Filing late - confused about which address to send 2020 tax return to

I'm finally getting around to submitting my 2020 form 1040 by mail (I know, I'm way behind). In the 1040 instructions booklet, which is like 100+ pages long, it says something specific about mailing addresses for Pennsylvania residents, but then I got completely lost. There seems to be different addresses depending on whether you're enclosing payment or not, and then different addresses based on which state you're in. I live in Pittsburgh and I will be enclosing a payment with my return. I tried searching online but found conflicting information - some sites say use the Cincinnati service center, others mention the Kansas City location. Does anyone know for sure which IRS address I should be using to send my 2020 form 1040 for Pennsylvania? I don't want to make my late filing situation worse by sending it to the wrong place and having it get lost in the system for months.

The IRS has specific mailing addresses based on your state and whether you're including a payment. For Pennsylvania residents sending a Form 1040 with a payment, you should use: Internal Revenue Service P.O. Box 802501 Cincinnati, OH 45280-2501 If you weren't including a payment, you'd use a different address, which is why you're seeing varied information. Make sure you're using certified mail with tracking so you have proof of when you sent it. Also, be aware that since you're filing a 2020 return now, you'll face penalties for late filing and payment - typically 5% of unpaid taxes per month for the failure-to-file penalty (up to 25%), plus interest charges. Remember to include a check or money order with your payment voucher (Form 1040-V) if you're sending payment. And write "2020 Form 1040" plus your SSN on the payment.

Thanks for this info! Quick follow-up question: does the IRS still process refunds for late returns like this? I'm in a similar situation but I'm actually owed a refund for 2020. Also, do you know how long processing typically takes for these super late paper returns?

0 coins

Yes, the IRS will still process refunds for late returns, but there's a deadline. You have three years from the original due date to file and claim a refund. For 2020 returns (which were due May 17, 2021 due to COVID extensions), you have until May 17, 2024 to claim your refund. After that date, you lose your refund. Processing times for paper returns are significantly longer than e-filing, especially for prior year returns. Currently, expect 6-8 months for processing paper returns from prior years, though it could be faster or slower depending on IRS backlog conditions.

After struggling with the exact same issue (late 2019 return), I discovered this amazing service called taxr.ai (https://taxr.ai) that saved me so much frustration. I was about to mail my return to the wrong address until I uploaded my documents there and their system flagged the correct mailing address based on my situation. It also identified some deductions I completely missed that ended up reducing what I owed by over $700! They have this document analysis tool that reviews your tax forms before you submit them and checks for errors or missing opportunities. Seriously wish I'd known about this years ago. It's like having a tax pro review your stuff but without the awkward meeting.

Can this taxr.ai thing help if I've already prepared my return using TurboTax? Or do I need to start from scratch with their system? I've got my 2020 return printed out and ready to mail but now I'm worried I might have missed something.

I'm a bit skeptical about these tax services. How does it actually work? Do real humans review your documents or is it just some algorithm? I'm always nervous about uploading my tax documents to random websites.

You can absolutely use it with returns you've already prepared! Just upload your completed forms and their system will analyze what you've done and flag any potential issues or missed opportunities. No need to start over - it works as a review layer on top of whatever you've already done. Their system uses AI to analyze the documents, but it's specifically designed for tax form analysis. They have strong encryption and security protocols - I was initially hesitant too, but they explain on their site how they protect your data. They don't store your documents after analysis, which was important to me.

Just wanted to update - I decided to try taxr.ai before mailing my 2020 return and wow, I'm glad I did! Not only did it confirm the correct mailing address for my situation, but it actually found a mistake in how I calculated my home office deduction. Apparently I was way too conservative and missed out on about $1,200 in deductions! The document review took less than 10 minutes and highlighted everything in a really easy-to-understand format. I was able to make the corrections before sending it off. Definitely recommend if you're filing late returns and want to make sure everything is correct!

If you're worried about your late filing being processed quickly, I highly recommend using Claimyr (https://claimyr.com) to actually speak with an IRS agent about your situation. I was in the same boat with a late 2018 return and spent WEEKS trying to get through to the IRS phone line without success. Claimyr got me connected to an actual IRS representative in under 45 minutes when I had been trying for days on my own. The agent was able to confirm my return was received and give me a timeframe for processing. You can see how it works here: https://youtu.be/_kiP6q8DX5c It's ridiculous how hard it is to actually speak with someone at the IRS, especially when dealing with late filings where you need confirmation everything's been received properly.

Wait, how does this service actually work? Are they just calling the IRS for you? Why would that be any faster than me calling directly? I've been trying to get through for weeks about my late filing.

0 coins

This sounds like complete BS. Nobody can magically get through to the IRS faster. They probably just keep you on hold themselves and then transfer you when they finally get through, charging you for the privilege. I'll believe it when I see it.

They use an automated system that navigates the IRS phone tree and waits on hold for you. When an agent finally picks up, you get a call connecting you directly to that agent. It's not magic - just technology that handles the frustrating wait time so you don't have to sit with a phone to your ear for hours. They're actually very transparent about how it works. It's still the same IRS queue everyone else is in, but their system does the waiting instead of you. I was skeptical too, but when I was connected to an actual IRS agent after trying unsuccessfully for days, I became a believer. The time saved was absolutely worth it for me.

