Nearly every adult in the U.S. must file an annual federal income tax return with the IRS that discloses their income, identifies tax deductions and credits, and states the amount of tax that is owed. What happens if a taxpayer fails to file on time? The consequences could include penalties and interest, as well as limits on the ability to obtain relief if they cannot afford to pay their tax bill.
What Are the Tax Deadlines?
Federal income tax returns are due on April 15 of each year. If the 15th falls on a Saturday, Sunday, or federal holiday, the due date is the next business day. California has the same deadline for state income tax returns.
Taxpayers may be able to obtain an extension of up to six months to file their federal tax return. This typically requires filing an extension form, and paying their estimated tax owed, prior to the April deadline.
