Did you know that grace periods on credit cards provide a convenient window to pay off major purchases without accruing interest? But, if you don’t pay your balance in full by the due date, that grace period vanishes—leaving you to shoulder interest charges, according to Chase.
For business owners, this distinction is vital when it comes to taxes. Is credit card interest deductible for business expenses? In this article, discover how to maximize deductions, avoid costly mistakes, and navigate the IRS rules for 2025.
What Qualifies as Deductible Credit Card Interest for Business Owners?
How Does the IRS Define Deductible Interest?
When it comes to interest on credit cards, the IRS makes a clear distinction: only interest paid on business-related credit card charges qualifies for a tax deduction. If you use a credit card for personal expenses, the interest you pay on those charges is considered personal interest, which has been non-deductible since the Tax Reform Act of 1986. For small business owners, this rule highlights the importance of separating your business card from your personal accounts to avoid complications during tax filing.
What Types of Business Purchases Qualify?
Interest is deductible when it’s tied to credit card charges that directly support your business operations. These could include:
- Buying office supplies or equipment.
- Paying for credit card fees associated with business transactions.
- Covering credit card charges for software, subscriptions, or cash advances for business needs.
- Expenses related to travel or marketing.
To maximize your tax savings, ensure that all purchases are related to business, and use one dedicated credit card for business expenses. Keeping clear records, like an itemized credit card statement, helps substantiate your claims during tax preparation.

How to Accurately Claim Credit Card Interest on Your Business Taxes
What Records Should You Keep?
To claim an interest deduction, you’ll need detailed and accurate records. These include:
- Monthly credit card statements that clearly outline all credit card charges, including interest payments.
- Proof of business-related expenses like receipts, invoices, or logs.
- Records from accounting software to track deductible business expenses, such as interest paid.
Using tools like QuickBooks helps you organize these records and ensures you’re prepared when tax time comes. A well-documented system can also safeguard you in case of an IRS audit.
How Do You Allocate Interest for Mixed-Purpose Cards?
If you use a credit card for both business and personal expenses, you’ll need to separate the interest paid based on the percentage of business-related purchases. Here's how to allocate it:
- Calculate the total credit card balance for the month.
- Determine what percentage is tied to business charges versus personal purchases.
- Apply this percentage to the interest on the credit card for the month.
Example: If your credit card issuer charges $100 in interest and 60% of the expenses were for business, you can deduct the interest on $60.
To avoid these calculations and simplify your tax situation, consider using separate cards for business and personal expenses.

Strategies for Small Business Tax Planning and Compliance in 2025
Why Should You Use a Business-Only Credit Card?
Using a dedicated credit card for business is one of the smartest strategies for small business owners. Here’s why:
- It ensures that only deductible business expenses appear on one account.
- You’ll avoid mixing business and personal charges, which reduces confusion during tax preparation.
- Many credit card companies provide categorized monthly reports, making it easier to track interest paid and prepare your tax return.
- It helps improve your credit history and credit score, which is important if you plan to apply for a new card or financing.
What Tax-Planning Tools Should You Leverage?
Effective small business tax planning starts with tools that streamline your processes and uncover deductions you might otherwise overlook. Here’s how to make the most of them:
1. QuickBooks Online for Comprehensive Tracking
QuickBooks isn’t just for bookkeeping—it’s a tax-planning powerhouse:
- Automatic Categorization: It tags credit card charges and separates tax-deductible expenses from non-deductible ones, saving you hours of manual work.
- Interest Calculations: Tracks interest paid on credit card debt, including for mixed-use accounts, and flags amounts eligible for deductions.
- Custom Reports: Generates reports tailored for tax filing, ensuring you have everything you need when preparing your tax return or working with your CPA.
2. Work with a Tax Professional
No software can replace the expertise of a seasoned tax advisor:
- Identify Missed Deductions: They can help you deduct credit card interest accurately, even for complex cases like balance transfers or expenses spread across multiple accounts.
- Plan for Tax Changes: A professional ensures you’re compliant with new rules, like changes to what’s tax-deductible this tax year, and helps you minimize your taxable income.
- IRS Compliance: They guide you on handling unique scenarios, such as how annual interest or daily interest rates impact deductions.
3. Leverage Your Credit Card Issuer’s Tools
Most credit card companies now offer year-end summaries that break down your spending by category. These tools help you:
- Quickly identify business-related credit card charges.
- Spot eligible expenses that you can report during tax filing.
- Ensure compliance by matching the totals with your credit card statement to avoid mistakes.
By pairing QuickBooks, a trusted tax professional, and tools from your credit card issuer, you’ll simplify your tax preparation process, avoid errors, and ensure you’re maximizing your tax savings.

Common Mistakes Business Owners Make When Filing Credit Card Interest Deductions
What Happens if You Mix Personal and Business Purchases?
Mixing personal credit card charges with business expenses on the same credit card account creates confusion and risks for your tax filings. The IRS requires that you only write off credit card interest tied to tax-deductible business expenses. When you don’t separate these, here’s what can happen:
- If you carry a balance from month to month, your credit card interest becomes harder to allocate accurately.
- Mistakes in separating interest paid on credit for personal vs. business purchases could lead to rejected deductions.
- This misstep may even trigger IRS audits, potentially affecting your entire credit card bill.
Pro Tip: Open a dedicated credit card account with a card with a lower annual percentage rate (APR) for business expenses. Paying the balance in full every month helps you avoid paying interest, but if you must carry a balance, clear separation ensures your interest on a credit card is eligible for deductions.
Why Is It Important to Stay Updated on Tax Laws?
Tax laws can shift every tax year, affecting whether you can deduct credit card interest or how you calculate it. For example:
- The Tax Reform Act of 1986 eliminated deductions for personal credit card interest, requiring business owners to maintain clear boundaries.
- Changes in interest rates or adjustments to prime rate levels may influence the cost of credit card debt and your ability to claim deductions.
- IRS updates can also impact how you handle balance transfers, billing cycle details, or daily interest rate calculations when preparing to file your tax return.
If you don’t stay informed, you risk missing valuable deductions or making errors during tax preparation.
How to Stay Ahead:
- Review IRS publications every tax year to ensure compliance.
- Work with a tax advisor who can help you navigate changes and optimize your deductions come tax season.
- Use accounting software to track credit card interest and monitor your new balance from one billing cycle to the next.
By staying informed, you protect your business and ensure you’re making the most of every tax-deductible opportunity.
Key Takeaways
- Deductible Interest Applies Only to Business: The IRS allows deductions for credit card interest tied to business expenses, but you cannot deduct interest on personal purchases.
- Use a Business Card for Lower Interest: A credit card for business with a lower interest rate helps reduce costs if you carry a balance month to month, though paying the full each month is ideal.
- Understand How Credit Card Interest Works: Knowing how annual interest is calculated and how companies charge interest helps you manage costs and maximize deductions.
- Maintain Organized Records: Save credit reports, credit card statements, and receipts to accurately include your credit deductions during tax filing.
- Plan to Avoid Extra Costs: Paying the balance in full can also get free of interest, but if paying it off fully isn’t an option, a card with low annual interest is crucial to reduce financial strain.
