Small Business Accountant Cost Per Year: Is Your Bill Fair?

No federal rule sets what an accountant charges a small business, so a bill can only be tested against the work it lists: the returns, state filings and payroll it covers. Business type, payroll, states and the condition of your books drive the price. Compare quotes line by line, and read the engagement letter before paying for extra time.

Who this is for

  • Sole proprietors, LLC owners, partnerships and S or C corporations reading a yearly accountant bill or quote
  • Owners whose fee rose, who are billed for emails and calls, or who hold two quotes that are not alike

Not covered here

  • A price list or market range: no federal rule sets accountant fees
  • The monthly bookkeeping price and what a monthly service includes
  • An S corporation's payroll and Form 1120-S bill, or a startup's Form 1120 bill, in depth
  • Choosing or switching accountants, and asking the IRS to remove a penalty

Is there a standard yearly price for a small business accountant?

No. Federal rules do not set what an accountant charges a small business, so this page gives no price range. What the government fixes is the work: which returns a business must file, when, and what a late or missed filing costs. A yearly bill is the price of that list of filings plus the condition of the books behind it.

A case stops being simple when the fee rose and the filings did not, when the quote does not say which returns, states and payroll filings it covers, or when the books need work before a return can be prepared. A partnership or S corporation, payroll, more than one state and earlier years unfiled each add filings that a quote has to name.

Gather before judging a bill or a quote:

  • The engagement letter.
  • The last two invoices.
  • The returns filed for the last year.
  • A list of every filing the firm handles for you: federal, state, payroll and sales tax.

What is inside a yearly accountant bill?

A yearly bill bundles some or all of seven jobs. A quote that says only "tax preparation" does not show which ones are in.

JobWhat it coversWhat sets the amount of work
Federal returnSchedule C with Form 1040, Form 1065, Form 1120-S or Form 1120Business type and schedules, in the next section
State returnsA return in each state where the business must fileNumber of states; each sets its own forms and dates
PayrollDeposits, Form 941 each quarter, Form 940 and Forms W-2 each yearEmployees, pay frequency and, for a corporation, whether the working owner is on payroll
Sales taxA return for each state, on the schedule that state assignsNumber of states and how often each requires a return
BookkeepingRecording and reconciling the year so the return starts from finished booksAccounts, transactions and how far behind the books are
Owner's personal returnForm 1040 carrying a Schedule K-1, the owner's share of the business income, from a partnership or S corporationA separate return; a quote may price it apart or leave it out
AdvicePlanning, entity questions, notices and ordinary questionsHours; often outside a flat fee

An employer who paid wages subject to withholding, or to social security and Medicare tax, must generally file Form 941 every quarter even with no tax to report, unless the IRS has notified it that it can file Form 944 once a year instead. The employer stays responsible for deposits and filings even when someone else does the work (Publication 15). If withheld income tax or the employee's share of social security and Medicare tax goes undeposited and the business cannot pay it, the trust fund recovery penalty, equal to the unpaid tax, can be assessed personally against each person the IRS finds responsible for paying it over who acted willfully (IRS: trust fund recovery penalty).

Sales tax is a state tax, so each state decides who registers and how often they file. In Texas, for example, the Comptroller tells a taxpayer after its permit is approved whether it files monthly or quarterly, and yearly filers exist too (Texas Comptroller). For the monthly books price, see bookkeeping cost per month; for what a monthly service includes, see what a monthly bookkeeping service includes.

How does the type of business change the return work?

The business's tax classification decides the federal return, and the return decides how much work the year is. A domestic LLC with one member is by default part of its owner's return, and one with two or more members is by default a partnership. Either can elect to be taxed as a corporation on Form 8832, and a corporation can elect S status on Form 2553 (IRS: LLC; IRS: S corporations). Who signs and the deadlines are in how LLCs are taxed.

