Gibraltar TIN number guide

Taxpayer reference number​

The Gibraltar Income Tax Office provides taxpayer reference numbers to individuals and corporate entities subject to taxation in Gibraltar. Functioning as the equivalent of a taxpayer identification number (TIN), these reference numbers are applicable to both income tax and corporation tax.

Gibraltar's taxpayer reference numbers, also recognized as taxpayer identification numbers (TINs), are comprised solely of numerical digits and are systematically assigned in chronological order. It consists of 6 digits.

Frequently Asked Questions​

Does getting a Gibraltar DLT licence mean all company profits are taxable in Gibraltar, even if clients are overseas?​

Yes. Gibraltar's Income Tax Act contains a "deemed to accrue" rule: any company carrying on a licensable activity under Gibraltar law — including a GFSC-issued DLT licence — has its profits deemed to accrue in and derive from Gibraltar regardless of where clients or counterparties are located. This means a DLT-licensed firm serving customers entirely outside Gibraltar is still subject to 15% Gibraltar corporation tax on those profits. Since the 2024 budget, interest income earned as a trading receipt by DLT-licensed firms is also deemed Gibraltar-sourced and fully taxable. Companies should factor this in before applying for a DLT licence as an offshore structuring tool. [1] [2]

Gibraltar replaced import duties with a Transaction Tax in April 2026 — what does this mean for goods businesses?​

From 10 April 2026, Gibraltar entered a customs union with the EU and replaced its import duty regime with a new Transaction Tax (TT) on goods. The TT starts at 15%, rising to 16% in year two and 17% in year three. A 5% reduced rate and a 0% super-reduced rate apply to certain categories (including children's items and essential goods such as food, medicines and electricity). Critically, the TT applies only to goods — services remain entirely outside its scope, so Gibraltar stays VAT-free for service-based businesses. Goods already on the Gibraltar market before 10 April benefit from a three-month sell-through period before EU product compliance rules are enforced. [3]

What are the actual qualifying conditions for Gibraltar's Category 2 tax status, and what trips up applicants?​

Category 2 (Cat 2) status caps income tax at a maximum of £42,380 per year (2025/2026), applied only to the first £118,000 of worldwide income. To qualify an applicant must: (1) have a minimum net worth of £2 million; (2) not have been resident in Gibraltar during the five years immediately preceding the application year; and (3) occupy approved residential accommodation in Gibraltar for the exclusive use of themselves and their family throughout the whole year of assessment. The accommodation — whether purchased or rented — must be approved by the Finance Centre Director via a "description of property" form submitted within two months of the qualifying certificate being issued. The Director has discretion to reject properties deemed not to meet the standard appropriate for a high-net-worth lifestyle. Failing the five-year non-residency bar or receiving a property rejection from the Director are the most commonly reported blockers. [4]

After Brexit, can Gibraltar-licensed financial services firms still passport into the EU or the UK?​

EU passporting was lost when Gibraltar left the EU on 31 January 2020. Gibraltar-licensed firms are now treated as third-country firms by EU member states and must obtain individual authorisation in each EU country where they wish to operate — there is no single-market shortcut. A unique UK–Gibraltar passporting arrangement was, however, preserved: Gibraltar-licensed financial services firms retain the right to passport their services into the UK market under a transitional regime currently extended until 31 December 2026, while a permanent framework is agreed. EU-headquartered firms that lose UK market access can establish a Gibraltar entity to regain it via this route, but the reverse — using a Gibraltar licence to reach the EU — no longer works. [5] [6]

What are Gibraltar's corporate tax return deadlines, and what penalties apply if a company files late?​

Corporation tax returns (Form CT1) must be filed within 9 months of the end of the accounting period under Section 29 of the Income Tax Act 2010. From 1 January 2025, late-filing penalties are tiered by company size. Micro/small businesses: £100 on the due date, rising by £450 after 3 months and a further £750 after 6 months. Medium businesses: £750 initially, £1,250 after 3 months, £2,000 after 6 months. Large businesses: £1,500, then £3,500, then £5,000. Late payment attracts a 10% surcharge, doubling to 20% after a further 90 days. For individuals, income tax returns are due 30 November each year; late filing costs £50, rising to £350 after three months and £850 after six months. [7] [8]
