Choose the structure before registering

A sole trader and a limited company have different legal, tax and filing responsibilities. Consider risk, expected profit, ownership and administration before choosing.

  • Discuss sole trader versus company
  • Confirm who will own and manage the business
  • Separate personal and business banking

Map registrations and first deadlines

Revenue registration depends on your structure and activity. VAT and employer registration are not automatic in every case. A simple first-year calendar avoids relying on memory.

  • Income Tax or Corporation Tax
  • VAT where required or appropriate
  • Employer registration before payroll
  • CRO obligations for a company

Create an evidence trail from day one

Decide how sales invoices, purchase receipts, bank records and payroll changes will be stored and reviewed. Consistency matters more than a complicated tool.

  • Number and store sales invoices
  • Keep readable purchase evidence
  • Reconcile the bank regularly
  • Review cash flow before tax dates
