Understanding intercompany transactions and tax rules.

Money Moving Inside a Group Still Has Tax Rules

I was sitting across from a client last Tuesday—a lovely woman running a successful landscaping outfit—and she looked absolutely defeated. She’d been moving funds between her holding company and her operating company for years, treating the two bank accounts like one big communal purse. When I looked at her books, it wasn’t just a mess; it was a disaster waiting for an audit. Most people think that because you own both companies, moving money between them is just internal housekeeping, but when it comes to intercompany transactions and tax, the CRA doesn’t see it that way. They see a lack of documentation, and they see a massive opportunity to levy penalties that could sink your cash flow.

I’m not here to give you a lecture on theoretical accounting principles or bury you in jargon that requires a law degree to decode. My goal is to give you the straight talk I wish my clients had heard years before they ended up in my office with a shoebox full of excuses. I’m going to show you exactly how to structure these movements so you stay compliant, keep your paper trail clean, and—most importantly—stop leaving your hard-earned money on the table for the taxman to claim.

Why Your Transfer Pricing Documentation Requirements Are Failing

Why Your Transfer Pricing Documentation Requirements Are Failing

Most of my clients fail at this because they treat their various business entities like personal piggy banks. They think that because they own both Company A and Company B, the rules of physics—or at least the rules of the CRA—don’t apply. They move cash around to cover a payroll gap or shift a piece of equipment between entities, and they do it with nothing more than a handwritten note or a vague memo. This is where the wheels fall off. If you aren’t following the arm’s length principle compliance, you aren’t just being messy; you’re creating a massive red flag for an audit.

The real headache starts when you realize that “because I said so” isn’t a valid defense for your transfer pricing documentation requirements. If you’re charging your subsidiary for management time or setting intercompany loan interest rates that look more like a gift than a business deal, you’re asking for trouble. You can’t just pick a number out of thin air because it makes your year-end balance sheet look prettier. You need a paper trail that proves you’re acting like two strangers would in a real market transaction.

The Truth About Arms Length Principle Compliance

Here is the reality: the CRA doesn’t care that you and your sister-company are “family.” When it comes to arm’s length principle compliance, they view your various entities as total strangers. You can’t just decide to charge your subsidiary zero percent interest on a massive loan because you’re feeling generous this quarter. If a bank wouldn’t have offered that same deal to a stranger, then the taxman is going to flag it. I see it all the time—business owners thinking they can move profits around to wherever the tax hit is lowest, but they forget that every single move needs to look like a standard, market-driven deal.

This is where the math gets tedious. Whether you are dealing with cross-border intra-group services or just shifting equipment between two local shops, you have to justify your numbers. You can’t just “wing it” with a napkin calculation. If you haven’t benchmarked your intercompany loan interest rates against what a real lender would charge, you’re essentially leaving a trail of breadcrumbs for an auditor to follow. It isn’t about being difficult; it’s about proving that your business isn’t just a shell game designed to dodge the rules.

Five Ways to Keep the CRA Out of Your Internal Business Affairs

  • Stop treating your separate corporations like one big communal piggy bank. Just because you own both companies doesn’t mean the money belongs to both. If Company A pays a bill for Company B, you need a formal loan agreement or a reimbursement trail, or you’re looking at a nightmare of shareholder benefits and tax adjustments.
  • Get it in writing before the money moves. I see it all the time: a client moves a chunk of cash to their holding company and says, “We’ll figure out the paperwork later.” “Later” is usually when the audit happens. Draft a simple agreement that outlines interest rates and repayment terms now, while you’re still in the clear.
  • Watch your interest rates like a hawk. If you’re lending money between your companies, you can’t just do it at 0% interest because you’re feeling generous. The CRA expects an “arm’s length” rate—basically, what a bank would charge a stranger. If you don’t charge enough interest, they’ll come knocking to collect the difference.
  • Keep the receipts separate, even if it’s a pain. I have a running list of the worst shoeboxes I’ve ever seen, and half of them are a mess because owners mix personal, Company A, and Company B expenses into one pile. If you can’t tell which entity paid for which laptop, you’re asking for a headache you don’t need.
  • Document the “why” behind every major transfer. If you’re shifting profits or moving assets between entities, don’t just do it because it feels right at the moment. Write down the business reason for the transaction. If you can’t explain the logic to me in five minutes, you won’t be able to explain it to an auditor in five years.

The Bottom Line: Three Things to Fix Before Your Next Audit

Stop treating your various companies like one big shared wallet; if you’re moving cash or equipment between entities, you need a paper trail that looks like a real business deal, not a casual favor.

You can’t just pick a number out of thin air to justify what one company charges another—if you wouldn’t give that same price to a total stranger, the CRA won’t accept it either.

Documentation isn’t just “good practice,” it’s your only shield; if you haven’t written down the logic behind your intercompany pricing before the taxman asks, you’ve already lost the argument.

Getting Your House in Order

At the end of the day, managing intercompany transactions isn’t about performing complex mathematical gymnastics; it’s about discipline. You need to stop treating your various business entities like a single, giant piggy bank where you can just move funds around whenever the mood strikes. If you aren’t documenting your transfer pricing, maintaining an arm’s length approach, and keeping a paper trail that would satisfy a skeptical auditor, you aren’t just being “informal”—you are leaving yourself wide open to expensive penalties and reassessments. I’ve seen too many owners spend their weekends digging through messy digital folders trying to justify a transfer that happened eighteen months ago, only to realize the documentation simply doesn’t exist.

I know, it feels like a massive headache that pulls you away from the actual work that grows your business. But think of it this way: setting these rules up now is like sweeping the ice before a competitive curling match. It might feel tedious in the moment, but it’s the only way to ensure you don’t slip and crash halfway through the game. Get your systems in place today so that when tax season rolls around, you can focus on your actual growth instead of explaining to me why your books look like a jigsaw puzzle with half the pieces missing. You built these businesses to succeed, not to spend your life fighting the CRA.

Frequently Asked Questions

If I'm just moving money from my personal account to my corporation to cover payroll, do I still need to treat that like a formal loan with interest?

No, you don’t need to charge yourself interest for that. If you’re just injecting cash to cover payroll, that’s a shareholder loan—specifically, you’re lending money to the company. It’s a simple way to keep the lights on. Just make sure you track it clearly in your books so we don’t mistake it for revenue later. As long as you’re the one putting the money in, the CRA isn’t hunting for interest.

I have two separate companies—one for consulting and one for my equipment—how much "extra" can I actually charge one for using the other's stuff before the CRA starts asking questions?

Here’s the reality: there is no “magic number” or specific percentage that keeps the CRA off your back. If you charge your consulting firm $100 for equipment that actually costs $1,000 to rent on the open market, you’ve got a problem. You need to charge what a complete stranger would pay. If you can’t justify the rate with a quick market comparison, you’re just moving money around, and that’s a red flag.

What happens if I realize I've been doing these transfers all wrong for the last two years; do I have to go back and fix every single transaction?

Take a breath. You aren’t the first person to walk into my office with a “oops, I’ve been doing this wrong” look on your face.
