For us to process your tax return I will need the following information
Corporations–both C and S–have a filing deadline of March 15 (the next Monday if the 15th falls on a weekend). Partnerships have the same deadline as individuals (usually April 15).
There are no federal tax filing requirement specifically for LLC’s. The basic rule is that if the LLC has more than one member (owner), it must file a partnership return. If there is only one member, the LLC is considered a disregarded entity and its income and expenses are reported on the personal return.
