Need street address for IRS Department of Treasury in Kansas City, MO to efile my taxes

Wait, are you sure that's right? I thought the Kansas City one was on Summit Street? My aunt worked for the IRS and I swear she mentioned a different address. Also, does it matter if the 1099-INT is from the Treasury Department specifically and not the IRS? Or are they basically the same thing for tax purposes?

You might be thinking of the IRS office in Kansas City, KS which is located at 6717 Shawnee Mission Parkway. However, the main IRS processing center for the Department of Treasury in Kansas City, MO is definitely at 333 W. Pershing Road. The Treasury Department and IRS are related - the IRS is a bureau of the Department of Treasury, so for tax filing purposes you'd use the IRS address when the form comes from the Treasury Department. The software is just looking for a valid physical location to complete the form.

Does it actually work with government forms like 1099-INT? Most tools I've tried get confused with anything from the IRS/Treasury and give generic answers. How specific was the address info it gave you?

I'm confused about how this works. Do you have to pay for it? And is it secure? I'm always nervous about uploading my tax docs to random websites. No offense, just cautious with financial stuff.

It absolutely works with government forms - that's actually where it shines because official forms have standard formats the system recognizes instantly. It gave me the complete address with the correct format: Department of Treasury, Internal Revenue Service, 333 W. Pershing Road, Kansas City, MO 64108. Regarding security, I had the same concerns initially! They use bank-level encryption and don't store your documents after analysis. I've been using it for two tax seasons now without any issues. They offer both free and premium options depending on how many documents you need analyzed, but the basic address verification worked with their free tier for me.

How does this actually work? Like, they just sit on hold for you? Seems too good to be true - the IRS hold times are BRUTAL this filing season.

Sounds like a scam to me. Why would I pay someone else to call a free government service? The IRS will eventually answer if you're patient. And how do they even get your call back number to the IRS agent? The IRS doesn't take "please call this other person" requests.

They use an automated system that maintains your place in the queue and monitors for when a human agent is about to answer. When that happens, they call you and connect you directly to the IRS agent. It's not someone physically waiting on the phone for you. I was super skeptical too, but the reality is the IRS is severely understaffed. Average wait times are 90+ minutes this filing season. I literally couldn't stay on hold that long during work hours. They don't give your number to the IRS - they connect the calls together when an agent answers. It's basically creating a three-way call but then they drop off once you're connected.

Mailing takes FOREVER to process though. I mailed my return last year and it took 4 months to get my refund. E-filing usually gets you your money in like 2-3 weeks. Plus mailing costs money and requires a trip to the post office.

That's a valid point about the processing time. When I mail mine, I've mentally prepared to wait 8-12 weeks for processing, so the timing doesn't bother me much. I actually find the post office trip quite simple - I just use a pre-addressed envelope and certified mail to have tracking. The peace of mind knowing it's been delivered is worth the $5 or so it costs me. But I understand that for larger refunds, waiting those extra weeks can be a significant financial consideration.

Yep, they definitely have multiple addresses. The main processing center is at Pershing Road, but they also have operations at 33 W. 11th Street in KC, and some specialized divisions at other locations. Depending on which department issued your 1099-INT, it might have come from a different physical location.

This is really helpful! I'm actually dealing with this exact issue right now and it's been so frustrating. I've been going back and forth with my tax software for hours. Quick question - how do you know which 9-digit ZIP code to use? My 1099-INT just shows "Kansas City, MO" without any ZIP code at all. Is there a way to figure out if it should be 64108-2203 or 64108-2223? I don't want to guess wrong and have my e-filing get rejected again. Also, when you say "exactly as it appears on the form" - mine says "DEPT OF TREASURY INTERNAL REVENUE SERVICE" all in caps. Should I enter it exactly like that, or is it okay to use normal capitalization?

For the ZIP code, you can usually find the correct 9-digit version by looking at the return address on the envelope your 1099-INT came in, if you still have it. If not, I'd recommend starting with 64108-2203 since that's the most common one for Treasury Department forms. If that gets rejected, then try 64108-2223. As for the capitalization, most tax software will accept either format, but to be safe I'd enter it exactly as shown on your form: "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps. The software is looking for an exact match, so keeping the original formatting reduces the chance of rejection. One more tip - if you're still having trouble after trying both ZIP codes, some people have had success just using "INTERNAL REVENUE SERVICE" as the payer name instead of the full Department of Treasury title. The key is that the software recognizes it as a legitimate government entity.

