Why Corporate Tax Planning Matters for Windsor Businesses
| Without Tax Planning | With Gondaliya CPA Tax Planning |

| Paying up to 26.5% corporate tax on all income | SBD applied: 12.2% on the first $500,000 of active business income |

Corporate Tax Planning Services for Windsor Businesses
| Service | What We Do for Windsor Businesses |
|---|---|
| SBD optimization | The Small Business Deduction reduces your corporate tax rate to 12.2% on the first $500,000 of active business income. We ensure every eligible dollar qualifies. Associated corporation analysis completed for Windsor multi-corp owners including tool shop plus property holding structures common in Essex County. |
| Salary-dividend optimization | We calculate the ideal salary-dividend split based on your personal tax bracket, RRSP contribution room, CPP benefit goals and family situation. Most Windsor business owners save $8,000 to $25,000/year from the correct split alone. |
| Holdco structuring | Once retained earnings exceed $200,000, we establish a holding company. Investments transfer from the operating company to the holdco via tax-free inter-company dividends. Passive income is isolated from the SBD calculation. Wealth is protected from operating business risk and product liability claims common in the automotive supply chain. |
| SR&ED tax credits | Windsor has one of Canada's highest concentrations of tool and die, mould making and precision machining. Designing new moulds, developing injection parameters for new polymers, prototyping automotive components, testing new alloys and programming multi-axis CNC for complex geometries all qualify. We prepare the T661: 35% refundable credit on eligible expenditures. |
| Cross-border tax planning | Windsor businesses selling to US customers, importing US raw materials or employing US-resident workers face cross-border tax issues. We structure US sales as zero-rated exports (HST refund), file W-8BEN-E for treaty benefits, manage transfer pricing between Canadian parent and US subsidiary and ensure compliance with both CRA and IRS requirements. |
| Immediate Expensing | CCPCs can deduct up to $1.5 million in eligible property purchases in the year of acquisition. A Windsor mould maker buying a $600,000 5-axis CNC machining centre gets a $600,000 deduction in year one instead of 20% declining balance over many years. |
| LCGE planning | Each shareholder of a qualifying CCPC can shelter up to $1,281,866 in capital gains on exit. We issue non-voting shares to family members, maintain the 24-month holding period and monitor the 90% active asset test. Two owners with spouses: $5.1 million sheltered. Critical for Windsor tool shop owners planning succession. |
| CRA audit support (FREE) | If CRA reviews or audits your corporate tax return, we represent you at no additional charge. We respond to every CRA request, attend every meeting and negotiate every reassessment. CRA audit support is FREE for every Gondaliya CPA client. Corporate Tax Planning → |
Windsor Corporate Tax Planning: Real Client Results
Tool and Die Shop, Oldcastle
A Windsor-area tool and die shop designing and manufacturing injection moulds for Tier 1 automotive suppliers had $920,000 in income and was paying 26.5% on everything above the SBD. We applied the SBD to the first $500,000 (12.2%), claimed the Ontario M&P rate on the $420,000 above the SBD (25.0% instead of 26.5%), filed a first-ever SR&ED claim on mould design, injection parameter development and multi-axis CNC programming ($78,000 refundable credit) and claimed Immediate Expensing on a $540,000 5-axis machining centre. Annual tax savings: $84,600.
Cross-Border Trucking Company, Windsor
A Windsor trucking company with 12 trucks crossing the Ambassador Bridge daily had $1.6 million in revenue. 70% of revenue was from US-origin freight. We structured the cross-border operations correctly: zero-rated HST on US freight (producing $8,400/quarter in HST refunds), filed W-8BEN-E for US withholding treaty benefits, claimed Immediate Expensing on 4 new trucks ($480,000 total), established a holdco for $380,000 in retained earnings and managed IFTA fuel tax compliance. Annual savings: $46,200 in corporate tax plus $33,600 in annual HST refunds.
Greenhouse Grower, Leamington
A greenhouse operation in Leamington growing tomatoes and peppers for national grocery distribution had $780,000 in revenue. We incorporated the farming operation (farming income qualifies for SBD), applied the $1 million Lifetime Capital Gains Exemption on qualified farm property in addition to the standard $1,281,866 CCPC LCGE, claimed Immediate Expensing on $320,000 in greenhouse equipment (automated irrigation, climate control systems), established a holdco for $260,000 in retained earnings and claimed SR&ED on controlled environment agriculture research ($34,000 credit). Annual savings: $38,400.
Healthcare Professional, Windsor Regional Hospital Area
A specialist physician in Windsor earning $460,000 through a professional corporation had no holdco and $54,000 in passive investment income eroding the SBD. We implemented a 55/45 salary-dividend split ($30,800 RRSP room created), established a holdco, transferred $480,000 in investments via tax-free dividends and restored the full SBD. We also set up an IPP for $36,000 in additional annual contributions. Annual savings: $37,600.

