A broad corporate income tax generally taxes a company’s profit across a much wider range of business activities. The phrase “broad corporate levy” is descriptive here, not the name of one standardized tax. A DST is usually designed to apply alongside ordinary corporate income tax, not replace it.
How a DST differs from a broad corporate income tax
| Comparison | Typical digital services tax | Typical corporate income tax |
|---|---|---|
| Tax base | Gross revenue from specified digital services or transactions. | Net profit or income after allowable costs, as defined by local law. |
| Activities covered | Selected digital activities, often linked to users or customers in the taxing market; exact categories and thresholds vary by jurisdiction. | A much wider range of a corporation’s business income, subject to local rules. |
| Relationship between the taxes | Generally intended to operate in addition to a generally applicable income tax, rather than as a substitute. OECD commentary on the GloBE rules says DSTs are generally not covered taxes under those rules because they are usually gross-revenue taxes operating alongside ordinary income taxes. | Local systems determine how corporate income tax interacts with other taxes, including any available credits. |
The different tax bases matter. A business can have covered revenue but little or no profit after costs. Because a gross-revenue tax does not deduct all costs used to earn that revenue, a DST may apply even when the relevant activity has a low margin or a loss. That is a structural feature of the tax base, not a prediction about every company’s liability.
What services a DST can cover
There is no single worldwide definition of a DST. Laws differ in which services they cover, how they connect revenue to local users, and which thresholds or exclusions apply. The OECD’s Pillar One blueprint proposed an illustrative scope for automated digital services that included online advertising, sale of user data, search engines, social media, online intermediation, digital content, online gaming, standardized online teaching, and cloud computing.
That blueprint also proposed exclusions, including customized professional services, customized online teaching, physical goods, internet-access services, and ordinary online sales outside its defined automated digital services categories. These lists describe a policy proposal; they are not a binding checklist for national DST statutes.

A DST is also not simply a VAT or sales tax on all digital purchases. The IMF’s 2026 paper describes DSTs as sector-specific turnover taxes and distinguishes them from both profit-based income taxes and traditional consumption taxes. It notes that definitions of taxable services vary.
Examples: the UK design and Canada’s reported repeal
| Jurisdiction and source date | What the official source says | How to read the example |
|---|---|---|
| United Kingdom, 2020 announcement | The government announced a 2% tax, starting April 1, 2020, on revenues of search engines, social media services, and online marketplaces deriving value from UK users. UK policy announcement | This is the original design described in that announcement, not a complete account of thresholds, reliefs, or later amendments. The government’s 2025 review calls the DST a narrow-scope business tax that taxes revenues from specific digital services, and describes it as an interim measure while a global solution is pursued. |
| Canada, 2026 status page | The government describes the DST as a 3% tax on certain revenues earned by large domestic and foreign businesses engaging online users in Canada. It reports that repeal legislation received Royal Assent on March 26, 2026. Government of Canada DST page | The repeal date is a legal-status update, not a change to the stated rate. Check current official materials for the law’s application to a particular period or liability. |
How the OECD’s international proposal fits in
OECD Pillar One Amount A is a separate profit-reallocation framework, not another name for a DST. The OECD describes the Amount A multilateral convention as reallocating a share of profits from the largest and most profitable multinational enterprises to market jurisdictions, improving tax certainty, and removing DSTs under the convention.
That description sets out the framework’s intended architecture; it does not establish that a uniform replacement tax is in force worldwide or that every country has repealed its domestic DST. The UK’s description of its DST as an interim measure and Canada’s reported 2026 repeal illustrate why status must be checked country by country and date by date.
Quick Recap
What to keep in mind
- A DST is generally a tax on gross revenue from selected digital services; corporate income tax generally applies to profit across broader business activity.
- The name “digital services tax” does not guarantee that two countries tax the same services or use the same thresholds.
- For a specific company, country, or tax period, the applicable statute and current official guidance—not the general label—determine the treatment.
