Standard Deduction vs. Itemized Deductions: Which One Should You Choose?

Every January, the same question pops up in Korean-American group chats: "Should I take the standard deduction or itemize?" The honest answer is: it depends. Whether you own a home, how much you spent on medical care, what you gave to your church or community organizations, and how much you paid in state and local taxes can all flip the math entirely. This guide is written for tax year 2025 (returns filed in 2026). IRS rules change annually, so always verify the latest figures at IRS.gov before you file.

Here's the core difference. The standard deduction is a fixed dollar amount the IRS lets you subtract from your income automatically — no receipts required. Itemized deductions (Schedule A) require you to add up specific qualifying expenses and claim the actual total. Both methods reduce your taxable income and therefore your tax bill. The question is simply which one gives you a bigger number.

Standard Deduction Amounts for Tax Year 2025

The IRS adjusts the standard deduction each year for inflation. The amounts below reflect anticipated figures for tax year 2025 — confirm the final numbers in IRS Publication 501 at IRS.gov before filing.

• Single: $15,750
• Married Filing Jointly: $31,500
• Head of Household: $23,625
• Age 65 or older / legally blind: An additional amount is added on top of the base figures above.

These amounts reflect increases under the 2025 tax legislation (the One Big Beautiful Bill Act) and are indexed to inflation going forward. The practical takeaway: if you're married filing jointly and your itemized deductions don't add up to more than $31,500, the standard deduction wins — and you don't need to collect a single receipt.

When Itemizing Makes Sense — Scenarios Common in the Korean-American Community

So who should actually bother itemizing? Here are the situations that come up most often for Korean-American filers.

• Mortgage interest: If you're paying a mortgage, the interest portion is deductible on Schedule A. In high-cost markets like LA, New York, and New Jersey, annual mortgage interest alone can run $15,000–$25,000. The deduction applies to interest on loan balances up to $750,000 for homes purchased after December 15, 2017 (Form 1098 from your lender shows the exact amount).
• State and local taxes (SALT): Starting in 2025, the SALT deduction cap has increased significantly — from $10,000 to $40,000 for filers with modified AGI under $500,000 (the cap phases down above that threshold and is currently scheduled to revert to $10,000 in 2030). If you live in California, New York, or New Jersey and previously wrote off itemizing because of the old $10,000 cap, it's worth running the numbers again.
• Medical expenses: You can deduct the portion of unreimbursed medical expenses that exceeds 7.5% of your AGI. On an $80,000 AGI, that means only costs above $6,000 are deductible. This threshold matters most if you or a covered family member had a serious illness, surgery, or significant out-of-pocket costs — including situations where you sponsored a parent's immigration and took on their medical bills.
• Charitable contributions: Donations to IRS-recognized 501(c)(3) organizations — churches, Korean-American nonprofits, community foundations — are deductible. Cash donations of $250 or more require a written acknowledgment from the organization; a bank statement alone is not sufficient.

Add those figures up. If the total exceeds your standard deduction, itemizing saves you more money.

A Simple Four-Step Process to Figure Out Which Is Better

You don't need a finance degree to do this. Walk through these four steps.

• Step 1 — Gather your documents: Form 1098 (mortgage interest statement, mailed by your lender in late January), property tax payment records, state income tax paid (check last year's state return or your W-2), medical bills and insurance Explanation of Benefits (EOB) statements, and donation acknowledgment letters.
• Step 2 — Add everything up: Total all deductible expenses. That's your potential itemized deduction amount.
• Step 3 — Compare: Look up the standard deduction for your filing status and put the two numbers side by side.
• Step 4 — Choose: If your itemized total is higher, file Schedule A. If the standard deduction is higher — or even close — take the standard deduction and skip the paperwork.

Free tools that can walk you through this calculation include IRS Free File (IRS.gov/freefile — available at no cost if your income falls below the program threshold, which changes yearly), the free tiers of TurboTax and H&R Block, and the VITA program (Volunteer Income Tax Assistance). VITA provides free in-person tax help to low- and moderate-income filers. In Korean-American hubs like LA, New York, and Chicago, some VITA sites have Korean-speaking volunteers. Find your nearest location by searching "VITA locator" at IRS.gov or visiting 211.org.

Watch Out for These Korean-American-Specific Issues

General tax guides often miss situations that are particularly relevant for Korean-American filers. Keep these on your radar.

• F-1 and J-1 visa holders: If you're classified as a nonresident alien during any part of the year, you cannot take the standard deduction — you must file Form 1040-NR, and your itemized deductions are also restricted. Determining exactly when you cross over to resident alien status requires applying the Substantial Presence Test (see IRS Publication 519). Getting this wrong is one of the most common and costly mistakes among Korean students and researchers.
• Korean income or overseas accounts: Separate from your deduction choice entirely, if you hold foreign financial accounts or assets, you may have FBAR (FinCEN 114) and FATCA (Form 8938) reporting obligations. Missing these filings can trigger severe penalties that dwarf any tax savings from choosing the right deduction method.
• Paying medical bills for parents in Korea: You can only deduct medical expenses for yourself, your spouse, and your tax dependents. If you're sending money to cover a parent's medical costs in Korea but they don't meet the IRS definition of a dependent, those expenses are not deductible — regardless of how much you paid.

Three Mistakes That Are Easy to Avoid

• Missing or lost Form 1098: If your mortgage interest statement didn't arrive in the mail, log into your lender's online portal (Wells Fargo, Chase, Bank of America, etc.) and download it directly, or call and request a reissue. Claiming mortgage interest without this form is a red flag for an IRS audit.
• Claiming charitable donations without written acknowledgment: For any single donation of $250 or more — including church offerings — you need a written receipt from the organization, not just a bank record. Make it a habit to request an annual contribution statement from your church or nonprofit each January.
• Assuming your state return follows your federal return: Choosing to itemize on your federal return does not automatically mean you must itemize on your state return. California and several other states use their own deduction rules that differ from federal law. Always review your state filing separately.

Your Next Steps — Start Now

• Look up the current standard deduction for your filing status at IRS.gov (search Publication 501).
• Begin collecting Form 1098, property tax receipts, and donation acknowledgment letters — most arrive by late January.
• Check whether you qualify for free VITA assistance: search "VITA locator" at IRS.gov.
• Check IRS Free File eligibility at IRS.gov/freefile (income threshold varies by year).
• If your visa status is complicated or you have overseas assets, consult a Korean-American CPA or enrolled agent. For a straightforward individual return, fees typically run $200–$500 as of 2026; complex situations involving foreign income or business ownership will cost more.
