Tax credit vs tax deduction: what saves you more?
A tax credit directly reduces your tax bill dollar-for-dollar, while a tax deduction reduces the income your tax is based on.
For example, if both are US$1,000, the credit usually wins because it reduces tax directly, while a US$1,000 deduction only saves you your marginal rate on that amount. At a 22% bracket, a US$1,000 deduction saves about US$220.
Which credits vs deductions you’ll actually see?
- Credits: child tax credit, child and dependent care credit, American Opportunity/Lifetime Learning (education) credits, EV and other clean-energy credits, adoption credit, premium tax credit.
- Deductions: mortgage interest, SALT (subject to caps), charitable gifts, HSA and IRA contributions, self-employed expenses, student loan interest (income limits apply).
Which saves more money, a tax credit or a tax deduction?
In a straight comparison, credit > deduction at the same dollar amount. Deductions still matter a lot, especially at higher brackets and for business owners, but the math favors credits.
Which one benefits US expats more outside of the US?
- If you pay foreign income tax, the Foreign Tax Credit (Form 1116) is often the key tool because it can offset your US tax on the same income.
- If you use the Foreign Earned Income Exclusion (Form 2555), you may shrink or lose some credits that depend on taxable earned income or on having US tax to offset.
- Credits tied to US activities (EV purchases placed in service in the US, marketplace health coverage) usually require US-based facts and US tax liability to be useful.
You can use both FTC and FEIE at the same time!
However, FEIE reduces your FTC limit because you cannot claim a credit on taxes tied to excluded income, so overusing FEIE can waste foreign taxes you paid. In high-tax countries, FTC-only often wins; in lower-tax countries, a small FEIE plus FTC can be better.
Additionally, FEIE can shrink eligibility for credits tied to taxable earned income and does not remove US self-employment tax.
You can get your tax professional to balance out how to get the most of both of these while ensuring one doesn’t essentially undermine the other.

How do refundable vs nonrefundable tax credits work?
Refundable tax credits can create a refund even if you owe no tax, while nonrefundable credits can only reduce your tax to zero.
What’s the difference?
- Refundable credits can push your tax below zero and create a refund. Examples include parts of the child tax credit, the earned income credit, and the premium tax credit when you qualify.
- Nonrefundable credits reduce your tax down to zero, but any excess doesn’t pay out. Some allow carryforwards to future years.
How do they apply on the return?
You calculate tax on your income. Then you apply nonrefundable credits until you hit zero tax. After that, refundable credits can generate or increase a refund. If a nonrefundable credit is bigger than your tax and has no carryforward, the unused portion is lost for that year.
What’s the stacking order and what goes wrong most often?
- Use nonrefundable credits first, then refundable credits.
- Avoid overlapping education benefits in the same year for the same student and expenses, pick the stronger one.
- For EV/clean-energy items, confirm personal vs business use and placed-in-service dates, which affect credit type and any carryforward.
- Don’t double count by excluding income and also trying to claim a credit tied to that income.
- Keep proof: receipts, statements, VIN certifications, school 1098-T, dependent care provider info.
Can US expats use these outside of the US?
- Foreign Tax Credit: yes, central for many expats. It’s nonrefundable, but unused amounts may carry forward.
- Child tax credit: possible if the child has a valid SSN and you meet income and residency tests.
- Earned income credit: generally unavailable if you claim Form 2555 or if you don’t meet US presence rules.
- Premium tax credit: tied to a US marketplace policy; most expats without US coverage won’t qualify.
- Clean-energy and EV credits: typically require US-based property and other strict criteria; usefulness is uncommon if you live abroad full-time.
Education benefits: should you use education tax credits or a deduction?
Education tax credits usually save more than deductions because they directly reduce your tax, while deductions only lower taxable income.
For most families, the American Opportunity Tax Credit (AOTC) or the Lifetime Learning Credit (LLC) beats the old tuition-and-fees deduction in real savings.
AOTC vs LLC, side by side
- Maximum value
- AOTC: up to US$2,500 per student per year (first 4 years of undergraduate study).
