Is business credit card interest tax-deductible?

When it comes to deducting credit card interest, the IRS draws a clear distinction between business use and personal use expenses. Per IRS code, you’re allowed to deduct interest on business charges but not personal ones. 

‍

There’s more to it than this, though, and in this article we'll break down everything business owners need to know about business credit card interest and its tax implications. That way, you can keep more money in your pocket and avoid any unpleasant surprises come tax time.

Is business credit card interest tax-deductible?

If your credit card is only used for business expenses, then the interest paid on those charges will be tax-deductible.

‍

However, if you use your business credit card for personal expenses as well, then you'll need to keep track of what amount of your balance was spent on business purchases. Then, come tax season, you'll be able to write off the percentage of your interest payments that are directly related to business expenses.

When can you deduct credit card interest?

Credit card interest is deductible whenever that interest is the direct result of a business purchase. Such purchases include:

• Travel: This includes any interest on purchases like fuel, airfare, hotel stays, food, and other travel-related expenses you incur as a result of your business operations.
• Entertainment: You can deduct interest rates for entertainment purchases—that is, as long as the entertainment is for business purposes. This includes things like taking your employees or clients out to dinner and a show.
• Office supplies: Any interest paid on balances that are the result of office equipment purchases can be written off.

When isn’t credit card interest tax-deductible?

You can't write off any credit card interest for personal purchases. For example, if you need to go to the doctor and use your business credit card, you won't be able to deduct the interest you pay on this portion of your balance.

‍

Also, keep in mind that there are tax breaks for personal expenses like student loans. However, whether you pay your student loan off with a personal credit card or your business card, this counts as a personal purchase.

‍

As such, the interest you pay on that portion of the balance isn't tax-deductible. So be sure you don’t trade credit card debt with tax-deductible interest for credit card debt that isn’t tax-deductible.

Is interest on a business line of credit tax-deductible?

Yes, interest charges on a business line of credit are tax-deductible as long as the loan meets the criteria established by the IRS and is used for business purchases. While the principal amount on business loans isn't deductible, the interest can be written off as a business operating expense, potentially leading to significant tax savings over time.

A brief history of credit card interest deductions

Prior to the 1980s, all types of consumer interest, including mortgage, credit card, and other personal interest, were generally deductible on U.S. federal income tax returns. 

‍

The major shift occurred with the Tax Reform Act of 1986, which was aimed at simplifying the tax code and eliminating many deductions in exchange for lower overall tax rates. Starting in 1987, the Act began phasing out the deductibility of personal interest, including that paid on credit cards.

‍

As of now, the deduction for personal card interest remains eliminated. This means when individuals pay interest on their credit card balances, this expense cannot be deducted from their taxable income. As we’ve explained, however, that does not extend to credit card interest on business-related purchases, which can be deducted. 

How to claim business credit card interest as a tax deduction

To claim your business credit card interest as a deduction on your income tax return, follow these steps:

Keep your receipts

Your credit card statements may be enough to justify your business expenses, including interest, but that’s not always the case. The Internal Revenue Service may decide that there’s not enough information on your credit card statement to determine whether the expenses were for your business or for personal reasons.

‍

To avoid any headaches, keep all of your receipts—or use a platform like Ramp, which automatically logs receipts and categorizes expenses for you.

Determine what percentage of your interest is tax-deductible

You can only deduct the percentage of your interest that results from business expenses. If that's all you use your business credit card for, then you can deduct 100% of your interest. If not, you’ll need to do some math to determine how much of your interest is tax-deductible.

‍

Let’s say you have a $10,000 balance. This balance consists of $7,500 in business purchases and $2,500 in personal purchases, and you paid a total of $2,000 in interest on the balance during the tax year.

‍

In this case, 75% of the balance is business-related, meaning that 75% of the interest you paid is tax-deductible. That works out to $1,500 in tax-deductible interest.

‍

If you’re not 100% sure of the percentage of your interest that you can deduct, consider reaching out to a tax professional.

File the proper forms

Finally, when you file your tax return, it’s important to file the right forms to claim your deductions. The forms you use to log these deductions depend on the type of business you have:

• Self-employed independent contractors without a separate business entity: Log your credit card interest on line 16b of Schedule C. You’ll file this with Form 1040.
• Partnerships and limited-liability companies: Partnerships and LLCs typically report credit card interest on line 15 of Form 1065.
• S corporations: S corporations log credit card interest deductions on line 13 of Form 1120-S.

Other tax implications of business credit cards

Taxable rewards and cashback

Business credit cards often come with rewards programs that offer cashback, points, or miles. While these rewards can be valuable, they're generally considered taxable income by the IRS. For more information about which credit card rewards are taxable, read our article on the subject.

Annual fees

Business credit cards often come with annual fees. The good news is that these costs are considered legitimate deductible business expenses when filing your taxes.

Employee card usage

If you provide employees with additional credit cards linked to your business account, be mindful of the potential tax implications. Make sure that personal charges made by employees on these cards are appropriately accounted for and excluded from business tax deductions to avoid any complications.

How Ramp can simplify your tax deductions

For small business owners, tax time can be particularly stressful—but it doesn’t have to be. 

‍

To simplify your taxes, consider Ramp. Ramp is a corporate card that automatically logs your receipts, categorizes your spending, empowers your employees, and integrates with your favorite accounting platforms to take the headaches out of money management and tax deductions.

‍

Ramp doesn’t have any of the typical credit card fees like annual fees, foreign transaction fees, or late fees. Because you’ll pay your balance in full each month, there are no interest charges. Plus, Ramp offers 1.5% cash back on purchases, saving your small business money on monthly expenses.
