At a common $150,000 gross salary point
Here's the ranking before the mechanics: at a $150,000-equivalent gross salary, the UAE and Saudi Arabia tie for first at a genuine 0% effective tax rate, no income tax, no payroll deduction, full gross paid as net. Singapore comes third for a foreign Employment Pass holder at roughly 10.3%, Hong Kong fourth at roughly 14.8%, and Zurich, Switzerland last on this list at a real, progressive effective rate near 26.6%.
That last figure is the point of this article. "Tax-free" and "low-tax" get used interchangeably in every generic "best countries for expats" listicle, but they're not the same category. Two of these five markets are genuinely 0%. Two more are low but real, single-digit-to-mid-teens progressive tax with one big carve-out for foreigners. Switzerland isn't tax-free at all, it's a real, stacked, three-layer tax bill that just happens to be moderate by European standards. If you're weighing offers across any of these five, knowing which bucket each one falls into matters more than the country's general reputation.

Open the UAE calculatorHow each of these five markets actually taxes a tech salary
UAE and Saudi Arabia run the simplest system there is: no personal income tax at all, for anyone, and no payroll deduction for expatriate employees specifically. The UAE's GPSSA pension scheme and Saudi Arabia's GOSI social insurance both exist, but both apply to nationals only, not to the expat workforce that fills most tech roles in Dubai, Abu Dhabi, Riyadh, and Jeddah. Gross salary is net salary, full stop, every month.
Singapore runs a genuine progressive Income Tax scale, IRAS bands from 0% up to 24% on chargeable income over S$1,000,000. What keeps Singapore near the top of this ranking is CPF, the mandatory savings scheme, being scoped to Citizens and Permanent Residents only: an Employment Pass or S Pass holder pays income tax and nothing else.
Hong Kong calculates Salaries Tax two different ways and automatically charges whichever is lower: progressive bands (2% to 17%, in HK$50,000-wide steps, after a basic personal allowance) or a flat-ish standard rate (15% on the first HK$5 million of net income, 16% above that). On top of whichever tax figure wins, MPF (5% of relevant income, capped at HK$18,000/year) applies to most foreign employees too, not just local hires.
Switzerland (Zurich) is the genuine outlier on this list. There's no flat national income tax anywhere in Switzerland: federal tax, Canton of Zurich cantonal tax, and City of Zurich communal tax all stack on the same taxable income, and then AHV/IV/EO (5.3%), ALV (1.1% up to a ceiling), and age-banded BVG pension contributions come out on top. It's genuinely progressive, genuinely real money, and the only one of these five that isn't a special low-tax carve-out for foreign employees specifically.
Ranked: take-home on a $150,000-equivalent gross salary
Same US-dollar gross salary, converted into each local currency at a stated FX rate (AED and SAR are hard-pegged to the dollar; HKD trades in a narrow band; SGD and CHF float and use an approximate July 2026 spot rate), run through the same engines behind each market's calculator.
| # | Market | Headline mechanic | Eff. rate | Net/yr |
|---|---|---|---|---|
| 1 | UAE (Dubai / Abu Dhabi) | 0% income tax, 0% payroll deduction for expats | 0.0% | AED 550,875 |
| 2 | Saudi Arabia (Riyadh / Jeddah) | 0% income tax, 0% payroll deduction for expats | 0.0% | SAR 562,500 |
| 3 | Singapore | Progressive Income Tax, 0% to 24% | 10.3% | S$ 173,520 |
| 4 | Hong Kong | Lower of progressive Salaries Tax or a 15%/16% standard rate | 14.8% | HK$ 996,600 |
| 5 | Switzerland (Zurich) | Federal + cantonal + communal tax, genuinely progressive | 26.6% | CHF 89,151 |
UAE and Saudi Arabia figures assume expatriate status (the common case for tech hires in both markets). Singapore assumes Employment Pass status (0% CPF). Hong Kong assumes a foreign employee past the 13-month MPF exemption window. Switzerland assumes a single filer, age 30, City of Zurich, no church tax. None of these figures include cost of living, which varies sharply across all five cities and is a separate question from tax.
What actually makes each market's system distinct
UAE (Dubai / Abu Dhabi)
GPSSA pension applies to UAE nationals only, not expats. The only cost that matters is gratuity math at exit, not anything monthly.
Saudi Arabia (Riyadh / Jeddah)
GOSI's 9.75% employee rate applies to Saudi nationals only. Expats cost their employer a 2% occupational-hazards levy that never touches take-home pay.
Singapore
CPF, Singapore's mandatory savings scheme, is Citizen/PR only. An Employment Pass or S Pass holder pays income tax and nothing else.
Hong Kong
IRD runs both calculations and charges whichever is lower automatically. MPF (5%, capped at HK$18,000/yr) applies to most foreign employees too.
Switzerland (Zurich)
Not tax-free at all. Three tax layers plus AHV/ALV/BVG social insurance stack up to a real bill, the only market on this list where that's true.
"Tax-free" and "low-tax" are not the same category
Generic "best tax-free countries" lists routinely lump the UAE, Saudi Arabia, Singapore, Hong Kong, and Switzerland into one bucket because they all sound low-tax next to the UK, Ireland, or most of Western Europe. They are not equivalent. The UAE and Saudi Arabia are genuinely 0%, zero income tax and zero payroll deduction for expat employees. Singapore and Hong Kong are meaningfully low, mid-single-digits to mid-teens effective rate at this salary level, with a specific foreigner carve-out (CPF exemption, or the MPF 13-month window) doing most of the work. Switzerland, and Zurich specifically, is a real progressive tax jurisdiction that happens to sit below France, Germany, or the UK on international comparisons, not a tax haven. Treat "low-tax" claims about Switzerland with the same scrutiny you'd apply to any other European country's tax system, because that's genuinely what it is.
