If you fail to file Form 7004 (tax extension) or your tax return by the applicable deadline, the IRS may charge interest and penalties on any unpaid federal taxes.
The deadline to file Form 7004 is the same as your original tax return due date — typically the 15th day of the 3rd month after the tax year ends for S corporations and partnerships, and the 15th day of the 4th month for C corporations. For businesses following the calendar year, this is usually March 15 (S corps/partnerships) and April 15 (C corporations), or the next business day if the date falls on a weekend or holiday.
