The Problem

Individuals with complex retirement portfolios—multiple IRAs, 401(k)s, inherited accounts, and brokerage holdings—face intricate tax rules like the pro-rata rule, backdoor Roth eligibility, RMDs, and LTCG optimization that interact in non-obvious ways. Mistakes like accidentally contributing to a Roth over the income limit, triggering pro-rata tax on backdoor conversions, or failing to plan inherited IRA distributions can cost thousands in avoidable taxes. Most people only discover these errors at tax time, when options to fix them are limited.

Potential Solution

A SaaS tool that ingests a user's full retirement account picture—account types, balances, income, filing status, state—and runs scenario simulations across strategies: backdoor Roth conversions, recharacterizations, reverse rollovers, Roth conversion ladders, LTCG harvesting, and RMD planning. The tool surfaces actionable step-by-step recommendations with estimated tax impact for each action, flags pro-rata exposure before it becomes a problem, and generates IRS form guidance (e.g., Form 8606 instructions). It updates dynamically as users input life changes like job transitions, inheritances, or early retirement timelines.

Why Now?

The number of Americans with six-figure retirement balances has surged alongside FIRE movement growth, and income thresholds for Roth eligibility have not kept pace with wage inflation, pushing more middle-to-upper-middle earners into complex workaround territory. Tax law complexity around inherited IRAs (SECURE 2.0 Act changes) and Roth conversion strategies has intensified demand for personalized, scenario-based planning tools that go beyond what generic tax software provides.

MFJ $246k AGI, accidentally contributed to Roth—returning excess and doing backdoor, correct approach?

May 2, 2026

Hello, Married filing jointly with AGI \~246k for 2025. My wife and I both contributed $7k directly to Roth IRAs (didn’t realize we were over the income limit). I also did a $7k non-deductible Traditional IRA contribution and filed Form 8606. I’m now fixing it by doing a “return of excess contribution” on both Roth IRAs (about $8.3k each including earnings), with no tax withholding, and then planning to proceed with backdoor Roth going forward. Does that sound like the correct way to clean this up without penalties or amending?

Rollover from retirement account and backdoor Roth conversion

r/taxMay 2, 2026

I perform a backdoor Roth conversion each year by contributing to a traditional IRA and then converting it to a Roth IRA shortly afterward. However, I may be leaving my current position this year and plan to roll over my funds from the Thrift Savings Plan (similar to a 401(k)) into IRAs. I understand that having both rollover funds in a traditional IRA and making new traditional IRA contributions (for backdoor Roth conversion) could complicate the tax situation, particularly due to pro-rata rules. Given this, would it be advisable to roll over my entire TSP balance into a brokerage account if I do not plan to make IRA contributions at that same brokerage this year? Additionally, should I keep the IRA used for backdoor Roth conversions separate from the IRA that holds the TSP rollover funds (e.g., at different brokerage firms) to simplify tax reporting?

Over income for Roth IRA (2025, first time MFJ) sanity check on backdoor fix

r/taxMay 2, 2026

Hey all, looking for a sanity check here. Before anyone say this is AI, i used gpt to go over grammar and sentences. For the 2025 tax year, it’s the first time my wife and I are filing jointly (doing taxes now), and I realized our combined income puts us over the Roth IRA limit. I had already contributed the full amount to a Roth for 2025, so now I’m trying to fix it correctly. From what I understand, the right approach is: \- Recharacterize the 2025 Roth contribution → Traditional IRA \- Then convert it back to Roth (backdoor) Some details: \- By the time I recharacterize, the contribution will have some gains (roughly $1k) \- I already completed a backdoor Roth for 2026 earlier this year \- My Traditional IRA balance is currently $0 (everything has been converted) My understanding so far: \- Recharacterization itself isn’t taxable \- When I convert, I only pay tax on the gains ($1k) \- I can convert the full amount (contribution + gains) \- Since my Traditional IRA is $0 at year-end, pro-rata shouldn’t apply Questions: 1. Does this all sound correct? 2. Since both conversions (fixing 2025 + my 2026 backdoor) happen in 2026, do they just get combined on my 2026 taxes? 3. Anything I should watch out for (forms, timing, common mistakes)? Just want to make sure I handle this cleanly and don’t create a bigger issue later. Appreciate any input.

Roth conversion strategy with help from inherited IRAs

r/personalfinanceMay 2, 2026

Ok smart reddit finance folks, here is my situation. I know I should convert traditional IRA/401k monies into my Roth IRA, starting next year especially since I will retire at the end of this year and I'll turn 59 next year. I also understand that the best strategy is to pay the tax using separate money, such as from my brokerage account. That's better than converting $100K and ending up with only $80K in the Roth and $20K going to taxes. Separately, for many years I've been taking RMDs from a large, inherited IRA (non-spouse, pre-2020). I don't love the idea of using all my brokerage account funds to pay the Roth conversion tax. How can I figure out if it's to my advantage to withdraw larger amounts from the inherited IRA and use THAT to cover my conversion taxes? There must be some formula or rule of thumb...? Any help is appreciated. Thanks!
