Me and 3 others just established an LLC in arizona how do we file taxes

[tagteam]

The LLC, as a multi-member LLC (presumably with no election to be treated as an S or C corporation), will be required to filed a Form 1065 and associated K-1 forms with the IRS and most likely a Form 165 Partnership Income Tax Return with AZ.

TurboTax Business is capable of preparing a Form 1065 for a multi-member LLC but it is not available online or for a Mac; the program must be installed and run in a Windows environment.

See https://turbotax.intuit.com/small-business-taxes/

Note that you should absolutely retain legal counsel and professional tax guidance, for this, your first year in business, as a member of a multi-member LLC.

The IRS will automatically consider your business a Partnership unless you make the election with them to be taxed as a Corporation.  

A Partnership files Form 1065 and a Corporation files Form 1120 (or an 1120-S, if you make the Sub-Chapter S election as well.) These can be complex decisions and it might benefit you to discuss them with a professional.

If you choose to be a Partnership or 1120-S Corporation, you must file your business returns first, before you file your personal returns, as you will create Form K-1, which is then included in your personal return.

The TurboTax Business software is separate from your personal tax filing software and may be found at TurboTax Small Business Taxes.

The multi-member LLC/Partnership will file it's own physically separate IRS Form 1065 Partnership return. The partnership will then issue each owner a K-1 which each owner will need in order to complete their own individual personal 1040 tax return.

The partnership return is due March 15, 2020 and the late filing penalty is $200 per month, per partner. So don't be late. Otherwise, if you file the partnership return one day late, you're looking at a $600 late filing penalty.

To complete and file the 1065 partnership return you must use a physically separate program called TurboTax Business. You can get it at https://turbotax.intuit.com/small-business-taxes/ and let the partnership pay for it as a business expense.
