People usually ask this rhetorically. A six point seven square kilometre territory on the end of Spain, thirty eight thousand people, a rock, some monkeys, and an argument that has run for three hundred years. What is it actually for? It is a fair question and it has a specific answer. Gibraltar is a door, and whoever holds the door has always been able to charge for it. The Mediterranean has one entrance from the Atlantic and this is it. There is no second route. If the [Strait of Gibraltar](https://en.wikipedia.org/wiki/Strait_of_Gibraltar) closes, the Mediterranean becomes a lake, and twenty two countries and something over five hundred million people lose their sea access in a single stroke. The traffic reflects that. Around **100,000 vessels** pass through the Strait every year, up to **400 a day** on the [International Maritime Organization's](https://www.imo.org/) figures, carrying somewhere near **twenty per cent of intercontinental maritime trade**. At the narrowest point Europe and Africa are fourteen kilometres apart. That is the whole explanation for why Gibraltar exists as a separate place. It was taken in 1704 because of the door, held through fourteen sieges because of the door, and every economic activity here since has been a variation on selling something to people passing through it. The modern economy is small, specialised and unusually productive. Estimates put GDP at roughly **2.4 to 2.7 billion pounds**, on a working population that fits in a large football stadium, with unemployment around **two to three per cent**. The [economy](https://en.wikipedia.org/wiki/Economy_of_Gibraltar) rests on four pillars. |Pillar|What it is|Why here| |Online gaming|Around a quarter of GDP and roughly 3,500 jobs|Early, credible regulation and English law| |Financial services|Banking, funds, insurance, wealth and DLT|A separate jurisdiction with EU proximity| |Shipping and bunkering|5,267 fuel calls in 2025|The door itself| |Tourism|Day visitors, cruise calls and short stays|The Rock, and duty free prices| Insurance is the quiet one. A large share of the motor policies written in the United Kingdom are underwritten from here, which is not something most British drivers know. The gaming sector is the loud one, employing about 3,500 people, [many of them commuting in from Spain](https://en.wikipedia.org/wiki/Economy_of_Gibraltar). The port is the oldest business on the list and it is growing. The [Gibraltar Port Authority](https://www.gibraltarport.com/bunkering) recorded 5,267 ship calls for fuel in 2025, and the first half of 2026 ran roughly 12 per cent ahead of the year before. Ships have been stopping here for supplies for three centuries. The commodity changed from water and salt beef to very low sulphur fuel oil. The logic did not. For a business, the attraction is the tax position and the legal system rather than the weather. Corporation tax is a flat **15 per cent** on profits accrued in or derived from Gibraltar, assessed on a [territorial basis](https://taxsummaries.pwc.com/gibraltar/corporate/taxes-on-corporate-income), so genuinely foreign profit generally falls outside the charge. There is **no VAT**, **no capital gains tax**, no tax on dividends and no wealth tax. The legal system is English derived and the working language is English, which removes a layer of friction for a London or Singapore parent that would otherwise be translating contracts. [Gibraltar Finance](https://www.gibraltarfinance.gi/) is the government body that exists to explain this to prospective firms. For an individual with substantial means there is [Category 2 status](https://www.gibraltarlaw.com/expertise/private-client/category-2-status-in-gibraltar/), where tax is charged only on the first 118,000 pounds of income with a cap of 42,380 pounds. Note the change: the minimum net worth for new applicants rose to **5 million pounds on 18 June 2026**, up from 2 million, with existing holders grandfathered at the old threshold. If you were told 2 million, that advice is out of date. For everyone else the benefits are more ordinary and arguably more useful. Pounds sterling. English spoken natively. Three hours flying from London. No VAT on the high street. A health service, a legal system and a school system that a British family recognises immediately, in a place with roughly three hundred days of sun. This is the objection that follows the benefits, so it is worth meeting rather than dodging. Gibraltar charges corporation tax at 15 per cent. That is a real rate on real profit, it is the same figure as the OECD global minimum, and it is higher than Ireland's headline rate. It is not zero and it has not been zero for a long time. Gibraltar exchanges tax information, sits inside the international transparency framework and was removed from the relevant grey lists. The fair criticism is different and worth stating honestly. A territorial system means profit earned outside Gibraltar generally escapes Gibraltar tax, and a small
