Accounting for Plumbers: Is it Time to Incorporate?

As a Canadian small business owner running a corporation, I’ll bet you’ve heard the magic number: 9%. That’s the federal small business tax rate, and man, does it look good on paper. It’s so easy to fixate on that one number and think you’ve already won the tax game. But have you really?

Here’s the part that trips up so many entrepreneurs. Your business is one wallet, and you are another. That 9% is just the tax paid inside the company. The real game—and your biggest chance to save serious cash—is figuring out how to move money from the business wallet to your personal one. Focusing only on the corporate rate is like watching only the first period of a hockey game; you’re missing how it all plays out.

This is where a little thing called “tax integration” comes in. The CRA set up the system so that, ideally, a dollar earned in your corporation and paid out to you gets taxed at roughly the same rate as if you just earned it personally. But here’s the kicker: it’s almost never a perfect match. That little bit of wiggle room is exactly where smart CCPC tax planning can save you a bundle.

Salary vs. Dividends: The Great Debate

So, how should you pay yourself? It’s the most fundamental question in any Canadian small business tax strategy. You’ve got two main options, salary and dividends, and they are worlds apart.

The Case for a Salary

Think of a salary as the tried-and-true, traditional route. Your corporation pays you, just like any other employee.

The Upside:

  • RRSP Room: This is huge. A salary is what generates that precious RRSP contribution room, letting you save for retirement with tax-deferred dollars. Dividends give you zero.
  • CPP Contributions: You’ll be paying into the Canada Pension Plan, building up your government pension for when you retire. It’s like a forced savings plan, which isn’t always a bad thing.
  • Corporate Deduction: Your salary is a business expense. Plain and simple. It directly lowers your corporation’s taxable income, which is an amazing tool for managing your final tax bill.
  • Other Perks: An income history from a salary makes it way easier to get a mortgage. Plus, it lets you set up a Health Spending Account (HSA) to pay for medical bills using pre-tax corporate money.

The Downside: It’s not all perfect. A salary means you’re running payroll. You’re responsible for sending the CRA regular payments for income tax, CPP, and maybe EI. It’s more paperwork, and you feel the personal tax hit right away.

The Case for Dividends

Dividends are different. They’re a slice of the company’s after-tax profits that get paid out to you, the shareholder.

The Upside:

  • Simplicity: No payroll remittances. No monthly source deductions. The admin work is a breeze by comparison.
  • Flexibility & Deferral: You can let profits pile up in the company (where they’re only taxed at that low corporate rate) and only pay yourself a dividend when you actually need the cash. This is a powerful way to defer taxes.
  • No CPP/EI: You don’t pay into CPP or EI on dividends. That means more cash in your pocket today.

The Downside: You don’t build any new RRSP room. And because dividends aren’t a business expense, the company has to pay tax on its profits before it can pay you. When you file your personal return, you get a dividend tax credit to make up for the tax the company already paid. This is tax integration Canada in action, but like we said, it’s rarely a perfect one-for-one offset.

Finding Your Strategic Mix: It’s Personal

So, what’s the verdict? Salary or dividends? The honest answer is almost always: it depends. The best corporate personal tax optimization isn’t about picking a winner; it’s about crafting a custom blend that fits your life and your goals.

Think about it for a second. What do you actually need to live on? Are you laser-focused on maxing out your RRSP every year? Does your business need to hold onto cash so it can grow? Do you have other income, maybe from a spouse or a rental property? And how far away is retirement for you? The answers change everything.

For instance, a younger owner who wants to save aggressively for retirement and needs to qualify for a big mortgage might lean heavily on salary. But an owner who doesn’t need much personal cash right now and hates paperwork? They might be all about dividends.

The Year-End Bonus: A Powerful Timing Tool

Want to hear a fantastic strategy that gives you the best of both worlds? The year-end bonus. Before your corporation’s year-end (let’s say it’s December 31st), it can declare a bonus for you on the books. Bam! That bonus becomes a deductible expense for the corporation in that fiscal year, dropping its tax bill immediately.

But here’s the slick part: you don’t actually have to take the cash until the new year (you have up to 180 days). This means you report that bonus on your personal tax return in the following year. It’s a completely legal way to get a corporate tax deduction now while pushing your personal tax hit down the road. This is a core tactic for small business deduction planning.

The Next Level: The Holding Company

For businesses that are really humming and making more profit than the owner needs to live on, there’s an even more powerful play: the holding company. Instead of paying all that extra profit out to yourself (and triggering a big personal tax bill), you can flow it as a tax-free dividend to a separate holding company you own.

Inside that holding company, you can invest the funds in stocks, real estate, you name it. This structure lets your wealth compound in a much friendlier tax environment, deferring a ton of personal tax until you actually need the money, maybe years from now.

Your Two Wallets Are Connected

Trying to manage your corporate taxes without even thinking about your personal tax situation is a surefire way to leave money on the table. They are two sides of the same coin. Getting them to work together in harmony is the absolute key to building real wealth and being truly efficient with your money.

Your specific life—your income needs, your retirement dreams, your business plans—is what dictates the right strategy. This isn’t something you should be guessing at. This is where professional advice isn’t just helpful; it’s essential. To see how these strategies could work for your business, it’s time to talk to a pro. You can book a comprehensive tax strategy session with our experts to design a plan that keeps more money in your pocket—both now and for the future.

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.
