Don’t forget, if you do your own self assessment form and submit it online, you only have 10 days left to get it done.
Closing date for online self assessment is 31st January.
Don’t leave it until the 31st! In our experience, the closer you get to the 31st, the more trouble you have, as their system tries to cope with everyone doing theirs at the last minute. Get it done asap and avoid those fines.
