Federal Tax forms

We're not receiving as many tax forms from the feds as we used to, so many people are doing their taxes online or electronically. We still do have forms, of course, and here's a link to the IRS site (title of this article). Mass.gov also has links to Commonwealth of Massachusetts tax forms.
Let us know if you can't find what you need. We're not tax experts, so can't give advice, but we can find forms!
