What Deductions Can You Take on Federal Taxes? A No-Nonsense Guide
What deductions can you take on federal taxes? See rules for employees, freelancers, and filers 65+, plus itemized vs. standard deduction breakdowns.
Every April, someone tells you they're leaving money on the table with the IRS, and they're probably right. Deductions are the single biggest lever most people never pull, mostly because the rules feel like a maze designed to confuse you. Let's clear it up: here's what you can actually deduct on your federal return, whether you're a W-2 employee, a freelancer, or newly 65 and wondering what changes.
Key Takeaways
- Almost every filer chooses between the standard deduction and itemizing, not both.
- Itemizing only helps if your deductible expenses beat the standard deduction amount for your filing status.
- Self-employed people get a separate set of deductions on top of the standard/itemized choice.
- Turning 65 adds an extra standard deduction amount, so check the current IRS figure each filing season instead of guessing.
- Above-the-line deductions like IRA and HSA contributions work even if you don't itemize at all.
Standard Deduction or Itemized: How Do You Choose?
You pick whichever number is bigger, full stop. The standard deduction is a flat amount tied to your filing status that the IRS resets for inflation every year, and itemizing means totaling actual expenses like mortgage interest, state and local taxes, and donations. Whichever total is higher wins, and you don't get to combine them.
Here's what a lot of guides gloss over: taxpayers who take the standard deduction cannot also itemize their deductions. It's one or the other, every single year, though you can switch depending on how your finances shift.
Run the math both ways before you file. Tax software does this automatically in the background, but understanding why one option wins matters, because it tells you what to plan for next year. Buy a house, give more to charity, rack up medical bills? Your winning strategy can flip.
Most filers land on the standard deduction, and that's not laziness, it's math. The Tax Cuts and Jobs Act raised the standard deduction substantially starting with the 2018 tax year. That's exactly why charitable donations, medical expenses, mortgage interest, and local taxes can only be tax-deductible if you itemize, and why fewer people bother clearing that bar than you'd think.
What Deductions Can Individuals Actually Take?
Individuals get two buckets: above-the-line deductions that apply no matter what, and itemized deductions that only count if you skip the standard deduction — for the full rundown, see this complete tax deductions list. Knowing the difference is the whole game, because above-the-line write-offs are basically free money you don't need to fight for.
Above-the-line deductions (adjustments to income) reduce your taxable income before you even choose standard or itemized. This bucket includes:
- Traditional IRA contributions
- HSA contributions
- Student loan interest: there's a student loan deduction that lets you write off up to $2,500 of interest you paid on your student loans
- Educator expenses for qualifying teachers
Common itemized deductions only help if you're skipping the standard deduction:
- Mortgage interest
- State and local taxes, up to the federal cap
- Charitable donations
- Medical expenses above a percentage-of-income threshold
Deductions that skip the itemizing requirement entirely include self-employed health insurance premiums, alimony from divorce agreements finalized before 2019, and certain retirement contributions. These aren't itemized deductions, they're adjustments, and that distinction saves people real money every year.
One blunt piece of advice: check current IRS thresholds annually. Medical expense floors, SALT caps, and contribution limits move, and what was true for your 2024 or 2025 return isn't guaranteed to hold for your 2026 return. Don't carry forward a number from memory.
Federal Tax Deductions for People 65 and Older
Turning 65 hands you an extra standard deduction amount on top of the regular one, no itemizing required. The exact dollar figure changes yearly, so confirm it directly with the IRS or your tax software rather than trusting a number you saw somewhere last season.
This boost applies whether you take the standard deduction as a single filer or as part of a couple. And here's a detail people miss: if both spouses in a married couple are 65 or older, the extra amount stacks, doubling the benefit compared to a single qualifying spouse.
When Itemizing Starts to Make Sense After 65
Medical and dental expenses tend to loom larger as you age, and that changes the math. Once your unreimbursed medical costs clear the IRS's percentage-of-income threshold, itemizing can suddenly beat the standard deduction even with the age-based boost included.
There's another layer here that a lot of people ignore until it bites them: Social Security taxation and required minimum distributions interact with your deductions in ways that aren't obvious from a 1040 form alone. If you're navigating RMDs, a CPA review isn't a luxury, it's often the difference between a clean return and an expensive surprise.
Deductions for Freelancers and Small Business Owners
Self-employed people get an entirely separate deduction toolkit that stacks on top of the standard-versus-itemized choice everyone else makes. This is where freelancers and small business owners actually build wealth through the tax code, not despite it.
