If you have not already submitted your tax return, you have just under two months to go.
The sooner you take your books and records to your accountant the sooner it can be booked in and completed. Ensure your records are complete with all sales/ purchase invoices, bank statements for all bank accounts, stock figures, finance agreements etc are included.
If you leave it too late, you will have less time to budget for any “unexpected” tax liability and you will also run the risk your return will not be completed on time.
Don’t forget HMRC charge a £100 penalty to individuals who did not submit their return before 31 January 2019, if you are in a partnership that could mean £300 in penalties!!
