What is a Roth IRA and how does it work?

Retirement & 401(k)beginner3 answers · 7 min readUpdated February 28, 2026

Quick Answer

A Roth IRA is a retirement account funded with after-tax dollars that grows tax-free. You contribute up to $7,000 in 2026 ($8,000 if 50+) with money you've already paid taxes on, but all future growth and qualified withdrawals after age 59½ are completely tax-free. Unlike traditional IRAs, there are no required minimum distributions.

What is a Roth IRA?


A Roth IRA is a retirement account where you contribute money you've already paid taxes on, but then enjoy completely tax-free growth and withdrawals in retirement. Think of it as "pay taxes now, never pay taxes again" on this money.


How Roth IRA contributions work


Unlike a traditional IRA or 401(k), Roth contributions don't reduce your current paycheck taxes. You contribute after-tax dollars, meaning money that's already been through payroll withholding.


Example: $60,000 salary, 22% tax bracket

  • You want to contribute $5,000 to a Roth IRA
  • This $5,000 comes from money you've already paid ~$1,100 in taxes on
  • No additional tax deduction — your W-2 taxes stay the same
  • But this $5,000 will grow tax-free for decades

  • 2026 Roth IRA contribution limits and income restrictions


    Contribution Limits:

  • Under 50: $7,000 annually
  • Age 50+: $8,000 annually

  • Income Limits (2026):

  • Single filers: Phase-out from $138,000 - $153,000
  • Married filing jointly: Phase-out from $218,000 - $228,000

  • Example phase-out: If you're single earning $145,000, you can contribute about $3,700 (roughly half the limit).


    The power of tax-free growth


    Here's where Roth IRAs become incredibly powerful. Every dollar of growth is yours to keep — no taxes ever.


    25-year-old contributing $5,000 annually:

  • Total contributions over 40 years: $200,000
  • Account value at 65 (7% growth): ~$1.1 million
  • Traditional IRA: Pay taxes on ~$900,000 of growth (~$200,000+ in taxes)
  • Roth IRA: Pay $0 in taxes on any of it

  • Roth vs. Traditional IRA comparison



    Unique Roth IRA withdrawal rules


    Roth IRAs have more flexible withdrawal rules than other retirement accounts:


    Contributions: You can withdraw your original contributions anytime, tax and penalty-free (since you already paid taxes).


    Growth/earnings: Must wait until age 59½ and account must be 5+ years old to avoid taxes and penalties.


    Example: You contribute $7,000 annually for 5 years ($35,000 total). Your account grows to $45,000. You can withdraw up to $35,000 anytime without taxes or penalties.


    Who should consider a Roth IRA?


    Ideal candidates:

  • Young professionals expecting higher future tax rates
  • People wanting tax diversification in retirement
  • Those who want to avoid required minimum distributions
  • Anyone wanting flexibility to access contributions if needed

  • Less ideal:

  • High earners who need immediate tax deductions (consider traditional 401(k) first)
  • People expecting to be in much lower tax brackets in retirement

  • What you should do


    1. Check if your income qualifies for Roth IRA contributions

    2. Open a Roth IRA with a low-cost provider (Vanguard, Fidelity, Schwab)

    3. Set up automatic monthly contributions — $583/month gets you to the $7,000 limit

    4. Use our paycheck calculator to see how Roth contributions affect your take-home pay (spoiler: they don't change your taxes)

    5. Consider Roth if you're young — the tax-free growth over decades is powerful


    Key takeaway: A Roth IRA offers tax-free growth and withdrawals in retirement, making it especially powerful for younger workers who have decades for their money to grow — a 25-year-old contributing $7,000 annually could have over $1 million tax-free at retirement.

    New workers early in their careers who may benefit most from Roth IRAs

    Why Roth IRAs are perfect for new graduates


    As someone starting your career, a Roth IRA might be your best retirement savings vehicle. You're likely in a lower tax bracket now than you'll be in 30-40 years, making "pay taxes now" a smart strategy.


