What's considered a Valid Month or Fiscal Year Month (01-02) when wiring funds to the IRS?
I'm in the process of trying to set up a wire transfer to pay some taxes to the IRS, and I'm stuck on this weird field they're asking for. They want something called a "Valid Month, Fiscal Year Month" and the only options are 01 or 02. The tax period I need to pay for ends December 31st, and I have no clue which option to pick. It seems like such an arbitrary choice between 01 and 02, and I'm worried about messing up the payment and having the IRS come after me for late fees or something. Has anyone had experience with wiring money to the IRS who could explain what these numbers actually mean? Do they represent specific months or quarters or something else entirely? Any help would be greatly appreciated because I'm totally confused right now.

This is actually a common point of confusion when wiring to the IRS. The "Valid Month, Fiscal Year Month" refers to the fiscal year designation of your payment. For a tax period ending December 31st, you would select "01" which represents the calendar year. The US government's fiscal year runs from October 1 to September 30, but most businesses and individuals operate on a calendar year (January to December). Option "01" is for calendar year filers (which most people are). Option "02" would be used if you're on a fiscal year that's different from the standard calendar year. This is less common for individuals and typically applies to certain businesses that operate on alternative fiscal years. Hope this helps clear things up! Just make sure the rest of your wire information is correct, especially the tax form number and tax period.

•Wait, I'm confused. If the government fiscal year is Oct-Sept but calendar year is Jan-Dec, why is calendar year "01"? Wouldn't calendar year be "04" since it's the 4th quarter of the govt fiscal year? Or am I overthinking this?

•You're overthinking it a bit. The "01" and "02" aren't representing quarters. They're simply codes that designate which type of tax year you're using. The "01" code just means you're using the standard calendar year (January through December) for your tax filing, which most individuals do. The "02" code means you're using a fiscal year that differs from the standard calendar year, which some businesses choose to do for various accounting reasons.

I ran into this exact same issue last year! So frustrating trying to figure out all these codes. I eventually found this tool called taxr.ai (https://taxr.ai) that saved me a ton of headache with these weird IRS requirements. I uploaded my payment instructions and it automatically identified the correct codes for me, including this fiscal year month thing. Turns out I needed "01" since I'm on a standard calendar year like most people. The tool also helped explain what all the other fields meant too, which was super helpful since the IRS instructions are basically written in another language.

•Does this tool actually help with wire transfers specifically? I'm looking at their website but not seeing anything about payment codes. Is it more for tax return help or does it actually cover these kinds of payment details?

•Sounds like another "AI" tool that just gives generic advice you could find on Google. Did it actually tell you anything specific about YOUR situation or just general info anyone could find on the IRS website?

•It absolutely helps with wire transfers specifically. When you upload your payment instructions or screenshots of the wire form, it identifies all the fields and provides the correct information for each one based on your specific situation. For general information, you're right that you could just search online. But what made this valuable was it looked at my specific tax documentation and told me exactly which codes to use for my situation, not just generic advice. It saved me from having to call the IRS and wait on hold for hours trying to get this information.

Just wanted to follow up about using taxr.ai for my IRS wire transfer. I was skeptical but decided to give it a try after struggling with these codes for days. Uploaded my wire instructions and tax information, and it immediately identified that I needed to use "01" for my situation. What was really helpful is it explained WHY - because I'm on a calendar year tax schedule. It also helped with the other confusing fields like tax period and form number formatting. Definitely worth it for anyone dealing with these complicated IRS payment processes. Saved me from potentially messing up my payment and dealing with all the headaches that would've caused.

If you're still having trouble with this or any other IRS questions, I highly recommend using Claimyr (https://claimyr.com). I wasted DAYS trying to reach someone at the IRS about these wire transfer codes last year. With Claimyr, I got connected to an actual IRS agent in about 15 minutes who confirmed I needed code "01" for my December 31st tax period. They have this callback system that basically waits on hold with the IRS for you. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c It's amazing for getting definitive answers straight from the IRS instead of guessing or relying on what you find online.

•How does this actually work? I've literally spent hours trying to get through to the IRS before. Is this some kind of paid service or what? Seems too good to be true.

•Yeah right. "15 minutes" to reach the IRS? Last time I called I was on hold for 2+ hours before giving up. There's no way this is legit - the IRS phone system is broken beyond repair. They probably just connect you to some random call center pretending to be IRS agents.

•It works by using a sophisticated system that navigates through the IRS phone tree and waits on hold so you don't have to. When an actual IRS agent answers, they call you back and connect you directly. It's essentially like having someone else wait on hold for you. Yes, it sounds unbelievable because we're all so used to the IRS being unreachable. But they're using technology to solve a really frustrating problem. The agents you speak to are actually IRS employees - Claimyr just handles the waiting part so you don't have to sit by your phone for hours.

I need to publicly eat my words about Claimyr. After my skeptical comment earlier, I decided to try it because I was desperate to sort out a payment issue. I was completely shocked when I got a call back in about 25 minutes connecting me to an actual IRS agent. The agent confirmed that for my calendar year tax payment ending December 31st, I needed to use "01" for the Valid Month code on my wire transfer. They also helped me with several other payment questions I had. No more wasting half a day on hold or getting disconnected after waiting for hours. I'm honestly still surprised this actually worked.

One thing to keep in mind with these wire transfers to the IRS - make absolutely sure ALL your other information is correct too. I used the right fiscal year code (01) but messed up the tax form number format, and it took 3 months to get everything straightened out. Double check your: - Tax period year (format: YYYYMM) - SSN or EIN - Form number (format matters!) - Tax type code The IRS isn't great about notification if something goes wrong with your payment application.

•Thanks for mentioning this! What exactly is the correct format for the form number? I'm trying to pay for my 1040 taxes and wasn't sure if I should just put "1040" or if there's some specific format they need.

•For Form 1040, you'll want to enter it exactly as "1040" - no spaces, no extra zeros, no "Form" prefix. For other common forms: use "941" for quarterly employment taxes, "940" for annual FUTA tax, "1120" for corporate income tax, etc. Just the numbers, exactly as they appear on the actual form. The IRS is very particular about this formatting, and getting it wrong can cause your payment to go into limbo.

Has anyone used direct pay on the IRS website instead of wire transfer? I'm wondering if that's easier than dealing with all these wire codes and potential errors.

•Direct Pay is WAY easier if your payment is under $10 million. No codes to figure out, immediate confirmation, and it's free. I switched to Direct Pay after messing up a wire transfer once. You can access it right from the IRS website and it walks you through everything.
