Canadian tax slip box numbers and form lines (2025)

The CRA box and line numbers KeyGlance reads, with the official label beside each — harvested from the tax software's own templates rather than typed from memory, and written up with what actually goes wrong reading each one.

14 forms · 110 entries

• T4A(P) — CPP/QPP benefits10 boxes · CPP and QPP benefits.
• T4A — Pension and other6 boxes · Pension, retirement, annuity and other income — the slip issuers use for payments that fit nowhere else, including self-employed commissions, fees for services and research grants.
• T4A(OAS) — Old Age Security5 boxes · Old Age Security.
• T5 — Investment income5 boxes · Investment income — dividends, interest and foreign income from a bank or broker.
• T4E — EI benefits4 boxes · Employment Insurance and other benefits, issued by Service Canada.

• T5008 — Securities4 boxes · Securities transactions.
• T4RIF — RRIF income3 boxes · Income out of a RRIF.
• T2202 — Tuition3 boxes · Tuition and enrolment certificate, issued by the institution rather than the student — which is why it is so often missing from a dropoff and downloaded from a student portal later.
• T5007 — Benefits2 boxes · Benefits — workers' compensation and social assistance payments.

Why this list is ours to publish

The numbers are the CRA’s and are printed on the paperwork in your client’s hand. What is unusual is that they have been collected from the tax software’s own exported templates for a specific tax year, rather than transcribed from a paper form that may be a season out of date — which is why boxes like the T4’s 16A and 17A, the second CPP and QPP contributions, are here at all.

What is deliberately not here is the mapping from these boxes to the field codes the tax software addresses them by. That took a month to harvest, nobody searches for it, and it is not ours to republish.