For the ZIP code, try 64108-2223 first - that's what the IRS agent confirmed when I called through Claimyr earlier. If that gets rejected, then try 64108-2203. Most tax software will give you a specific error message if the ZIP is wrong, so you'll know pretty quickly. As for the capitalization, you can use normal capitalization. The tax software usually standardizes that automatically. So "Department of Treasury Internal Revenue Service" should work fine even though your form shows it in all caps. The important thing is getting the name and address components right, not the exact formatting. One more tip - if you're still getting rejections after trying both ZIP codes, some people have had success by calling their tax software's support line. They often have a database of common government addresses that work with their specific system.

Great questions! For the ZIP+4 code, you can usually find the correct one by looking at the postmark or return address on the envelope your 1099-INT came in - that often has the full 9-digit code. If you don't have the envelope anymore, I'd recommend starting with 64108-2203 since that's the most common one for Treasury Department forms from that location. Regarding the capitalization, most tax software will accept either format, but to be safe I'd enter it exactly as shown on your form: "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps. The software is looking for an exact match, so staying true to what's printed is usually your best bet. If the first ZIP+4 doesn't work, just try the other one (64108-2223). One of them should definitely get your e-filing accepted!

Great questions! For the ZIP code, you can usually determine which one to use based on the type of form. From what I've seen, 1099-INT forms typically use 64108-2203, while some other Treasury forms use 64108-2223. If you're not sure, try 64108-2203 first since that's more common for interest-related documents. Regarding the capitalization - most tax software is flexible about caps vs. normal text, so you can enter it as "Dept of Treasury Internal Revenue Service" or "Department of Treasury Internal Revenue Service" rather than all caps. The software usually standardizes the formatting when it submits anyway. If you're still having trouble after trying these variations, you might want to check if your tax software has a "lookup" or "search payer" feature. Many programs have databases of common payers (including government entities) that can auto-fill the correct address format. That might save you from having to guess at the exact formatting they want.

Great questions! For the ZIP code issue, you can usually find the correct 9-digit code by looking up the specific IRS facility on the IRS website or calling their main number. However, from what I've seen in this thread and my own experience, 64108-2223 tends to work for most Treasury Department 1099-INT forms, while 64108-2203 is more common for other IRS correspondence. As for the capitalization, most tax software will accept either format. I'd recommend trying it exactly as shown on your form first ("DEPT OF TREASURY INTERNAL REVENUE SERVICE"), and if that gets rejected, then try the more standard format ("Department of the Treasury - Internal Revenue Service"). The e-filing system is usually more concerned with having the complete address and correct ZIP+4 code than the exact capitalization. If you're still having trouble after trying both ZIP codes, that Claimyr service someone mentioned earlier might be worth it to get direct confirmation from an IRS agent.

Good questions! For the ZIP code, you can usually find the correct 9-digit version by looking up the IRS Kansas City address on the USPS website or calling them directly. In my experience, 64108-2223 tends to be more commonly used for general Treasury/IRS correspondence, but it can vary by department. Regarding the capitalization - most tax software will accept either format, but I'd recommend entering it exactly as shown on your 1099-INT to be safe. So if yours shows "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps, go with that. The software is looking for an exact match to what's on the official form. If you're still having trouble after trying both ZIP codes, you might want to contact your tax software's support team. They often have a database of common government payer addresses and can tell you the exact format their system expects for IRS Kansas City forms.

Great questions! For the ZIP code, you can usually find the correct 9-digit version by looking up the specific IRS facility on the USPS website or calling the IRS directly. However, most tax software will accept either 64108-2203 or 64108-2223 for the Kansas City processing center - I've seen both work successfully. Regarding the capitalization, you should enter it exactly as it appears on your 1099-INT form. If it says "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps, enter it that way. Tax software often does exact matching on payer names, so any variation (even capitalization) can cause rejection issues. One tip: if you're still getting rejections, try entering just "INTERNAL REVENUE SERVICE" as the payer name instead of the full department name. Sometimes the longer version causes formatting issues in certain tax programs. The IRS will still process it correctly since they can match it to your 1099-INT based on the EIN and other details.

