Backdoor Roth IRA Conversion - First Timer Checking Process
Hey everyone, I'm attempting my first backdoor Roth IRA and want to make sure I don't mess it up. I've been putting money into a traditional IRA at Fidelity throughout this year that already contained some funds from prior years. My new contributions have been invested and grown a bit in value. Since my income exceeds the Roth IRA limits, I'm trying to do a backdoor conversion for just the money I put in this year. Fidelity offers an option to convert any amount I choose to my existing Roth IRA account. But I'm confused about a few things. Should I only convert the contribution limit for 2024 ($7,000)? Or do I need to include the gains my contributions earned this year too? I'm guessing I'll be taxed on whatever amount I convert as regular income - is this how the pro-rata rule works in my situation? For context, all the money in the account before 2024 is pre-tax (roughly $55k), and I contributed the max $7,000 this year. Thanks for any help!

The backdoor Roth process can definitely be confusing the first time! Let me clarify a few points for you. When doing a backdoor Roth conversion, you need to understand how the pro-rata rule works. Since you already have pre-tax funds in your traditional IRA ($55k plus your new $7,000), the IRS won't let you just convert the new contributions. Instead, they consider all your IRA money as one pool. The formula is: (Taxable amount of conversion) = (Conversion amount) × (Total after-tax money in all IRAs ÷ Total value of all IRAs) So if you convert $7,000, you'll be taxed based on the proportion of after-tax to total IRA money. Ideally, for a clean backdoor Roth, you wouldn't have any pre-existing traditional IRA funds. For future years, consider making non-deductible contributions to a traditional IRA (file Form 8606) and then immediately converting to Roth before any gains occur. If possible, look into rolling your existing pre-tax IRA funds into a 401(k) to avoid the pro-rata rule.

•So wait, I'm confused. If I have $20k in a Traditional IRA already and want to add $7k and do the backdoor, I can't just convert the $7k? Does this mean I'm stuck and can't do backdoor Roths until I move all my existing IRA money somewhere else?

•With pre-existing IRA funds, you can still do a backdoor Roth, but you'll pay taxes proportionally. Using your example with $20k already in a Traditional IRA and adding $7k non-deductible contribution, if you convert just the $7k, about 74% of the conversion would be taxable [(total IRA balance of $27k minus non-deductible $7k) ÷ $27k]. If you want a clean backdoor Roth with no tax implications on the conversion, you'd need to roll your existing pre-tax IRA funds into a workplace 401(k) if your plan allows it. This would leave only your non-deductible contributions in the IRA, which you could then convert tax-free.

I've been using taxr.ai for figuring out complex tax situations like this, and it's been incredibly helpful for my backdoor Roth questions. After struggling with the pro-rata calculations myself last year and getting conflicting advice from friends, I found taxr.ai (https://taxr.ai) and it made the whole process much clearer. Their tool analyzed my specific situation with multiple IRAs and helped me understand exactly what I needed to report on Form 8606. It even showed me how different conversion strategies would affect my tax bill. What I really liked is that they explained the pro-rata rule in terms I could actually understand, unlike the confusing IRS documents.

•Does it actually help with the calculations? I've been trying to figure out my own backdoor situation and kept getting different numbers every time I try to calculate the taxable portion.

•I'm pretty skeptical of these tax tools. Does it actually give tax advice or just general info? I've been burned before by services that just regurgitate IRS publications without actually helping with my specific scenario.

•It actually does the calculations based on your specific numbers. You input your IRA balances, contribution amounts, and it shows you exactly how much would be taxable in different scenarios. Really helpful when you're trying to optimize your conversion strategy. The advice is tailored to your situation, not generic info. What impressed me was how it explained which parts of my conversion would be taxable and why, then showed how that would change if I rolled some funds to my 401k first. It even creates a personalized report you can reference when filling out your tax forms.

Just wanted to update after trying taxr.ai for my backdoor Roth situation. I was totally confused about how much of my conversion would be taxable with multiple IRAs and some old rollovers from previous jobs. The tool analyzed all my accounts and clearly showed me that I'd be paying taxes on about 86% of any conversion due to the pro-rata rule. But then it suggested I roll my pre-tax IRA funds into my current employer's 401k plan first (which I didn't even know was possible). After doing that, I was able to do a completely tax-free backdoor Roth conversion of my new contributions! Saved me from a pretty expensive tax mistake and the documentation it provided made filling out Form 8606 way easier. Thanks for recommending it!

