You can buy anything with your business credit card and deduct it, as long as the purchase is an ordinary and necessary expense of running your trade or business. “Ordinary” means the cost is common and accepted in your industry. “Necessary” means it is helpful and appropriate for the work. That single standard governs office supplies, marketing, travel, equipment, and everything in between. The harder question is not what you’re allowed to charge, but what the IRS will accept as a deduction when you file, and where the specific caps and exclusions kick in.
Everyday Operating Costs
Routine spending makes up most card activity for a typical business, and most of it is fully deductible in the year you pay. Paper, ink, postage, cleaning supplies, and similar consumables come off your income as soon as you use them. Utility bills for a business location, including electricity, internet, and water, belong on the card. So do recurring software subscriptions like accounting platforms, cloud storage, and project management tools.
Advertising is one of the cleanest deductions in the code. Search engine campaigns, social media ads, print materials, website design, and trade publication placements all qualify at full cost. The IRS draws no line between digital and traditional advertising.
Professional service fees are deductible when they relate to operating or protecting the business. That covers legal consultations, tax preparation, and accounting work. Dues to professional associations and local chambers of commerce also qualify. One boundary: dues to clubs organized primarily for recreation or social purposes are never deductible, no matter how much business networking happens there.1Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses
Continuing education is deductible when it maintains or improves skills you already use in your current work. Industry workshops, certification renewals, and courses on new developments in your field qualify. Education that trains you for a new trade or profession does not, even if it would also help your current business.2Internal Revenue Service. Publication 970 (2025), Tax Benefits for Education – Section: Business Deduction for Work-Related Education
Business Meals and the Entertainment Exclusion
Business meals are deductible at 50% of the cost. To claim them, the meal must have a clear business purpose, cannot be lavish or extravagant under the circumstances, and you or an employee must be present when the food is served.1Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses
Entertainment is a separate category, and the Tax Cuts and Jobs Act eliminated the deduction entirely. Concert tickets, sporting events, golf outings, theater, and similar activities do not qualify, even when business is discussed. If you buy food at an entertainment venue, you can still deduct 50% of the food cost, but only if it is invoiced separately from the entertainment or broken out on its own line of the receipt.
One shift catches employers off guard in 2026: meals provided to employees for the convenience of the employer, such as on-site cafeteria meals or food during mandatory overtime, are now fully nondeductible. Before 2026, those meals were 50% deductible.
Travel, Lodging, and Vehicles
Business travel is deductible when you are away from your tax home, meaning your duties keep you gone substantially longer than a normal workday and you need to stop for sleep or rest. Airfare, train tickets, hotel rooms, rental cars, baggage fees, and tips all qualify for the card.3Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses – Section: Travel
Lodging has to be reasonable for the circumstances. The IRS sets no fixed dollar cap but will disallow costs it considers lavish or extravagant. If you mix personal time into a business trip, only the expenses tied to the business portion are deductible. On a trip that is primarily business with a few personal days added on, you can still deduct the round-trip transportation to the destination, but not the extra hotel nights or meals from the personal side.4Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses – Section: Trip Primarily for Business
Vehicle Costs
For business driving, you have two methods: deduct actual vehicle expenses like gas, insurance, repairs, and depreciation, or use the IRS standard mileage rate. For 2026, that rate is 72.5 cents per mile.5Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents per Mile Fuel, tolls, and parking for business trips can go on the card regardless of the method you choose.
Commuting is not deductible. The drive from your home to your regular place of business is a personal cost no matter how far it is, even if you take calls along the way. Driving between work locations during the day is deductible local transportation. If your home qualifies as your principal place of business, driving from your home office to a client site or second location is also deductible.6Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses – Section: Transportation Expenses
Equipment, Furniture, and Inventory
Laptops, printers, machinery, and office furniture are capital assets. Instead of depreciating them over several years, most businesses can write off the full cost in the year of purchase using Section 179 or bonus depreciation. For 2026, the Section 179 deduction lets you expense up to $2,560,000 of qualifying equipment, with the deduction phasing out dollar-for-dollar once total qualifying purchases exceed $4,090,000.7Internal Revenue Service. Depreciation Expense Helps Business Owners Keep More Money Bonus depreciation under Section 168(k) has been restored to 100% for qualifying property acquired after January 19, 2025, so eligible assets placed in service during 2026 can be fully expensed the first year.8Internal Revenue Service. Notice 2026-11, Interim Guidance on Additional First Year Depreciation Deduction
The basis of a purchased asset, which is the figure you depreciate or expense, includes the purchase price plus sales tax, freight, and installation. Card statements help track the total, but hold the itemized receipt showing each component.9Internal Revenue Service. Publication 551 (12/2025), Basis of Assets – Section: Cost Basis
Inventory purchased for resale follows a different rule. Those costs are not deducted upfront but recovered through cost of goods sold as the inventory actually sells.