I stand completely corrected about Claimyr. After my skeptical comment, I decided to try it myself since I needed to ask about my own late filing situation. It actually worked exactly as advertised. I got a call back in about 30 minutes connecting me directly to an IRS agent who helped confirm my payment had been received but my return was still in processing. The agent also gave me specific information about the penalties I'd be facing and how to request an abatement based on my situation. Getting actual answers instead of guessing was such a relief. Sometimes it's worth being proven wrong!

One other thing to consider when filing super late returns - if you're owed a refund, the IRS won't pay interest on it beyond the 45-day processing window following the original due date. But if you OWE money, they absolutely charge interest from the original due date until you pay in full. Also, make sure you're considering how this late 2020 return might affect any credits you claimed in subsequent years, especially pandemic-related credits that were expanded for 2020. Sometimes filing a late return can create a domino effect requiring amendments to later years.

Since I'm sending in a payment with my late return, would you recommend I pay the amount I calculated plus some extra to cover potential penalties? Or should I just pay exactly what's shown on my return and wait for them to bill me for the rest?

0 coins

I'd recommend paying somewhat more than what you calculated - perhaps 25-30% more to account for the failure-to-file penalty (5% per month up to 25%) plus interest. The IRS will eventually send you a notice showing the exact penalties and interest, and they'll either refund any overpayment or bill you for any remaining balance. When you make the payment, clearly indicate it's for "2020 Form 1040" and include your SSN on the check. This helps ensure it gets applied to the correct tax year. If you've calculated your tax correctly, the extra amount should cover most or all of the penalties and interest, which helps avoid additional interest accruing while you wait for the bill.

Does anyone know if the IRS is still processing paper returns normally? I heard they had massive backlogs during COVID and I'm worried my late return will get stuck in some warehouse for years. Should I attach some kind of note explaining why I'm filing so late, or do they not care about that?

0 coins

The IRS has mostly worked through their COVID backlog for paper returns, but they're still slower than pre-pandemic times. I filed a paper 2019 return last spring and it took about 4 months to process. No need to include a note explaining why you're late - they don't factor that into processing. They just apply the standard penalties.

Actually adding a statement can help if you're requesting a penalty abatement! If you have a reasonable cause (serious illness, natural disaster, etc.), include Form 843 and a letter explaining your circumstances. The IRS can waive penalties (but not interest) if you have good reason.

For Pennsylvania residents filing 2020 Form 1040 with payment, the correct address is indeed the Cincinnati service center that Javier mentioned. However, I'd strongly recommend double-checking this on the current IRS website since mailing addresses can occasionally change. One thing I haven't seen mentioned yet - since you're filing so late, you might want to consider requesting penalty relief if you have reasonable cause. The IRS can waive failure-to-file and failure-to-pay penalties (though not interest) in certain circumstances like serious illness, natural disasters, or other situations beyond your control. You'd need to include Form 843 (Claim for Refund and Request for Abatement) with your return if you want to request this. Also, make sure you're using the 2020 version of Form 1040 and its instructions, not the current year's form. You can download it from the IRS website under "Prior Year Products." The tax law and forms do change from year to year, so using the correct year's forms is important. Definitely use certified mail with return receipt requested so you have proof of mailing and delivery!

This is really helpful advice about Form 843 for penalty relief! I had no idea that was even an option. Quick question - if I'm filing this late because I was dealing with a serious medical issue in 2020-2021, what kind of documentation would I need to include with Form 843? Like medical records or just a doctor's note? I'm worried about sending too much personal health information through the mail.

0 coins

For medical situations, you typically don't need to send detailed medical records - a letter from your doctor or medical professional explaining that you had a serious illness during the relevant time period that prevented you from meeting your tax obligations is usually sufficient. The letter should include: - The approximate dates you were affected - A general description that the condition prevented you from handling tax matters (without going into specific medical details) - The doctor's contact information and signature You can also include a brief personal statement explaining how the medical issue specifically prevented you from filing on time. The IRS understands privacy concerns, so they don't expect you to divulge your complete medical history - just enough documentation to show reasonable cause. Keep copies of everything you send, and consider sending the Form 843 request separately from your tax return if you're concerned about processing delays. That way your return can be processed while they review your penalty abatement request separately.

Just to add another perspective - if you're really concerned about your late 2020 return getting lost in the mail or taking forever to process, you might want to consider hiring a tax professional to help you navigate this situation. Many CPAs and enrolled agents have direct lines to IRS practitioner hotlines that can be much more efficient than trying to get through as an individual taxpayer. A tax pro can also help you calculate the exact penalties and interest you'll owe, determine if you qualify for any penalty relief, and ensure your return is prepared correctly to avoid any processing delays or audit flags. Yes, it costs money, but if you're dealing with a complex situation or significant tax liability, the peace of mind and potential savings from their expertise often outweigh the fees. Also, for future reference - the IRS offers payment plans if you can't pay your full tax liability at once. Even for late returns, you can set up an installment agreement either online or by including Form 9465 with your return. This can help manage the financial impact of those accumulated penalties and interest.

This is excellent advice about getting professional help! I'm in a similar situation with multiple late returns (2020 and 2021) and was feeling completely overwhelmed trying to figure out penalties, interest calculations, and whether I qualify for any relief programs. The practitioner hotline access is something I hadn't considered - it makes sense that tax professionals would have better ways to get through to the IRS than regular taxpayers calling the main number. At this point, paying for professional help might actually save me money in the long run if they can help me avoid mistakes or find deductions I'm missing. Do you happen to know if CPAs typically charge extra for dealing with late/prior year returns, or is it usually just their standard preparation fee? I'm trying to budget for this properly since I'm already facing penalties and interest on top of what I originally owed.
