Accounting for Plumbers: Is it Time to Incorporate?

Let’s be real—nobody enjoys thinking about a CRA audit. But if there’s one area the Canada Revenue Agency loves to zoom in on, it’s your meal and entertainment expenses. Why? It’s a notorious grey area where business spending and personal perks can get seriously tangled up, and the CRA knows it.

Picture this: you take a client out for a fantastic lunch. The conversation flows, you strengthen your relationship, maybe you even close a major deal. Awesome. You pay the bill, pocket the credit card slip, and mentally file it under ‘100% business write-off.’

Well, hold on a second.

That entire expense isn’t deductible. Not even close. In the eyes of the CRA, you can only claim 50% of it.

The 50% Rule: What’s the Deal?

So, what’s behind this rule? It’s actually pretty logical, in a government sort of way. The CRA acknowledges that you often need to spend money on food and fun to earn income. But they also know that, hey, you have to eat anyway. So, they meet you in the middle. You get to deduct half for the business portion, and the other half is considered a personal cost. It’s a firm rule with very few exceptions (like a staff party for all employees, but that’s a whole other can of worms).

This simple rule trips up so many business owners. And the mistake isn’t just about claiming the full amount.

Your Receipt is Almost Useless on Its Own

Here’s the real kicker. To even get that 50% deduction, you need way more than the flimsy little slip from the credit card machine. What does that piece of paper actually prove? Only that a transaction happened. It proves nothing about what the transaction was for.

To truly audit-proof your meal expenses, you have to tell the whole story. The CRA wants to see the full picture, and that means you need:

  • The Itemized Receipt: This is the bill that lists exactly what you bought. Was it two steaks and a salad, or two pitchers of beer and nachos? The details matter because they help paint a picture of a legitimate business meeting.
  • Who Was There: You’ve got to jot down the names of everyone who attended. Scribble it right on the receipt or add a note in your bookkeeping app. “Lunch with Sarah Smith from ABC Corp” is perfect.
  • The Business Purpose: Why did you meet? To nail down the Q1 sales strategy? To finalize a project? A simple note like “Discussed 2024 marketing budget” is all it takes. It connects the expense directly to your income-earning activities.

Without these three pieces of info, that credit card slip is just a piece of paper to an auditor. If you’re ever reviewed, the CRA could easily deny the entire expense, sticking you with a bigger tax bill and some unwelcome penalties.

It’s all about creating a crystal-clear paper trail. You’re showing the CRA, “Yes, this was a legitimate business expense, and here is all the proof you need.”

So, what can you do right now? Start with that pile of receipts from the last few months. Seriously, take 15 minutes today and start digitizing them. Use a simple phone app like Dext or Hubdoc to snap a picture, store the details, and finally get rid of the paper clutter.

Getting your day-to-day habits in order is a huge win, but tax rules can have tricky nuances that apply to your specific industry. If you’re looking at your own shoebox of receipts and wondering what else you might be missing, it’s always a good idea to chat with a professional. For personalized advice on your bookkeeping, tax strategy, and how to keep your business records truly audit-proof, you can always get in touch with an expert who can help clarify things for your unique situation.

Accounting for Plumbers - FAQs

If I incorporate, can I still pay myself easily or does all the money belong to the company?

Yes, you can absolutely pay yourself! While the money technically belongs to the company, you’re the owner, so you call the shots. You can pay yourself a regular salary (which makes you an employee of your own company), pay yourself dividends from the profits, or do a mix of both. Each option has different tax perks, and a good accountant can help you figure out the best strategy for you.

My spouse helps with the books and answering the phone. How does incorporation affect them and our family's finances?

Incorporation can be great for this. It opens up smart ways to do some income splitting. For instance, you could pay your spouse a reasonable salary for the work they actually do, which becomes a handy tax deduction for the business. You could also make them a shareholder, allowing them to receive dividends. The rules here are strict—the pay has to match the work—but it can be a fantastic way to improve your family’s overall tax picture.

Are there specific government grants from CanNor or territorial programs that are only available to incorporated businesses?

Yes, very often. Many of the bigger grants for business development and expansion are specifically designed for formal business structures. While some programs are open to sole proprietors, being incorporated makes you eligible for a much wider range of funding and frankly, makes your application look more solid and professional to the people handing out the money.

What's a realistic all-in cost to set up and maintain a corporation for a small business in the North for the first year?ere

It can vary a bit, but a good budget to have in mind for the first year is somewhere in the $1,500 to $3,500 range. That generally covers the legal and accounting fees to get registered and set up properly, plus the cost for your first corporate tax return. After the first year, the annual costs to keep everything filed and up-to-date are much lower.

I do a lot of work on First Nations' land. Does my business structure impact my ability to get contracts or form partnerships with Indigenous development corporations?

It certainly can. An incorporated business is often seen as more stable, permanent, and professional—a huge plus when you’re bidding for contracts with First Nations governments or looking to partner with their economic development corporations. A formal corporate structure gives you the legal foundation you need for joint ventures and other partnerships, which are incredibly common on major Northern projects.

What can I deduct as a self-employed plumber in BC?

Beyond standard tools and materials, many plumbers miss deductions like protective gear (steel-toed boots, safety glasses), specialized software for scheduling, union dues, and even a portion of your vehicle’s maintenance if it’s used for service calls. We help you track every “hidden” deduction to lower your year-end tax bill. To get a personalized list of deductions for your business, contact our Vancouver office today.

Should I incorporate my plumbing business or stay a sole proprietor?

This is a common question for growing trades. Generally, once your plumbing business is netting more than you need for personal living expenses, incorporating can offer significant tax deferral advantages and limited liability protection. We provide a full cost-benefit analysis to help you decide when to make the switch.

How do I manage GST/PST on plumbing materials and labor?

Navigating sales tax in BC can be tricky for trades. You must charge GST on your labor and materials, but you can also claim Input Tax Credits (ITCs) for the GST you pay on business purchases. We streamline your bookkeeping so your quarterly filings are accurate and painless.
