Tax Obligations You Can’t Ignore in Your First Year
GST/HST registration, income tax filing, and deduction tracking. Stay compliant from the start.
Why Your First Year Matters Most
You’ve registered your business. You’re making sales. But here’s what keeps a lot of first-time business owners up at night — the tax stuff. It’s not glamorous, but getting it right from day one saves you headaches later.
The CRA doesn’t care that you’re new. They expect the same compliance from your business as they do from established companies. Miss a deadline or misfile something, and you’re looking at penalties that could’ve been prevented with proper planning.
This guide walks you through the core tax obligations you’ll face in your first year. Not the advanced stuff — just what you actually need to know to stay compliant and avoid expensive mistakes.
GST/HST Registration — When and Why
GST (Goods and Services Tax) or HST (Harmonized Sales Tax, depending on your province) isn’t optional forever. You need to register when your business revenue hits $30,000 in a four-quarter period.
Here’s the thing — you can register voluntarily before you hit that threshold. A lot of new businesses do this because they’re selling to other businesses. When you’re GST-registered, you can claim input tax credits on your business expenses, which means you get back the GST you paid on things like equipment, supplies, and services.
Key deadline: You’ve got 30 days from hitting $30,000 in revenue to register. Don’t wait until the CRA finds out you should’ve done it months ago.
Once you’re registered, you’re filing returns either monthly, quarterly, or annually depending on your revenue level. If you’re doing $1.5 million+ per year, it’s mandatory monthly. Below that, you usually get quarterly or annual options.
Income Tax Filing — Your Annual Deadline
Whether you’re a sole proprietor, partnership, or corporation, you’re filing income tax with the CRA. For sole proprietors and partnerships, you’re reporting business income on your personal tax return. Corporations file separately.
The deadline for most businesses is June 15 the following year. But here’s the catch — if you owe money, you still need to pay by April 30. You get extra time to file, but not to pay. Miss that April 30 payment date and you’re looking at interest charges that add up fast.
You’ll need to track everything throughout the year — revenue from all sources, business expenses, capital purchases, vehicle expenses if it’s business use. This isn’t something you figure out on June 1st. You’re doing this all year.
- Keep receipts for everything — they’re your proof
- Track mileage if you use a vehicle for business
- Record all business use of home office space
- Save bank statements and invoice records
Tracking Deductions From Day One
This is where a lot of new business owners leave money on the table. Deductions reduce your taxable income, which means lower taxes. But you need to be organized from the start.
Common deductions in your first year include office supplies, software subscriptions, professional services, advertising, vehicle expenses, rent or mortgage interest (if you have a home office), utilities for your business space, and equipment purchases. The key is keeping records that prove these are legitimate business expenses.
Startup Costs
Initial equipment, legal fees, and incorporation costs. You can deduct some immediately, others get amortized over time.
Ongoing Operations
Monthly expenses like rent, utilities, insurance, and employee salaries. These are fully deductible in the year you incur them.
Capital Assets
Equipment and property get depreciated over several years through Capital Cost Allowance (CCA). Not a one-time deduction.
Payroll Taxes — If You’re Hiring
The moment you hire your first employee, you’re responsible for payroll taxes. This isn’t optional, and it’s not something you can wing. You’re withholding income tax, Canada Pension Plan contributions, and Employment Insurance premiums from their paychecks and remitting them to the CRA.
You’re also paying employer contributions for CPP and EI. This adds about 5-6% on top of employee wages. Payroll remittances are due monthly or on specific dates depending on your payroll frequency and business size.
Missing payroll remittances is serious. The CRA treats this as a trust account issue, and penalties can be substantial. Plus, you’re personally liable if your business doesn’t pay. So if you’re hiring, set up a proper system from the first payday.
“Setting up payroll correctly from the start is cheaper than fixing it later. We’ve seen businesses hit with penalties that could’ve been avoided with 30 minutes of setup.”

Your First-Year Compliance Checklist
You don’t need to be a tax expert, but you do need to stay on top of these dates and requirements.
Immediately
Register for a business number with the CRA. Get a GST account set up, even if you’re not registering yet. Open a separate business bank account and start tracking expenses from day one.
Ongoing (Monthly)
Review your revenue against the $30,000 GST threshold. Keep all receipts organized. If you’re running payroll, process and remit payments on schedule. Reconcile your bank account.
Quarterly
If you’re GST-registered, file quarterly returns. Review your deductions to make sure you’re not missing anything. Check that payroll remittances have been submitted.
By April 30
If you owe income tax, payment is due. This applies even if you’re still preparing your return. Get ahead of this deadline.
By June 15
File your income tax return. For partnerships and sole proprietors, this is your deadline. Corporations have different dates depending on their fiscal year.
Tools That Make Compliance Easier
You don’t need to do this all manually. There’s software and resources that’ll save you time and reduce the chance of missing something important.
Accounting Software
Tools like Wave, FreshBooks, or Xero automate expense tracking and invoice management. They’re worth setting up early.
Document Organization
Use folders or digital systems to keep receipts organized by category. Future you will thank present you.
Deadline Calendar
Create a calendar with all CRA deadlines. Set reminders a week before each one. Missing dates is the fastest way to penalties.
Accountant Consultation
A consultation in month two or three costs way less than fixing problems later. Get professional eyes on your setup.
The Bottom Line
Tax obligations in your first year aren’t complicated, but they do require attention. GST/HST registration, income tax filing, deduction tracking, and payroll compliance aren’t negotiable. You can’t ignore them and hope for the best.
The good news? Getting it right from the start is actually easier than fixing it later. Set up your systems now, stay organized, and hit those deadlines. You’ll avoid penalties, keep the CRA happy, and honestly, sleep better at night knowing you’re compliant.
