Section 2 -- Required Inputs and Refusal Catalogue

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
