Tax returns must be shared during divorce as part of mandatory financial disclosure requirements

In Canadian divorce proceedings, sharing tax returns with your ex-spouse is a legal requirement under financial disclosure obligations. These documents are essential for:

• Calculating accurate child support payments based on income
• Determining appropriate spousal support amounts
• Ensuring fair division of matrimonial assets and debts
• Verifying income sources and financial status for both parties

Typically, you’ll need to provide tax returns for the past three years, along with supporting documents like T4s and notices of assessment. Failing to disclose tax information can result in legal consequences and delay your divorce proceedings.
