Starting out

New business checklist for Ontario

The registrations, accounts and habits a new Ontario business needs in its first months, in the order they usually happen. Most items take an hour; the expensive ones are the ones left until a deadline has passed.

Items marked with a threshold or a deadline come from the linked CRA and Ontario pages. The rest is how we set up a new client.

Structure and registration

Structure and registration

  • Decide between a sole proprietorship and a corporation with your accountant and lawyer
  • Register the business name, or incorporate, through the Ontario Business Registry, and keep the company key
  • Choose a year-end date; December 31 is usual but not required for a corporation
  • Open a business bank account, and keep personal spending out of it from the first day
  • Minute book, share register and directors' resolutions set up, if incorporated
CRA accounts

CRA accounts

  • Business number from the CRA
  • Corporation income tax program account, if incorporated
  • GST/HST account: required within 29 days of exceeding $30,000 in taxable sales in four consecutive quarters or in one quarter; optional before that
  • Payroll account, before the first pay run
  • Import-export account, if goods will cross the border
  • CRA My Business Account set up, and your accountant authorised as a representative
Before the first hire

Before the first hire

  • Payroll account open and the remittance schedule known
  • TD1 federal and Ontario forms from each employee
  • CPP, EI and income tax deductions set up in the payroll system
  • WSIB registration where the business is required to register
  • Employee or contractor decided for each person, with the reasoning kept
  • Pay dates and the remittance dates that follow them on the calendar
Books and records

Books and records

  • Accounting system chosen and the chart of accounts set up for how you will run the business
  • Bank and credit card feeds connected; receipts attached to entries as they arrive
  • Sales invoices numbered, with the HST number shown once registered
  • A monthly close date agreed, and reconciliations done every month from month one
  • Records kept for six years from the end of the tax year they relate to
The first year's calendar

The first year's calendar

  • HST return dates for the reporting period the CRA assigns
  • Payroll remittance dates and the T4 deadline at the end of February
  • T2 return due six months after year-end; the balance owing is generally due earlier
  • Ontario annual return within six months of year-end, through the Ontario Business Registry
  • Instalments, once the CRA asks for them
  • An autumn planning conversation before the first year-end

This checklist describes general steps for a new Ontario business. It is not legal advice; incorporation, employment and licensing questions should go to a lawyer, and municipal licences vary by city.
