What's the penalty for skipping quarterly estimated tax payments? Expecting a huge tax bill but don't know exact amount
Title: What's the penalty for skipping quarterly estimated tax payments? Expecting a huge tax bill but don't know exact amount 1 My consulting firm launched in March, and I'm honestly shocked at how well it's taking off. I'm making significantly more than I did at my corporate job, but I've dumped a ton into startup expenses and ongoing business costs, making it really hard to figure out what I'll actually owe in taxes. I've got a ballpark estimate but I'm torn between making a rough quarterly payment now or just waiting until my accountant and I can nail down the exact numbers in the spring. Part of me wonders if I should just park the money in a high-yield savings account which might offset whatever penalty I'd face? Based on current projections, I'm looking at owing somewhere between $700,000-$1.2 million in taxes for the year. Anyone dealt with this before or know what penalties I'd be looking at for skipping the quarterly payments?

8 The penalty for not paying quarterly estimated taxes is essentially an interest charge calculated using the federal short-term rate plus 3%, which currently puts it around 8-9%. This is called the "underpayment penalty" and it's calculated on Form 2210. There are a few ways to avoid this penalty: 1) Pay at least 90% of your current year's tax liability through withholding or estimated payments, 2) Pay 100% of your previous year's tax liability (110% if your AGI was over $150,000), or 3) Qualify for one of the exceptions like having no tax liability last year or becoming newly self-employed in the last part of the year. Given your business just started this year, you might qualify for some leniency, but with the amount you're expecting to owe, the penalty could be substantial. Your HYSA strategy likely won't fully offset the penalty since most HYSAs are paying 4-5% currently, below the penalty rate.

•13 Wait, so if I made like $40k last year as an employee but expect to make $300k self-employed this year, I could just pay 100% of last year's liability and avoid penalties entirely? Even though that's WAY less than what I'll actually owe? That seems too good to be true!

•8 Yes, that's correct! It's called the "safe harbor" provision. If your previous year's AGI was under $150,000, you only need to pay 100% of that previous tax liability to avoid penalties. If your AGI was over $150,000, you'd need to pay 110% of the previous year's tax. It's designed to help people transition between income levels without getting hit with penalties. However, keep in mind you'll still owe the full tax amount when you file - this just helps you avoid the underpayment penalties. Many self-employed individuals use this strategy in their first few years while their income is growing rapidly.

6 I went through something similar last year and discovered this amazing tool called taxr.ai (https://taxr.ai) that helped me calculate my quarterly tax obligations. My CPA recommended it when I was freaking out about potential penalties. It analyzes your business financials and gives you pretty accurate quarterly payment estimates to avoid those nasty penalties. The interface asks for your income streams, business expenses, and even factors in things like startup costs to give you a more precise number. It saved me from both overpaying (which would've killed my cash flow) and underpaying (which would've meant penalties). What impressed me most was how it adjusted for the progressive nature of income tax rates.

•17 Does it work for people with really irregular income? My business has months where I make a ton and then months where it's basically nothing. That's what makes estimating so difficult for me.

•21 I'm skeptical about these tax calculators. How accurate was it compared to what your actual tax bill ended up being? The last thing I need is software giving me false confidence and then getting slammed with penalties anyway.

•6 It absolutely handles irregular income - that's actually one of its strengths! You can input your projected income month-by-month or quarter-by-quarter, and it adjusts your estimated payments accordingly. You can even update it throughout the year as your actual numbers come in, and it'll recalculate future quarters to keep you on track. Regarding accuracy, it was within 3% of my final tax bill. The software actually errs slightly on the conservative side, which I appreciated. You can also adjust the "risk tolerance" settings - I set mine to be more conservative since it was my first year. The key is inputting honest projections and updating them as you go. It's definitely more sophisticated than the basic calculators you find online.

