UK — Private Limited Company (Ltd)

The UK Private Limited Company (Ltd) remains one of the world's most recognised and straightforward corporate vehicles — a common-law entity with no minimum capital requirement, no residency restriction on directors or shareholders, and incorporation that is typically completed within 24 hours through Companies House. It is widely used as a holding company, an EU-adjacent operating entity, or a standalone trading vehicle for founders who want jurisdictional credibility without the complexity of a regulated license.

2026 brings the most significant change to UK company law in a generation: mandatory identity verification. Since 18 November 2025, every director and Person with Significant Control (PSC) must verify their identity with Companies House — either free via GOV.UK One Login, or through an Authorised Corporate Service Provider (ACSP) — before a new incorporation or appointment is valid. Existing officers have a 12-month transitional window ending 17 November 2026. Zitadelle AG is positioned to support this process as part of standard formation and ongoing compliance.

Mandatory identity verification.The Economic Crime and Corporate Transparency Act 2023 (ECCTA) moved identity verification from voluntary to mandatory on 18 November 2025. Every director, PSC, and LLP member must obtain a Companies House personal code, either through the free GOV.UK One Login service or via an Authorised Corporate Service Provider. Existing officers have until their company's next confirmation statement date, within a 12-month transitional window ending 17 November 2026, to comply. New incorporations and new appointments require verification immediately, at the point of filing.

ACSP filing requirement.From spring 2026, any third party filing on a company's behalf at Companies House must itself be a registered Authorised Corporate Service Provider — a formation agent, accountant, or solicitor supervised for anti-money-laundering purposes. This tightens who can legally handle formation and ongoing filings on a client's behalf.

Fee increases.Companies House fees rose again on 1 February 2026 — the digital incorporation fee doubled from £50 to £100, and the annual confirmation statement fee rose from £34 to £50. This is the second increase since May 2024, funding Companies House's expanded verification and enforcement powers.

Registered office rules tightened. PO Boxes are no longer acceptable as a registered office address. The address must be a location where documents can be delivered and an acknowledgment of receipt obtained.

UK corporation tax for the 2026/27 tax year operates on a tiered structure. Companies with taxable profits up to £50,000 pay the small profits rate of 19%. Companies with profits above £250,000 pay the main rate of 25%. Profits falling between these two thresholds are taxed at the main rate reduced by marginal relief, producing an effective rate that increases gradually across the band rather than jumping at either threshold. Thresholds are shared proportionally among associated companies and pro-rated for accounting periods shorter than twelve months.

Close investment-holding companies — a common structure for passive share or property holding among connected parties — pay the 25% main rate on all profits regardless of level, and do not qualify for the small profits rate or marginal relief. This distinction matters for anyone structuring a UK entity purely as a holding vehicle.

A UK Ltd company carries meaningful weight with international banks and payment institutions, particularly for businesses seeking credibility with EU, US, or Commonwealth counterparties. Banking access depends on the underlying business model, source of funds, and beneficial ownership transparency — a fully identity-verified structure under the new ECCTA regime is, if anything, an advantage in bank onboarding, since it aligns with what compliance teams are already required to check independently.

Ongoing compliance obligations include an annual confirmation statement (£50 statutory fee), annual accounts filing, Corporation Tax return (CT600), and — where turnover exceeds the £90,000 threshold — VAT registration and quarterly returns.
