Thanks for this advice. I have been keeping emails, but I hadn't thought to document the phone calls with this level of detail. Do I need to submit this documentation with my tax return or just keep it in case of questions later?

You don't need to submit the documentation with your tax return unless you're filing by mail and want to include it as supporting evidence. But definitely keep it in your records for at least 3 years (the standard IRS lookback period for audits). If the IRS does question the discrepancy between your Form 4852 and what your employer reported, having this documentation ready shows you weren't trying to misrepresent anything - you were actively trying to get the correct information but had to file with what you knew was accurate. It demonstrates good faith on your part.

That's terrible advice. You should NEVER file knowingly incorrect tax information, regardless of the amount. That's literally asking for problems down the road.

I wasn't suggesting filing incorrect information! I was suggesting evaluating whether the correction is material enough to warrant the extra steps. For example, if box 12 is off by $5 due to a rounding error, that's very different than if it's off by $5,000. The IRS itself has de minimis rules for certain reporting requirements. I'm not saying to ignore significant errors, just to consider whether the particular error materially affects tax liability before going through the Form 4852 process.

Does this mean any child (regardless of age) can be a qualifying person for QSS as long as they live with you and you provide more than half their support? What about the gross income test that applies to dependents?

That's exactly right - for QSS purposes, a qualifying child can be any age as long as they're your child (including stepchild or adopted child), they lived with you for more than half the year, and you provided more than half their support. The gross income test that applies to dependents doesn't apply to the qualifying person test for QSS status. This is a key difference that causes confusion. Your adult child can have unlimited income and still be your qualifying person for QSS purposes, even if you can't claim them as a dependent because of their income.

Absolutely! File Form 1040-X to amend your previous return. You generally have 3 years from the date you filed your original return (or 2 years from when you paid the tax, whichever is later) to file an amendment. Definitely worth doing for $4K!

Does the ordering matter? Like what if I have both short-term and long-term losses carried over, and both short-term and long-term gains this year? Is there a specific way these have to be applied?

Yes, the ordering definitely matters because it can affect your tax rate. The IRS has specific rules for how losses and gains are netted against each other. First, short-term losses offset short-term gains, and long-term losses offset long-term gains. Then, if you have net losses in one category and net gains in the other, those net figures are used to offset each other. This is important because short-term gains are taxed at your ordinary income rate, while long-term gains get preferential tax rates.

You're absolutely right. You have to actually sell the investment (realize the loss) to claim it on your taxes. Holding onto stocks that have gone down in value doesn't create a tax loss you can claim - it's only when you sell them that the loss becomes "realized" and can be used on your tax return.

Thanks for confirming! That explains why I couldn't find any loss carryover from last year. At least i'll be able to use this year's losses to offset the gains I had earlier in the year, plus the $3000 against regular income.

Thanks for the insight! I did make around $8,900 over the summer, so that percentage makes sense. Do you think sharing my bank info with them is safe? That's my main concern honestly.

Sharing your bank info with a legitimate tax service is generally safe. They're handling millions of transactions and have security protocols in place. Account and routing numbers are actually printed on every check you write, so they're not your most sensitive financial information. That said, only provide this info through their secure portal, never via email or text. And if you're still uncomfortable, you can absolutely request a paper check instead as someone suggested earlier. It'll take longer but might give you more peace of mind. Most reputable companies offer both options.

THIS! I had the same experience. They called it a "refund management fee" on top of the tax prep fee I already paid. Check the paperwork you signed.

Do you ever help families set up the payroll stuff? My nanny keeps saying she wants to be "on the books" but neither of us know where to start.

I don't personally set it up for families, but I do point them toward resources. Many use household payroll services like HomePay, SurePayroll, or Poppins Payroll that specialize in nanny taxes. They handle all the paperwork, tax withholding, and filings for around $40-60/month. I also recommend they check the IRS Publication 926 (Household Employer's Tax Guide) which explains everything. Most families find that once they have a system set up, it's pretty easy to maintain and gives everyone peace of mind.

This whole thing sounds so complicated and expensive. Is it really worth doing all this for a part-time nanny? How much extra does it end up costing?
