The table below highlights some of the key dates to look out for when returning paperwork to HMRC. Chances are, your accountant will be well aware of all tax deadlines, however business owners are ultimately responsible for ensuring that tax liabilities are paid on time.
Some deadlines relating to VAT, annual company accounts (for limited companies), and your Annual Return (for limited companies), will be unique to your own business, so they are not listed listed here.
This table only includes annual deadlines. You can find out more about the deadlines for monthly/quarterly PAYE and NICs at the HMRC site.
You may have several extra days to pay your liabilities beyond the dates listed below if you pay electronically rather than via cheque.
