No, Maternity Allowance does not go on your tax return. It is a wholly tax-free social security benefit, so you leave it out of every income box on Self Assessment, including the section for taxable state benefits. If Maternity Allowance was the only money you received in the tax year and you have no other filing obligations, you may not need to submit a return at all.
Why It’s Tax-Free
Maternity Allowance is listed as a wholly exempt social security benefit under Section 677 of the Income Tax (Earnings and Pensions) Act 2003, which sits within Part 10, Chapter 5 of that Act covering UK benefits that carry no income tax liability.1Legislation.gov.uk. Income Tax (Earnings and Pensions) Act 2003 – Part 10 Every pound you receive is yours to keep. It is not added to your other income when HMRC works out your tax bill, and it cannot push you into a higher tax band.
Where It Goes on Self Assessment
Nowhere. Do not enter Maternity Allowance in any income box, and in particular do not put it in the “Other Taxable State Benefits” section. That box is for benefits Parliament has chosen to tax, such as Statutory Maternity Pay and the State Pension. Maternity Allowance is not one of them.
The most common error is entering the payments in that state benefits box out of a reasonable instinct to report everything. Doing so tells HMRC’s system to treat the amount as taxable income and calculate tax on it. You then either overpay or have to contact HMRC to unpick the mistake, which can take weeks.
If you have self-employment income alongside Maternity Allowance, report only the self-employment income on the return. Maternity Allowance also has no effect on your £1,000 trading allowance, because that allowance applies to trading and miscellaneous income, not state benefits. The two are calculated separately.
Statutory Maternity Pay Is Different
Statutory Maternity Pay and Maternity Allowance sound similar and both support you around the birth of a child, but they are taxed in opposite ways. The distinction decides whether anything appears on your return.
Statutory Maternity Pay comes through your employer’s payroll. Your employer deducts Income Tax and National Insurance before the money reaches your account, just like regular wages.2GOV.UK. Maternity Pay and Leave – Pay If you are employed with at least 26 weeks of continuous service with the same employer and average weekly earnings of at least £129, you receive Statutory Maternity Pay rather than Maternity Allowance. Because it is earnings taxed through PAYE, it feeds into your P60 and, if you file Self Assessment, into the employment pages of your return.
Maternity Allowance comes directly from the Department for Work and Pensions. You typically qualify if you have been employed or registered as self-employed for at least 26 weeks in the 66 weeks before your due date but do not meet the Statutory Maternity Pay conditions. Self-employed workers earning at least £30 a week in at least 13 of those weeks are the most common recipients.3GOV.UK. Maternity Allowance – Eligibility Because it is a welfare benefit rather than earnings, it arrives without deductions and stays off your tax return.
The gap in your pocket is real. On weekly payments of £184.03, a basic-rate taxpayer loses roughly £36.80 to Income Tax alone from Statutory Maternity Pay before National Insurance. Maternity Allowance at the same rate pays out in full. Knowing which one you are on tells you what to expect at the bank and what, if anything, to put on the return.
Effect on Your Other Income and Benefits
Receiving Maternity Allowance does not change how your other income is taxed. Freelance work, rental income, and investment returns during the same tax year remain taxable in the normal way. Maternity Allowance sits outside the calculation entirely: it does not use up your Personal Allowance, does not affect your tax band, and does not reduce entitlements calculated on taxable income.
One boundary worth flagging, because it catches people who assume tax-free means neutral everywhere. If you claim Universal Credit as well, Maternity Allowance reduces your Universal Credit pound for pound. That is a benefits calculation, not a tax one, and it happens whether or not the payment appears on any return.
Maternity Allowance also carries Class 1 National Insurance credits for each week you receive it, awarded automatically as part of the claim.4GOV.UK. Maternity Allowance – What You’ll Get For self-employed claimants that is worth checking against your accountant’s workings, so you are not paying voluntary Class 2 contributions for weeks already covered by the credits. Again, none of this touches the tax return itself.
