  1. Wow, what a find your site and videos are Matt! Thank you so much and well done

  2. Hi, thank you for all the information here,
    I was wondering, I registered for the EIN before the LLC, It says that its required to inculde one of the LLC abbreviation, so that what I did for the LLC registeration, However I didnt do the same for the EIN, should I change the EIN ?
    thank you

    • Hi Sanaa, you’re very welcome :) So you obtained an EIN for your LLC (“Big Ski Lodge LLC”, as an example) before your LLC was approved. You told the IRS you have an LLC in the “What type of legal structure is applying for an EIN?” section of the EIN application, however, when it came to entering your LLC name, you entered “Big Ski Lodge” and forget to add “LLC”.

      In that case, yes, you want the full legal name or your LLC appearing on your EIN Confirmation Letter. While you can change the business name associated with the EIN, you have to mail or fax a letter to the IRS. And because of all their delays right now, you won’t get a response back for at least 2 months.

      Here’s an easier solution: Apply for a new EIN for your LLC using “Big Ski Lodge LLC”. And for the original EIN, you can file an EIN Cancellation Letter with the IRS. You can apply for the new EIN right away. You don’t have to wait for the first EIN’s cancellation to be processed. Hope that helps!

  3. Hi I was wondering if I needed to file a DBA with my LLC if they are very similar? Like for example lets say I filed my LLC as Southwest Bakery LLC, would I need a DBA if I refer to my business as Southwest Bakery with No “LLC” at the end?

    • Hi Minh, yes, you do. Anytime you want the LLC to represent itself without using its true and legal name, you will need to file a DBA. Hope that helps.
