Who administers retail sales tax for Ottawa businesses?

Retail sales tax on most goods and services sold in Ottawa is administered federally as GST/HST by the Canada Revenue Agency. For Ontario-specific context and the historical Retail Sales Tax (RST), the provincial Ministry of Finance provides background on HST implementation and administration. Municipalities including the City of Ottawa handle business licensing, permits and bylaw enforcement but do not collect GST/HST directly.

Municipal licences do not replace federal GST/HST registration and remittance obligations.

Penalties & Enforcement

Enforcement of GST/HST remittance is led by the Canada Revenue Agency; the City of Ottawa enforces municipal licensing and business bylaw compliance where applicable. Below are the enforcement elements you must consider.

  • Fine amounts: federal late-filing and remittance penalties and interest are set by the CRA and described on its pages; specific dollar amounts or percentage rates should be confirmed on the CRA site.
    See the CRA resource for exact penalty formulas and interest rates.[1]
  • Escalation: initial penalties, higher repeat-offence penalties and ongoing interest are applied by CRA; details are provided on CRA guidance (not specified on the cited Ottawa page).[1]
  • Non-monetary sanctions: CRA may assess audits, reassessments and garnishment actions; municipal sanctions may include licence suspension or provincial offences under City bylaws (amounts and procedures are on municipal pages or the Provincial Offences Act where referenced).[3]
  • Enforcer & complaints: CRA handles tax compliance and collections; the City of Ottawa By-law and Business Licensing teams handle municipal infractions and licensing complaints (see City contact pages).[3]
  • Appeals & review: federal objections and appeals to CRA decisions follow CRA objection and appeals processes and prescribed time limits; municipal licence decisions have municipal review/appeal routes or judicial review where available (check the specific decision notice for time limits).
Keep complete sales records for at least six years to meet federal and municipal review requirements.

Applications & Forms

Registering for GST/HST, filing returns and remitting are handled via CRA forms and online services. Municipal licences use City of Ottawa application forms and online portals.

  • GST/HST registration: apply online through the CRA business registration service or via form RC1; check CRA for current submission methods and any fees (CRA page lists forms and steps).[1]
  • City business licence applications: use the City of Ottawa online licence portal for vendor, retail or temporary event licences; fees and deadlines are published per licence type on the City site.[3]
If you sell taxable goods or services in Ottawa and are unsure whether to register, seek CRA registration guidance immediately.
