One thing nobody's mentioned yet - you can actually calculate exactly how much should be withheld using the worksheets in Publication 15-T from the IRS. It's a bit complicated, but it shows the exact formulas employers use to calculate your FITWH. For 2025, they've updated some of the withholding calculations, so what seems like "extra" withholding might actually be correct based on the new tables. The standard deduction and tax brackets have been adjusted for inflation.

As someone who's been through this exact situation, I'd recommend taking a systematic approach. First, definitely check with HR to see your actual W-4 form - sometimes there are transcription errors where payroll enters the wrong amount from what you wrote. Second, don't panic about the money already withheld - it's not lost, just prepaid to the IRS. You'll get it back when you file your return. Third, before making any changes, consider your overall tax situation. If you're single with one job and no other income, you probably don't need extra withholding. But if you have a working spouse, side income, or expect to owe taxes from other sources, that extra withholding might actually be protecting you from penalties. The IRS Withholding Calculator is free and pretty accurate if you want to double-check what your withholding should be. Just have your most recent paystub handy when you use it.

Alternatives to consider if FreeTaxUSA isn't working for your options trading: TurboTax Premier specifically handles negative proceeds from options trading correctly. It's more expensive but worth it if you have complicated trades. TaxAct also handles options better than FreeTaxUSA in my experience. If you've already entered most of your info in FreeTaxUSA and don't want to start over, the workaround others mentioned (using cost basis instead of negative proceeds) does work - I've done it for 3 years with no issues or letters from the IRS.

For anyone else who runs into this, here's the EXACT technical reason why you're seeing negative proceeds on your 1099-B with options trading: When you sell a cash secured put (CSP), you receive a premium. Later, if you buy to close that put option before expiration, you pay a premium. If you pay MORE to close the position than you received when opening it, that results in a negative proceeds value. Example: - Sell CSP: Receive $500 premium - Later buy to close: Pay $700 to close position - Net result: -$200 proceeds, $0 cost basis The IRS and brokers treat this correctly, but many tax software programs (including FreeTaxUSA) aren't designed to handle negative proceeds in their input forms.

One factor nobody is addressing is TIMING. Yes, mathematically it might work out similar in some cases, but getting reimbursed now vs. getting a tax deduction later is a huge cash flow advantage. Think about it - you get the $67 in your next check with reimbursement. With a deduction, you might wait 3-15 months to see that tax benefit, depending on when you file. Plus, the benefit is spread across your tax refund or reduced liability. For a contractor with lots of miles, this timing difference can be thousands of dollars in your pocket NOW vs. later.

Something I haven't seen mentioned yet is the impact on self-employment taxes. When you receive mileage reimbursement that gets reported as income on your Schedule C, it increases your self-employment tax liability (Social Security and Medicare taxes). However, when you deduct the mileage expense on the same Schedule C, it reduces your self-employment income by the same amount. So like others said, it's a wash for income tax purposes, but more importantly it's also a wash for self-employment tax. If you WEREN'T reimbursed and just took the deduction, you'd save on both income tax AND self-employment tax on that deduction amount. This is actually a small advantage to not being reimbursed, though the cash flow benefit of getting paid upfront usually outweighs this. The key is making sure your reimbursement rate matches the IRS standard rate ($0.67/mile for 2024). If your client pays less than the standard rate, you can deduct the difference!

I think everyone's missing an important question about the SALES TAX part. If you collect sales tax from customers, that money isn't actually yours - you're just collecting it for the state. When you file your sales tax returns with your state, you report both what you collected and what you paid. On your federal income taxes, you should NOT include the sales tax you collected as income. If your 1099-NEC incorrectly includes sales tax amounts, you need to subtract that from your income calculations.

This is really helpful information everyone! As someone new to self-employment, I was definitely overthinking this. It sounds like the key takeaway is that the 1099-NEC is just a tracking document - I still only report my actual business income once on Schedule C, and that includes everything clients paid me regardless of whether they issued a 1099 or not. The sales tax clarification is huge too. I've been charging sales tax but wasn't sure how it should appear on the 1099-NEC. It's reassuring to know that if a client mistakenly includes sales tax in the 1099 amount, I can offset it as an expense so I'm not paying income tax on money that belongs to the state. Thanks for breaking this down in plain English - much clearer than the IRS publications I was trying to decipher!

After dealing with K-1 issues for years, I've found that TaxAct Premium is the most affordable option that handles most K-1 situations correctly. It's about $70 for federal and state which is way cheaper than TurboTax or H&R Block's premium versions. Worth checking out if you're still looking for alternatives!

I ran into this exact same issue with FreeTaxUSA last year! It's super frustrating when you think you're all set to file and then hit that roadblock. From my experience, the problem is usually with specific items on the K-1 that require additional forms FreeTaxUSA doesn't support well. Since you mentioned it's a rental property investment, I'd bet the issue is related to passive activity limitations or at-risk rules. These often require Form 8582 (Passive Activity Loss Limitations) which FreeTaxUSA struggles with. Check Box 20 on your K-1 - if there are any letter codes there (especially A, B, C, or D), that's likely what's causing the problem. I ended up switching to TaxAct Premium that year and it handled everything smoothly. It's more expensive than FreeTaxUSA but still way cheaper than TurboTax. The switch was worth it to avoid the headache and make sure everything was filed correctly. Don't try to work around it by entering things manually - K-1s need to flow through the proper forms and schedules to avoid potential issues with the IRS later.
