FAQ

Common questions

View all
Does a filing extension also give me more time to pay?

Generally, no. An extension gives more time to submit the applicable return, while tax usually remains due by the original payment deadline. Prepare an estimate, account for payments already made and check federal and state requirements separately.

Does an LLC with no profit still need a tax review?

Yes. No profit does not resolve every filing obligation. Review the LLC’s tax classification, ownership, transactions, elections and relevant state requirements. Bring the formation documents, EIN confirmation, bank activity and any foreign-ownership information.

IRS · LLC

Do I need to review income if I did not receive a 1099?

Yes. A missing information form does not by itself remove the need to report taxable income. Reconcile payments with your records, including side work and platform activity, and identify missing or incorrect forms before preparing the return.
