Defined Benefit Pension Tax Guide

10 min readUpdated December 2024

Guaranteed Retirement Income

Defined benefit pensions provide guaranteed income for life. They're fully taxable but qualify for valuable credits like pension income splitting at any age—a significant tax advantage.

How DB Pensions Work

The Formula

  • Years of service × benefit rate × final salary
  • Example: 30 years × 2% × $80,000 = $48,000/year
  • Paid monthly for life
  • Often indexed to inflation (partially or fully)

Employer vs Employee Contributions

  • Both contribute during working years
  • Your contributions tracked separately
  • Employer funds the guarantee

Tax Treatment of DB Pensions

Pension Payments

  • 100% of pension is taxable
  • Reported on T4A slip
  • Tax withheld at source
  • Added to other income

Pension Adjustment (PA)

  • Reduces your RRSP room
  • Reported on T4 while working
  • Reflects pension benefit accrued
  • 9 × benefit earned that year

Pension Income Tax Credits

Pension Income Amount

  • Up to $2,000 credit (federal)
  • DB pension qualifies at any age
  • Don't need to be 65+
  • Worth ~$300 federal tax reduction
  • Plus provincial credit

Pension Income Splitting

  • Split up to 50% with spouse
  • DB pension eligible at any age
  • Unlike RRIF (requires 65+)
  • Significant advantage for DB recipients

Key Advantage: DB pension recipients can split income starting at age 55 (or whenever pension starts). RRIF income can only be split at 65+.

Bridge Benefits

What Is a Bridge?

  • Extra payment until age 65
  • Designed to replace CPP/OAS until they start
  • Reduces after 65
  • 100% taxable

Example

  • Retire at 60
  • Pension: $40,000/year + $12,000 bridge
  • Total until 65: $52,000
  • After 65: $40,000 + CPP + OAS

Commuted Value Option

What Is Commuted Value?

  • Lump sum equivalent of future pension
  • Can be offered at retirement
  • Or when leaving employer before retirement

Tax Implications

  • Part transfers to LIRA (tax-free)
  • Excess is taxable immediately
  • Maximum transfer limit applies
  • Can be significant tax hit

Transfer Limit

Maximum that can go to LIRA depends on:

  • Your age at transfer
  • Prescribed formula
  • Excess taxable as income
  • Often 50-70% transfers, rest taxable

Commuted Value Decision: Taking the lump sum forfeits guaranteed income and may trigger large tax. Most people are better off keeping the pension unless specific circumstances apply.

Early Retirement Reduction

How Reduction Works

  • Retiring before "unreduced" age
  • Typically 3-6% per year early
  • Reduction is permanent
  • May still be worthwhile

Example

  • Unreduced pension at 65: $50,000
  • 5% reduction per year before 65
  • Retire at 60: 25% reduction
  • Pension: $37,500/year for life

Survivor Benefits

Typical Options

  • 60% survivor pension (most common)
  • 100% survivor pension (lower initial)
  • No survivor (higher initial, nothing to spouse)

Tax Implications

  • Survivor pension taxable to survivor
  • Qualifies for pension income credits
  • Can be split if survivor remarries

DB Pension vs Commuted Value Analysis

Keep the Pension If:

  • Expect long life
  • Value guaranteed income
  • Poor at managing investments
  • Pension is indexed
  • Good survivor benefits

Consider Commuted Value If:

  • Serious health concerns
  • No dependants needing survivor pension
  • Sophisticated investor
  • Pension not indexed
  • Employer financial concerns

Reporting DB Pension

T4A Slip

  • Box 22: Tax withheld

Where to Report

Pension and OAS Clawback

Impact on OAS

  • DB pension counts toward OAS clawback
  • May push over threshold ($90,997 in 2024)
  • Pension splitting can help

Strategy

  • Split pension with lower-income spouse
  • Draw less from RRIF if possible
  • Use TFSA for additional needs

Planning Considerations

Before Retirement

  • Understand your pension formula
  • Review survivor options
  • Calculate pension with/without bridge
  • Compare to commuted value if offered

Retirement Year

  • May have partial year of salary + pension
  • Could be high-income year
  • Maximize RRSP in final working year
  • Plan pension start date

In Retirement

  • Optimize pension splitting annually
  • Coordinate with other income sources
  • Monitor OAS clawback
  • Review beneficiary designations
