How Much Does an Accountant Cost for a Small Business?

For most small businesses, an accountant costs somewhere between $1,000 and $5,000 a year, though the range stretches in both directions depending on your entity type, how much work you hand off, and the state of your books. A clean sole proprietorship might spend around $1,000 for annual tax preparation and little else. A growing S-corp with payroll, multistate filings, and monthly bookkeeping can easily run $5,000 or more. Hourly rates for a qualified accountant or CPA typically fall between $150 and $400,¹ but hourly is only one of several ways accountants bill, and for ongoing work it is often not the cheapest.

Tax Preparation Cost by Business Type

Annual tax preparation is usually the single largest line item and the most common reason a small business owner picks up the phone. What you pay depends heavily on the entity and the return’s complexity.

Simple sole proprietorship filing a Schedule C: $200 to $800.²
Complex sole proprietorship: $1,000 to $1,500.
S-corp or partnership return (Form 1120-S or 1065): $1,000 to $2,000.
Complex C-corp or passthrough entity: $2,000 to $4,000 or more.²

Several things push those figures higher. Disorganized bookkeeping can add $500 to $1,000 because the CPA has to reconstruct records before preparing the return. Last-minute submissions during peak season can trigger surcharges of up to 20%. Multiple states, foreign income, or several owners all raise the price. CPAs billing hourly for tax work charge $150 to $500 per hour, with senior partners at larger firms at the top of that range.²

One thing to keep in mind: tax preparation fees are deductible as a business expense. IRS Publication 334 lists legal and professional fees, including tax preparation, as a deductible category.³

Total Annual Accounting Cost by Entity Structure

Tax prep is only part of the picture. When you add compliance filings, payroll, and state-level requirements, the total annual cost varies sharply by structure.

Sole proprietorship: near $0 in structural compliance costs beyond the return itself, since there are no separate entity filings.⁴
LLC in its default tax status: $0 to $800 a year, depending on state requirements. California, for example, imposes a minimum $800 franchise tax on LLCs.⁴
S-corp: $1,500 to $3,000 or more per year. That reflects the return itself ($800 to $2,000), mandatory payroll to satisfy the reasonable salary rule ($500 to $1,500 annually), and state-specific filings.⁴

The S-corp math matters if you’re considering the election. The tax savings from splitting income between salary and distributions only pay off when they exceed the added compliance costs. For businesses with net profits between $40,000 and $60,000, it’s often close to a wash.⁴

How Accountants Bill

Three pricing models cover most engagements, and knowing which one you’re looking at helps you read a quote.

Hourly rates run $150 to $400 for a qualified accountant or CPA.¹ Hourly is common for consulting, cleanup work, or projects where nobody knows the scope up front. The trade-off is unpredictability.

Fixed monthly retainers cover ongoing services like bookkeeping, payroll, and recurring tax filings. Basic bookkeeping with quarterly tax prep might run about $500 a month, though the range is wide: roughly $200 for light-touch service up to $2,500 or more for comprehensive packages.¹

Flat project fees attach a set price to a defined task. An annual corporate tax return, for instance, might carry a flat fee around $1,200.¹

Some firms combine a flat base fee with hourly charges for anything outside the agreed scope. Others price as a percentage of client revenue; accounting costs commonly run 2% to 5% of a business’s annual revenue as a rough benchmark.⁵

What Drives the Bill Up or Down

The gap between a $1,000 annual bill and a $10,000 one comes down to a handful of variables.

Location. Accountants in major metros like New York or San Francisco charge meaningfully more than those in smaller cities.¹
Credentials and experience. A CPA with twenty years in a niche practice bills more than a general accountant. Forensic accounting, international tax, and mergers and acquisitions sit at the top of the fee scale.¹
Business complexity. Multi-entity operations, inventory, multiple revenue streams, and multistate filings all take more time and expertise.¹
Record quality. Handing over clean, categorized digital records instead of a shoebox of receipts can reduce professional fees by 10% to 20%.¹
Headcount. Payroll, W-2 preparation, and employment tax filings all scale with employees.
Timing. Fees run higher during peak tax season from January through April than off-season.⁶

Bookkeeper, Accountant, or CPA

Not every task needs the most expensive professional. Matching the work to the right pay grade is one of the easier ways to control what you spend.

Bookkeepers handle daily transactional work: categorizing expenses, reconciling bank accounts, managing invoices, and preparing basic profit-and-loss statements and balance sheets. No degree or license is required, though certifications exist through groups like the National Association of Certified Public Bookkeepers. Bureau of Labor Statistics data puts the median hourly wage for bookkeeping and accounting clerks at about $23.66.⁷ Freelance bookkeepers typically charge $30 to $100 per hour.

