Key Takeaways

The Internal Revenue Service does not consider personal credit card interest tax deductible.
In some cases, you may be able to get a deduction on interest you paid on a business expense.
Ideally, you should separate your personal and business expenses so it's easier to find tax deductions.

You may be wondering if the credit card interest you pay could save you some money on your taxes. The answer depends on several factors including how you use your credit card and on what kind of expenses.

What is a tax deduction?

Imagine you have a piggy bank full of money. This money represents your taxable income. Every time you pay taxes, you take some of the money in the bank to pay the bill. But if you could say, "Hey, I spent some money on work, so I shouldn't have to pay tax on that part" that would be great, right? That's what ‘deductibility’ is.

According to the Internal Revenue Service (IRS), a tax deduction is an expense that can be subtracted from your income to lower how much you pay in taxes. Tax deductions are a good thing because they can help lower your taxable income, which may also reduce how much you owe in taxes.

Is credit card interest tax deductible?

When we talk about credit cards, some may immediately think of shopping, vacations, or dinners out. But there is much more to consider, especially when it comes to credit card fees, interest, and what expenses can be a tax deduction. Here is a more detailed overview:

Personal credit card use is not tax deductible

If you use your credit card for personal expenses, such as a new pair of jeans or the latest bestselling book, the interest accumulated on these expenses is not tax deductible. According to the IRS, credit card and installment interest incurred for a personal purchase does not count as a tax deduction.

Business credit card use may be deductible

If you’re an entrepreneur or have a small business, what’s deductible changes. Suppose you have a pizzeria, and you buy ingredients, equipment, or even advertising with your credit card. The interest on these purchases may be a business expense. And like many business expenses, they can be tax deductible according to the IRS. This means they can reduce your taxable income, and thus the amount of tax you must pay.

To sum up, whether you can deduct credit card interest depends on if the expense you’re paying interest on was a business or personal expense. If it was a business expense, it may be tax deductible, but if the credit card interest was because of a personal expense, you can’t use it as a deduction.

How to determine credit card interest deductibility

Determining credit card interest deductibility may seem like a challenge, but with a little organization and attention to detail, it can become much more manageable. Here is a detailed guide on how to do it:

Create a tracking system

First, you need an effective system to keep track of your expenses. It can be an app on your smartphone or even a simple spreadsheet. The most important thing is that you update it regularly.

Categorize your credit card spending

Every time you make a purchase with your credit card, make a note of the nature of the expense. For example, you can have categories such as 'business expense,’ 'personal expense,’ 'investments,’ and so on. This will help you quickly identify what interest might be deductible.

Keep receipts

Receipts may be key to helping you manage your tax deductions. Whenever you make a purchase that you think may be deductible, keep the receipt. This will not only help you prove deductibility in case of any tax audits but also provide you with a quick reference when preparing your tax return.

Review periodically

At least once a month, take some time to review your expenses and make sure you've put everything in the right category. This will help you avoid surprises at the end of the year and ensure that you are taking advantage of all available deductions.

Consult a professional

If you have doubts about the deductibility of certain interest or if your financial situation is complex, it may be useful to consult an accountant or financial advisor. They can provide you with expert guidance and ensure that you are following all the tax rules.

Keep an eye on tax laws

Tax laws can change. What is deductible this year may not be deductible next year. Therefore, it is essential to stay up to date on the latest regulations and tax changes.

Avoid common tax deduction mistakes

Mixed use of a credit card

Mixed use of a credit card, like using the same card for both personal and business purposes, can make figuring out your tax deductions more complex. Here's why:

Difficulty in tracking: If you use the same card for everything, you may have difficulty distinguishing between personal and business purchases. This can make it complicated to determine how much interest is deductible.
Unintentional errors: Without a clear separation between business and personal use, you may accidentally deduct personal expenses, which may cause problems in the event of a tax audit.

Solution: Consider having two separate cards: a personal credit card and a business credit card. This will help you keep expenses separate and simplify the deduction process.

High interest credit card debt

Having a credit card can be useful, but if the interest rate is too high, you may find yourself in a challenging situation. Here are some things to consider:

Long-term costs: Even if you can deduct some of the interest, the long-term costs of maintaining a high balance on a card with a high interest rate could outweigh any tax benefit.
Impact on credit score: Having a high balance compared to your credit limit may impact your credit utilization and thus your credit score. Your credit utilization makes up about 30% of your credit score (depending on the scoring model used). A lower credit score may make it more difficult to obtain loans or other forms of credit in the future.

Solution: If possible, try to pay off your credit card balance every month, it can help you avoid an interest charge. If this is not possible, consider transferring the balance to a card with a lower interest rate or look for other solutions to reduce your debt.

The bottom line

Credit card interest can help you save on taxes. But it depends on how you use your card. The important thing is to have good organization habits, keep track of your expenses and, when in doubt, ask a financial advisor for help.
