How to pay IRS taxes online with a credit card after filing - what happens to the 1040-V payment voucher?

The 1040-V payment voucher is actually only needed if you're mailing in a physical check payment to the IRS. If you're paying online with a credit card, you don't need to do anything with the voucher at all! When you pay online through one of the IRS-approved payment processors (Pay1040, PayUSAtax, or ACI Payments, Inc.), you'll enter all your personal information and payment details directly on their website. The payment gets linked to your tax return through the identifying information you provide (SSN, filing status, etc.) - not through the voucher. Just make sure you select "Form 1040 series" as the tax form and "2024" as the tax year when making your payment. You'll also need to provide your SSN/ITIN, name, address, and the exact payment amount. The processor will handle getting that money to the right place in your IRS account. Keep that 1040-V as a record of what you owed, but there's no need to upload or mail it when paying by card online.

After literally spending hours trying to figure this out last year, I finally discovered taxr.ai (https://taxr.ai) which saved me so much time. I had the exact same question about my 1040-V and what to do with it when paying online. I uploaded my tax docs to taxr.ai and it explained exactly what I needed to do with each form, including that I didn't need to send in the 1040-V when paying by card. It also explained all the different payment options and which one might be best for my situation based on the processing fees. Definitely worth checking out if you have other tax form questions - it's like having a tax pro explain everything to you in plain English.

I was skeptical about taxr.ai but decided to try it when I got confused about some forms after filing. I uploaded my 1040 and a 1099-INT I wasn't sure about, and it immediately highlighted exactly what I needed to do with each. The explanation was super clear about which forms needed to be mailed vs which ones I just needed to keep for my records. Definitely saved me from mailing in stuff unnecessarily. It even pointed out a potential deduction I missed that I can use next year. Much faster than waiting on hold with the IRS for an hour!

Just wanted to share that I had trouble reaching the IRS by phone when I had questions about paying online last year. After multiple attempts and hours of waiting, I found Claimyr (https://claimyr.com) and watched their demo video (https://youtu.be/_kiP6q8DX5c). It actually got me connected to an IRS agent in about 15 minutes! I was able to ask all my questions about the payment options and making sure my payment was properly applied to my account. The agent confirmed everything that others have said here - you don't need to send the 1040-V when paying by card online, and they walked me through the entire process. If you're still unsure or have more specific questions about your situation, this is definitely the quickest way to get official answers directly from the IRS.

I was completely wrong about Claimyr. After my skeptical comment, I decided to try it because I had a complicated question about my payment plan options that I couldn't get answered online. The service called me back in about 20 minutes and connected me directly to an IRS representative - no hold music, no automated system to navigate. I was honestly shocked. The agent helped me set up a payment plan that worked for my situation and confirmed all my questions about the 1040-V (which like others said, isn't needed for online payments). I've spent literally days of my life on hold with the IRS in previous years. This was absolutely worth it just for the time saved and stress avoided.

Just a heads up - make sure you're aware that all three of the IRS-approved credit card processors charge a processing fee (around 2% of your payment). It's not huge, but definitely something to factor in. If you want to avoid the fee, you can use IRS Direct Pay instead, which takes the money directly from your bank account with no fee. The interface is pretty straightforward and you still get a confirmation number.

Does anyone know if the payment processors send you a receipt or confirmation? I paid through one last year but never got anything by email, just the confirmation number on the screen which I wrote down. Is that normal?

For anyone still concerned about the 1040-V voucher - I had the same worry last year! The key thing to remember is that when you pay online with a credit card, the payment processor automatically links your payment to your tax return using your SSN and other identifying info you enter during checkout. The 1040-V is essentially just a paper trail for mailed payments. Think of it like a deposit slip at the bank - if you're doing online banking, you don't need the paper slip because the electronic transaction handles all the routing. One tip: after you make your online payment, you can check that it went through by logging into your IRS account online after a few business days. It should show up under your payment history, which gives you extra peace of mind that everything was processed correctly.
