What are tax credits?

And now that you know how to contact HMRC tax credits helpline or seek advice online, let’s chat about what tax credits actually are.

Tax credits are a state benefit provided by HMRC. They are there to support people on low incomes and those with children. Whereas tax deductions and exemptions reduce the amount of taxable income, tax credits reduce the amount of tax owed.

In the UK, there are two types of tax credits.

  • Working tax credit is available to employed people who are on low incomes, regardless of whether you have a child or not. That includes both employed workers and self-employed. Furthermore, tax credits include separate tiers for circumstances such as disability and childcare payments.
  • Child tax credit is eligible to all UK residents who have children. In reverse, you can be entitled to child tax credits whether or not you are employed.

We’ve compiled everything you need to know about tax credits before you dial the tax credits helpline number.

How much can you earn and still get tax credits?

Please note that tax credits are subject to your individual circumstances, so there is not a specific income threshold.

You can use the tax credit calculator on the HMRC website to work out an approximation of what you can earn. Then, you find apply and receive more personalised information using the tax credits payment helpline.

At present, the maximum annual amount for basic working tax credits is £3,040. If your household income is £6,530 or below, you could receive this amount. If you earn above this amount, your tax credits are reduced by 41 pence for every £1 you earn.

Essentially, the more you earn, the fewer tax credits you are entitled to.

In terms of child tax credits, you are not eligible if you fit the following criteria:

  • Children born before 6 April 2017
  • You have one child and a household income of £25,000+

Meanwhile, if you have two children born before  6 April 2017 then the maximum you can earn to get credits is around £35,000 per annum. Ultimately the best way to find out what you are entitled to claim is to call the child tax credit helpline or use the online calculator.

If your details are correct you needn’t do anything else, and your tax credits will be automatically renewed. You must tell HMRC immediately if your circumstances have changed or anything in your pack is incorrect.
