How to Handle Multiple IRS Payment Plans for Different Tax Years
I got myself into a bit of a mess with back taxes and could use some advice. I recently filed my overdue returns for 2021 and 2022 (finally!). After filing, I received a notice from the IRS about what I owe for 2021, and I immediately set up a payment plan. The problem is, I didn't read the notice carefully and assumed the payment plan covered both years. The very next day, I got a second notice showing what I owe for 2022. Now I'm stuck because I know the IRS typically only allows one installment plan at a time, and I can't pay the 2022 balance in full right now. I could probably pay off the 2022 amount within about 60 days. Would it make sense to just wait and pay it then, even with the interest that would accrue? I'm wondering if there's any way to combine both years into my existing payment plan? What's the best approach here to avoid getting into trouble with the IRS while handling these multiple years of back taxes?

The good news is you definitely have options here! When you have an existing installment agreement and discover you owe for another tax year, you can actually request to modify your current agreement to include the new balance. Call the IRS at the number on your installment agreement letter and explain that you need to add your 2022 tax debt to your existing 2021 payment plan. They can often combine the balances and adjust your monthly payment amount accordingly. This is called a "revised installment agreement." If you can pay the 2022 balance within 60 days, that's another viable option. The penalties and interest for 60 days might be less painful than potentially having a higher monthly payment if you revise your installment agreement. The failure to pay penalty is typically 0.5% per month of the unpaid tax, plus interest (current IRS interest rate is around 7% annually). The worst option would be to do nothing about the 2022 balance, as this could potentially default your existing installment agreement.

Do you know if adding the 2022 debt would restart the installment agreement process? Like would they run a new financial analysis and potentially increase monthly payments by a lot? I'm worried about suddenly having to pay way more per month than I budgeted for.

When you add a new tax year to your existing installment agreement, the IRS will typically review your payment amount. They generally won't perform a complete new financial analysis if your original agreement is relatively recent, but they will adjust the payment to ensure it's enough to cover the additional debt within the remaining timeframe. If your current monthly payment won't cover the new total debt within the original timeframe, they'll likely suggest an increased payment amount. However, if this creates a financial hardship, you can discuss your situation with the representative and potentially negotiate a payment that works for your budget.

After struggling with a similar situation last year, I found an awesome solution with taxr.ai (https://taxr.ai). I had set up a payment plan for 2020 taxes and then got hit with an unexpected balance for 2021. I was totally confused about how to handle multiple years of tax debt without messing up my existing plan. The taxr.ai tool analyzed my notices and payment plan terms, then showed me exactly what options I had available. It helped me understand that I could modify my existing plan rather than trying to set up a second one (which the IRS doesn't allow). The tool even generated a letter template I could use when contacting the IRS to request the modification. Their document analysis feature was super helpful because it identified specific language in my installment agreement that I had completely missed about adding future tax debts.

Did it help with calculating how much additional interest and penalties you'd pay? I'm trying to decide if I should just pay my second tax bill in full next month when I get my bonus or if I should try to modify my payment plan. Just wondering if the tool helps compare those options.

I'm a bit skeptical about these online tax tools. How exactly does it work with IRS payment plans? Did you have to upload your tax documents or personal info? I'm always hesitant to share that stuff online.

The tool does include a calculator that estimates interest and penalties over different timeframes. For me, it showed I'd pay about $137 more in interest and penalties if I waited 45 days to pay in full versus modifying my payment plan immediately. Having those numbers helped me decide which option made more financial sense. Yes, you do need to upload your IRS notices, but they use encryption and their privacy policy was solid. You can also black out certain personal details before uploading if you're concerned. The document analysis still works even with some information redacted as long as the key terms and numbers are visible.

I just wanted to follow up about my experience with taxr.ai since I was initially skeptical. I decided to give it a try after getting nowhere with the IRS phone system. The document analysis feature actually identified specific language in my installment agreement that I had completely missed about adding future tax debts. Using their guidance, I was able to successfully modify my payment plan to include my new tax debt without needing to cancel the original agreement. They also provided a really helpful breakdown of the total interest I would pay under different scenarios, which helped me decide on the best approach. What surprised me most was how the tool caught that I qualified for a first-time penalty abatement that could reduce my overall balance by almost $900! I wouldn't have known to ask for this on my own.