Great questions! For the ZIP code, you can usually find the correct 9-digit version by looking up the specific IRS facility on the IRS website or calling their main number. However, most tax software will accept either 64108-2203 or 64108-2223 for Kansas City Treasury/IRS addresses - they both route to the same processing center. If you want to be extra safe, try 64108-2203 first since that's the most commonly used extension for the main processing center at 333 W. Pershing Road. For the capitalization issue - most tax software is flexible about that. You can enter it as "Department of Treasury Internal Revenue Service" or "DEPT OF TREASURY INTERNAL REVENUE SERVICE" and either should work. The software typically standardizes the formatting when it transmits to the IRS anyway. I'd personally go with normal capitalization since it's easier to read and verify for accuracy. If you're still getting rejections after trying these formats, it might be worth double-checking that all the other numbers (EIN, account numbers, interest amounts) match your form exactly. Sometimes the address isn't actually the problem!

Great questions! For the ZIP code, you can usually find the correct one by looking at the postmark on the envelope your 1099-INT came in, or check the IRS website's office locator for Kansas City. In most cases, 64108-2203 works for general tax document processing, but if that gets rejected, try 64108-2223. As for the capitalization, most tax software can handle either format, but I'd recommend entering it exactly as it appears on your form first - so "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps. If that doesn't work, then try the more standard format "Department of Treasury Internal Revenue Service" with normal capitalization. The e-filing system is looking for an exact match with their database, so starting with the exact format from your form gives you the best chance of success on the first try. You can always adjust if it gets rejected!

Great questions! For the ZIP code, you can usually find the correct 9-digit version by looking up the IRS Kansas City processing center on the USPS website or calling your tax software's support line - they often have a database of common government addresses with the full ZIP+4 codes. In my experience, most tax software is flexible with capitalization, so you can use normal capitalization instead of all caps. However, if you're still getting rejections after trying the standard format, then try entering it exactly as shown on your form including the all-caps formatting. The software is primarily looking for the key identifying information (Department of Treasury, Internal Revenue Service, Kansas City location) rather than exact formatting. But some programs are pickier than others, so if the normal format doesn't work, definitely try the exact match approach. You might also try calling the IRS directly or using one of those callback services others mentioned if you keep running into issues - they can confirm the exact format your specific tax software needs.

For the ZIP code, you can usually find the correct 9-digit one by looking up the IRS Kansas City office on the official IRS website or calling them directly. However, based on what I've seen in this thread, 64108-2203 seems to be the most commonly accepted one for Treasury Department 1099-INT forms. As for the capitalization, most tax software can handle either format, but I'd recommend entering it exactly as it appears on your form first - so "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps. If that gets rejected, then try the more standard format like "Department of the Treasury - Internal Revenue Service." The software is usually looking for an exact match to what's in their database, so starting with what's printed on your actual form gives you the best chance of success on the first try.

Good questions! For the ZIP code, you can usually find the specific extension by looking at the postmark on the envelope your 1099-INT came in, or by calling the IRS directly (though that's a pain with the hold times). In my experience, most Treasury Department 1099-INTs from Kansas City use 64108-2223, but if you're unsure, try the basic 64108 first - some tax software will accept that. For the capitalization, most tax software is flexible about that. You can enter "Dept of Treasury Internal Revenue Service" in normal caps and it should work fine. The software usually standardizes the formatting on the backend anyway. If you're still having trouble, you might want to check if your tax software has a "government payer" or "federal agency" option in a dropdown menu instead of typing it manually. Some programs have pre-loaded entries for common government entities that automatically use the correct formatting.

For the ZIP code, you can usually find the correct 9-digit version by looking up the specific IRS facility on their website or calling them directly. However, from my experience, most tax software will accept either 64108-2203 or 64108-2223 for the Kansas City processing center - they both route to the same facility, just different departments. Regarding the capitalization, I've found that most e-filing systems are pretty flexible with caps vs. normal text. You can usually enter it as "Dept of Treasury Internal Revenue Service" or "Department of the Treasury - Internal Revenue Service" and it should work fine. The software is mainly looking for the key identifying words to match up with their database. If you're still getting rejections, try starting with the format that worked for Harper: "Department of the Treasury - Internal Revenue Service" with the street address and just use 64108-2203 as the ZIP. That seems to be the most commonly accepted format across different tax software platforms.

Great questions! For the ZIP code, you can usually find the correct one by looking at the postmark on the envelope your 1099-INT came in, or check the IRS website's facility locator. From what I've seen, 64108-2223 is more commonly used for individual taxpayer correspondence, while 64108-2203 is typically for business forms, but when in doubt, either should work for e-filing purposes. As for the capitalization - definitely enter it exactly as it appears on your form, including the all caps format. Tax software is notoriously picky about matching the exact formatting from the original document. So if your form shows "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps, that's exactly how you should enter it. The e-filing system cross-references your entries against their database of known payers, so any deviation from the official format (even something as minor as capitalization) can trigger a rejection. Better to be safe and match it character for character!

