What happens when a VAT number changes?

A VAT number can be valid today and no longer valid tomorrow. So how confident are you that the VAT data sitting in your systems is still accurate?

For tax teams, VAT validation can often feel like a fairly straightforward exercise. A new customer or supplier provides a VAT number, you check it against the relevant source, it comes back as valid, and everyone moves on.

But what happens six months later?

The business might have changed, a VAT registration could have been cancelled, the company is no longer trading or the information held in your ERPEnterprise resource planning (ERP) is a type of software that organisations use to manage main business processes. simply might not reflect what’s currently held by the tax authority. And that’s where things can get a little more complicated.

VAT numbers are not static!

Business can change all the time as they enter new markers, leave others, register for VAT, deregister or restructure. The VAT registration that was perfectly valid when it was first checked isn’t necessarily going to remain that way indefinitely.

For a tax team managing VAT registrations across multiple entities and countries, keeping on top of those changes manually can quickly become a job in itself.

And it’s not just about whether a number is technically valid. You might also need to know whether the registration is still active, whether it belongs to the entity you think it does, or whether something has changed that needs investigating.

This is particularly important when you consider how much tax data sits downstream of your master data. If an old or incorrect VAT registration is sitting in your ERP, it isn’t necessarily going to flag itself up when something changes. It can continue to be used until someone notices there is a problem.

So perhaps the better question is ‘can we still trust the VAT numbers we’re using?’

Rather than treating VAT validation as a one-off check, tax teams need a way to keep an eye on their registration data over time and identify when something has changed. If a VAT registration is deregistered, for example, you want to know about it. And if a record looks different from what you expected, your team needs to be able to spot it and decide what to do next.

This is one of the areas where LimeLyte® Entity Manager (LLEM) has evolved.

LLEM can help tax teams move beyond simply checking whether a VAT number is valid, towards actively managing the information they hold. VAT registration data can be monitored over time, with changes and discrepancies identified so that records requiring attention can be reviewed.

It can also help identify situations where a company is no longer active or a VAT registration has been deregistered, giving tax teams another way to spot records that may need to be investigated or updated.

And that’s important because you don’t necessarily want your tax team spending their time manually checking every single VAT registration they hold.

It’s traffic light system can make a real difference. Rather than working through a long list of records and trying to work out which ones need attention, clear status indicators can help highlight exceptions and focus your team’s time where it’s actually needed.

The result is a more practical approach to VAT data maintenance: validate the registration, monitor it over time, identify changes and exceptions, and give your team the information they need to decide what to do next.

As businesses become more global, with more entities more data sources to manage, that ongoing maintenance becomes increasingly important.
