UK Digital Services Tax 2026: What Online Businesses Need to Know
The UK Digital Services Tax explained -- the 2% charge on revenues of large digital platforms, who it applies to, revenue thresholds, calculation method, and the outlook for DST's future.
What is the UK Digital Services Tax?
The Digital Services Tax (DST) is a UK levy charged at 2% on the revenues of large technology companies that provide certain digital services to UK users. It was introduced on 1 April 2020 and is intended as a temporary measure pending global agreement on how to tax the digital economy.
DST is a revenue tax, not a profit tax. It is charged on the gross revenues a business generates from providing in-scope digital services to UK users, regardless of whether the business is profitable. This is a deliberate design choice -- many large digital platforms have historically paid little Corporation Tax in the UK due to the use of loss carry-forwards, transfer pricing, and thin profit margins on UK operations.
Which businesses are in scope?
DST applies to businesses that provide the following types of digital services to UK users:
Social media platforms
Platforms that allow users to interact, share content, and communicate with each other. This includes Facebook, Instagram, TikTok, LinkedIn, Twitter/X, and Snapchat -- in the broad sense of platforms whose value derives from connecting users with each other.
Search engines
Online search services that allow users to search across internet content. This primarily covers Google Search and Bing, but also vertical search engines and price comparison sites where the primary activity is aggregating and presenting search results.
Online marketplaces
Platforms that facilitate transactions between buyers and sellers, where the platform derives revenue from facilitating those transactions. This covers Amazon Marketplace, eBay, Etsy, Airbnb, and Uber (in its role as an intermediary). Pure direct-to-consumer retailers (e.g. an online shop selling only its own goods) are not in scope.
What is not in scope
- Financial and payment services (they are regulated differently).
- Online content streaming (Netflix, Spotify) where the platform does not connect users with third-party sellers.
- Direct retail (ASOS.com selling only ASOS products).
- Software as a Service (SaaS) products.
- Advertising networks that are not themselves social media or search platforms.
Revenue thresholds
DST only applies if both of the following conditions are met for the group as a whole:
- Global revenues from in-scope digital activities exceed £500 million per year.
- UK revenues from in-scope digital activities exceed £25 million per year.
These thresholds are assessed on a group basis, not entity by entity. If a parent company and all its subsidiaries together cross both thresholds, all UK revenues from in-scope activities are within DST scope.
The £25 million allowance
Even if a group exceeds both thresholds, the first £25 million of UK in-scope revenues per year is exempt from DST. Only revenues above £25 million are subject to the 2% charge.
How UK revenues are calculated
"UK revenues" for DST purposes are revenues that are attributable to UK users. The rules for attribution differ by service type:
- Social media / search engines: revenues from advertising displayed to UK users are UK revenues, even if the advertising contract is with an overseas advertiser.
- Online marketplaces: revenues from transactions where the buyer or seller (or both) are UK users are UK revenues. If only one party is UK-based, a 50:50 split is typically used.
- Ride-hailing and similar: revenues from journeys starting in the UK are UK revenues.
Where it is not possible to directly attribute revenues to UK users, HMRC accepts reasonable estimates based on user data.
Worked example: DST calculation for a large marketplace
Facts:
- Online marketplace with global in-scope revenues of £2.5 billion (above the £500m threshold).
- UK revenues from marketplace facilitation fees: £180 million.
- UK revenues from marketplace advertising: £45 million.
- Total UK in-scope revenues: £225 million (above £25m threshold -- DST applies).
DST calculation:
- Total UK in-scope revenues: £225,000,000
- Less: £25m allowance: (£25,000,000)
- Taxable UK revenues: £200,000,000
- DST at 2%: £4,000,000
The group pays £4 million DST for the year, in addition to any Corporation Tax on UK profits.
Corporation Tax deduction: If the group pays 25% Corporation Tax on UK profits, the £4 million DST payment is an allowable expense, reducing the Corporation Tax bill by £4m x 25% = £1 million. The net cost of the DST after CT relief is £3 million.