Great questions! For the ZIP code, you can usually determine which one to use based on the type of form. From what I've seen, most 1099-INT forms from Treasury use 64108-2203, while some other Treasury documents use 64108-2223. If you're not sure, I'd start with 64108-2203 since that's more common for interest forms. Regarding the capitalization - most tax software will accept either format, but I've had better luck using normal capitalization like "Department of Treasury Internal Revenue Service" rather than all caps. The software seems to handle that better for validation purposes. If you're still having trouble after trying those formats, you might want to call your tax software's support line. They often have a database of common address formatting issues and can tell you exactly how to enter Treasury/IRS addresses for their system.

As for the capitalization, most tax software will accept it either way, but to be safe I'd enter it exactly as shown on your form: "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps. The IRS matching system is pretty strict about exact matches, especially this year. One more tip - if you're still having trouble, try breaking it into two lines in your tax software: Line 1: DEPT OF TREASURY Line 2: INTERNAL REVENUE SERVICE Some e-filing systems prefer the department and agency split up like that. Good luck getting it submitted!

Great questions! For the ZIP code, you can usually find the correct 9-digit version by looking up the IRS Kansas City processing center on the official IRS website or calling them directly. However, in my experience, most tax software will accept either 64108-2203 or 64108-2223 for the Pershing Road location - they both route to the same facility. Regarding the capitalization, I'd recommend entering it exactly as it appears on your form initially. So if your 1099-INT says "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps, try that first. If your software rejects it, then try the more standard format: "Department of the Treasury - Internal Revenue Service" or just "Internal Revenue Service" on the first line. Tax software can be really finicky about matching the exact format, but most will accept reasonable variations of the official name. The key is having the correct street address (333 W. Pershing Road) and a valid ZIP code. If you're still having trouble after trying both ZIP codes, the 5-digit version (64108) usually works as a fallback.

Great questions! For the ZIP code, you can usually find the specific 9-digit code by looking up the IRS Kansas City processing center online, but in my experience, either 64108-2203 or 64108-2223 should work - the tax software just needs the extended format to validate the address properly. Regarding the capitalization, most tax software is flexible about that. You can enter it as "Dept of Treasury Internal Revenue Service" in normal case, or keep it all caps like "DEPT OF TREASURY INTERNAL REVENUE SERVICE" - either should be fine. The important thing is getting the actual words and address correct. If you're still having trouble after trying both ZIP codes, you might want to try the format that worked for me: "Department of the Treasury - Internal Revenue Service" with the hyphen. Some software parsing is really picky about punctuation and abbreviations. Let us know if one of these combinations works for you!

Great questions! For the ZIP code, if your 1099-INT doesn't show one, you can usually find the correct one by looking at the specific type of interest or which Treasury division issued it. For most standard 1099-INTs from Treasury, 64108-2203 is the right one, but 64108-2223 is used for certain specialized accounts. If you're not sure, I'd actually recommend trying 64108-2203 first since that's the most common. If it gets rejected, then try 64108-2223. Most tax software will give you a specific error message if the ZIP doesn't match what they're expecting. As for the capitalization - you can usually use normal capitalization even if the form shows all caps. Most tax software converts everything anyway. So "Department of Treasury Internal Revenue Service" should work fine even though your form shows "DEPT OF TREASURY INTERNAL REVENUE SERVICE." The key is getting the words and address right, not the exact formatting.

For the ZIP code, you can usually find the correct 9-digit code by looking up the IRS Kansas City processing center on the USPS website or calling them directly. However, I've had success using 64108-2203 for most Treasury Department 1099-INT forms. If that gets rejected, try 64108-2223. Regarding the capitalization, most tax software is flexible about that. You can enter it as "Dept of Treasury Internal Revenue Service" or "Department of Treasury - Internal Revenue Service" - the software usually normalizes the formatting. The key is getting the core information and address correct. If you're still having trouble, try entering it exactly as it appears on your form first (all caps), and if that doesn't work, use normal sentence case. The IRS matching system is pretty forgiving on formatting variations as long as the essential details are right.

