If your transfer tax return or your payment is overdue, the Tax Administration will impose penalty charges. In the same way, a penalty charge is also imposed for late filing of a request for registration of title.
Look up the deadlines for transfer tax return filing and payments.
The return is not submitted by its deadline date: Late fee or a punitive tax increase
If you file the transfer tax return late, you must pay a late-filing penalty or an increased tax. The amount you must pay depends on how many days the tax return is late.
You make an overdue payment: late-payment interest
If you do not pay your transfer tax on time, you must pay interest. In 2026, the interest rate is 9.5%.
It is your responsibility to add the interest, on your initiative, to the transfer tax that you are paying after its due date. If you pay in MyTax, the interest is included in the sum automatically. Use the late-payment calculator to work out the exact amount.
Another situation where you must pay interest is if you applied for registration of your title or lease in time but you paid the transfer tax late.

Registration request is submitted late: a punitive tax increase may be imposed
If you have not applied for the registration of your title to a house, a real estate unit or lease in time, you will have to pay an increase.
Transfer tax is increased by 20% for each six-month period that begins. The counting of time towards the six-month periods begins the next day when the deadline date for registration has passed. However, although you might be late by many six-month periods in a row, the transfer tax will only be increased up to a maximum of 100%.
Because the increase is legally imposed due to your lateness with registration, and is not related to your taxes, the increase must be paid even if you had filed and paid transfer tax on time.
This is how you need to report and pay the increase
You can take care of the filing and payment of the increase in MyTax.
