To legally share expenses like IT, human resources, or office space among related corporate entities, you must draft a formal Cost-Sharing Agreement. If structured properly as a pure reimbursement, or by filing a closely related corporate election with the Canada Revenue Agency (CRA), you can generally avoid paying punitive GST/HST markups on these intercompany transactions.
As corporate groups expand across Canada, maintaining separate administrative departments for every subsidiary becomes incredibly inefficient. 📍 Whether your headquarters is in Toronto, Vancouver, or Halifax, you likely have one parent company paying for shared software licences, centralized accounting, or a single massive commercial lease. Without a structured agreement, allocating these costs to your sister companies can accidentally trigger massive tax liabilities with the Canada Revenue Agency (CRA).
Many business owners mistakenly assume that because they own all the companies, they can simply move money around to cover bills. However, under Canadian tax law, each corporation is a distinct legal person. If Company A provides HR services to Company B, the CRA generally views this as a taxable supply subject to GST/HST (or QST in Quebec). A formal cost-sharing agreement, drafted with a corporate lawyer from our directory, ensures these transactions are legally recognized as pure reimbursements rather than taxable revenue.
Step-by-Step Process in Canada for Cost-Sharing Agreements
Properly setting up a cost-sharing structure requires careful coordination between your legal counsel and your accounting department. The goal is to prove that no profit is being made on the shared expenses.
Step 1: Determine the Corporate Relationship
Before drafting anything, you must map out exactly how your corporations are related. 🔍 The CRA provides specific tax relief for corporations that are “closely related”-meaning there is at least 90% common ownership of voting shares and value. If you meet this threshold, you unlock specific tax elections that simplify cost-sharing immensely across provincial borders.
Step 2: Draft the Cost-Sharing Agreement
You must establish a formal written contract between the participating corporations. This agreement must clearly outline which specific expenses (like rent, legal fees, or cloud storage) are being shared. It must also detail the exact allocation formula. For example, rent might be split based on the square footage each subsidiary uses, while IT costs might be divided by the number of employee workstations.
Step 3: Ensure “Pure Reimbursement” Status
To avoid charging GST/HST, the parent company must act strictly as an agent for the subsidiaries. 💰 This means the parent company pays the third-party invoice (like a massive software bill) and charges the subsidiary the exact fractional amount without a single cent of markup. If you add a 5% administrative fee to the shared cost, the CRA will classify the entire transaction as a taxable service.
Step 4: File CRA Form RC4616 (If Applicable)
If your companies are closely related and registered for GST/HST, you can formally elect to have intercompany supplies made for nil consideration. You must file Form RC4616 (Election or Revocation of an Election for Closely Related Corporations) with the CRA. Once processed, this legal election allows you to charge shared administrative fees or rent without having to remit GST/HST between your own entities.
How Much Does it Cost in Canada?
Setting up a legally compliant corporate structure requires upfront investment, but it saves millions in denied input tax credits and CRA penalties over time.
| Service / Filing | Estimated Cost (CAD) | Details |
|---|---|---|
| Corporate Law Firm Fees | $1,500 – $3,500+ | Drafting the formal Cost-Sharing Agreement and agency clauses. |
| CRA Election (RC4616) | $0 | The CRA does not charge a fee to file the closely related corporate election. |
| Accounting Review | $1,000 – $2,500 | CPA fees to verify your allocation formulas and set up intercompany ledgers. |
💼 Remember that if you operate in Quebec, you must file a separate but similar election with Revenu Québec to ensure you do not inadvertently trigger the Quebec Sales Tax (QST).
How Long Does the Process Take?
Drafting a standard agreement and establishing the allocation formulas typically takes a law firm 2 to 4 weeks. Once the agreement is signed, you must file the RC4616 election with the CRA before the first intercompany invoice is issued. The CRA processes these elections generally within 30 to 60 days, though they take effect from the date specified on the form.
Frequently Asked Questions (FAQ)
Do we need to charge interest on shared expenses?
Generally, if it is a pure reimbursement that is settled quickly (e.g., within 30 days), no interest is required. However, if the subsidiary leaves the balance unpaid for years, the CRA may recharacterize it as an intercompany loan, which must bear a commercial interest rate.
What happens if we add a markup to the shared costs?
If you add any markup to a shared cost, it is no longer a pure reimbursement. The CRA will view it as a management fee or commercial service. You will be legally required to charge and remit GST/HST on the total amount invoiced.
Can joint employment agreements replace cost-sharing?
Yes, for payroll. If an employee works for three related companies, you can draft a Joint Employment Agreement where all three companies are legally the employer. This prevents the CRA from claiming one company is “supplying” labour to the others, which would attract GST/HST.
Do we need a lawyer if we use the exact same directors?
Yes. Even if the directors and shareholders are exactly the same, the corporations are legally separate entities. A verbal agreement is extremely difficult to defend during a CRA sales tax audit. A written contract drafted by a law firm provides a critical paper trail.
Does this apply to cross-border Canadian and foreign companies?
No. The RC4616 election only applies to closely related Canadian corporations. If a Canadian parent shares costs with a US or European subsidiary, complex transfer pricing rules under the Income Tax Act apply, and you cannot simply use domestic cost-sharing exemptions.
