Preparing your VAT return: a checklist per quarter
For most business owners the VAT return comes around every quarter, and yet it often feels like a surprise noticed just too late. That is rarely down to the return itself, but to preparation work left sitting until the final days before the deadline. This article offers a checklist to spread that preparation across the quarter, plus the mistakes that come up most often.
Why is preparing per quarter better than doing everything right before the deadline?
Adding up three months of invoices and receipts into a VAT return in the last week before the deadline is not only stressful, it is also more error-prone. Rushed work makes you more likely to miss an invoice, book an amount in the wrong box, or forget a deduction.
Anyone who keeps the books weekly or monthly instead of once a quarter also spots problems sooner, such as a customer who never paid an invoice or a lost purchase receipt. Waiting three months makes a problem like that harder to fix than noticing it after a week.
Preparing regularly also means the actual return becomes a matter of checking and filing, instead of catching up on three months of work first. Once the habit sticks, a quarterly return stops feeling like a separate project and becomes a small recurring moment within the normal rhythm of the books.
What exactly do you need for a complete VAT return?
To start: all sales invoices for the quarter, complete and with the correct VAT rate per line. An invoice still sitting as a draft in your system does not count, so check that everything was actually sent and did not get stuck.
Also all purchase invoices and receipts for which you want to reclaim VAT (input tax), including receipts for smaller costs that are easy to forget, such as parking fees or fuel on the way to a job.
Finally: an overview of any corrections, such as a credit invoice for a cancelled job, or special situations like the VAT reverse charge for a customer abroad. These items get forgotten often because they are not part of the standard flow of invoices, which is exactly why it pays to note them separately as they happen instead of trusting yourself to remember them at the end of the quarter.
Which mistakes come back every quarter?
The most common mistake is an invoice accidentally landing in the wrong quarter, for example because the invoice date and the actual delivery date do not match. When in doubt, check which date leads for the VAT return.
A second common mistake is double-counting or entirely skipping input tax, especially for receipts used both for business and personally. Split these clearly before entering them into the books, instead of having to work out afterwards which part was business.
A third mistake: forgetting that the small business scheme (a VAT exemption for a low annual turnover, known as the KOR) brings different rules than the standard VAT return. Anyone on the KOR who still puts VAT on an invoice has to correct that before filing.
How does bookkeeping software reduce the preparation work?
Software that already tracks sales and purchase invoices throughout the quarter does not need to gather everything at the end: the figures are already there, sorted by box according to the VAT rules.
A system that warns about an incomplete invoice or a missing VAT number stops a mistake from only surfacing at the return itself, when correcting it costs more time than getting it right in the first place.
TelMaar builds up the VAT boxes continuously from the ongoing books, so the quarterly return becomes a matter of checking what is already ready, instead of processing three months of documents at once.
Checklist: what to do and when during the quarter?
Weekly: send out open quotes and invoices, and process incoming purchase invoices and receipts right away instead of letting them pile up in a drawer or inbox.
Monthly: check that all sales invoices for that month were actually sent, and did not stay as a draft. Also check for special items, such as a credit invoice or a purchase from abroad.
In the last week before the deadline: go through the VAT boxes calmly one more time instead of compiling them for the first time, file the return, and keep the supporting records as legally required. Then set a reminder for next quarter right away, so preparation starts on time again instead of only when the next deadline is already in sight.
Frequently asked questions
How often should I update my books for the VAT return?
Updating weekly or monthly prevents you from catching up on three months of work in the final days before the deadline, and surfaces mistakes sooner than at the return itself.
Does a draft invoice count toward the VAT return?
No, only invoices that were actually sent count. Before filing, always check whether any invoices stayed as a draft when they should have been sent.
What if I discover a mistake after the return has already been filed?
