Pension splitting checks.
Use these checks before treating the tax software result as the whole planning answer.
| Decision | What to check first |
|---|---|
| Eligible income | Defined benefit pension, RRIF/LIF income by age, and income that cannot be split. |
| Spouse income gap | Whether shifting eligible income improves the household result after credits and benefits. |
| Credits and OAS exposure | Age amount, pension amount, medical credits, OAS recovery tax, and net-income-tested items. |
| Software vs planning result | Whether the filed election still fits the year-ahead withdrawal and income plan. |
Pension income splitting can help some couples, but it should be reviewed beside credits, OAS recovery tax, RRIF income, age, and the type of pension income involved.
Key takeaways
- CRA rules define which income is eligible.
- OAS and CPP are not eligible pension income for splitting.
- The election can affect credits and programs based on one person’s net income.
- Tax software output still deserves a planning review when income is changing.
Who this applies to
Use this when pension income splitting, spouse income levels, credits, OAS recovery tax, RRIF/LIF income, or year-end tax planning could change the household tax result.
If the matter is urgent, legal, tax-filing specific, investment-trade specific, or account-instruction specific, start with the right professional or institution instead of relying on a public article.
The planning issue
- CRA rules define which income is eligible.
- OAS and CPP are not eligible pension income for splitting.
- The election can affect credits and programs based on one person’s net income.
- Tax software output still deserves a planning review when income is changing.
A pension-splitting review should show whether the election improves the household result after credits, OAS exposure, benefit-tested items, and the year-ahead income plan are considered.
Example Ontario scenario
One spouse has a defined benefit pension and the other has lower taxable income. Splitting may help, but the household also needs to check OAS recovery tax and credits that depend on individual net income.
The first planning conversation would compare eligible income, spouse income gap, credits, OAS exposure, and the year-ahead income plan before treating the software result as final.
Documents to gather
- Latest tax return and notice of assessment for both spouses
- Pension slips, pension statements, and the type of pension income involved
- RRIF/LIF income details and each spouse’s age
- Credits, benefit-tested items, and OAS recovery-tax exposure that may change with individual net income
- Prior-year tax software result or preparer notes if available
Keep sensitive documents out of public notes and ordinary email until the office confirms the secure route.
Red flags to slow down for
- Assuming tax software optimization is the same as planning
- Ignoring OAS recovery tax or credits affected by individual net income
- Missing the age, RRIF, LIF, or eligible-income rules
- Treating CPP or OAS as eligible pension income for splitting
- Reviewing one tax year without checking the year-ahead income plan
Questions that change the next step
- What decision is actually being made, and what can wait?
- Which facts would change the answer?
- What costs, taxes, fees, or paperwork could appear if action is taken now?
- Who else needs to be involved before anything permanent changes?
- What would a clean next step look like after the first conversation?
Professional boundaries to keep clear
- Financial advisor or planner
- Accountant or tax preparer
- Lawyer for estate documents
- Current pension or account institution
- Insurance professional when coverage is part of the question
