What are tax installments?

Installments are advance payments toward your annual income tax. CRA uses them to reduce large year-end balances and smooth payment timing over the year. Self-employed people often see them, but they can also apply to other situations with recurring tax owing.

If CRA expects installments, they typically send a notice. Always check your CRA notice for official expectations.

When you might see them

Installments often relate to prior-year balances. If your net self-employment income has been growing or you usually owe at tax time, your risk can be higher. Even without a notice, many people plan a buffer to avoid surprises.

This is a planning concept only. CRA rules vary and your notice is the best source of truth.

How installment schedules usually work

CRA often uses quarterly due dates for installment planning, but dates can vary by year. Use the CRA important dates page for the current schedule.
