The new $300 annual ChatGPT credit for Amex business cardholders just came online today. If you hold the Amex Business Gold or Business Platinum, don't forget to enroll — and with a small bit of setup, you can stretch this credit much further than the obvious "subscribe and get $300 back" play.

What the Credit Covers

The credit reimburses ChatGPT Business subscriptions, up to $300 per calendar year per card, applied automatically when you pay with the enrolled Amex business card.

Two important quirks of ChatGPT Business pricing:

  • It requires at least two members. You can't run a single-seat ChatGPT Business plan.
  • Pricing is $50/month month-to-month, or $40/month billed annually — for two seats. A solo team plan does not exist.

That means the lowest "default" cost for two seats is $40/month × 12 = $480/year, which exceeds the $300 credit. Stick with the monthly $50/month plan and you're at $600/year — well above the cap. Either way, on retail pricing you're leaving money on the table.

The Promo Link Trick: $20/Month for 2 Seats

OpenAI runs partner discount links with select small businesses that drop ChatGPT Business to $20/month for two seats — and the price is guaranteed for 48 months. A bit of Googling around "ChatGPT Business promo code" will surface a handful of these partner URLs.

At $20/month, two seats cost $240/year — comfortably under the $300 credit cap, with room to spare.

Tax tip: Use a California zip code at checkout to avoid sales tax on the $20 subscription.

Why the $50 Plan Doesn't Work

If you opt for the standard month-to-month $50/month plan, you'll burn through the $300 credit in 6 months ($50 × 6 = $300) and pay out of pocket for the remaining half of the year. The annual $40/month plan locks you into $480 upfront — still over budget. The promo-link route at $20/month is the only path that keeps you entirely within the credit and doesn't lock you into annual prepayment.

Stacking Two Cards for a Free Year

Here's where it gets interesting. The credit is per card and resets each calendar year. If you hold both the Business Gold and Business Platinum, you have $600/year in combined ChatGPT credits to work with.

A clean strategy: pay with one card for the first six months, swap the payment method on your subscription to the second card for the back half of the year. That's effectively a free year of ChatGPT Business across both cards, plus headroom to add more seats.

The Math With 7 Months Left in 2026

Since we're now in May, there are roughly seven months left in the calendar year for these credits:

  • $300 / 7 months ≈ $42 of credit per month per card
  • At $20/month per 2-seat account, $42 covers about 2 accounts (4 seats) per card
  • Across both cards, that's 4 accounts and 8 seats before year-end

If you don't need that many seats yourself, ChatGPT Business plans can be useful to share with family, co-founders, or staff — each account stays separate and the credit only cares that the merchant code matches.

A Few Practical Notes

Enroll before charging. As with all Amex credits, you usually need to click "Enroll" on the benefit page in your Amex account before the credit will trigger. Don't assume it's automatic.

The credit is by calendar year, not card anniversary. Whatever you don't use by December 31 doesn't roll over.

ChatGPT Business vs Free/Plus. The business plan includes unlimited usage on the higher-tier models and centralized billing. If you've been on the $20/month ChatGPT Plus plan as an individual, this credit effectively pays for an upgrade to Business at the same out-of-pocket cost — but with a stronger model and unlimited usage.

Bottom Line

If you hold the Amex Business Gold or Business Platinum, this is one of the cleanest new credits Amex has rolled out in a while — it's recurring, it's on a product most people are already paying for, and with the promo-link discount it's genuinely free rather than just discounted. The combined $600 across both cards is more than enough for a full year of ChatGPT Business at promo pricing, with room for extra seats.

Enroll today, set up your subscription with one of the partner discount links, and circle back in six months to swap the payment method to your second card.
