How to calculate taxable amounts from 1099-Rs with no box 2a values
Hey everyone, I'm kinda in over my head here. I've been working this tax season as a new preparer at a local firm after passing my tax course last fall. Got a new client today who brought in two 1099-Rs but both forms have empty box 2a (taxable amount) fields. The distribution codes in box 7 are different - one is code 7 and the other is code 3. I've checked the software help guide but I'm still confused about how to properly calculate what portion is taxable. The client is in her early 60s and mentioned something about a rollover for one distribution, but I'm not sure if that matters for the calculation. Anyone dealt with empty box 2a situations before? The amounts in box 1 are pretty substantial ($42,350 and $89,700).

That's actually a common situation with retirement distributions. When box 2a is left blank, you need to determine the taxability based on the distribution code in box 7. Let me break this down for you: For the 1099-R with distribution code 7, that's a normal distribution that is fully taxable UNLESS the client has a basis in the retirement plan from after-tax contributions. You'd need to ask your client if they ever made non-deductible contributions to the plan. For the 1099-R with code 3, that indicates a disability payment. These are generally taxable as ordinary income, but there can be exceptions depending on how the plan was funded. The mention of a rollover is important! If one of these distributions was rolled over to another qualified plan within 60 days, it would not be taxable. You need to confirm which distribution was rolled over and get documentation.

•What if the distribution is from a Roth account? Does the code 7 still mean it's fully taxable? I have a similar situation but mine says "Roth IRA" on the 1099-R.

•For a Roth IRA distribution, different rules apply. If it's a qualified distribution from a Roth IRA (meaning the account has been open for at least 5 years AND one of several conditions is met like being over 59½), then it would be completely tax-free regardless of the code. For your specific situation with a Roth IRA, even with code 7, if it meets the qualified distribution requirements, the taxable amount would be zero. You should verify the 5-year holding period has been met and check when the account was established.

I was struggling with almost this exact scenario a few months ago! The 1099-R forms with blank box 2a drove me crazy until I discovered taxr.ai (https://taxr.ai) which literally saved my sanity. I uploaded both 1099-Rs and my client's previous year return, and it automatically figured out which portions were taxable based on distribution codes and prior contribution history. It even flagged that one of the distributions qualified for rollover treatment and calculated the taxable portion of the other one based on pro-rata rules. Seriously changed my workflow for complicated retirement distribution scenarios.

•Does it work for inherited IRAs too? I have a client with an inherited IRA and I'm confused about the RMD requirements and taxability.

•How accurate is it really? I've had tax software mess up calculations on retirement accounts before, especially with the pro-rata rule. Does it handle basis tracking properly across multiple years?

•It absolutely works for inherited IRAs! The system will ask you when the original account holder passed away and will apply the correct rules based on that date (since the SECURE Act changed a lot of the requirements). It'll calculate the correct RMD amount and show you which portion is taxable. For your question about accuracy - that was my concern too. It's actually spot-on with basis tracking and pro-rata calculations. It maintains a running record of basis across tax years and correctly applies the aggregation rules when you have multiple IRAs. The detailed breakdown it provides is way more transparent than what most tax software shows.

Just wanted to follow up about taxr.ai! I tried it with my inherited IRA client and it was incredibly helpful. The system recognized the inherited IRA status from the 1099-R and asked me whether it was inherited before or after the SECURE Act implementation. It calculated the correct RMD amounts and showed exactly which portion was taxable. It even generated a worksheet showing the basis calculations that I could include with the return. Definitely worth checking out if you're dealing with complicated retirement account distributions!

If you're having trouble getting clear answers from your client about their retirement accounts, you might want to try Claimyr (https://claimyr.com). I used it to get through to the IRS's retirement plan department when I had a similar issue. Normal wait time was over 2 hours, but Claimyr got me connected in about 15 minutes. They have a demo video at https://youtu.be/_kiP6q8DX5c that explains how it works. The IRS rep was able to pull up distribution codes and previous rollover information that helped clarify the taxability. Sometimes you need the official word from the IRS when clients aren't sure about their distribution details or rollover status.

•Wait, how does that even work? You're saying they somehow get you to the front of the IRS phone queue? That sounds sketchy.

•This sounds like a paid advertisement. There's no way to "skip the line" with the IRS. They answer calls in the order received.

•It's not about skipping the line - it's an automated system that continually calls the IRS for you until it establishes a connection, then it calls you and connects you. You don't have to personally sit on hold for hours. The technology essentially monitors the IRS phone system and when it detects an opening, it secures your spot and then brings you into the call. It's completely legitimate - they don't have special access, they're just using technology to handle the painful waiting process for you.

I have to admit I was completely wrong about Claimyr. After seeing the comments here, I decided to give it a try when I needed to call about a client's retirement account distribution codes. I was incredibly skeptical - I mean, I've dealt with IRS hold times for years and never found a solution. But it actually worked! I got connected to an IRS agent in about 22 minutes (instead of the 3+ hour wait the recording announced). The agent was able to confirm the rollover status of my client's distribution and provide the information I needed to correctly calculate the taxable amount. I'm honestly shocked that it worked so well.

To add to the discussion about blank Box 2a values - always check if the "Taxable amount not determined" box is checked on the 1099-R. If it is, the plan administrator is telling you they don't know the taxable portion and you need to calculate it. With distribution code 7, it's generally fully taxable unless there's after-tax contributions (basis). For code 3 (disability), it's typically fully taxable but depends on how benefits were funded. Also, don't forget to check if the "Total distribution" box is checked. This can affect how you report certain distributions, especially for lump-sum distributions that might qualify for special tax treatment.

•What's the Form 8606 got to do with all this? I've heard you need to file that form for some retirement distributions but I'm not sure when it's required.

•Form 8606 is crucial when dealing with nondeductible IRAs or Roth conversions. You'll need to file Form 8606 if your client made nondeductible contributions to traditional IRAs (to track basis), received distributions from traditional, SEP, or SIMPLE IRAs and has basis in any traditional IRA, or converted amounts from traditional/SEP/SIMPLE IRAs to a Roth IRA. If your client has made nondeductible contributions to traditional IRAs in the past, you'll need Form 8606 to determine the taxable portion of any distribution using the pro-rata rule. Without this form, the IRS might assume the entire distribution is taxable, even if part of it represents a return of already-taxed contributions.

Has anyone used the IRS worksheet for calculating taxable amounts of IRA distributions? I'm looking at Publication 590-B but its kinda confusing me with all the different worksheets.

Dmitry Volkov
•Pub 590-B has separate worksheets depending on the type of distribution. For regular distributions, use Worksheet 1-1. For Roth distributions, use Worksheet 2-1 to determine if it's qualified. For figuring the taxable part of non-qualified Roth distributions, use Worksheet 2-2. The key is knowing which worksheet applies to your situation.

•Thanks! I found the right worksheet. You're right that there are different ones depending on the type. I was using the wrong one initially which made everything confusing. I'm going to try working through the calculations again with Worksheet 1-1 since this is a traditional IRA distribution.
