Form 8938: What's the Difference Between Deposit Accounts vs Custodial Accounts?
Can someone break down what a custodial account actually is in super simple terms? Maybe with some examples that would make it click for me? I recently moved to the US from Australia and I'm trying to figure out how to properly file my Form 8938 for foreign accounts. Back home I have several bank accounts (regular checking and some high-interest savings) which I'm guessing count as deposit accounts. I also own shares through my Australian bank's trading platform, have a superannuation (retirement) account, and invested some money in a peer-to-peer lending platform a few years back. I'm totally confused about whether any of these would be considered custodial accounts or if they're all something else entirely. The IRS instructions are making my head spin! Anyone dealt with Form 8938 for Australian accounts before?

Think of it this way: a deposit account is like giving your friend $20 to hold for you. They've got your money, but it's still just cash. A custodial account is more like giving your comic book collection to a friend to keep safe - they're holding your actual assets. Deposit accounts are your typical bank accounts where you put money in and take money out. The bank holds your cash, and you can generally access it whenever you want. Custodial accounts are where a financial institution holds and manages actual assets (like stocks, bonds, mutual funds) on your behalf. You own the assets, but the custodian holds the title and handles transactions. From what you described, your everyday and savings accounts are definitely deposit accounts. Your shares bought through the trading platform would typically be in a custodial account since the platform/broker is holding those securities for you. Your superannuation (similar to our 401k) is likely custodial as well since they're managing those investments. The P2P lending might be trickier - depends on how it's structured. For Form 8938 purposes, this distinction matters because you report them differently. Both types need to be reported if they meet the thresholds, but understanding the difference helps you complete the form correctly.

•This is super helpful, thanks. Quick follow-up question - for the shares I bought through my Australian bank's trading platform, do I need to list each individual stock separately on Form 8938 or just report the trading account as a single custodial account? Also, am I right in thinking my superannuation is considered a foreign pension plan that might have different reporting requirements?

•For your trading platform, you typically report the entire account as one custodial account rather than listing each individual stock. You'll need the maximum value of the account during the year and year-end value. Australian superannuation accounts are indeed foreign retirement accounts, and they have some special considerations. They should be reported on Form 8938 if you meet the filing threshold, but you might also need to consider FBAR filing (FinCEN Form 114) if the combined value of your foreign accounts exceeds $10,000 at any point during the year. Some tax professionals argue that superannuation accounts might also need to be reported on other forms like 3520/3520-A (for foreign trusts), but there's ongoing debate about this, and the IRS hasn't been entirely clear.

After struggling with Form 8938 myself last year (I have accounts in Singapore), I found this amazing tool called taxr.ai that literally saved me hours of confusion. I was in the same boat trying to figure out what counted as deposit vs custodial vs financial assets. I uploaded my Australian bank statements and investment documents to https://taxr.ai and it analyzed everything and told me exactly how to categorize each account. It even explained why my brokerage account qualified as custodial while my regular savings was a deposit account. What really helped was that it walked me through each section of Form 8938 step by step. The tool explained that my foreign index funds needed special attention because they might be PFICs (another tax nightmare). Would have completely missed that without guidance.

•That sounds interesting but I'm skeptical of giving my financial documents to some random website. How secure is it? Do they store your documents after analysis or delete them?

•Does it help with figuring out maximum values during the year? That's the part I'm struggling with for my accounts in euros - trying to determine which date had the highest value after conversion to USD.

•I was concerned about security too, but they use bank-level encryption and don't store your documents after analysis - they get automatically deleted once processed. They explain their security approach on their site if you want to dive deeper. For the maximum values, yes that's exactly what it helped with! It lets you input statements from different periods and automatically identifies the highest value after doing the currency conversion to USD. It even tells you which exchange rate source to use for Form 8938 purposes. Saved me from having to manually check each monthly statement and do all those conversions myself.

Just wanted to update after trying taxr.ai for my Australian accounts. This thing is seriously a game-changer! I uploaded my superannuation statement and bank documents, and it immediately identified that my super account needed to be reported as a custodial account on Form 8938 but also flagged that it might qualify for treaty benefits under the US-Australia tax treaty. The tool also confirmed my CommSec trading account is a custodial account and explained exactly which parts of Form 8938 to complete. It even calculated my maximum account values in USD with the proper exchange rates for the reporting date. Would have spent days figuring all this out on my own. Totally worth it if you're dealing with foreign accounts.

