I'm going through almost the exact same situation right now! I'm a dental hygienist who did fill-in work for about 6 months last year and just got hit with a massive tax bill that I wasn't expecting at all. Reading through all these responses has been incredibly helpful - especially learning about the self-employment tax being 15.3% on top of regular income tax. No wonder my bill was so high! I had no idea I'd be responsible for both the employer AND employee portions of Social Security and Medicare taxes. I'm definitely going to go back through my records and look for all those business expenses everyone mentioned. I bought several sets of scrubs, renewed my license, paid for continuing education, and drove to 4 different offices throughout the year. I kept most of my receipts but never thought to track mileage - lesson learned for next time! For anyone else in this boat, it sounds like the key is being really thorough about documenting legitimate business expenses on Schedule C. Even though the tax bill is still going to be substantial, every deduction helps reduce that painful self-employment tax calculation.

As someone who just went through this exact situation as a dental hygienist doing fill-in work, I completely understand your shock! The $2,000 tax bill hit me like a truck too when I first saw it. The key thing to understand is that your $9,200 from dental work isn't just subject to regular income tax - it also gets hit with self-employment tax of about 15.3% (Social Security and Medicare taxes that normally get split between you and an employer). On $9,200, that's roughly $1,300 in self-employment tax alone, plus whatever income tax applies. You definitely need to file Schedule C since you received a 1099-MISC. But here's the good news - you can reduce your tax burden by claiming legitimate business expenses. Things like: - Scrubs and uniforms (if they're specialized for dental work) - License renewal fees - Continuing education required for your license - Professional liability insurance - Mileage between different offices (not your regular commute) - Any dental tools or supplies you purchased Start gathering receipts and calculating your business mileage. Even if you don't have perfect records, you can reconstruct reasonable estimates based on your work schedule. Every deduction reduces both your income tax AND self-employment tax, so it's worth being thorough. The tax software is probably calculating correctly - it's just that nobody warned us about how self-employment taxes work! Set aside about 25-30% of any future 1099 income for taxes to avoid this surprise next year.

One thing nobody mentioned yet is that you should open a separate business checking account ASAP if you haven't already! Makes tracking business income and expenses sooooo much easier when tax time comes. I didn't do this my first year and spent like 3 full days sorting through personal bank statements to figure out what was business vs personal. Nightmare!

As someone who just went through this exact situation last year, I can offer some reassurance! You're not automatically doomed for missing those first two quarterly payments, especially since you literally didn't know about the business when the April deadline hit. The key thing is to make your September 15th payment and make it substantial enough to cover what you should have paid earlier. Since you started in March and have made $34,500 so far, you're looking at owing both regular income tax AND self-employment tax (that 15.3% Social Security/Medicare hit that nobody warns you about). Here's what saved me: I calculated what my total tax liability would be for the year, then made my September payment large enough to get me to that 90% threshold by year-end. The IRS is surprisingly reasonable about first-year businesses as long as you show good faith effort to catch up. Also, definitely start setting aside 25-30% of every payment you receive going forward. I use a separate savings account and transfer the tax money immediately when clients pay me. Trust me, you don't want to be scrambling to find tax money next April! Your photography business sounds like it's off to a great start - don't let the tax stress overshadow that success!

570 codes often pair with 971 notice codes. Check for that too. It's usually just verification. Nothing to panic about. Most clear in 2-3 weeks. Tax Advocate Service can help if it goes longer. They prioritize financial hardship cases. Keep checking your transcript weekly. Look for the 571 release code. That's your signal that processing has resumed.

I totally understand your frustration - once you're in their "system" it really does feel like you're flagged forever! I've been dealing with similar issues since a 2017 offset situation. One thing that helped me was setting up an online IRS account if you haven't already. Sometimes notices show up there before they're mailed, and you can see additional account details that don't appear on the basic transcript. Also, with three kids in activities, I know how tight budgets can be - consider reaching out to Tax Advocate Service (taxpayeradvocate.irs.gov) if this drags on beyond 30 days. They specifically help with cases involving economic burden and have more power to expedite reviews than regular customer service. Hang in there - most 570 codes with CTC do resolve within a few weeks, especially if everything on your return is accurate.

Just want to add something important about dual-status aliens and Form 5471 that hasn't been mentioned yet. Even though you don't need to file Form 5471 for shares sold before becoming a US resident, you might still need to report the sale on your dual-status return. If the sale of those foreign shares resulted in a capital gain, you'll need to report it on Schedule D and Form 8949, but only if it was US-source income or effectively connected with a US trade or business. Foreign-source capital gains realized during your non-resident period are generally not taxable in the US. Double check if you have any dividend income from those shares before selling them too. Depending on the source, those might need reporting.

Has anyone used TurboTax for a dual-status return with foreign income issues? I'm trying to figure out if it can handle Form 5471 correctly for part-year residents.

Has anyone in this thread used TurboTax for multiple LLC situations? Their interface seems to struggle with two separate Schedule Cs with different QBI calculations. I'm wondering if the OP's spreadsheet might actually be better than commercial software for this specific case.

This is really impressive work! As someone who's been through the frustration of CPAs missing obvious deductions, I totally get why you went the DIY route. Your spreadsheet approach sounds comprehensive. One area I'd suggest double-checking is the interaction between your home office deduction and the QBI calculation. The home office deduction reduces your Schedule C profit, which then reduces your QBI base. But if you're also claiming the home office deduction on Schedule A (for the non-business portion), make sure you're not double-dipping anywhere. Also, have you considered how state tax implications might affect your federal deduction strategy? Some states don't follow federal bonus depreciation rules, so maximizing federal deductions could actually increase your state tax burden. The fact that you're covering 13 different forms shows you're really thinking holistically about this. That's exactly what most tax preparers miss - they focus on individual forms instead of optimizing across the entire return.
