Build a remote-worker investing system around cash reserves, account priorities, diversified investing, tax records, and employer-equity risk.

Compare index mutual funds and ETFs in taxable accounts using turnover, distributions, trading costs, and recordkeeping instead of assuming one wrapper always wins.

Understand the direct-transfer, account-age, annual-limit, lifetime-limit, and five-year contribution rules for 529-to-Roth IRA rollovers.

Understand qualified dividends, the holding-period rule, Form 1099-DIV, and why dividend tax treatment should not drive an investment plan.

Use an account-first framework for tax-efficient investing: capture matches, choose retirement accounts, use HSAs when eligible, then optimize taxable investing.

Build a durable long-term investing system with goals, cash reserves, a diversified allocation, automatic contributions, and a rebalancing rule.