Business Gifts
Gifts to clients, vendors, or referral sources are deductible, but the IRS caps the deduction at $25 per recipient per year. That limit has never been adjusted for inflation. A $75 gift basket is a legitimate business expense to charge to the card, but only $25 of it reduces your taxable income.10eCFR. 26 CFR 1.274-3 – Disallowance of Deduction for Gifts
Incidental costs like engraving, gift wrapping, and shipping do not count against the $25 cap. Items costing $4 or less that carry your business name, such as branded pens or calendars, are treated as advertising rather than gifts and are not subject to the limit at all.
Purchases You Cannot Deduct
Some categories are permanently off-limits, whatever their connection to your business. Charging them to a business card is not illegal, but claiming them on your return is wrong and will draw adjustments if the IRS reviews your filing.
- Political contributions to candidates, parties, PACs, and political fundraising events.11Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses
- Lobbying expenses aimed at influencing legislation or executive branch officials. If you pay dues to a trade association that lobbies, the group must tell you what portion of your dues went to lobbying, and that portion is not deductible.11Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses
- Government fines and penalties, including parking tickets on company vehicles, OSHA fines, and regulatory penalties.
- Entertainment activities like sporting events, concerts, and theater, even when clients are present.1Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses
- Dues to social, athletic, or sporting clubs, even if you use them mainly for business meetings.
Personal Purchases on a Business Card
Mixing personal spending into a business card is where owners get into real trouble, and the consequences depend on your entity.
For sole proprietors, personal expenses paid from business funds are not deductible, and the income used to cover them still counts as gross business income. A grocery run does not become a business cost just because it hit the business statement.12Internal Revenue Service. Income and Expenses
For S corporation and C corporation owners, the stakes are higher. Courts have repeatedly ruled that when shareholders use corporate accounts to pay personal expenses, the payments get reclassified as wages or taxable distributions. The IRS has successfully argued in several cases that personal spending through company accounts amounted to disguised compensation subject to employment taxes, even when the shareholder called it a loan or a distribution.13Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers Routine mixing also weakens the legal separation between owner and entity, which can expose personal assets in a lawsuit.
An accidental personal charge is not a crisis. Reimburse the business promptly and document the repayment. A pattern of personal spending is what draws scrutiny.
Interest, Annual Fees, and Rewards
Interest on a business card balance is deductible because it is the cost of borrowing money for business purposes. Most small businesses get the full deduction. Larger businesses with average annual gross receipts above roughly $31 million over the prior three years face a cap under Section 163(j), which limits the business interest deduction to 30% of adjusted taxable income plus business interest income, with disallowed amounts carried forward.14Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense
Annual fees are deductible as an ordinary cost of maintaining a line of credit for the business. If you use the card exclusively for business, deduct the full fee. If you occasionally charge personal items to it, allocate the fee proportionally.
Cash-back rewards and points earned from business spending are generally not taxable. The IRS treats them as a rebate on the purchase price rather than new income. A private letter ruling confirmed that cash-back amounts adjust the purchase price and do not count as gross income.15Internal Revenue Service. Private Letter Ruling PLR-141607-09 Earning 2% back on $50,000 of purchases does not add $1,000 to your taxable income. A sign-up bonus that is not tied to purchases is different, because there is no purchase price to adjust, and the IRS could treat it as taxable.
Recordkeeping That Protects Every Deduction
A card statement by itself is not proof of a deduction. The IRS requires supporting documentation for every business purchase, and the burden falls on you. For each transaction, you should be able to show the amount, the date, the payee, and the business purpose.16Internal Revenue Service. What Kind of Records Should I Keep – Section: Supporting Business Documents
Travel, meals, and gifts get stricter treatment. You need to document the business relationship of the person you traveled with, dined with, or gave a gift to, along with the specific purpose.17Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses A receipt reading “$127 steakhouse” will not survive an audit. A note saying “$127 dinner with Jane Doe, ABC Corp, discussing Q3 supply contract” will.
Keep original receipts or organized digital copies. Statements, invoices, and receipts together form the paper trail the IRS accepts. If you cannot substantiate a deduction and it gets disallowed, you face an accuracy-related penalty of 20% of the resulting tax underpayment, on top of the tax itself.18Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments
When Employees Carry the Card
If employees have company cards, the business needs a written policy that meets the IRS definition of an accountable plan. Under such a plan, employee card charges are not taxable income to the employee, provided three conditions hold: the expense has a business connection, the employee substantiates it with adequate records within a reasonable time, and any amount charged beyond the substantiated business expense is returned to the employer.19eCFR. 26 CFR 1.62-2 – Reimbursements and Other Expense Allowance Arrangements
Fail any of those, and the plan is nonaccountable. Reimbursements and card charges become taxable wages on the employee’s W-2, subject to income tax withholding, Social Security, and Medicare. The same result applies if an employee makes personal purchases on a company card and the business does not require repayment.20Internal Revenue Service.
