FAQ
What happens if my tax deadline falls on a weekend?
The IRS and most states move the due date to the next business day when a deadline lands on a weekend or holiday.
Does an extension give me more time to pay?
Extensions typically give you more time to file, not more time to pay. Any tax owed is still due by the original deadline.
Are state deadlines always the same as federal?
Many states conform to federal due dates, but some states set different deadlines or extensions, so always verify with the state tax agency.
