Corporate Tax & Transactions

Tax Due Diligence

A structured tax and accounting review supporting a proposed acquisition, disposal, investment or other significant business transaction.

Service overview

Tax Due Diligence is a structured review of agreed tax and accounting areas, carried out in connection with a proposed acquisition, disposal, investment or other significant business transaction.

The purpose is to give you a clearer picture of the tax and accounting position of the business being acquired, sold or invested in before you commit to the transaction. The review looks at the records and filings that exist, the tax matters they raise and any points that may need to be reflected in the transaction terms or dealt with after completion.

It is a different exercise from a Business Tax Health Check. A Business Tax Health Check reviews your own business's ongoing tax and accounting position. Tax Due Diligence is undertaken in connection with a proposed transaction, and the scope is set by the transaction rather than by a general review of the business.

We carry out tax due diligence for business buyers, sellers, investors and their advisers, working alongside solicitors and other transaction advisers where a transaction involves several parties. As an AAT Licensed Accountant, we confirm our fee by fixed quotation, so you know the cost before the work begins. VAT is not charged on our fees because we are not VAT registered.

Tax due diligence is not an audit or an assurance engagement, and it is not legal due diligence. It is a review of the tax and accounting information made available, within the scope agreed with you.

Our Tax Due Diligence service starts from £1,000. The final fee is confirmed by fixed quotation following an initial discussion about the transaction and the scope of the review, so you know the cost before any work begins. VAT is not charged on our fees because we are not VAT registered.
