## Section 2 -- Required Inputs and Refusal Catalogue

### Required Inputs

Recommended -- marital status, spouse income, dependants, medical expenses, charitable donations. Ideal -- complete T1 data, prior year BC428, disability certificate if applicable.

## Section 3 -- Transaction Pattern Library

BC provincial tax is computed from federal return data, not directly from bank transactions. 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
