For tax year 2025 the standard deduction is $15,750 if you file single or married filing separately, $31,500 if you file jointly or as a qualifying surviving spouse, and $23,625 if you file as head of household. You take that amount with no receipts and no arithmetic. Itemizing only makes sense if your deductible expenses add up to more than it.
That single comparison is the whole decision. Everything below is about which side of it you land on.
Deduction is not the same as credit
A deduction reduces the income you are taxed on. A credit reduces the tax itself. If you are in a 22% bracket, a $1,000 deduction saves you roughly $220; a $1,000 credit saves you $1,000. People lose real money confusing the two, usually by chasing deductions while missing a credit they qualified for. We cover the other half of that in our guide to tax credits.
What gets added on top of the standard deduction
The standard deduction is not always a single flat number. Two additions matter for tax year 2025:
- Age or blindness. The additional standard deduction is $1,600 for 2025, rising to $2,000 if you are also unmarried and not a surviving spouse.
- The enhanced deduction for seniors. Beginning in 2025, taxpayers age 65 or older may be eligible for a deduction of up to $6,000, or $12,000 if married filing jointly and both spouses qualify.
Two more deductions that began in tax year 2025 are available whether you itemize or not: a deduction for qualified tips, and one for qualified overtime compensation of up to $12,500, or $25,000 for a joint return. Because they do not require itemizing, they do not change the standard-versus-itemized decision at all — they sit outside it.
Who cannot take the standard deduction
The IRS lists four situations where the standard deduction is off the table entirely:
- You are married filing separately and your spouse itemizes.
- You were a nonresident alien or a dual-status alien during the year, with some exceptions.
- You file for a period shorter than 12 months because you changed your accounting period.
- You are filing as an estate, trust, common trust fund or partnership.
The second one is not an edge case in South Florida. If you are filing on an ITIN because you are not eligible for a Social Security number, your residency status for tax purposes is the first thing to establish, because it determines whether this comparison even applies to you.
Why Florida makes itemizing harder to reach
Itemized deductions are mostly built from four categories: state and local taxes, mortgage interest, charitable contributions, and qualifying medical expenses above a floor.
The first category is where Florida residents fall behind. In a state with an income tax, residents accumulate state income tax withholding all year and that amount counts toward the state and local tax deduction. Florida has no personal income tax, so a Florida filer's state and local deduction comes from property taxes and, in some cases, sales tax paid — not from income tax withheld.
The practical consequence: a Florida household and a New Jersey household with identical incomes and identical mortgages will not reach the same itemized total, and the Florida one is more likely to be better off taking the standard deduction. That is not a rule you can look up. It is a comparison someone has to run for your actual numbers.
What this does not decide for you
Whether an expense qualifies at all, whether a floor applies before it counts, and how the pieces interact with credits is where the general answer stops being useful. If you have a mortgage, significant medical costs in one year, or income from more than one source, the arithmetic is worth doing properly rather than guessing at it in April.