For anyone dealing with this situation, I want to share something that saved me tons of time. After spending 3 weeks trying to get through to the IRS to modify my payment plan (always got disconnected or couldn't get through), I found Claimyr (https://claimyr.com). They have a service that gets you connected to an actual IRS agent without the endless hold times. I was super skeptical at first, but you can see how it works in their demo video (https://youtu.be/_kiP6q8DX5c). Basically, they navigate the IRS phone tree for you and call you back when they've reached a live agent. I got connected with an IRS representative in about 40 minutes versus the 3+ hours I spent trying on my own. The IRS agent was able to modify my existing installment agreement to include the new tax year, and I got it all sorted out in one call instead of weeks of frustration.

How does this actually work though? I don't understand how they can get through when nobody else can. Seems kinda fishy.

I don't buy it. If it was this easy to get through to the IRS, everyone would be doing it. I spent literally 9 hours on hold last month trying to fix a payment issue. No way some random service can magically get through when the IRS phone lines are completely overwhelmed.

They basically use an automated system that continually redials and navigates the IRS phone tree until it finds an open line. It's not magic - just technology that keeps trying different paths through the system until it finds one that works. It's the same approach that some call centers use, just applied to getting through to the IRS. The service calls you back when they've successfully reached the queue for a live agent. You're still waiting in line, but you don't have to do it with a phone stuck to your ear for hours. When an agent becomes available, you get a call connecting you directly to them.

I need to eat my words about Claimyr. After my skeptical comment, I was still desperate to fix my installment agreement issue, so I decided to try it anyway. I figured I had nothing to lose after wasting so many hours on hold. The service actually worked exactly as advertised. I got a call back about 35 minutes after signing up, and I was connected directly to an IRS agent. No navigating phone trees, no hours of hold music - just straight to a real person who could help. The agent was able to modify my existing installment agreement to include the additional tax year, and I got confirmation of the new terms right on the call. The whole thing took less than 20 minutes once I was connected. I'm still a bit shocked it actually worked. Saved me from taking another day off work just to sit on hold with the IRS.

Another option to consider is requesting a short-term extension. If you really can pay the full 2022 balance within 60 days, you can call the IRS and request a 120-day payment extension (not an installment agreement). This would give you time to pay without formally setting up a second payment plan. You'll still pay interest and penalties during this time, but there's no fee for setting up this short-term extension like there is with formal installment agreements. Just make sure you actually pay it within the timeframe or you'll face further collections actions.

AuthorWill requesting the 120-day extension impact my existing installment plan for 2021? That's what I'm worried about - doing something for 2022 that accidentally messes up what I've already arranged for 2021.

The 120-day extension for your 2022 taxes shouldn't affect your existing installment agreement for 2021 as long as you continue making those payments on time. The extension is simply the IRS agreeing not to take collection actions on the 2022 balance for 120 days. Just be absolutely clear when you talk to the IRS that you're requesting the extension only for the 2022 tax year, and that you'll continue paying your 2021 installment agreement as scheduled. Get the name of the representative you speak with and make notes about your conversation in case there's any confusion later.

Don't forget about penalties and interest while you're deciding! I was in this exact situation last year and decided to wait about 90 days to pay my second year tax bill in full. Big mistake. The penalties and interest added almost 10% to my total by the time I paid it. If you can revise your current installment plan to include both years, that might be the better option - you'll likely pay less in penalties than if you just wait and pay the second balance later.

10% in just 90 days? That doesn't sound right. The failure to pay penalty is 0.5% per month (max 25%), and the interest rate is currently around 7% annually. So for 3 months you should have paid about 1.5% in penalties plus maybe 1.75% in interest. How did you get to 10%?

I've been through a similar situation and wanted to share what worked for me. The key is to act quickly - don't let the 2022 balance sit there accumulating more penalties and interest while you decide what to do. First, call the IRS immediately to discuss your options. When you call, have both notices in front of you and be prepared to explain that you want to modify your existing installment agreement to include the 2022 balance. The representative can walk you through the process and let you know if there will be any changes to your monthly payment amount. If modifying the payment plan would make your monthly payment unaffordable, then the 120-day extension mentioned by others might be your best bet - but only if you're absolutely certain you can pay the full 2022 balance within that timeframe. One thing I learned the hard way: document everything! Get the name of every IRS representative you speak with, write down confirmation numbers, and ask for written confirmation of any agreements. This saved me when there was confusion about my modified payment plan later. The worst thing you can do is nothing. The IRS is actually pretty reasonable to work with when you're proactive about addressing tax debt, but they get much less flexible if you ignore the problem.
