When Does a Houston Business Need a CPA vs Just a Bookkeeper?

Key Takeaways

• Under about $250,000 in revenue with no employees, a bookkeeper at $300 to $800 a month covers you. A monthly CPA retainer at that stage is wasted money.

• Between $250,000 and $1 million, keep the bookkeeper and add a seasonal CPA for the return and one or two planning sessions, roughly $2,300 to $4,700 a year.

• Past $1 million, or with employees, inventory, or multiple entities, a full CPA relationship at $750 to $2,000 a month usually pays for itself in tax savings alone.

• A bookkeeper records what happened. A CPA changes what you owe. Confusing the two is the most expensive mix-up Houston owners make.

• The trigger to upgrade is never the calendar. It is payroll, an entity change, an IRS letter, or a year where you owed more than $10,000 and did not see it coming.

The Short Answer: Three Buckets

Most Houston business owners are paying for the wrong one. Some hand $600 a month to a CPA firm for work a bookkeeper would do for $350. Others trust a $400 a month bookkeeper with tax decisions that are silently costing them five figures a year. Both mistakes come from the same place: nobody ever explained where one job ends and the other begins.

The decision comes down to two numbers: your annual revenue and how complicated your money is. Employees, inventory, multiple entities, and IRS history all add complexity. Put those two together and almost every business in this city lands in one of three buckets.

• Bucket 1, bookkeeper only: under roughly $250,000 in revenue, no employees, simple structure.

• Bucket 2, bookkeeper plus a seasonal CPA: $250,000 to $1 million, or any year an entity or payroll question shows up.

• Bucket 3, full CPA relationship: past $1 million, or any revenue level with employees, inventory, multiple entities, or an IRS problem.

What a Houston Bookkeeper Does for $300 to $800 a Month

A bookkeeper keeps the record straight. Every month they categorize transactions, reconcile your bank and credit card accounts, track what customers owe you and what you owe vendors, and hand you a profit and loss statement you can actually read. For most Houston small businesses that runs $300 to $800 a month. We broke down monthly bookkeeping costs in Houston in a separate benchmark if you want the full pricing table by business type.

Here is what a bookkeeper does not do. They do not decide whether you should elect S-corp status. They do not calculate your quarterly estimated payments. They cannot sign your return or stand between you and the IRS when a notice arrives. A great bookkeeper will flag those questions when they see them in your numbers. Answering them is a different license.

What a CPA Does That a Bookkeeper Can't

A CPA holds a state license that comes with legal authority: they can sign your returns, represent you in an audit, and advise on entity structure. But the license is not the point. The point is that a CPA works on the number before it happens. Entity elections, retirement contributions, timing of equipment purchases, paying family members through the business correctly, quarterly estimates that match this year instead of last year.

A bookkeeper records history. A CPA changes what you owe. At $150,000 in revenue that difference might be worth $2,000 a year, less than the CPA costs. At $900,000 with the wrong entity structure it is routinely worth $10,000 to $25,000. That is the entire decision in one sentence: hire a CPA when the tax savings they can document exceed their fee, and not before.

Bucket 1: Bookkeeper Only

Choose bookkeeper only if you check most of these boxes. This is the lawn care operator in Katy, the freelance designer in the Heights, the one-chair salon booth in Bellaire.

Your total accounting spend in this bucket: $300 to $500 a month for the bookkeeper, plus $400 to $900 once a year for a straightforward return. One exception: spend $300 to $500 on a single CPA consult when you form the business. One hour of entity advice at the start beats three years of unwinding the wrong structure later.

• Revenue under roughly $250,000 a year

• Sole proprietor or single-member LLC with no S-corp election

• No employees, or only 1099 contractors

• No inventory and no job costing

• Last April's tax bill did not surprise you by more than a few thousand dollars

Bucket 2: Bookkeeper Plus a Seasonal CPA

Choose the hybrid if your revenue sits between $250,000 and $1 million, or if any single one of these is true: you hired your first W-2 employee, your profit is approaching $80,000, or you are wondering whether the LLC should become an S-corp.

