Who Needs a Self Assessment Return

Common reasons include self-employment income over £1,000, rental income, untaxed income such as some dividends or interest, and capital gains to report. A high salary taxed through PAYE no longer means you must file on its own. See do you need to file a Self Assessment return? or use HMRC's tax return checker.

What Can Change the Fee

Your quote reflects how much is involved — for example several rental properties, capital gains, foreign income, more than one business, or catching up on earlier years.

Documents You'll Need

• Your UTR and any P60, P45 or P11D
• Dividend vouchers and interest statements
• Rental income and expense statements
• Self-employment income and expense records
• Pension contributions and Gift Aid donations
• Last year's tax return, if you filed one

Deadlines: 5 October, 31 January and 31 July
