The general deadline to file a tax return is July 31 of the year following the tax year. For example, the tax return for the year 2024 must be filed by July 31, 2025. If a tax advisor or tax assistance association is involved, the deadline may be extended, usually until the end of the following year or later. Voluntary tax returns can be filed retroactively for up to four years. Missing the deadline can lead to penalties or late fees, so it's important to file on time or request an extension if needed. These rules apply primarily in Germany, reflecting typical deadlines for mandatory filing without professional tax advice.
For individual taxpayers dealing with the IRS in the United States, the typical deadline to file individual taxes is April 15 of the year following the tax year, with an extension available until October 15 if requested.
