Updated: Changed the postal address for the form.
If you want to apply for Advance Assurance before your first claim for R&D tax relief you can:
- apply online (you’ll need to sign in or set up a tax account through the Government Gateway using the credentials that HM Revenue and Customs (HMRC) sent to your company when it registered for online filing)
- fill in the form on-screen (you can save a partly completed form), print and post it to HMRC
- fill in the form on-screen (you can only save this form once it’s fully completed)
Don’t use this form to make a claim for R&D tax relief or to make changes to an existing R&D tax relief claim.
When you’re filling in your application for Advance Assurance you’ll need:
- your company accounts
- your company registration documents from Companies House
- any HMRC correspondence
- previous company tax returns (not needed for new companies)
- the name of a main contact, for example a research manager or company director with direct knowledge of the company’s R&D
HMRC may ask the main contact, to discuss your application.
Please send postal forms to:
I & R Unit Manchester (AA)
Newcastle upon Tyne
