How Much Does a CPA Cost: Breaking Down the Price

Learn what CPAs typically cost for solopreneurs, what actually drives those fees up or down, and how to decide whether DIY, a traditional CPA, or an automated system is the right fit for you.

If you run a business-of-one, tax season can feel like you’re writing big checks just to stay out of trouble. You know you should get help, but it’s hard to tell whether you’re paying for real strategy or cleanup that a better system could’ve handled.

And when you hear that some solopreneurs spend a few hundred dollars on tax prep while others spend a few thousand, it’s natural to ask: where should I actually land? On top of that, S Corps have a reputation for being “too complex” or “too expensive” unless you have a full finance team, which means many solos leave significant tax savings on the table.

What Does a CPA Do for Your Business‑of‑One?

Before you think about price, it helps to be clear on what you’re buying.

For solopreneurs, a certified public accountant (CPA) typically helps with:

• Tax preparation: Filing your federal and state returns (and sometimes local returns), including your business schedules and your personal return.

• Tax planning: Helping you decide on the right business structure, estimate quarterly taxes, and plan ahead so you’re not surprised by your bill.

• Financial questions: Answering one‑off questions about deductions, retirement contributions, estimated payments, and what to do when something changes (like going full‑time or adding a new income stream).

You can do most of this yourself with software or an automated platform. The real value of a CPA is their judgment, especially once your income, entity type, or state footprint gets more complex.

If you want that kind of guidance without building a finance team, Lettuce gives businesses-of-one an automated S Corp system with solo-focused tax experts behind it.

Average Ranges for CPA Fees

There’s no single price tag that fits every situation, but recent CPA fee surveys and 2025 pricing guides point to some clear ballparks for businesses‑of‑one.

For most solopreneurs working with a CPA firm, costs typically fall into three buckets:

• Simple sole proprietor or single‑member LLC (Schedule C, one state): For a combined personal return (Form 1040) plus Schedule C and one state return, many solopreneurs see roughly $300–$800 per year, assuming their books are relatively clean and they file in one state.

• Profitable solopreneur running, or ready for, an S Corp: For an S Corp return (Form 1120‑S + K‑1) plus your personal return and state(s), it’s common to see $800–$2,000+ per year, depending on your city, how tidy your records are, and whether you need extra planning time.

• Established S Corp with multi‑state clients and heavier complexity: Once you add multiple state returns, more 1099s, or regular planning calls, annual CPA spend for a business‑of‑one can easily land around $1,500–$3,000+.

These are typical ranges, not quotes. Your actual cost will depend on certain factors.

What Drives Your CPA Costs

CPA pricing isn’t random. For solopreneurs, the number you see on a quote usually comes down to four levers:

1. Who You Hire

CPAs in high-cost-of-living areas usually charge more than those in smaller cities or rural regions, as their own rent, salaries, and overhead are higher, and that flows through to their hourly rates and fixed fees.

On top of that, a CPA who specializes in solo consultants, online businesses, or S Corps may charge more than a generalist, but can often save you more because they understand your exact mix of income streams, platforms, and tax decisions.

2. How Complex Your Business Is

The more moving parts your business has, the more your CPA will charge.

Common complexity drivers include:

• Multiple income sources (client work, royalties, creator income, platform payouts)

• More than one schedule or entity (Schedule C, 1120‑S, 1065)

• Payroll, owners’ distributions, or fringe benefits

• Multi‑state or international income

You’ll pay less for a one‑time 1040 + Schedule C than for ongoing services that include tax planning, quarterly check‑ins, financial statements, and audit support. As soon as you layer in S Corp payroll, multi‑state clients, or lender‑ready statements, you’re in a higher complexity and higher fee tier.

That’s also the point where an all‑in system like Lettuce can start replacing a lot of the manual work and vendor sprawl.

3. Your Entity Type (Schedule C vs. S Corp vs. Partnership)

Entity type is one of the biggest drivers of cost.

• A straightforward sole proprietor or single‑member LLC (Schedule C) is the lightest lift.

• An S Corp adds payroll, an additional tax return, reasonable compensation, distributions, and K‑1s.

• A partnership or multi‑member LLC taxed as a partnership adds another layer of complexity around ownership and profit splits.

