186## Section 4 -- Worked Examples
187 
188### Example 1 -- Standard Sole Proprietor (Web Developer)
189 
190**Input:** Gross revenue CAD 95,000. Not GST registered (under $30K threshold last year, now over -- must register). Expenses: home office (see below), software CAD 2,400, accounting CAD 1,500, subcontractor CAD 8,000, travel CAD 3,000, meals (50%) CAD 1,200 (deductible: CAD 600).
191 
192**Home office:** 1,200 sq ft house, 150 sq ft office (12.5%). Mortgage interest CAD 8,000, property tax CAD 4,000, utilities CAD 3,600, insurance CAD 1,800. Total: CAD 17,400 x 12.5% = CAD 2,175.
193 
194**Computation:**
195- Revenue: CAD 95,000
196- Expenses: 2,400 + 1,500 + 8,000 + 3,000 + 600 + 2,175 = CAD 17,675
197- Net business income: CAD 77,325
198- CPP: (77,325 - 3,500) x 11.9% = CAD 8,068.20 (hits maximum)
199- Half CPP deductible: CAD 4,034.10
200 
201### Example 2 -- Vehicle (Km-Based Apportionment)
202 
203**Input:** Total km driven: 25,000. Business km: 15,000 (60%). Vehicle costs: gas CAD 3,600, insurance CAD 2,400, repairs CAD 800, licence CAD 120. Car cost CAD 36,000 (Class 10).
204 
205**Computation:**
206- Operating costs: (3,600 + 2,400 + 800 + 120) x 60% = CAD 4,152
207- CCA: CAD 36,000 x 30% (Class 10 rate) x 60% = CAD 6,480 (first year: AccII provides 1.5x = CAD 9,720 if eligible)
208- Total vehicle deduction: CAD 4,152 + CCA amount
209 
210### Example 3 -- Meals (50% Rule)
211 
212**Input:** CAD 2,500 in restaurant receipts for client meetings.
213 
214**Classification:** Only 50% deductible = CAD 1,250. This is a permanent restriction under ITA s67.1. The full CAD 2,500 is reported on Line 8523, then 50% is added back.
215 
216### Example 4 -- CCA on Computer Equipment
217 
218**Input:** Laptop purchased for CAD 2,800. Class 50 (55% rate). First year.
219 
220**Classification:** CCA Class 50 at 55%. With AccII (Accelerated Investment Incentive), first-year deduction enhanced: 1.5 x 55% x CAD 2,800 = CAD 2,310 (but cannot exceed cost, so CAD 2,310). UCC year-end: CAD 490.
