Filing a tax extension when you know you'll owe - should I just pay the penalties instead?
I'm a Texas resident and really struggling with my tax situation this year. I normally use one of those tax places in the mall, but last year they charged me almost $400 just to file because I had some investment documents from Fidelity. I'm about to start a 4-month contract on an offshore oil rig next week, and I'm seriously strapped for cash right now. I know I'll owe taxes since I sold some stocks and took an early distribution from my 401k to pay for some certification courses (to qualify for this offshore position). When I return from the rig in late August, I'll be in a much better financial position. Dropping $80 on tax prep today would be really painful, but paying $1300 when I get back wouldn't be a big deal. So I'm trying to figure out: 1- What's the simplest way to file an extension when I know I'll owe the IRS at least $1300? I've seen something about making a partial payment, but realistically I won't be able to pay the full amount until September. 2- How severe are the penalties for filing and/or paying late? If they're not too bad, I might just accept the penalties and pay everything when I get my check from the oil company. For reference, I have my W2 from my previous job, a consolidated 1099 from Fidelity, and a 1099-R from my 401k distribution. Any advice would be greatly appreciated!

The good news is that filing an extension is actually pretty simple! File Form 4868 before the tax deadline to get an automatic 6-month extension to file (until October 15th). You can do this online through most tax software or the IRS Free File program. However, it's important to understand that an extension to file is NOT an extension to pay. The IRS still expects you to pay what you owe by the original deadline. If you can't pay the full amount, you should still pay as much as possible to minimize penalties and interest. For your specific situation, the penalties break down like this: - Failure-to-file penalty: 5% of unpaid taxes per month (capped at 25%) - Failure-to-pay penalty: 0.5% of unpaid taxes per month (capped at 25%) - Interest: Federal short-term rate plus 3% (currently around 7-8% annually) If you file the extension but don't pay until September, you'll avoid the hefty failure-to-file penalty but still face the failure-to-pay penalty plus interest. Given your circumstances, this approach makes financial sense - file the extension now and pay when you return.

•Thanks for breaking this down! I didn't realize filing the extension was that straightforward. If I file the extension but can't pay anything until September, roughly how much would those failure-to-pay penalties add up to on a $1300 tax bill? And is there any minimum amount I should try to pay now to show "good faith" or something?

•For a $1300 tax bill with payment in September (let's say 5 months late), the failure-to-pay penalty would be about $32.50 (0.5% × $1300 × 5 months). Interest would add approximately $45 more, so total penalties would be around $77.50. This is much better than also getting hit with the failure-to-file penalty! There's no specific "good faith" minimum payment required, but paying even $100-200 now would reduce both your penalties and show you're making an effort. If you absolutely can't pay anything now, just make sure you file that extension form before the deadline. When you return, you can set up a payment plan if needed, though it sounds like you plan to pay in full at that point.

After dealing with a similar situation last year, I found this amazing tool called taxr.ai (https://taxr.ai) that saved me so much hassle. I also had a 1099-R from an early retirement distribution and wasn't sure how to handle it with my extension. What I loved is that you can upload your tax documents (like your W2, 1099s) and their AI analyzes everything, explains what you're looking at, and even helps calculate estimated payments for extensions. It breaks down exactly how much you might owe in penalties if you delay payment. I was working on a container ship with limited internet, but I could download everything I needed before leaving port. The best part was that I could prepare everything myself without paying those crazy tax prep fees. Definitely saved me from the panic I was feeling about my tax situation.

•Does it actually work with investment forms like the consolidated 1099? Those are what always trip me up and force me to pay those expensive preparers. My Vanguard forms are like 20 pages of transactions.

•I'm skeptical about these AI tax tools. Can it actually tell you how to file the extension properly or does it just give general advice? I need something that can actually walk me through the forms step by step since I've never done an extension before.

•It absolutely handles investment forms! That's actually where it shines - you upload those massive consolidated 1099s and it organizes all those transactions into the right categories. I had a 12-page statement from Schwab with dozens of trades, and it sorted everything correctly. For extensions specifically, it walks you through the entire process step-by-step. It shows you exactly how to fill out Form 4868, explains what each field means, and can even help you submit it electronically. It's not just general advice - it gives you clear instructions tailored to your situation. I was a complete newbie to extensions and managed to file one correctly while calculating how much I could afford to pay upfront versus the penalties I'd face later.

