$100k MRR SaaS. Same business, 7 countries. What the founder actually keeps per year: Cayman: $720k Dubai: $664k Hong Kong: $622k Cyprus: $607k Estonia: $562k US: $479k UK: $346k Dubai vs London: $318k a year. Everyone's hyping Cyprus right now. Read the fine print first. The setup: $1.2M revenue, 60% margin = $720k profit. Founder lives in the same country. All profit paid out as dividends. 2026 rules. US is federal only, state tax comes on top. Cyprus is not 12.5% anymore. 15% corporate tax since Jan 1, 2026. Non-dom = 0% defence tax on dividends, but you still pay a 2.65% health contribution (capped at €4,770/yr). ~15.8% all-in. Still good. Just not what you were sold. Dubai is not 0%. 9% corporate tax above AED 375k since 2023. The free zone 0% only applies to "qualifying income," and SaaS isn't on the list. So most SaaS founders pay 9%. ~7.7% all-in, 0% personal tax. I live here. Still the best number you can actually live with. Cayman is 0%. Also: no Stripe, substance rules, and if you don't live there, your home country taxes it anyway. It's a fund address, not a SaaS HQ. UK: 25% corp tax + dividend tax up to 39.35% (went up again April 2026). ~52% total. Cheapest country to start a company (£100). Most expensive country to succeed in. US LLC for non-residents is not a tax hack. Usually no US federal tax, but your home country taxes the profit. Forget one Form 5472 = $25,000 penalty. The LLC gets you Stripe and a US bank. Not a lower tax bill. Setup cost, roughly: UK: ~$130 Stripe Atlas (Delaware): $500 Hong Kong: ~$500 gov fees + agent Cyprus: $2-4k Dubai free zone w/ visa: $5-6k Cayman: $3-6k Cyprus, HK and UAE free zones also need an audit every year. Budget $2-9k. Where you incorporate matters way less than where YOU live. Company in Cyprus + you in Berlin = German tax. Company in Dubai + you in London = UK tax. Move first. Incorporate second. If you go the Delaware route from abroad, the stack is: EIN Registered agent US address US bank US phone number The phone number is the one everyone forgets until a US client asks for it. I built @BubblyPhone partly for this: US number, $3/mo, works in your browser. Use it for clients and vendors, not bank OTPs. Most banks reject VoIP. Not tax advice. Illustrative numbers, 2026 rules. Get an adviser in both countries before you move anything.
