VAT Filing and the Accountant's Role in Digital VAT

Published 12. april 2026

VAT is one of the most technical and error-prone areas in Danish business finance. For the individual business owner, the rules are often impenetrable, and the consequences of errors are serious. The accountant is a crucial gatekeeper — ensuring the VAT return is correct, timely, and legally compliant. With digital VAT, this role transforms from reactive to proactive.

The most common VAT errors in Danish SMBs

Wrong VAT code — the most frequent error, where an invoice is booked with incorrect VAT treatment. Missing reverse charge on EU purchases. Wrong periodization — VAT belongs in the invoice period, not the payment period. Representation vs. advertising confusion with different deduction rules. Small assets and depreciation threshold errors affecting both VAT and tax depreciation.

Digital VAT review: step by step

Step 1: Automatic reconciliation — compares booked VAT with filed returns. Step 2: VAT code check — scans all entries for code/account mismatches. Step 3: Reverse charge check — verifies foreign purchases. Step 4: Period check — ensures correct VAT period allocation. Step 5: Exception review — the accountant reviews only flagged entries. Step 6: Approval with digital signature and timestamp.

Multi-client VAT monitoring

Sitenyx's multi-client dashboard shows upcoming VAT deadlines with countdown, reconciliation status per client (green/yellow/red), and total VAT payable across the portfolio. Accountants can prioritize effort on clients with problems.

SKAT audit: documentation as insurance

With Sitenyx, the accountant has a complete digital audit trail for any VAT period: which entries were reviewed, when, by whom, and with what result. This documentation can be shown directly to SKAT, demonstrating systematic professional VAT review and significantly reducing the risk of estimated assessment.

How much time does digital VAT review save?

With Sitenyx, a complete VAT review takes 15-30 minutes per client instead of the traditional 2-4 hours. For a firm with 50 quarterly clients, that is 175-350 hours saved per year.

Can Sitenyx file the VAT return automatically?

Sitenyx prepares the VAT return and identifies errors, but the actual filing to SKAT is done by the client or accountant. This ensures human review before submission.

What if the client's bookkeeping has fundamental errors?

Sitenyx flags these errors during the automated review. The accountant can then work with the client to correct the bookkeeping before the VAT return is filed. This is far better than discovering errors months later during year-end.
