So in shot- there is nothing to consider- it's a requirement and if you haven't been doing it you should find a tax professional to correct it via amendment or 3115. 

The other side of the duplex has some minor issues of conduct, but I can handle those with a few property amendments (like adding a fenced in place to smoke outside and more garbage cans for the whole building) and a brief conversation.

“Due process” originated in 1215 with the English Magna Carta, an important provision of which was that no freeman would be deprived of certain rights except “by the judgment of his peers and by the law of the land.” https://www.cincinnati.com/story/news/2020/06/04/cincinnati-evictions-judges-reopen-eviction-court-after-landlord-sues/3144939001/https://www.law.cornell.edu/constitution-conan/amendment-14/section-1/due-process-of-law

Hi,I opened an LLC several months ago, but misspelled the name when i opened it.When i wanted to start doing business with this LLC, i realized that the LLC was registered with the wrong name in the city, state and IRS records.After filing a certificate of amendment with my state, the name of the LLC was adjusted and the city/state records have been updated with the new and correct name.I would like to know where i can find out if the IRS records were updated aswell following the certificate of amendment, and do i need to file any specific forms with the IRS in order to change the name in their records?
