Attention January 2025 year-end companies – Submit your ANF before the end of July!

Contents

If this is your client’s first time claiming R&D tax credits (or they have not claimed in the last three years), they have to notify HMRC within six months of their year-end.

What does this mean?

If your client has a financial year-end in January 2025, the Advanced Notification Form (ANF) deadline is July 31, 2025 – it will be here before you know it!

Even if your client has conducted legitimate R&D activities, failure to submit the ANF when required will invalidate the claim.

ANF deadlines in 2025
