UK LTD for Polish Entrepreneurs in 2026: Complete Guide to Registration & Compliance
<![CDATA[
Why Polish entrepreneurs choose a UK Limited Company
Polish entrepreneurs are increasingly turning to UK Limited Companies (LTDs) as a strategic business structure. The reasons are compelling: lower corporate taxes, simpler administration than a Polish sp. z o.o., access to the UK banking system, and — crucially in 2026 — protection against Poland’s new PIP reform that allows ZUS to reclassify B2B contracts as employment relationships.
But 2026 also brings significant compliance changes to UK company law. Here’s everything you need to know about registering and running a UK LTD as a Polish entrepreneur this year.
Key 2026 changes every LTD director must know
1. Companies House identity verification
Under the Economic Crime and Corporate Transparency Act (ECCTA), all company directors and Persons with Significant Control (PSCs) must now verify their identity with Companies House. This applies to both new registrations and existing companies. The verification can be done remotely through authorised service providers — including through Semper Paratus Legal House.
2. WebFiling closed for annual accounts
As of 31 March 2026, Companies House has permanently closed its WebFiling service for submitting annual accounts. All financial statements must now be filed through third-party software using the iXBRL format. This affects every single UK LTD — your accountant must be equipped with compatible software.
3. P&L disclosure — paused but not cancelled
The controversial proposal to make profit & loss accounts publicly visible was paused by the UK government in 2025 as “too burdensome.” However, it remains on the legislative agenda. Preparing transparent accounts now puts you ahead of the curve.
4. Making Tax Digital for Income Tax (MTD ITSA)
From April 2026, self-employed individuals and landlords earning above £50,000 must comply with MTD ITSA — digital quarterly reporting to HMRC. If your LTD pays you dividends or a director’s salary, this may affect your personal tax obligations.
What you need to register a UK LTD
- Company name — must be unique and not misleading
- Registered office address — must be a physical UK address (we provide this in our Premium package)
- Director details — at least one director (can be a Polish resident)
- Shareholder details — PSC information with identity verification ready
- SIC codes — describing your business activities
- Articles of Association — we provide model articles suitable for Polish entrepreneurs
Registration process step by step
