Do Donations Affect Adjusted Gross Income?

by Ashley Adams-Mott ; Updated July 27, 2017

The IRS defines your adjusted gross income (AGI) as your total gross income minus certain, IRS approved, deductions. Your adjusted gross income deductions do not directly include deductions for small businesses or other common deductions, such as charitable contributions, interest paid and medical expenses. However, charitable contributions end up relating to AGI in an indirect manner.

Exemptions for AGI

Select expenses directly reduce your AGI up to an IRS established maximum level per expense. For example, a teacher may subtract up to $250 from his AGI to cover the cost of qualifying educational materials and supplies purchased out-of-pocket. Armed Forces reservists, performing artists and certain government officials may also claim an expense exemption through the filing of Form 2106, Employee Business Expense. Any person or family that moves over 50 miles to obtain or retain work can claim a portion of moving expenses to reduce AGI.

Deductions for AGI

Many of the AGI deductions apply to contributions made by self-employed and payroll employees towards retirement or health benefits. For example, a self-employed person can reduce her AGI through claiming health insurance payments, retirement plan contributions and 1/2 of her paid self-employment tax as deductions. All individuals are allowed to claim health savings accounts, IRA contributions, alimony, student loan interest and tuition costs as AGI deductions.

Charitable Donation Reporting

Donations to charity appear on the Schedule A for Form 1040, Itemized Deductions. Schedule A allows you to calculate and, potentially, report your total qualifying medical and dental expenses, taxes paid, interest paid, gifts to charity, casualty and theft losses, certain job expenses and miscellaneous deductions for a tax year. When Schedule A is completed, your final sum becomes your itemized tax deduction total. Unless you are required to itemize on your taxes, it is best to compare this deduction to the standard deduction assigned to you based on your filing status. The IRS encourages taxpayers to claim the higher of the two deductions.

Where AGI and Donations Meet

When your claim an itemized tax deduction on your income tax return, the total itemized deduction includes your charitable donations. To determine your total taxable income, you must subtract your itemized deduction sum from your AGI. This new number is then reduced by the total of your exemption deduction to arrive at your taxable income. When forms from other government departments, such as the Social Security Administration or Department of Education, request your AGI for benefit computations or financial aid awards, the AGI remains unaffected by your donations to charity.

Documentation

Always retain receipts provided to you by the charities you donate goods or funds to. If you are audited, these receipts or a cancelled check substantiate the itemized deduction total claimed on your income tax return. When a charity does not offer you a receipt, request one if you plan on reporting the donation on your taxes.
