Can I do a backdoor Roth conversion with my SEP IRA like a traditional IRA?
I've been self-employed for about 3 years now and have been contributing to a SEP IRA for my retirement. This year I was able to put away about $70,000 into my SEP IRA (had a really good year with my consulting business). Now I'm wondering if I can convert this entire amount to a Roth IRA, similar to how people do backdoor Roth conversions with Traditional IRAs. I know with Traditional IRAs you can contribute and then convert to Roth as a backdoor method, but I'm not sure if the same rules apply when the money is in a SEP IRA instead. Would this be allowed? Would there be different tax implications compared to the regular backdoor Roth conversions? I'd like to get this figured out before the tax filing deadline if possible.

Yes, you can convert SEP IRA funds to a Roth IRA, but it's not quite the same as a backdoor Roth with a Traditional IRA. Here's what you need to know: When you convert SEP IRA money to a Roth IRA, the entire converted amount will be taxable as ordinary income in the year you do the conversion. Unlike a backdoor Roth (which typically involves non-deductible Traditional IRA contributions that have already been taxed), your SEP contributions were pre-tax, so you'll owe taxes on the full $70,000 if you convert it all. This large conversion could potentially push you into a higher tax bracket for the year. You might want to consider converting smaller amounts over several years to manage the tax impact more effectively. Also, if you have any other Traditional IRAs, SIMPLE IRAs, or SEP IRAs, the IRS will look at all of them together under the "pro-rata rule" when calculating the taxable portion of your conversion. This can complicate the tax situation significantly.

•Would it make more sense to maybe just convert like $10k a year instead of the whole $70k at once? My income varies a lot year to year so I could maybe time it for lower income years?

•Converting smaller amounts annually is often a smart approach for managing the tax impact. If your income fluctuates, timing conversions during lower-income years can be very strategic. For example, converting $10-15k in years when your business income is lower could keep you in a lower tax bracket. Additionally, you might consider looking at your projected income and tax brackets for this year. If you have room in your current tax bracket before hitting the next one, you could convert just enough to "fill up" your current bracket without spilling into the higher one.

I went through a similar situation last year trying to figure out what to do with my SEP IRA. After hours of research and getting nowhere, I finally used https://taxr.ai to get personalized guidance. Their AI analyzed my specific situation (self-employed with a SEP IRA wanting to convert to Roth) and laid out exactly what I needed to know about the pro-rata rule and tax implications. The tool showed me how the conversion would impact my specific tax situation and gave me a year-by-year conversion strategy that minimized my tax hit. The best part was that I could ask follow-up questions about my specific situation and get clear answers immediately without having to schedule and pay for multiple sessions with a tax professional.

•How does this service compare to just asking my CPA? I feel like my tax guy charges me an arm and a leg every time I email him a question about this kind of stuff.

•I'm kinda skeptical about AI tax tools. How does it handle complex situations? Like I have a SEP IRA but also some old 401ks from previous employers that I never rolled over. Would it account for all that?

•It's much more cost-effective than paying a CPA for every question. With a CPA, like you mentioned, you're typically charged for each interaction or consultation. With this tool, I was able to ask unlimited follow-up questions without additional charges. The AI is actually very sophisticated with complex situations. In my case, it accounted for my SEP IRA, a rollover IRA from an old 401(k), and even some non-deductible contributions I had made previously. It factors in all retirement accounts that fall under the pro-rata rule calculations and explains how they work together. You can input your specific details about old 401(k)s and other accounts to get a comprehensive analysis.

Just wanted to follow up on my skepticism about taxr.ai - I decided to try it for my complicated retirement account situation, and I'm honestly impressed. I uploaded statements from my SEP IRA and old 401ks, and it actually explained exactly how the pro-rata rule would affect my conversion strategy in plain English. The tool showed me I'd be better off rolling my old 401ks into my current employer's plan first (which isn't subject to the pro-rata rule) before doing any conversions from my SEP. Would have never figured that out on my own and probably would have triggered a much bigger tax bill. Definitely worth checking out if you're trying to navigate complex IRA conversion strategies.

