Calculating tax credits

Tax credit awards are made up of a number of elements. The amount of any award depends on the elements that are included in the award and the household income.

Content on this page:

Overview

If you meet the qualifying conditions for child tax credit or working tax credit or both, the amount you actually get will depend on:

  • which elements of child tax credit and/or working tax credit you qualify for;
  • how much income you and your partner have (either for the current year or previous year); and
  • whether you are paying back an overpayment

The maximum amount

Tax credit awards are made up of a number of elements. There is information on our working tax credit and child tax credit pages which explain which elements might apply.

The elements are:

  • WTC basic element
  • WTC couple/second adult element
  • WTC 30 hour element
  • WTC childcare element
  • WTC disability element
  • WTC severe disability element
  • CTC child element (For children born on or after 6 April 2017, this may be limited to 2 children unless an exception applies)
  • CTC child disability element
  • disabled child rate
  • severely disabled child rate
  • CTC family element (* from 6 April 2017, this is only payable for claims which include a child/children born before 6 April 2017)

HM Revenue & Customs (HMRC) add together the elements which you qualify for to work out what your maximum tax credit award.

The amount and type of household income you (and any partner) have for the current tax year and previous tax year may reduce your maximum award and therefore the amount you are paid. The amount of award that is paid might also be less than the maximum you are paying back an overpayment.

If you are receiving income support, income based jobseeker’s allowance, income-related employment and support allowance, or pension credit, you should be paid your maximum amount. This does not apply if you are receiving any of these benefits during the four weeks after stopping work or reducing your hours of work to the point that working tax credit stops.

How awards are worked out

From your maximum award, HMRC take away a ‘reduction due to income’. There is information about what counts as income for tax credits purposes on our income page.

Working tax credit only awards

If you are only entitled to working tax credit because you or your partner are not responsible for a child or qualifying young person, then there will be a reduction due to income if your household income is above the £7,455 threshold.

This means, if your household income for tax credit purposes is less than £7,455, you will receive the maximum amount of tax credits. If your household income is above this amount, the maximum tax credits award is reduced by 41p for every £1 of income above the £7,455 threshold.

Example 1 – Working tax credit only award

John works 20 hours and claims working tax credit as a single person. He is self-employed and qualifies for the disability element. His income for tax credit purposes is £6,500.

John’s maximum tax credits are worked out first:

WTC basic element £2,280
WTC disability element £3,685
Total maximum £5,965

As his income is under the £7,455 threshold there will be no ‘reduction due to income’ and so John will receive the full £5,965 of WTC.

Example 2 – Working tax credit only award

Chrissie works 30 hours and claims working tax credit as a single person. She also qualifies for the disability element. Her income for tax credit purposes is £14,500.

Chrissie’s maximum tax credits are worked out first:

WTC basic element £2,280
WTC 30 hour element £950
WTC disability element £3,685
Total maximum £6,915

However, unlike John in the example 1, Chrissie’s income is above the £7,455 threshold which means that HMRC will reduce her maximum tax credits award. The reduction in income is calculated as follows:

Income £14,500
Less threshold £7,455
Excess income £7,045
X 41% £2,888.45

Chrissie’s maximum award of £6,915 will be reduced by £2,888.45 because her income is above the threshold. She will receive tax credits of £4,026.55.

Child tax credit only claims

If you are only entitled to claim child tax credit, because you do not work enough hours to qualify for working tax credit or you do not qualify for working tax credit for some other reason, then there will be a reduction due to income if your household income for tax credit purposes is above £18,725. If you have working tax credit elements included in your award, but do not receive any working tax credit payments because your income is too high, the £7,455 threshold will apply as explained below.

Above the £18,725 threshold, the maximum tax credits award will be reduced by 41p for every £1 of income.

Example 3 – Child tax credit only award

Devin and Mike claim tax credits as a couple. They have three children all born before 6 April 2017. Mike works 20 hours a week. They do not qualify for WTC because Mike is not working enough hours. Their income from Mike’s work, an occupational pension and some rental property they own is £22,000.

Their maximum tax credits award will be worked out first:

Child element standard rate x 3 £9,705
Family element £545
Maximum tax credits £10,250

However, because their income is above the £18,725 threshold for CTC only claims, HMRC will apply a reduction due to income which is worked out as follows:

Income £22,000
Less threshold £18,725
Excess income £3,275
X 41% £1,342.75

Devin and Mike’s maximum tax credits of £10,250 will be reduced by £1,342.75 to take account of their income. They will receive £8,907.25 of CTC.

Working tax credit and child tax credit awards

If you are entitled to both working tax credit and child tax credit, even if household income for tax credit purposes is too high to receive any working tax credit, then the £7,455 threshold will be used in working out any reduction due to income.

Income used to calculate an award

HMRC will use either previous year income or current income (actual income or an estimate if the year has not yet finished) to calculate a tax credit award and work out the reduction due to income (explained above). Our income page explains how HMRC decide which income figure to use when calculating your award.

Tax credit awards and daily figures

The rules around calculating tax credits awards are complicated. In our examples above, we have used the annual figures for each of the elements. This is common when showing examples. However, the HMRC computer system actually uses daily rates to calculate awards which means there may be a slight difference when compared to the annual figures.

You can find a detailed step by step guide to calculating awards using daily rates on our Revenuebenefits website for advisers.

Claiming universal credit

If you have been claiming tax credits and then claim universal credit during the same tax year, HMRC will stop your tax credit claim with effect from the day before the universal credit entitlement starts. The way your tax credit award for the year is calculated is based on the same principles explained on this page but the income figures used may be calculated in a different way. See our in-year finalisation page for more information.
