How Gibraltar corporate tax works
Gibraltar charges a flat 15% corporation tax on assessable profits under the Income Tax Act 2010, a rate that has applied since 1 July 2024 (up from 12.5% before that date). There are no brackets, no small-profits rate and no marginal relief — a company with £10,000 of profit and a company with £10 million of profit both pay the same 15% headline rate on their Gibraltar-source income. The one exception is a higher 20% rate, which applies to a narrow set of sectors: utility and energy companies supplying electricity, fuel and water; companies that enjoy or abuse a dominant market position; and telecommunications companies, on their telecom-service income specifically (their other income is still taxed at 15%).
The rate itself is straightforward. What actually determines how much tax a company pays is the basis on which Gibraltar taxes profits in the first place — and that is where most calculators and guides go wrong.

Gibraltar operates on a territorial basis of taxation. Rather than taxing a company on its worldwide income, as many larger jurisdictions do, Gibraltar taxes only profits accrued in and derived from Gibraltar. This is not just a technicality — it is the single most important feature of the system. It means the tax authority looks at where the profit-generating activity actually happens (where contracts are concluded, services performed, staff and decision-makers based) rather than simply where the company happens to be incorporated or where its bank account sits. Genuine foreign-source profits that are not accrued in or derived from Gibraltar generally fall outside the Gibraltar tax net entirely, even for a Gibraltar-incorporated company.
Worked example: £100,000 in Gibraltar-source profit
Take a Gibraltar company with £100,000 of profit accrued in and derived from Gibraltar, taxed at the standard rate:
- Taxable profit: £100,000
- Corporation tax: 15% × £100,000 = £15,000
- Profit after tax: £100,000 − £15,000 = £85,000
- Effective rate: £15,000 ÷ £100,000 = 15%
No further national, local or surcharge layer is added on top — £15,000 is the final Gibraltar corporation tax bill on that profit, subject to any capital allowances or loss relief the company can claim. If the same £100,000 of profit instead came from a utility, energy or dominant-position business (or from telecommunications services specifically), it would be taxed at 20% instead, giving a bill of £20,000 rather than £15,000 — a difference worth checking carefully before assuming the standard rate applies.
Why the territorial basis matters
The accrued-in-and-derived-from-Gibraltar test has real consequences for how a company is structured and where its profit actually sits for tax purposes:
- Trading companies that genuinely operate from Gibraltar — with staff, management and contracts concluded locally — are squarely inside the Gibraltar tax net on that trading profit, and the 15% (or 20%, for the sectors above) applies in full.
- Holding companies receiving dividends, interest or gains from activities carried on outside Gibraltar can fall outside the Gibraltar tax net on that foreign-source income, since it is neither accrued in nor derived from Gibraltar, even though the holding vehicle itself is Gibraltar-incorporated.
- The test is applied to the source and location of the activity, not to nationality, residence or the currency used, which is why the analysis has to be done income stream by income stream rather than assumed for the company as a whole.
No local or municipal tax on top
Beyond the 15%/20% corporation tax itself, Gibraltar keeps its company tax system deliberately simple: there is no VAT, no capital gains tax, and no local, municipal or trade tax layered on top of the national charge. No solidarity surcharge, no regional multiplier, no second filing to a separate authority — corporation tax, administered by the Gibraltar Income Tax Office, is the only recurring tax most companies need to plan around. The one additional layer that can apply is the Global Minimum Tax Act 2024, which introduces a Qualifying Domestic Minimum Top-Up Tax and an Income Inclusion Rule with a 15% effective floor — but this is scoped only to large multinational groups with consolidated revenue of at least EUR 750 million, and does not touch ordinary companies below that threshold.
What most calculators and guides miss
Most Gibraltar tax tools stop at “15%” and move on, treating the rate as if it applied to a company’s total income the way a worldwide-taxation system would. That glosses over the point that actually determines the tax bill for many real businesses: the territorial, accrued-in-and-derived-from test that decides which profits are even in scope in the first place. A second common gap is the 20% sectoral rate — guides that quote a single flat 15% for every company miss that utility, energy, dominant-position and telecoms businesses are taxed differently, which is not a rounding error but a full third more tax on the same profit. This calculator applies the correct rate for your company type and keeps the territorial basis front and centre, rather than presenting Gibraltar as a simple single-number flat-tax jurisdiction.
