LESSON 1.5
6 min learning time

Investment Accounts

The account wrapper decides your tax treatment and your access rules.

Learning objectives

  • Understand how the account type sets tax treatment and access (U.S. examples)
  • See why the order of funding accounts can matter
  • Know when to get personal tax advice

The main U.S. wrappers

Availability and rules differ by country; these are the common U.S. categories.

  • Taxable brokerage account (U.S.): full flexibility; capital gains are generally taxed when realised by a sale, while interest, dividends and fund distributions are generally taxable in the year paid — rising value you have not sold is generally not taxed each year
  • Traditional IRA / 401(k): contributions may reduce taxable income now, withdrawals taxed later
  • Roth IRA / Roth 401(k): contributions taxed now, qualified withdrawals generally tax-free later
  • Employer plans: often include matching contributions and a limited fund menu
  • Education and health accounts: tax advantages tied to specific uses

Why order matters

Many investors prioritise an employer match first, because it is an immediate addition to contributed capital, then tax-advantaged accounts, then taxable accounts. The right order depends on your circumstances.

Not advice

Contribution limits, eligibility and rules change and differ by jurisdiction. Confirm current rules and consider a qualified professional for your own situation.

Why this matters

The same investments in a different account can produce noticeably different after-tax results.
