I ran into this same issue and my accountant explained it this way: think of them as completely different transactions that just happen to involve the same account type. A Roth CONVERSION is taking money that was already in a tax-advantaged retirement account (Traditional IRA) and moving it to a different type of tax-advantaged account (Roth IRA). You already got the tax deduction when the money went into the Traditional IRA, so now you pay tax when converting to Roth. A Roth CONTRIBUTION is taking money from your regular bank account (money you've already paid income tax on) and putting it into a Roth IRA. There are strict annual limits on contributions ($7k-$8k depending on age).

Just want to add one more important point that helped me when I was in a similar situation - make sure you keep really good records of your Roth conversion for future reference. The $250K you converted will now grow tax-free in the Roth IRA, and when you eventually take distributions in retirement, you won't owe any tax on the growth. But you need to track the "basis" (the amount you already paid tax on through the conversion) versus any future growth. Also, remember the 5-year rule - even though your wife is 59, the converted amount has its own 5-year waiting period before it can be withdrawn penalty-free if needed. Each conversion has its own 5-year clock. This is different from regular contributions which have more flexible withdrawal rules. TurboTax should generate the proper forms (like Form 8606 if applicable) to track all this, but definitely save copies of everything including the 1099-R and your completed return for your records.

Something important nobody mentioned yet - if you're getting a tax refund for this year and file for bankruptcy, the trustee can take that refund and distribute it to creditors! I lost a $3,200 refund I was counting on when I filed Chapter 7 last year. Talk to your lawyer about timing if you're expecting a refund.

Don't forget that filing bankruptcy triggers a tax audit almost automatically. The IRS gets notified of all bankruptcy filings and often reviews unfiled returns or suspicious items. Make SURE you've filed all required tax returns before starting bankruptcy!

Has anyone successfully e-filed with this W-2/1042-S combination? I tried using H&R Block's software and it kept giving me errors when I entered the 1042-S information. Wonder if TurboTax or TaxAct handle it better or if I just need to file a paper return.

I'm dealing with this exact same situation right now! Working in the US for half the year then remotely from Germany. One thing I learned that might help others - make sure to check if your employer properly applied the tax treaty withholding rate on your 1042-S. The standard 30% withholding can often be reduced under tax treaties. For example, the US-Germany treaty allows for reduced rates on certain types of employment income. If your employer didn't apply the treaty rate, you can still claim the benefit when filing your return, but it means waiting longer for your refund. Also, keep really good records of which days you worked where. The IRS can be picky about the physical presence test for treaty benefits, especially if you're claiming reduced withholding rates. I created a simple spreadsheet tracking my location each workday just to be safe. Has anyone had luck getting their employer to retroactively apply the correct treaty withholding rate, or do you pretty much have to wait until tax filing to get the difference back?

Don't forget to complete Form 8833 if you're claiming treaty benefits! I made this mistake my first year as a resident alien.

@Ellie Simpson - I went through almost the exact same situation! Also forgot to update my bank after becoming a resident alien and got a 1042-S instead of a 1099-INT. FreeTaxUSA handled it just fine in my experience. When you get to the income section, look for "Foreign Income" or "Other Income" - there should be a specific option for 1042-S forms. Just enter the information exactly as it appears on your form (the $780 interest amount and the income code which is probably "01" for interest). The main thing is NOT to report it as 1099-INT income since they're different forms with different tax implications. Since no tax was withheld, you won't get any withholding credits, but you'll still need to pay regular income tax on the $780. Definitely submit that W-9 to your bank ASAP so you get proper 1099-INT forms next year. Most banks will process the change pretty quickly once you submit the form. One tip: double-check if your home country has a tax treaty with the US that might affect how this income is taxed. Some treaties provide benefits for interest income that could save you money, though you might need additional forms if you claim those benefits.

Just a heads up for anyone considering the dual-status election - if you switched from nonresident to resident alien mid-year like the OP, you might want to look into making the first-year choice election. This allows you to be treated as a resident for the entire tax year instead of having a dual-status year, which can simplify your filing significantly. You'd file Form 1040 with a statement attached explaining your election. The catch is you have to meet certain requirements (like being married to a US citizen or resident) and you'll be taxed on worldwide income for the full year. But it can eliminate the complexity of dealing with the 1042-S in the context of a dual-status return. Not everyone qualifies, but it's worth checking Publication 519 to see if this election makes sense for your situation. Sometimes the simplified filing process is worth potentially paying a bit more in taxes.

One thing I'd add that might help with the TurboTax confusion - when you get to the section about entering your 1042-S, don't panic if the software seems to categorize it strangely at first. The important thing is that you correctly identify yourself as a resident alien at the beginning of the interview process. Also, double-check that you're using the right version of TurboTax. The basic version often doesn't handle international tax situations well. You'll likely need TurboTax Deluxe or Premier to properly handle the 1042-S reporting and any foreign income you might have. If you're still having trouble, consider reaching out to your university's international student services office. Many schools have staff who are familiar with these exact tax situations and can point you toward resources or even provide workshops specifically for students dealing with residency status changes.
