These dates may be adjusted if they fall on weekends or holidays, ensuring taxpayers have ample time to fulfill their obligations.

Exceptions and special considerations

Publication 509 also addresses exceptions and special considerations for certain dates. For example, the final quarterly payment is postponed until January to accommodate taxpayers during the busy holiday season in December. Residents of specific states may benefit from additional time to file taxes due to state holidays falling on the 15th of certain months.
