A fiscal year is 12 consecutive months ending on the last day of any month other than December.
Entities operating on a fiscal year must file their tax return on tax forms for the year in which the fiscal year begins.
For example, if an entity’s fiscal year begins November 1, 2018 and ends October 31, 2019, you should prepare the 2018 return using the 2018 Keystone Tax Solutions Pro program.
