The two types of limited companies, 1931 and 2006, appear very similar but have key differences that may impact your business, depending on which you choose.

You must VAT register if:

At the end of any month, the total value of your taxable supplies you have made in the preceding 12 months (on a rolling 12-month basis) exceeds the VAT registration threshold, or
