Do you think it would help to have some kind of written statement explaining why the home office was temporarily unusable? Like documenting the dates family was visiting and why it made the normal workspace unusable?

Absolutely - having a written explanation is extremely helpful. I'd document the dates your family was visiting, how it impacted your ability to work (noise, interruptions, privacy for client calls, etc.), and why the hotel was necessary to continue business operations. Keep this explanation with your tax records along with all your receipts and evidence of work performed at the hotel. If you're ever questioned, having this contemporaneous documentation shows you were thoughtful about the deduction rather than just claiming it without consideration.

Always track your own mileage with an app! Uber only tracks when you have a passenger or are en route to pick up. They don't track miles driving to hotspots or returning home after your last ride. I use Stride and it saved me over $2k in taxes last year from the extra miles.

Does anyone know if DHL is on the approved list? Can't seem to find a straight answer on this.

DHL Express 9:00, DHL Express 10:30, DHL Express 12:00, DHL Express Worldwide, DHL Express Envelope, DHL Import Express 10:30, DHL Import Express 12:00, and DHL Import Express Worldwide are all on the approved list. Here's an important note though - if you use any of these services, you must address your tax return to the street address on the IRS instructions, not a PO Box address. The private carriers can't deliver to PO Boxes.

Isn't there an "actual receipt rule" too? Like if the IRS physically receives your return before the deadline, it doesn't matter how you sent it? Or am I confusing this with something else?

Yes, you're absolutely right about the actual receipt rule! If the IRS physically receives your return before the deadline (regardless of how it was sent), it's considered timely filed. This is separate from the "timely mailing treated as timely filing" rule. So if you send something via regular mail or even hand-deliver it and the IRS gets it before the deadline, you're good to go. The timely mailing rule is basically a safety net for when your return arrives after the deadline but was sent on time using an approved method.

Thank you for pointing that out! I completely forgot to consider our mandatory CalSTRS contributions. We're both in the 2% at 60 structure (started teaching before 2013), so our contribution rate is slightly different, but it still helps reduce our MAGI. Do you know if there are any California-specific tax credits or deductions for educational expenses that might help us too? I've been focusing on the federal credits but wondering if I'm missing something at the state level.

You're welcome! Yes, the 2% at 60 structure has a slightly different contribution rate (10.25% for 2025), but it still makes a meaningful difference in your MAGI calculation. Unfortunately, California doesn't offer education tax credits that are as generous as the federal ones. There's no direct equivalent to the American Opportunity Credit at the state level. However, California does conform to many federal tax provisions, so the MAGI reduction from your retirement contributions will help with your state taxes too. You might also want to look into the College Access Tax Credit Fund, which offers a credit for contributions that help low-income California students attend college, though this doesn't directly relate to your children's expenses.

Is there an income limit for the student? My daughter makes about $8,000 a year from her part-time job while in college. Does that affect our ability to claim the credit?

Your daughter's income doesn't directly affect your ability to claim the American Opportunity Credit! The income limits for education credits are based on your (the parents') MAGI, not the student's earnings. However, there are a few things to keep in mind: First, if your daughter earned $8,000, she'll likely need to file her own tax return. Second, and more importantly, you need to make sure she doesn't claim herself as an exemption on her own return if you're planning to claim her as a dependent and take the education credit. As long as you're providing more than half of her support and she meets the other dependency tests, you can claim her as a dependent and take the education credit based on your MAGI thresholds, regardless of her part-time job income.

I'm using E*Trade right now. Their reporting is okay but nothing special. Does Fidelity actually flag potential wash sales BEFORE you make the trade? That would be super helpful since I've accidentally triggered those a few times without realizing it until tax time.

Yes, Fidelity's Active Trader Pro platform has a feature that shows warnings when you're about to make a trade that could trigger a wash sale. It's not perfect - you still need to understand the rules yourself - but it catches the obvious ones. They also provide a running tally of realized gains/losses categorized by short-term and long-term, which helps with tax planning throughout the year rather than waiting for tax season to get surprised. Their cost basis tracking is much more detailed than what I experienced with E*Trade, especially for partial lot sales which can get messy for tax reporting.

What's the threshold for when you need to make these quarterly payments? Is there a specific dollar amount or percentage?

Generally, you need to make quarterly estimated payments if you expect to owe $1,000 or more in taxes when you file your return. The safe harbor rule is that you need to pay either 90% of the current year's tax liability OR 100% of last year's tax liability (110% if your prior year AGI was over $150,000) through withholding and estimated payments combined. Since you're making $25-35k from trading on top of your regular income, you're probably hitting that threshold. I learned this the hard way when I got hit with underpayment penalties even though I paid everything I owed when filing. The IRS wants their money throughout the year, not all at once in April. You can make estimated payments online through EFTPS or mail them in quarterly (due dates are typically Jan 15, April 15, June 15, and Sept 15). Just calculate roughly what you'll owe on your trading profits and divide by four.
