A DST tax, or digital services tax, is a country-level levy on the gross revenue that large technology companies earn from online advertising, digital marketplaces, and user data tied to users located in that country. Rates typically fall between 1.5% and 7.5%. Unlike corporate income tax, a DST does not care whether the company is profitable or even has an office in the taxing country. It exists because the older international rule that taxed a company only where it had a physical presence broke down once platforms could earn billions from a country’s users without ever setting foot there.
What Kinds of Revenue Are Taxed
Most countries that have adopted a DST reach three categories of digital revenue. The first is targeted online advertising, where a platform sells placements aimed at users based on browsing behavior, search history, or location. The second is digital intermediation: a platform that connects buyers and sellers, or matches users with each other, for a fee. Ride-hailing apps, food-delivery services, and online marketplaces sit here. The third is revenue from collecting and selling user data tied to either of the first two.1Office of the United States Trade Representative. Report on France’s Digital Services Tax
These categories can overlap. A social media company that runs targeted ads and also operates an e-commerce marketplace can owe DST on revenue from both. The common thread is that each activity relies on automated systems and user engagement to generate value, and the taxing government’s argument is that the value should be taxed where the user sits, not where the company is headquartered.2Congressional Research Service.

Which Companies Actually Owe It
A DST is designed to reach large multinationals, not small businesses or local startups. Nearly every country uses a two-tier threshold. The first tier is a global revenue floor, which most jurisdictions set at €750 million in total annual revenue from all sources. A company below that number owes nothing.1Office of the United States Trade Representative. Report on France’s Digital Services Tax
The second tier is a local revenue threshold measuring how much the company earns from covered digital services inside that specific country. This is where the variation shows up. France sets its local threshold at €25 million in domestic digital revenue.1Office of the United States Trade Representative. Report on France’s Digital Services Tax The United Kingdom uses £25 million in UK user revenue.3GOV.UK. Digital Services Tax Spain’s local floor is only €3 million.4Office of the United States Trade Representative. Report on Spain’s Digital Services Tax Italy recently eliminated its local threshold entirely, so any digital revenue earned there by a qualifying multinational is taxable. A company must clear both the global and local thresholds before the tax applies.
Why It Taxes Revenue, Not Profit
The single biggest difference between DST and corporate income tax is what gets taxed. Corporate income tax applies to net profit: total revenue minus operating costs, salaries, depreciation, and other deductions. A company that earns $10 billion and spends $9.5 billion reports $500 million in taxable income. DST skips the expense calculation and taxes gross revenue, so the full qualifying amount is the starting number.
The design is deliberate. Large digital companies have long used transfer pricing and intellectual property licensing to shift profits into low-tax jurisdictions, leaving little taxable income where their users actually live. A gross revenue tax sidesteps that strategy because revenue cannot be reclassified the way profit can. The trade-off is that a company can owe DST in a year when it is losing money in the local market, which critics say penalizes fast-growing platforms investing in new countries.
Rates by Country
More than two dozen countries now collect some form of digital services tax, and the rates vary considerably. Among the major economies:
- United Kingdom: 2% on revenue from search engines, social media platforms, and online marketplaces, with a £25 million allowance so a group’s first £25 million in UK user revenue is untaxed.3GOV.UK. Digital Services Tax
- France: 3% on revenue from targeted advertising and digital intermediation services.1Office of the United States Trade Representative. Report on France’s Digital Services Tax
- Spain: 3% on advertising revenue, online intermediation, and data transmission services.4Office of the United States Trade Representative. Report on Spain’s Digital Services Tax
- Italy: 3% on advertising, digital interfaces, and user data sales.
- Canada: 3% on revenue from online marketplaces, online advertising, social media platforms, and data licensing, applied retroactively to January 2022.5Congressional Research Service. Canada’s Digital Services Tax Act: Issues Facing Congress
- Turkey: 5% as of January 2026, reduced from a previous rate of 7.5%.
- Austria: 5% on online advertising revenue.
- Hungary: 7.5%, one of the highest rates in the world.
Outside Europe and North America, countries across Africa, South America, and Asia have adopted their own versions, with rates as low as 1.5% in Kenya and Poland and as high as 12% in Uruguay. The lack of a global standard means a single multinational can face DST obligations in a dozen jurisdictions, each with different rates, thresholds, and definitions of which services qualify.
How a User’s Country Gets Determined
Because DST is owed based on where the user is located, figuring out a user’s country matters. Tax authorities generally do not prescribe a single method. They expect companies to use the best available evidence from their own data. The UK’s guidance spells this out practically: companies should consider delivery addresses, payment details, IP addresses, the intended destination of advertising set by contract, and even the location of rented property listed on a marketplace.6HMRC. DST33000 – Evidence Identifying a UK User
When data points conflict, the company must judge where the user is “normally” located, not just where they happened to be during a single transaction. A tourist browsing from a London hotel with a billing address in Tokyo is likely a Japanese user for DST purposes. The compliance burden sits with the platform, which already collects most of this information for its own targeting.
Double Taxation and the U.S. Credit Problem
DST payments generally cannot be credited against U.S. corporate income tax the way a foreign income tax can. Under U.S. tax law, only taxes based on net income qualify for the foreign tax credit. Because DSTs are levied on gross revenue with no deductions allowed, the IRS treats them as a different category.7Internal Revenue Service. Foreign Tax Credit
The Treasury Department reinforced this position in 2022 by finalizing regulations that tightened the definition of a creditable foreign tax, adding an attribution requirement that asks whether the foreign tax connects revenue to the taxpayer’s own activities in a way that parallels U.S. income tax principles. DSTs attribute revenue based on where the service recipient is located rather than where the company operates, and they do not meet that standard. The practical result: a U.S. company paying a 3% French DST and a 21% U.S. corporate income tax on overlapping revenue receives no credit and no deduction for the DST payment under current rules.
Where the OECD Pillar One Deal Fits
The intended long-term fix for this patchwork is a multilateral agreement led by the OECD known as Pillar One. Over 135 jurisdictions have endorsed the framework, which would replace individual country-level DSTs with a coordinated system for reallocating taxing rights.8OECD. Multilateral Convention to Implement Amount A of Pillar One The core mechanism targets the largest and most profitable multinationals and reallocates a share of their excess profit to the countries where their revenue is earned. In exchange, participating countries would repeal their unilateral DSTs.9OECD. Pillar One Amount A Fact Sheet
The agreement has stalled. A June 2024 deadline to finalize the Multilateral Convention came and went without a signed treaty. Countries already collecting DST revenue have little incentive to give it up for a theoretical future system. In the meantime, new DSTs keep appearing. Canada enacted its 3% DST in mid-2024 with retroactive effect to 2022.5Congressional Research Service.

Do These Taxes Reach Consumers and Advertisers
Whether the cost gets passed along depends on the company and the market. When France and the UK enacted their DSTs, Amazon and Google publicly announced they would pass the cost on to advertisers and marketplace sellers. Facebook and eBay chose to absorb it. Those different responses reflect a real economic question: a company already charging the profit-maximizing price for ads theoretically cannot raise prices further without losing customers, but a dominant platform with limited competition may have more room than textbook models predict.
For a small business buying online advertising, a 2% to 3% increase in ad costs adds up over a year. Marketplace sellers on platforms that pass the tax through may see higher commission fees or listing costs. Individual consumers are the least likely to see a line item labeled “DST” on a receipt, but the tax can work its way into retail prices indirectly through the advertising costs that businesses fold into what they charge.
