Claiming R&D tax relief is a crucial financial boost for innovative businesses in the UK. However, with the introduction of the Advanced Notification Form (ANF), companies must now be more proactive to secure their claims. In this blog, we will guide you through everything you need to know about the ANF, from eligibility and submission to expert insights and future developments.
The Advanced Notification Form (ANF) is a new requirement introduced by HMRC to streamline and monitor R&D tax relief claims. It acts as an early declaration of a company’s intention to claim R&D tax relief for a particular accounting period. Essentially, it is a formal notification that alerts HMRC to expect a claim.
The ANF ensures transparency and helps HMRC manage claims more efficiently. For businesses, submitting the ANF is now critical because, without it, they risk losing eligibility for R&D tax relief altogether, particularly if they are making a claim for the first time or have not claimed in recent years.
If you’re planning to claim R&D tax relief or expenditure credit for accounting periods beginning on or after 1 April 2023, you must submit a claim notification form if:
If your company has been consistently claiming R&D tax relief without gaps, you might not need to submit an ANF. However, if unsure, it is always best to confirm.
To be eligible, your company must:

Common pitfalls include:
Attention to detail is crucial to avoid delays or rejections.
Submitting the ANF ensures your company is eligible to claim R&D tax relief. It also demonstrates a level of organisation and professionalism that HMRC values, potentially leading to a smoother review process.
Failure to submit the ANF when required means your company will be barred from claiming R&D tax relief for the accounting period in question. Correct and timely submission safeguards your ability to benefit from generous tax relief opportunities.
Q: Can I edit my ANF after submission?
A: No, you cannot edit a submitted form. Ensure all details are accurate before submission.
Q: What if I submit the ANF late?
A: You will not be able to claim R&D tax relief for that period.
Q: Is an ANF needed every year?
A: No, only if you are a first-time claimant or have not claimed in the last three accounting periods.
The UK government has signalled ongoing reforms to R&D tax credits, including closer scrutiny of claims and efforts to combat fraud. While no immediate changes to the ANF process have been announced, businesses should stay vigilant as updates can happen quickly.
The ANF is now an essential step for many companies wishing to benefit from R&D tax relief. Being proactive, thorough, and timely will ensure your company can access the support it needs to innovate and grow. If you are uncertain about the process, professional advice is highly recommended to avoid costly mistakes.
