Step-by-Step: How to Deduct Charitable Donations on Your Taxes

Overview: Why and When to Deduct Charitable Donations

Charitable deductions represent one of the most valuable tax benefits available to individual taxpayers. When properly claimed, these deductions can reduce your taxable income dollar-for-dollar, potentially saving you hundreds or thousands of dollars in taxes. However, claiming charitable deductions requires careful attention to detail and strict adherence to IRS requirements.

Key Point

You can only deduct charitable donations if you itemize your deductions using Schedule A. If your total itemized deductions don't exceed the standard deduction, you won't benefit from charitable deductions on your federal return.

When Charitable Deductions Make Sense

For 2025, the standard deduction amounts are:

Filing Status	Standard Deduction
Single	$15,000
Married Filing Jointly	$30,000
Married Filing Separately	$15,000
Head of Household	$22,500

Your itemized deductions (including charitable donations, mortgage interest, state and local taxes, and medical expenses) must exceed these amounts for charitable deductions to provide tax benefits.

Step 1: Verify Eligibility to Claim Deductions

Before diving into forms and calculations, ensure you're eligible to claim charitable deductions and that your donations qualify.

Personal Eligibility Requirements

Itemization Decision: You must choose to itemize deductions rather than take the standard deduction
U.S. Taxpayer Status: You must be filing a U.S. tax return (Form 1040)
Donation Timing: Contributions must have been made during the tax year you're filing for
No Direct Benefit: You cannot receive significant goods or services in return for your donation

Qualified Organizations

Verify that your donations went to IRS-qualified organizations:

501(c)(3) organizations (most common charitable organizations)
Religious organizations (churches, synagogues, mosques, etc.)
Government entities for public purposes
Qualified veterans' organizations
Domestic fraternal societies operating under the lodge system

Verification Tool

Use the IRS Tax Exempt Organization Search (TEOS) at irs.gov to confirm an organization's eligibility before claiming deductions.

Step 2: Gather Required Documentation

Proper documentation is crucial for defending your charitable deductions. The requirements vary based on the type and amount of your contributions.

Cash Contributions Documentation

Contribution Amount	Required Documentation
Under $250	Bank record (canceled check, credit card statement) OR charity receipt
$250 or more	Written acknowledgment from charity (must be contemporaneous)
Payroll deductions	Pay stub, W-2, or other employer-provided document

Non-Cash Contributions Documentation

Property Value	Required Documentation
Under $250	Receipt from charity with date, location, and description
$250 - $500	Written acknowledgment from charity
$501 - $5,000	Written acknowledgment + Form 8283 Section A
Over $5,000	Qualified appraisal + Form 8283 Section B
Over $500,000	Appraisal must be attached to tax return

Essential Elements of Written Acknowledgments

For any single contribution of $250 or more, you need a written acknowledgment containing:

Name of the charitable organization
Date of the contribution
Amount of cash contributed or description of non-cash property
Statement indicating whether you received any goods or services
If goods/services were provided, a description and good faith estimate of their value

Critical Timing Requirement

"Contemporaneous" means you must receive the written acknowledgment before the earlier of: (1) the date you file your return, or (2) the due date (including extensions) for filing your return.

Step 3: Calculate Total Donation Values

Accurately calculating the value of your charitable contributions is essential for proper reporting and avoiding audit issues.

Cash Contributions Calculation

For cash donations, the calculation is straightforward—use the actual amount donated. Include:

Check and electronic payments
Credit card charges (use the date charged, not when you pay the bill)
Payroll deductions
Text message donations
Online platform contributions

Non-Cash Property Valuation

For non-cash contributions, you must determine fair market value (FMV)—the price property would sell for between a willing buyer and seller.

Common Property Types and Valuation Methods:

Property Type	Valuation Method	Special Considerations
Clothing/Household Items	Thrift store prices	Must be in good condition or better
Publicly Traded Securities	Average of high/low on gift date	Use closing price if no trading
Vehicles	Actual sale proceeds by charity	Charity provides Form 1098-C
Real Estate	Professional appraisal	Required for gifts over $5,000
Artwork/Collectibles	Qualified appraisal	Subject to additional restrictions

Overvaluation Penalty Warning

The IRS imposes significant penalties for overvaluing donated property. When in doubt, use conservative estimates and document your valuation method.

Step 4: Complete Schedule A (Form 1040)

Schedule A is where you report all itemized deductions, including charitable contributions. Here's how to properly complete the charitable contribution section.