Business typeFederal returnWhat it addsCalendar-year due date
Sole proprietor, or an individual's one-member LLC by defaultSchedule C with Form 1040 (Schedule C instructions)Schedule SE for self-employment tax; the business is part of the owner's personal return, but for payroll tax a one-member LLC is still a separate entityApril 15
Partnership, or LLC with two or more members by defaultForm 1065 with a Schedule K-1 for each partner (Form 1065 instructions)One K-1 per partnerMarch 15
S corporationForm 1120-S with a Schedule K-1 for each shareholder (Form 1120-S instructions)One K-1 per shareholder; a shareholder who works in the business must be paid reasonable compensation before non-wage distributions, so payroll follows (IRS)March 15
C corporationForm 1120 (Form 1120 instructions)The corporation files and pays its own taxApril 15 of the following year

A partnership files its own return, but it is not itself subject to income tax: the partners are taxed on their shares and include them on their own returns (Form 1065 instructions). Shareholders of an S corporation likewise report the flow-through on their personal returns (IRS: S corporations). Spouses who jointly own and run an unincorporated business are generally partners and file Form 1065, with two exceptions, a qualified joint venture election and community property (Publication 334).

For an S corporation's full yearly bill, see S corporation accounting cost. For a startup C corporation, see startup accounting cost.

Retainer, flat fee or hourly: what should each cover in writing?

A fee basis is comparable only once the engagement letter says what it covers. The federal fee rule for practitioners, 31 CFR 10.27 in Treasury's Circular 230, limits fees in two ways: no unconscionable fee and, with exceptions, no contingent fee. It sets no price and no billing method, so the structure is negotiated and the letter is where it is recorded.

Fee basisThe letter should sayWhat to watch
Flat fee for the yearEach return by name and tax year, the number of K-1s, which states, whether the extension is in, and what is excludedA low fee that leaves out year-round questions, notices or amended returns
Monthly retainerThe work done each month, the hours included, whether the return is inside the retainer, and the rate beyond the hoursA retainer that covers books but prices the return again at year end
HourlyThe rate for each level of staff, the smallest time unit billed, an estimate, and your approval before it is passedOpen-ended hours, especially on books that need rebuilding

For the full list of terms to settle before signing, see what a bookkeeping engagement letter should spell out.

Why did my accountant's bill go up?

A bill rises because the work changed, because the books got harder to work from, or because the rate changed. Compare this year's list of filings with last year's before accepting any of the three.

What changedWhat it adds
A new entity or electionAn LLC that gains a second member generally files Form 1065 with K-1s; an S election adds Form 1120-S, K-1s and payroll for the working owner; a corporation files Form 1120
More statesEach state has its own returns, registrations and dates. California, for example, generally requires an LLC not taxed as a corporation and doing business there to pay an annual tax of $800 and file Form 568, with a further fee at higher California income, starting at $250,000 (California FTB). An LLC taxed as a corporation files Form 100, 100S or 100W instead (California FTB: LLC treated as a corporation)
Payroll started or grewDeposits, Form 941 each quarter, Form 940 and Forms W-2 (Publication 15)
Messier booksThe balance sheet on a return should agree with the books and records (Form 1065 instructions; Form 1120-S instructions), so gaps in the books become rebuilding work that a flat fee may not cover
A bigger scopeNotices, amended returns, extensions, earlier years and advice that a flat fee leaves out

Should I question the increase or just pay it?

Ask for the cause in writing, line by line: this year's list of filings next to last year's, and what the letter says about increases and notice. If the filings are the same and the books are no worse, a rate change is the remaining explanation to check. If a filing was added, the new quote should show it as its own line, so you can see what you are paying for.

An increase with no named cause, or a quote that will not list its filings, is the point to get the scope reviewed. Before deciding that a cheaper quote is cheaper, read the late-filing costs below.

Can my accountant charge for every email and phone call?

It depends on what the engagement letter says. The federal fee rule, 31 CFR 10.27, does not say which time a firm may bill. It bars an unconscionable fee but does not define the term, so it is a weak tool for a billing dispute. The engagement letter is the stronger tool.

