Key takeaways
  • Spousal support can be periodic or a lump sum, and a court can order either.
  • The Divorce Act and the Family Law Act each list what a court considers when setting support, including each person's condition, means, needs and other circumstances.
  • The wording of your order or agreement matters, and an agreement cannot change an existing support order.

If you pay or receive spousal support, one of the first questions is what it does to your tax return. People often assume the answer is the same for everyone. In practice it depends on the type of payment, how it is set out in your order or agreement, and your own situation.

This article explains the parts of Alberta spousal support that affect that question, so you know what to bring to an accountant. How tax applies to your payments depends on your year and facts, so it is worth confirming with an accountant or a lawyer.

This article covers the law of Alberta.

Support law and tax law are separate questions

Spousal support is set under one of two laws. For married couples seeking a divorce, the federal Divorce Act lets a court order one spouse to pay lump-sum or periodic support. For unmarried adult interdependent partners, and for married spouses who are not seeking a divorce, the Alberta Family Law Act applies.

Those laws deal with entitlement, amount and duration. Under the Divorce Act, for example, the court considers the condition, means, needs and other circumstances of each spouse. A support order is not the same thing as a tax ruling, so do not assume the order answers the tax question.

Why the type of payment matters

A court can order support as a lump sum or as periodic payments, and it can also make an interim order while the main application is waiting to be decided. An order can run for a definite or indefinite period, or until a specified event occurs, and can carry terms and conditions.

Each of these features can matter when you ask for tax advice. Describe exactly which kind of payment you have, whether lump sum, periodic or interim, when you ask for advice.

Your order or agreement is the starting document

Your accountant will want to see the exact wording of your court order or written agreement. Details such as who pays, how often, how the amount is described and whether child support is dealt with separately can all be relevant. When child support and spousal support are both claimed, the court gives priority to child support, so the two amounts should be clearly identified.

An agreement cannot be used to vary an existing spousal or partner support order. If you want to change how payments are structured after an order exists, the route is generally an application to vary, not a side arrangement. A court can vary, suspend or terminate support where there has been a change in circumstances.

Points to confirm before you file

If your order has been varied, keep the original and the varying order together. Variation can be retroactive or prospective under the Divorce Act, so the dates in the order can matter.

What to do next

Getting the order wording right at the start is far easier than fixing it later, so involve both a lawyer and an accountant when you are negotiating support.

Frequently asked questions

Is spousal support taxable in Alberta?

The answer depends on the type of payment and how your order or agreement is written, so it is worth confirming with an accountant. The support laws set out when support can be ordered and what a court considers. An accountant can confirm how your payments are treated.

Is a lump sum treated the same as monthly support?

How a lump sum compares with monthly support for tax depends on your situation, so it is worth confirming with an accountant. A court can order lump-sum or periodic support, so it helps to know which one applies to you. Ask an accountant before you agree to a structure.

Does the Maintenance Enforcement Program affect my taxes?

The program collects and enforces spousal and partner support payments unless the parties agree or the court orders otherwise. It is a collection service, so the tax question still depends on the order and your circumstances. Keep its payment records for your accountant.

Can we just change the payment arrangement ourselves?

Not if there is already a support order. An agreement cannot vary an existing spousal or partner support order. A change generally needs a court application based on a change in circumstances.
