What about hybrid workers who split time between US and international locations? We have several people who work 3 months abroad, 9 months in the US. How would you calculate that?

For hybrid workers splitting time between US and international locations, you'd need to track their time and allocate accordingly. For your example of someone working 3 months abroad and 9 months in the US, you'd allocate 25% of their R&D salary to the 15-year amortization schedule (foreign) and 75% to the 5-year schedule (domestic). Documentation is absolutely critical here. Make sure you have systems tracking where work is performed, not just where the employee's home base is. Some companies use IP address logging or formal documentation of work locations to support their allocations in case of audit.

We use TaxMatrix Pro which has a decent R&D module. It's not perfect but it lets you set up different amortization schedules and track them year over year. The reporting is decent for tax time too.

Can you explain more about the accountable plan option? I have an S-Corp for my online business and my CPA never mentioned this as a possibility. Currently not taking any home office deduction at all because I was told I couldn't.

An accountable plan is basically a formal arrangement where your S-Corp reimburses you for legitimate business expenses you incur personally - including home office expenses. The key benefit is that the reimbursements aren't considered taxable income to you, but the corporation can still deduct them. You'll need to document the business use of your home (square footage calculations, exclusive use, etc.), calculate the expenses properly, and have formal documentation showing the corporation approved this arrangement. The business would then reimburse you periodically based on actual expenses. This avoids the "rental payment" situation your tax preparer was concerned about. Many CPAs aren't familiar with this approach, so it might be worth finding one who specializes in small business/S-Corp taxation.

I got audited in 2021 specifically for my home office deduction! They wanted proof that the space was used exclusively for business. I had to provide photos, a floor plan with measurements, and receipts for business equipment in that room. They also asked for a written explanation of business activities conducted in the space.

Do you know if I need to bring my actual tax return paperwork to the appointment? I used TurboTax and don't have a printed copy of everything. Would just my W-2s and ID be enough?

For identity verification appointments, you don't need your complete tax return paperwork if you filed electronically. Your photo ID, Social Security card, and W-2s should be sufficient as they're mainly verifying you are who you claim to be. If you can access a summary of your return from TurboTax (even just on your phone), that would be helpful but not strictly necessary. They mainly need to match your ID with the person who should be receiving the refund, along with verifying your income information matches what was submitted.

Is there any way to check if your address is correct with the IRS without calling them? Their phone lines are always jammed and I'm worried I might be in the same situation.

Would you need to fill out a new W-4 form for this? Or can you just ask payroll to withhold an additional specific amount each paycheck? I've never adjusted my withholding before and don't want to mess anything up.

You would need to submit a new W-4 form to your employer. There's a section on the form (Step 4c) where you can specify an additional amount you want withheld from each paycheck. You don't necessarily need to complete the whole form again. Many employers will let you just indicate the additional amount you want withheld. I'd recommend using the IRS Tax Withholding Estimator on the IRS website to calculate how much extra you should have taken out based on this new income. It's much better to handle this now than to get surprised with a tax bill next April!

No, there's no requirement for employers to gross up the amount. It's completely at their discretion. But it's definitely not a favor if they're just converting the same dollar amount from non-taxable to taxable!

Thanks for clearing that up. I figured that was the case but wanted to check. Guess I'll be having a chat with my manager tomorrow with some calculations in hand!

I've considered that, but the inheritance left me really overweighted in just two sectors (finance and healthcare). The financial advisor at Vanguard recommended I diversify since these stocks now make up almost 30% of my total portfolio. I'm just trying to be smart about when and how I make the transition to minimize the tax hit.

I understand wanting to diversify, but consider doing it gradually over a couple of tax years instead of all at once. You could sell enough this year to stay in a lower tax bracket, then do the rest next year. Also worth checking if any of these companies offer dividend reinvestment plans (DRIPs). If they do, you could potentially shift some portion to those programs and slowly diversify without selling and triggering capital gains.

That's actually incorrect. The wash sale rule only applies when you sell at a LOSS and then rebuy within 30 days. OP is dealing with GAINS, so the wash sale rule isn't relevant here at all. Plus, what would be the point of selling at a gain, paying taxes, and immediately rebuying? That would just create a tax bill with no benefit.
