Child Support Recalculation Program

Register Now! The Alberta Child Support Recalculation Program increases access to justice by providing many parents with a way to change their child support orders with ease, transparency and decreased cost.

The Recalculation Program (RP) is an administrative service that annually recalculates court-ordered child support based on current income tax information. Our goal is to help parents keep child support levels in line with income so families can avoid the time and expense of asking the courts to review their child support orders.

Parents must already have a valid court order (or binding agreement) for child support before they can be registered with RP. Not all court orders are eligible for registration with RP. If the child support order is eligible, RP can recalculate both table (monthly) amounts of child support and proportionate shares of special or extraordinary expenses.

RP's General Information Sheet provides a summary of their service.

New Child Support Guideline Tables

The Canadian government has updated the tables in the Federal Child Support Guidelines. The new tables come into force on November 22, 2017. For more information, visit the Important changes & news section of this site.

Recalculation Info Online (RIO)

RP's Internet client account system, RIO (Recalculation Info Online), offers RP clients convenient Internet access to their file information, 24 hours a day, seven days a week. Clients can both see and provide key file information in a secure way. RIO helps clients meet their legal obligations to update their contact details and provide income information each year.
