Extended 2025 Returns Due
Final deadline for returns with approved extensions. No further extensions available.
Tax deadlines are adjusted when they fall on weekends or federal holidays. If a deadline falls on a Saturday, it moves to the following Monday. If it falls on Sunday, it also moves to Monday.
Estimated tax payments are required if you expect to owe $1,000 or more when you file your return. This typically applies to self-employed individuals, freelancers, and those with significant investment income.
Extensions give you more time to file, but not more time to pay. Interest and penalties may apply to taxes owed after the original due date.
