Honestly, the quarterlies are annoying but not that hard once you set up a system. I've been selling on eBay for 10+ years and here's what works for me: 1) I set aside 30% of all my profits in a separate savings account 2) I use the IRS Direct Pay website to make payments each quarter 3) I keep it simple and just pay 25% of last year's total tax each quarter As long as you pay 100% of your previous year's tax liability (or 110% if your AGI was over $150k), you're safe from underpayment penalties. This "safe harbor" rule is your friend! Don't stress too much about the past - just start doing it correctly going forward. The penalties aren't massive if you've been paying in full by April 15 each year.

Yes, absolutely! When you make a payment through IRS Direct Pay, you'll get a confirmation number immediately after submitting the payment. I always screenshot this confirmation page and also write down the confirmation number in my records. You can also check the status of your payment on the IRS website using the "View Your Account Information" tool - just log in with your SSN and you can see all payments made to your account. I usually check this a few days after making each quarterly payment just to make sure it went through properly. Pro tip: I also set up email confirmations when I make the payments, so I get an electronic receipt sent to me automatically. Between the confirmation number, screenshot, and email receipt, I've never had any issues proving I made the payments on time.

This is a great discussion that touches on something I dealt with recently. One thing worth considering is the interaction between QBI losses and the overall Section 199A deduction limitation based on your taxable income. Even if you do generate future QBI to offset those carryforward losses, remember that the Section 199A deduction is still limited to 20% of your taxable income minus net capital gains. So if you're earning W2 income and have other deductions that reduce your taxable income significantly, you might not be able to fully utilize the QBI benefit even when you do have positive qualified business income. I learned this the hard way when I started a small side business thinking I could immediately benefit from my old QBI losses. The math worked out differently than I expected because of the taxable income limitation. It's another factor to consider when deciding whether to keep a dormant business alive or just close it cleanly. Also, regarding the state-level complications others mentioned - some states don't follow federal QBI rules at all, so you could be maintaining a business entity for federal tax benefits that don't even apply at the state level where you might owe annual fees or taxes.

The discussion here highlights just how complex QBI carryforwards can be in practice. I've been following a similar path - had QBI losses from a small manufacturing business that I wound down in 2021, and I've been wrestling with whether to maintain the entity. One aspect that hasn't been fully explored is the record-keeping burden of maintaining those carryforward losses over multiple years. The IRS expects you to be able to substantiate the original loss calculations if you ever use them, even years later. I've had to maintain detailed records of inventory valuations, asset dispositions, and final-year operating expenses that generated those losses. Also, if you're considering Muhammad's suggestion about starting a different type of business to utilize the losses, be aware that the character of the income matters. Some activities that might seem like "business income" could actually be classified differently for QBI purposes. For instance, if you start doing consulting that's considered a "specified service trade or business" under Section 199A, there are income limitations that could affect your ability to claim the deduction even with the carryforward losses. The practical reality for most people in W2 employment is that these QBI losses become "stranded assets" - technically valuable but practically unusable. Sometimes the cleanest approach is to close the business properly and move on, rather than maintaining it in hopes of someday utilizing losses that may never provide real benefit.

Yes, it definitely gets easier to predict over time! After going through a few vesting cycles, you'll have a much better sense of how the withholding works and whether you need to adjust. For your W-4 adjustment question - if you're consistently getting large refunds due to the 22% supplemental withholding being higher than your actual rate, you have a couple options. You could increase your allowances/decrease withholding on your regular salary to roughly offset the RSU over-withholding. Or you could use the extra withholding box on the new W-4 to specify a smaller additional amount to withhold from regular paychecks. Just be careful not to under-withhold overall - you want to stay within the safe harbor rules (either owe less than $1,000 at filing, or pay at least 100% of last year's tax liability through withholding and estimated payments). I'd recommend tracking one full year of RSU activity first before making major W-4 changes, since vesting amounts can vary and you want to see the full picture. Many people also find it helpful to set aside some of their RSU shares specifically for tax purposes if they're worried about under-withholding in higher tax brackets.

