Types of investment accounts
The main containers are a workplace plan such as a 401(k), an IRA (traditional or Roth), an HSA if you have a qualifying health plan, and a taxable brokerage account. The contribution you can deduct, the tax on growth, and the tax on the way out are what differ.

Workplace plan
A 401(k), 403(b), or similar plan takes payroll deferrals. Traditional deferrals lower taxable income now and are taxed on withdrawal. Roth deferrals do not lower it now and are tax-free later if the rules are met. The employer match is often the highest-return dollar available, because it is extra pay for participating.
IRA
An IRA is an account you open yourself. Deductibility of a traditional IRA, and the ability to contribute to a Roth IRA, depend on income and on whether you are covered by a workplace plan. Those thresholds change. Check the current tax year before you assume you qualify.
HSA
A health savings account, when you are eligible, can be pre-tax, grow untaxed, and come out untaxed for qualified medical bills. Some households invest the balance after a cash cushion and treat it as a medical reserve for later life. It is not available on every health plan.
Taxable brokerage
No contribution limit tied to a retirement rule, and no penalty for spending the money. Dividends and realized gains are taxable. This is the usual account once workplace and IRA room is used, or when the goal is not retirement.
Common questions
Is a savings account an investment account?
It is a cash account. It belongs in net worth and in the emergency fund. It is the wrong place for money you will not need for decades, because cash has historically lagged a diversified portfolio after inflation.
