How it works


Import your information

Connect Xero, or easily import from any other account software, and add your project information.

We do all the work for you

Claimer’s expert tax and tech team maximise your claim by reviewing your financials & project, before writing the report and submitting it to HMRC.

You get paid

If you're due a tax credit or refund, the money is sent to you as soon as the claim is paid by HMRC, between 1-5 weeks later.

Don't just take our word for it

  • The product makes a complex process feel easy and straightforward. I'd recommend to anyone and no doubt we'll be continuing to use them for years to come.

    Dealing with Claimer was a pleasure and Adam and Ben were incredibly helpful and knowledgeable throughout the process with a deep understanding of the R&D tax rules and claim process.

    Great team, great service and really simple process. Completing the R&D details was really easy and the claim went through without a hitch. Definitely recommend these guys.

    So easy. Having been through this before with accountants that over complicated the process to justify their 20% fee, Claimer was a breath of fresh air.

The new way of claiming R&D Tax Credits

Goodbye R&D admin

No more long word documents, endless calls, and excel spreadsheets to fill in. We minimise your time input.

Unrivalled support

At Claimer, you come first. During the day, our team aims to answer all live-chat questions within 2 minutes.

We only get paid when you do

Peace of mind

In the unlikely event HMRC decide to query your claim, we’ll handle all communication.

No more waiting

If you can’t wait, we can provide a bridging loan before HMRC pays out. Speak with us to find out more.
