The best business credit cards for sole proprietors let you apply with your SSN and personal credit, helping you separate expenses and build business credit. We picked the top cards for flat-rate cash back, travel rewards, and international use.
If you're a sole proprietor, you don't need an EIN or a formal business entity to get a business credit card. You can apply using your Social Security number, and issuers evaluate your personal credit history just like they would for a personal card.1
That's good news — because a dedicated business card is one of the simplest ways to keep your business and personal expenses separate. That separation makes tax time easier, helps you track deductible spending, and starts building a business credit profile that can unlock better financing down the road.2
Here are the three best business credit cards for sole proprietors, each suited to a different priority.
Sole proprietors who work with international clients, travel frequently, or deal in multiple currencies need a card that doesn't punish them with hidden exchange rate markups. The Wise Business card is built for this exact scenario.
You get real-time mid-market exchange rates on every transaction, with no foreign transaction fees and no annual fee. It connects to the Wise multi-currency account, so you can hold and manage balances in over 40 currencies. For a sole proprietor invoicing overseas clients or paying international contractors, this is the most transparent option available.
| Annual fee | $0 | | Reward type | No rewards — built for low-cost spending | | Key benefit | Real mid-market exchange rates, 40+ currencies |
If you don't want to track rotating categories or worry about which purchases earn bonus points, the Citi Double Cash is the simplest cash-back card you can carry. It earns 2% cash back on every purchase — 1% when you buy and 1% when you pay it off.1
For sole proprietors with varied monthly expenses — office supplies one month, software subscriptions the next, client lunches the month after — a flat-rate card means you never leave rewards on the table. There's no annual fee, and the cash back can be redeemed as a statement credit or deposited into a bank account.
| Annual fee | $0 | | Reward type | 2% flat cash back (1% + 1% on payment) | | Key benefit | No category tracking, no caps |
Sole proprietors who travel for client meetings, conferences, or site visits will get strong value from the Capital One Venture Rewards card. New cardholders earn 75,000 bonus miles after spending $4,000 in the first 3 months. You earn 2x miles on every purchase, plus 5x miles on hotels and rental cars booked through Capital One Travel.2
The miles transfer to over 15 travel loyalty programs, including Air Canada, British Airways, and Singapore Airlines — so you can often get more than 1 cent per mile in value. The card has a $95 annual fee (waived the first year), and it includes a Global Entry or TSA PreCheck credit.
| Annual fee | $95 (waived first year) | | Reward type | 2x miles on everything, 5x on travel booked through Capital One | | Key benefit | Transferable miles, Global Entry/TSA PreCheck credit |
| Wise Business | Citi Double Cash | Capital One Venture | |
|---|---|---|---|
| Annual fee | $0 | $0 | $95 (waived yr 1) |
| Reward rate | No rewards | 2% cash back | 2x miles |
| Best for | International use | Simple cash back | Travel rewards |
Easy application. Sole proprietors apply with their SSN and personal credit score — no EIN or business tax returns required. This makes the process nearly identical to applying for a personal card, but you get the benefits of a business account.1
Credit building. Many business card issuers report payment activity to business credit bureaus (Dun & Bradstreet, Experian Business, Equifax Business). Using a business card responsibly can help you establish a separate business credit profile, which may help you qualify for loans or better terms later.2
Expense management. A dedicated card means every business expense shows up in one place. At tax time, you can pull a year-end statement instead of combing through personal transactions. Most issuers also let you generate expense reports and set spending limits for employees (if you ever hire).1
No personal liability shield — but still worth it. It's important to note that a business credit card doesn't legally separate your personal and business liability the way an LLC or corporation does. Sole proprietors are personally responsible for the debt. But the organizational and credit-building benefits still make a dedicated card a smart move.2
