The Standard Deduction vs. Itemizing: Which Saves You More?
Every year you sit down to file your taxes and face one major decision. Should you take the standard deduction or itemize your expenses? Making the right choice directly impacts how much you pay the IRS or how big your refund check will be. By comparing the exact numbers, you can discover the best tax filing strategy for your specific household.
Understanding the Standard Deduction
The standard deduction is a flat, no-questions-asked dollar amount that reduces your taxable income. You do not need to keep track of receipts or prove your expenses to claim it. Because the Tax Cuts and Jobs Act of 2017 nearly doubled this amount, almost 90% of American taxpayers now simply take the standard deduction.
The IRS adjusts these amounts every year for inflation. For the 2024 tax year (the taxes you file in early 2025), the standard deduction amounts are:
- Single filers: $14,600
- Married filing jointly: $29,200
- Head of household: $21,900
- Married filing separately: $14,600
If you are 65 or older, or if you are legally blind, the IRS gives you an extra bump. For 2024, a single filer who is 65 or older can add an extra $1,950 to their standard deduction. Married couples can add $1,550 for each qualifying spouse.
How Itemized Deductions Work
Itemizing is the alternative to the standard deduction. Instead of taking the flat rate, you list out your actual eligible expenses on a tax form called Schedule A. If the total of these specific expenses is larger than your standard deduction, you should itemize.
The IRS strictly limits what you can write off. Here are the most common itemized deductions available to taxpayers:
State and Local Taxes (SALT)
You can deduct the state income taxes, local taxes, and property taxes you paid during the year. However, federal law places a strict cap on this category. You cannot deduct more than $10,000 total in SALT per year ($5,000 if you are married but filing separately).
Mortgage Interest
Homeowners can deduct the interest paid on their primary mortgage. If you bought your house after December 15, 2017, you can deduct the interest on the first $750,000 of your mortgage debt. If you bought your home before that date, the limit is $1,000,000.
Medical and Dental Expenses
You can deduct out-of-pocket medical expenses, but there is a major hurdle. You can only deduct the portion of your medical expenses that exceeds 7.5% of your Adjusted Gross Income (AGI). For example, if your AGI is $100,000, 7.5% of that is $7,500. If you spent $10,000 on medical care, you can only deduct $2,500.
Charitable Contributions
Cash donations to qualified 501©(3) charities are deductible. You can also deduct the fair market value of goods donated to organizations like Goodwill or the Salvation Army. Keep in mind that you need written acknowledgement from the charity for any single donation over $250.
Running the Numbers for Your Household
To figure out which method saves you more money, you just need to do a little math. The rule is simple: choose the option that gives you the highest dollar amount.
Let us look at an example. John and Mary are a married couple filing jointly for the 2024 tax year. Their standard deduction is $29,200. During the year, they paid $8,000 in property taxes and state income taxes. They paid $12,000 in mortgage interest. They also donated $4,000 to their local food bank.
When they add up their itemized deductions, the total is $24,000. Because their $24,000 in itemized expenses is much lower than the $29,200 standard deduction, they should take the standard deduction. It saves them both time and tax dollars.
Now, imagine another couple, David and Sarah. They are also married filing jointly. They live in a high-tax state and easily hit the $10,000 SALT cap. They have a larger mortgage and paid $18,000 in interest. They also donated $5,000 to their church. Their total itemized deductions equal $33,000. For David and Sarah, itemizing is the clear winner. They will reduce their taxable income by an extra $3,800 compared to the standard deduction.
The Strategy of Bunching Deductions
If your itemized deductions are usually very close to the standard deduction limit, you might benefit from a strategy called “bunching.”
Bunching means grouping multiple years of deductible expenses into a single calendar year. For example, instead of donating $5,000 to charity every year, you could donate $10,000 in December of year one, and nothing in year two. You might also schedule an expensive elective surgery and pay your January property tax bill early in December.
By pushing all these expenses into one year, you force your itemized deductions high enough to beat the standard deduction. The following year, you simply drop back down and claim the standard deduction. Many wealthy taxpayers use a Donor-Advised Fund (DAF) at institutions like Fidelity Charitable or Vanguard Charitable to bunch their donations while distributing the money to charities over time.
Frequently Asked Questions
Can I claim the standard deduction and itemize at the same time?
No. You must choose one or the other on your federal tax return. You cannot combine them to get a larger tax break.
Do I need to keep receipts if I take the standard deduction?
You do not need receipts for the standard deduction itself. The IRS grants it automatically based on your filing status. However, you should still keep receipts for other above-the-line deductions, like contributions to a Traditional IRA or student loan interest payments.
Can I take the federal standard deduction but itemize on my state taxes?
Yes, depending on where you live. Some states (like California and New York) allow you to claim the standard deduction on your federal return but still itemize your deductions on your state return. You will need to check your specific state tax laws.
Does being an independent contractor change how I deduct expenses?
Business expenses are entirely separate from your standard or itemized personal deductions. If you are self-employed or work as a freelancer, you write off your business expenses on Schedule C. You can deduct things like software, business internet, and advertising on Schedule C, and then still claim the full standard deduction for your personal taxes.
