Description
Plan your retirement taxes like a pro — and stay on top of them all year long.
RetireSmartIRA answers the questions that take a CPA hours to model: Roth conversions, Social Security claiming, RMDs, IRMAA, ACA cliff, charitable timing. Real numbers in real time. Built for people who want answers, not generic advice.
ANSWER THE QUESTIONS THAT ACTUALLY MATTER
• What if I convert $200K to Roth this year? See federal tax, state tax, and Medicare IRMAA impact instantly.
• When should my spouse and I claim Social Security? Find the strategy that pays the most over both your lifetimes — and protects the survivor.
• How much will my RMDs be in 10 years? Project required distributions for your IRAs, 401(k)s, and inherited IRAs out 5, 10, 15, or 20 years.
• Which year should I do that big charitable gift? Stack it against Roth conversions and see your real tax bill, not an estimate.
SCENARIO BUILDER — Plan in real time
Adjust Roth conversions, IRA withdrawals, pre-tax contributions, and charitable donations with sliders. Every change updates the tax waterfall, federal bracket position, state bracket, and IRMAA tier instantly. See exactly how much room you have before the next bracket — and what crossing it would cost.
KNOW EXACTLY WHAT YOU'LL OWE
One screen shows it all:
• Federal tax (2026 brackets)
• State tax (all 50 states + DC, including California's 13.3% top rate)
• NIIT 3.8% surtax
• IRMAA Medicare surcharges (per person, with cliff distance and savings opportunities)
• ACA Premium Tax Credit and cliff repayment risk
• Standard vs. itemized comparison with SALT cap math
No spreadsheets. No black boxes. Every dollar is traced back to the input that produced it.
SOCIAL SECURITY COUPLES PLANNER
The decision that drives the surviving spouse's check — for life. Compare claiming at 62 vs. FRA vs. 70 for both spouses. See cumulative lifetime benefits, survivor protection, deemed-filing rules, and tax integration in one view. Includes a "Couples Optimization" recommendation based on both your records.
RMD CALCULATOR FOR YOUR IRA AND INHERITED IRAs
Most calculators get inherited IRAs wrong. RetireSmartIRA handles them all:
• Traditional IRA / 401(k) RMDs starting at age 73 (or 75 under SECURE 2.0)
• Spousal inherited IRAs with deferral options
• Non-eligible designated beneficiaries (the 10-year rule)
• Eligible designated beneficiaries (stretch IRA holdouts)
• Pre-RBD vs. post-RBD decedent treatment
• Minor children stretching to majority
Project annual RMDs out 20 years with adjustable growth assumptions. Stack household RMDs across both spouses.
WHO IT'S FOR
• Pre-retirees ages 55–73 evaluating Roth conversion windows
• Retirees managing RMDs, IRMAA, and the ACA cliff
• Couples planning Social Security claiming strategy
• Federal/military households (FERS, military retirement state exemptions, VA Disability)
• Anyone inheriting an IRA and needing to plan the 10-year drain
• Tax-aware investors who want to minimize lifetime tax, not just this year's
