Part-time as the sole income source
A part-time role uses the same guaranteed-vs-variable framework as Module 02's hourly income — the difference is mainly that part-time roles more often lack a guaranteed floor, which pushes more files toward averaging rather than a straightforward salary-style treatment.
Multiple concurrent jobs
Each employer needs its own documentation — its own letter, its own recent pay stub, its own T4/NOA history — and the two (or more) incomes are only combined once each is independently supported. A track record of holding both jobs concurrently for a reasonable period, ideally visible on a Notice of Assessment showing multiple T4 slips in the same year, is what makes combining them credible rather than speculative.
A second job as 'extra' income vs core income
A second job held for only a few months is treated more cautiously than a first job — it's new, unproven, and easy to lose. Two years of concurrent history across both roles is a materially stronger file than a first or second job that just started, for the same tenure reasons that run through every module in this course.
Practical assembly
Don't assume T4 totals from a single tax year can simply be added together if the borrower changed jobs partway through — a full T1/NOA breakdown by income source is worth requesting whenever more than one T4 shows up in a single year, so the actual source of each dollar is clear before it's combined.
When a 'job' is actually self-employment
A side gig sitting alongside a full-time T4 job is common, but if that side income is genuinely self-employment — no T4, reported via a T2125 — it needs the treatment in Course 03, not the T4-based approach in this module. Confirm which slip, if any, is actually issued before assuming it belongs here.