A flat fee that excludes ordinary questions can cost more than its headline. The letter should say:

  • Whether questions during the year are included, and how many or how long.
  • What starts hourly billing: a call past a set length, a new issue, a notice.
  • The hourly rate, and the smallest time unit billed.
  • Whether you must approve work above an estimate.
  • Whether year-round advice is included or sold apart.

Can an accountant charge a share of my refund or my tax savings?

Generally not, and the IRS tells taxpayers to avoid it. IRS Topic 254 says to avoid preparers who base fees on a percentage of the refund or who offer to deposit all or part of the refund into their own accounts (IRS Topic 254).

Circular 230 bars a practitioner, such as an attorney, certified public accountant or enrolled agent (31 CFR 10.3), from a contingent fee for any matter before the IRS. A contingent fee is one based on whether a return position avoids challenge or is sustained; the rule names a percentage of the refund or of the taxes saved, and a promise to refund the fee if a position is challenged or not sustained. A matter before the IRS includes tax planning and advice and preparing or filing returns and claims (31 CFR 10.27).

The exceptions are narrow (31 CFR 10.27; Notice 2008-43, the IRS's interim rules):

  • Work on the IRS's examination of, or challenge to, an original return.
  • Work on the IRS's examination of, or challenge to, an amended return or refund claim filed before the written examination notice or written challenge, or no later than 120 days after the earlier of the two.
  • A claim limited to interest or penalties.
  • A whistleblower claim under section 7623.
  • A court case under the Internal Revenue Code.

One kind of work is treated differently. In 2014 a federal district court held that the IRS lacked authority under its practice-regulation statute to bar contingent fees for preparing and filing ordinary refund claims, which are claims filed after the original return and before an examination begins, and granted the plaintiff a permanent injunction (court opinion). Treasury has acknowledged that ruling in proposed rules that would replace the regulation; they are proposals, not current law (Treasury, Internal Revenue Bulletin 2025-05). Treasury also notes that many state accountancy board rules bar contingent fees for preparing an original or amended return or a refund claim, so a federal exception alone does not show an arrangement is permitted (same bulletin). The IRS warning above still stands, and a fee tied to the result still rewards a larger claim while you answer for the return.

Is my monthly CPA fee too high? How do I compare it with another quote?

A monthly fee is high or fair only against the work it lists, and no source says what a given fee should be. A monthly fee runs for twelve months, so put both quotes on a yearly basis, add the separately billed lines, then match them line by line.

LineA quote should sayIf it is missing
Federal returnWhich form, which tax year, the schedules and the number of K-1sThe return may be billed apart
State returns and sales taxWhich states for each, how often sales tax is filed, and whether owners' state returns are includedEach state may be extra
PayrollWho runs it and makes deposits, and which forms: 941 or 944, 940, W-2 and stateA missed deposit is the employer's penalty, whoever was meant to make it
BooksMonths covered, accounts reconciled, and any catch-upThe return can only be as good as the books
Owner's Form 1040In or outA separate return, priced separately
Extensions and estimatesWhether Form 7004 or Form 4868 and estimated payments are inMay be billed apart
Fee basis and extra timeFlat, retainer or hourly, and the rate outside scopeSee the questions above
Notices, amended returns, earlier years, and who signsWhether each is excluded or priced, the signer's credential, and whether the firm answers notices or only prepares the returnThese become separate jobs

A lower total that leaves out lines is not a cheaper quote for the same work. A single bundled figure can be compared only after the preparer lists what is in it.

What does a late or missed return cost on top of the fee?

A federal late-filing penalty runs from the due date, counting any extension. An extension to file is not an extension to pay, so late-payment penalties can start earlier (IRS). Both are charged on top of any accountant's fee. A quote that leaves out a required return does not remove the return; it moves the cost to a penalty.

