Thanks for choosing TurboTax. Yes, you can claim spousal support as a deduction. Spousal support (commonly referred to as alimony) is considered fully taxable in the hands of the recipient. And it is deductible from the income of the payee.
The former spouse or common-law partner must claim spousal support as taxable income if the court order or written agreements clearly spells out the amount to be paid on a recurring basis (often monthly) and there are no outstanding child support payments. In this case, the individual making the support payments can claim a tax deduction on the tax return for support payments made.
