Coverage · 2 of 6 fully dated
Income / franchise tax return
UnsupportedThe 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: No official source confirmed yet for Wyoming's business income or franchise tax return due dates.