Safe harbour provisions
The legislation includes a safe harbour mechanism for groups in a loss-making position or with very low profit margins:
- If the group's global operating margin is below 10%, DST liability can be capped using a reduced rate or alternative calculation.
- This prevents DST from creating an existential cash burden on loss-making but high-revenue platforms.
The safe harbour is complex to apply and requires detailed supporting calculations.
DST vs Corporation Tax: the key differences
| Feature | DST | Corporation Tax |
|---|---|---|
| Base | Revenue (turnover) | Profits |
| Rate | 2% | 25% (main rate) |
| Loss offsets | Cannot offset losses | Losses can be carried forward |
| Territorial scope | UK users only | UK-source profits |
| Threshold | £500m global / £25m UK | Applies from first pound of profit |
| Filing | Annual DST return | CT600 |
| CT deduction | DST is deductible | n/a |
US-UK trade tension over DST
The United States has been a vocal critic of digital services taxes imposed by European and UK governments, arguing that they disproportionately target US technology companies (Google, Meta, Amazon, Apple, Microsoft). The US Trade Representative (USTR) has in the past threatened retaliatory tariffs on imports from DST-applying countries.
Under the Biden administration, a temporary truce was agreed in 2021 pending OECD Pillar One negotiations. Under subsequent US administrations, the US has periodically reignited DST as a trade grievance.
The UK government has consistently said it will repeal DST when a "satisfactory multilateral solution" is in place -- specifically, when OECD Pillar One is implemented. Pillar One would reallocate taxing rights on a portion of large digital companies' profits to the countries where users are located, effectively replacing unilateral DSTs with a coordinated global approach.
OECD Pillar One and the future of DST
Pillar One of the OECD/G20 Inclusive Framework would allocate 25% of the residual profits of the largest multinationals (global revenues over EUR 20 billion) to market jurisdictions (where users are). This would give the UK a share of profits from large digital platforms based on UK user revenues.
In exchange, participating countries would eliminate their unilateral DSTs. The UK has signalled it would comply with this bargain.
As of mid-2026, Pillar One has not entered into force globally. The main obstacle is ratification in the United States. Until Pillar One is live, UK DST continues.
Who pays and what does it cost the large platforms?
HMRC publishes aggregate DST statistics but does not publish company-by-company figures. Market estimates suggest the largest payers include:
- Meta (Facebook/Instagram/WhatsApp): substantial UK advertising revenues.
- Alphabet (Google/YouTube): search advertising and YouTube advertising.
- Amazon: marketplace facilitation fees and advertising.
- Microsoft (Bing/LinkedIn): relatively smaller UK in-scope revenues.
- Airbnb, Uber, eBay: marketplace revenues.
The total UK DST receipts have been approximately £350-400 million per year since introduction, a relatively modest sum compared to VAT or Corporation Tax from the same companies.

Frequently asked questions
What is the UK Digital Services Tax rate and who does it apply to?
The UK Digital Services Tax is charged at 2% on UK revenues from social media platforms, search engines, and online marketplaces. It only applies to groups with global revenues exceeding £500 million per year AND UK revenues from in-scope activities exceeding £25 million per year. Revenues below the £25 million UK threshold are not charged.
Is DST the same as Corporation Tax?
No. DST is a separate tax, not a profit-based tax. It is charged on revenues (turnover), not profits. A company can pay DST even if it makes a loss. DST is reported and paid separately from Corporation Tax, although DST paid is an allowable deduction for Corporation Tax purposes.
Will the UK DST be abolished?
The UK government has indicated it will repeal DST when a satisfactory multilateral solution is agreed internationally, particularly through the OECD Pillar One framework. Negotiations have been ongoing since 2019. As of 2026, no global agreement has been fully implemented, and UK DST remains in force. The US has threatened retaliatory tariffs on DST-applying countries, creating diplomatic tension.
