Open your DoorDash order and look at the math nobody shows you by default.
A $12 sandwich becomes a $19 charge before the tip. The restaurant, if it’s lucky, sees maybe $9 of that $12 after fees. DoorDash takes a delivery fee from you, a service fee from you, and a commission from the restaurant — sometimes as high as 30% of the order — for the privilege of being discovered by someone who was already hungry and already looking for food nearby.
Nobody voted for this. Nobody sat down and designed a system where a three-party transaction generates a toll for a fourth party that touches none of the food, owns none of the kitchen, and bears none of the risk if the sandwich is bad. It just happened, order by order, platform by platform, until it became the invisible cost of doing business in the modern economy.
This is the platform tax. And unlike an actual tax, nobody voted for it, nobody can vote it out, and the revenue doesn’t fund roads or schools. It funds shareholder returns for companies that have made themselves unavoidable.
What Makes It a Tax
Calling a service fee a “tax” meets the definition better than the discount economy would like to admit. A tax is a mandatory extraction imposed by an entity with power over you, justified by access to something you need, with no meaningful ability to negotiate the rate.
Compare that to what platforms actually do. Amazon charges sellers referral fees, fulfillment fees, storage fees, advertising fees, and “returns processing” fees — a stack that can run 30 to 50% of a product’s sale price depending on category. Etsy takes a listing fee, a transaction fee, a payment processing fee, and, increasingly, an “offsite ads” fee that charges sellers a commission on sales the platform claims credit for whether the seller wanted the ad or not. App stores take 15 to 30% of nearly every digital transaction that flows through a phone, a toll enforced not by market competition but by the simple fact that there are only two app stores that matter and both charge roughly the same rate.
None of these fees are set by a market in any meaningful sense. They’re set by platforms that have already won the market — that have already made themselves the only practical route between a business and its customers — and then priced their toll accordingly. That’s rent extraction (instead of commerce), and it functions exactly like a tax: mandatory, non-negotiable, and collected regardless of whether the underlying transaction was profitable for the parties actually doing the work.
The Aggregate Nobody Calculates
Any single platform fee looks survivable in isolation. Thirty percent hurts, but a restaurant can absorb it, price around it, pass some of it to the customer, and stay open. But it’s a trick: each individual toll is calibrated to be tolerable.
But businesses today don’t pay just one platform tax. They pay several, simultaneously, stacked on top of each other. A small retailer might sell through Amazon (referral and fulfillment fees), advertise through Google and Meta (customer acquisition fees that function as a tax on being found at all), process payments through Stripe or a card network (interchange fees), and run point-of-sale software that takes a cut of in-person transactions, too. Add them up and a business that looks profitable on paper — decent margins, steady sales, positive reviews — can be quietly bleeding 40, 50, even 60% of its gross revenue to a collection of platforms before it pays rent, wages, or itself.
Nobody totals this number for a business owner. There’s no line item on a bank statement that says “cumulative platform extraction.” It’s distributed across a dozen invoices and dashboards, each one designed intentionally to look reasonable on its own. A visible aggregate would provoke outrage!
Where the Money Actually Goes
Defenders of platform fees point to the value being provided: payment processing, logistics, fraud protection, discovery, infrastructure. And it’s true — none of these things are free to build or operate. Pretending platforms provide nothing would be as dishonest as pretending they’re neutral.
But value delivered and value extracted are different numbers, and the gap between them has been widening for years. The infrastructure to process a payment costs a credit card network a tiny fraction of a percent of that payment. The rest they charge is pure margin, protected by a duopoly that has never had to compete on price. Amazon’s logistics network is genuinely impressive, and it is also priced well above the marginal cost of delivering a package, because sellers have no real alternative that reaches the same number of buyers.
The money flows out of local economies and into a small number of platform companies, where it becomes shareholder value, executive compensation, and the capital to acquire whatever competitor might have offered a lower toll. Money that used to circulate within a town — from the customer, to the merchant, to the merchant’s landlord and supplier and employees, all local — now takes a detour through Seattle or Cupertino or Silicon Valley before a fraction of it, if any, makes its way back.
The Toll Booth You Can’t Drive Around
What makes a platform tax different from an ordinary business expense is the absence of an alternative route. If a supplier charges too much, a business can find another supplier. If a platform charges too much, there is often nowhere else to go, because the platform doesn’t controls access to the customers who have consolidated onto that platform in the first place.
This is the part that turns a bad deal into a structural one. Once a critical mass of consumers has decided that Amazon is where they search for products, that DoorDash is how they order food, that Instagram is how they discover small brands, the fee is no longer a price you compare against competitors. It has become a toll on existing at all in the part of the economy where your customers already live. You can refuse to pay it, but refusing means disappearing.
It’s a monopoly rent wearing the costume of a service fee, and it behaves accordingly: it rises over time, it resists negotiation, and it answers to shareholders instead of to the businesses paying it.
What a Tax Without Representation Costs Everyone
The original complaint about taxation without representation wasn’t really about the existence of tolls; it was about the absence of any say in how they were set or where the money went. The platform tax has the same defect, at a larger scale than any single business owner can see from inside their own invoices.
Every dollar that leaves a local business through a platform fee is a dollar that doesn’t pay a local wage, doesn’t get spent at the shop next door, doesn’t get reinvested in the town where it was earned. Multiply that across millions of small businesses and the platform tax is no longer a minor cost of doing business — it becomes one of the largest, least visible transfers of wealth out of local economies in the modern era. And it happens without a single vote.
We didn’t design this system on purpose, in the sense that no legislature wrote it into law. But it was designed — by companies that understood, correctly, that a toll distributed across millions of small, invisible transactions draws far less resistance than one large, visible one ever could.
