Don't forget to check your state's rules too! Some states require you to file specialized forms showing the breakdown of sales tax by county or district. I got hit with a penalty because I reported everything correctly on my federal return but messed up the state filing. Each state has different requirements for how to document sales tax collected and remitted.

For anyone using QuickBooks, there's a specific way to handle this. Set up a separate account for sales tax collected, and when you run reports, make sure to exclude that account from your income reports. Then when you pay the tax to the state, it zeros out that account. Your 1099K will still show the full amount, but your accounting will clearly show what was sales tax vs actual income.

I ignored a CP24 notice once thinking it was no big deal. BIG mistake. The penalties and interest kept growing, and eventually they sent a CP504 threatening to levy my bank accounts. Had to set up a payment plan and ended up paying way more than the original amount. Whatever you do, don't just throw the letter in a drawer and forget about it!

I went through this exact same situation about 6 months ago with a CP24 notice for around $750. The anxiety was real! Here's what I learned that might help: First, take a deep breath - these notices are super common and usually straightforward to resolve. The key is acting quickly rather than letting it sit. What worked for me was gathering ALL my tax documents (W-2s, 1099s, bank statements, etc.) and doing a line-by-line comparison with what the IRS claimed I didn't report. In my case, they were right - I had completely forgotten about a small 1099-MISC from some freelance work I did early in the year. If you determine the IRS is correct (like I did), paying online through IRS Direct Pay is the fastest way to stop interest from accumulating. The process was actually pretty simple once I stopped panicking about it. But if you think there's an error, definitely dispute it. The notice should have instructions on how to respond. Just make sure you do it within the timeframe they specify (usually 30 days from the notice date). Either way, don't let this snowball like some people do. Address it now while it's still manageable. You've got this!

Has anyone used the IRS Free File options for handling education credits with 1098-T forms? I'm wondering if they're as good as the paid options for education credits.

I went through this exact same situation last year as a first-time college student! One thing that really helped me was double-checking that all my qualified expenses were accounted for. Beyond what's on your 1098-T, don't forget you can also claim required textbooks, lab fees, and even things like required course materials that you paid for separately. Since you're independent and made $22k, you should definitely qualify for the American Opportunity Credit which is way better than the Lifetime Learning Credit. The AOTC can give you up to $2,500 and up to $1,000 of that is refundable even if you don't owe any taxes. Also, keep all your receipts! I learned the hard way that the IRS might ask for documentation later. Make sure you have records of your textbook purchases, any lab fees, and other required course expenses that aren't included on the 1098-T. TurboTax should have a section where you can add these additional qualified expenses. One last tip - if your scholarship money was used for non-qualified expenses like room and board, that portion might be taxable income, so make sure TurboTax is handling that correctly too.

FYI - there's another situation where you need to file Schedule B regardless of the amount of interest or dividends: if you have any foreign accounts. I found this out the hard way after getting a notice from the IRS. Even if you only have $5 of interest total, if any of it came from a foreign bank account, you still need to file Schedule B and check that box in Part III.

Just wanted to add another important detail that I learned when I had to file Schedule B for the first time - you need to list ALL payers of interest and dividends on Schedule B, not just the ones that put you over the threshold. So even if you have 10 different accounts contributing small amounts that together exceed $1,500, you have to list every single payer on the form, including their name, address, and the amount they paid you. It can make for a pretty long form if you have accounts scattered across multiple banks and brokerages. The IRS uses this information for matching purposes - they want to see that what you're reporting matches up with all the 1099-INT and 1099-DIV forms they received about you. Missing even a small payer can trigger a notice later on.

Has anyone actually successfully contributed to two mega backdoor 401ks in the same year? My tax preparer said it would trigger an automatic audit, but I can't find any info confirming this.

This is such a valuable discussion! I've been navigating this exact scenario myself. One thing I want to emphasize is the importance of keeping detailed records when you're contributing to multiple unrelated employer plans. The IRS may not automatically flag high retirement contributions, but if you ever get audited, you'll need to prove that your employers are truly unrelated (not part of a controlled group or affiliated service group). I keep documentation showing the separate ownership structures, different EINs, and completely independent operations. Also, don't forget about the timing - make sure you're not exceeding the annual limits within the same calendar year. I use a spreadsheet to track contributions across both plans monthly to avoid any accidental over-contributions that would need to be corrected. Has anyone dealt with the situation where one employer gets acquired mid-year? I'm wondering if that would affect the separate 415(c) limits for the remainder of the year.
