101## Section 4 -- Worked Examples
102 
103### Example 1 -- Low Income, Single
104 
105**Input:** Taxable income $25,000. Net income $25,000. Single, no dependants.
106 
107**Computation:**
108- Gross BC tax: $25,000 x 5.06% = $1,265.00
109- BC basic personal credit: $12,580 x 5.06% = $636.55
110- BC basic tax: $1,265.00 - $636.55 = $628.45
111- BC tax reduction: $521 - (3.56% x $25,000) = $521 - $890 = $0 (eliminated)
112- Net BC tax: $628.45
113 
114### Example 2 -- Mid-Range Income
115 
116**Input:** Taxable income $80,000. Single.
117 
118**Computation:**
119- First $47,937 at 5.06% = $2,425.61
120- $32,063 at 7.70% = $2,468.85
121- Gross BC tax: $4,894.46
122- Credit: $636.55
123- Net BC tax: $4,257.91
124 
125### Example 3 -- High Income, Top Bracket
126 
127**Input:** Taxable income $300,000. Married, spouse income $0.
128 
129**Computation:**
130- Tax through $252,752 = $29,515
131- $47,248 at 20.50% = $9,685.84
132- Gross BC tax: $39,200.84
133- Credits: basic $636.55 + spousal $636.55 = $1,273.10
134- Net BC tax: $37,927.74
135 
136### Example 4 -- Below Basic Personal Amount
137 
138**Input:** Taxable income $10,000.
