What it means
The problem these taxes attack is simple to state. A group can sell heavily into one country while booking the profit in another, usually by placing intellectual property, brand rights or a contracting entity in a low-tax jurisdiction and charging the local operating company large fees for using them.
The result is high local sales and very little local taxable profit. Governments responded in two ways.
A diverted profits tax applies a penal rate to profit that a tax authority judges has been artificially moved offshore, and the rate is deliberately set above the normal corporation tax rate to encourage companies to restructure rather than pay it. A digital services tax takes a blunter route and charges a percentage of revenue earned from local users, typically for search advertising, social media advertising and online marketplaces.
For finance teams the practical impact is felt in three places: the effective tax rate, the cash tax forecast and the transfer pricing documentation that supports intra-group charges. A digital services tax is charged on revenue rather than profit, so it lands even in a loss-making year and often cannot be credited against corporation tax in the home country.
That makes it feel more like an operating cost than a tax, and many companies record it above the tax line in their accounts. Scope rules keep these taxes away from smaller businesses.
Digital services taxes generally apply only above a global revenue threshold and a local revenue threshold, so a company must be large worldwide and meaningfully present locally before anything is due. Diverted profits rules apply more widely but usually require a tax authority to show a real lack of economic substance behind the arrangement.
The picture is unsettled and moving. International agreement on reallocating some taxing rights to market countries, together with a global minimum corporation tax rate, was intended to make unilateral digital services taxes unnecessary, and several countries have committed to withdraw theirs once those rules are fully in force.
Until that happens, groups selling digitally across borders should assume they may face overlapping charges in several countries at once.
In practice
Real-world examples.
Example
A streaming platform passes both the global and local revenue thresholds in a European market. Its finance team adds a 2% charge on local subscription and advertising revenue to the budget, and the commercial team raises local list prices to recover part of it.
Example
A consumer goods group licenses its brand from a holding company in a low-tax jurisdiction and pays a 6% royalty on local sales. The tax authority opens a diverted profits enquiry, arguing the holding company has two staff and no real decision-making, and the group renegotiates the royalty to a defensible level.
Example
An online marketplace operating in four countries finds that three of them charge a digital services tax on the same commission revenue in overlapping ways. The group builds a country-by-country revenue model so it can forecast the cash cost and disclose the exposure to its audit committee.
Formula
Calculation
Digital Services Tax = (In-scope local digital revenue - Local allowance) x DST rate
Consider Palewood Media, a large advertising technology group. In one country it earns $80,000,000 of in-scope digital revenue attributable to local users. That country charges a 3% digital services tax and allows the first $30,000,000 of local revenue to be exempt.
Taxable base = $80,000,000 - $30,000,000 = $50,000,000
Digital services tax = $50,000,000 x 3% = $1,500,000
The sting is clearer once you compare it with profit. If Palewood's local operating margin is 10%, its local profit on that $80,000,000 is $8,000,000, so the $1,500,000 charge equals 18.75% of local profit before any corporation tax is calculated. A weak year makes it worse: at a 5% margin, local profit is $4,000,000 and the same $1,500,000 charge takes 37.5% of it.Case study
Seen in the real world.
Corvane Search Group is a fictional company created purely to illustrate how these rules bite. Corvane earned $240,000,000 of advertising revenue from users in one country but reported local taxable profit of only $6,000,000, because its local subsidiary was paid a small service fee while the advertising contracts sat with an offshore affiliate holding the technology rights.
The tax authority applied a digital services tax of 2% to $200,000,000 of in-scope revenue after allowances, producing a $4,000,000 charge, and separately opened a diverted profits enquiry into the offshore contracting structure. Corvane's board concluded that fighting on two fronts was more expensive than restructuring, so it moved contracting and a genuine sales team into the local subsidiary.
In the illustrative outcome, local taxable profit rose to $34,000,000 and normal corporation tax replaced the penal charge. The total tax bill was higher than the old structure produced but lower than the combined digital services tax and diverted profits exposure, and the disclosure risk disappeared.
Watch out
Common mistakes.
- Assuming the tax only applies to technology companies. Diverted profits rules apply to any large group with cross-border related-party charges, including consumer goods, pharmaceuticals and industrial businesses.
- Budgeting a digital services tax as part of the corporation tax line. It is charged on revenue, arises even in loss years, and is usually treated as an operating cost rather than an income tax.
- Believing intra-group pricing is safe because a lawyer signed the contract. Tax authorities look at where people actually make decisions and take risk, not at the wording of the agreement.
Questions
People also ask.
Is google tax an official name for anything?
No, it is journalistic shorthand; the formal names are diverted profits tax, digital services tax and similar country-specific labels.
Can a digital services tax be credited against tax at home?
Usually not, because it is not an income tax, so it tends to be a genuine extra cost rather than a timing difference.
Do small businesses need to worry?
Almost never, since these taxes carry global and local revenue thresholds that keep them aimed at very large groups.
