Key Takeaways
- 1.A 12-week severance on a $105,000 salary is a $24,231 lump sum. CRA requires 30% flat withholding ($7,269), but the true marginal rate is 33.8% — expect to owe approximately $918 at filing.
- 2.Service Canada allocates the lump sum over 12 weeks based on normal weekly earnings. Add the 1-week waiting period: first EI payment arrives 13 weeks after your last day.
- 3.With all service after 1996, the eligible retiring allowance RRSP transfer is $0. The only RRSP absorption route uses regular contribution room.
- 4.Contributing the full $24,231 to RRSP eliminates all tax on the severance, triggers a $7,269 refund of the withholding, and shelters the funds for tax-deferred growth.
- 5.EI maximum weekly benefit for 2025 is $695/week ($2,780/month). At $105,000 salary, you are above the $65,700 MIE and receive the maximum rate.
The Scenario: Maria, Calgary, $105,000 Salary, 12-Week Package
This worked example follows a single scenario from layoff through severance taxation, EI deferral, and RRSP optimization. No existing calculator page integrates all three variables — severance tax, EI timing, and RRSP absorption — into one Alberta-specific walkthrough.
- Name: Maria
- Province of residence: Alberta (Calgary)
- Annual salary: $105,000
- Years of service: 8 (started 2017)
- Termination: Without cause, effective October 31, 2025
- Salary earned Jan–Oct: $87,500 (10 months)
- Severance: 12-week lump sum = $24,231
- Total 2025 employment income: $111,731
- RRSP contribution room available: $24,500 (accumulated)
- Other income in 2025: $0
Step 1: Calculate the Severance Amount
Severance is typically expressed in weeks of regular pay. Maria's 12-week package uses her weekly salary as the base:
Annual salary: $105,000
Weekly salary: $105,000 ÷ 52 = $2,019.23
12-week severance: $2,019.23 × 12 = $24,231
Alberta Employment Standards Code minimum. With 8 years of service, the statutory minimum termination notice (or pay in lieu) is 6 weeks under the Alberta Employment Standards Code. Maria's 12-week package exceeds this floor. However, common-law reasonable notice for an 8-year employee in a mid-level role could be significantly higher — potentially 8 to 14 months depending on age, position, and re-employment prospects. Always consult an employment lawyer before accepting a severance offer.
Step 2: CRA Lump-Sum Withholding vs. True Marginal Rate
When an employer pays severance as a lump sum, the CRA requires flat-rate withholding rather than the graduated rates used on regular payroll. For amounts over $15,000, the withholding rate is 30% in all provinces except Quebec.
Lump-sum severance: $24,231
CRA withholding rate (over $15,000): 30%
Tax withheld at source: $24,231 × 30% = $7,269
Net cash received by Maria: $24,231 − $7,269 = $16,962
But 30% is only a rough approximation. The actual tax on the severance depends on Maria's total income for the year and where the severance lands in the graduated federal and Alberta brackets. For a similar Ontario analysis, see our Ontario severance tax calculator for an $85,000 lump-sum payout.
True Marginal Rate on the Severance
Maria earned $87,500 in salary before layoff. The $24,231 severance stacks on top, bringing her total employment income to $111,731. The severance spans two federal brackets:
| Income Layer | Federal | Alberta | Combined |
|---|---|---|---|
| $87,500 – $114,750 (first $27,250 of severance) | 20.5% | 10% | 30.5% |
| $114,750 – $111,731 (not reached) | 26% | 10% | 36% |
Since Maria's total income of $111,731 stays below the $114,750 federal bracket threshold, the entire severance is taxed at the 30.5% combined rate (20.5% federal + 10% Alberta).
True marginal tax on $24,231 severance: 30.5%
Actual tax on severance: $24,231 × 30.5% = $7,390
CRA withheld at source: $7,269
Shortfall owing at filing: $7,390 − $7,269 = $121
In this scenario, the 30% withholding is almost perfectly matched to the true 30.5% rate — Maria owes only $121 at filing. But if she had been laid off later in the year with higher salary income, the severance could push her above $114,750 into the 36% combined bracket, creating a larger gap between withholding and actual tax.
The year-end tax surprise. If Maria had earned her full $105,000 salary before receiving severance, total income would be $129,231. The portion from $114,750 to $129,231 ($14,481) would face the 36% combined rate instead of 30.5%. CRA still withholds only 30% — leading to approximately $918 owing at filing. The higher your pre-severance income, the larger this gap. This is why lump-sum withholding rates can understate actual tax.
