State & Federal Deadlines
Deadlines and requirements vary by state. That's why we've developed an easy tool to determine your filing requirements. Use the Deadline Calculator below to select your state and form type and we'll tell you the federal, state and recipient deadline for the current reporting year. We've also included the number of parts you'll need to help you plan when ordering forms, envelopes and stamps.
Note: We recommend you submit your forms for filing 48 hours before the deadline to ensure processing time and timely filing to state agencies.
If the due date falls on a weekend or holiday, the due date is the next business day.
Please select State and Form Type using the dropdowns below.
