UK LTD Company Accounting Requirements: A Guide for Polish Entrepreneurs 2026
<![CDATA[
Understanding UK LTD Accounting Obligations
If you’re a Polish entrepreneur running a UK Limited company, understanding the accounting landscape is critical. The UK system differs significantly from Poland’s — but with the right guidance, it can be simpler and more cost-effective.
At Semper Paratus Legal House LLP, we handle accounting for hundreds of Polish-owned LTDs, ensuring full compliance with both Companies House and HMRC requirements.
Key Filing Deadlines
Every UK LTD has two main annual obligations:
- Annual Accounts — filed with Companies House within 9 months of your accounting reference date
- Company Tax Return (CT600) — filed with HMRC within 12 months of your accounting period end
- Confirmation Statement — filed annually with Companies House to confirm your company’s details are up to date
Missing deadlines can result in penalties starting from £150 and escalating quickly.
What’s Included in Our Accounting Service
Our monthly accounting package (starting from 400 PLN/month for a company without employees) includes:
- Monthly bookkeeping and transaction categorization
- Annual Accounts preparation and filing with Companies House
- CT600 Corporation Tax Return to HMRC
- Confirmation Statement (CS01) filing
- VAT returns (if registered)
- Dedicated Polish-speaking accountant
Corporation Tax in the UK vs Poland
UK Corporation Tax currently stands at 19% (rising to 25% for profits over £250,000). Compare this to Poland’s 19% CIT or the 12%/32% PIT scale — the difference becomes significant for growing businesses.
Additionally, the UK offers:
- Full dividend tax credit system
- R&D tax credits for qualifying activities
- Annual Investment Allowance for capital expenditure
- No mandatory audit for small companies
