Referring a friend to an Amex card is one of those points-and-miles mechanics that sounds free and easy until you actually do the math. You log into your account, grab a personalized link, send it to your sister, and a few months later you have 15,000 Membership Rewards points sitting in your account. The catch is that "free" isn't quite right. Amex will eventually send you a 1099-MISC if you earn enough, the bonus you receive may not be the best deal your sister could have gotten on that card, and the public offer she sees on the open web is sometimes higher than what your referral link shows her. Here is how the program actually works in 2026, what you can earn, and when to skip it.

Quick Answer

Amex Refer-a-Friend pays the referrer a Membership Rewards or co-brand-points bonus when a friend applies through their personalized link and gets approved. Personal-card referrals typically pay 10,000 to 30,000 points each, capped around 55,000 points per card per calendar year. The bonus is reportable income, so Amex sends a 1099-MISC if your fair-market value crosses $600. Before you send the link, compare it against the public welcome offer and any targeted CardMatch offer your friend may have. The referral isn't always the best deal for them.

How the program works

You have to be an existing Amex cardholder to refer. You log into the Amex referral portal at americanexpress.com/refer, and Amex shows you the cards in your wallet that currently have an active referral offer, along with the bonus you would earn for each approved referral.

You can also refer for cards you do not personally hold. Amex calls this "view all cards with a referral offer." Your friend clicks your link, then picks any card on the eligible list. You still get the referrer bonus, even though that card is not in your wallet. This is the part most cardholders miss.

The referral link is personalized to you, so Amex tracks it back to your account. Your friend applies, gets approved, and after roughly 8 to 12 weeks the points post to your account. The lag is real. If your sister applies in January, do not expect to see the points until April at the earliest.

For your friend, the offer they see when they click your link might be:

  • Higher than the current public offer (referral is the better deal)
  • The same as the public offer (no difference)
  • Lower than the current public offer (referral is the worse deal)
  • Lower than a targeted CardMatch offer they could have pulled (referral is the worst deal)

Amex makes no promises that the referral offer matches or beats the public one. You have to check.

What you can actually earn

Bonus amounts shift through the year and vary by card. As of mid-2026, here are the rough ranges you should expect:

  • Amex Platinum (personal): 15,000 to 30,000 MR points per approved referral
  • Amex Gold: 10,000 to 20,000 MR points per approved referral
  • Hilton Honors Aspire and Surpass: 20,000 to 30,000 Hilton points
  • Marriott Bonvoy Brilliant: 20,000 Bonvoy points
  • Amex Blue Cash Preferred: typically a $75 to $200 statement credit, not points

The annual cap matters more than the per-referral number. For most personal Amex cards, you are limited to 55,000 Membership Rewards points per calendar year per card. Some co-brand cards run higher caps, sometimes 80,000 Hilton points. Co-brand caps reset January 1, same as the MR cap.

Here is the spending math in points-currency terms. If you refer three friends to the Amex Platinum at 20,000 MR each, you have earned 60,000 points, but the 55,000-point cap means Amex only credits you 55,000. The third referral does not "roll over." It just stops paying after you hit the ceiling. If you are within shouting distance of the cap, switch to referring for a different card so you start fresh on a separate cap.

A Membership Rewards point is worth roughly 1.5 to 2 cents when transferred to airline and hotel partners, and roughly 1 cent when redeemed for travel through the Amex portal. At a 1.8 cents-per-point valuation, a 20,000-point referral is worth about $360. A full 55,000-point cap year is worth around $990.

The tax piece nobody talks about

Referral bonuses are not treated like welcome bonuses. The IRS view, and Amex's view, is that you did not have to spend money to earn them. That makes them income, not a rebate. If the fair-market value of your referral bonuses crosses $600 in a calendar year, Amex sends you a 1099-MISC the following January.

The valuation Amex uses on the 1099 is generally 1 cent per Membership Rewards point, which is lower than what most people redeem at. That cuts both ways. The reported income is lower than the real value of the points to you, which is fine for your tax bill but worth knowing.

A worked example. You refer five friends to the Amex Gold at 15,000 MR each. That is 75,000 points, but the cap holds you at 55,000. At 1 cent per point, Amex reports $550 on your 1099, which is just under the threshold and may not generate a form. Refer one more friend, hit a 5,000-point bonus on a different card, and you cross $600. The 1099 gets generated.

This is income that flows to your Schedule 1, line 8z, "other income." Self-employed referrers should already be familiar. Salaried W-2 employees should not be surprised by a January envelope from American Express.

Referral offer vs. public offer vs. CardMatch

Before you send your link to a friend, run this sequence:

  1. Pull up the public welcome offer on the Amex card landing page (in an incognito window, so you are seeing the offer Amex shows to a non-logged-in visitor).
  2. Have your friend check the CardMatch tool at creditcards.com. Targeted offers are often higher than public offers, especially on the Amex Platinum.
  3. Click your own referral link, in an incognito window, and check what the referee sees on the landing page.

