Before you open a brokerage account, decide which account type you need (IRA first, then taxable), compare the top brokerages, and understand what fees you’ll actually pay. The wrong choice can cost you thousands in fees over time.
6 Things to Check Before Opening
| # | Check This | Why It Matters |
|---|---|---|
| 1 | Max out tax-advantaged accounts first | IRA and 401(k) growth is tax-free or tax-deferred |
| 2 | Compare fees and commissions | $0 commissions are standard, but fund expense ratios vary |
| 3 | Check available investment options | Make sure your preferred funds and ETFs are available |
| 4 | Review account minimums | Most major brokerages now require $0 |
| 5 | Understand the tax implications | Taxable accounts require annual tax reporting |
| 6 | Check SIPC and additional insurance coverage | Protects your assets if the brokerage fails |

The Bottom Line
Opening a brokerage account takes about 15 minutes at Fidelity, Schwab, or Vanguard — all three are excellent choices with $0 commissions and low-cost index funds. Before you open a taxable account, make sure you’ve maxed out tax-advantaged options first (401(k) match, Roth IRA). The most important decision isn’t which brokerage — it’s starting early and investing consistently in low-cost index funds.
