If you are a company registered for VAT, you are obliged to file three key forms on a monthly basis:
- IOPPD — payroll form (taxes and contributions on salaries)
- OPP-ND — form for calculating local tax (municipal surtax)
- VAT return — form for calculating VAT
These are among the most important operational duties of your accountant on a monthly basis.
How to check timeliness — Tax Administration analytical card
You can check timeliness by obtaining the Tax Administration analytical card for your company — through your token.
Scenarios on the card
- Balance of EUR 0.00 for personal income tax and social contributions, with all IOPPD monthly forms recorded as due → the accountant calculates on time and you pay the liabilities regularly
- Prepayment on the card → you paid more than required
- Liability on the card → either not all forms have been recorded, or the calculation is not aligned with the payout, or payroll liabilities have not been settled at all
VAT and municipal surtax
On the VAT analytical card you can:
- Check VAT return charges by month
- Compare the VAT balance at the Tax Administration with the balance sent to you by your accountant
From the municipality where you are registered, you can obtain an analytical card of the surtax calculation — to check whether all OPP-ND forms have been filed and paid.
Why timely filing matters
Filing these forms is very important. If you do not file forms regularly, you can expect:
- Tax inspection
- Account freeze
- Fines and penalties
Also, if you apply for a tender, part of the mandatory documentation is a certificate from the Tax Administration confirming that all taxes and contributions have been settled. You certainly will not get it if not all forms have been filed and if the card balance is not EUR 0.00.
