Setting Up a Limited Company: Step-by-Step

A limited company can offer credibility, limited liability, and tax-planning flexibility. It also brings more admin, including company accounts, Corporation Tax, confirmation statements, payroll decisions, and director responsibilities.

Before incorporation, decide the company name, registered office, directors, shareholders, share structure, SIC codes, and articles of association. These choices can affect banking, tax, investment, and future ownership changes.

Most companies need Corporation Tax registration. VAT and PAYE depend on turnover, staffing, and director salary decisions. Registering too late can create penalties; registering too early can create unnecessary admin.

Open a separate business bank account, choose bookkeeping software, keep invoices and receipts, and set calendar reminders for Companies House and HMRC deadlines. Cleaning up records after the first year usually costs more than getting the setup right early.

Write down who will own the company, who will be a director, how decisions are made and what happens if an owner leaves. A one-share formation may be fine for a single owner, but it can be awkward when co-founders, different economic rights or investment are expected.

Standard articles do not replace a founders or shareholders agreement. Obtain legal advice where vesting, intellectual property, deadlock, minority protection or a future sale matters. Correcting a casual share issue later can create legal and tax work.

Choose an allowable name, registered office, appropriate email address and SIC code, and identify directors, shareholders and people with significant control. Companies House identity-verification requirements now affect directors and relevant people; follow the current GOV.UK route and keep personal codes secure.

The registered office is public. It must meet the legal address conditions and be monitored so official mail is not missed. If privacy is important, consider a compliant address service before incorporation rather than changing the record after personal details have appeared.

Open a company bank account, issue and record the shares, create statutory registers, document director decisions, choose bookkeeping software and set approval rules for spending. Transfer contracts and intellectual property intentionally; incorporation does not automatically move a sole trade’s assets or obligations into the company.

Tell HMRC when the company becomes active for Corporation Tax and consider PAYE and VAT based on actual plans. Agree how directors will take money before withdrawals begin. Salary, dividends, expense reimbursements and director loans require different records and tax treatment.

Companies House accounts, the confirmation statement, Corporation Tax payment and the Company Tax Return have different dates. The first accounting period can also produce dates that look unfamiliar. Use the dates shown in the company register and HMRC account rather than counting from memory.

Use the company name and number on contracts and invoices, pay company costs from company funds and record any personal payment or withdrawal. Reconcile director-loan balances regularly. Limited liability is not a reason to mix money or sign personal guarantees without understanding them.

Before the first year end, reconcile the balance sheet, check payroll and dividend records, review open invoices and stock, and confirm the accounts and tax-return timetable with whoever will prepare them.
