The Business Platinum Card® from American Express ranks as our best small business card with luxury perks. The card offers over a dozen premium perks for business owners. Whether it's travel, purchase protection, rewards or expense management, there's a benefit for every type of business owner.

Cardholders earn a competitive 5X Membership Rewards® points on flights and prepaid hotels on Amextravel.com and 1X points on all other purchases. Plus, you earn 50% more points on purchases of $5,000 or more. Points redeemed for flights through Amex Travel get 35% points back, up to 500,000 bonus points per calendar year.

Luxury travel benefits include a statement credit for Global Entry or TSA PreCheck, access to over 1,200 airport lounges through the American Express Global Lounge Collection and an annual $200 airline fee credit for incidentals, like baggage and seat upgrades.

This card also comes with up to $200 in statement credits annually: Get up to $100 in statement credits between January and June and up to $100 in statement credits between July and December for U.S. purchases with Dell Technologies on your Business Platinum Card when enrolled.

While this card has a suite of benefits, it comes with a hefty $595 annual fee (see rates and fees). And each employee card costs an additional $300 annually. If you take advantage of all the card benefits, you can offset the high annual fee. You do have the option to open alternative employee cards for a lower fee: $200 for each additional Executive Business Card and $45 for each additional Business Gold Rewards Card.
