We Incorporate Oshawa Businesses the Right Way from Day One
We incorporate businesses in Oshawa every week: skilled trades operators and contractors in North Oshawa, automotive parts suppliers near the GM Oshawa Assembly plant, medical clinics near Lakeridge Health, dental practices in Downtown Oshawa, restaurant operators along King Street and Simcoe Street, real estate investors across Durham Region, construction companies in Taunton and Windfields, retail businesses in the Oshawa Centre area, IT consultants in Samac and professional services firms throughout Oshawa. Every incorporation includes a multi-class share structure, complete minute book, CRA registrations and a tax planning conversation that sets the foundation for paying the lowest possible tax from your first dollar of revenue.
The most common mistake Oshawa business owners make is incorporating after they have already started earning income. A trades operator who incorporates 2 years late at $150,000/year in income has already paid $48,000 more in tax than they would have as a corporation. We incorporate you before you earn the first dollar so every dollar flows through the corporation at 12.2% instead of up to 53.53% personal. Our service fee is just $35.

10 Smart Incorporation Strategies That Can Save Oshawa Business Owners Money
1. Incorporate before earning your first dollar to lock in 12.2%
Every dollar earned as a sole proprietor is taxed at your personal rate (up to 53.53% in Ontario). Every dollar inside a corporation is taxed at 12.2% under the SBD. An Oshawa electrician earning $185,000 saves $31,200 in the first year by incorporating before the first job. Our service fee is $35.
2. Issue non-voting shares to your spouse at incorporation to multiply the LCGE
The Lifetime Capital Gains Exemption shelters $1,281,866 per shareholder. Issuing non-voting shares to your spouse at incorporation doubles the exemption to $2,563,732. This costs nothing at incorporation but saves hundreds of thousands on a future business sale.
3. Use a salary-dividend split from your first pay period to create RRSP room
Most Oshawa business owners default to 100% dividends. But dividends create zero RRSP room. A 60/40 salary-dividend split on $200,000 creates $72,000 in cumulative RRSP room while keeping the combined tax lower than either salary-only or dividend-only.
4. Register for HST at incorporation and claim ITCs on every expense
Oshawa construction companies must charge HST from day one. Registering at incorporation allows you to claim ITCs on all startup expenses including tools, vehicles, equipment and materials. A trades operator spending $30,000 on tools and a vehicle recovers $3,900 in ITCs.
5. Claim Immediate Expensing on equipment purchased through the corporation
An Oshawa automotive parts manufacturer buying $124,000 in CNC equipment or a contractor buying $45,000 in tools and a work vehicle gets the full amount as a year-one deduction under Immediate Expensing. Incorporate before the purchase.
6. Use a section 85 rollover to convert from sole proprietorship tax-free
An Oshawa automotive supplier with $86,000 in equipment and inventory who incorporates without a section 85 rollover pays approximately $12,400 in unnecessary tax. The rollover transfers everything to the new corporation at tax cost, deferring the gain entirely.
7. Plan for the holdco from incorporation so passive income never erodes the SBD
Passive investment income above $50,000 erodes the SBD, costing up to $71,500/year. We discuss the holdco timeline at incorporation and trigger the setup when retained earnings reach $200,000. Oshawa construction companies with strong cash flow often reach this within 18 to 24 months.
8. File T5018 on time to avoid CRA penalties and audit triggers
Oshawa construction companies must file T5018 slips reporting subcontractor payments of $500+. Missing T5018s trigger $25/day penalties per slip and a CRA audit of the entire subcontractor payment structure. We file T5018 for every construction client.
9. Structure worker classification correctly from day one
CRA targets Oshawa construction and trades businesses for worker misclassification. Classifying employees as contractors to avoid CPP, EI and payroll triggers reclassification, back-assessed CPP/EI for all years, penalties and potential prosecution. We review every worker relationship at incorporation.
10. Bundle incorporation with bookkeeping and get the service fee waived entirely
Oshawa business owners who sign up for monthly bookkeeping ($100/month) receive incorporation at no service charge (government filing fee only). The bookkeeping includes bank reconciliation, HST filing, monthly financials and the T2 filed FREE every year. Incorporation Services →
