What Documents Do I Need to File My LLC Taxes?

News Room

If you are the owner of an LLC and want to file the correct tax return for your business, the job starts with gathering the right documents. You’ll need records to validate all your business’s income, deductions, expenses and other figures reported across various forms. The tax forms you’ll use vary depending on whether you have a single or multi-member LLC or are filing as a corporation. However, no matter what forms you’re filing out, keeping and having access to thorough records is key to smooth tax filing. It doesn’t matter to the IRS whether these records are in electronic or paper formats, but they do need to be complete, clear and up to date. To make sure you’re doing your LLC tax return correctly, talk to a financial advisor who specializes in small business taxes.

LLC Tax Filing Basics

A limited liability company (LLC) is a business structure that combines some aspects of sole proprietorships or partnerships with corporations. Similar a corporation, an LLC protects its owners from personal liability for business debts and legal issues. And like a sole proprietorship or partnership, owners of most LLCs report LLC profits and losses on their personal tax returns rather than the business paying taxes itself.

LLCs register with the states, and the IRS doesn’t recognize LLCs as a taxable business entity. There is no federal LLC return, although states may have forms for LLC taxes. Instead, at the federal level each LLC’s tax status is assigned by default depending on the business ownership structure. This determines how the LLC files and which forms are used. Here are three options:

  • Single-member LLCs report business income and losses on Schedule C, which attaches to the owner’s Form 1040 personal tax return.
  • Multi-member LLCs file an informational Form 1065 showing total income and expenses plus Schedule K-1s documenting each member’s share. The members report their K-1 amounts on Schedule E with their Form 1040.
  • An LLC taxed as a C corporation pays taxes on its income before distributing profits to shareholders, and and LLC taxed as an S corporation passes through its income to its shareholders’ personal returns. If you elect to have your LLC taxed as a corporation, you’ll file Form 1120 if it is a C corporation or Form 1120-S if it is an S corporation.

No matter its tax status or the forms used, an LLC must maintain documents supporting all numbers entered on returns. The IRS may request proof of any figures during an audit or review.
