Choosing between a standard deduction or claiming itemized deductions is one of the main decisions taxpayers have to make every year. How you approach this issue could be quite critical to your tax bill. The standard deduction is nice because of its simplicity, but itemizing may be more beneficial to you if you have a lot of deductible expenses.

In this case, it will be more beneficial to you if you have a lot of deductible expenses. This is why we have this article on the subject.

What Are Itemized Deductions?

An expense a taxpayer incurred that can be deducted from his gross earnings subject to a tax is: "An itemized deduction". It is common practice to take itemized deductions within the confines of income earned in a year.

In this case, deducting the standard amount of income tax from gross income may not apply. Instead, you will have to add all the expenses and enter that in Schedule A of Form 1040. This means after the total of all the expenses is deducted from your gross income the amount subject to tax will be the net income.

Who Stands to Gain the Most from Itemized Deductions?

Itemizing is useful if you:

  • Have a built house on which you have taken a loan and pay hefty interest and property taxes on it.
  • Reside in a region that has exorbitant income and property taxes.
  • Sustained hefty medical and dental expenses out of your own pocket in the past year.
  • Make charitable donations on a regular basis or in substantial sums to approved charitable organizations.
  • Sustained a loss from a federally designated disaster zone.

Common Itemized Deductions

Below are the major deductions you are able to claim under IRS rules:

Medical and Dental Expenses: Out of pocket medical costs that are greater than 7.5% of your AGI are claimable. This includes surgeries, medical equipment, medical prescriptions or visits, etc.

SALT: Deductions available on state and local income taxes, as well as local sales and property taxes are capped. The total deduction is capped at $10,000 (5,000 if married filing separately).

Mortgage Interest: An exemption is available for the interest paid on a home mortgage and home equity loans for improvement up to $750,000 of debt for loans issued after December 15, 2017.

Charitable Contributions: Deductions may be offered for donations made in cash and property. Proper documented receipts and records must be kept and in some cases higher-value donations may require an appraisal.

Casualty and Theft Losses: If a federal government declares a disaster, personal casualty and theft losses resulting from it may be deductible. Other personal casualty or theft losses usually do not qualify for a deduction.

Other Limited Deductions: Some older miscellaneous deductions were suspended, but a few expenses—such as losses from gambling not exceeding winnings—are still allowable.

Itemized Deductions vs. Standard Deduction

Standard deductions are amounts set aside that single filers do not need to account for and can simply subtract from their taxable income.

Standard Deduction Amounts for 2025

  • Single or Married Filing Separately: $14,600
  • Head of Household: $21,900
  • Married Filing Jointly: $29,200

Deciding Which to Take

When expenses that can be deducted surpass the standard deduction amount, it usually makes the most sense to itemize.

When expenses that can be deducted do not surpass the standard deduction, it is likely that the standard deduction is simpler and will more often result in a lower amount paid in taxes.

For instance: A single filer who has $9,000 in state taxes and $6,000 in charitable donations can itemize ($15,000 in total) because it is more than $14,600 standard deduction.

How to Itemize on Your Tax Return

Collecting and saving physical copies of receipts, written notes, and documents that contain expenses is the more effective answer. This includes bills from medical visits and surgeries, receipts from taxable donation centers, and documents from tax evaluation centers.

From there, a Schedule A form can be filed which permits recording and organized assigning of expenses to their respective tax brackets.

The 1040 form is required and is sent alongside the Schedule A form. This is done to claim a tax return.

Helpful Tips

A useful technique that may be used is taxation software or seeking help from a professional who can help calculate the two values and help decide which is the more beneficial deduction to use.

Deductible expenses can be noted and recorded at any point throughout the year, but tax season will prove to be more difficult.

The limits of deductible charity contributions and the rules of interest on the mortgage should be verified.

Pitfalls and Limitations

There is no refund of the following taxes:

  • SALT Cap has a $10,000 limit on state and local taxes.
  • Medical expenses above 7.5% of AGI.
  • Phase Outs: Not all taxpayers are treated the same.