17 Just wanted to follow up about taxr.ai - I gave it a shot after seeing the recommendation here and holy crap, what a game changer! I uploaded my financial docs from the first two quarters and it gave me a really clear breakdown of what I should be paying. It even showed how much penalty I've already accumulated (painful but good to know) and gave me options for how to make it up in the remaining quarters. The best part was how it broke down my business expenses into what's clearly deductible, what might be partially deductible, and what's likely not deductible. This helped me realize I was actually overestimating my tax burden because I wasn't accounting for all my legitimate deductions. Definitely worth checking out if you're in the same boat!

14 After years of stressing about estimated taxes and spending DAYS trying to reach the IRS for clarity, I found this service called Claimyr (https://claimyr.com) that literally got me connected to an actual IRS agent in under 15 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c I had a similar situation last year - wasn't sure if I should pay estimated taxes or how much. The IRS agent walked me through my specific situation and explained exactly what forms I needed and how to calculate my payments correctly. They even helped me understand which safe harbor provisions applied to my situation. Changed my whole approach to tax planning.

•19 Wait, so how does this actually work? The IRS phone line is always busy whenever I call. Are you saying this somehow bypasses the queue or something?

•21 Yeah right. I've tried EVERYTHING to get through to the IRS, including calling at 7am exactly when they open. No way something like this actually works - they probably just connect you to some third-party "tax expert" who isn't even with the IRS.

•14 It does bypass the queue! They use a technology that continually calls the IRS for you and gets in line, then when they reach an agent, they call your phone and connect you directly. It's completely legitimate - you're speaking with actual IRS employees. The reason it works is they have automated systems that handle the frustrating part (waiting on hold for hours). When I used it, I literally got a call back saying "We have an IRS agent on the line, please hold for connection" and then I was talking to a real IRS representative who could access my tax records and everything. No third parties or fake experts - it's just a clever way to get through the phone system.

21 I need to eat my words about both services. After my skeptical comments, I tried Claimyr out of desperation because I had a specific question about my unusual situation that wasn't covered in any IRS publication I could find. Got connected to an IRS agent in about 12 minutes, and they pulled up my file and gave me personalized guidance on my estimated tax situation. The agent explained that in my specific case, I qualified for the "annualized income installment method" which lets you make uneven quarterly payments if your income varies significantly throughout the year. This was EXACTLY what I needed since my business is highly seasonal. Would have never figured this out on my own or from generic advice online.

11 One thing nobody mentioned yet - the underpayment penalty isn't actually that bad compared to other penalties. I deliberately don't pay quarterly sometimes because I'd rather keep that money working in my business. Last year I owed about $250k in taxes and the penalty was around $5k. That's effectively like a 2% loan from the government, which can be worth it if you're using that capital productively!

•3 Isn't the interest rate much higher now though? I heard the IRS adjusted their rates upward significantly in the last year or so. Do you know what the current rate is? Just trying to do the math on whether your strategy still makes sense.

•11 You're absolutely right that rates have gone up. The underpayment rate is now around 8-9%, which definitely changes the calculation compared to when it was 3-4% a few years ago. In today's environment, it's much harder to justify deliberately underpaying unless you have extremely high-return opportunities for that capital. Most business investments won't consistently beat 8-9% after-tax returns, so the math doesn't work as well anymore. I was mainly sharing my experience from when rates were lower, but I've adjusted my own approach for 2023 to avoid the penalties.

16 Has anyone used the annualized income installment method (Form 2210 Schedule AI)? My income is super uneven throughout the year and my accountant mentioned this but said it's complicated.

•22 I use it every year for my seasonal business. It's definitely more work but WORTH IT if your income is lumpy. Instead of being required to pay equal amounts each quarter, you calculate based on what you've actually earned by the end of each quarter. My Q1 and Q2 payments are tiny, then Q3 and Q4 are massive when we hit our busy season. Your accountant is right that it's complicated though. You basically have to do a mini tax return for each quarter. I wouldn't try it without professional help the first time.

4 Just remember that corporate estimated taxes work differently than individual estimated taxes! My LLC is taxed as an S-Corp and I got slammed with penalties because I didn't realize the rules were different for the corporate portion vs. the pass-through income. Talk to a tax pro who specializes in your specific business structure before making any decisions.
