QUICK ANSWER
The best business credit cards for rewards and cash back in 2026 are the Chase Ink Business Cash, American Express Blue Business Cash, Capital One Spark Cash Plus, Bank of America Business Advantage Unlimited Cash Rewards, and the Brex Card. The right card depends on your primary business spending categories (office supplies, advertising, travel, or general spend), your preferred reward type (cash back vs. travel points), and whether you want a charge card with no preset limit or a revolving credit card.
Key Takeaways
- Business credit cards separate business and personal expenses automatically — using a dedicated business credit card for all business spending creates a clean transaction record that makes bookkeeping significantly easier and protects the liability separation of your LLC or corporation.
- Rewards on business cards aren’t taxable income — cash back and points earned on business credit card spending are considered a rebate on business purchases, not taxable income; however, the purchase amount you record as a business expense should be reduced by any rewards received for that specific purchase.
- Employee cards with spending limits help control costs and track department expenses — most business credit cards allow free employee cards with individual spending limits and transaction-level reporting, making it easy to give team members purchasing power without losing control of spend.
- Sign-up bonuses can be worth $500–$1,500 on business cards — business credit card welcome offers are typically larger than personal card offers; the spending requirement to earn the bonus is also usually higher, but businesses that can hit the threshold in normal spending should prioritize sign-up bonus optimization.
Best Business Credit Cards for Rewards in 2026
1. Chase Ink Business Cash — Best for Office Spending Categories
The Chase Ink Business Cash earns 5% cash back on the first $25,000 spent annually at office supply stores and on internet, cable, and phone services — categories that represent significant monthly expenses for most small businesses. It earns 2% on the first $25,000 at gas stations and restaurants, and 1% on everything else. There’s no annual fee. The welcome bonus is currently $750 cash back after spending $6,000 in the first 3 months — one of the strongest no-annual-fee business card offers available.
The Ink Business Cash works particularly well for businesses with high telecom, internet, and software subscription spending (which often codes as “office supply stores” on many platforms). For businesses that route significant software subscriptions through office supply stores, the 5% category can generate substantial annual rewards.
2. American Express Blue Business Cash — Best Flat-Rate Cash Back
The Amex Blue Business Cash earns 2% cash back on all eligible purchases up to $50,000 per year (then 1%) with no annual fee. For businesses with diverse spending that doesn’t concentrate in bonus categories, the Amex Blue Business Cash’s flat 2% rate is often more valuable than cards that earn high rates in specific categories but 1% on general spending. Amex’s purchase protection, extended warranty, and business management tools are included benefits.
3. Capital One Spark Cash Plus — Best for High-Volume Spending
The Capital One Spark Cash Plus (charge card, no preset limit) earns 2% cash back on all purchases with no category restrictions and no spending cap — making it the best choice for businesses with very high monthly spend where the Amex Blue Business Cash’s $50,000 cap becomes limiting. There’s a $150 annual fee, but Capital One rebates the fee when your annual spending exceeds $150,000. For businesses spending $200K+ annually on the card, the Spark Cash Plus’s uncapped 2% generates $4,000+ in annual cash back minus the $150 fee.

Frequently Asked Questions
How do business credit card rewards affect my taxes?
Cash back rewards on business credit cards are generally treated as a rebate that reduces the deductible cost of the purchases you made — they’re not treated as taxable income. Practically, this means: if you deduct $10,000 in office supply purchases that earned $200 in cash back, your deductible expense should technically be $9,800 (the net cost after rebate). Many small business owners don’t adjust their expense deductions for cash back, which is technically incorrect but rarely material enough to trigger scrutiny. Sign-up bonuses earned for meeting a spending threshold are similarly treated as rebates, not income. Consult your CPA for the treatment specific to your situation.