ReturnLate-filing penalty
Schedule C with Form 1040, or Form 11205% of the unpaid tax for each month or part of a month, up to 25%, less any late-payment penalty for the same months. A return more than 60 days late has a minimum: the smaller of the tax due or $535 (IRS)
Form 1065$260 for each person who was a partner at any time in the tax year, for each month or part of a month, up to 12 months (Revenue Procedure 2025-32)
Form 1120-S$260 for each person who was a shareholder at any time in the tax year, for each month or part of a month, up to 12 months, plus the unpaid-tax penalty if tax is due (Revenue Procedure 2025-32)

The per-owner amounts and the minimum are those set for this page's tax year. A return for an earlier year carries the amount set for its own due date; the IRS lists each year's amount on its failure to file penalty page. Whether a failure was due to reasonable cause, which excuses the penalty, depends on the facts, and a state may add its own penalty. A missed year also often has to be rebuilt before the current year can be prepared, which adds to the bill. For relief and notices, see late filing and payment penalties. For several years unfiled, see catching up on unfiled business returns.

Is my accountant's work signed and returned properly?

Anyone paid to prepare a return generally must sign it, enter a preparer tax identification number (PTIN) and give you a copy (Form 1065 instructions; Form 1120-S instructions; IRS Topic 254). Confirm these when you receive the return:

  • Signature and PTIN: the filed return carries the preparer's signature and PTIN. The preparer need not enter the PTIN on your copy (IRS: credentials).
  • Never a blank form: do not sign a blank return. You remain accountable for every item, whoever prepared it (IRS Topic 254).
  • The preparer-authorization "Yes" box: on a business return it lets the IRS call the paid preparer who signed about processing questions. It does not let the preparer receive a refund check, bind you or represent you before the IRS (Form 1120-S instructions). Only attorneys, CPAs and enrolled agents have unlimited representation rights (IRS: credentials).

On leaving, a practitioner must, on request, promptly return the records you need to meet your federal tax obligations. A fee dispute generally does not excuse the delay. If state law lets the practitioner keep records during a fee dispute, the practitioner need only return those that must be attached to your return, and must give you reasonable access to review and copy the rest. Work the practitioner prepared and is holding back until it is paid for is not counted among those records (31 CFR 10.28). For the handoff itself, see switching accountants.

Example

These examples use US dollars and round numbers. They show how to read a quote, not what anything costs.

A Schedule C freelancer billed extra for emails

A freelancer with US$120,000 of revenue is quoted a US$2,000 flat fee for a Schedule C and Form 1040. During the year the firm bills another US$500 for emails and calls. The year's cost is US$2,500. A second firm quotes US$2,300 with year-round questions included, so it is the lower bill for the same work. The rate was never the problem: the first letter said "flat fee for return preparation" and nothing about questions. The letter, not the rate, needs fixing.

A two-partner LLC with rental income in two states

Two members own an LLC with US$400,000 of revenue and rental property in two states. By default it files Form 1065 with two K-1s, and each state may require its own return. Last year's quote listed one state return; this year's lists two, after a second property was bought. The added state return is one line that can explain the increase, so the quote should show each state on its own line.

If the Form 1065 had been three months late and the same two members held the LLC all year, the charge before any relief would be the per-partner amount in the penalty table above, times 2 partners, times 3 months, whatever the fee was. A small partnership can have reasonable cause presumed under Revenue Procedure 84-35: 10 or fewer partners, all individuals other than nonresident aliens (or estates), items allocated in the same proportion, and each partner's share reported on a timely filed return (IRS). The conditions and proof are in late Form 1065 penalty relief.

An S corporation owner holding a US$9,000 bundle

An S corporation owner with one shareholder is quoted US$9,000 for the year as a single figure. A second firm lists its lines:

LineAmount
Twelve months of booksUS$4,800
Payroll for the owner: four Forms 941, Form 940, Form W-2US$1,200
Form 1120-S with one K-1 and one state returnUS$2,400
SubtotalUS$8,400
Owner's Form 1040, not included aboveUS$900

The second quote is US$8,400 without the Form 1040 and US$9,300 with it. The US$9,000 quote cannot be compared until it says whether payroll, state filings and the Form 1040 are in. The line amounts are arbitrary; they show how lines add up, not what any line costs.
