2026 Limits at a Glance

Rule2026 limit
Annual contribution$7,000 (under 50) / $8,000 (50+)
Roth income phase-out (single)$150,000–$165,000
Roth income phase-out (married)$236,000–$246,000
Traditional deduction phase-out (covered by workplace plan, single)$79,000–$89,000
💡Still use a Traditional if over Roth limit

Over the Roth income limit? Use the Backdoor Roth strategy: contribute to a non-deductible Traditional IRA, then immediately convert. Legal, common, and effective at any income.

The One Question That Decides Everything

📊The core decision

Do you expect to be in a higher or lower tax bracket at retirement than you are today? • Higher bracket at retirement → Roth wins (pay tax now at the lower rate) • Lower bracket at retirement → Traditional wins (defer tax to the lower-rate future)

Most people in their 20s–30s are in a lower bracket now than they'll be at peak earning years. That makes Roth the default winner for young workers. But it's not that simple — here's how to actually think about it:

  • If you're earning under $50k: Almost certainly Roth — tax rates this low are a gift
  • If you're earning $50k–$100k: Usually Roth, but run the numbers — especially if your employer doesn't offer a match
  • If you're earning $100k–$150k: It depends on state tax, expected retirement income, and whether you max out a 401k too
  • If you're earning $150k+: Roth phase-out kicks in; consider Backdoor Roth or max Traditional first

The Numbers: $6,000/yr for 30 Years

ScenarioRothTraditional
Tax paid upfront (22% bracket)$1,320/yr$0 upfront
Account grows at 7% for 30 years$567,000 tax-free$567,000 pre-tax
Tax paid at withdrawal (22% bracket)$0$124,740
Net after tax$567,000$442,260
📊Same bracket = Roth wins slightly

Even at the same tax rate, Roth comes out slightly ahead because tax-free growth on dividends and capital gains inside the account is worth more over decades.

5 Rules of Thumb That Actually Help

  1. 1Under 40 and earning under $80k? Default to Roth — low rates now, higher rates likely later
  2. 2Already maxing a 401k? Add Roth IRA — diversifies your tax exposure at retirement
  3. 3Expect Social Security + pension? Traditional income may push you into a higher bracket — Roth hedges this
  4. 4Living in a high-tax state planning to retire in a low-tax state? Traditional + move = double win
  5. 5Can't decide? Split 50/50 — you get tax diversification and don't need to predict the future
