How to Use the Business Card Expense Deduction Calculator
Note: the U.S. has no federal value-added tax (VAT). In countries like Korea, business owners reclaim the VAT embedded in a purchase price as an "input tax credit," which directly reduces what they owe the government. There's no equivalent mechanism at the federal level in the U.S. Instead, when you use a business credit card for a qualifying purchase, the full expense is deducted from your taxable income as an ordinary business expense on Schedule C (or the equivalent for your entity type) — lowering your income tax bill rather than refunding embedded tax.
Enter your total qualifying business card spending and your estimated marginal tax rate (federal plus state combined is a reasonable estimate), and this calculator shows the deductible amount and the actual cash value of the tax savings — spend multiplied by your marginal rate.
Not every charge qualifies: the expense must be "ordinary and necessary" for your business, some categories like business meals are only 50% deductible, and any personal spending mixed onto a business card doesn't count. This tool assumes the amount you enter is already fully qualifying business expense — for mixed or partial-business purchases, adjust the input accordingly before calculating.
Frequently Asked Questions
Because the U.S. has no federal value-added tax. In VAT countries like Korea, businesses reclaim the tax embedded in a purchase price directly.

No — the expense must be ordinary and necessary for your business. Some categories, like meals, are only 50% deductible, and personal spending on a business card never qualifies. This calculator assumes the amount you enter is already fully qualifying.
Not quite — a deduction reduces your taxable income, so the actual cash benefit equals the expense multiplied by your marginal tax rate, not the full expense amount. That's different from a direct tax credit or a VAT refund, which return money dollar-for-dollar.
