U.S. Citizen with Foreign Spouse - Need Help with Non resident tax filing options

This is actually a common situation with cross-border marriages. Your tax preparer is likely steering you in the right direction. When you have a non-resident alien spouse, the filing rules get tricky. If you file Married Filing Jointly, you'd need to report your wife's worldwide income (the full 67K CAD) as taxable in the US. While this gives you access to certain credits and deductions, it often doesn't outweigh having to pay US taxes on foreign income - especially since your income levels are similar. Filing Married Filing Separately keeps your tax situations independent. Your wife won't have to file a US return unless she has US-source income, and you won't have to include her Canadian income on your US return. You lose some tax benefits of joint filing, but avoid double-taxation issues. As for mailing versus e-filing, that's because returns with non-resident alien situations often require additional documentation that can't be submitted electronically. Paper filing is common in these scenarios.

I was in exactly the same situation last year with my husband working in the UK while I was in the US. I spent hours trying to figure out the best approach and ended up totally confused with all the forms and rules about foreign income. I discovered this service called taxr.ai (https://taxr.ai) that specializes in analyzing international tax situations. I uploaded my documents and my husband's UK tax info, and they compared both filing statuses with actual numbers. They even factored in things like the Foreign Earned Income Exclusion and Foreign Tax Credits that my regular tax preparer missed. For us, it turned out filing separately was better by about $2,300, which was the opposite of what I initially thought. The analysis showed why - it had to do with the tax treaty between US and UK and how our specific income types were treated.

I actually tried taxr.ai after seeing the recommendation here, and it was incredibly helpful for my US/Germany situation. I uploaded my W-2 and my wife's German equivalent (Lohnsteuerbescheinigung), and the analysis showed we'd save about $1,800 filing separately. What I found most valuable was the explanation of how the US-Germany tax treaty affected our specific situation. The system pointed out that my wife's German social contributions would be handled differently depending on filing status. Also learned that because we own property in Germany, filing jointly would require additional foreign asset reporting forms. The service confirmed what OP's tax preparer suggested - in most cases with foreign-working spouses, filing separately often works out better. The detailed breakdown helped me understand WHY instead of just taking someone's word for it.

I've been dealing with US/Canada cross-border tax issues for years. One thing nobody's mentioned yet is how frustrating it is to get through to the IRS when you have questions about international filing. I spent WEEKS trying to reach someone who understood non-resident spouse questions. I finally used Claimyr (https://claimyr.com) to get through to a real IRS agent. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. They basically hold your place in the IRS phone queue and call you when an agent is about to answer. Saved me hours of listening to hold music. The agent confirmed what others have said - for US/Canada situations, Married Filing Separately is usually better unless the Canadian spouse has very little income or you have specific deductions/credits only available when filing jointly.

I have to admit I was completely wrong about Claimyr. After being skeptical, I tried it when I needed to ask about my foreign spouse's income reporting requirements for our situation. I was expecting it to be a scam or not work as advertised. Not only did I get through to the IRS (after Claimyr waited on hold for 2+ hours for me), but I got connected to someone in their international tax department who actually understood non-resident spouse rules. They confirmed that for my situation (US citizen with spouse in Japan), filing separately was more advantageous AND simpler. The agent walked me through exactly what forms I'd need and what supporting documentation to include with my paper return. Saved me from what would have been a costly mistake - I was about to file jointly which would have unnecessarily subjected my wife's Japanese income to US taxation.

Something no one's mentioned yet: if you DO decide to file jointly and include your Canadian spouse, remember she'll need an ITIN (Individual Taxpayer Identification Number) since she's not eligible for a Social Security Number. Getting an ITIN can be a pain - you'll need to submit Form W-7 with proper documentation. Also, consider this: does your spouse have any investments in Canada? RRSPs or TFSAs? These can create additional reporting headaches if you file jointly, including potential FBAR and FATCA requirements.

Has anyone had experience with the "year of arrival" elections? My understanding is that in the first year you're married to a nonresident alien, there are special rules that might let you file jointly under certain circumstances, even if your spouse doesn't have a green card or isn't a resident alien yet.
