That's a good point about documentation. Do you recommend any specific apps for tracking mileage? And how detailed do I need to be with the log - just start/end odometer readings or do I need to note every stop?

I've had good luck with MileIQ and Everlance for tracking business mileage. Both automatically detect trips and let you classify them as business or personal. For audit protection, you'll want to record the starting and ending odometer readings, date, business purpose, and destination for each trip. You don't need to document every single stop if they're all part of the same business purpose, but you should note the overall trip details. The IRS loves to target vehicle deductions during audits, so good documentation is essential. Take photos of the odometer readings periodically as additional backup.

Leasing isn't always better for tax purposes though. With a lease, you can only deduct the actual payments made each year. When purchasing, even if you can't use Section 179, bonus depreciation might still give a larger first-year deduction. Plus owning builds equity.

Does that Form 8822 need to be filed before or after submitting your tax return? I already filed with TurboTax but now I'm worried about this address issue.

You can file Form 8822 anytime - before, after, or completely separate from your tax return. It's basically just a standalone address update for the IRS's records. If you've already filed your return with your new address, filing Form 8822 afterward is still a good idea because it ensures the address change is processed across all IRS systems. Sometimes the address update from a tax return doesn't propagate to every IRS department.

YES! This happened to me too! I had to go back through each section carefully. Turns out TurboTax pulls your address from last year automatically, but then there's a separate section where you need to update your "current address" if you've moved. Super confusing interface. Check the personal info section again and make sure you updated both places.

9 That's a good point about initialing changes. Does this apply to all tax forms or just the W4? I sometimes make small corrections on other forms too.

4 Initialing changes is good practice for all tax forms, not just the W4. It's especially important for any form where you're providing information under penalty of perjury. For the W4 specifically, it's less critical since it's an internal form between you and your employer, but it's still a good habit. For forms that go directly to the IRS like your 1040, initialing changes can help prevent questions about who made the modifications.

5 I tried using it but found it confusing. It asked for too much detailed information that I didn't have on hand when filling out my W4.

Thanks for sharing your experience! That's really helpful to hear from someone in a similar situation. Did you have to fill out any special forms to document the support calculation, or did you just keep your own records in case of an audit?

We didn't have to submit any special forms with our tax return specifically for the support calculation. Our tax preparer just had us keep good documentation (basically a spreadsheet showing our household expenses and what portion went to our daughter). The most important thing was making sure our daughter's tax return properly indicated she could be claimed as a dependent on someone else's return. That way the systems don't flag a conflict. Keep records of major expenses you pay for your daughter in case you ever get questioned, but in our experience, this was a pretty straightforward situation once we understood the support test isn't about income but about who's paying for living expenses.

The kiddie tax only applies to unearned income (interest, dividends, capital gains, etc.), not earned income from actual work. Since OP's child is earning money from modeling/commercial work, that's considered earned income and would be taxed at the child's own rate, not the parents' rate.

This hobby vs business distinction is worrying me now. I definitely intend to make a profit, but with only $360 in income for 2024 and thousands in expenses, will the IRS see this as a legitimate business? We had the property listed on several rental sites but just had bad timing with the market in our area.

Don't worry too much - the IRS looks at your intent and efforts, not just your initial results. Save copies of your rental listings, any advertising you did, and documentation of your efforts to rent the property. This shows you were genuinely trying to operate as a business. The IRS generally allows new businesses some time to become profitable. They use a guideline that if you show a profit in 3 out of 5 consecutive years, they'll presume you have a profit motive. Your first year being mostly preparation is very common in real estate. Just make sure you keep excellent records of all expenses and your efforts to rent the property. This documentation will be crucial if you're ever questioned about your business intent.

I had a similar situation last year. You need to allocate expenses based on both time and usage. For example, if your property was available for rent for 3 months out of the year, you'd allocate 25% of annual expenses like insurance, property taxes, etc. to the rental activity. Then within those 3 months, if it was only actually rented for 10 days, you need to keep personal use vs. rental use straight too. Publication 527 has worksheets for this. It gets complicated fast!
