Tax return basics

The tax return reports income and deductions to the tax office. The tax office sets the tax in a notice.

In more detail

ELSTER is the tax administration's electronic portal. Under Income Tax Act section 25 (4), electronic filing is required mainly for people with business or self-employed profits. Someone with only employment income may still file on paper. The filing deadline is in section 149 of the Fiscal Code and can be longer when an adviser is instructed. Finmon names no calendar date, because deadlines change and can move in a particular case. The tax office says what applies.

Background

A return is not advice and not automatic money back. It can produce a refund or an extra payment, depending on what was already withheld in the year and which income is added. Finmon fills in no form and stores no tax data.

An example

Wage tax was withheld in the year, and there are work expenses above the flat amount. Whether that leads to a refund is calculated by the tax office in the notice. The return is the way to put those facts on the table. Finmon does not file it.

A common misconception

A tax return always brings money back.

It can produce a refund or an extra payment. That depends on withholding and income, not on the form alone.
