Tick what applies to you and you will see only your deadlines – VAT return and control statement, income tax advances, contributions for yourself and for employees, and motor vehicle tax. Deadlines that fall on a weekend or holiday are already moved to a working day. With one tap you save each deadline to your phone calendar, with a reminder in advance.
The calendar is built instantly. Your browser remembers your selection and the checked-off deadlines, so when you come back next month, you will see right away what still needs to be done.
We calculate deadlines according to the laws in force as of 11 October 2026 and move them to the next working day. They may differ for a fiscal year, a different setting of advances by the tax administrator, or a quarterly EC Sales List.
A penalty for a late VAT return or control statement is often higher than the tax itself. Download your deadlines for the whole year to the calendar on your phone or computer – each with an alarm that rings at 9:00 in advance. Works on iPhone, Android, Outlook and Google Calendar.
Each square is a day with an obligation – point at it and see what needs to be done that day. You can see at once when it gets busy: at the end of January, March and April, returns, motor vehicle tax and annual reconciliation all meet.
If a deadline falls on a Saturday, Sunday or public holiday, the last day is the next following working day.

The working time fund is the number of working days in a month times the daily working time: for a 40-hour week 8 hours, for 38.75 hours 7.75 hours and for 37.5 hours 7.5 hours a day. A public holiday falling on a working day reduces the fund, but an employee on a monthly salary does not have their pay cut – that is why for each month we also show the hours including holidays. In 2026, 8 May and 15 September are not non-working days, and since 2025 neither are 1 September and 17 November. The fund applies to evenly distributed working time.
The VAT return and the VAT control statement are filed electronically within 25 days after the end of the tax period, and the tax is due by the same deadline. So a monthly payer files by the 25th of every month, a quarterly payer by 25 January, April, July and October.
Contributions to the Social Insurance Agency and the health insurance advance for employees are due on the day you have set for paying wages – not on the 8th, as is often stated. Payroll tax advances are paid no later than 5 days after payday. That is why you set your payday in the calendar.
A self-employed person pays contributions to the Social Insurance Agency and the health insurance advance by the 8th day of the month following the month they relate to. For October that means by 8 November – and if that is a weekend, by the next working day.
If your last known tax was higher than €5,000 and at most €16,600, you pay quarterly advances by the end of each quarter. Above €16,600 you pay monthly by the end of each month. This applies to sole traders and companies alike, unless the tax administrator decided otherwise.
The return is filed and the tax paid by 31 January 2027. As that is a Sunday, the last day is Monday, 1 February 2027. If the expected tax exceeds €700, you pay quarterly advances during the year, and above €8,300 monthly advances – always by the end of the quarter or month.
2026 has 254 working days, which gives a working time fund of 2,032 hours at a 40-hour week; 7 public holidays fall on a working day. 2027 has 253 working days and a fund of 2,024 hours, with 8 holidays on a working day. You will find the breakdown by month, also for 38.75 and 37.5 hours per week, above.
The deadline moves to the next following working day. The calendar does this for you and marks the moved deadline. It also accounts for changes to public holidays – 1 September and 17 November are no longer non-working days, and in 2026 neither are 8 May and 15 September.
No. The calendar runs entirely in your browser and your selection is remembered only by this browser. Nothing is sent to our server – no name, email or settings. The calendar file is created directly on your device.
We will file VAT, the control statement, payroll and contributions on time – and you only get a message saying how much to pay and when.
