T1206: Tax on Split Income

Important: While previously tax on split income only applied to individuals who were under the age of 18, all Canadian taxpayers will now be subject to this tax on certain types of income received during the year.

You’ll need to complete the T1206: Tax on split income form if you:

  • Were a Canadian resident at the end of 2023 (or were a Canadian resident immediately before your death), have split income in the tax year, and that income is not an excluded amount
  • Claimed a reserve on line C of your 2022 T1206 form

Note: If you were under 18 years of age at the end of 2023, at least one of your parents must have also been a resident of Canada at any time in the year.

Split income is treated differently and is subject to a special tax of 33%. However, it also qualifies for a deduction. Based on the information you enter on the T1206 page in H&R Block’s 2023 tax software, the software will automatically calculate your deduction amount.

Note: Certain federal, provincial, and territorial amounts are calculated using your income. If you had split income during the year, in order to calculate these amounts correctly, the deduction amount you’re claiming for split income has to be added back to your income, which might result in lower credit or deduction amounts. Some of the affected federal, provincial, and territorial amounts include the Spouse or common-law partner amount, Canada workers benefit (CWB), Amount for an eligible dependant, Canada caregiver amounts, Low-income tax reduction, and the Sales tax credit.