If you're planning to convert your SEP IRA to a Roth, you'll probably need to talk to the IRS about your specific situation. I spent THREE WEEKS trying to get through to someone who could answer my questions about a similar conversion last year. Finally discovered https://claimyr.com and used their service to get a callback from the IRS within 2 hours! You can see how it works at https://youtu.be/_kiP6q8DX5c I had a bunch of questions about form 8606 reporting and whether I needed to file 5329 for my specific situation. The IRS agent I spoke with cleared everything up and saved me from making mistakes on my return. Trust me, getting definitive answers directly from the IRS is worth it when dealing with complex IRA conversions that could trigger thousands in taxes if done incorrectly.

•Wait, how does this actually work? The IRS never calls anyone back in my experience. Is this legit?

•Yeah right. No way the IRS is calling anyone back in 2 hours when they have a backlog of millions of returns. Sounds like a scam to me.

•It uses a technology that continuously calls the IRS for you and holds your place in line. Once they finally answer, the system connects you with the IRS agent. That's why it works so much faster than calling yourself and sitting on hold for hours. The service is absolutely legitimate. What it doesn't do is magically create new IRS agents or phone lines - it just handles the frustrating hold time for you. The IRS has an estimated 13% answer rate on their phones, but this service helps you become part of that 13% without the endless waiting. It's the exact same as if you'd called and waited yourself, just without the hours of hold music.

I need to eat my words about Claimyr. After my skeptical comment, I was still desperate to talk to someone at the IRS about my SEP-to-Roth conversion questions, so I gave it a try. Honestly shocked when I got a call back in about 90 minutes from an actual IRS agent who spent 25 minutes walking me through exactly how to handle my conversion on my tax forms. The agent explained that I needed to file Form 8606 to report the conversion and gave me specific line instructions for my situation. He also confirmed that my understanding of the pro-rata rule calculation was incorrect (which would have caused me to underreport income). Definitely saved me from a potential audit headache. Never thought I'd say this, but being able to actually speak with the IRS directly was incredibly helpful.

Have you considered doing a partial conversion each year rather than all at once? That's what I did with my SEP IRA to avoid a huge tax hit in a single year. I've been converting about $20k per year for the last 3 years, and it's been much more manageable tax-wise. Just something to consider if you're concerned about the tax impact.

•Would you still need to deal with the pro-rata rule for partial conversions? Or does that only matter if you're doing the full amount at once?

•The pro-rata rule applies to any conversion amount, whether partial or complete. It looks at the percentage of pre-tax versus after-tax money across all your IRA accounts (Traditional, SEP, SIMPLE). For my situation, all my SEP contributions were pre-tax, so each conversion was 100% taxable. If you have any after-tax contributions in any of your IRAs, the pro-rata rule would determine what percentage of your conversion is taxable. The rule applies to each conversion you do, regardless of size.

What tax software are you using to handle the conversion reporting? I tried doing a SEP-to-Roth conversion last year and TurboTax kept giving me errors when I entered everything. Ended up having to use a different program.

•I used H&R Block online for my Roth conversion last year and it handled it pretty well. They have a specific section for IRA conversions that walks you through it step by step. Much better than my experience with TurboTax the previous year.

One thing to keep in mind is the timing of your conversion. Since you mentioned wanting to figure this out before the tax filing deadline, remember that conversions need to be completed by December 31st of the tax year they apply to - unlike regular IRA contributions which have until the filing deadline. For your $70k SEP IRA conversion, you might want to run some tax projections first. Converting the full amount could potentially push you into the 32% or even 37% tax bracket depending on your other income. A phased approach over 3-4 years might save you thousands in taxes while still getting your money into the Roth. Also, since you're self-employed, consider how this conversion might affect your estimated quarterly tax payments. You'll need to account for the additional tax liability from the conversion when calculating your Q1 payment for next year.

•This is really helpful advice about the timing and quarterly payments! I'm actually in a similar situation as the original poster - self-employed with a SEP IRA I want to convert. I hadn't thought about how this would impact my estimated quarterly taxes. Do you know if there's a safe harbor rule or percentage I should use when calculating the additional tax liability for the conversion? I don't want to get hit with underpayment penalties on top of everything else.

