What Is a 401(k)? (And the Canadian Equivalent)
A 401(k) is a United States retirement plan you get through your employer. Contributions usually come straight out of your paycheck before tax, the money grows tax-deferred, and you're taxed when you withdraw it in retirement. Many employers sweeten it with a matching contribution. In Canada, the equivalent is the RRSP, often as a group RRSP at work.
How a 401(k) works
Like other retirement accounts, a 401(k) is a tax wrapper, not an investment itself — inside it you hold funds or other investments. What defines it is the tax treatment and the fact that it's tied to your job:
- Pre-tax contributions. Money is deducted from your pay before income tax, which lowers your taxable income for the year. (Some plans also offer a Roth 401(k) option using after-tax money.)
- Tax-deferred growth. Investments grow without being taxed year to year.
- Taxed on withdrawal. You pay income tax when you take the money out in retirement, ideally when your income may be lower.
- Annual limits and early-withdrawal penalties. There's a cap on yearly contributions, and pulling money out early usually triggers taxes plus a penalty.
The employer match: the headline feature
The reason 401(k)s get so much attention is the employer match. Your company adds money based on what you put in — a common structure is matching your contributions up to a set percentage of your salary. Because it's extra money you wouldn't otherwise receive, financial writers often describe capturing the full match as a high priority. Matches frequently come with a vesting schedule, meaning you must stay employed for a certain time before the matched money is fully yours.
The Canadian equivalent: the RRSP
Canada doesn't have 401(k)s. The closest match is the Registered Retirement Savings Plan (RRSP), and when an employer offers one it's usually a group RRSP:
| 401(k) (US) | RRSP / group RRSP (Canada) | |
|---|---|---|
| Offered by | Employer | Anyone; group version via employer |
| Contributions | Pre-tax, lower taxable income | Tax-deductible, lower taxable income |
| Growth | Tax-deferred | Tax-deferred |
| Withdrawals | Taxed as income | Taxed as income |
| Employer match? | Common | Sometimes, in group RRSPs |
Canada's other main registered account, the TFSA, works the opposite way — after-tax money in, tax-free out — closer to a Roth-style plan than a 401(k).
Why these accounts matter
The combination of tax deferral and, where available, an employer match, means more money stays invested and working through compounding. That said, the account only shelters tax and adds a possible match — it doesn't protect the investments inside from falling in value.
The bottom line
A 401(k) is a US, employer-based retirement plan: pre-tax contributions, tax-deferred growth, taxed withdrawals, and often a valuable employer match. Canadians use the RRSP — frequently as a group RRSP at work — for the same tax-deferred purpose, with the TFSA covering the tax-free-growth side. Understanding the 401(k) mainly helps decode US articles and job offers.

Frequently asked
What is a 401(k) in simple terms?
A 401(k) is a US retirement plan offered through your employer. Money is taken from your paycheck before tax and invested, it grows tax-deferred, and you pay tax when you withdraw it in retirement. Many employers also add a matching contribution, which is extra money on top of your own.
What is the Canadian equivalent of a 401(k)?
The closest Canadian equivalent is the RRSP (Registered Retirement Savings Plan), and specifically a group RRSP when it's offered through an employer. Like a 401(k), contributions reduce your taxable income now, growth is tax-deferred, and withdrawals are taxed later — and some employers match group RRSP contributions.
What is an employer match?
An employer match is money your company adds to your retirement account based on what you contribute — for example, matching your contributions up to a set percentage of your pay. It's effectively additional compensation for participating, though it often comes with rules about how long you must stay to keep it.
Do Canadians have a 401(k)?
No — the 401(k) is a US plan tied to US tax law. Canadians save for retirement mainly through the RRSP (including employer group RRSPs) and the TFSA. This guide explains the 401(k) mainly so US financial articles and job offers make sense.
