Frequently asked questions
Can a plumber deduct pipe cutters and other tools? ▼
Yes. The tradesperson tools deduction allows you to deduct new tool costs above a $1,369 threshold (2025), up to $500, with a T2200 from your employer. Self-employed plumbers can deduct all necessary tools as business expenses on T2125.
Do self-employed plumbers pay more tax? ▼
Self-employed plumbers pay both the employee and employer CPP contributions (doubling the rate), but they can deduct all legitimate business expenses, which employees generally cannot. Net self-employment income is taxed at the same marginal rates as employment income.
Should a plumbing contractor incorporate? ▼
If annual net business income is consistently above $75,000–$100,000, incorporation can provide tax deferral benefits via the small business deduction. Speak with a CPA to weigh the costs of incorporation against the tax savings.
Are union dues deductible for plumbers? ▼
Yes. Dues paid to UA Local unions or other provincial plumbing trade unions are deductible on line 21200 of your T1 return.