    Your tax situation early in career


    Typical entry-level scenario:

  • Starting salary: $45,000-$65,000
  • Tax bracket: Likely 12% or 22%
  • Future earnings potential: Much higher
  • Current tax rate vs. retirement tax rate: Probably paying less now

  • Example: $50,000 starting salary

  • Contributing $3,000 to Roth IRA
  • You've already paid ~$330 in taxes on this money (11% effective rate)
  • In retirement, this money would be taxed at potentially 22-24%
  • Tax savings in retirement: Potentially $500+ per year on just this contribution

  • Starting small but thinking big


    Don't feel pressured to contribute the full $7,000 limit immediately. Even small amounts make a massive difference over 40+ years.


    $200/month Roth IRA contribution at age 22:

  • Annual contribution: $2,400
  • Total contributed over 43 years: $103,200
  • Value at retirement (7% growth): ~$830,000
  • All $830,000 is tax-free in retirement

  • $500/month starting at age 25:

  • Annual contribution: $6,000
  • Value at retirement: ~$1.37 million tax-free

  • Advantages for young workers


    Time is your superpower: Compound growth over 40+ years turns modest contributions into substantial wealth.


    Career flexibility: Roth IRA contributions can be withdrawn penalty-free if needed for emergencies (though not recommended).


    Future tax protection: As your income grows and tax rates potentially increase, you'll appreciate having tax-free money in retirement.


    Getting started action plan


    1. Open a Roth IRA with any major brokerage — most have $0 minimum to start

    2. Start with what you can afford — even $50-100/month makes a difference

    3. Increase contributions with raises — boost by 1-2% each year

    4. Choose simple investments — target-date funds are perfect for beginners

    5. Automate everything — set up automatic monthly transfers


    Key takeaway: Young workers are in the perfect position to benefit from Roth IRAs — contributing just $200/month starting at age 22 could result in over $800,000 tax-free at retirement.

    High-income professionals who may face income restrictions or need backdoor strategies

    Roth IRA strategies for high earners


    As a high-income professional, direct Roth IRA contributions may be restricted, but there are legal strategies to access these powerful tax-free accounts through backdoor conversions and careful planning.


    Income limitation reality


    2026 Roth IRA phase-out ranges:

  • Single: $138,000 - $153,000
  • Married filing jointly: $218,000 - $228,000

  • If your income exceeds these ranges, you cannot contribute directly to a Roth IRA. However, the backdoor Roth strategy remains available.


    The backdoor Roth IRA process


    This IRS-approved method allows high earners to make Roth contributions indirectly:


    1. Contribute $7,000 to traditional IRA (non-deductible)

    2. Immediately convert to Roth IRA (usually within days)

    3. Pay taxes only on any growth during the brief holding period

    4. Result: $7,000 in Roth IRA growing tax-free


    Tax impact example at $200,000 income:

  • Traditional IRA contribution: $7,000 (no deduction due to 401(k) coverage)
  • Conversion to Roth: No additional taxes if done immediately
  • Annual tax-free retirement savings: $7,000

  • Why high earners should consider Roth strategies


    Tax diversification: Having both pre-tax (401k) and after-tax (Roth) money gives flexibility to manage retirement tax brackets.


    Estate planning benefits: Roth IRAs have no required minimum distributions, making them excellent for wealth transfer.


    Hedge against future tax increases: With growing federal debt, tax rates may rise — Roth accounts provide protection.


    Advanced strategy: Mega backdoor Roth


    If your 401(k) plan allows after-tax contributions beyond the $23,500 limit:


  • Total 401(k) limit (all sources): $70,000 in 2026
  • After maxing employer match and your $23,500, contribute after-tax dollars
  • Convert after-tax 401(k) money to Roth IRA
  • Potential result: $40,000+ annually in Roth accounts

  • Strategic considerations


    Current vs. future tax rates: At high income levels, you're likely in your peak earning (and tax) years, making traditional pre-tax savings more immediately valuable.


    Optimal approach: Maximize 401(k) for immediate tax savings, then use backdoor Roth for additional tax-free growth.


    Professional guidance: Complex rules around backdoor conversions require careful execution — consider working with a tax professional.


    Key takeaway: High earners can access Roth IRA benefits through backdoor conversions, potentially building substantial tax-free retirement wealth while maintaining current tax advantages from 401(k) contributions.
