We stand beside Polish businesses when HMRC gets involved.

Have you found an error in one of your tax returns?

Even when you have taken care, a tax return can still contain an error. We review the figures and evidence, identify the correct route and explain the likely tax, interest and penalty position.

With your approval, we prepare the amendment or claim, submit it to HMRC and deal with any questions. You know what is being corrected, why it matters and what happens next.

Has HMRC started a compliance check?

An HMRC compliance check can feel overwhelming, especially when the letter asks for records or explanations by a fixed date. We read the opening letter, confirm the scope of the check and help you understand what HMRC is asking and why.

Once authorised, we organise the evidence, prepare clear responses and communicate with HMRC on your behalf. We keep you informed, address points that are not supported by the facts and guide the case towards a properly documented conclusion.

Can your HMRC penalty be challenged?

An HMRC penalty is not always the end of the matter. We check the notice, calculation, deadline and whether a reasonable excuse or another ground of appeal may apply.

We prepare the appeal, organise the evidence and explain the realistic outcomes before anything is submitted. Acting early helps protect your options.

What our HMRC support gives you:

Clarity: you understand the letter, the risk and the next deadline.
Control: we organise the facts, documents and response so nothing important is missed.
Representation: once authorised, we communicate with HMRC and answer questions on your behalf.
A stronger position: your response is supported by clear calculations, relevant evidence and the facts of your case.

What you can expect from TaxOne:

Confidentiality: your information is handled securely and discreetly.
Prompt action: we identify the first deadline and tell you what is needed immediately.
Plain English: we explain the position, options and risks without unnecessary jargon.
Evidence based responses: every submission is built around the available records and facts.
Your approval: nothing is sent to HMRC until you understand and approve it.

Know what HMRC expects

We do more than answer one letter. We explain what HMRC is checking, why particular records matter and what can reduce future risk. You finish the process knowing which documents to keep, which deadlines matter and when to ask for advice before a small issue becomes a bigger one.

HMRC letter, enquiry or penalty? We help you regain control.
