What documents do I need to file my LLC taxes?

If you're running an LLC and gearing up for tax season, you're probably asking yourself the big question: what documents do I need to file my LLC taxes. It’s a common concern and understandably so. Between figuring out how your LLC is taxed and gathering all the paperwork, it can feel difficult but the truth is, it doesn’t have to be difficult. Filing your LLC taxes becomes much more manageable when you understand what’s required and how to prepare.

What Documents Do I Need to File My LLC Taxes as a Single-Member LLC?

If you're the only owner of your LLC, the IRS treats your business as a disregarded entity, meaning your business income and expenses are reported directly on your personal tax return.

Forms You'll Need to File

You’ll use Schedule C to report your LLC’s income and expenses. This form gets attached to your Form 1040, which is your individual federal tax return. In addition to Schedule C, you’ll also need Schedule SE, which is used to calculate your self-employment taxes. These include Social Security and Medicare taxes and since you’re self-employed, you’ll be responsible for the full amount instead of splitting it with an employer.

Records and Reports to Prepare

To accurately complete your forms, you’ll need a profit and loss report that summarizes your income and business expenses for the year. It’s also important to gather receipts, bills, and purchase records for anything you bought for your business especially if it was equipment or tools that may be depreciated over time.

Additional Documents for Deductions

If you’re working from home and plan to take the home office deduction, keep a worksheet or spreadsheet that shows the percentage of your home used for business, your rent or mortgage amount, utility bills, and other related costs. And if you use your vehicle for business purposes, make sure to track your mileage carefully with a mileage log.

What Documents Do I Need to File My LLC Taxes as a Multi-Member LLC?

If your LLC has more than one member, then the IRS treats it as a partnership by default. This changes the way your taxes are filed and what documents you need to have ready.

Filing Form 1065 for the Business

The main tax form for multi-member LLCs is Form 1065. This is the partnership return that reports the business’s income, expenses, profits, and losses. It covers the activity of the entire LLC for the year and must be completed before you move on to individual member filings.

Issuing Schedule K-1s to Each Member

Once Form 1065 is prepared, you’ll need to generate a Schedule K-1 for each member of the LLC. This form shows that member’s share of the company’s income, deductions, and credits. Each K-1 is then used by the members when filing their own personal tax returns.

Documents You’ll Need to Prepare

To complete everything properly, you’ll need several key documents. Start with a detailed income and expense report for the year, which should show all the money the business brought in and spent. You’ll also need records of capital contributions made by each member, which are any amounts they personally invested in the company. On top of that, you should document any distributions made to members during the year basically, any profits paid out.

If your LLC has an operating agreement that explains how profits are split among members, make sure you have that handy too. And if your LLC has employees, be sure to include payroll reports and tax filings for wages paid.

Filing at the Individual Level

After all this, each member will take their Schedule K-1 and report that income or loss on their personal income tax return (Form 1040). So when asking what documents do I need to file my LLC taxes as a partnership, remember you’re filing for the business as a whole, and then helping each member file their share individually.

Understand How Your LLC Is Taxed

Before getting into the paperwork, it’s important to understand how the IRS views your LLC. The way your LLC is taxed shapes what forms you’ll need and what documents to collect. By default, if you’re the only owner, your LLC is treated as a disregarded entity, meaning it’s taxed like a sole proprietorship. If there are two or more owners, it’s treated as a partnership. You also have the option to elect to be taxed as an S Corporation or a C Corporation, depending on your goals and business structure.

Each of these tax classifications has its own set of documents and forms. So, knowing how your LLC is taxed is the first step in figuring out what documents do I need to file my LLC taxes.

Essential Documents for All LLCs

No matter how your LLC is taxed, there are a few must-have documents that every business should have ready before tax season.

Employer Identification Number (EIN)

One of the first things you’ll need is your Employer Identification Number (EIN). This is basically your LLC’s identity when dealing with the IRS. Think of it like your business’s Social Security number. It’s required when you file your taxes, hire employees, or open a business bank account.