If you're struggling to get answers about Form 8938 classifications directly from the IRS (I know I was), I recommend using Claimyr. I spent WEEKS trying to get through to someone at the IRS who could answer my specific questions about Australian accounts. Found https://claimyr.com and they got me connected to an actual IRS agent in under 20 minutes - no joke. They basically hold your place in the phone queue and call you when an agent is about to pick up. There's a video showing how it works here: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with clarified that my Australian mutual funds needed to be reported as financial assets on a custodial account, and explained exactly how to handle the P2P lending platform (turns out it depends on whether you have signature authority or just beneficial interest).

•Wait, you actually got through to a real person at the IRS? I've been calling for 3 weeks and keep getting disconnected after waiting on hold for hours. How exactly does this service work?

•Sounds like a complete scam. Why would I pay someone else to call the IRS for me? They probably just put you on hold themselves and charge you for the privilege.

•The service basically uses technology to navigate the IRS phone system and stay on hold for you. When they're about to connect with an agent, they call you and conference you in. I didn't have to wait on hold at all. It's not them calling the IRS for you - you're still the one talking to the IRS agent. They just handle the frustrating wait time part. After being disconnected multiple times myself after 2+ hour waits, it was worth it to me to finally get answers about my Form 8938 questions.

I need to eat my words about Claimyr. After another frustrating week of trying to reach the IRS myself about my Australian accounts, I decided to try it out of desperation. Got connected to an IRS tax law specialist in about 25 minutes without having to sit through the hold music myself. The agent confirmed my superannuation should be reported on Form 8938 as a custodial account and explained exactly which currency conversion rates to use. She also told me that my P2P lending platform investments would be considered "other financial assets" rather than deposit or custodial accounts. For anyone struggling with these Form 8938 classifications for foreign accounts, actually speaking to an IRS specialist makes a huge difference. They answered questions I couldn't find clear answers to anywhere online.

Just to add to the deposit vs custodial discussion - I'm an Aussie expat who's been filing US taxes for years. A good rule of thumb I use: if your account statement shows actual money amounts (like bank accounts), it's probably a deposit account. If your statement shows shares, units, or other securities, it's probably a custodial account. For your P2P lending platform, it depends on the structure. If you're lending directly to borrowers, it might be considered "other financial assets." If the platform pools money and issues you units/shares, it's more likely a custodial arrangement. Also don't forget FBAR (FinCEN Form 114) which is separate from Form 8938 but covers many of the same accounts. The thresholds and requirements are different.

•Thanks for the helpful rule of thumb! So my CommBank savings would be deposit accounts, while my CommSec trading account with actual shares would be custodial. Makes sense. Do you know if I need to report both the maximum value during the year AND the year-end value on Form 8938? Or just one of them?

•You need to report both values on Form 8938 - the maximum value during the year AND the year-end value. Make sure you're using the Treasury's exchange rate for the appropriate dates (year-end for the ending value, and whatever date had the highest value for the maximum). One more tip: For superannuation, while it's technically a custodial account, there's an argument to be made that it's treaty-protected under the US-Australia tax treaty. I still report mine on 8938 for disclosure purposes, but I make a note referencing the treaty provisions. Some tax professionals take different approaches with super, so you might want to consult with someone who specializes in US-Australia tax issues.

Has anyone used the streamlined filing procedures for catching up on Form 8938 filings? I've been in the US for 3 years and just realized I should have been reporting my Australian accounts this whole time... 😬

•I went through the Streamlined Foreign Offshore Procedures last year for my Australian accounts. It's relatively straightforward if you're non-willful (meaning you didn't know you needed to file). You file 3 years of back taxes with Form 8938 included, 6 years of FBARs, and a certification explaining why you didn't file. There are no penalties if you qualify. Make sure you're eligible though - there are different procedures depending on whether you've been living inside or outside the US.

