Class 1B NICs are payable on

• items within a PSA that ordinarily attract a Class 1 PSA3040 or Class 1A NICs liability, PSA3030

Class 1B NICs replace any Class 1 or Class 1A NICs liability attached to the benefits and expenses included in a PSA for tax purposes

Only items that attract a tax charge can be included in a PSA. You cannot use a PSA

• where there is NICs only liability, or
• to cover elements which have NICs only liability
