Interesting! Do you know how this compares to standard credit card or loan interest rates? Is the IRS charging more or less than what a typical bank would charge for late payments?

The IRS interest rate of 7% is significantly lower than most credit card interest rates, which typically range from 18-25% or even higher. It's also generally lower than personal loan rates, which average around 11-15% for most borrowers. This is actually why some financial advisors suggest that if you're facing both credit card debt and tax debt, it might make more sense to pay off the higher-interest credit cards first while setting up a payment plan with the IRS. However, keep in mind that while IRS interest rates are lower, they can also impose additional penalties beyond just interest, which can make the effective rate higher in some cases.

The failure-to-pay penalty is separate from interest and stays at 0.5% per month (up to 25% of the unpaid tax). This rate doesn't change quarterly like the interest rate does. So while your interest will be lower with this change, the penalty percentage stays the same if you can't pay on time. One tip though: If you set up an installment agreement with the IRS, that penalty rate gets cut in half to 0.25% per month instead of 0.5%. Definitely worth doing if you know you can't pay in full by the deadline.

Thanks for explaining! So basically I'll still get hit with the same penalties, but at least the interest portion will be slightly lower. I'll definitely look into setting up an installment agreement this time to get that penalty reduction. Every bit helps when you're trying to dig out of a tax hole.

Do you have a template for this spreadsheet you could share? I've been trying to figure out how to set one up but I'm not sure how to structure it with multiple income sources.

I don't have a shareable template, but here's how I structure mine: I create columns for each income source, then rows for each pay period. I sum these up to get my projected annual income. Then I calculate my taxable income (after standard deduction) and use the tax brackets to estimate my tax liability. I compare this to the total withholding from my pay stubs to see if I'm on track. The key is to update it after each paycheck so you can make adjustments to your withholding if needed. If you're not comfortable with tax brackets, there are IRS withholding calculators online that can help estimate your total tax more accurately.

But don't you need separate bank accounts for each type of business activity even with one LLC? I heard mixing business funds can create problems.

I thought 83(b) elections were only for restricted stock, not stock options? Can you explain how that would work in my ISO situation?

You're absolutely right, and I should have been more precise. 83(b) elections apply to restricted stock awards (RSAs) or early exercises of unvested options, not standard ISO exercises as in your situation. For your situation with vested ISOs at a now-public company, you're dealing with the standard ISO tax rules that others have mentioned. Your main considerations are the timing of exercise relative to AMT implications and holding periods for qualifying dispositions. Apologies for the confusion.

Good catch! Calculation errors on tax forms are a major audit flag. I learned this the hard way with my own ISO exercise last year.

This sounds interesting but a bit complex. Do you need a specialized attorney to set this up? And does it actually reduce your current tax liability significantly or is it more of a long-term strategy?

You definitely need a team including a tax attorney who specializes in charitable planning and an accountant familiar with these structures. The tax benefits are both immediate and long-term. The immediate benefit is a current year tax deduction based on the present value of the future gift to charity, which can be substantial depending on how you structure it. For example, when I placed $500k of appreciated assets into my CRUT, I received a deduction of about $175k in the year I established it, which directly reduced my current tax liability.

I second the S-Corp recommendation! My accountant also had me set a reasonable salary at about 40% of my business income with the rest as distributions. Huge savings on SE tax. Talk to a good CPA about whether that might work for your specific business type.

I run a specialized software development firm focusing on financial services. Currently structured as an LLC taxed as a sole proprietorship. I've heard about the S-Corp strategy but wasn't sure if the administrative overhead was worth it. Sounds like the savings could be substantial though if you're saving $30k just on self-employment taxes. Do you find the added complexity with payroll and additional filings to be a major headache? And did you have to justify your salary-to-distribution ratio to the IRS at all?

That's a really good point about implementation costs for small businesses. Do you think a phased approach would work better? Maybe start with only high-value goods over $10,000 as they suggest for the pilot, then gradually expand if the systems prove manageable?

A phased approach would definitely make more sense. Starting with high-value goods creates a more manageable testing ground since there are fewer transactions to track and the tax revenue per transaction justifies the administrative effort. I think they'd also need to provide free compliance software for small businesses below a certain revenue threshold. South Dakota v. Wayfair actually mentioned the availability of affordable compliance software as one justification for allowing states to impose collection obligations on remote sellers. The same principle should apply here - if compliance is too burdensome, it could face legal challenges.

Good points about imports. I work for a company that imports about 70% of our inventory from overseas, then distributes nationally. Under this system, would we be considered the "producer" state since we're the importer/distributor? Or would all imported goods follow a different rule? Without clarity on this, it seems like there'd be a massive loophole.
