Essential Tax Deadlines: Your April 15th Reminder

Mark Your Calendar for April 15

By April 15, 2026, Long Island taxpayers must file their 2025 individual returns or request an extension. Remember, an extension grants additional time to file, not to pay owed balances. Midnight is the strict cutoff to avoid penalties and interest.
