What Self-Employed Parents Should Check
The Minimum Earnings Test
You, and your partner if you have one, must each expect to earn at least the National Minimum Wage or Living Wage for 16 hours a week. If you're 21 or over, that means at least £2,643.68 over the next 3 months.
Self-employed income often comes in uneven amounts, so you can use your expected average earnings over the tax year instead. GOV.UK gives the example of someone aged 21 or over who earns £10,574.72 over the year, which works out at the same average.
If you started your business less than 12 months ago, it doesn't matter how little you earn. If you're both employed and self-employed, you can add your earnings together, or use only your self-employed income if that's what gets you over the threshold.
Some income doesn't count towards the test, including dividends, interest, pension income and income from property. That means landlords need earnings from a job or self-employment as well as their rental income.
The £100,000 Income Limit
You can't claim if you or your partner expect adjusted net income above £100,000 for the current tax year, which is 2026-27. Adjusted net income is broadly your total taxable income after certain reliefs. For a sole trader, that means your profit, not your turnover.
That makes accurate records worth having. Claiming every allowable expense you're entitled to as a sole trader keeps your profit figure right. Childcare itself isn't a business expense, though, so it doesn't go on your return.
If your profits are rising towards the limit, a running estimate helps. Keeping your books digitally, as our guide to HMRC digital record keeping rules for freelancers explains, means you can check your profit at any point in the year.
What You Need to Apply
You'll need your National Insurance number. If you're self-employed, you'll also need your Unique Taxpayer Reference (UTR), the reference HMRC gives you when you register for Self Assessment. If you're new to self-employment, here's how to register for Self Assessment with your Government Gateway login.
You'll also need your child's UK birth certificate reference number, if you have one, and the date you started work. If you live with a partner, you must include them in the application too.
If you're starting or returning to work, your start date affects when you can apply. For example, if you start between 1 October and 31 January, you can apply from 1 September. If you live in England, HMRC will also check whether you qualify for Free Childcare for Working Parents when you apply.
If You Get Universal Credit or Childcare Vouchers
You can't get Tax-Free Childcare at the same time as Universal Credit or childcare vouchers. The childcare calculator on GOV.UK can show you which option suits you better.
If you switch from vouchers, you must tell your employer within 90 days of applying. If you're on Universal Credit, wait for a decision on your Tax-Free Childcare application before you cancel your claim.