Step 3: Retiring Allowance — Eligible vs. Non-Eligible Portion
CRA classifies severance for loss of employment as a “retiring allowance.” A retiring allowance has an eligible portion that can be transferred directly to an RRSP without using contribution room:
| Period | Eligible Transfer | Maria's Years |
|---|---|---|
| Years of service before 1996 | $2,000 per year | 0 years |
| Years of service before 1989 (no pension) | Additional $1,500 per year | 0 years |
| Total eligible RRSP transfer | — | $0 |
Maria started working in 2017. With zero years of service before 1996, her eligible retiring allowance transfer is $0. The entire $24,231 is the non-eligible portion, reported in Box 27 of the T4A.
This means the only RRSP absorption route available is using regular RRSP contribution room. Maria has $24,500 of accumulated room — enough to absorb the full severance. For a deeper look at RRSP optimization strategies for Alberta earners, see our RRSP vs. TFSA comparison for a $180,000 Alberta earner.
Step 4: EI Benefit Calculation and Severance Deferral
Service Canada treats a lump-sum severance as “earnings allocation” — the severance amount is divided by normal weekly earnings to determine how many weeks EI is deferred. This is the government's “no double-dipping” rule: you cannot collect EI while severance covers the same period.
EI Deferral Calculation
Severance: $24,231
Normal weekly earnings: $2,019.23
Allocation weeks: $24,231 ÷ $2,019.23 = 12 weeks
Plus: 1-week standard waiting period
First EI payment: Week 14 after last day of work
Maria should file her EI application immediately after her last day. Service Canada processes the claim during the allocation period, so there is no delay once the deferral ends.
EI Weekly Benefit Amount
2025 Maximum Insurable Earnings (MIE): $65,700
Maria's salary: $105,000 (above MIE)
Weekly insurable earnings: $65,700 ÷ 52 = $1,263.46
EI benefit rate: 55%
Weekly benefit: $1,263.46 × 55% = $695/week
Monthly benefit (approx.): $695 × 4.33 = $3,009/month before tax
EI benefits are taxable income. At Maria's marginal rate of 30.5%, the after-tax monthly EI is approximately $2,091. This represents a 76% income drop from her pre-layoff monthly take-home. Planning for this gap is critical — the severance lump sum may need to bridge the difference.
Monthly Cash-Flow Timeline
| Period | Income Source | Monthly Cash |
|---|---|---|
| Month 1–3 (weeks 1–13) | Severance covers (lump sum already received) | $5,654 from lump sum* |
| Month 4 onward (week 14+) | EI regular benefits | $3,009 before tax |
*$16,962 net lump sum spread over 3 months for budgeting purposes. Maria received the full amount upfront but should pace spending to bridge the EI gap.
Step 5: Three RRSP Scenarios — Net Payout Comparison
The RRSP deduction is the primary tool to reduce tax on severance for workers with post-1996 service. Here are three scenarios showing how RRSP contributions change the after-tax outcome. For a related year-end RRSP strategy, see our year-end RRSP top-up calculator.
Scenario A: No RRSP Contribution
Gross severance: $24,231
True marginal tax (30.5%): −$7,390
Net after-tax value: $16,841
CRA withheld at source: $7,269
Balance owing at filing: $121
Scenario B: $12,000 RRSP Contribution (Partial Absorption)
Gross severance: $24,231
RRSP contribution: −$12,000
Remaining taxable severance: $12,231
Tax on remaining (30.5%): −$3,730
Net cash: $8,501
RRSP value: $12,000
Total value: $20,501
Tax saved vs. Scenario A: $3,660
Refund at filing: $3,539 (over-withheld)
Scenario C: Full $24,231 RRSP Contribution
Gross severance: $24,231
RRSP contribution: −$24,231
Remaining taxable severance: $0
Additional tax on severance: $0
Net cash: $0 (plus $7,269 refund at filing)
RRSP value: $24,231
Total value: $31,500
Tax saved vs. Scenario A: $7,390
In Scenario C, the mechanics work like this: the employer withholds $7,269 and deposits $16,962 in Maria's account. Maria contributes $16,962 to her RRSP from the net amount, plus $7,269 from savings to reach the full $24,231. At filing, the RRSP deduction eliminates all tax on the severance, and the $7,269 over-withholding is refunded. The $7,269 from savings is fully recovered.
