Itemized Deductions: What It Means and How to Claim (2024)

When you file your taxes each year, you have the choice of taking the standard deduction or itemizing your deductions. The standard deduction is a preset amount that you are allowed to deduct from your taxable income each year. This amount will vary according to your tax filing status and is indexed annually to keep up with inflation.

Alternatively, taxpayers can elect to report itemized deductions. Itemized deductions are specific types of expenses the taxpayer incurred that may reduce taxable income. Types of itemized deductions include mortgage interest, state or local income taxes, property taxes, medical or dental expenses in excess of AGI limits, or charitable donations.

Standard vs. Itemized Deductions

Prior to the passage of TCJA, millions of taxpayers were able to claim a larger deduction on their tax returns by itemizing their deductions. Thanks to the higher standard deductions, this may no longer be necessary.

To make the most out of your tax return, read on to learn when to itemize your deductions and when to stick with the standard deduction.

Between the 2018 and 2025 tax years, when the TCJA will be in effect, the number of taxpayers for whom itemizing will pay off is likely to drop significantly due to the much bigger standard deduction.

(Two caveats: The personal exemption disappeared with the TCJA, which may offset this effect for some. On the other hand, the childtax credit doubled and applies to more families, which will push some returns in the other direction.)

The new law also eliminated a number of deductions taxpayers could take previously and changed some others.

The Purpose and Nature of Itemized Deductions

Itemized deductions fall into a different category than above-the-line deductions, such as self-employment expenses and student loan interest. They are below-the-line deductions, or deductions from adjusted gross income (AGI). They are computed on the Internal Revenue Service’s Schedule A, and then the total is carried over to your 1040 form.

When itemized deductions have been subtracted from your income, the remainder is your actual taxable income. Itemized deductions were created as a social-engineering tool by the government to provide economic incentives for taxpayers to do certain things, such as buy houses and make donations to charities.

Which Deductions Can Be Itemized?

Schedule A is broken down into several different sections that deal with each type of itemized deduction.

The following is a brief overview of the scope and limits of each category of itemized deduction. To help with future planning, we’ve included key changes under the new tax law, which mostly started applying from tax year 2018 on.

Unreimbursed Medical and Dental Expenses

This deduction is perhaps the most difficult—and financially painful for which one can qualify. Taxpayers who incur qualified out-of-pocket medical and/or dental expenses that are not covered by insurance can deduct expenses that exceed 7.5% of their adjusted gross income (AGI). This was originally scheduled to rise to 10% starting with the 2019 tax year (payable in April 2020).

However, the 7.5% threshold will remain in place at least through the 2022 tax year, thanks to an extension signed into law on Dec. 20, 2019.

Long-Term Care Premiums

Long-term care premiums are calculated slightly differently than medical expenses are. Long-term care insurance premiums are tax-deductible to the extent that the premiums exceed 10% of an individual's AGI. There is a deduction limit based on your age, and the insurance must be "qualified."

Home Mortgage and Home-Equity Loan (or Line of Credit) Interest

Home mortgage interest is deductible on the first $750,000 in loans.Each year, mortgage lenders mail Form 1098 to borrowers, which details the exact amount of deductible interest and points that they’ve paid over the past year.

Taxpayers who bought or refinanced homes during the year can also deduct the points they’ve paid, within certain guidelines. If the mortgage was originated before Dec. 16, 2017, then a higher limitation of $1 million applies. The higher limit still applies if you refinance that older mortgage, as long as the loan amount stays the same. For tax years after 2025, the $1 million limitation reappears regardless of when the loan was taken out.

Home-Equity Loan or Line of Credit Interest

Home-equity loan/line of credit interest is deductible provided that the borrowed funds are used to buy, build, or substantially improve the home that secures the loan.

Taxes Paid

Taxpayers who itemize are able to deduct two types of taxes paid on their Schedule A. Personal property taxes, which include real estate taxes, are deductible along with state and local taxes that were assessed for the previous year.

However, any refundreceived by the taxpayer from the state in the previous year must be counted as income if the taxpayer itemized deductions in the previous year. Starting in 2018 until the end of 2025, taxpayers can deduct only $10,000 of these combined taxes. In addition, foreign real estate taxes (not related to a trade or business) are not tax deductible.

Also, if you prepaid your state or local income tax for next year, that amount is not deductible on your current year’s taxes.

Charitable Donations

Any donation made to a qualified charity is deductible within certain limitations. For cash contributions between 2018 and 2025, the amount that can be deducted is limited to no more than 60% of the taxpayer’s AGI. Excess amounts must be carried over to the next year. Other contributions can be limited to 50%, 30%, or 20% of your AGI, depending on the type of property and organization receiving your donation.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act, signed into law on March 27, 2020, created a new above-the-line deduction of up to $300 for charitable donations and relaxed limits on other charitable deductions to increase charitable giving during the COVID-19 pandemic. These included cash contributions and donations of food, and they applied both to individuals and corporations. Note that the provisions passed in the CARES Act expired as of March 27, 2022.

Casualty and Theft Losses

Any casualty or theft loss incurred as a result of afederally declared disaster can be reported on Schedule A. Unfortunately, only losses in excess of 10% of the taxpayer’s AGI are deductible after subtracting $100 from the loss amount. If a taxpayer incurs a casualty loss in one year and deducts it on their taxes, any reimbursem*nt that is received in later years must be counted as income. Taxpayers must complete Form 4864 and report the loss on Schedule A.

Unreimbursed Job-Related Expenses and Certain Miscellaneous Deductions

Prior to the passage of the TCJA, workers incurring job-related expenses were able to deduct expenses that exceeded 2% of their AGI. Now, you must fall into one of four categories to be able to claim job-related expenses. You must be either an armed forces reservist, a qualified performing artist, a state or local government official working on a fee basis, or an employee with impairment-related work expenses.

Workers who fall into these categories and claim expenses must complete Form 2106. In addition, eligible educators may deduct up to $250 in unreimbursed expenses and can do so by completing Schedule 1.

Other Miscellaneous Deductions

This final category of itemized deductions includes items such as gambling losses to the extent of gambling winnings, losses from partnerships or subchapter S corporations, estate taxes on income in respect of a decedent (IRD), and certain other expenses. Some of these deductions are eliminated or changed from 2018 to 2025.For additional details, refer to the IRS Publication 5307 Tax Reform Basics for Individuals and Families and check with your tax advisor.

Summary of Tax Law Changes

If you’re filing as asingle taxpayerfor the 2022 tax year—or you’re married and filing separately—you will likely be better off taking the standard deduction of $12,950 if your itemized deductions total less than that amount (rising to $13,850 for the 2023 tax year).

The same applies to amarried couple filing jointlywho have no more than $25,900 for 2022 (and $27,700 in 2023) in itemized deductions and heads of household whose deductions total no more than $19,400 for 2022 ($20,800 in 2023).

These deductions almost doubled starting in 2018 after the passage of theTCJA.
