Common misconceptions

Many people first hear "Roth" and think of it means you pay taxes on the money now, so withdrawals later are tax-free. The Roth label — named after Senator William Roth who created it — always signals after-tax contributions and tax-free withdrawals, whether it's a Roth IRA or a Roth 401k. Keep that framing throughout this journey. Many people first hear "Contribution Limits" and think of the maximum dollar amount you are legally allowed to deposit into the account each year. For 2024 the IRA limit is $7,000 (plus a $1,000 catch-up if you are 50 or older) and the 401k limit is $23,000 — these are hard annual ceilings on new money you add, not on growth. Keeping this distinction clear matters when comparing Roth IRA income phase-outs against 401k limits.

Common questions

Is it true that money contributed to a traditional 401k reduces your taxable income in the year you contribute it?
Yes. Traditional 401k contributions are pre-tax, lowering your taxable income now and deferring taxes until withdrawal.
When do you pay income tax on money in a Roth IRA?
When you contribute (upfront). Roth contributions are made with after-tax dollars, so growth and qualified withdrawals are completely tax-free.
Is it true that in 2024, the combined IRA contribution limit (Roth + Traditional) is $7,000 for most people under 50?
Yes. The IRS sets a single combined limit across all your IRAs; contributing $7,000 to a Roth leaves $0 room for a Traditional IRA that year.
