What Significant Economic Presence tax is trying to capture
For years, foreign digital businesses could earn heavily from Kenyan users without a local office, a warehouse, or any physical footprint the tax system could grab onto. Significant Economic Presence tax, usually shortened to SEP tax, is Kenya's answer to that. It says that if a non-resident derives income from a digital marketplace or platform that serves people in Kenya, the country has a right to tax a slice of it, even though the business never sets foot here. This calculator turns your Kenya-derived digital turnover into the tax that approach produces.
It is aimed at non-resident operators of apps, streaming services, online marketplaces, advertising platforms, and similar digital businesses with Kenyan customers, and at the finance and tax teams who have to budget for the charge. Resident businesses and ordinary employees do not pay SEP tax, so if you are based in Kenya this tool is mostly useful for understanding what your foreign suppliers face.
A deemed margin, not a tax on your real profit
The mechanics matter and are easy to misread. SEP tax does not look at your actual profit margin. Instead the law deems your taxable profit to be a fixed percentage of your Kenya-derived gross turnover, then taxes that deemed profit at the corporate rate. The deemed margin this calculator applies is 10 percent, and the rate applied to it is 30 percent. Multiply those together and you get an effective charge of 3 percent of gross turnover. The trap people fall into is thinking it is 30 percent of turnover or 10 percent of profit. It is neither. It is 10 percent times 30 percent, landing at 3 percent of the top line. Because it is anchored to turnover rather than genuine profit, a low-margin platform can feel the charge more sharply than a fat-margin one. These figures sit in recently changed legislation, so confirm the current margin and rate with the Kenya Revenue Authority before relying on them.
Ten million shillings of Kenyan turnover, step by step
Suppose a non-resident platform books KES 10 million of Kenya-derived digital turnover in a period. The calculation runs in two short moves, and the table below mirrors exactly what the tool returns.
| Step | Amount (KES) |

The live chart in the results panel above makes the proportion obvious. The whole bar is turnover; the small teal block is the SEP tax. Everything else is untouched.
How SEP fits with the taxes it replaced
SEP tax did not appear in a vacuum. It took over from the old Digital Service Tax, which was charged at a flat 1.5 percent of gross turnover. The separate 3 percent Digital Asset Tax that briefly applied to crypto and similar transfers has also been repealed in the changes this calculator reflects. So a non-resident who once juggled DST should now be thinking in SEP terms instead. There can also be a withholding tax angle on payments routed through a digital marketplace, which is a different mechanism handled by the paying party, so do not confuse the two. Because this area has churned through successive Finance Acts, the safest move is to check the live position with the KRA rather than assume last year's rules still hold.
How do I know which turnover counts as Kenya-derived?
Broadly, it is the income attributable to users or customers located in Kenya, identified through signals such as the user's location, payment details, or device. Apportioning global revenue down to a Kenyan figure is the genuinely hard part of compliance, and getting it wrong in either direction creates risk. Keep clear records of how you split it and document your method, because the KRA can ask you to justify the Kenya-derived figure.
Does charging VAT on digital services replace SEP tax?
No, they are separate obligations. VAT on digital services is an indirect tax collected from the customer and remitted, while SEP tax is a direct tax on the platform's deemed income. A non-resident digital supplier can be on the hook for both at once. Treat the 3 percent effective SEP charge and any VAT registration as distinct items in your budget, and confirm both registration triggers with the KRA.
