Thanks for pointing this out! My income was definitely below those limits in 2021 (around $65k) so I was eligible for the full contribution. I think I might have been confused about how much I actually contributed - just double checked and it was exactly $6k, not $8k like I initially wrote. My memory isn't what it used to be lol. If I'm understanding everyone correctly, since the Roth contribution doesn't affect my tax liability and my income was too high for the Saver's Credit but below the Roth income limits, there's really no benefit to amending my return. Does that sound right?

That's exactly right. If your contribution was $6k (within the limit), your income was below the Roth IRA income thresholds but above the Saver's Credit limit, there's really no reason to amend your return. The IRS already has the information from the Form 5498 that your financial institution filed, and since Roth contributions don't impact your tax liability, you're good to go. One less thing to worry about!

Can you explain what a "backdoor Roth conversion" is? I keep hearing about it but don't really understand the concept or why it matters for record keeping.

I don't think I received any special credits last year - I don't have kids and didn't qualify for most of those pandemic-related things. My income did go up slightly (about $1,500 more than last year), but I didn't think that would make such a big difference. One thing I'm wondering about - I did start contributing to my company's 401k this past September. Would that affect my refund in any way? I'm putting in about 4% of my paycheck.

Your 401k contributions actually should have helped your tax situation, not hurt it. Those contributions reduce your taxable income, which typically means less tax overall. Since you started in September, you might not see the full annual benefit, but it definitely wouldn't cause your refund to decrease. Given all the information you've shared, it really does sound like the withholding change is the primary factor. The good news is that you didn't actually lose money - you just received it gradually throughout the year instead of in one lump sum. For next year, definitely submit a new W-4 requesting additional withholding if you prefer the larger refund approach to saving.

This is exactly right. A tax refund is just the government giving back money they took too much of during the year. Ideally, your refund should be close to zero - that means you paid exactly what you owed, no more no less.

That makes a lot of sense actually! The platform does take a percentage of earnings, so maybe the digital version showed net income while the paper shows gross? That would explain the difference. Should I still amend my return even if that's the case?

Yes, that's likely what happened. Regardless of the reason for the discrepancy, you should technically report what's on the official paper 1099 since that's what the IRS receives. Even if the digital showed post-fee income, the IRS expects you to report the gross amount and then deduct eligible fees as business expenses on your Schedule C. An amendment would be the proper course of action, though as others mentioned, the tax difference will be minimal. Just make sure if you're deducting business expenses that you include those platform fees as part of your deductions.

I wouldn't recommend ignoring it. Friend of mine ignored a $150 discrepancy and got a CP2000 notice about 18 months later. Ended up paying the extra tax plus interest. Not a huge deal but definitely more annoying than just fixing it upfront.

Would this still work if it's been like over a year since I worked there? I have a similar issue but from a job I had in 2023 and I just realized I never received one of my W-2s when organizing for this year's taxes.

Yes, it should still work! Most payroll systems keep your documents available for several years. I was able to log into my ADP account almost 2 years after leaving a job and still access all my tax documents. If you can't remember which payroll system they used, try contacting any former coworkers who might know. Even if you don't have login credentials anymore, these services usually have account recovery options using your SSN and personal info to verify your identity.

How much was the penalty when you got caught? I'm trying to decide if it's worth the hassle of tracking down a W-2 from a job where I only made like $1200 total.

Thanks for mentioning documentation! I think I have all my 1098-Ts from school but not sure about textbook receipts from 3 years ago. Will the IRS reject my amendment if I'm missing some of the receipts?

The IRS won't automatically reject your amendment if you're missing some receipts, but you should be prepared to substantiate your claims if they ask questions. For textbooks, if you don't have the original receipts, look for credit card statements, bank statements, or emails confirming your purchases. For education credits, the 1098-T is the most important document, as it shows your enrollment and amounts paid to the institution. The IRS is more likely to focus on verifying that information rather than every individual book purchase. Do your best to create a reasonable estimate of your textbook costs if you can't find all receipts, and keep notes on how you calculated those amounts.

Does the IRS automatically add the interest or do you have to request it specifically? And do you know what the current interest rate is?
