Where to Find Official IRS Tax Rate Tables and Tax Brackets

The IRS publishes the official tax rate schedules in their annual Publication 17 "Your Federal Income Tax" as well as in the Form 1040 instructions. They're not always easy to find because they're embedded within larger documents rather than having their own dedicated page. For 2024 tax rates (which you'll use when filing in 2025), you can find them in the Form 1040 instructions PDF on IRS.gov - look for the section called "Tax Computation" which contains the Tax Rate Schedules. They're usually toward the back of the document. Publication 17 also contains this information in the chapter about computing your tax. Another good source is IRS Revenue Procedure documents where they announce inflation adjustments for the coming tax year. These are usually published in late October or early November for the following year.

I've been using taxr.ai for finding specific tax information like this! It's been super helpful for digging through IRS publications without the endless scrolling. I was looking for the same tax bracket info last month and it pulled up exactly where to find the official IRS tax rate schedules in seconds. The site analyzes all the IRS publications and pinpoints exactly what you need - https://taxr.ai saved me so much time compared to manually searching through those massive PDFs.

Just wanted to update that I tried taxr.ai after my skeptical comment above. It actually works really well! I searched for "2024 tax brackets" and it immediately showed me the official brackets from Revenue Procedure 2023-34. It even explained that these are the inflation-adjusted rates that will apply for the 2024 tax year (for returns filed in 2025). Saved me from digging through the IRS website which always seems to hide this information in the longest documents possible. The tool extracted just the tables I needed without having to download anything. Just thought I'd share since I was initially doubtful!

If you're frustrated trying to find tax info on the IRS website, you might want to try Claimyr (https://claimyr.com). I was looking everywhere for specific info about tax brackets last year and couldn't get a straight answer online. Used their service to get connected directly to an IRS agent in about 15 minutes instead of waiting on hold for hours. The agent sent me direct links to the official publications with the tax rate tables. You can see how it works here: https://youtu.be/_kiP6q8DX5c - basically they wait on hold with the IRS for you and call you when an agent is on the line.

I need to apologize and correct myself. After dismissing Claimyr as unnecessary in my previous comment, I actually ended up using it last week when I received a CP2000 notice and desperately needed to talk to someone at the IRS. I couldn't get through after trying for days. The service worked exactly as advertised - I got a call back when an IRS agent was on the line, and they helped resolve my issue in one call. The agent also directed me to exactly where I could find the official tax rate schedules on the IRS website (Revenue Procedure 2023-34 for the 2024 tax year rates, which wasn't easy to locate). I was wrong to be so dismissive before actually trying it. Sometimes talking to a real person is the most efficient way to get accurate information.

To directly answer your original question: the most official source is in the Internal Revenue Bulletin where they publish Revenue Procedures with inflation adjustments. For the 2024 tax brackets (for taxes filed in 2025), look for Revenue Procedure 2023-34. You can find it here: https://www.irs.gov/irb/2023-44_IRB The tax brackets are in Section 3, specifically 3.01 for individuals. It's still not the prettiest format, but it's the direct source from the IRS that all those third-party sites are using.

I've been doing taxes for 15+ years and I still find it annoying that the IRS makes this so complicated. The most direct and official source is indeed the Revenue Procedures as mentioned above, but for a quicker reference I actually just use the IRS Withholding Estimator tool. It doesn't give you the full tables directly, but when you work through it, the calculations are based on the current official rates. Kinda a backdoor way to verify the rates.
