Tax Audit Services That Find Problems Before HMRC Does
Tax errors do not stay hidden forever. HMRC is increasing its use of data analytics and targeted enquiries to find them. ABM Chartered Accountants delivers independent tax audits that review your corporation tax, VAT, and PAYE compliance before the taxman comes looking.
Your Tax Position Reviewed From Every Angle
A tax audit is an independent review of your tax computations, returns, and supporting records to check that you are paying the right amount of tax, claiming the right reliefs, and complying with all filing and reporting obligations. ABM Chartered Accountants carries out tax audits that cover corporation tax, VAT, PAYE, and more.
Our ICAEW and ACCA qualified accountants examine your tax returns against the underlying records, test your tax calculations, review your employment status classifications, assess your VAT recovery position, and identify any areas where errors, missed reliefs, or compliance gaps could expose you to penalties or HMRC challenge.
What Our Tax Audit Covers
From corporation tax computations to PAYE compliance, here is how ABM Chartered Accountants gives you confidence that your tax affairs are accurate, complete, and defensible.
Corporation Tax Review
Auditing your corporation tax computations and returns to check they are accurate and complete.
VAT Compliance Audit
Reviewing your VAT returns, records, and processes to identify errors before HMRC finds them.
PAYE & Payroll Audit
Checking your PAYE calculations, RTI submissions, and employment status classifications are correct.
Tax Risk Assessment
Identifying the areas of your tax affairs where risk of error or HMRC challenge is highest.
HMRC Enquiry Preparation
Preparing your records and position in advance so you are fully ready if HMRC opens an enquiry.
Tax Control Framework
Reviewing and strengthening the internal controls that govern how your tax obligations are met.
Stay Ahead of HMRC and Reduce Your Risk
HMRC’s compliance activity is intensifying. It is using Connect, its data analytics system, to cross-reference information from multiple sources and identify discrepancies. A tax audit from ABM Chartered Accountants puts you on the front foot by finding and correcting errors before they trigger an enquiry, reducing both your financial risk and your exposure to penalties.
A tax audit also uncovers missed reliefs and allowances. Many businesses overpay tax simply because legitimate claims have not been made or have been calculated incorrectly. We review your position to make sure you are not paying more than you owe and that every valid relief is claimed.

Frequently Asked Questions
Here are answers to the tax audit questions we hear most often. Contact our team for tailored guidance.
What is a tax audit?
A tax audit is an independent review of your tax computations, returns, and records. It checks whether you are paying the correct amount of tax, complying with filing requirements, claiming the reliefs you are entitled to, and whether your tax controls are working effectively.
Is a tax audit different from an HMRC enquiry?
Yes. A tax audit is a proactive review you commission yourself. An HMRC enquiry is an investigation initiated by HMRC, often triggered by discrepancies in your returns. A tax audit helps you find and fix problems before HMRC decides to look, reducing the risk of an enquiry altogether.
What taxes do you cover?
We cover corporation tax, VAT, PAYE, National Insurance contributions, construction industry scheme deductions, and employment status classifications including IR35. ABM Chartered Accountants reviews whichever taxes are relevant to your business and tailors the audit scope accordingly.
Can you find missed tax reliefs?
Yes. One of the most valuable outcomes of a tax audit is identifying reliefs and allowances that have not been claimed or have been calculated incorrectly. This includes R&D tax relief, capital allowances, annual investment allowance, and group relief. We recover what you are entitled to.
How often should we have a tax audit?
An annual tax audit is ideal, particularly if your business is growing, has complex tax affairs, or operates in a sector that HMRC targets for compliance activity. Some businesses opt for a review every two to three years. ABM Chartered Accountants recommends a frequency based on your risk.
How much does a tax audit cost?
Fees depend on the number of taxes being reviewed, the complexity of your affairs, and the size of your business. We offer fixed-fee pricing agreed before the audit begins. Contact ABM Chartered Accountants for a quote tailored to your needs.
