Thanks for this! I had no idea about Form 8843 being required even without income. Do you know if there's a deadline difference for that form compared to the regular tax filing deadline?

The Form 8843 follows the same deadline as your tax return, which is generally April 15th for the previous tax year. However, if you don't have any income to report and are ONLY filing Form 8843 (no 1040-NR needed), then you actually have until June 15th to submit it. Since you mentioned having research assistant income, you'll need to file both Form 8843 and Form 1040-NR by the April 15th deadline (unless you file for an extension). Make sure you keep copies of everything you submit - international student tax records can be important for future visa applications or if you eventually apply for permanent residency.

Most free services don't support Form 1040-NR which international students need to file. I tried FreeTaxUSA last year and had to stop halfway when I realized it wasn't designed for nonresident aliens. Ended up using Sprintax which costs money but handles both federal and state correctly for F1 students.

That's good to know about responding within the deadline regardless. My notice says I have until May 3rd to respond. Do you know if a partial response is better than nothing if I'm still gathering all my documentation?

Absolutely - a partial response is much better than no response. Just make sure to clearly state in your letter that you're still gathering additional documentation and will submit it as soon as possible. I'd suggest sending what you have by the deadline along with a letter explaining your situation and requesting an extension for the remaining documentation. Be specific about what additional records you're trying to obtain and when you expect to have them. The key is showing the IRS you're actively working on resolving the issue, not ignoring it.

This is super important advice! Happened to me with Kraken - they sent a corrected 1099 but the IRS used the original incorrect one for my CP2000 notice. Took me forever to straighten out.

No kids in our situation, so I don't think Head of Household would apply to me. Do you know if there's any specific documentation the IRS required when you changed your status? Did they ever question your international marriage?

The IRS never specifically questioned my international marriage documentation. What seemed to matter more was proving my living situation for Head of Household status - I kept utility bills, rent receipts, and childcare documents showing I maintained the household separately. For your situation without children, you're right that Head of Household wouldn't apply. Since you don't have a formal divorce or legal separation yet, the IRS would technically still consider you married on December 31st. Married Filing Separately would likely be your only option unless you can finalize a legal separation document before the end of the year.

Unfortunately, the IRS is pretty strict about this. I tried filing as single when separated from my German husband and got a letter from the IRS months later questioning my filing status. Had to refile as married filing separately and pay penalties. Unless you have that legal document, they consider you married on Dec 31 = married for tax purposes.

Yes! I did this last year. When you file your return, there's an option to apply your refund to next year's estimated taxes, but for past balances you need to call them. Once you have your return processed and the overpayment confirmed, call and ask them to apply it to your outstanding balance instead of issuing a refund.

That's impressive! I had a similar issue with a 1099-K that was issued in error by a payment processor. They reported the gross amount of money that passed through my account (including refunds and personal transfers) as income. Took three letters and almost 5 months, but finally got it resolved. The CP2000 notice is scary when you first get it, but it's just a proposal and definitely worth contesting if there's an error!

Thanks for mentioning this. I do have 2 qualifying dependents (my kids), and I'm 32, so I should be eligible. Does the amount of unemployment I received last year affect my eligibility at all? Or is it just about the earned income portion?

You're definitely eligible with your two qualifying dependents and being over 25. The age requirement is only an issue for people without qualifying dependents. The amount of unemployment you received doesn't affect your EITC eligibility directly because unemployment benefits don't count as earned income. EITC is specifically based on earned income (like wages, salaries, tips, or self-employment). Your unemployment benefits still count as income for other tax purposes, but for EITC calculations, only your $1,300 in earned income would normally be considered - which is why using last year's earned income through the lookback provision would likely benefit you significantly.

In FreeTaxUSA, you have to go to the "Credits" section, then look for "Earned Income Credit." There should be a question asking if you want to use your 2023 earned income instead of your 2024 earned income. It's not super obvious but it's definitely there! I just did mine last week.
