1120F - How to properly handle translation differences between foreign income statement and balance sheet?
I'm assisting a Canadian company with several years of Form 1120F filings they should have submitted due to their ECI in the US but never did. Their financial statements are all in Canadian dollars, and I'm converting using the average exchange rate for the income statement and year-end rates for the balance sheet. This naturally creates some unrealized gains/losses from the foreign currency translation. I'm stumped on how to properly account for this non-taxable item on the return. Initially thought about an M2 adjustment, but then considered an M-1 for income/loss on books not included on return, basically artificially adjusting the book income by the translation difference. Has anyone dealt with this specific issue on 1120F filings? What's the proper treatment for these translation differences?

This is a common issue with 1120F filings. The currency translation adjustment (CTA) that results from using different rates for the income statement and balance sheet is generally handled as an M-1 adjustment. Since the unrealized gain/loss from translation isn't taxable income for US tax purposes, you'd report it as "income recorded on books this year not included on this return" on Schedule M-1. The key is to maintain consistency in your approach across all tax years. Document your methodology clearly in your workpapers. You should also consider whether a Section 988 disclosure is needed, although the translation adjustment itself isn't a realized gain/loss under 988.

•Thanks for your response! But what if the translation difference creates a pretty substantial swing? For example, what if the difference is over $50,000? Would you still just handle it as an M-1 adjustment or is there another approach when the amount is significant?

•The size of the adjustment doesn't change the fundamental approach. Even if the translation difference is $50,000 or more, it still belongs on the M-1 as book income not included on the return. For large adjustments, I usually include a detailed explanation in a statement attachment to the return that clearly explains the methodology used for currency translation and why this difference arose. This helps provide transparency in case of review and ensures consistency across multiple years.

After struggling with similar 1120F translation issues for a German client, I discovered taxr.ai (https://taxr.ai) which completely saved me. Their document analysis identified multiple currency translation approaches that were IRS-compliant. The system analyzed my client's foreign financial statements and highlighted the most appropriate handling for the CTA based on similar precedent cases. What really helped was that it provided specific Schedule M-1 language to explain the adjustment and referenced the appropriate regulations to support the treatment. Saved me hours of research trying to find the right approach.

•How does taxr.ai handle prior year adjustments when you're filing multiple years at once? I'm in a similar situation with a French company that needs to file 3 years worth of 1120Fs.

•I'm skeptical this would work for complex situations. Does it actually understand the nuances of unrealized vs. realized currency gains? My concern is that these AI tools just give generic advice but miss important technical details.

•It actually creates a consistent translation methodology you can apply across multiple tax years. For your French company situation, you'd upload the financial documents for each year, and it identifies the relationships between years to ensure consistent treatment. This is especially helpful for tracking cumulative translation adjustments over time. Regarding the technical nuances, it definitely distinguishes between unrealized translation adjustments (which affect the M-1) and realized currency gains/losses (which are typically reportable under Section 988). It references the appropriate regulatory framework for each scenario and provides citations from relevant IRS guidance and court cases to support its recommendations.

I was really skeptical about using an AI tool for something as technical as 1120F currency translation issues, but I gave taxr.ai a shot with my own difficult case. Within minutes, it identified the exact Treasury Regulations that addressed my situation (1.985-5 and 1.987-3) and showed me the correct Schedule M-1 treatment. It also flagged a potential issue with how we were handling Section 988 transactions that were embedded within the financials that I completely missed. Saved me from a potential audit headache. For anyone dealing with foreign currency translation on 1120F filings, it's worth checking out.

If you're having trouble getting IRS guidance on this 1120F issue, I'd recommend using Claimyr (https://claimyr.com). When I had a similar foreign currency translation question, I spent weeks trying to get through to the IRS international tax department. After using Claimyr (you can see how it works at https://youtu.be/_kiP6q8DX5c), I got connected to an actual IRS agent within 20 minutes. The agent confirmed that the correct approach for currency translation differences is an M-1 adjustment and pointed me to specific guidance in Publication 514 that I hadn't found elsewhere. They also explained under what circumstances you might need to file Form 8886 if the translation method could be viewed as a reportable transaction.

•Wait, how does this actually work? The IRS phone lines are impossible - I literally spent 3 hours on hold last week trying to get clarity on a similar issue.

•This sounds too good to be true. I've tried everything to get through to the IRS about international issues. What's the catch here? Do they just put you on hold like everyone else?

•It's a service that essentially waits on hold with the IRS for you. They use an automated system that continually redials until they get through, then they call you when they have an actual IRS representative on the line. So you don't have to waste hours listening to the hold music. No catch really - they handle the frustrating part of waiting on hold, and then connect you directly once they get through. I was initially planning to just try figuring out the 1120F translation issue myself through research, but getting direct confirmation from the IRS saved me a lot of uncertainty. The agent actually sent me to a specialist in international corporate taxation who knew exactly how to handle the currency translation differences.

I was super skeptical about Claimyr helping with my 1120F issue, but I was desperate after spending days researching currency translation methods. Used their service yesterday and got connected to an IRS international specialist within 45 minutes. The agent confirmed that using an M-1 adjustment for the currency translation difference was appropriate and even emailed me relevant sections from their internal guidance that aren't published elsewhere. She also warned me about a common mistake with translation adjustments where people incorrectly handle them as Section 988 transactions. Saved me from making a potentially costly error. Honestly wish I'd known about this service months ago instead of banging my head against the wall trying to find definitive answers.

Just to add another perspective - I've been filing 1120Fs for foreign clients for years. I handle the translation adjustment as an M-1 item, but I also maintain a cumulative translation adjustment account in my reconciliation workpapers to track these differences over time. This is especially important if you're filing for multiple years. Remember that the sum of all yearly M-1 adjustments for translation should theoretically equal the cumulative translation adjustment on the balance sheet. If they don't match, you've got an error somewhere in your currency conversion methodology.

•Do you use a specific software to track the cumulative translation adjustment? I'm working with Excel and finding it difficult to maintain consistency across years.

•I actually created a custom Excel template that tracks everything. Start with a tab for exchange rates (monthly, yearly average, and year-end) that feeds into your conversion calculations. Then create a reconciliation tab that shows beginning CTA balance, current year adjustment, and ending balance. The key is maintaining good documentation. I attach this reconciliation to each year's return as a supporting statement, which has helped during two separate IRS reviews of my 1120F filings. If you're consistent in methodology and clearly document everything, you'll be fine regardless of which approach you take.

Has anyone had experience dealing with functional currency elections under Section 985 in connection with this issue? Wondering if making that election would simplify the filing process for future years even though it wouldn't help with the past unfiled returns.

•Yes! This is actually really important to consider. If your client's activities in the US are significant enough, making a functional currency election under 985 can eliminate these translation headaches going forward. You'd still need to handle the historical unfiled returns with the M-1 adjustment approach, but future filings become much simpler. The downside is there's a fair amount of work in the transition year, and you need to get approval from the IRS via a method change. Form 3115 would be required.

I've dealt with this exact situation multiple times with foreign clients who had unfiled 1120F returns. The M-1 adjustment approach is definitely the way to go for these currency translation differences. One thing I'd add is to be very careful about your exchange rate sources and document them thoroughly. I always use the Federal Reserve's daily exchange rates and create a detailed memo explaining the methodology - which rates were used for which items and why. This becomes crucial if you're ever questioned during an exam. Also, since you're dealing with multiple years of unfiled returns, consider whether you need to address any potential penalties under the reasonable cause provisions. The IRS tends to be more understanding when there's a legitimate business reason for the delay and you're making a good faith effort to comply correctly.