That last question is usually worth more than everything else combined. At $90,000 of profit, a properly run S-corp election typically saves a Houston owner $8,000 to $12,000 a year in self-employment tax. Run the sole proprietor vs LLC vs S-corp numbers before you commit, because the election also adds payroll costs and a separate return.

The spend: keep your bookkeeper at $400 to $800 a month, then pay a CPA seasonally. Figure $1,500 to $3,500 for the business return and $400 to $600 each for one or two planning sessions, one in June and one in November. Total CPA cost per year: $2,300 to $4,700. The November session alone, done before year-end while you can still act on the advice, is where most of the savings live.

Bucket 3: Full CPA Relationship

Choose a full CPA relationship if revenue has passed $1 million, or at any revenue level if you run real payroll, carry inventory, operate more than one entity, or have an open IRS issue. This is the restaurant group in Midtown, the machine shop off the Beltway, the medical practice in Sugar Land.

Payroll is the sharpest trigger on that list. The IRS treats unpaid payroll tax as theft, and the penalties reach the owner personally, not just the business. If you have employees and nobody licensed is reviewing your deposits, read what payroll tax penalties actually cost before deciding that oversight is optional.

Texas adds its own layer. There is no state income tax here, but Texas franchise tax filings still apply once your entity is registered, and the calculation method you pick can change the bill. A full relationship runs $750 to $2,000 a month and should include monthly review of the books, quarterly planning, payroll oversight, the returns themselves, and a human who answers the phone when a government letter shows up.

Side by Side: What You Pay and What You Get

Here is the whole article in one list. Prices are 2026 Houston market rates for a typical small business.

Notice the overlap in price between the top of one bucket and the bottom of the next. That is intentional. A $900 a month full-service arrangement at a small firm often costs less than a bookkeeper plus an expensive seasonal CPA billed separately. Once you are shopping in that range, compare bundles, not job titles.

• Bookkeeper only: $300 to $800 a month. You get reconciled accounts, clean monthly statements, and organized records at tax time. You do not get tax strategy, entity advice, or IRS representation. Best under $250,000 in revenue.

• Bookkeeper plus seasonal CPA: roughly $600 to $1,200 a month all-in when you spread the CPA fees across the year. You get clean books plus a professionally signed return and one or two planning sessions that usually pay for themselves. Best from $250,000 to $1 million.

• Full CPA relationship: $750 to $2,000 a month, sometimes with bookkeeping bundled in. You get monthly oversight, quarterly tax planning, payroll review, and representation if the IRS calls. Best past $1 million, or earlier with employees, inventory, or multiple entities.

How to Decide This Week

Pull two documents: last year's tax return and this year's profit and loss through last month. Then ask three questions. Is revenue on pace to pass $250,000? Is profit on pace to pass $80,000? Did anything from the complexity list show up this year: an employee, inventory, a second entity, a government letter? Zero yes answers, stay in bucket 1. One yes, move to bucket 2. Two or more, price out bucket 3.

One more thing, because our office sits in a city where thousands of businesses are family-run and bilingual. Plenty of owners in Alief, Bellaire, and Sugar Land handle the register, the schedule, and the books themselves, and the books always lose that fight. If English is your second language, the person you hire needs to explain an IRS notice in the language you think in. We wrote a guide on choosing a CPA for a Vietnamese-owned business that covers exactly what to check, and a broader list of seven questions to ask first before hiring any Houston firm.

Frequently Asked Questions

What is the difference between a bookkeeper and a CPA?

For a closer look, see In-House Bookkeeper vs Outsourced CPA in Houston: Which Costs Less.

A bookkeeper records and organizes money that already moved. They categorize transactions, reconcile bank and credit card accounts, and produce monthly financial statements. A CPA is licensed by the Texas State Board of Public Accountancy, which means they can sign tax returns, represent you in front of the IRS, and advise on entity structure and tax strategy. The practical difference: a bookkeeper tells you what happened last month, a CPA changes what you owe next April. Most Houston small businesses need the first one every month and the second one a few times a year. Paying CPA hourly rates for transaction entry is one of the most common ways local owners overspend on accounting.

How much does a bookkeeper cost in Houston in 2026?

