On June 29, 2011, thousands of independent web publishers, software bloggers, and digital agencies across California received an immediate contract termination notice from the Amazon Associates Program. Hours after Governor Jerry Brown signed Assembly Bill 28X (AB 28X)—California's "click-through nexus" sales tax legislation—Amazon severed its affiliate relationships with roughly 10,000 to 25,000 California-based publishers to avoid triggering mandatory state sales tax collection.

Below is the verbatim email dispatched by the Amazon Associates team to all California residents on the afternoon the legislation was enacted:
Hello,
Unfortunately, Governor Brown has signed into law the bill that we emailed you about earlier today. As a result of this, contracts with all California residents participating in the Amazon Associates Program are terminated effective today, June 29, 2011. Those California residents will no longer receive advertising fees for sales referred to Amazon, Endless, MYHABIT, or SmallParts. Please be assured that all qualifying advertising fees earned before today will be processed and paid in full in accordance with the regular payment schedule.
You are receiving this email because our records indicate that you are a resident of California. If you are not currently a resident of California, or if you are relocating to another state in the near future, you can manage the details of your Associates account settings. And if you relocate to another state in the near future please contact us for reinstatement into the Amazon Associates Program.
To avoid confusion, we would like to clarify that this development will only impact our ability to offer the Associates Program to California residents and will not affect your ability to purchase from Amazon properties.
We have enjoyed working with you and other California-based participants in the Amazon Associates Program and, if this situation is rectified, would very much welcome the opportunity to re-open our Associates Program to California residents.
Regards,
The Amazon Associates Team
Why Did California Enact the Click-Through Nexus Tax?
To understand why affiliate publishers were caught in the crossfire between Sacramento lawmakers and Seattle e-commerce executives, we have to examine the constitutional tax framework that governed online retail prior to 2018:
- The 1992 Quill Corp. v. North Dakota Precedent: Under the U.S. Supreme Court's Quill ruling, states could only compel an out-of-state retailer to collect sales tax if that business maintained a substantial physical presence (such as brick-and-mortar storefronts, warehouses, or sales representatives) inside the taxing state.
- California Assembly Bill 28X (2011): Facing a severe state budget deficit, California lawmakers expanded the legal definition of "physical presence" to include click-through affiliate nexus. Under AB 28X, any out-of-state e-commerce merchant paying commissions to California-based affiliate websites was deemed to have an in-state sales force, obligating the retailer to collect California sales tax on all state orders.
- Amazon's Defensive Termination: Just as it had previously done in New York, North Carolina, Illinois, and Connecticut, Amazon immediately terminated its in-state affiliate contracts on June 29, 2011, eliminating the statutory nexus trigger overnight.
The 2012 Resolution: AB 155 and Affiliate Reinstatement
Following months of intense lobbying and a threatened statewide ballot referendum, California lawmakers and Amazon reached a historic compromise under Assembly Bill 155 (AB 155) in September 2011:
- One-Year Tax Collection Deferral: California agreed to postpone enforcement of the sales tax collection mandate until September 15, 2012, while Amazon committed to investing $500 million in California fulfillment centers and creating 10,000 full-time jobs across the state.
- Immediate Reinstatement of California Publishers: Because the statutory trigger was suspended by AB 155, Amazon officially reopened the Amazon Associates Program to all California publishers in September 2011.
- The 2018 South Dakota v. Wayfair Endgame: Seven years later, the U.S. Supreme Court overturned Quill entirely in South Dakota v. Wayfair, Inc. (2018), establishing that economic volume alone ($100,000 in annual sales or 200 transactions) creates sales tax nexus regardless of physical presence or affiliate partnerships.
Architectural Lessons for Affiliate Publishers
For California webmasters who saw their commission streams vanish overnight on June 29, 2011, the incident remains a textbook case study in platform risk and monetization architecture:
- Decouple Outbound Links via Internal Redirect Routers: Never hardcode hundreds of raw
amazon.com/?tag=...URLs inside static article HTML. Route outbound product links through a centralized server-side redirect endpoint (e.g.,/go/product-slug) backed by a database table so links can be repointed to alternative merchants (B&H Photo, Newegg, eBay Partner Network, or CJ Affiliate) in seconds. - Diversify Revenue Across Multiple Networks: Relying 100% on a single merchant's affiliate program exposes publishers to unilateral commission cuts and legislative disruptions.
Frequently Asked Questions
What happened to unpaid affiliate earnings accrued before June 29, 2011?
All qualifying advertising fees earned prior to the June 29, 2011 termination date were processed and paid out in full on Amazon's standard 60-day payment schedule.
Can California residents participate in the Amazon Associates Program today?
Yes. Following the enactment of California AB 155 and Amazon's transition to collecting California state sales tax in September 2012, California residents and businesses have been fully eligible to participate in the Amazon Associates Program without restriction.
Did the 2011 affiliate ban affect consumer shopping on Amazon?
No. The June 2011 termination applied exclusively to the B2B Associates advertising program and never restricted California consumers from purchasing products on Amazon properties.
