Alberta rules in brief
Justice Canada says every province and territory except Quebec has adopted the Federal Tables in its provincial child support laws. Alberta.ca lists how to apply for child support, change a court order, and use the Child Support Recalculation Program.
How the Alberta table amount is worked out
Schedule I lists income in $1,000 bands. For each band it gives a basic monthly amount plus a percentage of the income above the start of the band. The Guidelines give this example: for a payer with an income of $51,250 and two children in British Columbia, the row starting at $51,000 has a basic amount of $807 and 1.54%, so the monthly amount is $807 + 1.54% x $250 = $810.85.
What the table amount does not include
The table is the starting point under section 3. A court or agreement may add section 7 expenses (child care, health costs above insurance, extraordinary school and activity costs, post-secondary education), and the amount changes if parenting time is shared at 40% or more (section 9), split between parents (section 8), or undue hardship is shown (section 10). The tables cover incomes up to $150,000, and income of $16,000 or less produces a table amount of $0.
Which period these tables cover
These are the 2025 Federal Tables, in force on 1 October 2025. For support owed between 22 November 2017 and 30 September 2025, Justice Canada says to use the 2017 Tables. An order made before 1 October 2025 does not change automatically, though a different table amount could be a change in circumstances that allows a variation.

Frequently asked questions
Does Alberta use the federal tables?
Justice Canada says all provinces and territories except Quebec have adopted the Federal Tables in their own child support laws, so the Alberta amount is the Alberta row of Schedule I. Alberta.ca also lists a Child Support Recalculation Program and how to apply for or change child support.
How much is child support in Alberta for two children at $75,000?
The 2025 Alberta table amount for two children at $75,000 a year is $1,091.00 a month. That is the basic amount only; section 7 expenses and shared-parenting rules can change what is paid.
Which province's table do I use if the parents live in different provinces?
Justice Canada's guide says to use the table for the province where the paying parent lives when one parent has the majority of parenting time. If parenting time is shared or split, use both tables. Use the main table amount calculator to switch provinces.
What if the paying parent earns over $150,000?
The table has a $150,000-or-greater row with a basic amount plus a percentage of income above $150,000. Under section 4 a court may find that inappropriate and set the amount on the income above $150,000 itself.
Is this the same as the official calculator?
It uses the same Schedule I rows and formula. Justice Canada notes its own simplified tables round incomes to the nearest $100, so results can differ by a small amount; only the table in the regulation is the legal version.

Not legal advice
This is general information built from the published Federal Child Support Guidelines tables. It is not legal advice and it is not an official calculation. Only the table in the regulation is the legal version, and a court or agreement can set a different amount. Income for child support is defined by the Guidelines, not by your tax return alone. For an order or agreement, talk to a family lawyer, a family law information centre or your provincial family justice service.
