Taiwan’s Ministry of Finance has announced that income tax returns for the 2025 tax year can be filed from 1 May 2026, with e-filing remaining available despite the public holiday closure of tax offices on the opening day.
Taiwan’s Ministry of Finance has released a notice, on 21 April 2026, setting out the income tax return filing period for the 2025 tax year.
The Ministry of Finance states that the filing period will begin on 1 May 2026. As that day is a national holiday, tax offices will be closed to the public while the e-filing system will remain available.
The Ministry of Finance encourages taxpayers to file their income tax returns online. In addition, the statutory filing deadline, 31 May, falls on Sunday and is therefore extended to 1 June.
