Recommended -- marital status, spouse income, dependants, medical expenses, charitable donations.

The transaction pattern library is in the `ca-fed-t2125` skill. This skill consumes the output of that computation (taxable income, net income) and applies BC rates and credits. ## Section 4 -- Worked Examples ### Example 1 -- Low Income, Single Input: Taxable income $25,000. Net income $25,000. Single, no dependants. Computation: - Gross BC tax: $25,000 x 5.06% = $1,265.00 - BC basic personal credit: $12,580 x 5.06% = $636.55 - BC basic tax: $1,265.00 - $636.55 = $628.45 - BC tax reduction: $521 - (3.56% x $25,000) = $521 - $890 = $0 (eliminated) - Net BC tax: $628.45 ### Example 2 -- Mid-Range Income Input: Taxable income $80,000. Single. Computation: - First $47,937 at 5.06% = $2,425.61 - $32,063 at 7.70% = $2,468.85 - Gross BC tax: $4,894.46 - Credit: $636.55 - Net BC tax: $4,257.91 ### Example 3 -- High Income, Top Bracket Input: Taxable income $300,000. Married, spouse income $0. Computation: - Tax through $252,752 = $29,515 - $47,248 at 20.50% = $9,685.84 - Gross BC tax: $39,200.84 - Credits: basic $636.55 + spousal $636.55 = $1,273.10 - Net BC tax: $37,927.74 ### Example 4 -- Below Basic Personal Amount Input: Taxable income $10,000.
