Several types of contributions can reduce your taxable income, but the major categories are charitable donations, traditional IRA contributions, and Health Savings Account (HSA) contributions. Each has its own rules, limits, and documentation requirements that determine how much you can actually deduct.
Charitable Donations
Donations to qualified nonprofit organizations are tax deductible, but only if you itemize deductions on Schedule A instead of taking the standard deduction. For most people, the standard deduction is high enough that itemizing doesn’t make sense unless your total deductible expenses (mortgage interest, state and local taxes, charitable gifts, and a few other items) exceed it. If you take the standard deduction, your charitable giving won’t directly lower your tax bill.
When you do itemize, cash donations to most public charities are deductible up to 60% of your adjusted gross income (AGI). Contributions to certain private foundations, veterans organizations, and fraternal societies face a lower cap of 30% of AGI. Donations of appreciated property, like stocks you’ve held for more than a year, have their own percentage limits as well. If your giving exceeds these caps in a single year, you can generally carry the unused portion forward for up to five additional tax years.
What Counts as a Qualified Charity
Not every organization that asks for money qualifies. Deductible contributions must go to organizations recognized by the IRS under section 170(c), which includes religious organizations, nonprofit educational institutions, nonprofit hospitals, and public charities. Political campaigns, individuals, and most foreign organizations do not qualify. You can verify an organization’s status using the IRS Tax Exempt Organization Search tool before you give.
Donating Goods Instead of Cash
You can deduct the fair market value of clothing, household items, and other property you donate, but the items must be in good used condition or better. Think about what the item would actually sell for at a thrift store or consignment shop, not what you originally paid. If you’re claiming more than $500 for a single item that isn’t in good condition, you’ll need a qualified appraisal and must file Form 8283 with your return.
For any group of similar noncash items totaling more than $500 in claimed value, Form 8283 is required. If the total exceeds $5,000, you generally need a formal qualified appraisal signed by a credentialed appraiser. Keep receipts from every donation showing the organization’s name, the date, and a description of what you gave.
Vehicles have special rules. If you donate a car, boat, or airplane worth more than $500, your deduction is typically limited to the gross proceeds the charity receives when it sells the vehicle, not the Blue Book value. The charity must send you Form 1098-C within 30 days of the sale. Two exceptions let you deduct full fair market value: if the charity makes significant use of or materially improves the vehicle before selling it, or if the charity gives or sells the vehicle at well below market value to a person in need as part of its charitable mission.
Traditional IRA Contributions
Contributions to a traditional IRA may be fully or partially deductible, depending on whether you (or your spouse) participate in a retirement plan at work and how much you earn. If neither of you is covered by a workplace plan like a 401(k), your full IRA contribution is deductible regardless of income.
If you are covered by a workplace plan, deductibility phases out at certain income levels. For the 2026 tax year, single filers get a full deduction with modified adjusted gross income (MAGI) of $81,000 or less, a partial deduction between $81,000 and $91,000, and no deduction at $91,000 or above. Married couples filing jointly can deduct fully up to $129,000 in MAGI, partially between $129,000 and $149,000, and not at all at $149,000 or above.
The contribution limit for 2026 is $7,500 if you’re under 50, and $8,600 if you’re 50 or older. Even if your income is too high for a deduction, you can still make nondeductible contributions to a traditional IRA, though the tax benefit is limited to tax-deferred growth rather than an upfront deduction.
Health Savings Account Contributions
If you’re enrolled in a high-deductible health plan (HDHP), contributions to an HSA are deductible whether you itemize or not. This is an “above the line” deduction, meaning it reduces your adjusted gross income directly. For 2026, the contribution limit is $4,400 for individual coverage and $8,750 for family coverage.
To qualify for an HSA in 2026, your health plan must have a minimum annual deductible of $1,700 for self-only coverage or $3,400 for family coverage. Out-of-pocket maximums (excluding premiums) can’t exceed $8,500 for self-only or $17,000 for family plans, with exceptions for bronze and catastrophic plans. If your employer contributes to your HSA, those amounts count toward the annual limit and reduce the amount you can deduct on your own.
HSA contributions made through payroll deductions are typically pre-tax, meaning they never show up as taxable income in the first place. If you contribute outside of payroll, you claim the deduction on Form 8889 when you file. Either way, the money grows tax-free and comes out tax-free when used for qualified medical expenses, making HSAs one of the most tax-efficient accounts available.
Other Deductible Contributions Worth Knowing
A few other types of contributions can lower your tax bill. Self-employed individuals can deduct contributions to a SEP-IRA, SIMPLE IRA, or solo 401(k) as a business expense, with limits that are significantly higher than a standard IRA. Contributions to a 401(k) or 403(b) through your employer aren’t technically a “deduction” you claim on your return, but they reduce your taxable wages on your W-2, producing the same practical effect.
Student loan interest payments are deductible up to $2,500 per year as an above-the-line deduction, which doesn’t require itemizing. While not a “contribution” in the traditional sense, it’s a common deduction people overlook. Educator expenses up to $300 per year for teachers who buy classroom supplies also qualify as an above-the-line deduction.
Recordkeeping That Protects Your Deductions
The IRS can disallow a deduction entirely if you lack proper documentation. For any cash donation of $250 or more, you need a written acknowledgment from the charity that includes the amount, the date, and a statement about whether you received anything in return (like event tickets or a gift). For smaller cash gifts, a bank statement, canceled check, or receipt from the organization is sufficient.
For noncash donations under $250, keep a receipt showing the charity’s name, the date, the location, and a description of the property. Above $250, you need the same written acknowledgment required for cash gifts. At the $500 level, Form 8283 enters the picture. At $5,000, add a qualified appraisal. These thresholds are cumulative for groups of similar items, so donating furniture to the same charity across several trips in one year could push you past a reporting threshold even if no single trip seemed significant.
