When preparing to file your federal tax return, don’t forget your contributions to charitable organizations. Your donations could add up to a sizeable tax deduction if you itemize on IRS Form 1040, Schedule A.

Here are a few tips to ensure your contributions pay off on your tax return:

1. Contributions must be made to qualified organizations to be deductible. You cannot deduct contributions made to specific individuals, political organizations and candidates.

2. You cannot deduct the value of your time or services. Nor can you deduct the cost of raffles, bingo or other games of chance.
