Standard Deduction vs. Itemized: Which Should You Take?
Every taxpayer gets a choice: take the standard deduction (a fixed amount based on filing status) or itemize deductions (list every qualifying expense). You should take whichever is larger, because that reduces your taxable income the most.
For 2024, roughly 87% of American taxpayers take the standard deduction because it was nearly doubled by the Tax Cuts and Jobs Act of 2017, making itemizing beneficial for fewer people.
✅ Standard Deduction
- Fixed amount: $14,600 (single), $29,200 (MFJ)
- No receipts or tracking needed
- Taken by ~87% of filers
- Best for most people without major expenses
- Extra amount for age 65+ or blind
📝 Itemized Deductions
- Requires tracking and documentation
- Use Schedule A with your return
- Worthwhile if your deductions exceed standard amount
- Includes mortgage interest, state taxes, charity
- Required for some high-income taxpayers
💡 The Decision Rule
Add up your potential itemized deductions. If they exceed $14,600 (single) or $29,200 (married filing jointly), itemize. Otherwise, take the standard deduction. Tax software will automatically calculate both and choose the better option.

Above-the-Line Deductions (Everyone Can Take These)
Above-the-line deductions (officially called "adjustments to income") reduce your Adjusted Gross Income (AGI) and can be taken regardless of whether you itemize or take the standard deduction. These are found on Schedule 1 of Form 1040 and are some of the most valuable deductions available.
Student Loan Interest
Up to $2,500Deduct up to $2,500 of interest paid on qualified student loans. Phases out at $75,000–$90,000 (single) or $155,000–$185,000 (MFJ). You must have borrowed to pay for your own, spouse's, or dependent's education.
IRA Contributions
Up to $7,000 / $8,000 (50+)Contributions to a traditional IRA may be deductible. The 2024 limit is $7,000 ($8,000 if age 50+). Deductibility phases out if you have a workplace retirement plan and income exceeds certain thresholds.
Health Savings Account (HSA)
$4,150 self / $8,300 familyContributions to an HSA are fully deductible above the line. For 2024: $4,150 (self-only) or $8,300 (family). Must be enrolled in a High Deductible Health Plan (HDHP). Funds roll over and grow tax-free.
Self-Employment Tax Deduction
50% of SE taxIf you're self-employed, you pay 15.3% self-employment tax (FICA). You can deduct half of what you pay as an above-the-line deduction, reducing your adjusted gross income.
Self-Employed Health Insurance
100% of premiumsSelf-employed individuals can deduct 100% of health insurance premiums for themselves and their families as an above-the-line deduction. Not available if you're eligible for employer-sponsored coverage.

Up to $300K-12 teachers, principals, and aides who work at least 900 hours per year can deduct up to $300 ($600 MFJ if both are educators) in classroom supplies and materials purchased out-of-pocket.
Itemized Deductions: The Full List
If your total itemized deductions exceed the standard deduction, you file Schedule A. Here are all the major itemized deductions available for 2024:
State and Local Taxes (SALT)
You can deduct state and local taxes paid, but the SALT deduction is capped at $10,000 ($5,000 MFS) total. This cap was introduced by the TCJA in 2017. Qualifying taxes include:
- State and local income taxes (or sales taxes, as an alternative)
- Real estate (property) taxes on your home(s)
- Personal property taxes (such as vehicle registration fees based on value)
⚠ SALT Cap Warning
Residents of high-tax states like California, New York, and New Jersey often hit the $10,000 SALT cap quickly. If you pay $15,000 in state income and property taxes, you can only deduct $10,000. This is one reason many high-earners in high-tax states lost significant deductions after 2017.
Mortgage Interest Deduction
Interest paid on a home mortgage is deductible on loans up to $750,000 ($375,000 MFS) in principal — for mortgages originated after December 15, 2017. For older mortgages, the limit is $1,000,000. This includes:
- Primary home mortgage interest
- Second home mortgage interest (within the same $750K limit)
- Points paid to obtain a mortgage (may be deductible immediately or amortized)
- Home equity loan interest — only if used to buy, build, or substantially improve the home
Charitable Contributions
Cash donations to qualifying 501(c)(3) organizations are deductible up to 60% of your AGI. Non-cash contributions (such as donated property) are generally limited to 30% or 50% of AGI depending on the type of property and recipient organization. Requirements:
- Donation must be to a qualifying tax-exempt organization (verify at IRS Tax Exempt Organization Search)
- Cash donations over $250 require written acknowledgment from the organization
- Non-cash donations over $500 require Form 8283
- Non-cash donations over $5,000 generally require a qualified appraisal
Medical and Dental Expenses
You can deduct medical expenses that exceed 7.5% of your Adjusted Gross Income (AGI). Only the amount above this threshold is deductible. For example, with $60,000 AGI, only medical expenses over $4,500 (7.5%) can be deducted. Qualifying expenses include:
- Health insurance premiums (if paid with after-tax dollars)
- Doctor, hospital, and dental fees
- Prescription medications
- Vision, hearing aids, and medical equipment
- Long-term care insurance premiums (subject to age-based limits)
- Transportation to medical appointments
