- Second payment on account for {taxYear}: 50% of the previous year's bill.
How to be ready
No return is due in July, only money: the second half of the advance HMRC sized from your last bill. If this year is tracking lower, you can apply to reduce it before paying; reduce below the real outcome, though, and interest applies on the gap.
If you miss it
A day late already costs 100 in fixed penalty for the return; three months late adds 10 a day. Late PAYMENT runs separately: interest from day one and a 5% surcharge at 30 days. If cash is the problem, file anyway and ask HMRC for a Time to Pay plan; the filing penalty is the avoidable one.