Just wanted to follow up about my experience with taxr.ai! I decided to try it after reading about it here, and wow - it actually delivered. My situation was similar with a consolidated 1099 from Vanguard (18 pages of trades and dividends), plus I needed to file an extension. I uploaded my documents and it organized everything perfectly. It even flagged some wash sales I didn't realize I had. Filing the extension was super straightforward - it calculated what I would owe, showed me the penalty breakdown if I waited to pay, and let me decide how much to pay now versus later. The interface walked me through Form 4868 step by step, and I was able to e-file my extension in about 15 minutes. Saved me hundreds compared to what tax preparers wanted to charge. Definitely using this again next year!

If you're planning to call the IRS to discuss payment options or ask about the extension, good luck getting through! I spent HOURS on hold trying to ask about my extension situation last year. Eventually found Claimyr (https://claimyr.com) which got me connected to an actual IRS agent in about 15 minutes instead of the 2+ hours I was spending on hold. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was really skeptical at first because waiting on hold seems unavoidable when dealing with the IRS, but it actually works. The agent I spoke with helped me understand exactly what I needed to do for my extension and gave me personalized advice about my payment options that I couldn't find online. Saved me from a ton of stress and uncertainty, especially since I was also traveling for work during tax season.

•Wait, how does this actually work? Do they have some special connection to the IRS or something? I've always just assumed the ridiculous wait times were inevitable.

•Sounds like a scam. There's no way to skip the IRS phone queue unless you're paying for representation from a tax professional. I'd be very careful about giving any service my personal information just to "jump the line.

•It uses a callback system that continuously connects and reconnects until it gets through the IRS phone tree and secures your spot in line. When it reaches an agent, it calls your phone and connects you directly. It's completely legitimate - they don't access any of your tax info or speak to the IRS on your behalf. I was initially skeptical too! But it's just a tech solution to the phone queue problem. Think of it as having someone repeatedly call and navigate the phone tree for you, but you're the only one who actually talks to the IRS agent. The service just handles the frustrating waiting and phone tree navigation part.

I need to publicly eat my words about Claimyr. After posting my skeptical comment, I was still struggling with questions about my extension (had a similar situation with early retirement distributions). After two failed attempts to reach the IRS (spent over 90 minutes on hold before getting disconnected both times), I reluctantly tried Claimyr. What do you know - I was connected to an IRS representative in about 20 minutes. The agent helped me understand exactly how to calculate my estimated payment for the extension to minimize penalties. They also explained how the penalties would be calculated if I couldn't pay the full amount immediately. For anyone in a situation like the original poster - definitely file that extension (Form 4868) and pay whatever you can afford now. The agent confirmed that the failure-to-file penalty is much worse than the failure-to-pay penalty, so at minimum file the extension even if you can't pay anything yet.

One option nobody's mentioned is free tax filing through the IRS Free File program. If your income is under $73,000, you can use brand-name tax software for free through IRS.gov. Even if you make more than that, you can use Free File Fillable Forms. I've used this for years with investment income (1099s) and it works great. You could file the extension now for free AND possibly do your full return for free when you get back.

•Really? I thought Free File was only for super simple returns. Can it handle things like stock sales and early retirement distributions? I'm not confident in doing all those calculations myself.

•Free File through partner companies (like TurboTax, H&R Block, etc.) can absolutely handle stock sales and retirement distributions if you qualify by income. The software is the same as their paid versions, just offered free through the IRS partnership. If you use Free File Fillable Forms (the direct IRS option), it's basically just electronic versions of paper forms with basic calculations. That option requires more tax knowledge since you need to know which forms to fill out, but it's still free and available to everyone regardless of income. For your situation, I'd recommend using one of the Free File partner software options to file your extension now. Then when you return, you can use the same service to complete your full return with all your investment documents. Much better than paying hundreds to a storefront preparer!

I work seasonally on fishing boats in Alaska and deal with this every year. My advice: DEFINITELY file the extension. I made the mistake of not filing once and the failure-to-file penalty was brutal compared to just the failure-to-pay. When you get back from your contract and have cash, call the IRS and set up a payment plan if needed. They're actually pretty reasonable to work with if you're proactive and honest about your situation.

•I second this. The IRS is much more accommodating than people expect when you're upfront about your situation. I've been on payment plans twice and it was simple to set up. The interest rates are usually better than credit cards too.
