VAT: the five most common errors in invoicing

Input tax deduction, flat rate tax method, and foreign services — what the FTA particularly focuses on during audits.

Nadine Brunner · Head of VAT · 6 Min. Reading Time

The Classics

Most corrections during audits do not arise from intent, but from routine. Recurring bookings are adopted without anyone re-evaluating the facts.

– Input tax deduction on vehicles and real estate used privately.

– Acquisition tax on services from abroad is forgotten.

– Flat rate VAT remains the same, although the activity has changed.

– Discounts and credits are not clearly separated.

– Missing documentation for export deliveries.

How to prevent it

A brief annual reconciliation between accounting and settlement is sufficient in most cases. It is important that documents are digitally retrievable — during an audit, provability, not good intention, is decisive.

The most important points in brief

– Perform a sales reconciliation once a year.

– Check acquisition tax for every purchase from abroad.

– Archive export documentation digitally for five years.
