Why Outsource Your HMRC Investigation

HMRC letters can stop your day cold. You’re left wondering what triggered the check, what HMRC wants, and how serious it could get. The pressure grows because the rules feel unclear and the deadlines feel tight.

You get stuck with:

Long, drawn-out HMRC back-and-forth
Missed deadlines that make things worse
Rising penalties and interest
Confusing calls that push the case deeper
Hours spent digging through old records

We take control of the whole process by speaking to HMRC, reviewing your records, preparing replies, and guiding every step.

You get peace of mind, a clear plan, and a strong defence built on accurate numbers.

FAQ's

Why did HMRC contact me?

HMRC may contact you because of unusual numbers, missing records, random checks, or errors in past submissions. It doesn’t always mean you did something wrong. We review your case, explain the reason, and show you the exact steps to fix it.

Can you deal with HMRC on my behalf?

Yes. We handle all calls, letters, and replies once you authorise us, so you don’t speak to HMRC at all.

How much does it cost?

Each case is different. We give you a fixed quote after checking your HMRC letter and records. You don’t pay for insurance or yearly plans.

Can you help if another accountant filed my returns?

Yes. Most clients come to us for on-demand help even if someone else handled their books or tax.

What if my old accountant made mistakes?

We find errors, fix them, and explain them to HMRC with evidence so penalties stay lower.

How long will the investigation take?

Simple checks may close fast, while deeper cases take longer. We guide you through each stage and keep things moving.

Will HMRC visit my business?

It’s rare. Most cases stay on email, letters, or calls. If a visit is needed, we prepare you properly.
