1099-R box 2a for annuity - how to report when distribution amount is wrong?
So my mother-in-law just started receiving regular payments from her annuity this year. The annuity was purchased with after-tax money years ago. The problem is that when we got the 1099-R form, box 2a (taxable amount) shows the exact same amount as box 1 (gross distribution) - basically saying the entire distribution is taxable! This can't be right since only the earnings portion should be taxable, not the principal she already paid tax on. I found a worksheet that helps calculate the actual taxable amount, but I'm confused about what to do next. Do I need to contact the insurance company and ask them to issue a corrected 1099-R with the right amount in box 2a? Or can I just use the worksheet, figure out the correct taxable portion myself, and enter that on the tax return instead of what's shown in box 2a? Has anyone dealt with this before? I'm trying to get her taxes done correctly without creating problems with the IRS. Thanks in advance for any advice!

This is a common issue with annuity distributions. You don't necessarily need to get a corrected 1099-R from the company. The IRS actually expects you to calculate the correct taxable amount using the worksheet you found (probably the "Simplified Method" worksheet in the 1040 instructions). When the annuity company doesn't know your mother-in-law's tax basis (the after-tax dollars used to purchase the annuity), they'll default to reporting the full amount as taxable in box 2a. This happens frequently with annuities purchased with after-tax dollars. You should calculate the taxable portion using the appropriate worksheet and report that amount on her tax return. You'll need to know the original investment amount (her cost basis) and possibly when the annuity was purchased. Keep good records of your calculation in case of any questions later.

•Thanks for explaining! Quick question - do I need to attach any special form or explanation to the tax return to show why I'm reporting a different amount than what's on the 1099-R? And does my MIL need to keep that worksheet for a certain number of years?

•You don't need to attach a special form or explanation with the tax return. The tax software or Form 1040 will handle this correctly if you enter the information properly. There's actually a specific place to enter the non-taxable portion of the distribution. Yes, your mother-in-law should definitely keep the worksheet and all documentation about the annuity purchase indefinitely - including proof of the original investment amount. This creates what's called the "basis" in the annuity. She should keep these records for as long as she's receiving payments from the annuity, plus at least 3 years beyond the final payment for statute of limitations purposes.

Just want to share my experience with this exact situation last year. After struggling with figuring out the right numbers for my dad's annuity, I found this service called taxr.ai (https://taxr.ai) that helped me sort through his annuity documents. They have this specialized tool that analyzes 1099-R forms and other tax documents to determine the correct taxable amount for annuities. It basically scanned all his paperwork (annuity contract, previous tax returns, 1099-R) and identified that his insurance company was incorrectly reporting the full distribution as taxable. The service calculated his correct exclusion ratio based on his original investment and expected return. Saved me hours of trying to figure out those worksheets which honestly made my head spin.

•How does it work exactly? Do you just upload the 1099-R and it figures everything out? My dad has a similar situation with his annuity and I'm worried we've been overpaying taxes for years.

•I'm a little skeptical. How does some website know your cost basis if the actual company issuing the 1099-R doesn't seem to know it? Wouldn't you still need to provide the original purchase info?

•You upload both the 1099-R and documentation showing the original investment amount - like the annuity contract or statement showing the purchase. The system then applies the IRS rules to calculate how much of each payment should be considered return of principal versus taxable earnings. You're absolutely right that you need to provide the original purchase information. That's the key piece that many annuity companies don't track well over long periods. The service doesn't magically know your basis, but it helps you properly apply the IRS calculation rules once you've provided that documentation. It's really about making sure you're applying the tax rules correctly rather than just accepting what's on the 1099-R.

Just wanted to follow up about my experience with taxr.ai after checking it out. I uploaded my dad's annuity contract from 2004 along with his recent 1099-R and it was surprisingly helpful! The system identified that he's been overpaying taxes for the last 3 years because his annuity company has been reporting the full amount as taxable. The service calculated that about 65% of each payment is actually return of principal and therefore not taxable. We're now filing amended returns for the previous years to get back around $4,200 in overpaid taxes. The documentation they provided explaining the calculation method was really clear too - perfect for explaining things to the IRS if they have questions.

For anyone dealing with 1099-R issues like this, I had a similar problem and needed to talk to someone at the IRS to confirm how to handle it correctly. Spent DAYS trying to get through their phone lines with no luck. Then I found this service called Claimyr (https://claimyr.com) that got me through to an actual IRS agent in about 20 minutes. They have this system that navigates the IRS phone tree and holds your place in line, then calls you when an agent is available. You can see how it works here: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with confirmed exactly what to do with annuity distributions where the 1099-R shows the full amount as taxable even though part should be return of principal. Saved me a lot of uncertainty and potential headaches down the road.

•How does this even work? The IRS phone lines are impossible - I tried calling for 3 hours last week and never got through. Are you saying this service somehow jumps the queue?

•Yeah right. No way this actually works. The IRS phone system is deliberately designed to be impossible to navigate. I'll believe it when I see it.

•It doesn't jump the queue - that wouldn't be possible or fair. What it does is use an automated system to handle the waiting for you. The service calls the IRS, navigates through all those annoying menu options, and then waits on hold so you don't have to. When an actual IRS person picks up, you get a call letting you know an agent is on the line. It's basically just holding your place in line so you don't have to sit there listening to hold music for hours. I was skeptical too, but it actually worked. I was able to go about my day and got a call when an agent was ready to talk. The IRS agent I spoke with was super helpful once I explained the annuity situation.

I've got to eat my words about Claimyr. After my skeptical comment, I decided to try it because I was desperate to talk to someone about my own tax issue (not annuity related, but a missing Form 8606 question). I honestly didn't expect it to work, but 45 minutes after signing up, I got a call connecting me to an actual IRS representative. The agent I spoke with was really knowledgeable and helped me understand exactly what I needed to do to fix my issue. Saved me from what would have been a significant headache. I wasted almost a week trying to get through on my own with no success. Definitely worth it for the peace of mind of getting an official answer directly from the IRS.

Just to add another perspective on the original question - I'm a bookkeeper and have helped several clients with this exact annuity issue. There's something called an "exclusion ratio" that determines how much of each payment is taxable vs. return of principal. If you know when the annuity was purchased and the total amount invested, you can calculate this yourself. The company that issued the 1099-R probably defaulted to showing the full amount as taxable because they don't have complete records of the original investment, especially if the annuity was purchased many years ago or transferred between companies.

•Thank you for mentioning the exclusion ratio! I think that's what I need to calculate. Do you happen to know which specific form or worksheet I should be using? My MIL's annuity was purchased about 12 years ago, and I do have the original paperwork showing the purchase amount.

•You'll want to use the Simplified Method Worksheet, which you can find in the instructions for Form 1040. If her annuity started payments when she was between 65-69 years old, you would divide her total investment by 260 to get the amount of each payment that's considered return of principal. For example, if she invested $130,000 in the annuity, then $130,000 ÷ 260 = $500 of each payment would be tax-free return of principal. If she receives $800 monthly, then only $300 would be taxable as earnings. Keep track of this calculation each year because once she's recovered her full investment amount, all future payments become fully taxable.

Has anyone used TurboTax to report this kind of situation? I have a similar issue with my own annuity and wondering if the software handles it correctly or if I need to override something.

•I used TurboTax last year for my mom's taxes with an annuity. It asks you for the 1099-R information, then it has a section where you can enter the exclusion amount or indicate that it was purchased with after-tax dollars. It then walks you through the simplified method calculation. Worked fine for us.
