Just a reminder 👇
If you were due to make a Self Assessment Payment on Account by 31 July and still haven't paid it, HMRC will now be charging late payment interest on the outstanding amount until it's cleared.
A lot of people don't realise that even if no late payment penalty has been issued, interest starts accruing from the day after the deadline.
If you're unsure whether you had a payment due, it's worth checking your HMRC online account sooner rather than later.
💡 The longer it's left unpaid, the more interest builds up.