Home office deduction. You can deduct a portion of rent, utilities, and insurance based on the square footage used exclusively for business. Emphasis on exclusively. The IRS is not sympathetic to a kitchen table that doubles as a dinner spot.
Business expenses. Supplies, software subscriptions, mileage, professional development, and a portion of your self-employment tax all count. Keep receipts. This isn't optional advice, it's survival advice if you ever get a letter from the IRS.
Self-employed retirement contributions. A SEP IRA or solo 401(k) reduces your taxable income today while building retirement savings for later. Few moves in the tax code do double duty this well.
Depreciation. Big equipment and vehicle purchases don't have to hit your taxes all at once. Depreciation spreads the write-off across multiple years, which smooths out your tax bill instead of creating one enormous deduction in year one and nothing after.
Take a freelance graphic designer who deducts a home office, a slice of the internet bill, and software subscriptions used exclusively for client work. None of that requires itemizing personal expenses. It's a completely separate calculation running alongside the standard deduction decision.
Deduction Type Quick Reference
| Deduction Type | Who Can Claim It | Requires Itemizing? |
|---|---|---|
| Standard deduction | Every filer who doesn't itemize | No |
| Extra amount for age 65+ | Filers 65 or older, or blind | No, it adds to the standard deduction |
| Mortgage interest | Homeowners with a qualifying mortgage | Yes |
| Charitable donations | Anyone who donates to qualified organizations | Yes |
| Traditional IRA contribution | Eligible individuals with earned income | No, above-the-line |
| Home office deduction | Self-employed with dedicated business space | No, separate business deduction |
| Self-employed health insurance | Self-employed individuals paying their own premiums | No, above-the-line |
Deductions People Commonly Miss or Misuse
Most deduction mistakes aren't about greed, they're about sloppiness or confusion, and both are fixable. Here's where filers actually get burned:
Missing paperwork on charitable donations. No receipt or acknowledgment letter means an auditor can and will disallow the deduction, no matter how generous you actually were.
Home office claims for shared space. If the kids do homework at that desk on weekends, it's not exclusive business use, and the IRS knows the difference between a real deduction and wishful thinking.
Forgetting the SALT cap exists. The state and local tax deduction is capped at the federal level, period. Paying a fortune in property and state income tax doesn't mean you get to deduct all of it.
Confusing deductions with credits. A deduction shrinks your taxable income. A credit slashes your tax bill dollar for dollar. These are not interchangeable concepts, and mixing them up leads to bad planning decisions all year long.
Itemized deductions also aren't spread evenly across filers. The four largest itemized deductions are estimated to account for 17.8% ($241.2 billion) of the approximately $1.4 trillion in tax expenditures, which tells you the benefit concentrates among people with mortgages, big charitable gifts, and high state taxes. If that's not your profile, the standard deduction is probably doing you just fine.
Take a married couple, both 66, comparing whether their combined age-based standard deduction beats itemizing mortgage interest and donations. That comparison has to happen fresh every year. Refinance the mortgage, pay it off, change your giving? Rerun the numbers.
The Bottom Line
Deductions aren't a loophole, they're the rulebook working as intended, but only if you actually read it. Know your filing status, know your age bracket, know whether you're self-employed, and run the numbers both ways every single year instead of defaulting to whatever you did last time. The IRS isn't going to call you up and remind you what you're entitled to. That part's on you.
Frequently Asked Questions
Can I take the standard deduction and still deduct my IRA contribution?
Yes. IRA contributions are an above-the-line deduction, meaning they reduce your income before you even decide between standard or itemized. You get both.
Do I lose the extra deduction for being 65 if I itemize instead?
No, the additional amount for age 65 or older only adds to the standard deduction. If you itemize, that particular boost doesn't apply, but your itemized total might still come out ahead.
Is it worth hiring a CPA just to find more deductions?
If your return involves self-employment income, rental property, or you're navigating required minimum distributions after 65, probably yes. A good CPA often finds enough to cover their own fee.
What documentation do I actually need to keep for deductions?
Receipts, bank statements, mileage logs, and donation acknowledgment letters. The IRS can ask you to substantiate any deduction years after you file, so don't toss the paperwork early.
Are medical expenses easy to deduct?
Not really. You can only deduct the portion of unreimbursed medical expenses that exceeds a percentage-of-income threshold set by the IRS, which is a high bar for most healthy filers to clear.
