Here’s the trick: use the official “Where to File” page on IRS.gov. I know, I know—government websites look like they were designed by a committee of confused squirrels. But stick with me.
You’ll plug in your state, the type of form (say, a 1040), and whether you’re including a payment. The site spits out a specific street address. That is your golden ticket.
Side note: if you’re mailing a check, write your Social Security number and the tax year on the memo line. Yes, it feels weird. Do it anyway. The IRS loves a paper trail.
What About Estimated Tax Payments?
If you’re self-employed or gigging it, you probably make quarterly payments. Good for you, real go-getter. But where do those go? Not the same address as your annual return—sorry.
Should You E-File or File Taxes by Mail?
Estimated tax payments (Form 1040-ES) have their own set of mailing addresses. Again, the IRS website has a specific lookup for that. Pro tip: electronic payment via IRS Direct Pay is much faster and more idiot-proof. You can schedule it from your couch in your pajamas.
Ironic confession: I still mail a check sometimes because I like the control. But every time I lick that envelope, I whisper a little prayer to the postal gods.
