Is Credit Card Interest Tax Deductible in 2026?

Under IRC Section 163(h), personal interest — including credit card interest on consumer purchases — is specifically excluded from deductibility.

This rule has been in effect since the phased elimination under the Tax Reform Act of 1986.

Credit card interest on personal purchases for clothing, groceries, entertainment, or other personal expenses cannot be deducted on federal returns.

This contrasts with the mortgage interest deduction, which remains available for qualifying home loans, and the student loan interest deduction, which provides a limited above-the-line deduction for qualifying education debt.

Personal auto loan interest is similarly excluded — see our guide on whether car loan interest is tax deductible for more detail.

Interest on credit card charges made for legitimate business purposes is deductible as a business expense under IRC Section 162.

Self-employed individuals deduct this on Schedule C.

If you use the same credit card for both personal and business purchases, only the interest attributable to business charges is deductible.

Keeping business and personal expenses on separate cards simplifies recordkeeping.

Self-employed workers claiming business credit card interest deductible treatment should maintain detailed records of the business purpose for each charge, consistent with how they document other Schedule C expenses like car insurance deductible for self-employed individuals.

Investment interest expense (interest paid to purchase taxable investments) is deductible as an itemized deduction under IRC Section 163(d), limited to net investment income.

Standard credit card interest is not investment interest.

However, if you specifically use a credit card or margin account to purchase investments, a portion may qualify as investment interest subject to Form 4952 limitations.

Taxpayers who actively invest may want to understand mutual funds and related investment vehicles and how interest on borrowing to fund investments interacts with IRS rules.

Since personal credit card interest is not deductible, the effective cost of carrying a balance is the full interest rate — typically 20% to 30% APR or more.

This makes paying down high-interest credit card debt a financially compelling priority, as there is no tax benefit to offset the cost of the interest, unlike mortgage interest deduction (which may be deductible within limits) or student loan interest deduction (which has a limited above-the-line deduction up to $2,500).

Building an adequate emergency fund size can also prevent the need to carry high-interest balances in the first place.
