On 9 April 2020, the Finnish tax administration announced an extension of filing deadline for corporate tax returns by one month due to coronavirus outbreak. Corporate entities and benefits under joint administration whose accounting period ended between December 2019 and February 2020 can now file their tax returns within five months from the end of the accounting period (previously four months).
The new filing deadline will be displayed in MyTax in April. The decision concerns approximately 80% of corporate entities and benefits under joint administration. For most such corporate taxpayers, the accounting period ended on 31 December 2019. Normally, these taxpayers would have to file their tax return by 30 April 2020. However, this filing deadline has now been extended to 31 May 2020. Because the day is a Sunday, the tax return can still be filed on Monday 1 June 2020. Despite the extensions, the Tax Administration wishes that all companies and organisations who can file their tax return by the normal filing deadline would do so.
