Check with your accountant: the calendar follows the general deadlines from the law, not your rulings and exemptions.
What is in the calendar and what is not
The calendar holds only the general deadlines from the law, with the name of the regulation next to each. It does not hold obligations that depend on your case: corporate income tax and the tax balance, the annual return of an entrepreneur keeping books, wage tax, property tax, local fees and deadlines from individual rulings.
Check with your accountant. Laws and deadlines change, and when a deadline falls on a non-working day, ask whether it moves. The calendar is a reminder, not tax advice.
This Tezga does on its own
The accountant report arrives before the deadline
Tezga sends the accountant a turnover and VAT overview after the period ends on its own, so the data for the return arrives on time, without copying from the register.
