Closely related election tax charge concept.

Stop Charging Tax to Yourself

I was sitting in my office last Tuesday, staring at a stack of crumpled receipts that looked like they’d been salvaged from a shipwreck, when a client finally confessed he’d merged two of his businesses without a single piece of paperwork. He thought he was being efficient, but he’d actually walked right into a tax trap because he didn’t realize he needed to file a closely related election. People think these kinds of elections are some high-level corporate maneuver for the big players, but the truth is, it’s usually just a necessary safety net for small business owners who are growing faster than their paperwork can keep up.

I’m not here to bore you with the dense, legalistic jargon found in the CRA manuals. Instead, I’m going to give you the plain-English version of what a closely related election actually does and, more importantly, how to avoid the massive headache of doing it incorrectly. My goal is to give you the practical, no-nonsense roadmap I wish my clients had in their hands years before they ended up sitting across from me, trying to fix a mistake that should have been a simple checkbox.

Navigating Section 156 Tax Election Rules Before They Bite

Here is how you actually handle this without losing your mind. When you’re moving assets or services between two companies you own, you can’t just wing it. The CRA looks at these movements with a very skeptical eye, looking for any attempt to shift profits around to dodge a tax bill. This is where the section 156 tax election rules come into play. Essentially, these rules allow you to treat those related companies as a single unit for certain tax purposes, but there is a catch: you have to actually ask for it by filing the right paperwork before the year ends.

If you wait until you’re sitting in my office trying to explain why Company A “sold” a piece of equipment to Company B for fifty cents, you’re already behind the eight ball. Proper intercompany transaction compliance isn’t just about having a clean spreadsheet; it’s about making sure the election is documented and filed correctly the first time. If you miss the window, you’re stuck dealing with the tax consequences of two separate entities rather than the streamlined single-unit approach you actually wanted. Don’t wait for an audit to realize you missed a deadline.

Here is where things usually get messy. When you have two or more companies that are essentially siblings or part of the same family tree, the CRA doesn’t just take your word for it that they are “separate.” If you aren’t careful with your intercompany transaction compliance, you might find yourself in a position where the government decides your various entities are actually one single taxpayer. This isn’t just a technicality; it means you could lose the ability to flow losses from one side of your business to the other, or worse, find that your carefully planned tax structure has effectively collapsed under scrutiny.

The real danger lies in the “oops” factor. Many owners think they can just move money around between their holding company and their operating company whenever they feel like it. But without following the specific related party election requirements, those transfers can trigger unexpected tax hits that feel like they came out of nowhere. I’ve seen too many clients realize—usually during an audit—that they’ve been treating their corporate structure like a personal piggy bank, only to find out that the taxation of closely related entities is much more rigid than they ever imagined.

Five Ways to Keep the CRA From Treating Your Separate Businesses Like One Giant Piggy Bank

  • Don’t wait for an audit to check your connections. If you’re sharing staff, office space, or even just a common bank account between two companies, the CRA is going to look at them as one unit. You need to decide if you’re making that election before they decide it for you.
  • Get your paperwork in order before you move assets. If you’re transferring property or equipment from one of your corporations to another, you can’t just “wing it” with a handshake. You need a formal election to ensure you aren’t triggering a massive tax hit that you can’t undo later.
  • Watch your “control” definitions like a hawk. In the world of closely related corporations, “control” isn’t just about who owns 51% of the shares; it’s about how the entities function together. If they act like one business, the tax man will treat them like one business.
  • Keep your receipt shoeboxes separate. I know, I know—it’s tempting to run everything through one main account to save on bank fees, but mixing your business expenses across closely related entities is a fast track to a headache during filing season.
  • Treat the election like a permanent decision. These aren’t “oops, let me change that” kind of rules. Once you make an election regarding closely related corporations, you’re essentially locking in a specific tax treatment. If your business structure changes in two years, you might find yourself stuck in a setup that no longer makes sense.

The Bottom Line: Don't Let Paperwork Become a Penalty

If you’re thinking about merging operations or shifting assets between two businesses that feel like “one and the same,” don’t just wing it; you need to file that election before the CRA decides they’re separate entities and starts sending you bills.

The “closely related” label isn’t just a suggestion—it’s a legal trapdoor that can trigger unexpected tax hits if you haven’t properly documented the relationship from the jump.

Treat this like a curling stone; if you don’t set your line early and get the election in place, you’re going to spend the next three years playing catch-up with an auditor instead of running your business.

Don't Wait Until the Audit Notice Arrives

At the end of the day, managing closely related elections isn’t about mastering the entire Excise Tax Act; it’s about recognizing when your different business arms are starting to look like a single entity to the CRA. You need to keep a sharp eye on your ownership structures, track those common control links, and—most importantly—ensure you aren’t accidentally triggering a massive tax bill by failing to file the right paperwork when you merge or restructure. If you treat these elections as an afterthought, you’re essentially leaving a paperwork landmine in your backyard, just waiting for a tax auditor to stumble over it. Get the election in writing and get it done early.

I know it feels like just another layer of bureaucracy standing between you and actually running your business, but please, don’t let a preventable filing error eat your hard-earned margins. You didn’t get into this industry to become a part-time tax scholar, and you shouldn’t have to. My goal is to see you spending your time growing your company, not frantically digging through a shoebox of receipts trying to explain a structural mistake to a government agent. Take the time to set your foundation right now, and you won’t have to spend the next three years paying for the privilege of fixing it.

Frequently Asked Questions

If I've already started running two separate businesses under different names, can I still file this election, or is it too late?

The short answer is: yes, you can usually still file it, but you’ve already missed the “easy” window. Since you’re already operating, we aren’t just setting up a rule; we’re asking the CRA to recognize a relationship that’s already been functioning in the wild. It’s a bit like trying to fix a leaky roof while it’s already raining. We can file the election, but we need to be very careful about how your books have looked up to this point.

Does making this election mean I'll be paying more in total tax, or is it actually going to save me money on my year-end filing?

It’s not a magic wand that makes taxes disappear, but it’s usually a tool to prevent a massive, unnecessary bill. Think of it this way: you aren’t necessarily paying less tax overall, but you are choosing how and when you pay it. Without the election, the CRA might treat your businesses as one giant bucket, potentially triggering a tax hit you weren’t prepared for. It’s about control and avoiding a very expensive surprise.

What happens if I accidentally trigger a "closely related" status without realizing it—how do I know if the CRA is already looking at my two companies as one?

If the CRA starts treating your two companies as one, you’ll see it in the paperwork. They won’t send a friendly “heads up”; they’ll send a notice of reassessment or an audit letter where they’ve combined your income or disallowed a deduction you thought was safe. Usually, it starts when they notice shared directors, the same business address, or a suspiciously overlapping client list. If they’re asking questions about “common control,” you’re already in the thick of it.
