How an Attachment of Earnings deduction is calculated

The court uses fixed tables based on your net earnings — the deduction isn't arbitrary.

Attachment of Earnings3 min readReviewed July 2026

The court works from statutory tables that set a protected earnings rate. Amounts above that rate are deducted at a set percentage until the debt is cleared.

You must complete form N56 accurately — omitting income can lead to a higher deduction; including all essential outgoings helps set a fair protected rate.

If your income changes significantly, you can apply to vary the order.
