What Documents Do I Need to File My LLC Taxes?

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.

Business Records and Documents You Will Need

Depending on your type of business, you may have different records and use various formats. For example, an Internet retailer won’t have printed cash register tapes as a brick-and-mortar retailer might. The basic categories of documents required to complete a return for an LLC are the same for all businesses, however. They include the company’s income, expenses, assets and payroll, among other things. Here are details on each:

Income Records

The most basic supporting documents are those showing gross business revenues for the year. These provide justification for the income figures reported. Key records in this category may include:

Business bank account deposits tracing payments received
Cash register tape receipts documenting each sale
Issued customer receipts
Invoices sent to clients
1099-NEC forms if the business was paid more than $600 as a contractor

Expense Records

An LLC also needs evidence to support the various operating expenses deducted to lower its taxable income. Supporting documents for expenses can include:

Canceled checks showing vendor payments
Invoices for products and services purchased
Credit card statements tracing individual charges
Bank and credit card statements to prove payment

Asset and Depreciation Records

LLCs that own assets also must maintain purchase and sales records related to those assets. This documentation should note:

Date and method the asset was acquired
The purchase price and any sales fees
Cost of improvements made over time
Deductions taken for prior depreciation expense
Any casualty losses recorded
How the asset was used in the business
Date the asset was sold or disposed of
The sale price when the asset was sold along with any related fees

Payroll Records

For LLCs with employees beyond just the owners (unless the LLC is taxed as a corporation, in which case would include owner salary), payroll-related records also come into play for tax purposes. Documents to retain here include:

Annual W-2s issued to each worker
Quarterly and annual payroll tax returns filed
State payroll tax and unemployment tax returns
Complete pay records for each employee, such as time sheets

Tips for Filing Your LLC Taxes

Filing taxes for your LLC can feel complicated, but keeping your paperwork organized and following a few key strategies can make the process smoother. Whether you operate as a single-member or multi-member LLC, understanding what to prepare and how to report it can help you avoid mistakes, reduce your tax liability, and stay compliant with IRS requirements. Here are some practical tips to guide you through filing your LLC taxes effectively.

Keep Detailed Financial Records: Accurate bookkeeping is essential for filing LLC taxes. Maintain organized records of income, expenses, receipts, and bank statements throughout the year. Good record keeping not only makes tax filing easier but also ensures you have documentation ready in case of an IRS audit or if you need to claim business deductions.
Understand Your LLC’s Tax Classification: The IRS doesn’t recognize LLCs as a separate tax entity, which means your filing process depends on your chosen classification, sole proprietorship, partnership, S corporation or C corporation. Knowing how your LLC is taxed determines which forms you file and how profits and losses are reported. Review your classification annually to ensure it still fits your business goals and tax situation.
Track and Deduct Business Expenses: Deductible expenses can significantly reduce your taxable income. Common deductions for LLCs include rent, utilities, business insurance, professional fees and vehicle costs. Be sure to only claim legitimate business-related expenses and keep clear records to support every deduction you take.
Pay Estimated Taxes on Time: If your LLC earns income that isn’t subject to withholding, you may need to pay quarterly estimated taxes. Missing these payments can lead to penalties and interest. Mark your calendar for due dates (typically in April, June, September and January) to stay ahead of your obligations and avoid surprises at tax time.

By keeping your documents organized, understanding your tax structure and planning ahead for payments and deductions, you can simplify the process of filing your LLC taxes. If your situation is complex or you’re unsure about certain forms, consulting a certified tax professional can help ensure accuracy and maximize your savings.
