As of 13 August 2026, AI can work out when your UK business must register for VAT.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open the current GOV.UK VAT registration guidance and save the relevant pages or links, dated 2026-08-13.
   2. Export your sales ledger or invoices for the latest rolling twelve-month period and split the amounts into taxable, exempt, zero-rated, outside-the-scope and uncertain supplies.
   3. Add the dates and values of expected sales in the next thirty days, plus customer locations, goods or services supplied and any overseas, import, export or property transactions.
   4. Paste the business details, GOV.UK extracts and sales table into the prompt, keeping the original transaction dates and totals.
   5. Ask the model to show the rolling calculations, identify the applicable registration test and give the relevant date and application deadline without filling gaps by assumption.
   6. Compare every cited rule and threshold with the GOV.UK pages opened on 2026-08-13, and reconcile each calculated total with your sales ledger.
   7. Send the result and any uncertain transaction classifications to an accountant or tax adviser before acting if the business has overseas supplies, exempt activities, transfers, property transactions or incomplete records.
   8. If the conclusion is clear and your checks agree, follow the current GOV.UK instructions for registering and retain the evidence and calculations.

   Prompt

   Work out whether and when my UK business must register for VAT using the current GOV.UK guidance available on 2026-08-13. Do not guess a threshold, date, tax treatment or classification. If you cannot verify a rule from the GOV.UK extracts or links I provide, say so and tell me exactly what I need to check.
   
   Business details:
   - Business structure: [sole trader, partnership or limited company]
   - Business location and any overseas establishments: [details]
   - Main goods or services: [details]
   - Customers and their locations: [UK, EU, non-UK, business or consumer]
   - Existing VAT registration or VAT group status: [details]
   
   Evidence:
   - Monthly sales for the most recent rolling twelve-month period, split into taxable, exempt, zero-rated, outside-the-scope and uncertain amounts: [paste figures]
   - Any expected sales in the next thirty days: [paste figures]
   - Dates of the relevant invoices or supplies: [paste dates]
   - Any unusual transactions, acquisitions, transfers, land, property, imports or exports: [details]
   
   First, list any missing information and explain why it matters. Then use only the current GOV.UK rules to:
   1. identify which sales count towards the relevant VAT registration test;
   2. calculate the relevant rolling turnover and test the future-sales condition;
   3. state whether registration appears required, optional or not currently required;
   4. give the earliest relevant registration date and the deadline for applying, if the rules establish one;
   5. show every calculation in a table with the source figures;
   6. link to the GOV.UK pages used and quote the specific rule supporting each conclusion;
   7. list the assumptions and transactions that need a VAT accountant or tax adviser to confirm.
   
   Do not prepare or submit a VAT registration application. End with a short checklist of what I should confirm before relying on the result. This is not professional advice.
