We will conduct an internal financial audit of your company

Can 12 months of bookkeeping errors be corrected in around one month?

In many cases, we can review a full year of records and prepare the required corrections in around one month, once we have the complete documents and relevant authorisations. The exact timescale depends on the number and type of errors.

We identify what went wrong, agree which accounts or returns need attention and keep you informed throughout. You provide the records and answer our questions. We manage the agreed correction process.

What does a business tax health check involve?

We start by listening to your concerns and agreeing which periods, taxes and filings need to be reviewed.
We examine the bookkeeping records, bank transactions, supporting documents, accounts and returns available for the period.
With your authorisation, we act as your tax agent and obtain the information needed from HMRC.
We identify errors, inconsistencies, missed claims and areas that may create additional tax, interest or penalties.
You receive a clear explanation of what is wrong, what the likely impact is and which issues should be corrected first.
Where required, we prepare amended accounts or returns and submit them to Companies House or HMRC using the appropriate process.
Once the immediate problems are resolved, we show you how to improve the records and controls so the same errors are less likely to return.

What happens if the business tax health check uncovers further problems?

Finding more than one issue does not mean you lose control. We rank each problem by urgency and give you a clear correction plan, expected timescale and cost before any additional work begins.

If a previous accountant's work may have caused a financial loss, we can help document the errors and quantify their impact. We will explain whether a formal complaint or separate legal advice may be appropriate.

You can also read examples of complex tax and accounting cases in our tax blog.

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.
