Income / franchise tax return

3 dates · 1 not dated yet

The annual return for the business’s tax year, and in franchise-tax states the report that keeps the entity in good standing. Which form and which date depend on the entity type and the tax year. Where the source grants an extension, it extends the time to file; the source says whether it also extends the time to pay.

Why no dates: Every date shown here is checked against its official source.
