That exclusive use requirement is so tricky! I have a home daycare and the IRS has different rules specifically for daycare providers. We can claim spaces that have mixed use (like kitchen, bathroom) based on time used for business. I wonder if there's any similar exception for pet boarding? Might be worth looking into.

That's a really good point. Do you think I need to file amended returns for previous years? Or could I just start doing it correctly going forward? I'm a bit worried about opening a can of worms if I start amending returns.

Generally, if you discover an error on past returns, you should file amended returns. However, there's a 3-year statute of limitations on most tax issues, so you'd typically only need to amend returns from the past 3 years. That said, this isn't necessarily a black-and-white error. There are legitimate situations where rental arrangements between yourself and your business can be appropriate, especially if you have the right business structure. Before amending anything, I'd recommend getting that third opinion from someone who can look at your specific situation. If you do need to amend, a tax professional can help you present the changes in the most favorable light, possibly reducing or eliminating penalties. Sometimes when you self-disclose and correct issues, the IRS is more lenient than if they discover the issue during an audit.

Do you need to bring anything specific to the appointment? I'm thinking of doing this but not sure what to take with me.

You need to bring your photo ID, social security card or tax ID number, and all relevant tax documents for your situation. In your case, that would mean your original return, the completed 1040-X form you plan to submit, and all supporting documents including your W2 form. It's also helpful to bring any notices you've received from the IRS about the issue you're trying to fix. Make an appointment online or by phone before going - they don't take walk-ins anymore.

It's because the IRS systems are super outdated. They still process paper returns using technology from the 1960s. That's why there are so many weird rules about how to attach documents.

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.

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.