Accountants without a CPA license can do financial analysis, tax preparation in many states, and general advisory work. They often hold a bachelor’s degree but aren’t required to pass a licensing exam.⁸

CPAs sit at the top. Beyond the credential itself, they hold privileges general accountants don’t: they can sign audit reports and represent clients before the IRS.⁷ Their hourly rates run from $150 up to $400 or more. The practical approach for most small businesses is to use a bookkeeper for routine work and reserve the CPA for tax strategy, compliance, and anything that legally requires the credential. Many owners use both.

Payroll Costs

Payroll usually shows up as its own line item, whether you use a dedicated service or bundle it in with your accountant. Standalone payroll services typically charge a monthly base fee of $20 to $150 plus $2 to $15 per employee per month. When a CPA or accounting firm runs payroll, it’s often a flat monthly fee ranging from roughly $40 to over $100 depending on employee count and complexity.⁹ More frequent pay runs, filings in multiple jurisdictions, and extras like retirement reporting or garnishments push the price up.

Bundling payroll with your accounting firm can come with a discount. One firm advertises up to $120 per month off for clients who combine accounting and payroll.¹⁰

Online Bookkeeping Services

Online bookkeeping platforms pair cloud software with remote professionals and generally price more predictably than a traditional hourly firm. Some of the current price points:

Pilot: starts at $169 per month for bookkeeping; CFO advisory starts at $1,750 per month.¹¹
Bench: core bookkeeping starts at $399 per month, or $299 per month billed annually; bookkeeping-plus-tax packages start at $599 per month on an annual plan.¹²
1-800Accountant: starting at $209 per month.¹³
Xendoo: starting at $395 per month, focused on e-commerce with weekly reconciliation.¹³
Bookkeeper360: starts at $399 per month for bookkeeping; CFO advisory starts at $2,000 per month.¹³
Block Advisors: tiered plans from $19 per month for self-service software up to $309 per month for a premium plan with a dedicated accountant, accrual accounting, and sales tax filing.¹⁴

Outsourced bookkeeping more broadly runs $500 to $7,500 per month depending on scope and business size, compared to $3,000 to $4,500 per month plus benefits for a full-time in-house bookkeeper.¹⁵ A business spending $400 to $600 a month on virtual bookkeeping lands at roughly $5,000 to $7,000 a year, well below the fully loaded cost of a salaried employee.

DIY Software Versus Hiring a Professional

Accounting software handles a lot of the daily work on its own. Basic cloud-based plans with invoicing and expense tracking run $15 to $50 per month. Platforms like Zoho Books and Wave offer free tiers below certain revenue thresholds.¹⁶

Software does the transactional work well: recording sales, tracking expenses, generating invoices, reconciling bank feeds. It doesn’t tell you whether an S-corp election makes sense, flag a missed deduction, or represent you in an audit. Many owners settle in the middle: software for routine bookkeeping, a professional for tax prep, compliance, and advice.

Time is part of the calculation. Forty percent of small business owners spend over 80 hours a year on tax preparation alone.¹⁷ At that volume the question is whether those hours pay better elsewhere.

Fractional CFO Services

If your business has outgrown standard tax and bookkeeping help but can’t justify a full-time CFO (a role that can command $250,000 or more a year), fractional CFO services occupy the middle. Engagements typically cost $3,000 to $12,000 per month, with early- to mid-stage companies averaging $5,000 to $8,000.¹⁸ The work covers cash flow, financial modeling, fundraising support, and board reporting, and pricing scales with revenue, transaction volume, number of entities and accounts, and how often you need the CFO’s attention. Most small businesses will never need this tier.

How to Bring the Cost Down

The single biggest lever is the quality of your records. Accountants bill for time, and time spent cleaning up messy books adds nothing to your business. Clean digital records maintained through accounting software can cut professional fees by 10% to 20%.¹

A few other moves help. Bundling services with one provider often earns a discount. Defining a clear scope of work up front prevents surprise bills. For tasks that don’t need a CPA (basic bookkeeping, invoicing, expense categorization), using software or a bookkeeper at a lower rate frees the CPA’s hours for the work that actually needs the credential. And when comparing quotes, check that you’re looking at equivalent scopes: a low monthly retainer that excludes tax prep and payroll usually costs more in total than a higher retainer that bundles everything in.
