Investment Expenses: What's Tax Deductible? (2024)

No more deduction for miscellaneous investment-related expenses

For tax years 2018 to 2025, "miscellaneous itemized deductions" have been eliminated. Prior to the Tax Cuts and Jobs Act of 2017 (TCJA), taxpayers were allowed to deduct expenses such as fees for investment advice, IRA custodial fees, and accounting costs necessary to produce or collect taxable income.

For tax years 2018 to 2025, "miscellaneous itemized deductions" have been eliminated. Prior to the Tax Cuts and Jobs Act of 2017 (TCJA), taxpayers were allowed to deduct expenses such as fees for investment advice, IRA custodial fees, and accounting costs necessary to produce or collect taxable income.

If you itemize, you may be able to deduct the interest paid on money you borrowed to purchase taxable investments—for example, margin loans to buy stock or loans to buy investment property. You wouldn't be allowed to deduct the interest on a loan to buy tax-advantaged investments such as municipal bonds.

The amount that you can deduct is capped at your net taxable investment income for the year. Any leftover interest expense gets carried forward to the next year and can potentially be used to reduce your taxes in the future.

To determine your deductible investment interest expense, you need to know the following:

• Your net investment income, which normally includes ordinary dividends and interest income. It does not include investment income taxed at the lower, long-term capital gains tax rates or municipal bond interest, which is not taxed at all.
• Your total investment interest expenses for loans used to purchase taxable investments.

Let's look at an example. Here, Mary has $150,000 of total income, $8,000 of net investment income (from ordinary dividends and interest income), $10,500 of investment interest expenses from a margin loan, and $13,000 of other itemized deductions (such as mortgage interest and state taxes).

Qualified dividends that receive preferential tax treatment aren't considered investment income for these purposes. However, you can opt to have your qualified dividends treated as ordinary income.

In the right circ*mstances, electing to treat qualified dividends as ordinary income can increase your investment interest expense deduction, which could allow you to pay 0% tax on the dividends instead of the 15% or 20% tax that qualified dividends normally receive. Here's an example of how it might work.

In addition to the information in the first example, let's say Mary has $2,000 of qualified dividends, on which she would normally pay $300 in tax ($2,000 x 15% long-term capital gains tax rate). If Mary elected instead to treat the qualified dividends as ordinary income, she could boost her net investment income from $8,000 to $10,000. As a result, she would be able to deduct more of her investment interest expense in the current year—and pay no tax on the qualified dividends.

Because Mary is a tax-savvy investor, she was able to reduce her taxable income from the original $150,000 to $127,000. That $10,000 investment interest expenses deduction resulted in $2,220 of tax savings (assuming an ordinary tax rate of 24% and a long-term capital gains tax rate of 15%).

Note: The election to treat qualified dividends as ordinary dividends should not be taken lightly. Once made, the election can only be revoked with IRS consent. Consult with your tax professional before implementing this tax strategy.

Losing money is never fun, but there might be a silver lining. Capital losses can be used to offset your capital gains. If your capital losses exceed your capital gains, up to $3,000 of those losses (or $1,500 each for married filing separately) can be used to offset ordinary income and lower your tax bill. Net losses of more than $3,000 can be carried forward to offset gains in future tax years.

To make the most effective use of capital losses, keep track of your investment cost basis. The cost basis is generally equal to an investment's purchase price plus any expenses necessary to acquire that asset, such as commissions and transaction fees.

The IRS also has some resources that provide examples and detailed explanations of the topics included in this article, including: Publication 550, Publication 529, and the instructions for Form 1040, Schedule A, Schedule D, and Form 4952.

Be sure to consult your tax professional (CPA, lawyer, or enrolled agent) about your situation, preferably well before the end of the year. No matter the time of year, it's also a good idea to check with your tax advisor before you make any decisions that might have significant tax consequences.
