Tax-advantaged retirement savings structure used to encourage long-term retirement accumulation through regular contributions and investment growth.
A retirement savings plan (RSP) is a tax-advantaged savings structure designed to help individuals accumulate assets for retirement over time.
The term is broader than any one country’s exact account label. What matters is the core function: contributions receive favorable tax treatment, the assets grow over time, and the structure is meant to support retirement income later.
Retirement savings plans matter because they shape:
how much savers contribute
when taxes are paid
how long money can compound
how retirement withdrawals are treated
That means the plan design itself changes behavior, not just the investment return inside the account.
