What is Business Credit Card Interest?

In very simple terms, business credit card interest is the cost you pay for borrowing money when you carry a balance on a business credit card. Usually, this interest is calculated as an Annual Percentage Rate (APR) and charged monthly if your balance is not paid in full. 

• The interest charges may apply to:
  • Your monthly carried balances. 
  • Cash Advances from credit card.
  • On Certain Transaction Fees. 

The IRS classifies interest as a financing expense, not a purchase. Apart from this, that distinction is important because financing costs for business operations are usually deductible.

What Does The IRS Law Say?

The Internal Revenue Service (IRS) states that interest paid on money borrowed for business purposes is typically deductible as a business expense. This rule clearly applies to 

• The Loans.
• Lines of Credit.
• And the business credit cards. 

Moreover, there is no Internal Revenue Service (IRS) rule that disallows business credit card interest deductions. But the main requirement is that the debt must be directly related to the business activity.

When Business Credit Card Interest is Tax Deductible

Some conditions are required to be satisfied for business credit card interest to be deductible : 

1. The Expenses Must be Necessary and Ordinary

The IRS only allows deductions for expenses that are : 

• Ordinary – The costs are common in your industry. 
• Necessary – The costs are helpful and appropriate for your business. 

Examples

• Your office supplies and equipment.
• Inventory and materials.
• The software tools and subscriptions. 
• The marketing and advertising. 
• Your professional services, like legal, accounting, and all. 
• Your business travel and lodging. 

If your interest arises from paying these expenses, it is generally deductible. 

2. A Credit Card is Used For Business purposes

• If you use a business credit card only for business, the interest is fully deductible as per IRS law. 
• However, if you use the card for both business and personal expenses, only the business portion of the interest can be deducted. 

This distinction is very important during IRS audits. 

3. You Are Legally Responsible for the Debt

Most business credit cards generally require a personal guarantee, especially for small businesses and startups. Typically, this doesn’t eliminate the deduction : 

• As long as :
  • The expenses are from your business-related expenses. 
  • The interest is paid. 

These deductions generally apply. 

When Business Credit Card Interest Is Not Deductible?

There are clever situations where business credit card interest can not be deducted. Situations are mentioned below : 

1. Interest On Personal Expenses

The interest related to your personal spending is never deductible, even if the charges are on a business credit card. 

• Example
  • Spending on Groceries.
  • Personal rent or mortgage.
  • Personal Vacations.
  • The entertainment is unrelated to the business. 

The charging of personal expenses to a business credit card creates tax and accounting problems. 

2. Poorly Tracked Mixed-Use Cards

If a credit card is used for both business and personal expenses without any clear records, the IRS may : 

• Disallow the part of the deduction.
• Or reject the entire deduction. 

This is a very common mistake that most small business owners make.

3. Non-Deductible or Illegal Activities

• The interest related to :
  • Fines or Penalties.
  • Illegal Transactions. 

They are not deductible, regardless of payment method.