That extra work is why S Corp and partnership returns tend to cost more than Schedule C, but it’s also why they often unlock meaningful self‑employment tax savings once profits are high enough.

4. How Organized and Early You Are

This is the lever you control the most.

When your CPA has to reconcile 12 months of bank statements, fix mis‑categorized expenses, or untangle a mixed personal/business account, they’re effectively becoming your bookkeeper.

Firms and surveys note that messy records often trigger noticeable surcharges, often around $150 or more in extra fees, compared with clients who show up with reconciled, categorized books.

Timing matters, too. If you drop everything on your CPA in late March, they may charge rush or peak‑season premiums or have to push you onto extension. Getting organized early, ideally in January or February, keeps your bills lower, your stress down, and gives you more time for planning instead of patching problems.

CPA or DIY: What’s Right for You?

There’s no one right setup for every solopreneur—you’re really choosing how much of the work you want to own yourself versus how much you want handled for you.

You might lean DIY + basic software if:

• Your business profit is under ~$50,000.

• You operate in one state with simple income and expenses.

• You’re comfortable reading IRS instructions, following tax software prompts, and double‑checking the details yourself.

You’re probably ready for a done‑for‑you system if:

• Your profit is approaching or past ~$60,000, and you haven’t evaluated an S Corp.

• You’re tired of guessing on quarterly taxes or setting money aside by feel.

• You’re juggling multiple income streams, platforms, or states.

• You’re spending 10+ hours a month on bookkeeping and still feel behind.

Traditional CPAs will always have a role, especially for complex, one‑off situations or multi‑entity setups.

Lettuce focuses on the sweet spot in the middle: businesses‑of‑one that want S Corp‑level tax savings and an organized back office, without building a finance team or stitching six separate tools together.

How Much Does a CPA Cost: Frequently Asked Questions (FAQs)

Getting clear on CPA costs puts you back in control of your financial decisions. Here's what freelancers and solopreneurs need to know about hourly rates, value, and tax rules, straight facts that help you make the system work for you.

How much does a CPA cost per hour?

Most firms bill around $150–$400+ per hour for small‑business tax and advisory work, based on NSA fee surveys and common pricing benchmarks. That rate has to cover salaries, benefits, overhead, and profit, which is why it’s much higher than the ~$38–$40/hour median wage you see in BLS data.

Is hiring a CPA worth it for solopreneurs?

It depends on your profit and complexity. Under ~$50,000 in annual profit with simple, single‑state income, a well‑chosen tool or automated system can be enough, but once you’re around $60,000+ in profit or running an S Corp, having a CPA or a platform like Lettuce in your corner can unlock significant tax savings and reduce risk.

Can I deduct CPA fees on my taxes?

Generally, business‑related fees for tax prep, bookkeeping, and tax advice are deductible as business expenses, such as on Schedule C for a sole proprietor. Purely personal tax prep fees are not currently deductible as itemized deductions, so it’s smart to pay business work from your business account and have your preparer separate business vs. personal services on the invoice.

When should I move from DIY to a CPA or to Lettuce?

It’s time to upgrade when you’re guessing on quarterly taxes, your profit is approaching or past $60,000, you’re dealing with multi‑state clients, or you’re spending serious time on bookkeeping and still feel behind. At that point, the tax savings, penalty avoidance, and time you get back usually outweigh the cost of a CPA or a purpose‑built system like Lettuce, and you can sanity‑check the numbers with the Lettuce Tax Calculator.

What can I do right now to reduce CPA fees?

Start by separating business and personal money, keeping your books up to date each month, and sending documents well before deadlines. From there, ask for fixed pricing instead of open‑ended hourly work and automate as much as possible, things like transaction imports, categorization, and tax tracking. So your CPA spends time on strategy, not cleanup.

Stop Overpaying: Get Big-Firm Strategy For A Solo Price

CPA costs typically range from about $300–$800 for simple returns up to $2,500+ for more complex S Corp setups. The more organized and proactive you are, clean books, clear records, and no last‑minute scramble, the less you’ll spend on pure cleanup and catch‑up.

Smart automation is what turns that from a good intention into your default. The best tax solutions for solopreneurs always combine automation with expert oversight, so you get big‑firm strategy without big‑firm retainers.
