Can I switch between standard and itemizing each year?

Yes. Every year you file, you choose whichever method gives you the larger deduction. There's no commitment required. It makes sense to calculate both options every year, especially if your financial situation changes — you buy a home, have a large medical expense, or make a significant charitable donation.

What counts as an itemized deduction?

The main categories: state and local taxes (capped at $10,000), mortgage interest on your primary and secondary home, charitable contributions to qualified organizations, and certain unreimbursed medical expenses above 7.5% of your adjusted gross income. Some of these have their own limits and phase-outs.

Do I need receipts for everything if I itemize?

Yes. If you itemize, you need documentation to support each deduction — receipts, bank records, Form 1098 for mortgage interest, acknowledgment letters for charitable donations. You don't submit these with your return, but you need them if the IRS questions your deductions. Keep records for at least 3 years.

The Standard Deduction vs. Itemizing: Which Should You Choose? — Fiscal Word

Every April, most people answer the same question without realizing it: should I take the standard deduction or itemize? The choice determines how much of your income is shielded from taxes — and for most people, the answer became much simpler in 2018.

Here’s what each option means, who benefits from each, and how to know which one is right for you.

What Is the Standard Deduction?

The standard deduction is a flat dollar amount that the IRS lets you subtract from your income before calculating your tax bill. You don’t have to prove or document anything to claim it — it’s automatic.

For 2025, the standard deduction amounts are:

Single filers: $15,000
Married filing jointly: $30,000
Head of household: $22,500

These amounts are adjusted for inflation each year, so they’ll be slightly different by 2026. The IRS publishes updated figures each fall.

Here’s why it matters: if you’re a single filer who earned $65,000 in 2025, you subtract $15,000 and only pay taxes on $50,000. The standard deduction effectively makes your first $15,000 of income tax-free.

What Does “Itemizing” Mean?

Itemizing means instead of taking the flat standard deduction, you add up your actual qualifying expenses and deduct that total instead. You itemize when your qualifying expenses add up to more than the standard deduction.

The main categories of itemized deductions are:

State and local taxes (SALT) — your state income tax (or state sales tax, whichever is higher) plus local property taxes. Since 2018, this is capped at $10,000 total, regardless of what you actually paid.

Mortgage interest — interest paid on loans used to buy or improve your primary residence and a second home. There are limits on loan balances, but for most people this is a significant deduction.

Charitable donations — cash and non-cash contributions to qualified organizations. You generally need written acknowledgment from the organization for donations over $250.

Medical expenses — only the portion that exceeds 7.5% of your adjusted gross income. For someone earning $70,000, that means only medical expenses above $5,250 count. High medical expenses in a single year — a major surgery, a hospital stay — can sometimes clear this threshold.

The Simple Rule: Itemize Only When It’s Worth More

The math is straightforward: calculate your potential itemized deductions. If they total more than your standard deduction, itemize. If they don’t, take the standard deduction and be done with it.

That’s it. There’s no trick and no loyalty to either method — you pick whichever one lowers your tax bill.

You can switch every year. If you had a big year for mortgage interest and charitable giving, itemize. The next year, if your deductible expenses are lower, take the standard deduction. No commitment required.

Who Actually Benefits From Itemizing?

Before 2018, roughly 30% of tax filers itemized. Today, it’s closer to 10%. The reason: the 2017 Tax Cuts and Jobs Act nearly doubled the standard deduction, which meant itemized deductions needed to clear a much higher bar to be worthwhile.

Today, itemizing tends to make sense for:

Homeowners with large mortgages — particularly in the early years of a mortgage, when a higher portion of each payment goes to interest rather than principal. Someone with a $500,000 mortgage might pay $20,000–$25,000 in interest in their first year.

People in high-tax states — if you live in California, New York, New Jersey, or another state with high state income taxes, you’re already contributing the maximum $10,000 SALT deduction. Combined with mortgage interest, you can often clear the standard deduction threshold.

Large charitable donors — if you give 10-15% of your income to charity, those donations add up and can tip the scales toward itemizing.

People with very high unreimbursed medical expenses — an unusual year with major healthcare costs can sometimes make itemizing worthwhile, though the 7.5% floor is a high threshold.

A Concrete Example: Should This Homeowner Itemize?

Consider a married couple filing jointly in New York. Their deductible expenses for 2025:

State and local taxes (capped): $10,000
Mortgage interest on their primary home: $18,000
Charitable donations: $3,000
Medical expenses: Below the 7.5% threshold

Total potential itemized deductions: $31,000

Their standard deduction is $30,000.

The difference is only $1,000. At a 22% marginal rate, itemizing saves them roughly $220 more than taking the standard deduction. That’s worth doing — but barely. And next year, if their mortgage interest drops as they pay down the principal, the standard deduction may become the better choice.

Compare that to a couple with similar income but no mortgage and a lower SALT bill. Their itemized deductions might only add up to $12,000 — well below the $30,000 standard deduction. For them, itemizing would be a mistake.

What the 2017 Tax Law Changed

Before the Tax Cuts and Jobs Act of 2017, the standard deduction was $6,350 for single filers and $12,700 for married filers. That lower threshold made it worth itemizing for a much larger share of the population.

When the law nearly doubled those amounts — effective 2018 — the math shifted dramatically. Many people who used to itemize (particularly middle-class homeowners with modest mortgages) found the standard deduction was now larger than their total itemized deductions.

The result: roughly 90% of filers now take the standard deduction. For most people, the annual question has a clear answer.

The Honest Answer for Most People

If you don’t own a home with significant mortgage interest, don’t live in a high-tax state, and aren’t a large charitable donor, you’re almost certainly better off taking the standard deduction. The math won’t favor itemizing.

If you do own a home — especially a newer mortgage with high interest — it’s worth spending 20 minutes adding up your potential itemized deductions each year. The $10,000 SALT cap plus mortgage interest plus charitable giving can sometimes clear the bar.

Tax software does this automatically and will tell you which option saves you more. If you’re filing manually or with a CPA, ask them to run both calculations.