Business Income Records

Next, you'll need clear records of all business income for the year. That means you should be tracking everything your business earned—from invoices, online sales, and service payments to transfers made through platforms like PayPal, Stripe, or your business bank account. These income records give you and your tax preparer a clear view of your financial year.

Expense Documentation

Expenses are just as important. Every deduction you plan to claim needs proper backup. This includes receipts, vendor invoices, bills, mileage logs, and utility statements if you’re claiming a home office. Anything that proves you spent money on your business should be saved.

Bank and Credit Card Statements

Don’t forget your monthly bank and credit card statements. These help verify your income and expense claims and are often used for cross-checking during reconciliation. Even small transactions can make a difference during tax filing.

Putting It All Together

So, if you're asking what documents do I need to file my LLC taxes, this basic set of income records, expense documentation, identification details, and financial statements is the place to start. Having these organized will make everything else that follows much smoother.

How to File Taxes as S Corporation LLC

Many LLC owners choose to be taxed as an S Corporation because it can reduce the amount they owe in self-employment taxes. This setup can offer savings, but it also comes with more forms to file and additional records to maintain.

Forms You’ll Need to File as an S Corp

If your LLC is taxed as an S Corporation, you’ll be required to file Form 1120-S, which is the main tax return for S Corps. In addition, each owner or shareholder must receive a Schedule K-1 that outlines their share of the company’s income, deductions, and other financial details.

Since S Corp owners are expected to pay themselves a reasonable salary, you’ll also need to file payroll-related forms like Form 941 (quarterly federal tax return) and Form 940 (annual federal unemployment tax return). Your salary must be reported through a W-2, just like any other employee.

Supporting Records You Should Keep

Throughout the year, it’s important to keep organized records of payroll transactions, including how much you pay yourself and any other employees. You should also track health insurance payments, especially if the company provides coverage, as well as any retirement contributions made on behalf of employees or owners. In addition, document any profit distributions taken outside of your regular salary.

So when someone asks what documents do I need to file my LLC taxes under S Corporation status, the answer is a mix of official tax forms and detailed financial records that prove your salary, deductions, and distributions are all handled properly.

How to File Taxes as C Corporation LLC

If your LLC has chosen to be taxed as a C Corporation, then things are treated differently. The company files its own tax return using Form 1120 and pays corporate taxes on its profits. If you’ve taken a salary from the business, that’s filed through payroll. If you’ve received dividends, those go on your personal tax return. To prepare the corporate return, you’ll need full financial statements, a list of assets, payroll records, dividend payout logs, and documentation for every deductible expense. 

C Corps are subject to double taxation once at the corporate level and again at the shareholder level so it’s crucial to keep records clean. The question what documents do I need to file my LLC taxes becomes even more important with C Corps, because mistakes or missing paperwork can have bigger financial consequences.

Important Tax Documents

LLC taxes aren’t just about federal forms there are some state and local documents you might need too. These often get overlooked but are just as important to stay compliant.

You may need:

• Form 1099-NEC – If you paid any contractor over $600.

• Sales Tax Filings – Monthly or quarterly, if your state requires sales tax collection.

• Business License Renewal – Proof that your LLC license is current.

• Annual Reports – Required in many states to maintain LLC status.

• Franchise Tax Filings – Some states charge a flat annual LLC fee.

So when thinking what documents do I need to file my LLC taxes, don’t forget the state and local side missing these can lead to penalties.

Should You Use an Accountant or Tax Software?

Whether you need an accountant or can manage with tax software really depends on how complex your LLC is. If you’re a solo owner with simple income and expenses, tools like TurboTax or H&R Block might be enough. But if your LLC is taxed as an S Corp or C Corp, has employees, or involves more complicated filings, hiring a CPA can save you time, stress, and possibly money.
