trigger applies to total tax owed across all streams. If combined tax > £1,000 and less than 80% is at source, POAs apply.
