UK Company Compliance 2026: CS01 and Annual Account Deadlines
Owning a UK Limited Company (Ltd) is a prestigious way to do business, but it comes with strictly enforced legal obligations. For Arab directors managing their companies from Egypt, the Gulf, or elsewhere, missing a filing date is the most common cause of fines and company strike-offs. In 2026, with Companies House automating its penalty systems, staying on top of your deadlines is more critical than ever.
In this guide, Eteform.com outlines the key dates you must remember to keep your company in good standing.
1. Confirmation Statement (CS01)
This is a simple report confirming that your company’s public information (address, directors, shareholders) is correct. It is NOT a financial report.
- Due Date: Every 12 months from the date of incorporation.
- Deadline: Within 14 days of the due date.
- The Risk: Companies House will strike off your company if this is not filed, leading to the loss of your business name and bank accounts.
2. Annual Accounts
This is a financial report showing your company’s profit, loss, and assets. Even “Dormant” companies with no sales must file accounts.
- Deadline: 9 months after your financial year-end.
- Automatic Fines: If you are even 1 day late, an automatic £150 fine is issued. This increases to £1,500 for long delays.
3. Corporation Tax (CT600) and HMRC
Your tax return must be filed with HMRC.
- Filing Deadline: 12 months after your accounting period ends.
- Payment Deadline: Usually 9 months and 1 day after the period ends (Yes, you must pay the tax before the filing deadline!).
2026 Deadline Summary Table
| Obligation | Frequency | Key Deadline | Consequence of Delay |
|---|---|---|---|
| CS01 Filing | Annual | Anniversary + 14 days | Company Strike-off |
| Annual Accounts | Annual | 9 months after year-end | Automatic £150 – £1,500 fine |
| Tax Return (CT600) | Annual | 12 months after year-end | £100+ fine & interest |
| VAT Returns | Quarterly | 1 month + 7 days after quarter | Points-based penalties |

Frequently Asked Questions (FAQ)
A: Yes. You must still file a “Dormant CS01” and “Dormant Accounts.” The filing fees are the same, and the penalties for missing them are just as strict.
Q: Can I change my company’s “Year-End” date?
A: Yes, you can shorten or lengthen your accounting period once a year to align with your business cycle. Eteform can handle this update for you.
Q: What happens to my Wise account if my company is struck off?
A: Wise will receive a notification from the public register and will freeze your funds immediately. Restoring a company is a long and expensive process.