If you're struggling to get answers from the IRS about backdoor Roth conversions or pro-rata calculations, I'd recommend trying Claimyr (https://claimyr.com). I was stuck in an endless loop trying to reach someone at the IRS about my specific backdoor Roth questions for weeks. After three failed attempts and hours on hold, I tried Claimyr and actually got through to an IRS agent in about 15 minutes. They have this system that navigates the IRS phone tree for you and holds your place in line, then calls you back when an agent is available. You can see how it works here: https://youtu.be/_kiP6q8DX5c The IRS agent was able to confirm exactly how I needed to handle my backdoor Roth conversion with existing balances and cleared up my confusion about Form 8606 reporting. Saved me so much time and frustration!

•How does this actually work? Do they have some special connection to the IRS or something? Seems weird that they could get through when regular people can't.

•This sounds like complete BS. Nobody can magically get through to the IRS faster. They're probably just recording your personal tax info or scamming people somehow. I'd be extremely careful about using services like this.

•They don't have any special connection to the IRS - they just use automated technology to dial repeatedly and navigate the phone system for you. Basically it's doing what you'd do manually, but their system keeps trying different IRS numbers and paths until it finds an available agent. The service is legitimate and secure. They don't ask for or record any of your tax information - they just connect the call to you when they reach an agent. I was skeptical too until I tried it. They're actually saving you from having to sit on hold for hours, which is what most people end up doing when trying to reach the IRS directly.

I have to admit I was totally wrong about Claimyr. After dismissing it as a scam, my accountant actually recommended it when I was desperate to get an answer about my backdoor Roth situation before the tax deadline. I tried it as a last resort and was shocked when I got a call back in about 20 minutes with an actual IRS agent on the line. The agent walked me through exactly how to handle my backdoor Roth conversion with pre-existing IRA balances and confirmed the correct way to complete Form 8606. What would have been days of stress and uncertainty was resolved in one phone call. I'm not usually one to admit when I'm wrong, but this service actually delivered exactly what it promised. Definitely worth it when you need answers directly from the IRS.

I did a backdoor Roth last year and learned it's much easier if you don't mix it with existing pre-tax IRAs. What I ended up doing was rolling my traditional IRA into my employer's 401k plan first (check if yours allows this). That way, I started fresh with just the non-deductible contribution, which made the conversion clean with no pro-rata tax complications. One thing to remember - you still need to file Form 8606 to report the non-deductible contribution regardless of when you do the conversion. Also, if there are any gains between when you contribute and when you convert, those gains are taxable.

•Do you know if there's a time limit between making the contribution and doing the conversion? I contributed throughout 2024 but am just now looking to convert in December. Will this cause issues?

•There's no time limit between contribution and conversion, so December is fine for contributions made earlier in 2024. However, the longer you wait, the more likely your investments will generate gains, which would be taxable upon conversion. Ideally, for future backdoor Roth conversions, consider contributing to a non-deductible traditional IRA and converting to Roth immediately before investing the funds. This minimizes taxable gains. Many people who regularly do backdoor Roths make their contribution and conversion on the same day or within a few days to avoid this issue altogether.

Does anyone know if I need to sell my investments in the traditional IRA before converting to Roth? Or can I just transfer the shares directly?

•You can transfer the shares directly! It's called an "in-kind" conversion. No need to sell and rebuy, which is actually better because you don't miss any market movements between selling and rebuying. The value of the shares on the conversion date is what matters for tax purposes.

Madison, I went through this exact same situation last year! The key thing to understand is that you can't just convert the $7,000 you contributed this year due to the pro-rata rule that Julian explained perfectly. Since you have $55k in pre-tax funds plus your $7k contribution (total ~$62k), any conversion will be mostly taxable. If you convert $7,000, roughly $6,113 would be taxable income based on the pro-rata calculation ($55k ÷ $62k × $7,000). My advice: if your employer's 401(k) accepts IRA rollovers, consider rolling your existing $55k pre-tax balance into your 401(k) first. This would leave only your non-deductible $7k contribution in the IRA, which you could then convert to Roth with minimal tax consequences (only on any gains since contribution). Also, don't forget to file Form 8606 to report your non-deductible contribution - this is crucial for establishing your basis. For future years, consider making the non-deductible contribution and converting immediately to minimize gains and keep the process clean.

•This is really helpful advice! I'm in a similar situation with existing pre-tax IRA funds and was wondering about the 401(k) rollover option. Do you know if there are any restrictions on rolling IRA funds into a 401(k)? Like does it have to be from a previous employer's 401(k) originally, or can any traditional IRA funds be rolled in? Also, are there any timing considerations I should be aware of when doing the IRA-to-401(k) rollover before the backdoor Roth conversion?
