VAT in commercial property: common errors

VAT errors in commercial property often relate to changes over time: use of space, vacant premises, tenants and documentation that no longer reflects reality.

VAT is one area of commercial property that can create both misunderstandings and financial risk. Often, nobody is trying to get it wrong. The property changes, while the documentation remains tied to an earlier version of reality.

VAT control means keeping floor-area use, tenant status and documentation up to date over time.

1. Changes in how space is used

VAT assessments are often made when the use of space seems clear. Then a tenant moves, premises are refurbished or a common area is used differently. If the assessment is not updated, the documentation may become inadequate.

2. Common areas and shared circulation space

Common areas can be challenging because their use does not always correspond to a single tenant or a simple cost allocation key. The assessment must reflect actual use, leases and how costs are allocated.

3. Vacant premises

Vacant premises can affect VAT deductibility and documentation requirements. The key is to show status, intention and historical records. In other words, not just what the premises are today, but why they have been treated that way.

4. Allocation keys that take on a life of their own

Service charges, VAT and allocation keys are closely connected. If the allocation key does not reflect actual use, both the reconciliation and the VAT treatment can become harder to explain.

5. Documentation that cannot be traced

When someone asks about an assessment, knowing that it was once carried out is not enough. You need to show its basis, date, assessor and the assumptions that applied.
