I do occasional work from home (maybe 1-2 days a month when projects need extra attention). Would that be enough to qualify my home as a "principal place of business"? And if it did qualify, would the deduction be worth the risk of triggering an audit?

Working from home only 1-2 days a month likely wouldn't be enough to qualify your home as a "principal place of business." For this approach to work, your home office would need to be: 1) Used exclusively and regularly for business (a dedicated space), and 2) The primary place where you conduct your business activities, or where you conduct administrative/management activities if you have no other fixed location for those tasks. Regarding audit risk, it's not worth claiming something questionable. The IRS has been increasing scrutiny on home office and travel deductions, especially when the amounts are substantial. Instead, focus on maximizing other legitimate deductions like retirement contributions, health savings accounts, or educational expenses if applicable to your situation.

This is the actual answer. Tax deductions for commuting rarely work out, but employer programs can save you thousands. My company gives us pre-tax transit cards that save me about 30% on subway costs. Ask your HR department!

Is this something that employers automatically withhold or is it something you have to pay at tax time? I'm getting close to that range with all my overtime this year.

Employers are supposed to automatically withhold the Additional Medicare Tax once your wages exceed $200k for the year. However, there's a quirk: if you have multiple jobs or your spouse works and you file jointly, your combined income might exceed the threshold even if no single employer pays you over $200k. In that case, your employers won't withhold the extra 0.9%, and you'll need to either make estimated tax payments or be prepared to pay it when you file. You can also request additional withholding on your W-4 to cover it. It caught me by surprise because I had two jobs last year that together put me over the threshold.

This is really important. I live in California and the state brackets have even more dramatic jumps than federal. My overtime last year pushed me from 8% to 9.3% state tax bracket and it definitely took a bite out of those extra earnings.

So true! My 1099-K was about $4,200 higher than my actual product sales because it included both sales tax AND shipping charges. I almost missed this until my tax preparer caught it.

Does anyone know if fees the platform charges get included in the 1099-K? Like if Etsy charges me a 5% transaction fee, is that getting subtracted before the 1099-K amount or do I need to deduct those fees separately too?

No, that's not a good idea. The IRS computers automatically track your 8606 history, and discrepancies can trigger notices or audits. A friend of mine tried to "start fresh" instead of carrying forward their basis and got a CP2000 notice. Had to file an amended return and pay interest. The IRS is surprisingly efficient at tracking these specific forms.

I appreciate the heads up about this! I hadn't realized the IRS specifically tracks the 8606 history so closely. I guess I've just been lucky so far not to get flagged. Sounds like I should probably go back and amend my returns to properly carry forward that basis. Better to fix it myself than wait for them to find it and potentially pay penalties and interest.

That's actually incorrect. The Form 8606 instructions specifically address this situation. When you convert less than your basis (whether due to investment losses or partial conversion), the difference remains as basis to be tracked on future Form 8606s. Line 14 is literally defined as "your basis in traditional IRAs" - not just for accounts with money still in them. The basis exists separate from the account balance. This is why Form 8606 needs to be filed even in years you don't make new contributions but still have basis. Your accountant may have made an error in your situation. I'd recommend checking your prior returns.

I did call them actually! They basically just confirmed what the 1098 shows - that the actual payment to the county hadn't been made yet in 2023. They said they could provide a statement showing my escrow contributions, but they were clear that doesn't change when the tax was technically "paid" for IRS purposes. Frustrating but at least consistent with what everyone here is saying.

In TurboTax, the property tax paid will typically import automatically if you have your 1098 imported electronically. If not, you'd enter it manually in the "Deductions & Credits" section under "Home Mortgage Interest and Real Estate Taxes." Look for the section about Form 1098 and it will ask for the amount in Box 11 (which is where property taxes paid by your mortgage company appear).