Switzerland (Zurich) in detail: the market that breaks the "tax-free Gulf hub" pattern
Zurich is the newest addition to this list and the one that most needs its own explanation, because it doesn't behave like the other four. There is no flat Swiss national income tax: the same taxable income gets hit three separate times. Federal tax (Direkte Bundessteuer) runs a genuinely progressive scale up to 11.5% at the top. Canton of Zurich cantonal tax starts from a "simple tax" base schedule (0% up to roughly CHF 13% at the top bracket) and then multiplies that base by the canton's own Staatssteuerfuss, 95% for 2026-2027. City of Zurich communal tax uses the same simple-tax base again, multiplied by the city's own Gemeindesteuerfuss, 119% for 2026, which is actually the largest single layer of the three once you convert the multiplier into effective rate terms.
On top of all three tax layers, an employee also pays AHV/IV/EO (Switzerland's first-pillar state pension, unemployment and disability insurance, 5.3% employee share, uncapped), ALV (unemployment insurance, 1.1% up to a CHF 148,200 earnings ceiling), and BVG (the mandatory second-pillar occupational pension, age-banded, roughly 3.5% employee share at age 30 on coordinated salary). None of that exists in the UAE, Saudi Arabia's expat track, or Singapore's Employment Pass track. At a CHF-equivalent of our $150,000 test salary, the combined bite lands at roughly 26.6%, more than double Hong Kong's figure and comfortably in the same territory as many EU countries.
The upside case for Zurich isn't the tax rate, it's everything else: currency stability, a strong tech and finance job market, genuinely high salaries in CHF terms, and a lifestyle and infrastructure package the four lower-tax markets on this list don't try to compete on. Choose Zurich for those reasons, not because someone told you Switzerland is a tax haven, because on the payroll numbers alone, it plainly isn't one.

Frequently asked questions
Which of these five countries has the highest take-home pay for a tech salary in 2026?
The UAE and Saudi Arabia tie for first, both genuinely 0% personal income tax and 0% payroll deduction for expatriate employees, so gross equals net in either place. On a $150,000-equivalent gross salary, that's AED 550,875 in Dubai or SAR 562,500 in Riyadh, with nothing coming out of the payslip. Singapore comes third on an Employment Pass (effective rate around 10.3%), Hong Kong fourth (around 14.8%), and Zurich, Switzerland last on this list at a real progressive-tax bite of roughly 26.6%.
Is Switzerland (Zurich) really "tax-free" like the UAE or Saudi Arabia?
No, and this is the single most common misconception about Switzerland's reputation as a low-tax country. Zurich stacks three separate tax layers, federal income tax, Canton of Zurich cantonal tax, and City of Zurich communal tax, on top of AHV/IV/EO, ALV, and BVG pension contributions. At a CHF-equivalent of our $150,000 test salary, that's a real effective deduction rate near 26.6%, nowhere close to the UAE or Saudi Arabia's genuine 0%. Switzerland's low-tax reputation is about certain other cantons (Zug, Schwyz) and about being low relative to high-tax EU neighbours, not about being anywhere near tax-free.
Singapore or Hong Kong: which taxes tech salaries less for a foreigner?
Singapore, for most foreign tech hires, mainly because CPF (Singapore's mandatory savings scheme) doesn't apply to Employment Pass or S Pass holders at all, while Hong Kong's MPF does apply to most foreign employees once a work visa runs past 13 months. That structural gap usually outweighs the headline tax-rate difference. For the full worked comparison across three salary points, GOSI-style deduction tables, and the MPF 13-month exemption nuance, see our dedicated Singapore vs Hong Kong deep dive rather than this hub's summary numbers.
Are the UAE and Saudi Arabia genuinely identical for expat take-home pay?
On monthly take-home, yes, both are a flat 0% with zero deductions for expats. Where they actually differ is what happens when you leave the job: the UAE's gratuity is capped at two years' basic salary, while Saudi Arabia's end-of-service benefit under Article 84 has no cap at all and overtakes the UAE figure once you pass roughly five years of tenure. If you're choosing between a Riyadh and a Dubai offer specifically, that exit-payout math, not the tax rate, is the number worth running, and it's covered in full in our Saudi Arabia vs UAE comparison.
Does this ranking account for cost of living?
No, deliberately not. This is a take-home mechanics ranking only: income tax, payroll deductions, and mandatory savings schemes at a common gross salary. Housing in Dubai, Riyadh, Singapore, Hong Kong, and Zurich all sit at very different price points, and a market with a lower effective tax rate can still leave you with less spending power after rent than a higher-tax market with cheaper housing. Treat this article as the tax half of the decision and research cost of living for your specific city separately before comparing offers.
Do any of these five countries tax foreign or worldwide income?
Not for a standard employment-income scenario covered here. All five tax (or don't tax) salary earned for work performed in that country under a local employment contract. Worldwide income, investment income, and remote-work-from-abroad arrangements are separate questions with country-specific rules (and, for Switzerland in particular, can trigger residency-based worldwide taxation once you're tax-resident there) that sit outside the scope of a straightforward salary comparison like this one. If any of that applies to you, get local tax advice rather than extrapolating from this article.
Why isn't a country like the UK or Ireland included in this ranking?
Because this hub is specifically about the small set of markets that are genuinely tax-free or unusually low-tax for employment income, not a general global salary comparison. The UK and Ireland both run standard progressive income tax systems with meaningfully higher effective rates at senior tech salary levels, so they don't belong on a "tax-free and low-tax" list. If you're weighing a move between the UK or Ireland and one of these five markets specifically, our UK vs Switzerland and UK vs Australia comparisons cover that angle directly.
