The tax filing and payment deadline has been extended to 3 November 2025 for Missouri taxpayers.
The US Internal Revenue Service (IRS) issued MO-2025-01 on 25 June 2025, announcing tax relief for individuals and businesses in parts of Missouri affected by severe storms, straight-line winds, tornadoes, and flooding that began on 16 May 2025.
These taxpayers now have until 3 November 2025 to file various federal individual and business tax returns and make tax payments.
Following the disaster declaration issued by the Federal Emergency Management Agency (FEMA), individuals and households that reside in or have a business in the City of St. Louis and in Scott and St. Louis counties qualify for tax relief.
As a result, affected individuals and businesses will have until 3 November 2025 to file returns and pay any taxes that were originally due during this period.
The 3 November deadline also applies to 2024 contributions to IRAs and health savings accounts for eligible taxpayers. This relief also applies to the estimated tax payments normally due on 16 June and 15 September 2025.
Penalties on payroll and excise tax deposits due on or after 16 May 2025, and before 2 June 2025, will be abated as long as the tax deposits were made by 2 June 2025. In addition, the 3 November deadline also applies to affected businesses extending the quarterly payroll and excise tax returns normally due on 31 July and 31 October 2025.
If an affected taxpayer receives a late filing or late payment penalty notice from the IRS that has an original filing, payment or deposit due date that falls within the postponement period, the taxpayer should call the telephone number on the notice to have the IRS abate the penalty.
The IRS automatically identifies taxpayers located in the covered disaster area and applies filing and payment relief.