Great question about quarterly vesting! I've been dealing with the same situation for the past few years. For quarterly vesting, each vesting event is treated as a separate supplemental wage payment, so yes, each gets withheld at the flat 22% rate regardless of your year-to-date withholding. This can actually work in your favor or against you depending on your total compensation. If RSUs make up a large portion of your income and you're in a higher bracket (24%+), the 22% withholding on each quarterly vest might leave you short at tax time. But if you're in the 12% bracket, you'll likely get a nice refund. For tracking adequacy, I use a simple spreadsheet that shows: 1) Total expected RSU income for the year, 2) Expected withholding (roughly 22% federal + state + FICA), and 3) What I think my actual tax liability will be. This helps me decide if I need to adjust my regular W-4 or set aside additional shares. Regarding setting aside shares - yes, I mean keeping some of the actual shares you received (the ones not sold for withholding) as a tax reserve. Some people sell a portion of their remaining shares near year-end if they think they'll owe additional tax. Others just hold the shares and pay any additional tax from other sources. It really depends on your risk tolerance and whether you want to keep your equity exposure.

I'm working on a similar problem for my small business. Looking at these numbers: If gross assets went from $9.8M to $13.5M (+$3.7M) but accumulated depreciation decreased by $2.55M, doesn't that suggest they got rid of old assets and bought way more new ones?

This is a great discussion! I've been wrestling with similar Schedule L calculations for my consulting practice. One thing I'd add is that when you see that dramatic decrease in accumulated depreciation ($8.75M to $6.2M), it's almost certainly indicating major asset disposals. For a more complete capex calculation, you might want to try working backwards: 1) Start with the $3.7M increase in gross PPE (new acquisitions minus disposals at cost) 2) Estimate the original cost of disposed assets by looking at the accumulated depreciation reduction 3) Add back the estimated disposal amount to get total new purchases In your case, if they disposed of assets with $2.55M in accumulated depreciation, those assets likely had a much higher original cost. Without more details from other forms, it's hard to pin down the exact capex amount, but it's definitely more than the $3.7M net increase in gross assets. Have you checked if there's a Form 4797 (Sales of Business Property) that might give you more clarity on the disposals?

I've been following this thread and want to add some practical advice from my experience working in tax preparation. The support test calculations can seem overwhelming, but there's a systematic way to approach this. Create a simple monthly budget tracking sheet with two columns: "I pay" and "Parents pay." Include everything - rent, utilities (your estimated share), food, transportation, insurance, medical, education, clothing, entertainment, phone, etc. Multiply by 12 for annual totals. For your situation with cash rent payments, the IRS Publication 17 specifically mentions that you can use "reasonable estimates" when exact records aren't available. Your regular ATM withdrawals that match your rent amount, combined with a simple written statement from your dad acknowledging the arrangement, would be considered reasonable documentation. One often overlooked factor: if you're paying your dad $175/week for rent, that's actually market-rate documentation that you're providing your own housing support. Most parents charging a dependent child would charge much less or nothing at all. Also, don't forget that any financial aid or scholarships you receive don't count as support from your parents - they count as support you provided for yourself. This can significantly tip the scales in your favor. The bottom line: if your calculations show you provide more than 50% of your total support, file your return claiming yourself. The education credits alone could be worth $2,500, which likely exceeds any benefit your parents would get from claiming you.

I'm a CPA and want to emphasize something crucial that might get overlooked in all this discussion about documentation and worksheets: the IRS dependency tests are objective, not subjective. Your parents don't get to "choose" who claims you based on family dynamics or who feels entitled to the deduction. Based on what you've described - paying $9,100/year in rent, covering your own groceries, car insurance, and personal expenses, plus working 30 hours a week - you almost certainly provide more than half your own support. The fact that your mom pays tuition doesn't automatically disqualify you from claiming yourself. Here's what I'd recommend: Complete IRS Worksheet 3-1 in Publication 501 (the official support test worksheet). This will give you the exact calculation the IRS would use if there's ever a dispute. If you provide more than 50% of your total support, you SHOULD claim yourself - it's not optional, it's the correct filing status under tax law. Also, since you mentioned you're 24 and a full-time student, make sure you understand that you can only be claimed as a "qualifying child" if you're under 24 AND a full-time student. If you don't meet the qualifying child test, your parents would have to prove you're a "qualifying relative," which has even stricter support requirements. File your return first and claim yourself if the numbers support it. Let your parents deal with the rejection if they try to claim you incorrectly.
