Class 3 NICs: time limits for paying class 3 NICs: background
Class 3 NICs cannot be accepted if they are too late to count for benefit. The Class 3 is said to be precluded. If a contributor pays Class 3 NICs which are too late to count for benefit, the contributions may be refunded or appropriated to another year, see NIM25005.
Regulation 62, Social Security (Contributions) Regulations 2001
Class 3 NICs can also be paid by a third party on behalf of a deceased person
- if they were entitled to pay before the date of death, and
- if the payment would benefit the next of kin.
The same time limits and higher rate provisions apply.
