Legal Answers
Q. What penalties will I receive for submitting taxes as a dual LLC if we were a sole member in 2020?
A: We are a sole member LLC? That sentence doesn't sound right. This sounds like a marital partnership. There's no additional tax or penalty for filing as a partnership vs a Sole-proprietership. Assuming that the partnership return was filed timely. The difference is that two people are picking up the income instead of one. If you have an LLC that you run solo and your preparer filed as a partnership with your spouse the difference will be that your spouse is getting credit for 1/2 of the LLC income for last year. It may effect other credits, but I'd need more information. I would discuss this with the agency and see why this happened, should it be corrected, and what are they going to do to fix it. The procedures for amending a partnership return are much more complicated than a personal return. You may have to find someone new to amend. No you won't be automatically audited. If the return was filed timely there won't be any penalties. If it was filed late the penalty can be waived under certain circumstances. Really would need more information than you should post online to give you a better answer. Good luck
Q. How to move a Nevada LLC to Colorado? I want to preserve the company history and EIN but I don't want in Nevada anymore.
A: Yes. You can create a new CO LLC and have that LLC acquire the NV LLC. Then merge the two with the CO LLC surviving. Or File a foreign registration in CO for the NV LLC. Then convert the CO foreign LLC to a domestic LLC. Dissolve the NV LLC. That moves the LLC from NV to CO without the merger and no interruption of entity status for tax elections, EIN, contracts, and other fun things.
Q. Can lawyers donate their older versions of Colorado Revised Statutes and Court rules and civil procedures to public?
A: There's no prohibitions on what lawyers do with old books. I haven't had a physical copy of a legal book in four or five years. Most of the larger firms put out a notice that the old books are available if anyone is interested in picking them up.
