What's the cheapest way to get a small business return done?

An EA or smaller CPA firm for a clean Schedule C or single-member LLC runs $300 to $1,000. The math changes once you add an S-corp election, multi-state filing, or messy records.

Do I need monthly bookkeeping or just year-end work?

Year-end-only works for very simple businesses (one bank account, few transactions). For most businesses with employees, inventory, or sales tax, monthly bookkeeping costs less in total than catching up at year-end.

What does a fractional CFO add over a CPA?

Strategic financial work: budgeting, forecasting, fundraising support, board reporting, KPI design. CPAs handle compliance; fractional CFOs handle planning. Many CPA firms now offer both.

How do I budget for CPA fees in year one?

For a new small business, budget $2,000 to $6,000 in the first year for entity setup, bookkeeping setup, payroll setup, and the first return. Year two usually settles into a predictable monthly retainer.

Are CPA fees deductible?

Yes, fees related to your business are fully deductible as a business expense. Fees for personal tax preparation are not deductible on your federal return (a Tax Cuts and Jobs Act change). State rules vary.

Small business CPA fees vary more by entity type and condition of records than by firm size. This page breaks down the typical cost by service so you can budget realistically and compare quotes against the market.

By entity type

Entity choice is the biggest single driver of return preparation fees. Verified 2026 ranges:

Service	Typical 2026 range
CPA hourly rate	$150 to $450 / hour
Schedule C (sole proprietor)	$190 to $800
Single-member LLC return	$300 to $1,500
S-corporation return (1120-S)	$1,200 to $3,500
Partnership return (1065)	$1,000 to $5,000+
C-corporation return (1120)	$1,500 to $4,000+
Monthly bookkeeping (small business)	$190 to $800 / month
Monthly advisory retainer Complex engagements range $1,000 to $6,000+ per month.	$250 to $900 / month

Disorganized records ("shoebox" engagements) typically increase fees by 1.5x to 2.0x.
Each additional K-1 partner usually adds roughly $300 to $500.
Ranges reflect entity type, bookkeeping state, and complexity. Quotes vary by region and CPA experience.

Full table with methodology lives in the 2026 CPA Compass Fee Benchmark.

A single-member LLC taxed as a sole proprietor is reported on Schedule C and prices like a sole prop return ($190 to $800). Elect S-corp status and the cost jumps to $1,200 to $3,500 because the 1120-S is a separate corporate return with K-1s. The tax savings from the S-corp election usually exceed the added fee once net income clears roughly $80,000, but the comparison should be specific to your numbers. See our S-corp election guide.

Monthly bookkeeping

For a small business with standard volume (a few hundred transactions, payroll for under 10 employees, single entity, no inventory), monthly bookkeeping runs $190 to $800. Adding inventory, multi-entity consolidation, or sales tax compliance across many states pushes the range to $800 to $2,500. Many small businesses use a bookkeeper for monthly close at the lower end and a CPA only at year-end for the return and planning, which usually saves 20% to 40% over a CPA-only engagement.

Advisory retainers

A monthly advisory retainer with a CPA typically runs $400 to $1,500 for a small business. This usually covers monthly review of financials, quarterly tax estimate calculations, response to year-round questions, and a year-end planning meeting. Fractional CFO engagements at small business scale add $2,000 to $5,000 per month and include budgeting, forecasting, KPI reporting, and ad-hoc analysis.

Year-one setup

New businesses have a one-time setup cost in addition to ongoing fees:

Entity formation and EIN: $300 to $1,000 (often handled by an attorney).
S-corp election (Form 2553) if applicable: $300 to $750.
QuickBooks or accounting system setup: $500 to $2,000.
Payroll system setup: $200 to $600.
Sales tax registration in applicable states: $150 to $500 per state.

Most CPAs bundle some of this into a flat first-year fee. Ask for an itemized estimate before engaging.

What drives the price within the range

Number of states. Each additional state adds $150 to $400 to the return.
Number of K-1s. Each additional partner on a partnership return adds $300 to $500.
Bookkeeping condition. Reconciled QuickBooks at the low end. Bank statements in a shoebox at 1.5x to 2x.
Inventory. Cost of goods sold accounting (especially for ecommerce) takes meaningful time.
Industry. Specialized industries (crypto, cannabis, healthcare, real estate) carry premium pricing.
Geography. Major metros sit in the upper third of every range.

How to reduce the fee

Keep books current monthly, not yearly. Catch-up bookkeeping is the single biggest fee multiplier.
Use one bank account and one credit card per entity. Mixed personal and business accounts double reconciliation time.
Provide year-end documents in one organized package, not 20 emails over three weeks.
Pick the right entity for your scale, not the most prestigious one. A C-corp adds compliance cost a single-member LLC doesn't.