Great questions! For the ZIP code, try 64108-2203 first - that's the most commonly used extension for Treasury/IRS forms from the Kansas City processing center. If your e-filing software rejects it, then try 64108-2223. Most tax software will give you a specific error message if the ZIP is wrong, so you'll know pretty quickly. For the capitalization, you can use normal capitalization - the software usually standardizes that automatically. So "Dept of Treasury Internal Revenue Service" or "Department of Treasury Internal Revenue Service" should work fine. The key is getting the actual words and address right, not the caps. One more tip: if you're still having trouble, try entering it as two separate lines in the payer name field: Line 1: Department of Treasury Line 2: Internal Revenue Service Some software handles multi-line payer names better that way. Good luck with your filing!

Great questions! For the ZIP code, you can usually find the specific 9-digit code by looking at the envelope your 1099-INT came in if you still have it. If not, I'd suggest starting with 64108-2203 since that's the most common one for Treasury Department forms. If your e-filing gets rejected, then try 64108-2223. As for the capitalization, most tax software will accept either format. I'd recommend entering it exactly as it appears on your form first ("DEPT OF TREASURY INTERNAL REVENUE SERVICE"), and if that doesn't work, try the more standard format ("Department of the Treasury - Internal Revenue Service"). The software is mainly looking for the key identifying information to match their database, so small formatting differences usually don't matter as much as getting the core address and ZIP code right. Let us know if you're still having trouble after trying these!

Good question about the ZIP codes! The 9-digit extension usually depends on which specific division or function within the IRS issued your 1099-INT. Since your form doesn't show a ZIP code, I'd recommend starting with 64108-2203 as that's the most commonly used extension for the Kansas City processing center. Regarding the capitalization - most tax software is flexible with caps vs. normal text, but since you're having e-filing issues, I'd suggest entering it exactly as shown: "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps. Some systems are stricter about matching the exact format from the original document. If 64108-2203 doesn't work, try 64108-2223. And if you're still having trouble, you might want to check out that taxr.ai tool others mentioned - it seems like it's specifically designed to handle these formatting issues with government forms.

Good question about the ZIP codes! The different extensions usually correspond to different processing divisions. For most 1099-INT forms from the Treasury Department, 64108-2203 is the standard one to use. That's what worked for me when I had this same issue. As for the capitalization, most tax software will accept either format. I'd recommend entering it exactly as it appears on your form first (all caps), and if that gets rejected, try it with normal capitalization. The software is usually looking for the key words "Department," "Treasury," and "Internal Revenue Service" rather than the exact formatting. One tip that saved me a lot of headaches - if you're still getting rejections after trying both ZIP extensions, call your tax software's support line. They often have a database of common address formatting issues and can tell you exactly how to enter it for their specific system.

For the ZIP code, I'd recommend trying 64108-2203 first since that's what most people have had success with for 1099-INT forms from the Treasury Department. If that gets rejected, then try 64108-2223. The different ZIP+4 codes correspond to different divisions within the same facility. Regarding the capitalization - most tax software will accept either format, but I'd actually recommend entering it exactly as it appears on your form ("DEPT OF TREASURY INTERNAL REVENUE SERVICE") to avoid any potential matching issues. The IRS systems are designed to handle the all-caps format since that's how they print most official documents. If you're still having trouble after trying both ZIP codes, you might want to check if your tax software has a "government payer" or "federal agency" option that automatically formats these addresses correctly. Some programs have this feature specifically because of how common this issue is.

Great questions! For the ZIP code, you can usually find the specific 9-digit code by looking up the IRS Kansas City processing center online or calling them directly. From what I've seen, 64108-2203 is more commonly used for individual taxpayer correspondence, while 64108-2223 tends to be for business-related items, but don't quote me on that. Regarding the capitalization - most tax software will accept either format, but I'd recommend entering it exactly as it appears on your form to be safe. So if your 1099-INT says "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps, go with that. The software is looking for an exact match to what the IRS has on file. If you're still having trouble after trying both ZIP codes, you might want to try one of those tax document analysis tools that @Sunny Wang mentioned earlier. Sometimes it's easier to let technology figure out the exact formatting requirements than to keep guessing!

Good question about the ZIP code! The specific 9-digit extension usually depends on which division or processing unit within the Kansas City facility issued your 1099-INT. Since your form doesn't show a ZIP code, I'd recommend trying 64108-2203 first as that's the most commonly used extension for individual tax document processing. For the capitalization issue - most tax software can handle either format, but to be safe I'd enter it exactly as shown on your form: "DEPT OF TREASURY INTERNAL REVENUE SERVICE" in all caps. The e-filing system does matching based on exact text sometimes, so staying true to what's printed reduces the chance of rejection. If 64108-2203 doesn't work, then try 64108-2223. One of those should get you through! The software is just being overly picky about having a complete address format.
