Don't forget to check if you need to file an amended state return too! Depends on your state, but most require it if you amend your federal.

I was in almost the exact same situation last year - forgot about a W-2 from a part-time retail job and didn't realize until weeks after filing. The anxiety was real! But honestly, it's way more common than you think and totally fixable. Here's what I learned from going through it: File the 1040-X as soon as possible, but don't stress too much about the timeline. Since you caught it yourself before the IRS did, you're already ahead of the game. The additional tax on $3,800 probably won't be as scary as you think - mine was around $600 for similar income. One tip that saved me some headache: when you calculate what you owe, factor in any federal withholding that was on that forgotten W-2. A lot of people forget that part and think they owe more than they actually do. The withholding reduces what you'll need to pay with your amendment. You're doing the right thing by fixing it proactively. The IRS appreciates voluntary corrections way more than having to chase you down later!

Honestly, if you've been doing your own taxes since 2012, adding a 1099-SA and 1099-K isn't that big a jump in complexity. I'd try the DIY route first with a slightly better tax software than the free version. HR Block in person is crazy expensive for what you're describing - my sister paid $230 last year for something similar!

For your situation, I'd recommend starting with mid-tier tax software before jumping to in-person prep. TurboTax Deluxe or H&R Block Premium online will easily handle your 1099-SA and potential 1099-K for around $50-80, which is way less than the $150+ you'd pay in person. The 1099-SA is pretty straightforward - if you used your HSA money for qualified medical expenses, it's not taxable income. The 1099-K can look scary but it's just reporting payment processor transactions, not necessarily taxable income. You only owe taxes on actual profit from sales. Since you've been successfully filing your own taxes for over a decade, these additions aren't dramatically more complex. The software will walk you through both forms with interview-style questions. Save the money and try the DIY approach first - you can always go to a professional next year if you find it too complicated.

I'm in a very similar situation - small partnership that's been mostly dormant while waiting for our ERC to process. Based on all the responses here, I think I'm going to try TaxSlayer Business for around $70 since it seems like the most affordable option that still provides some guidance. The DIY route is tempting to save money, but I'm honestly worried about making mistakes on a partnership return, even a simple one. And while the taxr.ai recommendations are interesting, I'd rather stick with something more established for my first time doing this myself. Thanks everyone for the detailed breakdown of options - this thread has been incredibly helpful! It's reassuring to know there are affordable alternatives to the $200+ software packages.

I've been following this thread closely since I'm in an almost identical situation - partnership on hold waiting for ERC funds to come through. After reading all the suggestions here, I decided to go with TaxAct Business for around $80 this year. What really sold me was that several people mentioned it handles ERC-related entries well, which has been a concern of mine since our business situation is a bit unusual right now. The interface seemed more intuitive than TaxSlayer when I tried their demo, and the extra $10-15 felt worth it for the peace of mind. For anyone else in a similar boat, I'd recommend trying the free demos that most of these platforms offer before committing. It really helped me get a feel for which one would work best for my comfort level with tax software.

One thing I haven't seen mentioned yet is the importance of getting the appraisal documentation right. Since your lender is requiring the sale price to be listed at $650,000, make sure you get an independent appraisal that actually supports that value. The IRS could potentially challenge the gift of equity amount if the stated fair market value seems inflated. If the property truly appraises for $650,000, you're golden. But if it only appraises for, say, $500,000, then the actual gift would be $110,000 ($500k - $390k), not $260,000. This affects both the gift tax reporting for your in-laws and ensures the IRS doesn't question the transaction later. I'd recommend getting the appraisal done early in the process so you can adjust the numbers if needed before closing.

As someone who's worked in real estate tax planning, I'd strongly recommend getting both appraisals - one for the lender and an independent one for tax documentation. Many lenders will accept a slightly lower appraisal as long as the loan-to-value ratio still works with their requirements. The key is having solid documentation for the IRS that the fair market value supports your gift of equity calculation. If there's a significant discrepancy between appraisals, you'll want to understand why before closing. Sometimes it's just different methodologies, but occasionally it reveals that the initial value estimate was off. Also consider timing - if you can close this transaction in late December vs early January, it might give your in-laws more flexibility in managing the tax impact across different tax years. They could potentially make estimated payments or adjust withholdings to cover the additional tax liability.

I'm wondering if there are any special considerations for recent immigrants when updating information with the IRS? I've heard that some notifications are really important not to miss, especially if you're still establishing your status. Does anyone know if there's a way to set up email notifications instead of just relying on physical mail?

As someone who's been through this process multiple times, I'd recommend starting with Form 8822 right away since you mentioned you recently moved. The 4-6 week processing time is pretty standard, but don't wait - mail forwarding with USPS typically only lasts 12 months for first-class mail, and some IRS correspondence may not be forwardable. For your bank account updates, you're right that this is separate from address changes. If you're expecting a refund this year, you can still update your direct deposit info through the "Where's My Refund" tool on irs.gov, but only if your return is still being processed. One thing I learned the hard way: keep copies of everything you submit to the IRS, including the certified mail receipt if you choose to send Form 8822 via certified mail. This gives you proof of when you submitted the change request, which can be helpful if there are any delays or issues later. Since you mentioned being newer to the US system, don't hesitate to call the IRS line at 800-829-1040 about a week after mailing your form to confirm they received it. The wait times can be long, but it's worth it for peace of mind!
