LLC tax documents and write-offs: what to gather for each way an LLC is taxed
By Arthur Teboul, DokuTrak · Published
In brief
Tax write offs for an LLC are the same business costs any company deducts. The papers you gather depend on how the LLC is taxed: on Schedule C as a disregarded entity, on Form 1065 as a partnership, or on Form 1120-S with an S election.
The checklist: LLC records by tax status: one file per return
Tick the LLC’s tax status first: single-member, multi-member or S election. Then work through the shared groups and the group for that status, and mark the rest "n/a".

First question: how is the LLC taxed?
An LLC is a creature of state law, and the IRS does not tax it as an LLC. By default, an LLC with two or more members is a partnership, and an LLC with one member is disregarded (IRS Publication 3402). A disregarded entity is a business the IRS ignores for income tax, so its income and costs land on the owner’s own return (IRS Publication 3402). It can elect corporate status on Form 8832, or S corporation status on Form 2553 (IRS Publication 3402).
So the first document to find is the one that fixes the status. That is the EIN confirmation letter, plus any Form 8832 or the IRS letter accepting a Form 2553. Without it, a preparer can pick the wrong return. Once an LLC changes its classification by election, it generally cannot change again for 60 months (IRS Publication 3402), so the date of any past election matters too.
Membership changes move the status without any election. For example, when a two-member LLC taxed as a partnership drops to one owner, it becomes a disregarded entity (IRS Publication 3402). Ask for the dates of any member joining or leaving, and the papers behind each sale of an interest.
| How the LLC is taxed | Return it files | What the owner gets |
|---|---|---|
| One member, no election | None of its own: Schedule C, E or F on the owner’s Form 1040 (IRS Publication 3402) | Nothing separate; the owner reports it all |
| Two or more members, no election | Form 1065, due by the 15th day of the third month after year-end (Form 1065 instructions (2025)) | A Schedule K-1 for each member (Form 1065 instructions (2025)) |
| Elected S corporation (Form 2553) | Form 1120-S (IRS Publication 3402) | A Schedule K-1, plus a W-2 for owners who work in it |
| Elected C corporation (Form 8832) | Form 1120 (IRS Publication 3402) | Form 1099-DIV for any dividends paid |
Single-member LLC: the owner’s Schedule C file
A one-owner LLC with no election does not file an income tax return of its own (IRS Publication 3402). The owner reports its income and costs on Schedule C, and figures self-employment tax on Schedule SE (IRS Publication 3402). The file looks like a sole owner’s file, with one twist: the LLC is still a separate entity for employment tax and certain excise taxes (IRS Publication 3402).
That twist matters if the LLC has staff. Payroll returns go out under the LLC’s own EIN, so ask for those filings even though the profit sits on the owner’s Form 1040. For the rest, ask for the bank and card statements of the LLC’s accounts and the receipts for its costs.
Multi-member LLC: the partnership file
A partnership return needs more than a profit figure. The operating agreement is the contract among the members that sets ownership shares, capital, how profit and loss are split and any guaranteed payments. The preparer builds every Schedule K-1 from it, so it belongs at the top of the file with any amendment made during the year.
Ask also for a capital ledger: what each member put in and took out during the year. A capital account is the running total of what a member put in, plus their share of profit, minus what they took out. Draws are not write-offs, but payments to a member for work, set by the agreement, are guaranteed payments and are listed apart. A partnership that answers yes to question 4 on Schedule B may skip the balance sheet schedules (Form 1065 instructions (2025)).
Form 7004 extends the time to file Form 1065, and it must be filed by the regular due date (Form 1065 instructions (2025)). Collect the papers early in the year, since members wait on their K-1s to file their own returns. The partnership return checklist covers the rest of a Form 1065 file.
Write-offs every LLC can claim, and their records
Whatever the status, the deductions are ordinary business costs: rent, software, insurance, contract labor, legal and accounting fees, travel and the business share of a car or phone. Each one needs a receipt or invoice, and the bank and card statements that show it was paid. The costs of forming the LLC, such as state filing fees and the lawyer who drafted the agreement, are organizational costs with their own first-year limit.
When the LLC pays a designer or a bookkeeper, it is the payer, so it collects a Form W-9 and files the 1099s. A designer paid $900 in 2025 needed a Form 1099-NEC; one paid $900 in 2026 does not (Forms 1099-MISC and 1099-NEC instructions, 2025) (Forms 1099-MISC and 1099-NEC instructions (rev. 12/2026)). The 1099 contractor checklist gives the line for each form and year.
A common myth is that an LLC lets you run personal costs through the business. It does not: personal, living and family expenses are not business costs, whatever the entity (IRS Publication 334 (2025)). Mark charges such as a family trip on the business card, so they come out of the books before the return is prepared.
S election, owner pay and state papers
An LLC taxed as an S corporation must pay owners who work in it a reasonable salary before it makes other distributions (IRS, S corporation compensation). The IRS can treat a distribution as wages if the pay is too low (IRS, S corporation compensation). So that file also needs payroll records and the owner’s W-2, and the S corporation checklist lists the shareholder basis papers.
Beneficial ownership reports no longer apply to LLCs formed in the United States. Under FinCEN’s final rule, U.S. companies are exempt and do not file BOI reports; only certain foreign companies registered to do business here must report (FinCEN, BOI reporting). Keep the state annual report and fee receipts instead, since your state may charge a yearly LLC tax or fee.
Questions people ask
What paperwork do I need to file my LLC taxes?
Start with the document that shows how the LLC is taxed: the EIN letter, plus any Form 8832 or Form 2553 acceptance. Then gather the prior return, bank and card statements, receipts, contractor forms and, for a multi-member LLC, the operating agreement and capital records (IRS Publication 3402).
Can I run personal expenses through my LLC?
No. An LLC deducts only costs of the business. Personal, living and family expenses are not deductible as business costs, whatever the entity (IRS Publication 334 (2025)). Mark personal charges on the business statements so they come out of the books.
When are LLC tax returns due?
A multi-member LLC files Form 1065 by the 15th day of the third month after its year ends, which is March 15 for a calendar year, and Form 7004 extends it (Form 1065 instructions (2025)). A single-member LLC with no election files no return of its own (IRS Publication 3402).
Can an LLC change how it is taxed every year?
No. After an LLC elects to change its classification, it generally cannot elect again for 60 months from the effective date (IRS Publication 3402).
Does my LLC still need to file a BOI report?
Not if it was formed in the United States. Under FinCEN’s final rule, U.S. companies are exempt from beneficial ownership reporting, and only certain foreign companies registered to do business in the U.S. must report (FinCEN, BOI reporting).
