Referring friends and family to credit cards is a straightforward way to earn extra rewards points. But what happens when someone needs a business card, and you only have personal ones? The answer isn’t always simple; referral rules vary significantly by issuer. Here’s a breakdown of how major banks handle cross-account referrals.

American Express: The Most Flexible Option

American Express stands out as the most accommodating issuer. You can earn referral bonuses whether your friend applies for a personal or business card using your referral link. To get started, log into your Amex account and click the “Refer Now” button at the bottom of the homepage.

The system initially displays cards linked to your current account, but recipients can navigate to “Business Cards” to explore all available options. Applying through this page still triggers your bonus, regardless of the final card choice. However, cobranded Amex cards (like Marriott or Hilton) generally restrict referrals within their own family.

Chase: Strict Family Rules with Some Exceptions

Chase is more restrictive. Typically, you must hold a card within the same family to generate a referral link. For example, if you have a Chase Freedom Flex, you can only refer someone to another Chase Freedom card.

To refer someone for an Ink Business card, you must already hold an Ink card. The same applies to the Chase Sapphire Reserve for Business. However, Chase’s cobranded cards (IHG, United, Southwest) offer slightly more flexibility, allowing referrals within the entire family, including business versions.

Capital One: Targeted Availability and Limited Cross-Use

Capital One appears to offer its refer-a-friend program selectively. If eligible, you’ll find referral links under “Rewards & benefits” on your card’s page. Generally, personal links work only for personal cards, and business links only for business cards. The system may not display all available cards to your referral, even if they exist. Notably, Capital One may not award a bonus if the applicant already has an existing account.

Citi: The Least Flexible System

Citi is the most rigid. Referral bonuses are often targeted, and cross-account referrals (personal to business) are generally not permitted. If you have a personal Citi card, you can’t refer someone to a business one.

The key takeaway is that issuers don’t want to reward you for referring someone to a card you don’t personally use. The goal is to encourage cardholders to bring in new customers within their ecosystem.

Maximizing Referral Opportunities

Referral programs are a simple way to earn extra rewards. But understanding each issuer’s rules is essential to maximizing your earnings. American Express offers the most flexibility, while Chase and Citi impose stricter limitations. Always double-check the terms before sharing a link to avoid disappointment.
