I've been dealing with a similar situation and wanted to share what I learned after doing a deep dive into this. The IRS Publication 527 (Residential Rental Property) actually has specific guidance on this exact issue. The key test is whether you provide "substantial services" to your guests. Things like daily maid service, regular meal service, or concierge-type services would put you on Schedule C. But if you're just providing the typical Airbnb setup (cleaning between guests, basic amenities, maybe some snacks), that's Schedule E territory. One thing that really helped me understand this was looking at the self-employment tax angle. Schedule C income gets hit with the 15.3% SE tax, while Schedule E doesn't. So if your accountant correctly moved you from C to E, you're actually saving money on taxes even though the prep fee went up. The fee increase does sting though - maybe ask your accountant for a breakdown of what additional work Schedule E requires so you understand where that extra cost is coming from?

I went through this exact same confusion last year! My accountant made the same switch from Schedule C to Schedule E without explaining it, and I was so frustrated with the fee increase. After doing some research and talking to other Airbnb hosts, I learned that the IRS has been cracking down on this distinction lately. They're specifically looking for people who incorrectly use Schedule C when they should be using Schedule E. The good news is that if your setup is like mine (just cleaning between guests, providing basic amenities), Schedule E is probably correct AND you'll save money on self-employment taxes. That 15.3% SE tax doesn't apply to Schedule E rental income, so even with the higher prep fee, you might come out ahead. I'd definitely recommend asking your accountant for a detailed explanation of why they switched and what additional work Schedule E requires. A good tax preparer should be able to explain their reasoning clearly. If they can't or won't, it might be time to find someone new who communicates better about these important decisions.

I'm so sorry you're going through this - the 6+ month wait for an ITIN refund is absolutely maddening, but you're definitely not alone. This year has been particularly brutal for ITIN processing times. A few things that might help based on what I've learned from my own ITIN nightmare: 1. **Document everything** - Keep records of every time you've tried to call, including dates and times. This becomes important if you need to escalate to the Taxpayer Advocate Service later. 2. **Check for common ITIN red flags** - Since you mentioned this is your third year filing, make sure your name and address are formatted exactly the same way as previous years. Even small changes can trigger manual review. 3. **Try the early morning calling strategy** - Call 800-829-1040 right when they open (7 AM your time zone). Don't enter your ITIN when prompted - just wait through the menu options. Sometimes this routes you to a human faster. 4. **Consider your filing method** - You mentioned e-filing, which should be faster than paper, but some e-file providers have issues with ITIN validation that cause delays on the IRS side. The most important thing to remember is that after 6 months, you're definitely in "this needs escalation" territory. If you can demonstrate any financial hardship from the delay, the Taxpayer Advocate Service will take your case much more seriously. Hang in there - most people in your situation do eventually get their refunds, it's just an inexcusably long process.

I'm really sorry to hear about your frustrating experience with the IRS and your ITIN refund delay. Six months is definitely excessive, even for ITIN returns which typically take longer than regular SSN returns. A few additional suggestions that might help: **For reaching the IRS by phone:** Try calling the ITIN customer service line directly at 800-908-9982. This line is specifically for ITIN-related issues and sometimes has shorter wait times than the general line. Also, consider calling on Wednesdays or Thursdays mid-morning (around 10-11 AM) - I've found these times have slightly better success rates for getting through. **Check your mail carefully** - The IRS may have sent correspondence that got lost or misdelivered. Sometimes they request additional documentation for ITIN returns and if you don't respond (because you never received it), your return sits in limbo indefinitely. **Consider filing Form 911 (Request for Taxpayer Advocate Service)** - After 6 months with no contact from the IRS, you likely qualify for TAS assistance even without demonstrating significant financial hardship. They can expedite your case and get direct answers about what's causing the delay. The processing delays for ITIN returns this year have been particularly bad due to staffing issues and increased manual review requirements. While it's incredibly frustrating, most people do eventually receive their refunds - it's just taking much longer than it should. Stay persistent and document everything for your records.

I'm dealing with a similar situation right now - living in Canada and just received an IRS notice that's 6 weeks past the response deadline! Reading through all these responses has been really reassuring. One thing I want to add is that when you call the IRS international line, ask them specifically about Form 911 (Request for Taxpayer Advocate Service Assistance). If you're experiencing significant hardship due to the mail delays and can't resolve the issue through normal channels, the Taxpayer Advocate Service can intervene on your behalf. They have special authority to work with international taxpayers facing these kinds of systemic issues. Also, I've found that including a brief timeline in your response letter helps - something like "Notice dated [X], postmarked [Y], received [Z]" makes it crystal clear to whoever reviews your case that this was a mail delay issue, not procrastination on your part. Thanks to everyone who shared their experiences - it's made this whole situation feel much more manageable!

