TL;DR

The Blue Business Cash is Amex’s flagship no-fee business credit card: 2% cashback on the first $50,000 per calendar year (1% thereafter), 12-month 0% intro APR, and no annual fee. For most small businesses with under $50,000 annual card spend, the effective rewards rate is a clean 2% with no category management. The 12-month 0% intro APR is among the longer business intro offers and applies to both purchases and balance transfers (in the 60-day intro window).

Math worked example with tax deductibility

$7,500 business balance at 22.49% APR (midpoint of range), $300 per month payment:

• Before tax: 30 months to payoff, $1,790 interest, total cost $9,290
• After-tax at 21% federal corporate rate (C-corp): effective interest cost $1,414, total after-tax cost $8,914
• After-tax at 24% federal marginal rate (typical small-business owner middle bracket): effective interest cost $1,360, total after-tax cost $8,860
• After-tax at 37% top marginal rate: effective interest cost $1,128, total after-tax cost $8,628

Per SBA financing guidance, business interest paid in the regular course of operations is deductible as an ordinary expense under IRC 162. The deduction is taken on Schedule C (sole prop), Form 1065 (partnership), 1120-S (S-corp), or 1120 (C-corp).

Run your specific Blue Business Cash numbers

The pillar tool accepts the Blue Business Cash purchase APR. Enter your specific rate from your most recent Amex business statement (under “Purchase APR”). The card has no annual fee, so total carrying cost is interest plus principal only.

0% intro APR math: the 12-month window

The Blue Business Cash offers 0% intro APR on purchases and balance transfers for 12 months from account opening. For a new account:

• Purchase scenario: $10,000 in business equipment purchase, paid $834 per month for 12 months: full payoff, $0 interest, total cost $10,000
• Balance transfer scenario: $7,500 transferred from another card (3% fee = $225 upfront): paid $625 per month for 12 months, total cost $7,725 (savings of ~$1,790 vs carrying at 22.49% on the original card)

If you cannot clear the full balance in 12 months, the residual hits the standard 18.49-26.49% APR on cycle 13. Set autopay to the pay-to-zero monthly amount, not the minimum.

Why business credit cards report differently

The Blue Business Cash reports to commercial credit bureaus (Dun and Bradstreet, Experian Business, Equifax Business) monthly. Personal credit bureaus (TransUnion, Equifax Consumer, Experian Consumer) are typically not reported unless the account is severely delinquent (90-plus days). The principal’s personal credit was pulled at application (hard inquiry), and personal guarantee means principal liability on default, with personal credit consequences once severely delinquent.

Avalanche priority for business debt

If you carry balances on both business and personal cards, the avalanche method still applies: pay extra on the highest-APR card first, minimums on the rest. Business interest deductibility slightly favors retaining business debt over personal debt at equal pre-tax APRs; a 22% business card at 24% marginal rate is 16.72% after-tax, compared to a 22% personal card at 22% after-tax. Pay the personal card first when pre-tax APRs are tied.

The 2% / 1% earning structure: when does the $50,000 cap matter?

For a business spending $50,000 a year on the Blue Business Cash: $1,000 cashback at 2%. For a business spending $100,000 a year: first $50,000 at 2% ($1,000), next $50,000 at 1% ($500), total $1,500.

Compare to the BoA Business Advantage Unlimited Cash Rewards: flat 1.5% with no cap. At $50,000 spend: $750 (Blue wins by $250). At $100,000 spend: $1,500 (tied). At $200,000 spend: $3,000 (BoA wins by $500 since Blue’s 1% above-cap underperforms BoA’s 1.5%).

The crossover point is $100,000 annual spend. Above that, the BoA Business Advantage Unlimited Cash (or Capital One Spark Cash at 2% flat with $95 fee) wins.

Balance transfer math: 12-cycle 0% intro

The 12-cycle 0% intro APR is competitive vs other business cards (BoA Business Advantage is 9 cycles, U.S. Bank Business Triple Cash is 15 cycles). For a $7,500 transfer:

• 3% transfer fee: $225 upfront
• Pay-to-zero in 12 cycles: $625 per month
• Total cost in 12 cycles: $7,725

Compared to carrying at 22.49% on the original card ($1,790 interest over 30 months at $300 per month), the Blue Business Cash transfer saves $1,565. Set autopay at the pay-to-zero amount; do not rely on minimum payments during the intro window.

Amex’s “once per lifetime” rule on welcome offers

Amex applies a “once per lifetime” rule per card product on welcome bonuses. If you previously held a Blue Business Cash and received the welcome bonus, you are not eligible for the bonus again on a new application. This applies to all Amex consumer and business cards. Unlike Chase’s 5/24 rule, Amex does not cap the total number of card products you can hold, but does cap welcome bonus eligibility.

Should you keep this card during payoff?

Yes. No annual fee, no holding cost. The 2% cashback continues to earn on whatever modest business spending you maintain during payoff. Keep open at zero balance after payoff to preserve available credit and account history.

When to consider an SBA-backed alternative

Per SBA financing guidance, business credit cards are best used for 30-60 day working-capital float. For sustained working-capital needs above $25,000 carried 12-plus months, an SBA Express line of credit (up to $500,000, single-digit APRs as of Q1 2026) is structurally cheaper than any business credit card, even after interest deductibility. The transition is to consolidate revolving business card debt with an SBA term loan or line of credit.

Frequently asked questions

What is the APR on the Amex Blue Business Cash?

The variable Purchase APR is 18.49-26.49% as of May 13, 2026 per the Amex Blue Business Cash pricing page. Your specific rate was set at application based on the principal’s credit profile and the prime rate published by the Federal Reserve H.15 release. The card offers a 12-billing-cycle 0% intro APR on purchases and on balance transfers initiated within 60 days of account opening. Check your business statement under “Purchase APR” for your specific rate.

Is the Blue Business Cash a credit card or a charge card?

It is a revolving credit card, not a charge card. Unlike Amex’s consumer Platinum, Gold, and Green (which are charge cards with Pay Over Time installment features), the Blue Business Cash allows you to carry a balance month-to-month at the published APR. This is a structural difference from the rest of the Amex lineup and makes the Blue Business Cash a more conventional credit-card product. Statement balance can revolve; minimum payment is 1% plus interest plus fees, $40 minimum.

How does the 2% cashback cap work?

You earn 2% cashback on the first $50,000 in purchases per calendar year, then 1% on purchases above the cap until the cap resets January 1. The cap is per calendar year, not per card anniversary. For a business spending $50,000 or less per year on the card, the effective rate is a clean 2%. For high-spend businesses ($100,000-plus per year), the BoA Business Advantage Unlimited Cash Rewards (flat 1.5% with no cap) or Capital One Spark Cash (2% flat with $95 fee) deliver more total cashback.

Is business credit card interest tax-deductible?

Yes, interest on business credit cards used for ordinary and necessary business expenses is deductible under IRC 162 as a business expense. Sole proprietors deduct on Schedule C; partnerships, S-corps, and C-corps deduct on their respective business returns per IRS Publication 535. The effective after-tax cost of business interest is reduced by your applicable marginal tax rate. Personal-use charges on a business card are not deductible; keep clean separation. Consult your CPA.

What credit score do I need for the Blue Business Cash?

Amex typically requires a personal FICO score of 670 or higher for the business principal applicant. The card is available to LLCs, sole proprietorships, partnerships, and corporations. Amex applies its “once per lifetime” rule on welcome offers per card product, so if you previously held the Blue Business Cash and received the welcome bonus, you are ineligible for the bonus on a new application. Amex does not have a 5/24 rule like Chase, but tracks total Amex card holdings across the family.
