Hi, I will be making a payment to HMRC for backdated years.
For years 2019 onwards where the 'Final Time Limit' say is April 2026, or April 2027, I was going to wait and pay those years each year.
However, I see in my letter it days Contribution amount 'It can increase if we do not receive your payment by the 'Payment Date without Penalty'
the Payment Date without Penalty is April 2025 up to and including last year 2024.
What might those penalities be does anyone know?