10 Advanced Corporate Tax Strategies for Windsor Businesses
1. Maximize the SBD by managing passive income
Passive investment income above $50,000 inside the operating corporation erodes the SBD. Every $1 above $50,000 reduces the SBD limit by $5. At $150,000 in passive income, the SBD is eliminated entirely, costing $71,500 in additional tax. We transfer investments to a holdco before this threshold is reached.
2. Claim the manufacturing and processing rate
Windsor tool and die shops, mould makers and manufacturers qualify for a reduced Ontario rate of 10.0% (vs. 11.5%) on eligible M&P income above the SBD threshold. This reduces the combined rate from 26.5% to 25.0%. On $400,000 above the SBD, the savings are $6,000/year. We calculate M&P eligibility for every manufacturing client in Windsor and Essex County.
3. File SR&ED for tooling and mould development
Windsor tool and die shops designing custom moulds, developing injection parameters for new materials, prototyping components, testing tool steels and programming multi-axis CNC for non-standard geometries qualify for SR&ED. The 35% refundable credit on $250,000 in eligible expenditures produces $87,500 in cash from CRA. We prepare the T661 including the technical narrative and financial summary.
4. Structure cross-border operations for tax efficiency
Windsor businesses with US customers should zero-rate HST on all exports (producing quarterly refunds), file W-8BEN-E for 0% treaty withholding, structure transfer pricing between Canadian parent and US subsidiary and manage US state-level tax obligations. A Windsor mould shop with $600,000 in US sales that incorrectly charges 13% HST overpays CRA by $78,000/year.
5. Use Immediate Expensing on CNC and tooling equipment
A $600,000 5-axis CNC machining centre, a $300,000 injection moulding press, a $200,000 fleet upgrade or $180,000 in shop renovations can be fully deducted in the year of purchase under Immediate Expensing (CCPC, up to $1.5 million). This accelerates the deduction from 20% declining balance to 100% in year one.
6. Implement salary-dividend optimization annually
The optimal salary-dividend split changes every year based on personal income, RRSP room, CPP contribution status and family changes. We recalculate annually. A shift from 100% dividends to a 60/40 salary-dividend split typically creates $28,000 to $55,000 in new RRSP contribution room.
7. Establish a holdco with creditor protection
Windsor manufacturers face product liability risk from the automotive supply chain. A holdco separates accumulated wealth from the operating entity. If a defective part triggers a warranty claim or lawsuit, the holdco assets are protected. We establish the holdco, handle the share subscription and manage the annual inter-company dividends.
8. Issue family shares for LCGE multiplication
Non-voting shares issued to a spouse and adult children allow each shareholder to claim their own LCGE on exit ($1,281,866 each). Two founders with two spouses: $5.1 million sheltered from capital gains tax. Critical for Windsor tool shop owners planning to sell or transition to the next generation.
9. Leverage the farm property LCGE for greenhouse operations
Windsor and Leamington greenhouse operators qualify for the $1 million Lifetime Capital Gains Exemption on qualified farm property in addition to the standard $1,281,866 CCPC LCGE. With proper structuring, a family greenhouse operation can shelter over $4.5 million in capital gains on sale using both exemptions across multiple family shareholders.
10. Plan for succession and exit from day one
Whether you are selling your Windsor tool shop in 5 years or transitioning it to the next generation in 20, the exit structure must be in place now. LCGE eligibility requires a 24-month holding period, 90% active asset test and qualifying CCPC shares. Estate freeze, family trust and intergenerational transfer structures all require advance planning. For Windsor family-owned manufacturers, the intergenerational transfer rules offer additional tax-deferred options. We build the exit plan into your tax strategy from the first year.
