Week 1: Revenue review
Check rolling revenue, customer requirements, current invoice format, and whether VAT registration is mandatory or voluntary.

SAMPLE TIMELINE
VAT registration timeline
VAT registration works best when the company prepares invoice controls before registration, not after the first PP30 deadline arrives.
Week 2: Document pack
Prepare company affidavit, office evidence, business proof, director documents, photos or signage where relevant, and accounting records.
Week 3: Registration process
Coordinate Revenue Department requirements and clarify any address or business-activity questions.
First month after VAT
Set PP30 calendar, output VAT log, input VAT folder, and tax invoice validation process.
COMMON MISTAKE
VAT aftercare is the real risk
Registering VAT is only the beginning. Monthly tax invoice discipline determines whether compliance remains clean.
Invoice format
Tax invoices must contain required details and be stored consistently.
Input VAT evidence
Purchase VAT should be supported by valid tax invoices, not only receipts or screenshots.
Deadline control
PP30 preparation should start before the filing date, not on the final day.
