Detailed Explanation

## The deadline

The company income tax return is due 9 months after the accounting year end. For a company with a December year end, that is 30 September of the following year. Year ends between 1 January and 30 June all fall due on 31 March of the following year.

## Extensions

MTCA grants annual electronic-filing extensions of roughly 1 to 2 months. They apply to e-filing only, so the tax payment deadline does not move.

## Late returns

Late returns attract additional tax from €50 up to €1,500 for companies, scaling with the delay. Late tax bears interest of 0.6% per month, capped at 100% of the tax.

## Provisional tax first

Provisional tax is paid during the year in three instalments. The return settles the final position against those payments.

## What Finn does

Finn tracks the return date and the three instalments, and prepares the computation at 35% with the refund position or at 15% where the election has been made. You file through MTCA e-services.
