We send the tax assessment notices as soon as they’re ready. Everyone will receive their tax assessment notice before 1 December.
Unfortunately, we cannot give you a specific date for when you’ll receive your tax assessment notice. You’ll be notified when it’s ready.
If you have underpaid tax, you’ll receive an invoice with payment information well before the due date. You can also choose to pay all or part of the underpaid tax before you get the invoice. Log in to My page to see an overview of your claims and payments and to find payment information.
If you’ve underpaid tax, this is usually because not enough tax has been deducted during the year. Avoid underpaying your tax next year by checking the numbers in your tax deduction card for 2024. You must change your tax deduction card if the numbers are incorrect.
If you’ve received the tax return for businesses, you must submit it. Even if you’ve terminated your business activity or have had no revenue, you must still submit.
If you have not submitted within the deadline, you must submit your tax return as soon as possible.
