Registration for HMRC Tax Assistance

Because the deadline for submitting the 2025 HMRC Self Assessment does not allow sufficient time to issue a Letter of Engagement, you will be asked to register a one-off Tax Assistance Agreement.

This allows us to legally represent you for your 2025 Self Assessment tax return.

Here are a few simple steps to follow:

1. Sign the Tax Assistance Agreement

2. Provide your taxpayer information

3. Upload the required documents
