International expansion is rarely just a matter of registering a company in another country. The commercial opportunity has to be considered alongside corporate structure, tax, employment, immigration, intellectual property, contracts, data protection and local regulatory requirements.

The scale of the opportunity is significant. The UK had an estimated 5.7 million private-sector businesses at the start of 2025, with small and medium-sized enterprises representing 99.85 per cent of the business population.[1] In Ireland, the business economy contained 401,359 active enterprises in 2023, of which 99.8 per cent were SMEs.[2] In Hungary, the Central Statistical Office recorded 825,421 active enterprises in December 2024.[3]

For a growing company, the right question is therefore not simply “Where should we incorporate?” but “What structure will support the next stage of the business?”

The International Expansion Checklist

1. Commercial Strategy

Before entering the UK, Irish or Hungarian market, establish:

* target customers and market size;

* the competitor landscape;

* the pricing and distribution model;

* local partners or suppliers; and

* expected investment and operating costs.

2. Corporate Structure

Consider whether you require a subsidiary, a branch, a locally incorporated company or another operating structure. Review ownership, director responsibilities, shareholder arrangements and the relationship between the parent and the overseas entity.

3. Legal and Regulatory Review

Identify the laws applying to your sector before committing to market entry. These may include company law, licensing, consumer protection, competition rules, employment legislation and sector-specific regulation.

4. Tax and Finance

Map corporation tax, VAT, payroll, withholding taxes and any permanent-establishment risk. Cross-border transactions should also be reviewed for transfer-pricing and reporting implications.

5. Employment and Immigration

If employees or founders will relocate, assess the relevant immigration route, right-to-work requirements, employment contracts, payroll obligations and local employment protections. Ireland and Hungary are both EU and EEA member states, so free movement rules apply to EEA nationals moving between them; UK nationals generally require permission to work in either, and EEA nationals generally require permission to work in the UK.

6. Intellectual Property and Data

Check whether trade marks, patents and other intellectual property rights require territorial protection: UK rights and EU rights have been separate since the end of the Brexit transition period, so a single filing will not cover both. For personal data, assess the applicable UK and EU data protection regimes before transferring information internationally.[4] The UK regime was amended, but not replaced, by the Data (Use and Access) Act 2025, whose data protection provisions are now in force and which reworded the test applied to transfers of personal data outside the UK.[5]

7. Governance and Compliance

Set clear reporting lines between the parent and the overseas entity. Maintain statutory records, board approvals, beneficial ownership information and ongoing filing obligations.

What to Consider by Location

* United Kingdom. Review Companies House requirements, corporate structure, tax, employment, data protection and sector regulation. Note that identity verification at Companies House became mandatory on 18 November 2025 for newly appointed directors and people with significant control, with existing directors required to supply a verified personal code with the company’s first confirmation statement filed after that date.[6]

* Scotland. Company law is reserved to the UK Parliament, so a company incorporated in Scotland is registered at Companies House and governed by the Companies Act 2006 in the same way as one incorporated in England and Wales.[7] Scotland is nonetheless a separate legal jurisdiction with its own courts and its own law of property, contract, security and civil procedure. Commercial leases, security over assets, employment tribunal practice and dispute resolution should all be considered on a Scottish-law basis where relevant.

* Dublin, Ireland. Consider Irish company law under the Companies Act 2014, Revenue requirements, VAT, employment rules and EU regulatory obligations.[8] Ireland’s digital business environment is also developing quickly: more than 20 per cent of Irish enterprises used artificial intelligence in 2025, up from over 15 per cent in 2024, and 58 per cent of large enterprises did so.[9]

* Budapest, Hungary. Assess Hungarian company law, which is contained principally in Book Three of Act V of 2013 on the Civil Code, together with tax, employment and EU regulatory requirements.[10] Budapest had 414,288 registered enterprises in December 2024, which gives some indication of the scale of its commercial ecosystem.[11]

International expansion should be treated as a governance and commercial planning exercise, not simply an incorporation project. An expansion checklist should be completed before significant capital is committed, long-term contracts are signed or key personnel are relocated.

The strongest approach is to work through market, then structure, regulation, tax, people, intellectual property, data and governance in turn, and then to establish which of those issues require local professional advice.

This article is general information about international expansion and is not legal, tax or immigration advice. Specific advice should be taken in each relevant jurisdiction.
