What is my business required to do?
Lets simplify things -
the tax year starts 6 april and ends 5 april, and you’ll need to do an income tax return. the online return is due the 31 january after the end of the tax year.
if you’re self-employed then you’ll need to register with hmrc to make sure you’re paying the right tax.
you’ll need to keep records, and at the end of the year you’ll need to calculate your taxable profit for your income tax return. its likely you’ll need to pay class 2 and class 4 national insurance contributions (nic).
your income tax is paid in two payments, 31 january and 31 july.
