UK filing deadlines explained
The key dates most founders need to understand.
Accountup Check starts with Companies House data, then the compliance calendar can map the wider year ahead when VAT and payroll apply.
Annual accounts
Your annual accounts are the yearly financial summary filed with Companies House. Filing late triggers automatic penalties, starting at GBP 150 for private limited companies.
Confirmation statement
This confirms that the company details held by Companies House are accurate. It is usually due once every 12 months.
Corporation tax return
Your CT600 corporation tax return is usually due 12 months after the accounting period end. The tax payment date is earlier, so directors should not wait until the return deadline.
VAT returns
VAT return dates depend on your VAT scheme and period end. Quarterly and monthly VAT returns are generally due one month and seven days after the period end.
PAYE and NI
If you run payroll, electronic PAYE and National Insurance payments are normally due by the 22nd of each month.
P11D forms and payment
If you provide non-cash employee benefits, P11D and P11D(b) forms are due by 6 July, with Class 1A National Insurance due by 22 July.
FAQ
How Accountup Check gets its information.
Where does the company information come from?
Accountup Check uses public company information from Companies House. That includes filing deadlines, company status, registered details, filing history, and officer information that already appears on the public register.
Do you see my company finances or bank data?
No. We do not access bank accounts, accounting software, tax accounts, payroll records, or private financial information. The snapshot is built from public Companies House data and the answers you choose to provide.
How current is the information?
We fetch the latest available public register data when you run a check. Companies House records can change after filings are accepted or processed, so the official register remains the source of truth.
How do I check a company?
Enter a UK company number if you know it, or search by company name. We will take you to a plain-English snapshot of that company’s filing position.
