Line 30300 - Spouse or common-law partner amount
Line 30300 - Spouse or common-law partner amount
You can claim this amount if, at any time in the year, you supported your spouse or common law partner and their net income from line 23600 of their return (or the amount it would be if they filed a return) was less than your basic personal amount (plus $2,687 if your spouse or commonlaw partner was dependent on you because of a mental or physical infirmity).
If you had to make support payments to your current or former spouse or common-law partner and you were separated for only part of 2025 because of a breakdown in your relationship, you can claim whichever amount is better for you:
-
the amount on line 22000 of your return for deductible support payments made in the year to your current or former spouse or common-law partner
-
the amount on line 30300 of your return for your spouse or common-law partner
If you reconciled with your spouse or common-law partner and were living together on December 31, 2025, you can claim an amount on line 30300 of your return and any allowable amounts on line 32600 of your return.
Only one spouse or common-law partner can claim the amount on line 30300 for each other for the same year.
You can claim the corresponding provincial or territorial non-refundable tax credit that you are entitled to on line 58120 of your provincial or territorial Form 428.
Special rules apply to claims for this amount if you were bankrupt during the tax year or if you immigrate to or emigrate from Canada in the tax year. For information about these rules, contact the CRA.
If you cannot claim the amount on line 30300 (or you have to reduce your claim) because of dividends your spouse or common-law partner received from taxable Canadian corporations, you may be able to reduce your tax if you report all of your spouse's or common-law partner's dividends. For more information, see line 12000 on page 14.
Net income of spouse or common-law partner
The net income of your spouse or common-law partner is the amount that they enter on line 23600 of their return (or the amount that it would be if they filed a return).
If you were living with your spouse or common-law partner on December 31, 2025, use their net income for the whole year even if any of the following applied:
-
You separated for part of the year and then reconciled and started living together again in 2025
-
You got married in 2025
-
You became a common-law partner or started to live with your common-law partner again in 2025 For more information, see "Marital status" on page 8.
If you separated in 2025 because of a breakdown in your relationship for a period of at least 90 days that includes December 31, 2025, and were still not back together at the end of 2025, reduce your claim by the amount of your spouse's or common-law partner's net world income before the separation.
