Why directors should map personal and company tax deadlines separately.
Directors often assume their personal Self Assessment and their company's CT600 share a deadline. They don't.
Personal returns follow the tax year, while Corporation Tax payment and filing dates follow the company's own accounting period.
Mapping each deadline separately, and putting them in the diary, is the simplest way to avoid penalties.
