What's required for tracking cost basis of investments in IRA, Roth, and 401(k) retirement accounts?

What about if you roll over a 401(k) to an IRA? Does that complicate things at all with tracking basis? And also is there anything special about the self-directed 401(k) question the OP asked about?

Rollovers from a 401(k) to an IRA don't complicate basis tracking as long as you do a direct rollover. The rollover amount becomes part of your IRA balance, but you still don't need to track individual investment basis within either account. Self-directed 401(k)s function the same way for tax purposes. Whether you're picking the investments yourself or using preset options, the IRS still only cares about money going in and coming out of the account, not the performance of individual investments within it. The self-directed aspect just gives you more control over investment choices, not more tax paperwork.

Does it work with multiple types of accounts? I have a traditional 401k from my current job, a Roth IRA I've had for years, and an old 403b from when I worked at a university. Can it handle all those different account types?

I'm a bit skeptical about uploading financial documents to random websites. How secure is this actually? And can it really understand the difference between rollovers, conversions, and regular contributions? That's where I always get confused.

It absolutely works with multiple account types - I used it with a traditional 401(k), Roth IRA, and a SEP IRA from my side business. It can distinguish between all the different retirement vehicles and their specific tax treatments. Their security is actually really good - they use bank-level encryption and don't store your documents after processing. And yes, it accurately identified when I did a rollover versus new contributions, and even flagged a Roth conversion I did a few years ago that I had documentation questions about. The analysis breaks everything down by tax year which was super helpful.

Wait how does this actually work? Do they have some special connection to the IRS or something? I've been trying to reach someone about my retirement account basis issues too but no luck after multiple attempts.

This sounds like BS honestly. Nobody can "skip the line" with the IRS. They're probably just autodialing them repeatedly until they get through and charging you for the privilege. I'll stick with waiting on hold myself, thanks.

They don't have a special connection to the IRS - they use technology to continuously call and navigate the IRS phone tree until they get through to a representative. When an agent answers, they connect you to the call. It's basically outsourcing the frustrating hold time. It's definitely not BS - they're just solving a real problem with the overwhelmed IRS phone system. I was skeptical too until I tried it. I spent weeks trying to get through on my own with no luck, then got connected within 15 minutes using their service. The time I saved was absolutely worth it, especially since the information I got from the IRS agent was exactly what I needed to correctly handle my retirement account basis.

What about if you have company stock in a 401(k)? I've heard there's some special rule called Net Unrealized Appreciation that makes tracking the basis important? Not sure if that's an exception to what you're saying.

That's a great question! Company stock in a 401(k) is indeed a special case. If you have employer stock in your 401(k), you can potentially use the Net Unrealized Appreciation (NUA) strategy when you take a lump-sum distribution. This allows you to pay ordinary income tax only on the cost basis of the company stock, while the appreciation gets taxed at lower capital gains rates when you sell. In this specific scenario, yes, tracking the basis of those company shares becomes very important. It's one of the few exceptions to the general rule about not needing to track individual investment basis in retirement accounts. Good catch!

I got a CP2000 notice (not a full audit) about IRA contributions a few years ago. Had to prove I was eligible for the deduction. They didn't care about individual investments in the account, just that my contributions were properly reported and that I was eligible to make them. Your 401k provider should have records they can provide if you need them - most keep them for at least 7 years.

This is such valuable advice! I had no idea the SSA keeps track of 401(k) deferrals - that's a game changer for anyone with missing records. I'm actually in a similar situation where I switched jobs several times and have gaps in my paperwork from the mid-2010s. One question about the SSA records - do they show both traditional and Roth 401(k) contributions separately, or just the total deferral amount? I had a mix of both types of contributions during some years and I'm wondering if I'll be able to distinguish between them from the SSA data alone. Also, thanks for mentioning that the IRS accepts reasonable reconstructions. That takes a lot of pressure off knowing you don't need perfect records as long as you can show good faith effort. This whole thread has been incredibly reassuring!

Great question about the SSA records! Unfortunately, the SSA earnings record typically shows your total 401(k) deferrals but doesn't break down traditional vs. Roth contributions separately. You'll see the total amount that was deferred from your paycheck, but not the tax treatment breakdown. For distinguishing between traditional and Roth 401(k) contributions, your best bet is still going to be your old W-2s or records from the plan administrator. Your W-2 should show traditional 401(k) contributions in box 12 (codes D, E, F, or G), while Roth 401(k) contributions are included in your taxable wages but shown separately in box 12 (code AA). If you can't locate the W-2s, you might be able to request copies from the IRS using Form 4506-T for a small fee, or sometimes your old employers can provide duplicates. The plan recordkeepers are also usually pretty good about providing historical contribution breakdowns - they're required to maintain these records for quite a while. But honestly, unless you're dealing with basis tracking for non-deductible contributions or planning some complex distribution strategy, the exact traditional vs. Roth split from years past may not be critical for most tax purposes. The main thing is having a reasonable estimate of your total contributions over time.

Great question about the SSA records! Unfortunately, the SSA earnings history typically shows your total 401(k) deferrals as one combined amount - they don't break down traditional vs. Roth contributions separately. You'll see the total deferral amount in the "retirement plan" box on your W-2 history, but not the split between pre-tax and Roth. To reconstruct the traditional vs. Roth breakdown, you'd need to look at your old tax returns or contact the former plan administrators. Your tax returns would show traditional 401(k) contributions as a reduction to your taxable income, while Roth contributions wouldn't appear as a deduction. If you filed electronically, you might be able to get old returns from your tax software provider, or you can request transcripts from the IRS. It's a bit more detective work, but definitely doable! The SSA records at least give you the total contribution amounts to work backwards from.
