If you have claimed a relevant disability benefit that will give you entitlement to WTC (including the disability element) you need to make your claim for WTC within 31 days of the decision on your disability benefit.If you make the claim within 31 days, your WTC will be backdated to the start date of your disability benefit (as long as you met the other qualifying conditions for WTC during that period) or, if later, the date you started to meet the other qualifying conditions for WTC.If she does not make the claim within those 31 days, she can still claim WTC but will only receive 31 days' backdating.If you now qualify for extra elements to be included because you (or someone in your family) start getting a qualifying benefit, you should contact HMRC straight away so they can be added to your claim.If you think you should have received backdating and have not, then once you get your first award notice you will need to ask for the decision to be reconsidered, and if necessary, then appeal the decision.See our 'appeals section' for information on how to do this.If you are claiming child tax credit (CTC) only or CTC and working tax credit (WTC), this should happen automatically.
Some people may only qualify for WTC if they meet the criteria for the disability element of WTC.
The date you are paid tax credits from is usually the date HMRC receive your claim form – this is your date of claim.
However, you can be paid for an earlier period in certain circumstances. The Government is gradually introducing universal credit, a new benefit which will eventually replace tax credits, and some other social security benefits.
If you met the rules for the new elements before you told HMRC about the change, they can backdate the change to your award up to 1 month, but you will need to ask for this.
Back to the top Some claims (and changes of circumstances) can be backdated longer than 31 days.
If you have already had a backdated payment of a social security benefit reduced because of this, you should be paid the full backdated amount of tax credits.
