Filing frequencies are assigned based on what you estimate for your yearly business income.

Due dates

Monthly returns are due the 25th of every month. (e.g. The June tax return is due July 25.)
Quarterly returns are due the end of the month following the tax quarter. (e.g. The Quarter 1 (Jan, Feb, Mar) tax return is due April 30.)
Annual returns are due April 15. (e.g. The Annual 2019 tax return is due April 15, 2020)

If the due date falls on a weekend or legal holiday, the due date is extended to the next business day.
