Pension income splitting calculator.
You can allocate up to 50% of eligible pension income to your spouse or common-law partner on Form T1032. See the split that actually minimizes your combined household tax.
You may allocate up to 50% of eligible pension income to a spouse or common-law partner, via a joint election on Form T1032 — one election per year, same figures on both returns. The best split isn't always the full 50%: this tool scans every allocation from 0–50% and finds the one that produces the lowest combined federal + provincial tax for the two of you together.

How the optimizer works
Combined household tax isn't linear in the split percentage — it bends every time either spouse crosses a tax bracket. This tool checks every allocation from 0% to 50% in 1% steps, computes each spouse's federal + provincial tax at that split using the site's own 2026 tax engine, and reports whichever step produces the lowest combined total. If the two of you are already taxed at similar marginal rates, the answer is often 0% — splitting doesn't always help, and this tool tells you honestly when it doesn't.
What this is not
This is not the same thing as CPP pension sharing with Service Canada — a separate program that lets spouses share their actual CPP retirement pensions. Pension income splitting (Form T1032) is a tax-return election covering RRIF, employer pension and annuity income; OAS and CPP/QPP can never be split through it, at either spouse's age.

Frequently asked questions
Is splitting always worth doing at the full 50%?
No. If both spouses are already in similar tax brackets, shifting income between you can make little or no difference — and past a certain point it can even push the receiving spouse into a higher bracket than it saves the other. That's exactly why this tool scans the whole range instead of assuming 50% is always best.
Does splitting affect OAS clawback?
It can. Moving pension income to a lower-income spouse can reduce the transferring spouse's net income enough to avoid or shrink their OAS recovery tax — but it can also push the receiving spouse's income up. This tool doesn't model the recovery tax; use the CPP & OAS calculator for that side of the picture.
Can I change the split after filing?
You can amend a filed return, but the CRA requires the same figures on both spouses' returns, and only one joint election can be made per tax year.
Can CPP or OAS be part of the split?
No, never, at either spouse's age — OAS and CPP/QPP are excluded from eligible pension income entirely. Only actual CPP pension sharing (a different Service Canada program) can move CPP income between spouses.
Estimate only
This tool optimizes combined federal + provincial income tax only, using the site's 2026 tax tables. It does not model the pension income amount credit, the age amount or its clawback, the OAS recovery tax, provincial health premiums/surtaxes beyond what the tax engine already includes, or any other credit interactions. Confirm your actual figures and eligibility with the CRA or a tax professional before filing Form T1032.
