Who needs to complete a tax return?
These are the most common reasons for needing to fill in a tax return:
You are self-employed or a partner in a partnership
You need to complete a tax return even if you make a loss or if it's your final year of trading.
You are a company director, a minister of any faith, Lloyd's name or member
The only exception is if you're a director of a non-profit organisation, for example a charity, and don't receive any payments or benefits)
Your annual income is £100,000 or more
If you receive total income of £100,000 or more you'll need to complete a tax return. You may have higher or additional rate tax to pay that hasn't been collected through your tax code.
You have income from savings, investment or property
If you are an employee or a pensioner and already pay tax through a PAYE code, you can sometimes ask for tax that you owe on income, such as savings and property, to be collected through your code number. You'll need to complete a tax return instead if the income you receive is:
- £10,000 or more from taxed savings and investments
- £2,500 or more from untaxed savings and investments
- £10,000 or more from property (before deducting allowable expenses)
- £2,500 or more from property (after deducting allowable expenses)
If you don't pay tax through a PAYE code you’ll need to complete a tax return if all of the following apply:
- you have income to declare, for example income from savings, trusts or abroad, rental income from land or property
- your total income exceeds your total allowances and reliefs
- you have tax to pay on this income
You need to claim expenses or reliefs
If you're employed and want to claim expenses or professional subscriptions of £2,500 or more, you'll need to complete a tax return. If you want to claim expenses below this amount, you can contact HMRC.
You can only claim certain reliefs, such as Enterprise Investment Scheme relief or relief on Venture Capital Trusts, by completing a tax return.
You or your partner receive Child Benefit and your income is over £50,000
The new High Income Child Benefit tax charge, introduced on 7 January 2013, may mean you need to complete a Self Assessment tax return for the first time. You must complete a tax return if all of the following apply:
- your income is over £50,000 a year
- you live with a partner and your income is higher than theirs
- you or your partner are entitled to receive Child Benefit (or get an equivalent amount from someone who claims Child Benefit for a child who lives with you)
- you jointly decide to keep receiving Child Benefit and pay the new tax charge
You are 65 and receive a reduced age-related allowance
If you receive a reduced age-related allowance, you'll usually need to complete a return if your income is over a certain level (£24,000 for the 2011-12 tax year, and £25,400 for the 2012-13 tax year). But there are exceptions, for example if your tax affairs are very straightforward.
You get income from overseas
You must complete a tax return if you have any foreign income that's liable to UK tax.

You must complete a return if you receive income (or are treated as receiving income) on which tax is still due, for example from:
- annual trusts or settlements
- the estate of a deceased person
You have Capital Gains Tax to pay
