Why your commuted value gets split
When you elect to take the commuted value of your defined benefit pension, you might expect the full amount to transfer into a Locked-In Retirement Account (LIRA) on a tax-sheltered basis. In reality, only a portion does. The rest is paid out to you as taxable cash.
This split is governed by Income Tax Act Section 8517, which sets the maximum amount that can be transferred from a registered pension plan to a LIRA without triggering immediate taxation. The limit exists because the government wants to ensure that tax-sheltered retirement savings are tied to a reasonable estimate of the pension benefit being replaced — not used as a vehicle for unlimited tax deferral.
How the ITA §8517 limit is calculated
The transfer limit is calculated by multiplying your annual accrued pension by a prescribed factor from the Income Tax Regulations. The factor increases with age — recognizing that older workers have fewer years for the lump sum to compound before retirement.
The formula is:
LIRA Transfer Limit = Annual Accrued Pension × Prescribed Factor (based on age)
The prescribed factors range from approximately 9.0 at age 30 to over 13.0 at age 60. The exact factor for your age is set by the federal regulations and is the same regardless of which province you're in.
What the split looks like in practice
A practical example
Suppose a member aged 45 has an accrued annual pension of $28,000 and receives a commuted value of $520,000.
At age 45, the prescribed factor is approximately 11.0.
LIRA transfer limit = $28,000 × 11.0 = $308,000
The remaining $212,000 is paid as taxable cash — added to income in the year of termination. At a marginal tax rate of 46%, this could result in a tax bill of nearly $97,000 on that portion alone.
This is why understanding the split before you elect is essential to financial planning.
The taxable cash portion cannot be contributed to an RRSP to defer the tax — it is specifically excluded from RRSP contribution room by the pension adjustment rules. What you can do is use any existing RRSP room you may have from prior years to offset some of the tax impact. Speak to a tax advisor before your termination date.
What happens to the LIRA?
A Locked-In Retirement Account works similarly to an RRSP in that it grows tax-sheltered — but with important restrictions:
- Locked in — you generally cannot withdraw funds as a lump sum before retirement (subject to limited hardship exceptions that vary by province)
- Investment flexibility — you can invest the LIRA in GICs, mutual funds, ETFs, or other eligible investments at the financial institution of your choice
- Conversion at retirement — at retirement (typically between age 55 and 71), the LIRA must be converted to a Life Income Fund (LIF), which provides a regulated annual income with minimum and maximum withdrawal limits
- Estate transfer — unlike a pension, LIRA and LIF assets can be passed to a spouse or estate on death
Does age affect how much goes into the LIRA?
Yes — significantly. Because the prescribed factor increases with age, older workers typically have a higher proportion of their commuted value eligible for tax-sheltered LIRA transfer relative to their pension amount. However, older workers also tend to have larger pensions, which can result in larger absolute taxable cash amounts.
Younger workers often find that the gap between their commuted value and the transfer limit is larger in percentage terms — a reflection of the long compounding period ahead and the relatively low prescribed factor at younger ages.
Can I reduce the taxable cash amount?
The transfer limit is a fixed calculation — it cannot be negotiated or changed. However, there are a few strategies worth discussing with a tax advisor:
- Use existing RRSP room — if you have unused RRSP contribution room from prior years, you can contribute the taxable cash amount to your RRSP and deduct it against the income, partially or fully sheltering the tax
- Spousal RRSP — contributing to a spousal RRSP using existing room can split the income in retirement
- Timing the termination year — if you expect lower income in a particular year (a sabbatical, reduced hours, or early in the year), terminating in that year can reduce your marginal rate on the taxable cash
How CVCalculator handles the split
CVCalculator calculates your ITA §8517 transfer limit automatically as part of every calculation. You'll see your estimated LIRA transfer amount and taxable cash amount alongside your commuted value — so you understand the full financial picture before you make any decision.
This is one of the most practically useful outputs of the calculator, because it's the number that determines your actual after-tax proceeds from taking the commuted value.
