Standard vs. itemized deduction: how to tell which method saves you more

Every tax season, someone tells me they "always take the standard deduction," and someone else tells me they "always itemize because that's what my dad did." Both might be leaving money on the table. Why? The choice comes down to one comparison: is your itemized total bigger than your standard deduction? Here's how to run that comparison yourself, using the 2026 numbers.

What the standard deduction is

The standard deduction is a flat amount the IRS lets you subtract from your income with no receipts and no Schedule A. Everyone gets one, and it goes up a little each year. For tax year 2026 (the return you'll file in spring 2027), the amounts are:

If you're 65 or older, or blind, you get an extra deduction amount on top of these.

What itemizing means

Itemizing means adding up specific deductible expenses on Schedule A instead of taking the flat amount established by the IRS. You get to use whichever number is bigger. The big categories most people have are:

State and local taxes (SALT): property tax, plus state income tax or sales tax. For 2026 this is capped at $40,400 ($20,200 if married filing separately). The cap shrinks for higher earners once modified adjusted gross income passes $505,000, and it never drops below $10,000.

Mortgage interest: interest on up to $750,000 of home loan debt.

Charitable gifts: cash and property gifts to qualifying organizations. New for 2026, itemizers can only deduct gifts that go above 0.5% of adjusted gross income.

Medical and dental costs: only the part that's more than 7.5% of your adjusted gross income.

Heads up for business owners: business expenses don't go on Schedule A. Your equipment, software, mileage, and supplies are deducted on your business return no matter which route you take here. Itemized deductions are for personal expenses only.

The 10-minute test

Want to fill it in as you go? Grab the standard vs. itemized worksheet.

1. Add up your SALT, mortgage interest, charitable gifts (above the 0.5% floor), and medical costs (above the 7.5% floor).
2. Compare that total to the standard deduction for your filing status.
3. Take the bigger number.

Here's what that looks like for a married couple with $130,000 in adjusted gross income:

Couple B saves about $2,100 in federal tax by itemizing, assuming a 22% bracket. Couple A would lose about $2,200 if they itemized out of habit. Remember that a deduction isn't a refund. It lowers your taxable income, so the dollar value depends on your tax bracket.

The Virginia twist

Virginia wants you to be consistent. If you itemize on your federal return, you must itemize on your Virginia return. If you take the federal standard deduction, you take Virginia's, which is $8,750 for single filers and $17,500 for married couples filing jointly.

That matters because Virginia generally doesn't let you deduct state income tax as an itemized deduction. So, a federal itemized total that leans on a big state income tax number can shrink quite a bit on your Virginia return, sometimes below the Virginia standard deduction. When the federal comparison is close, run the Virginia numbers before you decide.

Two 2026 changes to note

Non-itemizers can now deduct some charity. Starting in 2026, if you take the standard deduction, you can still deduct up to $1,000 in cash gifts to qualifying charities ($2,000 if married filing jointly). Keep your receipts.

Itemizers face a new 0.5% floor on charity. That makes "bunching" more appealing. Bunching means putting two years of giving into one year, itemizing that year, and taking the standard deduction the next. If you're right on the line, it's worth a conversation before December 31.

If you own an S corporation or partnership, ask about Virginia's pass-through entity tax election. It's one way business owners work around the SALT cap, and it needs planning before the year ends, not in March.

Common mistakes

• Assuming a mortgage means you should itemize. With a $32,200 standard deduction for couples, plenty of homeowners in the Shenandoah Valley are better off with the flat amount.
• Forgetting the SALT cap. You can't deduct every dollar of property and state income tax you paid.
• Tossing records because you "always" take the standard deduction. Life changes. A new home, a big medical year, or a bump in charitable giving can flip your answer.
• Putting business expenses on Schedule A. They belong on your business return.
• Only checking the federal side. Virginia has its own math.

When to bring in a pro

If you're within a few thousand dollars of the line, or you have a business, rental income, or a big life change this year, run the numbers before year-end while you can still do something about it. That's the whole point of planning: you get to make moves in October instead of finding out in April.
