Information for Fiscal-Year Taxpayers
If you use a fiscal year (rather than the calendar year) as your tax year, you should change some of the dates in the general federal tax calendar. Use the following general guidelines to make these changes.
The 3 months that make up each quarter of a fiscal year may be different from those of each calendar quarter, depending on when the fiscal year begins. Also see Saturday, Sunday, or legal holiday, earlier.
