Is credit card interest tax deductible?

Yes — for interest properly tied to business purchases or business cash advances. A dedicated business-only card is simplest. A mixed personal/business revolving balance needs tracing over time; the deductible percentage is not necessarily the same as this month's percentage of new business charges.

Short answer

Business credit-card interest can be deductible. The interest must be allocated to debt created by business use. Personal interest remains personal even if it appears on a card marketed as a business card.

For Schedule C filers, deductible business credit-card interest generally goes on Line 16b under the latest finalized form.

Tracing rule: Interest follows the debt behind the balance

Credit-card interest follows the same general debt-allocation principle as other borrowing. What matters is the use that created the debt — business, personal, or investment — not the label printed on the card.

Dedicated business-only card: The simplest case

If the card is genuinely used only for your trade or business, the interest on that business balance is generally business interest. A consumer-branded card can still be business-only for tax tracing if you actually use it only for business purchases.

Mixed-use card: Do not use only this month's charge percentage

A mixed card with a revolving balance is more complicated than dividing this month's new business charges by this month's total charges. Interest can relate to older balances, and principal payments can change the remaining business/personal allocation.

Safer practical approach

  1. Identify the existing carried balance attributable to business vs personal uses.
  2. Add new business and personal charges or cash advances according to their actual use.
  3. Apply repayments under the debt-allocation rules and update the remaining balance.
  4. Allocate interest based on the resulting debt allocation rather than a simple annual or monthly new-charge ratio.

If the mixed revolving balance is material or complicated, a tax preparer can help maintain the allocation. The cleanest operational solution is keeping future business charges on a separate card.

Why repayments can change the deductible percentage

IRS allocation guidance shows that repayment of mixed-purpose debt can require the remaining debt to be reallocated. That means a card that started 60% business does not necessarily stay 60% business after personal purchases, business purchases, and principal payments occur at different times.

Illustrative balance change

Suppose a card balance begins as a mix of business and personal debt. A principal payment reduces the debt, then new business and personal charges are added. The resulting business percentage can differ from both the original balance percentage and the current month's new-charge percentage.

This is why the old shortcut “business charges ÷ total charges for the billing period” can misstate interest on an account that carries balances from earlier periods.

Credit card annual fees: Separate from interest

An annual fee is a service or bank fee, not interest. A fee that is ordinary and necessary for a business-only card can generally be a business expense. If the card serves both business and personal purposes, use a reasonable business-use allocation rather than treating the entire fee as business by default.

The latest finalized Schedule C no longer uses Line 27a for general Other Expenses. An ordinary business card fee not reported elsewhere is generally listed in Part V, Line 48, which flows to Line 27b on the current form.

Examples

Dedicated business-only card

A freelancer uses one card only for software, ads, supplies, and other business costs and carries a balance. Interest on that properly traced business balance is generally business interest.

Mixed revolving card

A card carries an older personal balance and then adds mostly business purchases this month. You should not multiply the full statement interest by this month's business-charge percentage, because the interest also relates to the older carried debt.

Business cash advance

A cash advance used entirely to pay a business supplier can create business debt; the same advance used for personal spending creates personal debt. Keep the transfer and payment records showing where the cash went.

FAQ

Is credit card interest tax deductible for business?

Generally yes to the extent the interest is properly allocated to debt created by business purchases or other business use. Personal charges create personal interest even on a card labeled as a business card.

Can I deduct interest on a personal credit card used for business?

Potentially yes. The card's label does not control the interest classification. If the balance is properly traced to business use, that portion can be business interest; mixed revolving balances require an allocation.

How do I allocate interest on a mixed business and personal card?

Do not rely only on this month's business charges divided by this month's total charges when the card carries a balance. Existing business and personal debt, new charges, and principal repayments can all change the allocation over time.

Is a business credit card annual fee tax deductible?

A card fee that is ordinary and necessary for business can generally be a business expense. It is not interest. On the latest finalized Schedule C, an ordinary fee not reported elsewhere is generally listed in Part V, Line 48, flowing to Line 27b; mixed-use fees should be reasonably allocated.

Where does business credit card interest go on Schedule C?

Deductible business credit-card interest generally goes on Line 16b. Card annual or service fees are separate from interest and generally belong in Other Expenses when not reported elsewhere.
