Tax and VAT returns are necessities. You are usually required to send a VAT return every three months and tax is an annual requirement. JJO Accountancy in London can take care of it all for you.

Whether or not your company makes a loss or if you have no Corporation Tax to pay, you are still legally required to deliver a Company Tax Return, which includes Corporation Tax profit or loss and a Corporation Tax bill.

If you miss the deadline, you’ll be obliged to pay a penalty, so let us help you get your records ready and get your Company Tax Return delivered on time. We’ll also help you with your Corporation Tax bill.

If you’re a sole trader, you won’t need to send in a Company Tax Return. However, we can still assist you with your Self Assessment Return.
