Preparing for the VAT registration site inspection: what must be at the address

A checklist of what genuinely has to exist at your place of business when a Revenue Department officer inspects it before approving VAT registration: signage, proof of the right to use the address, a location map, photos, and someone on site to confirm the facts.

Short answer

Before approving VAT registration, a Revenue Department officer normally inspects the place of business to confirm the address is genuinely used. Have ready: a permanent, visible company sign, proof of your right to use the premises, a route map and building photos, original company documents, and a person who can answer questions about the business on the day. If the sign is missing or nobody is there, the file is usually parked and re-inspected later, pushing VAT approval back by weeks.

Step by step

How this works in practice

  1. 01

    Confirm the address you will register

    The filed address must be genuinely usable and inspectable. If you use a registered-address service, it must be one that supports inspections, with real workspace and on-site staff.

  2. 02

    Install the company sign before filing

    The name on the sign must match the affidavit exactly, including the company/limited wording. Paper or temporary stickers are a frequent reason for rejection.

  3. 03

    Keep an original-document file on site

    Affidavit, shareholder list, director ID, lease or consent letter, and power of attorney — one folder the officer can review immediately.

  4. 04

    Take photos and draw the route map

    An exterior shot where the sign is legible, interior shots showing desks and equipment, and a map with nearby landmarks so the officer can find the place.

  5. 05

    Make sure someone is there on working days

    Visits are often unannounced. Keep an authorised person available during business hours with a phone number that is always answered.

What goes wrong

Reasons this gets delayed or rejected

Sign does not match the registered name

Using a trade name or an abbreviation means the officer cannot confirm it is the same company.

The address is only a mailbox

An address with no usable space and nobody present will not pass, and can affect later filings too.

Incomplete consent documents

Missing the owner's title deed copy or ID leaves the file waiting for paperwork that could have been ready.

Questions

Answers to the questions we hear most

When is VAT registration required?

When taxable revenue reaches the statutory threshold, or voluntarily when the business needs to issue tax invoices. Check the current threshold with the Revenue Department.

Is the inspection scheduled in advance?

Some offices call ahead, others simply arrive. Keep the premises inspection-ready throughout business hours after filing.

Can a home address be used for VAT?

Yes, if the owner consents and the place is genuinely usable for business. Signage and inspection rules still apply, and condo or village regulations should be checked first.

What if the place of business moves after VAT registration?

File the prescribed change notification with the Revenue Department within the deadline; a fresh site inspection may follow.
