Do you know if having unfiled tax returns (even when not required to file) can affect things like financial aid applications or student loans? I'm in a similar situation for 2017 and 2018.

Having unfiled tax returns typically won't affect financial aid if you weren't required to file in those years. Most FAFSA forms and financial aid applications have a checkbox indicating "not required to file" for this reason. However, if you were required to file (based on your income and status) but didn't, that could potentially create issues with financial aid verification processes. Some schools select students for verification and may ask for tax transcripts or non-filing letters from the IRS. If you're concerned, you might want to request a "Verification of Non-filing Letter" from the IRS for those years, which confirms you weren't required to file.

Yes, you were likely required to file for 2019. The filing requirement is based on your gross income, not your final tax liability. For 2019, dependents generally needed to file if they earned more than $12,200 in wages OR had unearned income over $1,100 OR if self-employment income was over $400. With $7,500 in wages, you technically may not have needed to file based on the earned income threshold alone. However, if you had any federal tax withheld (check your W-2 box 2), you would want to file to get that money refunded. The standard deduction would likely have eliminated your tax liability, meaning you'd get all withholding back.

Thank you for the clarification! I just checked my 2019 W-2 and I had about $850 withheld in federal taxes. So I guess I missed out on getting that back since it's now 2025 and the three-year window has passed? That really sucks... At least I know for the future.

Does TaxAct force you to enter all those extra details for interest and dividends that the OP was complaining about? I hate when tax software asks for info that isn't actually required on the real forms.

TaxAct does ask for the payer names for interest and dividends, but it doesn't require all the excessive details like addresses and phone numbers. You can just enter the name and amount for each 1099-INT or 1099-DIV. For IRA distributions, you do need to enter each 1099-R separately, but that's actually correct since the distribution codes can be different. It's much less demanding than some of the other software I've tried.

Does your accountant e-file for you? I'm wondering if they have access to better tax software than what's available to regular consumers.

That's really helpful - I just checked my 1099-B and you're right, the cost basis shown is way off! So I need to use Form 8949 and check box "B" to make this correction? Do I need to include any supporting documentation with my return to explain the adjustment?

You don't need to include any additional documentation with your return to explain the adjustment. The IRS is familiar with this situation for RSUs. Just make sure you keep records of your RSU grant documents, vesting schedules, and the fair market value on vesting dates in case you're ever audited. When completing Form 8949, you'll enter the information from your 1099-B in columns a through e, then in column f enter code "B" (for basis adjustment), and in column g enter the difference between your correct basis and what's reported on the 1099-B. This effectively adjusts the basis to the correct amount for calculating your gain or loss.

How far back can you amend returns for this kind of mistake? I think I might have done the same thing for the past 3 years 😬

What's the 941-X form? My payroll company said they'd handle everything but now I'm worried they might miss something.

Form 941-X is the Adjusted Employer's Quarterly Federal Tax Return that you need to file to claim the ERC retroactively. It's essentially an amendment to your original quarterly tax filings. Most payroll companies are good with regular payroll processing but many don't have specialized experience with ERC claims on the 941-X. The form requires specific line items to be completed in a certain way to properly claim the credit. I'd recommend asking your payroll company specifically about their experience processing ERC claims via 941-X and what their success rate has been. If they seem vague or uncertain, you might want to consider a specialist firm instead.

I heard they resumed processing in January 2024 but they're going through claims much more slowly and with more scrutiny. Has anyone had an ERC claim processed successfully this year?

That's a really good point I hadn't considered. So you're saying that based on the residency test, my sister might not actually be eligible to claim my niece anymore since she's been living with me for most of the year? I definitely don't want either of us to get audited. Do you know if there's any exception to this residency test? Like if there's some kind of temporary arrangement or something? We didn't really think about the tax implications when my niece came to stay with me.

Yes, that's exactly what I'm saying. The residency test is pretty clear - a qualifying child must live with the taxpayer for more than half the year. With your niece living with you for 9+ months, your sister likely doesn't meet this requirement anymore. There are some exceptions to the residency test, but they're limited to specific situations like temporary absences (medical care, education, vacation, etc.), children of divorced or separated parents with a formal agreement, or kidnapped children. From what you've described, it doesn't sound like any of these exceptions would apply in your situation. I'd recommend having an honest conversation with your sister about the tax situation. The IRS would consider you to have the stronger claim to be the qualifying taxpayer for your niece based on the residency test.

This is the right answer! The residency test is super important for determining who can claim a dependent. If the niece lives with OP for most of the year, the sister technically shouldn't be claiming her unless there's a special exception. In my experience, the tax benefits for the person who has the child living with them (HOH status + child tax credits) are usually much better than just claiming a dependent who doesn't live with you. Might be worth both sisters calculating their taxes both ways to see what makes the most financial sense for the family as a whole.
