Small Business Accountant Fees: Tax Returns, Bookkeeping and Retainers
How accountants price small business work: entity returns, bookkeeping, payroll and monthly retainers, with a cost-building worksheet and questions to ask first.
A small business owner usually pays an accountant for several separate services: preparing the business and personal returns, keeping the books, handling payroll and sales tax filings, and giving planning advice. Each has its own pricing logic, and the total depends far more on the condition of your bookkeeping and the number of transactions than on the size of your revenue. The best way to budget is to price each service separately, then decide whether a bundled monthly retainer is better.
This guide breaks down how those pieces are billed and how to compare quotes that bundle them differently.
Start with your entity type
The type of entity determines which returns have to be filed and who files them.
| Entity | Federal return | Notes |
|---|---|---|
| Sole proprietor or single-member LLC (default) | Schedule C with Form 1040 | Business income reported on your personal return |
| Partnership or multi-member LLC (default) | Form 1065 plus Schedule K-1s | Owners report their share on personal returns |
| S corporation | Form 1120-S plus Schedule K-1s | Owners who work in the business must generally receive reasonable payroll |
| C corporation | Form 1120 | Taxed at the entity level; dividends are taxed again on personal returns |
Entity returns for partnerships and S corporations are generally due earlier than personal returns, on the 15th day of the third month after year end (March 15 for calendar-year entities), although extensions are available. Preparers often price entity returns higher than a Schedule C because they involve more forms, balance sheet reporting and K-1s, and then they also prepare the owners' personal returns.
Bookkeeping versus tax preparation
Bookkeeping records and categorizes transactions. Tax preparation turns those records into returns. If your books are messy, an accountant who prepares your return must either do the cleanup at an hourly rate or send you away to fix them. Many small businesses spend less overall by paying a bookkeeper at a lower rate, or using accounting software carefully, then paying the CPA or EA only for tax work.
Bookkeeping is often priced:
- monthly, by transaction volume or number of accounts,
- hourly for cleanup or catch-up work,
- as a flat project fee for prior months.
Ask what the bookkeeping price assumes: the number of bank and card accounts, the volume of transactions, whether reconciliations are included and whether you provide receipts.
Payroll and sales tax
If you have employees, you must deposit payroll taxes and file Form 941 (generally quarterly) and Form 940 annually, plus state filings, and issue W-2s. Many owners outsource payroll to a payroll provider or accountant, typically priced per payroll run or per employee per month. Sales tax filings, where required, can be priced per return or per state. Contractors who receive $600 or more in a year generally must be sent a Form 1099-NEC, and reporting thresholds are changing for some payments, so confirm the current threshold on IRS.gov. These small services add up, so ask whether they are bundled.
The monthly retainer
A retainer bundles routine services for a recurring fee. A typical package might include monthly bookkeeping review, quarterly estimated tax calculations, year-end tax return preparation and a few advisory calls. The advantage is predictability and a relationship with a professional who knows your business. The risk is paying for services you do not use or running into extra charges for items outside the scope.
Questions that clarify a retainer:
- Which returns are included (business, personal, state, sales tax)?
- Is bookkeeping included, and at what transaction volume?
- How many advisory hours or calls are included?
- What is the charge for catching up prior months or years?
- How do I end the arrangement and get my records back?
Build your own estimate
You can build a rough annual budget with simple arithmetic. List each service, assign hours or a monthly cost from written quotes and add them up.
Worked example (illustrative numbers only): a one-person S corporation expects 8 hours for the entity return and the owner's personal return at $200 to $300 per hour, bookkeeping at $300 per month, and payroll at $60 per month.
- Tax preparation: 8 x $200 = $1,600 low, 8 x $300 = $2,400 high.
- Bookkeeping: 12 x $300 = $3,600.
- Payroll: 12 x $60 = $720.
- Total: $1,600 + $3,600 + $720 = $5,920 low, and $2,400 + $3,600 + $720 = $6,720 high.
These figures are placeholders to show the arithmetic, not typical prices. The fee estimator covers the tax preparation portion.
Tax planning is worth pricing separately
Choices such as entity structure, owner compensation, retirement plan contributions, equipment purchases and timing of income can change your tax bill. Many accountants charge hourly for planning calls or include a few in a retainer. Planning is most valuable before year end, when decisions can still be made. A return prepared after year end can only report what already happened.
When to hire and when to keep it simple
- Very early stage, few transactions: you may use accounting software and tax software, then get a one-time review.
- Growing revenue, employees or multiple states: a CPA or EA relationship, with bookkeeping support, is usually worth it.
- Entity decisions or sale of a business: hire a CPA or tax attorney early.

Mistakes to avoid
- Mixing personal and business spending in the same account, which increases bookkeeping time.
- Waiting until March to hand over a year of unreconciled transactions.
- Hiring a preparer without asking about experience in your industry.
- Assuming a retainer includes IRS notice response or audit support. Confirm it in writing.
Frequently asked questions
Do I need a CPA for my small business?
Not necessarily. A CPA or an enrolled agent with business experience can do the job. Choose by experience with your entity type and industry.
Is bookkeeping tax deductible?
Business bookkeeping and accounting fees are generally deductible as ordinary business expenses, but confirm treatment with your preparer.
How often should I meet my accountant?
At least once a year before year end for planning, and more often if you are growing, hiring or buying equipment.
Will my fee go up if I have more revenue?
It can, because revenue often correlates with complexity, but the fee should be tied to work and risk, not revenue alone.
