Section 2 -- Required Inputs and Refusal Catalogue

Required Inputs

• Required Inputs — Minimum viable -- province of residence on December 31 (must be BC), federal taxable income (T1 line 26000), federal net income (T1 line 23600). Recommended -- marital status, spouse income, dependants, medical expenses, charitable donations. Ideal -- complete T1 data, prior year BC428, disability certificate if applicable.

Refusal Catalogue

• R-BC-1 -- Not BC resident — Province of residence on December 31 is not BC. This skill does not apply.
• R-BC-2 -- Corporations/trusts — This skill covers individual sole proprietors only.
• R-BC-3 -- Part-year resident — Part-year provincial residency requires specialist analysis. Escalate.
• R-BC-4 -- First Nations exemption — Section 87 Indian Act exemptions require specialist analysis. Escalate.

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

Example 4 -- Below Basic Personal Amount

Input: Taxable income $10,000.

Computation:

• Gross BC tax: $506.00
• Credit: $636.55
