Tax Health Check · Clean up the past

Tax AI is already scanning. Are your old books waiting to be called out?

The tax office already uses AI to match invoices, returns and bank statements across years at once. The free check is the X-ray. Tax Health Check is the in-depth scan that finds exactly what needs cleaning up, and cleans it up before the machine finds it.

Tax Health Check

Like a CT scan

An expert reads every return, invoice, supporting document and journal entry of the last 3 years, and finds exactly which item, which year and how much.

Based on your real records
Risk quantified in numbers
A clean-up roadmap

Why only an expert can see it

Most tax risk does not sit in one wrong number but in how the numbers relate: invoices to contracts, the cash book to bank statements, returns to financial statements. A questionnaire cannot read those links.

Tax debt & compliance

FAQ

Frequently asked questions

How is Tax Health Check different from the free tax risk check?

Usually the tax returns, financial statements, accounting books, invoices, supporting documents and bank statements of the last 3 years. The exact list is sent once Kaizen has signed the confidentiality pledge.

Is our information kept confidential?

Yes. Kaizen signs a confidentiality pledge before receiving any document, and only the experts on your engagement can access your file.

How long until we get the report?

30 days after Kaizen receives the full file.

Can Kaizen carry out the clean-up after the check?

Yes. Kaizen carries out the clean-up following the roadmap in the report, quoted separately once you have seen the report.