Schedule A Lines for Charitable Contributions

Line 11: Gifts to charity by cash or check
Line 12: Other than by cash or check (non-cash contributions)
Line 13: Carryover from prior year
Line 14: Add lines 11 through 13 (total charitable contributions)

Detailed Filing Instructions

Line 11 - Cash Contributions:

Sum all cash donations made during the tax year
Include check payments, electronic transfers, credit card charges
Include payroll deductions
Do not exceed 60% of your AGI (excess carries forward)

Line 12 - Non-Cash Contributions:

Report fair market value of donated property
For appreciated property held longer than one year, use full FMV
For property held one year or less, use the lesser of FMV or your basis
Attach Form 8283 if total non-cash contributions exceed $500

Line 13 - Prior Year Carryover:

Include unused charitable deductions from previous years
You can carry forward unused deductions for up to five years
Use the oldest carryforward amounts first

AGI Limitation Strategy

If your charitable contributions exceed AGI limits, consider the timing of future contributions and whether to elect the reduced deduction for appreciated property to increase current-year benefits.

Step 5: File Form 8283 for Non-Cash Contributions (When Required)

Form 8283 is required when your total non-cash charitable contributions exceed $500. The form has two sections with different requirements.

Form 8283 Section A (Property Worth $500-$5,000)

Complete Section A for each item or group of similar items donated with a value between $500 and $5,000:

Part I: Information about donated property
Part II: Partial interests and restricted use property
Part III: Taxpayer (donor) statement

Required Information for Section A:

Description of donated property
Date of contribution
Date acquired by donor
How property was acquired (purchase, gift, inheritance, etc.)
Donor's cost or adjusted basis
Fair market value on contribution date
Method used to determine fair market value

Form 8283 Section B (Property Worth Over $5,000)

Section B requires additional documentation and must be signed by a qualified appraiser:

Complete qualified appraisal required
Appraiser must sign Form 8283
Charitable organization must acknowledge receipt
Special rules apply for certain types of property

Qualified Appraiser Requirements:

Must be a qualified appraiser under IRS regulations
Cannot be the donor, charity, or related party
Must be qualified to appraise the specific type of property
Must include appraiser declaration on Form 8283

Special Property Rules

Certain property types (vehicles, intellectual property, taxidermy, etc.) have special valuation and reporting requirements. Consult IRS Publication 526 for specific guidance.

Step 6: Apply AGI Percentage Limitations

Charitable deductions are subject to percentage limitations based on your Adjusted Gross Income (AGI). Understanding these limits helps you maximize current deductions and plan future giving.

2025 AGI Percentage Limits

Type of Contribution	Type of Organization	AGI Limit
Cash	Public charities	60%
Appreciated property (long-term capital gain)	Public charities	30%
Cash	Private foundations	30%
Appreciated property	Private foundations	20%

Applying the Limitations

Follow this order when applying AGI limitations:

Calculate your AGI from Form 1040
Apply the 60% limit to cash contributions to public charities
Apply the 30% limit to appreciated property to public charities
Apply lower limits for contributions to private foundations
Carry forward any excess amounts to future years

AGI Limit Example

If your AGI is $100,000 and you donated $80,000 cash to public charities, you can deduct $60,000 (60% × $100,000) this year and carry forward $20,000 to next year.

Special Election for Appreciated Property

You can elect to use the 60% limit for appreciated property by reducing your deduction to the property's basis rather than fair market value. This election might be beneficial when:

The 30% limitation significantly restricts your current deduction
You have little appreciation in the donated property
You want to maximize current-year tax benefits

Step 7: Handle Charitable Contribution Carryforwards

When your charitable contributions exceed AGI limits, the excess can be carried forward for up to five years. Proper tracking and reporting of carryforwards ensures you don't lose valuable deductions.

Carryforward Rules

Five-year limit: Unused deductions expire after five years
First-in, first-out: Use the oldest carryforward amounts first
Same AGI limits apply: Carryforward deductions are subject to the same percentage limitations
No carryback: You cannot carry excess deductions back to prior years

Tracking Carryforwards

Maintain detailed records of carryforward amounts by year and type:

Contribution Year	Type	Original Excess	Used in Prior Years	Available for Current Year
2021	Cash	$10,000	$8,000	$2,000
2023	Property	$15,000	$5,000	$10,000

Reporting Carryforwards

Report carryforward amounts on Schedule A, Line 13
Attach a statement detailing carryforward calculations if amounts are significant
Keep permanent records of carryforward computations
Consider professional help for complex carryforward situations

Carryforward Expiration Risk

Charitable contribution carryforwards expire after five years. Monitor expiration dates and consider timing strategies to maximize their use before expiration.
