2025 update to the Federal Child Support Tables

The Federal Child Support Tables (Federal Tables) set out the basic monthly amounts of child support under the Federal Child Support Guidelines. The Federal Tables have been updated to reflect more recent tax rules. The updated Federal Tables came into effect on October 1, 2025. To calculate child support for a period before that date, please see the note below for the links to previous Tables.

The official legal version of the 2025 Federal Child Support Tables can be accessed here.

Tools to help calculate child support amounts include:

While you may find the simplified tables and the look-up tool easier to use than the official Federal Tables, only the official Federal Tables version is a legal document. The simplified tables and the look-up tool are public legal and information tools intended to provide general information.

The results you get using the simplified tables may not be exactly the same as the results you get using the look-up tool or the official Federal Tables. That is because child support amounts in the simplified tables are based on incomes rounded to the nearest $100. However, the results will be very close.

Before you use the tables, you may find it helpful to consult our Federal Child Support Guidelines: Step-by-Step guide. This guide provides 8 easy steps to help you determine child support under the Federal Guidelines.

Note

  • To determine how much child support is owed for a period between November 22, 2017 and September 30, 2025, use the 2017 Federal Tables to find that amount. Use the updated 2025 Federal Tables to determine child support owed from October 1, 2025 onward.
  • To calculate child support for a period of time before November 22, 2017, use previous Federal Tables. Links to the 2017, 2011 and 2006 Tables are below.
  • The new 2025 Federal Tables will not automatically apply to a child support order made before October 1, 2025. However, if the updated child support amount is different from the amount in your current order, it could be considered a “change in circumstances.” You could ask a court or a recalculation service to have your child support amount updated using the new 2025 Federal Table amounts.
