Once you get in touch, we review your HMRC letter, explain what the issue is, and outline your options. You’ll understand whether the problem is routine, urgent or incorrect, and what HMRC is actually asking for. If you need help responding, gathering evidence or challenging a decision, we can handle that too.

When to reach out
When to reach out
If HMRC has contacted you and you’re not confident about how to respond, that’s the right time to speak to us. Many clients reach out before calling HMRC so they know exactly what to say and what to avoid. Early clarity can make a big difference to the outcome.
