How Much Does Small Business Tax Preparation Cost in 2026?

Two professional associations publish fee surveys, and between them they cover most small business returns. The NATP 2025 Fee Study (November 2025) is current but reports individual returns in detail. The NSA Income and Fees study for 2020-2021 reports business returns and is the latest we could open with per-form figures. Both are averages of what preparers say they charge, not quotes.

A 2026 quote will usually land above the 2020 averages. NATP reports that 83% of preparers raise fees every one to two years, typically by 6 to 10%, and 68% plan to raise them next year (2025). We have not applied an inflation factor to the NSA figures, because no survey we opened publishes a current average for business returns.

Read the table with the respondents in mind. NATP's 2025 respondents were mostly individual-return preparers: 55% primarily prepare Form 1040 returns with common schedules and 6% primarily prepare business or fiduciary returns. Enrolled agents were 43% of respondents and CPAs 21%, and a respondent could hold more than one designation. NSA's 2020-2021 report describes a typical respondent as an enrolled agent (45%), a sole proprietor (32%) and 29 years in practice. Neither survey is a poll of firms that specialize in multi-state S corporations.

The public NATP materials we opened show business-return fees nowhere. The media highlights chart only 1040 schedules, and NATP's own guide points to a full study for exact figures. We found no 2024 or 2025 published average for a Form 1065 or Form 1120-S in the documents we opened (checked 2026-10-18). Vendor blogs often quote ranges for business returns without naming a survey, and we have not repeated figures we could not trace to a source.

What the surveys do establish is the shape of pricing. The NSA series for the Form 1120-S runs $656 in 2007, $717 in 2012, $778 in 2014, $809 in 2016, $807 in 2018 and $903 in 2020, a rise of 38% over 13 years. Business returns cost several times what a simple individual return does, and the gap comes from entity-level work.

Preparers price on judgment, and the NATP study says so. Asked what they consider when valuing a service, 94% named the complexity of the client's tax situation, 83% the time and effort required, 69% their own expertise, 49% the level of risk or liability and 46% the potential tax savings. Asked what influences their pricing decisions, 69% named the uniqueness of their expertise and 52% market rates for similar services.

Credentials move the average too. The table shows the base Form 1040 with Schedules 1 to 3 from the NATP study.

State returns add to the bill. NATP reports that a majority of preparers charge separately for state returns, either for every one or when there is more than one, and that the average preparer files for clients in 8 to 9 states. A business with owners in two states is often a three-return job before it is a business return.

Five things move the fee, in roughly the order they show up on an invoice.

First, the number of returns. An S corporation return comes with owner returns, state returns and a K-1 for each shareholder. A partnership return multiplies that.

Second, the condition of the books. A preparer who receives a reconciled ledger prepares. A preparer who receives a shoebox reconciles first, and reconciling is billable time. The NATP average set hourly rate was $182 in 2025 (7% of respondents charge one, and half of those preparers fall between $129 and $250), and NSA's survey of 2020 fees averaged $179.81 an hour for a Form 1120-S. Our catch-up bookkeeping guide covers how to fix the year before it reaches the preparer.

Third, payroll and contractors. Payroll totals on Forms 941 must tie to W-2s and to the ledger, and contractors paid $2,000 or more in 2026 need a Form 1099-NEC due February 1, 2027. The Form 1099 guide lists the rules.

Fourth, fixed assets, inventory and owner basis, which need schedules that a simple return does not.

Fifth, timing. Calendar-year 2026 returns for S corporations and partnerships are due March 15, 2027, and those for individuals and C corporations April 15, 2027 (IRS Publication 509 rule, checked 2026-10-18). Rush work before a deadline can carry a premium, so ask for the delivery date in writing.

The IRS says on its PTIN page (reviewed October 15, 2026) that anyone paid to prepare returns must have a valid 2027 PTIN before preparing them, and Treasury regulation 26 CFR 1.6695-1(b) has the preparer with primary responsibility sign the return after it is complete and before it is presented to the taxpayer. The IRS credentials page (reviewed January 29, 2026) adds that CPAs, enrolled agents and attorneys have unlimited representation rights before the IRS, while a preparer with only a PTIN has none.

That is how Finbryn frames its tax work: preparation support. Finbryn prepares the workpapers, and a credentialed signer or partner prepares, signs and files the return as preparer of record. If the IRS writes to you later, representation comes only from a named CPA partner, enrolled agent or attorney, and the engagement letter says whether that is included. Ask every provider the same question: who signs, what is their PTIN, and what happens when a notice arrives? The guide to choosing a tax preparation support provider has the full checklist.

One warning from the IRS (Tax Tip 2026-11, February 10, 2026): avoid preparers who base their fees on a percentage of your refund. Always review the return before signing, and never sign a blank or incomplete one.

These are the starting prices on Finbryn's published pricing page, checked on 2026-10-18. A starting price is not a quote: the engagement letter lists the forms, the states and who signs, and sets the final fee.

See tax preparation support, the S corporation return page and the partnership return page for what each covers. The surveys above are averages across thousands of different jobs, so compare a quote against its scope rather than against a headline number. A lower price that excludes the state returns, the extension or the estimated payments is not lower.

1. Which forms are included: the entity return, each owner's return, each state?
2. Who signs, and can I see the preparer's PTIN and credential on the IRS directory?
3. Is the fee fixed, hourly or a minimum plus complexity? NATP reports that nearly half of preparers set a minimum fee and adjust it for complexity.
4. Does the quote assume reconciled books, and what happens if the ledger needs work?
5. Are the extension, the estimated tax calculations and the 1099 filings included?
6. What happens if the IRS sends a notice, and who represents me?
7. When will the return be delivered, and what is the fee for a rush?

A quote that answers all seven in writing is comparable. One that answers three is a price for part of the job.
