NIM37002 - Refunds: Class 1: Minimum refund level

Regulation 52(1) of the Social Security (Contributions) Regulations 2001 (SSCR 2001) (SI 2001 No 1004)

Class 1 NICs paid in error or in excess of the annual maximum will only be refunded if the amount involved is not less than one fifteenth of a Class 1 contribution at the main primary percentage payable on earnings at the weekly UEL for the last, or only, tax year for which the NICs were paid. 

It is calculated using the formula  ((UEL바카라 사이트“PT) x main primary %) ÷ 15 

For example, for the 2025바카라 사이트¯to 2026바카라 사이트¯tax year the following rates and thresholds apply 

Weekly UEL = £967 

Weekly PT = £242 

Main Primary percentage rate = 8% 

(967 - 242) x 8%)바카라 사이트¯Ã· 15 = £3.86

Below this amount HMRC is not required by law to make the refund (regulation 52(5) SSCR 2001). 

Small refund level 

There is a level below which an excess refund will not be automatically refunded but is available only if the contributor asks for it. HMRC sets this 바카라 사이트˜small refund level바카라 사이트™ at half the current year바카라 사이트™s weekly LEL. 

For example, for the 2025 to 2026 tax year the small refund level is (£125 ÷ 2 = £62.50)Â
