Definition
A Registered Disability Savings Plan (RDSP) is a savings plan for Canadians eligible for the Disability Tax Credit (DTC). The federal government matches contributions through the Canada Disability Savings Grant (CDSG) and provides the Canada Disability Savings Bond (CDSB) without any contribution required. The CDSG matches 300% on the first $500 and 200% on the next $1,000 of annual contributions for families with net income below approximately $106,717 (2026 threshold, indexed), and 100% on the first $1,000 for higher-income families. The lifetime CDSG maximum is $70,000. The CDSB pays up to $1,000 per year (lifetime maximum $20,000) into the RDSP of low-income plan holders with no contribution required. Grants and bonds are subject to a 10-year repayment (holdback) rule: if the RDSP is closed or certain specified triggering events occur within 10 years of any government payment, those grants and bonds must be repaid.
