Thanks for breaking it down like this! Super helpful. Quick question - should I use H&R Block for the amended return even though I was trying to use TurboTax for the side business part? I'm not sure if going back to H&R Block will be easier or if I should just start fresh with TurboTax for the amendment.

I'd recommend using H&R Block since they already have all your W-2 information and original return data in their system. Starting with TurboTax would mean re-entering all that information, which increases the chance of making errors. Most tax software keeps your information on file, so you should be able to log back into your H&R Block account and select the option to amend your return. This will pre-populate all your original information and let you add the additional schedules and income. It's generally much easier than starting from scratch with a different provider.

Does paying the owed tax immediately help avoid penalties even if the amended return takes forever to process? I'm in a similar boat with a side gig I forgot to report.

Do you still get the 1099-R if you do a hardship withdrawal? My husband needed emergency surgery last year and we took $25,000 from his 401k to cover costs insurance didn't pay. Will we get hit with penalties?

Yes, you'll still receive a 1099-R for hardship withdrawals. For medical expenses, there's a potential exception to the 10% early withdrawal penalty (though not to the regular income tax) if the medical expenses exceed 7.5% of your adjusted gross income. So let's say your combined AGI is $100,000 - medical expenses would need to exceed $7,500 to potentially qualify for the exception, and only the portion above that threshold would be exempt from the penalty. You'll need to file Form 5329 with your tax return to claim this exception. The $25,000 will still be counted as taxable income regardless, but you might be able to avoid at least some of the early withdrawal penalty.

This! I made this mistake a few years ago and overpaid my state taxes by almost $800. Double check ALL the boxes on your 1099-R, not just the main ones!

Thanks for the tips! Do you have a specific system you use to organize all this? I'm worried about keeping track of all these little expenses throughout the year. Also, do you know if there's a minimum amount I should even bother tracking? Like if I grab a $3 coffee for my plumber, is that even worth documenting?

I use a simple three-folder system that has worked great for me. One folder for receipts (I scan them with my phone), one for expense logs (I use a basic spreadsheet with date, vendor, amount, purpose, and recipient), and one for property-specific expenses. Regarding minimum amounts - technically there is no minimum threshold for documentation. Even that $3 coffee should be documented if you're deducting it. During my audit, the IRS agent specifically looked for patterns of small undocumented expenses that added up over time. Those small $3-5 purchases can easily add up to hundreds of dollars annually, which is why they check them. Better safe than sorry!

Did your accountant say anything about providing these regularly vs occasionally? I give my maintenance crew donuts like every Friday when they come to check properties. Would that still count as "during work" or is it too regular to be considered that?

What happens if my kid has both types of income but we elect to include it on our return? Do we still have to pay the SE taxes on their earned income?

If you include your child's income on your return using Form 8814, you can only do this for their unearned income (investments, interest, dividends, capital gains). For any earned income (like from a job or self-employment), your child must file their own return regardless. So yes, if they had self-employment income over the threshold (about $400), they would still need to file a separate return for that portion and pay the applicable SE taxes.

Qualified 529 distributions used for educational expenses aren't counted as income at all (neither earned nor unearned), so they won't affect Kiddie Tax calculations. Only if the distribution isn't used for qualified expenses would it potentially count toward the Kiddie Tax thresholds.

Thanks so much for clarifying! That's a relief to know the qualified 529 distributions won't complicate his tax situation. Now I just need to figure out how to handle the dividend income properly.

Hmm that's a really good point. I did get a promotion in August that bumped me from about $52k to the $58k range, so that could definitely be affecting things. Do you know if there's a good way to calculate the prorated amounts when your income changes mid-year?

You'll need to separate your income and withholding into two periods: before and after the promotion. For each period, calculate the annual equivalent of that income level (what you would have made if you'd earned that same amount all year), figure the tax on that annual amount, then prorate it for the number of months at that rate. For example, if you made $4,333/month ($52k/12) for 7 months, then $4,833/month for 5 months, you'd calculate: (Annual tax on $52k × 7/12) + (Annual tax on $58k × 5/12) = Your actual tax liability. Then compare your actual withholdings to this amount.

The IRS2Go app is really more for checking refund status than doing calculations. I'd recommend using the official Tax Withholding Estimator on the IRS website or something like FreeTaxUSA which lets you run scenarios for free.
