Share your letter
Let us know what kind of notice you've had and when it's due back. No need to upload anything sensitive yet.
Talk it through
A specialist walks you through what's actually going on, lays out your options, and points you to the right expertise.
Move forward with a plan
From there, if you'd like to continue, your specialist takes over drafting replies and dealing with HMRC directly.
Most people give HMRC more than they've actually been asked for, out of anxiety. Slow down, read the request literally, and respond to that — nothing more.

Why go in with a specialist
Knowing the tax rules isn't the same as knowing HMRC.
HMRC enquiries run on procedure as much as tax law — response windows, information powers, and unwritten expectations about tone and pace. A specialist reads both sides of that equation, so what you send back doesn't accidentally invite more questions.
Talk through your case- An honest read on what's actually at risk
- Correspondence drafted with HMRC's process in mind
- Backup for meetings, evidence-gathering and negotiation
- A plan aimed at closing the enquiry, not prolonging it

Frequently asked questions
Common questions once the letter's arrived.
No two enquiries are quite the same — treat the below as general orientation, not advice for your specific case.
It's a formal review HMRC opens into a return you've already filed, checking that what you reported matches reality. In practice that can mean requests for records, explanations of specific entries, or a recalculation of what's owed.
Ready when you are
An unanswered letter doesn't stay small for long.
Give us the basics and we'll point you to the right kind of help for your situation.
