Management Fees Between Related Companies: The Tax Risk Ontario Owners Should Know

Owners with more than one corporation — an operating company and a holding company, or a group of related businesses under common ownership — often use management fees to move money between them. One corporation performs work for another (administration, staffing, executive oversight) and charges a fee for it, which is deducted by the paying corporation and reported as income by the receiving one. Done properly, this is a legitimate and common business arrangement. Done loosely, management fees between related companies are one of the more frequently challenged deductions the CRA looks at, precisely because the parties aren't dealing with each other at arm's length.

The risk isn't that intercompany fees are prohibited — they aren't. The risk is that a fee unsupported by real services and real documentation looks less like a business expense and more like an attempt to shift income from one corporation to another for tax reasons alone.

Why the CRA Looks Closely at These Arrangements

When two corporations are related — commonly owned or controlled by the same person or group — there's no independent counterparty pushing back on the price, the scope, or whether the service was even needed. An arm's-length business negotiates a fee with someone who has their own incentive to question it. Related corporations don't have that natural check, which is exactly why the CRA applies extra scrutiny to whether a management fee reflects a real, reasonably priced service rather than a bookkeeping entry designed to move income to whichever corporation benefits most from the deduction.

What Makes a Management Fee Defensible

• A written intercompany management or services agreement. The agreement should describe what services are being provided, by whom, and on what basis the fee is calculated — before the fees start flowing, not reconstructed afterward.
• Services that are actually rendered. There should be real work behind the fee: administrative support, financial management, staffing, executive time, or similar services genuinely performed for the paying corporation's benefit.
• A fee that reflects fair value for the work. The amount charged should be comparable to what an unrelated party would reasonably charge for the same scope of services — not an amount chosen simply to move income to a lower-taxed corporation or to absorb a loss elsewhere in the group.
• Contemporaneous documentation of the work performed. Time records, invoices with enough detail to show what was delivered, correspondence, and reports all help demonstrate that the fee tracks real activity.
• Consistent treatment over time. A fee structure that changes dramatically from year to year, especially in a way that conveniently offsets a profitable or loss year elsewhere in the group, invites questions about its underlying purpose.

A Documentation Checklist

• [ ] Signed management or services agreement between the corporations
• [ ] Description of services covered and how the fee is calculated
• [ ] Records showing the services were actually performed (time logs, deliverables, correspondence)
• [ ] Invoices issued and paid in the ordinary course, not accrued and forgotten
• [ ] A basis for the fee amount that could be explained to a third party (comparable market rates, allocated cost plus a margin, or similar)
• [ ] Consideration of GST/HST on the intercompany charge, including whether the corporations qualify for an available election that can simplify tax on supplies between certain closely related corporations

The GST/HST Layer

A management fee charged between corporations is generally a taxable supply, meaning GST/HST considerations apply on top of the income tax question. Certain closely related corporations may be able to jointly elect to treat some intercompany supplies differently under the Excise Tax Act, which can simplify the GST/HST mechanics — but the conditions for that election are specific and it doesn't apply automatically. Whether your group structure qualifies is worth confirming with a professional rather than assuming.

What Happens If CRA Disagrees With the Fee

If the CRA concludes a management fee wasn't reasonable, or that the underlying services weren't genuinely provided, it can deny the deduction to the paying corporation. Because the receiving corporation has typically already reported the fee as income, a successful challenge can leave both sides of the transaction adjusted — the payer loses the deduction, while the income already reported on the other side doesn't automatically reverse. That two-sided exposure is one of the reasons this area deserves attention before the fees are set, not after a reassessment arrives.