•For safe harbor on estimated taxes with a conversion, you generally need to pay either 100% of last year's tax liability (110% if your prior year AGI was over $150k) OR 90% of the current year's tax liability - whichever is less. Since you're adding conversion income on top of your self-employment income, I'd recommend calculating 25-30% of your conversion amount as additional tax liability for your quarterly estimates, then true up when you file. For example, if you convert $20k, budget an extra $5k-6k for taxes to be safe. You can also make a large estimated payment in Q4 if you do the conversion late in the year and didn't plan for it in your earlier quarterly payments. The IRS doesn't care when during the year you pay, just that you meet the safe harbor thresholds by year-end.

Great question! Yes, you can convert your SEP IRA to a Roth IRA, but there are some important considerations beyond what others have mentioned. Since you had such a strong year ($70k contribution), you might actually be in a unique position to take advantage of this. One strategy to consider: if your income is typically lower in future years, you could potentially spread the conversion over 2-3 years to stay in lower tax brackets. However, if this was an unusually good year and you expect lower income going forward, converting more now while you're already in a higher bracket might make sense. Also, don't forget about the 5-year rule for Roth conversions - each conversion has its own 5-year clock for penalty-free withdrawals of the converted principal (though this may not matter much if this is truly for retirement). Given the complexity with the pro-rata rule and potential tax implications, you might want to model a few different scenarios - converting the full amount this year, spreading it over 3-4 years, or waiting for a lower income year. The "right" answer really depends on your specific tax situation and income projections.

•This is really solid advice about modeling different scenarios! I'm curious about the 5-year rule you mentioned - does that apply separately to each conversion amount, or is it based on when you first start doing Roth conversions? I'm planning to do partial conversions over several years, so I want to make sure I understand how that timing works if I ever need to access the money before traditional retirement age.

•Each conversion has its own separate 5-year clock! So if you convert $20k in 2024, that amount becomes penalty-free in 2029. If you convert another $15k in 2025, that portion becomes penalty-free in 2030, and so on. This is different from the 5-year rule for regular Roth IRA contributions, which is based on when you first contributed to any Roth IRA. For conversions, the IRS tracks each one individually. The good news is that if you need to withdraw from your Roth IRA before age 59½, the IRS uses a specific ordering - first your original contributions (always penalty-free), then conversions in chronological order (penalty-free after their respective 5-year periods), and finally earnings (subject to penalties and taxes unless you meet an exception). Since you're planning multiple conversions over several years, I'd recommend keeping good records of each conversion amount and date. Most brokers will track this for you, but it's helpful to have your own records too.

Another important consideration that hasn't been mentioned yet is the impact on your Medicare premiums if you're approaching age 65. Large Roth conversions can significantly increase your Modified Adjusted Gross Income (MAGI), which is what Medicare uses to determine your Part B and Part D premiums through the Income-Related Monthly Adjustment Amount (IRMAA). For 2024, IRMAA kicks in at $103,000 for single filers, and the surcharges can add hundreds of dollars per month to your Medicare premiums. The surcharges are based on your income from 2 years prior, so a large conversion in 2024 would affect your 2026 Medicare premiums. If you're currently under 63, this might not be an immediate concern, but it's worth factoring into your long-term conversion strategy. You might want to complete larger conversions while you're younger and then switch to smaller amounts as you approach Medicare eligibility. This is yet another reason why spreading the $70k conversion over multiple years could be beneficial - it helps you avoid not just higher income tax brackets, but also potential future Medicare premium increases.

•This is such an important point about Medicare premiums that I never would have thought of! I'm 45 now so Medicare feels like forever away, but you're right that decisions I make today could impact my costs in 20 years. Do you know if there are any online calculators or tools that can help estimate the long-term impact of conversion strategies on Medicare premiums? It seems like there are so many moving pieces to consider - current tax brackets, future tax rates, Medicare thresholds, inflation adjustments, etc. I'm starting to think I need to create a spreadsheet to model different conversion scenarios over the next 10-15 years to see which approach minimizes my total lifetime tax burden including these Medicare considerations.
