What It Costs to Have an LLC's Tax Return Prepared Depends Almost Entirely on How the LLC Is Taxed

The most common pricing question small-business owners ask — "how much to do my LLC's taxes" — has no answer until the second question is asked: taxed as what? The LLC is a state-law entity that the federal tax system does not recognize as a category; it is classified by default and by election into one of four returns, and each return is a different amount of work. Single-member LLC, disregarded (the default): no separate return — the business reports on Schedule C of the owner's Form 1040, with self-employment tax on Schedule SE, and the preparation cost is the Schedule C's cost added to the owner's personal return (the personal-return cost guide): the income reconciliation, the expense categorization, depreciation on equipment and vehicles, the home office computation, and the estimated-tax planning — a modest increment for a clean set of books and a large one for a shoebox; the state may impose an LLC fee or franchise tax with its own filing (California's annual LLC tax and fee, Texas's franchise report, New York's filing fee) that adds a form. Multi-member LLC, partnership (the default): a separate Form 1065 partnership return with a Schedule K-1 for each member, plus each member's personal return reporting the K-1 — the 1065 requires a balance sheet (for most partnerships), capital account tracking under the tax-basis method, allocations per the operating agreement, and the K-1 package; the preparation cost is a separate return's cost (typically several times a Schedule C's increment) plus the K-1 reporting on each member's 1040, with multi-state partnerships adding state partnership returns and nonresident withholding. LLC electing S corporation status: Form 1120-S with K-1s, plus the payroll the S corporation must run for owner-employees (reasonable compensation on a W-2, quarterly payroll filings, year-end W-2s and the annual reconciliation), plus the members' personal returns — the most expensive small-business classification to maintain, because the return, the payroll system, and the shareholder-basis tracking are three ongoing workstreams; the S election's value (self-employment tax saved on the profit above reasonable compensation) is real above a profit level that varies by industry and state, and the classification decision is precisely the comparison of that saving against the added preparation and payroll cost — a comparison that lands in the low-to-mid five figures of profit for most service businesses, below which the S corporation costs more than it saves. LLC electing C corporation status: Form 1120, corporate-level tax, dividend reporting for distributions, and the owner's personal return — a return of similar complexity to the 1120-S without the K-1 pass-through, chosen for reasons (outside investors, retained earnings at the corporate rate, qualified small business stock) that are usually not preparation-cost reasons. What moves the price within each classification: the books — a reconciled general ledger from accounting software is the starting point for any business return; a bank statement export is bookkeeping first (priced by the hour, before the return); fixed assets — depreciation schedules for equipment, vehicles, and improvements are maintained year over year, and a business with many assets or a cost segregation study carries more; inventory — businesses with inventory add cost-of-goods computations and, above the small-business exception, accounting-method constraints; states — each state with nexus is another return, and partnership and S corporation state returns are more work than individual ones; owners — each additional member or shareholder is another K-1, basis schedule, and often another state; and first-year items — the initial return of any entity carries setup (the balance sheet's opening entries, the election filings, the accounting method choices) that recurring years don't. The classification decision, priced honestly: a service business earning modest profit stays a disregarded LLC (Schedule C) — cheapest to prepare, no payroll, the self-employment tax simply paid; a business whose profit clears the threshold where S corporation payroll-tax savings exceed the added return-and-payroll cost elects S status — and the threshold is computed, not assumed, with the reasonable-compensation requirement (the IRS expects owner-employees to be paid a market salary before distributions) as the constraint that limits the saving; a business with multiple owners is a partnership by default and considers the S election on the same arithmetic plus the eligibility rules (no nonresident alien members — the S corporation eligibility guide — and a single class of stock); and a business raising outside capital or retaining earnings considers the C corporation for its own reasons. The recurring mistake: electing S status on a US$40,000 profit business because "everyone says S corps save taxes" — the payroll cost, the 1120-S fee, and the reasonable-compensation requirement consume the saving and then some; the election that makes sense at US$120,000 of profit is a cost at US$40,000.

Key takeaways

• There is no LLC return: the LLC files as a disregarded entity (Schedule C on the owner's 1040), a partnership (Form 1065 with K-1s), an S corporation (Form 1120-S with K-1s and mandatory payroll), or a C corporation (Form 1120) — and the preparation cost follows the classification.
• Cheapest to most expensive to maintain: Schedule C (an increment to the personal return) → Form 1065 (a separate return plus K-1 reporting) → Form 1120-S (a separate return, payroll, and basis tracking) → Form 1120 (a corporate return plus dividend reporting).
• Within each, the price moves on: the books (reconciled ledger vs bank export), fixed assets, inventory, states, number of owners, and first-year setup.
• The S election is an arithmetic decision: payroll-tax saving above reasonable compensation versus the added return, payroll, and basis-tracking cost — positive above a profit threshold in the low-to-mid five figures for most service businesses, negative below it.
• State fees and filings add a form: California's LLC tax and fee, Texas's franchise report, New York's filing fee, and multi-state partnership returns are part of the real cost.
• Books first, always: a business return quoted on a reconciled ledger is the form count; one quoted on a shoebox is bookkeeping plus the form count.

Pricing your LLC's return

Identify the classification (default or elected). Count the returns it produces (the entity return if any, each owner's personal return, each state). Rate the books. List the fixed assets, inventory, and owners. Add first-year setup if applicable. Then — for a profitable single-owner or multi-owner service business — run the S election arithmetic before assuming the election is a saving: reasonable compensation, the payroll cost, the 1120-S fee, and the self-employment tax actually avoided. Fairlight's business return and payroll fees are on the pricing page; the classification decision is the conversation that should precede the quote.

Worked example

Three LLCs, same revenue, different costs. LLC one: a single-member consulting LLC, US$65,000 profit, disregarded — Schedule C on the owner's 1040, clean books from accounting software, no state entity return in her state; the business adds a modest increment to her personal return's cost and she pays self-employment tax on the profit. LLC two: the same business at US$160,000 profit, having elected S status — Form 1120-S, a payroll for her US$90,000 reasonable salary (quarterly 941s, W-2, state unemployment), shareholder-basis tracking, and her 1040 with the K-1; her preparation-and-payroll cost is several times LLC one's, and her self-employment tax saving on the US$70,000 of profit above salary exceeds it by a comfortable margin — the election earns its keep at this profit level. LLC three: a two-member design LLC, US$110,000 profit, a partnership by default — Form 1065 with two K-1s, tax-basis capital accounts, allocations per the operating agreement, and two personal returns with K-1s; the members ask about S status, run the arithmetic (two reasonable salaries against US$110,000 of profit leave little above-salary income to shelter), and stay a partnership — the cheaper classification for their numbers. Same revenue band, three classifications, three cost structures — and in each case the cost followed the return type, not the business.

Practitioner note

The LLC pricing question is a classification question in disguise, and the classification is arithmetic: Schedule C is cheapest, the S corporation is the most expensive to maintain, and the election pays for itself only above a profit threshold that reasonable compensation sets. We price the return from the classification and the books, and we run the S election numbers before anyone files Form 2553 — because the small-profit S corporation that 'saves taxes' is the most common self-inflicted cost we unwind.
