You’ll need to send a tax return if any of the following apply, in the last tax year

• You were self-employed – you can deduct allowable expenses
• You got £2,500 or more in untaxed income, for example from tips or renting out a property – contact the helpline if it was less than £2,500
• Your income from savings or investments was £10,000 or more before tax
• Your income from dividends from shares was £10,000 or more before tax
• You made profits from selling things like shares, a second home or other chargeable assets and need to pay Capital Gains Tax
• You were a company director – unless it was for a non-profit organisation (such as a charity) and you didn’t get any pay or benefits, like a company car
• Your income (or your partner’s) was over £50,000 and one of you claimed Child Benefit
• You had income from abroad that you needed to pay tax on
• You lived abroad and had a UK income
• Your taxable income was over £100,000
• You were a trustee of a trust or registered pension scheme
• You had a P800 from HMRC saying you didn’t pay enough tax last year – and you didn’t pay what you owe through your tax code or with a voluntary payment
• Your State Pension was more than your Personal Allowance and was your only source of income – unless you started getting your pension on or after 6 April 2016.

Certain other people may need to send a return (for example ministers of religion or Lloyd’s underwriters) – you can check whether you need to. You usually won’t need to send a return if your only income is from your wages or pension.
