+Apply the Pension Credit earnings disregards of SPC Regs 2002 Schedule VI: 20 pounds a week for lone parents, carers and claimants or partners on a listed disability benefit (including working tax credit with a disability element) or certified blind, otherwise 5 pounds (single) or 10 pounds (couple), capped at net earnings. Employed earnings are net of the income tax they add; self-employed earnings, in Pension Credit income too, are net of the notional tax and contributions of the Computation of Earnings Regulations 1996 reg. 14. The Housing Benefit savings-credit-only route now deducts only the higher Housing Benefit disregards.
