According to the information on their website, IncFile can normally obtain a Tax ID within a single day. If you’ve already formed with them using their Silver plan that doesn’t include this feature, you can still purchase this service separately—all you need to do is use an online form for EIN acquisition and pay the service fee. Find out more about the fees on IncFile’s pricing page. Note, however, that you can do so on your own directly through the IRS online application form in which case you won’t need to pay extra.
