Is credit card interest tax deductible?
It depends. Credit card interest may be deductible when the card is used for business expenses. If the card is mixed-use, only the business portion of interest is typically deductible.

Short answer
Depends. Credit card interest is tax deductible only to the extent the interest relates to business or income-producing purchases. Interest on personal spending is generally not deductible.
The easiest way to support a deduction is to use a dedicated business card and keep clean records.
When it’s more likely deductible
- The credit card is used exclusively for business purchases
- You can tie charges to deductible business expenses (software, supplies, travel, etc.)
- You keep statements showing interest and payments
- You have a reasonable allocation method for any mixed-use period
When it’s not deductible (or risky)
- The interest relates to personal purchases
- The card is heavily mixed-use and you can’t allocate interest
- You don’t keep statements showing interest charged
- You’re trying to deduct interest without showing business purpose for the underlying charges
Example
A freelancer uses a credit card only for business expenses like software subscriptions and advertising. If they carry a balance and pay interest, the interest is generally deductible as a business expense.
If they also use the card for personal spending, they should allocate interest and deduct only the business portion.
What records to keep
- Monthly credit card statements showing interest charged
- Receipts/invoices for business purchases made on the card
- Notes or tagging that identifies which charges were business
- An allocation worksheet if the card is mixed-use
FAQ
Do I need a business credit card to deduct interest?
No, but it helps. You can sometimes deduct interest on a personal card if the charges are business-related and well documented.
How do I allocate interest on a mixed-use credit card?
A common approach is to track business vs personal charges and allocate interest proportionally. The key is to be consistent and keep records.
Is interest deductible if I pay the balance in full each month?
If you pay in full, you typically won’t have interest to deduct. In that case, your deduction is the underlying business expenses charged to the card.