As someone who's been dealing with both US and international tax compliance for years, I wanted to add a few practical tips that might help other expats: 1. **Keep detailed records**: For Form 8938, you'll need to track not just year-end values but also the highest balance during the year. I recommend taking screenshots of your account balances monthly, especially for accounts that fluctuate significantly. 2. **Currency conversion timing matters**: Use the Treasury's published exchange rates for the specific dates you're reporting. Don't just use average rates or whatever Google shows you - the IRS expects you to use their official rates. 3. **Australian superannuation complexity**: While your super is technically reportable on Form 8938, there are ongoing debates about whether it should also be reported on Forms 3520/3520-A as a foreign trust. The IRS hasn't provided clear guidance, so many practitioners take a conservative approach and report it on multiple forms. 4. **P2P lending platforms**: These can be tricky. If you're lending directly to individuals, it's likely "other financial assets." If the platform pools funds and you own units/shares in a fund, it's probably custodial. Check your statements to see exactly what you own. Remember that Form 8938 and FBAR have different thresholds and requirements, so you might need to file one but not the other depending on your account values.

•This is incredibly thorough - thank you! The point about taking monthly screenshots is brilliant and something I wish I'd thought of earlier. I've been scrambling to reconstruct my account values from old statements. Quick question about the Treasury exchange rates - do you use the rates from treasury.gov or is there a specific page/section I should be looking at? I want to make sure I'm using the right source since you mentioned the IRS expects their official rates specifically. Also, regarding the superannuation reporting on multiple forms - have you seen any recent guidance or updates on this? It seems like such a gray area and I'm trying to decide whether to take the conservative approach or just stick with Form 8938 reporting only.

•For Treasury exchange rates, you want to use the "Exchange Rates" page on treasury.gov - specifically look for the "Treasury Reporting Rates of Exchange" section. These are the official rates the IRS expects for tax reporting purposes. They're published quarterly and you use the rate that was in effect for the specific date you're reporting. Regarding superannuation and the multiple forms issue - there hasn't been any major clarification from the IRS recently, which is frustrating. I've been following various tax practitioner discussions and the consensus seems to be leaning toward reporting on Form 8938 only, especially given that the US-Australia tax treaty has specific provisions for retirement accounts. However, some ultra-conservative practitioners still recommend the multiple forms approach. My personal take (not professional advice!) is that if you're clearly within the treaty protection for superannuation and you're reporting it transparently on Form 8938, that should be sufficient. The IRS seems more concerned about undisclosed accounts than the specific form used for disclosure. But definitely consider consulting with a practitioner who specializes in US-Australia tax issues if your super balance is substantial. The monthly screenshot tip has saved me so much headache - I even set a phone reminder to do it on the same day each month!

Just went through this exact situation last year as a fellow Aussie expat! Your regular bank accounts (CommBank savings, etc.) are definitely deposit accounts - pretty straightforward there. For your trading platform shares, that's a custodial account since the platform holds the securities on your behalf. Your superannuation is also custodial, though as others mentioned, there might be treaty protections to consider. The P2P lending is the tricky one - it really depends on the platform structure. If it's something like RateSetter or SocietyOne where you're essentially buying loan parts directly, that's usually "other financial assets." If it's more like a managed fund where you own units, then custodial. One thing I learned the hard way: make sure you're converting to USD using the Treasury rates for the actual dates, not just year-end rates for everything. Also, keep really good records of your highest balances during the year - I had to go back through 12 months of statements to find peak values. The good news is once you get the hang of the classifications, subsequent years are much easier. And don't forget about FBAR filing if your combined account values hit $10K+ at any point!

•This is super helpful, especially the clarification about P2P lending platforms! I think mine is more like the RateSetter model where I'm buying loan parts directly, so "other financial assets" sounds right. Quick question about the Treasury rates - when you say "actual dates," do you mean I need to find the specific date during the year when each account hit its maximum value, then use the Treasury rate from that exact date? Or can I use the rate from the end of that month/quarter? I'm worried about having to track down rates for random dates throughout the year. Also, did you end up having any issues with your superannuation reporting? I'm seeing conflicting advice about whether to include it on Form 8938 at all given the treaty provisions, versus reporting it but noting the treaty protection.