Expect $300 to $800 a month for outsourced bookkeeping if you run under roughly 200 transactions a month with one or two bank accounts. Restaurants, contractors who need job costing, and anyone carrying inventory land higher, often $800 to $1,500. A part-time in-house bookkeeper runs $20 to $28 an hour in the Houston market, which usually costs more than outsourcing once you need more than 10 hours a month. Catch-up work bills separately, typically $50 to $90 for each month of messy books being cleaned. If someone quotes $150 a month, ask exactly which accounts they reconcile, because at that price the honest answer is usually none of them.

How much does a CPA cost for a small business in Houston?

It depends on the shape of the engagement. Seasonal work in Houston prices roughly like this in 2026: $400 to $900 for a straightforward Schedule C return, $1,200 to $2,500 for a single-member LLC with clean books, and $1,500 to $3,500 for an S-corp or partnership return. A standalone planning session runs $400 to $600. A full monthly relationship, which includes the return, quarterly planning, and someone reviewing the books, runs $750 to $2,000 a month depending on complexity. The mistake to avoid is comparing a monthly CPA fee against zero. Compare it against the tax savings a planning-focused CPA can document. If they cannot show you savings that beat the fee, stay seasonal.

Can a bookkeeper file my business taxes?

Legally, anyone with an IRS preparer tax identification number can prepare and file a return, and plenty of bookkeepers do. The gap shows up in two places. First, judgment: an S-corp return with officer compensation questions, or a partnership return with basis calculations, is easy to file wrong and expensive to fix. Second, representation: if the IRS questions the return, an unlicensed preparer has very limited rights to speak for you. A CPA, enrolled agent, or attorney can handle the whole exam without you in the room. For a simple sole proprietor return with clean books, a qualified preparer is fine. Once an entity election or employees enter the picture, have a licensed professional sign.

At what revenue level does a Houston business need a CPA?

There is no legal threshold, but the money math has clear break points. Around $250,000 in revenue, or $80,000 in profit, the potential tax savings from entity elections and planning start to exceed what a seasonal CPA charges, so add one for the return and a planning session. Around $1 million in revenue, or the day you run real payroll, the number of things that can go expensively wrong justifies a monthly relationship. Below those lines a CPA is usually a nice-to-have. One exception worth repeating: pay for one CPA consult when you form the business, whatever your revenue is. Entity structure set wrong at the start is the most expensive small decision a Houston owner makes.

Do I need a CPA if I am a sole proprietor with no employees?

Mostly no, with two exceptions. If you are a sole proprietor with no employees, no inventory, and profit comfortably under $80,000, a bookkeeper plus a competent tax preparer covers you, and a monthly CPA retainer would cost more than it saves. Exception one: book a single consult when you start the business to confirm the structure fits, usually $300 to $500. Exception two: the year your profit approaches $80,000, book a planning session, because that is where the S-corp election starts saving real money and it has to be set up before it pays. Treat the CPA like a specialist you visit at specific milestones, not a subscription you carry from day one.

Can one firm do both my bookkeeping and my CPA work?

Yes, and for a lot of Houston businesses the bundle is the best value. Many local CPA firms, ours included, run bookkeeping and tax under one roof, typically $600 to $1,500 a month depending on volume and entity type. The advantage is that the books get built with the return in mind, so year-end is a review instead of an archaeology project. Two things to check before signing. First, ask who actually does the monthly work, a staff bookkeeper is fine, but a CPA should review before anything is finalized. Second, confirm planning is included and scheduled, not theoretical. A bundle that files your return but never plans ahead is just an expensive bookkeeper.

What happens if I skip both and do my own books in QuickBooks?

It works until it doesn't, and the failure is rarely visible in the software. QuickBooks, Xero, and Wave will all happily accept miscategorized transactions, and most DIY books we take over have 15 to 30 percent of transactions in the wrong place. The damage shows up three ways: a return built on bad numbers, quarterly estimates you never calculated so April arrives with a $9,000 surprise plus underpayment penalties, and deductions you never claimed because nothing was tracked. If you are determined to DIY, spend one hour a week on it, reconcile every account every month, and pay a professional for a cleanup review once a year. Under about $100,000 in revenue that regimen can genuinely work. Past it, your hourly rate is too high for data entry.
