Is there a statute of limitations on back taxes? Like, if they haven't contacted me about unfiled taxes from 10 years ago, am I in the clear?

There's no statute of limitations for unfiled tax returns - the IRS can come after you at any time for returns that were never filed. However, once you do file, the general statute of limitations is 3 years for the IRS to audit or assess additional taxes (this extends to 6 years if you underreported your income by more than 25%). For refunds, you only have 3 years from the original due date to claim them. After that time passes, you lose the refund forever, even if you were owed money. That's why it's important to file, even years later - at minimum to start the statute of limitations clock and potentially claim refunds that aren't yet time-barred.

I used H&R Block for 4 years of back taxes and it was SO expensive - like $350 per year! In retrospect I should've just used software. Especially since they made a mistake on one of my returns that I had to fix anyway. Just make sure whatever you use has the right forms for your situation.

Exactly! My friend who runs a restaurant got convinced by one of these "specialists" to claim ERC based on dining capacity restrictions, which was legitimate. But then they pushed him to claim additional quarters when only OSHA guidance was in effect. Now he's worried about what will happen and the ERC company is nowhere to be found. They already took their 20% fee!

Do you think having a separate business banking account is absolutely necessary? I sell crocheted items on Etsy (maybe $1200/year) but just use my personal account and track everything in a spreadsheet. Would the IRS have an issue with that?

Having a separate business account isn't absolutely required by law, but it's one of the strongest indicators that you're treating your activity as a business rather than a hobby. It shows clear separation between personal and business finances, which is important if you're ever questioned. For a small Etsy operation like yours, a detailed spreadsheet is better than nothing, but I'd strongly recommend at least opening a free business checking account. Many banks offer them with no minimum balance. This simple step adds significant credibility to your business classification and makes tracking expenses much easier come tax time.

This is super important advice! My city requires a business license for ANY selling activity, even for my occasional pottery sales at craft fairs. The fee is small ($25/year) but the potential fine for operating without one is $500!

10 How did the IRS know you were only using it 30% for business? Did they just look at your mileage log, or did they have other ways of figuring it out?

22 The IRS asked for my mileage log during the audit, and I had only kept sporadic records. They compared the total miles on the vehicle to the business miles I could document, and it came out to around 30%. They also looked at my appointment calendar and client locations to verify whether my claimed business trips were legitimate. The auditor explained that without a contemporaneous mileage log (meaning one kept at the time of travel, not created later), they default to assuming more personal use. The burden of proof is entirely on you as the taxpayer to demonstrate business usage. Without proper documentation, you'll lose the deduction every time.

2 Bonus depreciation is different from Section 179 in a few key ways. For 2024, bonus depreciation is at 60% (down from 80% in 2023), and will drop to 40% in 2025. Unlike Section 179, bonus depreciation CAN create a loss for your business, which might be beneficial depending on your situation. For vehicles above 6,000 lbs, you could potentially get a larger first-year deduction using a combination of Section 179 (up to $27,000) and bonus depreciation on the remaining basis. For vehicles under 6,000 lbs, the luxury auto limits still apply even with bonus depreciation.

That's really interesting - I didn't realize education expenses could qualify for avoiding the penalty. About $6,000 of what I withdrew actually did go toward my final tuition payment. Would I need to file an amended return to claim this exception, or can I just dispute the CP49 notice directly?

You can address it directly in your response to the CP49 notice. You'll need to complete Form 5329 for the tax year in question, entering the distribution amount on line 1, then the amount used for qualified education expenses on line 2 of the "Exceptions" section. I'd also include proof of payment to your educational institution from that year. The IRS will recalculate your liability based on this information. Since it's been a few years, gather as much documentation as possible - receipts, account statements, anything showing you used those funds for education.

This is a really important point. When I cashed out part of my 401k years ago, they automatically withheld 20%. It should show on your 1099-R in Box 4. If withholding happened but wasn't accounted for in your original return, that could significantly reduce what you owe.
