You’ll usually want a stack of retirement accounts that work together: one (or more) for tax breaks now, one for tax‑free money later, and a flexible bucket you can tap anytime.

Big picture: the account “stack”

In the U.S., most people end up with some combo of:

  1. Employer plan (401(k), 403(b), 457(b), or TSP).
  1. IRA (traditional and/or Roth).
  1. Health Savings Account (HSA) if eligible.
  1. Taxable brokerage account for extra investing and flexibility.

How much you use each depends on your job, income, and tax bracket, but this mix covers almost every “what retirement accounts should I have” question.

Core accounts most people should consider

1. Workplace plan (401(k), 403(b), 457(b), TSP)

If your employer offers one, this is usually your first stop.

  • Pre‑tax (traditional): Lowers taxable income today; withdrawals taxed in retirement.
  • Roth: No tax break now; qualified withdrawals tax‑free later.
  • Often includes an employer match (free money).

Why you probably want it:

  • Easy payroll deductions, high contribution limits, and possible match make it a backbone retirement account.

2. IRA (traditional and/or Roth)

IRAs are individual accounts you open yourself, not through your employer.

  • Traditional IRA : May be tax‑deductible contributions, taxed when withdrawn.
  • Roth IRA : Contribute after‑tax; qualified withdrawals tax‑free.

Why you probably want one:

  • Gives you more investment options than many employer plans.
  • Roth IRA is especially attractive if you expect to be in the same or higher tax bracket in retirement.

3. Health Savings Account (HSA) – stealth retirement account

If you’re on a high‑deductible health plan, an HSA can double as a retirement account.

  • Contributions can be tax‑deductible, growth is tax‑free, and qualified medical withdrawals are tax‑free.
  • In retirement (after a certain age), non‑medical withdrawals just get taxed like a traditional IRA.

Why you might want it:

  • Triple tax advantage makes it one of the most tax‑efficient “retirement” accounts available.

4. Taxable brokerage account

Not technically a retirement account, but crucial for long‑term investing.

  • No contribution limits, no early withdrawal penalties.
  • Taxed along the way (dividends, capital gains), but offers maximum flexibility.

Why you might want it:

  • For goals before traditional retirement age, or when you’ve maxed the tax‑advantaged options.

If you’re self‑employed or a small‑business owner

On top of IRAs and HSAs, you might add:

  • Solo 401(k) : For self‑employed with no employees; high contribution potential.
  • SEP IRA : Simpler setup; employer contributions only.
  • SIMPLE IRA : For small employers; easier than a full 401(k).

These exist to give business owners a way to shelter more income for retirement with relatively manageable admin work.

How people typically prioritize them

A common, simple order of operations (not personal advice, just a widely discussed pattern in forums and guides):

  1. Get the full employer match in your workplace plan.
  2. Fund a Roth or traditional IRA up to the annual limit.
  3. Go back and add more to your workplace plan if you can.
  4. If eligible and you have the cash flow, max the HSA.
  5. Invest extra in a taxable brokerage account.

This approach balances current tax savings, future tax‑free income, and flexibility.

Quick HTML table: common retirement accounts

Account type Where it’s opened Tax treatment (high level) Typical use
Traditional 401(k)/403(b)/TSP/457(b) Through employer Pre-tax contributions, taxed on withdrawal Main workplace retirement savings, often with employer match
Roth 401(k)/403(b)/TSP/457(b) Through employer After-tax contributions, tax-free qualified withdrawals For those expecting similar or higher tax bracket later
Traditional IRA Bank/brokerage of your choice Potentially deductible now, taxed on withdrawal Supplement workplace plan, or main account if no plan
Roth IRA Bank/brokerage of your choice After-tax contributions, tax-free qualified withdrawals Tax-free bucket in retirement, more investment choice
HSA Bank or provider linked to HDHP Tax-deductible in, tax-free growth, tax-free for medical Future medical costs, often used as a “stealth” retirement account
Taxable brokerage Any brokerage No special tax breaks, taxed on dividends/gains Extra investing and flexibility before retirement age
Solo 401(k)/SEP/SIMPLE IRA Brokerages, for self-employed or small employers Generally pre-tax contributions, taxed on withdrawal Let business owners save larger amounts for retirement

Forum-style “story” view

Imagine a typical poster on a money forum in 2026: early 30s, W‑2 job, some side income, confused about “what retirement accounts should I have” while everyone talks about FIRE and Roth ladders.

The top replies almost always walk them through the same structure: grab the match in the employer plan, open a Roth IRA for tax‑free growth, consider an HSA if their health plan allows, and then build a taxable brokerage for flexibility and early retirement options.

If they’re also freelancing or running a small business, people chime in about Solo 401(k)s or SEP IRAs to shelter more income, but the backbone is still that same trio: workplace plan, IRA, and some kind of flexible investing account on the side.

TL;DR

Most people are well served by having:

  • A traditional and/or Roth employer plan (401(k)/403(b)/457(b)/TSP).
  • A Roth or traditional IRA.
  • An HSA if eligible.
  • A taxable brokerage account once tax‑advantaged space is filled.
