If you're a contractor, subcontractor, or trades business owner in Manitoba, GST can quickly become confusing - especially when you're busy managing jobs, suppliers, invoices, and day-to-day operations.
Many contractors start out focused on getting work and getting paid, only to realize later they may need to register for GST, track it properly, or file returns with the CRA.
This guide explains the basic of GST for Manitoba contractors in simple terms.
What is GST?
GST stands for Goods and Services Tax. In Canada, GST is a federal sales tax charged on most goods and services.
The current GST rate is 5%.
If your business is registered for GST, you generally:
Charge GST on your invoices
Collect GST from customers
Remit GST to the CRA
Track GST paid on business expenses
Do Contractors Need to Register for GST?
In many cases, yes.
Generally, you are required to register for GST once your business earns more than $30,000 in taxable revenue over four consecutive calendar quarters.
This applies to:
Contractors
Subcontractors
Self-employed tradespeople
Construction businesses
Renovation companies
Even if you have not reached $30,000 yet, some contractors choose to register voluntarily.
Why Would a Contractor Register Early?
Some contractors register before hitting the threshold because it allows them to claim GST paid on business expenses.
This may include GST paid on:
Materials
Fuel
Tools
Equipment
Work vehicles
Phone bills
Software
Advertising
These are called Input Tax Credits (ITCs).
Common Contractor GST Mistakes
Not Tracking GST Separately
A common issue is mixing GST in with regular income and expenses without tracking it properly.
This can create problems when filing returns and may lead to unexpected tax balances.
Forgetting to Set Money Aside
Some contractors collect GST but accidentally spend it as regular income.
Remember: GST collected is not your money - it eventually needs to be remitted to the CRA.
Missing Receipts
You generally need proper records to support expense claims and Input Tax Credits.
This is one reason many contractors are moving to digital receipt systems like Dext.
Falling Behind on Bookkeeping
When bookkeeping gets delayed for months, GST filings become much harder and more stressful.
Monthly bookkeeping helps keep everything organized and easier to manage.
What Expenses Can Contractors Usually Claim GST On?
Every business is different, but contractors commonly track GST on:
Materials and supplies
Fuel
Vehicle expenses
Tools and equipment
Safety gear
Advertising
Cell phones
Internet
Software subscriptions
Insurance
Professional fees
Good record keeping is important to support these claims.
What About Manitoba PST/RST?
In Manitoba, businesses may also deal with RST (Retail Sales Tax), often called PST.
RST rules for contractors can become complicated depending on:
The type of work performed
Whether materials are supplied
The type of customer
The nature of the project
Because construction and trades work can involve both GST and RST considerations, organized bookkeeping becomes even more important.
Why Contractors Benefit From Monthly Bookkeeping
Monthly bookkeeping helps contractors:
Stay organized
Track cash flow
Prepare for GST filings
Monitor profitability
Keep records CRA-ready
Avoid year-end stress
It also gives you a clearer picture of how your business is actually performing.
Many contractors are surprised to learn how much money leaks through untracked expenses, underpriced jobs, or inconsistent record keeping.

Avoid surprises
