CRYPTO42200 - Cryptoassets for businesses: Income Tax: National Insurance contributions

Where cryptoassets are provided in the form of a readily convertible asset, HMRC also considers this to be earnings for National Insurance contribution purposes under Section 3 of the Social Security Contributions and Benefits Act 1992. The employer must therefore account to HMRC for the appropriate amount of Primary and Secondary Class 1 contributions via PAYE/Real Time Information for the relevant earnings period.