Whichever number is highest is the offer your friend should take. If the public offer is 80,000 MR points and your referral link shows 60,000 MR, your friend leaves 20,000 points on the table by using your link. The 20,000 points you earn as a referrer does not make up for what they lose.

One trap: applying through a referral link disqualifies the referee from a CardMatch offer on that same card, because the application is tied to your link, not to the targeted offer code. If your friend has a strong CardMatch hit, the right move is for them to apply directly through CardMatch and skip the referral entirely. You lose the bonus. They come out ahead.

This is the conversation worth having with the friend you are referring. Tell them to check CardMatch first. If your link is the best offer, send it. If not, do not push it.

How referrals interact with 5/24 and other rules

The 5/24 rule is a Chase guideline, not an Amex one, but it applies to your friend's overall application strategy. Opening an Amex card adds to their 5/24 count, which affects future Chase applications. The referral itself does not change 5/24 math, but the new card does. If your friend is at 4/24 and is targeting a Chase card later in the year, opening an Amex through your referral pushes them to 5/24 and likely blocks the Chase approval for the next two years.

For you, the referrer, the bonus does not affect your 5/24 count. You are not opening a new card. Your existing-cardholder relationship with Amex stays exactly where it was.

Two other rules to know:

  • Amex's once-per-lifetime welcome bonus rule. Your friend can only earn the welcome bonus on a given card product family once. If your sister had the Amex Platinum five years ago and closed it, she likely cannot earn the welcome bonus again, referral or not. Amex has a population-level exception process, but assume the rule holds.
  • Amex pop-up jail. If your friend has applied for too many Amex cards recently, they may see a pop-up at the end of the application saying they are not eligible for the welcome bonus. The referral link does not get them around this. If the pop-up shows, they should cancel the application.

Common mistakes

Sharing the link publicly without disclosing. If you tweet your referral link, FTC rules require you to disclose that you receive a bonus. "I'll get a bonus if you sign up" is enough. The legal exposure is small for individuals, but Amex can claw back referrals tied to spammy public sharing.

Not tracking which referrals are pending. Amex's portal shows pending and posted referrals, but the 8-to-12-week lag means you might forget who you referred. Keep a simple note: friend's name, date sent, card, expected bonus. When the 12-week mark passes without a credit, contact Amex.

Stacking referrals past the cap. If you have already earned 50,000 of your 55,000 MR cap on the Platinum, do not push a friend to apply for another Platinum referral. Switch them to a different card you can refer for, which has its own separate cap.

Assuming the referral offer is the best offer. Already covered above, but this is the single most common mistake. Check public and CardMatch first, every time.

Ignoring the 1099. If you have earned more than about 35,000 referral points in a year, you are in 1099 territory. Plan for it. The form will arrive in late January.

When not to use referrals

Skip the referral when your friend has a strong CardMatch offer for the card. Skip it when the public offer is higher than your link shows. Skip it when your friend is already in pop-up jail on Amex. Skip it when they are on a tight 5/24 budget and would be better served by a Chase card.

There is also a relationship case. Some people do not want a friend or family member earning a bonus off their credit card application, especially if the bonus structure isn't clearly explained. That is fair. Disclose, then let them decide. Pushing the referral past a friend's hesitation is a quick way to make a credit card recommendation feel transactional.

What I'd actually do

If you carry the Amex Platinum and the Gold and one or two Hilton cards, you have a meaningful referral pipeline. Here is the approach that works:

  1. Refer first for whatever card pays the highest current bonus, not whichever card you happen to hold. The "view all cards with a referral offer" option lets you refer for cards you don't carry.
  2. Always run the public-offer and CardMatch comparison before you send the link. Be willing to tell your friend, "do not use my link, here's a better offer." That builds trust and gets them to come back to you for the next card.
  3. Spread referrals across cards to avoid hitting one card's cap. Two friends on Platinum, two on Gold, one on Hilton spreads you across three caps instead of bumping into 55,000 on one card.
  4. Track referrals in a note. Check the portal monthly. Contact Amex if a referral doesn't post within 12 weeks of approval.
  5. Budget for the 1099. If you cross $600 in fair-market value, the income flows to your tax return. It is not enough to plan a quarter around, but enough to remember in April.

Amex Refer-a-Friend is a solid points-and-miles supplement for active cardholders. It is not a primary points strategy. The cap is too low and the comparison work is too involved for the program to be a major earner. But layered onto existing card spend and welcome bonuses, an extra 30,000 to 100,000 MR points a year is real value, especially when you transfer it to a partner at 1.8 cents per point.

The discipline is in the comparison, not the referral itself. Run the math each time, and the program pays off. Skip the math, and you'll occasionally cost your friends real points.