Side-by-Side Comparison
| Factor | No RRSP | $12K RRSP | Full RRSP |
|---|---|---|---|
| RRSP contribution | $0 | $12,000 | $24,231 |
| Tax on severance | $7,390 | $3,730 | $0 |
| Net cash (after filing) | $16,841 | $12,040 | $7,269 |
| RRSP balance | $0 | $12,000 | $24,231 |
| Total value (cash + RRSP) | $16,841 | $24,040 | $31,500 |
RRSP amounts represent pre-tax value. Withdrawals will be taxed at Maria's marginal rate in the year of withdrawal. The benefit is maximized if withdrawals occur in a year with lower income (e.g., during unemployment or retirement).
Step 6: Federal + Alberta Tax Breakdown on Total 2025 Income
For completeness, here is the full tax calculation on Maria's total 2025 income of $111,731 (salary $87,500 + severance $24,231) under Scenario A (no RRSP contribution).
Federal Tax (2025 Rates)
| Bracket | Rate | Taxable Amount | Tax |
|---|---|---|---|
| $0 – $57,375 | 15% | $57,375 | $8,606 |
| $57,375 – $111,731 | 20.5% | $54,356 | $11,143 |
| Gross federal tax | — | — | $19,749 |
| Less: basic personal credit (15% × $16,129) | — | — | −$2,419 |
| Net federal tax | — | — | $17,330 |
Alberta Provincial Tax (2025 Rates)
| Bracket | Rate | Taxable Amount | Tax |
|---|---|---|---|
| $0 – $111,731 | 10% | $111,731 | $11,173 |
| Gross Alberta tax | — | — | $11,173 |
| Less: basic personal credit (10% × $21,003) | — | — | −$2,100 |
| Net Alberta tax | — | — | $9,073 |
Alberta has the simplest provincial tax structure: a flat 10% on the first $148,269 of taxable income. This makes marginal rate calculations straightforward compared to provinces with more brackets. For a multi-bracket Alberta tax analysis at higher incomes, see our OAS clawback calculator for an Alberta retiree at $110,000.
Total 2025 Tax (Scenario A — No RRSP)
Net federal tax: $17,330
Net Alberta tax: $9,073
Total 2025 tax: $26,403
Effective rate on $111,731: 23.6%
Marginal rate on the last dollar: 30.5% (20.5% federal + 10% Alberta)
Lump Sum vs. Salary Continuance: Which Is Better?
Employers sometimes offer a choice between a lump-sum payment and salary continuance (continued pay at regular intervals). The tax and EI implications differ:
| Factor | Lump Sum | Salary Continuance |
|---|---|---|
| Tax withholding | Flat 30% (over $15K) | Regular payroll deductions |
| EI deferral | Allocated over weeks, then EI starts | No EI until continuance ends |
| CPP contributions | No CPP on retiring allowance | CPP continues on regular pay |
| RRSP strategy | Can contribute immediately | Must wait for each payment |
| Mitigation | Employer duty typically ends at payout | May end if you find new job |
The lump sum is generally preferred when: you have RRSP room to absorb it, you want cash flexibility, or you plan to negotiate a new role before the continuance period ends (since many continuance arrangements include a mitigation clause that reduces or eliminates payments if you find new employment). For more on RRSP contribution strategies, see our Alberta FHSA + RRSP combo calculator.
Practical Steps After Layoff
- Do not sign the severance offer immediately. In Alberta, you typically have a reasonable period (often 5–10 business days) to consider. Consult an employment lawyer to assess whether the offer meets common-law reasonable notice standards.
- File your EI application on your first day without work. The allocation period runs from your last day of employment regardless of when you apply, but filing early ensures processing happens during the deferral window.
- Check your RRSP contribution room on My CRA Account. Your Notice of Assessment from the prior tax year shows your available room. If you have sufficient room, contribute the severance (or a portion) within 60 days of year-end to claim the deduction on this year's return.
- Request a T4A from your employer. The retiring allowance should be reported separately from regular employment income. The eligible and non-eligible portions should be broken out in the correct boxes.
- Budget for the EI income gap. At $695/week ($3,009/month before tax), EI replaces roughly 34% of pre-layoff gross income. The severance lump sum should bridge the first 13 weeks and supplement EI afterward.
