Alimony payments have tax implications for both partners.
When the end of matrimony leads to the start of alimony, each ex has a new tax-related task. If you're the ex-spouse getting alimony, the money is taxable to you as income.
No taxes are withheld from alimony, so you may need to make estimated tax payments on a quarterly basis.
The alternative is to increase the amount withheld from your paycheck. And your option to file shorter, simpler tax forms disappeared with the first alimony check you cashed. The money must be reported on line 11 of the long Form 1040.
What if you're the ex making the payments? You get a tax break. You may complain every month when writing the check, but you now can claim a new tax deduction. Subtract your alimony payments from your income on line 31 of Form 1040. While you may be out some money, at least you get to pay less in taxes.