- LLC: up to US$2,000 per return per year (any post-secondary level; no lifetime limit).
- Refundability
- AOTC: partially refundable, up to US$1,000 when you qualify.
- LLC: nonrefundable; it can bring your tax to zero, but it won’t pay you beyond that.
- Who qualifies
- AOTC: student must be at least half-time in a degree or credential program; can’t have used AOTC/Hope for more than four tax years; no felony drug conviction at year’s end.
- LLC: available for undergrad, grad, and professional courses; can be less than half-time and even one course.
- Expenses that count
- AOTC: tuition, required fees, and course materials needed for enrollment, even if bought off-campus.
- LLC: tuition and required fees; course materials count only if paid to the institution.
- Income phaseouts
- Both credits phase out at higher MAGI levels. If you’re near the threshold, model both credits to see which still delivers value.
- Paperwork checkpoint
- You generally need a 1098-T from an eligible institution, with limited exceptions. Keep invoices, proof of payment, and enrollment records.
Why credits usually beat a deduction
When the tuition-and-fees deduction was available, it reduced taxable income rather than tax itself, so a US$2,000-US$2,500 credit typically outperformed a similar-sized deduction unless your marginal rate was unusually high. Credits tend to produce clearer, bigger savings for most households.
How do I avoid double-dipping with a 529 plan?
You can’t use the same tuition dollar for both a credit and a tax-free 529 distribution. A common approach is to earmark US$4,000 of qualified expenses to unlock the full AOTC when you qualify, then apply remaining costs to the 529 distribution. Keep a simple worksheet that shows which expenses you assigned to each benefit.
Can US expats use these outside of the US?
Often, yes, if the school is an eligible educational institution and you meet all credit rules. Many foreign universities are eligible. You’ll still need proper documentation, and a 1098-T may not be issued by every foreign school, so follow the IRS rules on when a 1098-T is required or when exceptions apply.
Itemized deductions vs standard deduction: which should you take?
What’s the fastest way to decide?
Add up what you could itemize for the year, then compare it to your standard deduction for your filing status. If your mortgage interest + SALT + charitable gifts + medical over 7.5% of AGI is greater than the standard deduction, itemize.
If not, take the standard deduction. Credits apply either way, so always compare both paths, then add your credits.
When do people usually itemize?
- You paid meaningful mortgage interest or points on a qualified home loan.
- Your combined SALT (state income or sales tax plus property tax, subject to the cap) is sizeable.
- You made larger charitable gifts to US-qualified charities.
- Your medical expenses above 7.5% of AGI are high for the year.
When does the standard deduction usually win?
- You rent or have little mortgage interest.
- Your state tax and property tax are modest.
- Your charitable giving is smaller or to non-US charities that are not deductible.
- Medical costs did not exceed 7.5% of AGI.
Do tax credits phase out by income while deductions have caps and thresholds?
Yes. Many credits phase out as AGI rises, including the child credit, education credits, saver’s credit, EV and clean-energy credits, and the premium tax credit. Deductions are limited differently: the SALT cap, the 7.5% medical floor, and charitable percentage limits are common examples.
Which one benefits US expats more outside of US?
- Many expats take the standard deduction because they may not have US mortgage interest or state tax in a given year, and donations to non-US charities usually are not deductible.
- If you keep a US home, pay US property tax, and give to US-qualified charities, itemizing can still beat the standard deduction.
- If you use the Foreign Earned Income Exclusion, you may reduce US tax and make certain credits less valuable. If you rely on the Foreign Tax Credit, remember you cannot use the credit against tax on excluded income. Model both approaches before you file.
FAQs
Do business deductions also reduce self-employment tax?
Often yes. Ordinary Schedule C expenses lower your net profit, which reduces both income tax and self-employment tax; itemized deductions don’t affect SE tax.
Can above-the-line deductions help me qualify for income-based credits?
Can I take a deduction and a credit for the same expense (like education or an EV)?
Do states follow the federal rules on credits vs deductions for expats?
