Real numbers

You probably don't owe what you think

Most first-time filers overestimate their tax bill. We typically find £200–£600 of legitimate expenses you forgot about (mileage, equipment, professional subscriptions, use-of-home, training). For first-time CIS sub-contractors, the average refund is £600–£1,800 — yes, HMRC may owe you.

Honest answers

You probably want to know

Do I actually need to file?

You must file if any of: self-employment income > £1,000; rental income > £1,000; untaxed savings interest > £500; dividends > £500; capital gains over the £3,000 exempt amount; total income over £100k; partner in a partnership; HMRC has registered you for SA. Email us your situation — we'll tell you in 5 minutes.

When is my first return due?

For income earned in tax year ending 5 April 2025, the online filing deadline is 31 January 2026. Tax owed is due by the same date. Late filing = £100 instant penalty even if you owe £0.

What records do I need?

Bank statements, sales invoices/receipts, expense receipts, P60/P45 if employed, dividend vouchers, savings interest summaries, rental income/expense records. Photos work fine. We'll send a checklist when you sign up.

I missed registering with HMRC. How bad?

You're supposed to register by 5 October following the end of the first tax year you owe. Missing this is a £100 penalty BUT we usually argue this down to £0 with a "reasonable excuse" letter. We handle the registration regardless.

Can I do it myself for free?

Yes. HMRC's online form is free if you've got the time and confidence. Most first-timers find £79 saves them hours of confusion plus catches deductions they'd miss — typically a net win. Your call.
