As another international student who went through this exact nightmare, I can confirm that the signature rejection is incredibly common for us non-US filers. The IRS seems to have stricter standards for international returns, probably due to fraud prevention measures. Here's what I learned from my experience: First, make absolutely sure you're signing with your complete legal name exactly as it appears on your visa and other US immigration documents. Second, use the US date format (MM/DD/YYYY) - this catches a lot of international filers. Third, ensure your signature is directly on the designated signature line with blue or black ink only. One thing that really helped me was including a brief cover letter with my resubmission stating "Corrected signature resubmission per IRS notice dated [date]" along with a copy of the original rejection letter. This seemed to speed up processing since they knew exactly what to look for. Given the international mail delays, I'd strongly recommend using a tracked courier service like DHL or FedEx. Yes, it costs more, but it's worth it to ensure your documents actually arrive and you can track delivery. The regular postal service can be unreliable for international tax documents. Don't stress too much about the deadline - as long as you respond within the timeframe specified in their letter, you'll be fine. The IRS understands that international mail takes longer, and they do make accommodations for that.

I went through this exact same situation last year as an Australian student! The signature rejection is so common for international filers that I'm convinced they have extra scrutiny on our returns. After getting the same Form 9134, I discovered my issue was actually a combination of problems: I had used the Australian date format (DD/MM/YYYY), my signature was too casual/abbreviated, and I hadn't realized that as a non-resident, there are slightly different signature requirements. What worked for me: I re-signed using my complete full legal name very clearly in black ink, used the US date format (MM/DD/YYYY), and made sure to sign directly on the signature line (not above or below it). I also included a brief cover letter referencing the notice date and sent it via Australia Post's tracked international service. The whole process took about 8 weeks from resubmission to receiving my refund check, but it did work out in the end. The key is being extra careful with the details since we don't get the luxury of quick follow-up if something goes wrong again with international mail times. One thing that really helped was calling the IRS early morning their time (which was evening for me in Australia) to confirm exactly what they needed. The wait was long but the agent was actually quite helpful once I got through.

Has anyone here actually been audited for HSA withdrawals? What was that experience like? I'm in a similar boat with about $45k in my HSA and planning to use some for a down payment on a house.

I withdrew $25k from my HSA last year for qualified medical expenses and didn't have any issues. The key is really having solid documentation - I created a spreadsheet that listed each expense with the date, amount, provider, and what it was for, then matched each one to a receipt or EOB. One thing I learned is that you want to be extra careful about expenses that might be borderline. Things like over-the-counter medications are only qualified if prescribed by a doctor, and certain medical equipment needs to be primarily for medical care. I had a few massage therapy sessions that I wasn't 100% sure about, so I excluded those from my reimbursement just to be safe. The IRS cares way more about whether your expenses are actually qualified than the dollar amount you're withdrawing. As long as you have legitimate medical expenses and good records, you should be fine. Just make sure to keep everything organized in case you do get questioned later.

Has anyone dealt with this situation while being unmarried co-owners? My girlfriend and I bought a place together but aren't married, and I'm wondering if the rules are different for us compared to married couples when it comes to splitting mortgage interest.

This is such a helpful thread! I'm dealing with a similar but slightly different situation - my spouse and I have uneven ownership (I own 30%, he owns 70%) on a $950K mortgage. Based on what everyone's explained here, I think I understand the calculation but want to make sure I'm doing it right. Since our mortgage is above the $750K limit, only about 78.9% ($750K/$950K) of our interest would be deductible. Then we'd split that deductible portion according to our ownership percentages - so I'd get 30% of the deductible amount and he'd get 70%. Does that sound correct? Also, for those who've gone through this before - do you keep any specific documentation beyond the deed and mortgage statements to support the ownership split in case of an audit?

For the actual numbers - I have a service business in a different field (legal consulting) that's about your size. My CPA had me do a compensation study showing average salaries for people in our field. Based on my study, I pay myself $700k salary on about $3.5M net. My wife is officially our CFO with a $250k salary for 30 hours/week. We documented both with formal job descriptions, board minutes approving the compensation, and market research showing comparable positions. Haven't had any issues with IRS in 6 years.

With $3.9M net profit, your $500k salary is definitely on the low side and could trigger IRS scrutiny. Most tax professionals recommend 40-60% of net profit as wages for service-based S Corps where the owner is the primary value generator. A few key concerns with your situation: 1) **Salary ratio**: At ~13% of net profit, you're well below what the IRS typically expects for a consulting business. Consider bumping to at least $1.5-2M to be safer. 2) **Family client concentration**: 90% revenue from your cousin's company creates additional risk. The IRS might view this as disguised employment or income shifting between family members. Document everything - contracts, deliverables, market-rate justification. 3) **Wife's compensation**: $325k for 25 hours/week needs very strong justification. That's equivalent to a $650k full-time salary, which is a huge jump from her $40/hr independent rate. Consider something closer to $120-150k unless she has executive-level responsibilities that truly command those rates. The family connections will definitely draw extra attention if audited, so documentation is crucial. I'd recommend getting a formal compensation study done and having written job descriptions for both positions.

Has anyone here successfully claimed a refund for Social Security taxes that were incorrectly withheld during their first two years on a J1? My university withheld FICA taxes from my first paycheck in 2023 all the way through 2024, and I only recently learned I shouldn't have been paying these taxes during that time. I've heard you can file Form 843 "Claim for Refund and Request for Abatement" along with a statement from your employer, but I'm wondering if anyone has actually gone through this process successfully.

I went through this exact same situation last year! I'm a J1 research scholar from India, and my university started withholding Social Security taxes in January 2024 after I had been exempt for my first two calendar years (2022-2023). What really helped me understand the timing was learning that the IRS counts any part of a calendar year as a full year for the exemption. So even though you only arrived in September 2023, that counts as your first year, 2024 as your second, and now 2025 is when the exemption ends. One thing to double-check is whether India and the US have a totalization agreement that might affect your situation. India doesn't have one with the US, so I definitely had to start paying once my exemption period ended. But since you mentioned you're from Brazil, and I saw in the comments that Brazil does have a totalization agreement, you might want to look into whether you can get a certificate of coverage from Brazilian social security authorities. Also, make sure your university is correctly calculating this. Some payroll departments make mistakes with international employees. I'd recommend getting a written explanation from them about why they're starting the withholding now, just to have it documented.
