## Section 2 -- Required Inputs and Refusal Catalogue

### Required Inputs

**Minimum viable** -- net self-employment income (from T2125), province of residence on December 31, SIN, date of birth, marital status.

**Recommended** -- other income sources (T4, T5, T3), RRSP deduction, tax instalments paid, prior year NOA.

**Ideal** -- complete T-slip package, full deduction schedule, prior year carryforwards, CPP/EI elections.

### Refusal Catalogue

- **R-CA-T1-1 -- Non-residents** — Non-resident returns have different rules. Out of scope.
- **R-CA-T1-2 -- Deceased / bankruptcy returns** — Require specialist handling. Escalate.
- **R-CA-T1-3 -- Trust income allocation** — Out of scope.
- **R-CA-T1-4 -- Provincial tax computation** — Provincial tax is separate. Use the appropriate provincial skill.

## Section 3 -- Transaction Pattern Library

The T1 skill consumes outputs from the T2125 skill (net business income) and T-slips. Transaction pattern classification is in the `ca-fed-t2125` skill. This skill assembles the return from those inputs.

## Section 4 -- Worked Examples

### Example 1 -- Standard Self-Employed

**Input:** Net business income $85,000. RRSP $10,000. No other income. No EI. Ontario.

**Computation:**
- Total income: $85,000
- CPP: max $8,068.20. CPP2: max $792.00. Total: $8,860.20
- CPP employer-half deduction: $4,430.10
- Net income: $85,000 - $10,000 - $4,430.10 = $70,569.90
- Taxable income: $70,569.90
- Federal tax: $57,375 x 14.5% + $13,194.90 x 20.5% = $8,319.38 + $2,704.95 = $11,024.33
- BPA credit: $16,129 x 14.5% = $2,338.71
- CPP employee-half credit: $4,430.10 x 14.5% = $642.36
- Basic federal tax: $11,024.33 - $2,981.07 = $8,043.26
- Plus CPP payable: $8,860.20
- Total before provincial: $16,903.46

### Example 2 -- Low Income, Below BPA

**Input:** Net business income $14,000. No RRSP.

**Computation:**
- CPP: ($14,000 - $3,500) x 11.9% = $1,249.50
- Net income: $14,000 - $624.75 = $13,375.25
- Federal tax: $13,375.25 x 14.5% = $1,939.41
- Credits exceed tax: federal tax = $0
- CPP payable: $1,249.50

### Example 3 -- High Income, Top Bracket

**Input:** Net business income $300,000. RRSP $32,490 (max).

**Computation:**
- CPP + CPP2: $8,860.20. Employer-half: $4,430.10
- Net income: $300,000 - $32,490 - $4,430.10 = $263,079.90
- Federal tax through brackets: $61,588.75
- BPA: $14,538 (reduced for high income). Credit: $2,108.01
- CPP credit: $642.36
- Basic federal tax: $58,838.38
