When must an LTD company file Annual Accounts and CT600?

Annual Accounts are usually filed with Companies House within 9 months of the end of the financial year, while the CT600 corporation tax return is filed with HMRC within 12 months of the end of the accounting period. Corporation Tax itself is normally payable 9 months and one day after the year end.

Does every LTD company need to register for VAT?

VAT registration becomes mandatory once turnover exceeds the statutory threshold, but many companies choose to register voluntarily earlier. We advise when registration is beneficial and prepare quarterly VAT returns in line with Making Tax Digital.

Do you run payroll for directors and employees?

Yes, we handle payroll under the PAYE scheme: calculating salaries and National Insurance contributions, producing payslips and submitting RTI reports to HMRC, for both single-director companies and larger teams.

Accounting for UK LTD Companies

Running an LTD company in the UK comes with a series of obligations towards Companies House and HMRC, whose deadlines and requirements are easy to miss while you focus on growing the business. Semper Paratus takes that responsibility off your shoulders, providing comprehensive accounting support tailored to British rules. From the first invoice to the annual accounts, we make sure your company files correctly, on time and in a tax-efficient way.

We work with entrepreneurs who have set up, or are planning to set up, an LTD company in the United Kingdom and want confidence that the financial and formal side of the business is in safe hands. We understand the reality of working remotely between the UK and abroad, and we explain the intricacies of British regulations in clear, practical language.

What LTD company accounting includes

Our service is complete and covers every statutory obligation of a company trading in the United Kingdom:

Bookkeeping – ongoing recording of sales and purchase invoices, bank reconciliation and organising your documentation so the figures are always ready for filing.
Annual Accounts – preparing and submitting the yearly financial statements to Companies House in the required format and on time.
CT600 – preparing and filing the Corporation Tax return with HMRC, together with the calculation of the tax due.
VAT returns – VAT registration where required or beneficial, and quarterly returns compliant with Making Tax Digital.
Payroll / PAYE – calculating salaries and National Insurance contributions, producing payslips and RTI reporting for directors and employees.
Confirmation Statement – the annual confirmation of your company's current details in the Companies House register.

If you also need direct representation, we offer settlements with authorities and broader tax settlement advisory.

Who it is for

We work with single-person directors, family firms and growing trading or service companies. We are particularly well suited to owners running a business from abroad while the company operates in the UK and needs an accountant who understands both contexts. Whether you are issuing your first invoices or employing a team, we adapt the scope of our services to the stage your business has reached.

How we work, step by step

Free consultation – we learn about your business, your current filings and your nearest deadlines.
Organising the data – we take over your documentation, set up a simple invoice flow and access to the systems we need.
Ongoing accounting – we keep the books, manage VAT and payroll, and alert you to upcoming obligations.
Annual filings – we submit the Annual Accounts, CT600 and Confirmation Statement, keeping you compliant with HMRC and Companies House.