I'm currently facing this exact situation as well - received an IRS notice 5 weeks past their deadline while living in Germany. The stress has been overwhelming, but reading everyone's experiences here is incredibly helpful! One thing I wanted to add that hasn't been mentioned yet: if you're in a country that's part of a tax treaty with the US, you might want to reference that treaty in your response letter. Some treaties have specific provisions about correspondence and reasonable timeframes for international taxpayers. I found this information in IRS Publication 901 (U.S. Tax Treaties), and it gave me additional grounds to explain why the delay was beyond my control. Also, for anyone else dealing with this - I discovered that some international post offices will provide a "Certificate of Posting" retroactively if you can provide them with tracking numbers or other proof. This can serve as additional documentation that the letter was indeed sent much earlier than you received it. The anxiety about missing deadlines when you're overseas is real, but it sounds like the IRS is generally understanding about these situations when you respond promptly and document everything properly. Thanks to everyone who shared their stories - it's made this process feel much less scary!

Just be careful with DIY approaches if you have any complexity in your situation. I tried to file my own back taxes and accidentally missed a form, which resulted in the IRS sending me a terrifying letter 6 months later demanding additional money. If you're ONLY dealing with W-2 income and taking the standard deduction, you're probably fine doing it yourself. Otherwise, it might be worth investing in professional help.

As someone who works in tax preparation, I'd strongly recommend starting with the IRS website to download the prior year forms for free. For 2019, you'll need Form 1040 and the instructions are actually pretty straightforward for W-2 only income. A few key points that haven't been mentioned: First, make sure you have ALL your W-2s from each year - employers are required to keep copies for 4 years, so you can request duplicates if needed. Second, if you're expecting refunds (which is likely if you had standard withholding), there are no late filing penalties, but you do need to file 2019 by April 15th of this year to claim that refund. Before paying anyone $200 per return, try filling out one year yourself first. If it's truly just W-2 income with standard deduction, it's much simpler than you think. The IRS also has a helpline specifically for prior year returns at 1-800-829-1040 if you get stuck on specific questions. You can always pay for professional help later if you run into complications, but start with the free options first!

Kevin, regarding the Section 481(a) adjustment that Carmella mentioned - this is actually crucial for your conversion and often overlooked. The adjustment captures items that would be duplicated or omitted due to the accounting method change. Common timing differences include: 1) Accounts receivable at conversion date (income recorded under accrual but not yet received) 2) Accounts payable (expenses recorded under accrual but not yet paid) 3) Prepaid expenses that were deducted under accrual but payment spans multiple years 4) Accrued expenses like utilities or professional services For a consulting S-Corp, you'll likely have a positive adjustment (meaning you'll spread additional income over 4 years) due to outstanding receivables. The calculation involves comparing your books at year-end under both methods. As for California, they generally conform to federal accounting method rules but require their own Form 3115 equivalent (FTB 3115) to be filed. California also has a stricter interpretation of the business purpose test for educational expenses. For the MBA determination letter, that process typically takes 6+ months, so you won't get clarity before year-end. However, you could file a protective election and document your business purpose thoroughly. If questioned later, you'd have contemporaneous evidence of your reasoning. I'd strongly recommend getting a CPA involved for the Section 481(a) calculation - the math can get complex and mistakes are costly.

I went through this exact conversion for my single-member S-Corp consulting business last year and wanted to share some lessons learned that might help you avoid the pitfalls I encountered. First, regarding your owner investment transactions - you're on the right track, but be careful about the computer hardware classification. Under cash basis, if the computer cost more than $2,500, you might need to capitalize it rather than expense it immediately, even though you paid cash. The IRS has specific rules about tangible property that apply regardless of your accounting method. For payroll, I found that Wave actually handles cash basis payroll pretty well once you adjust the settings. You're correct that you'd record everything when cash flows out, but make sure you're still tracking your employer tax liabilities properly since those have specific payment deadlines that don't always align with payroll dates. The MBA tuition situation is where I'd be most cautious. I tried a similar prepayment strategy and ended up having to amend my return after my CPA pointed out that the IRS often views large educational prepayments by single-member S-Corps as constructive dividends, especially when the education could qualify the owner for work outside their current business scope. The safe harbor rules are stricter than many people realize. One thing nobody mentioned yet - consider the impact on your Qualified Business Income (QBI) deduction under Section 199A. Converting to cash basis and making large prepayments can significantly affect your QBI calculation, potentially reducing the 20% deduction benefit. Have you considered spreading the conversion over two tax years to minimize the Section 481(a) adjustment impact?
