Choosing a Startup CPA: What Founders Should Actually Ask

Most founders hire an accountant the way they hire a plumber — when something has gone visibly wrong. The tax deadline is next week, or an investor has asked for financials that do not exist, or a letter has arrived from a state revenue department about a filing nobody knew was required.

By then the choice is made under pressure, and the person hired is whoever answers the phone. That is how companies end up restating numbers halfway through diligence, or discovering in year four that they never filed in three states where they have employees.

This guide covers what accounting work a startup actually needs, how the roles differ, the specific filings that catch early companies, and the questions to ask before you engage anyone.

1. Four Different Jobs, Frequently Confused

"We need an accountant" describes at least four distinct services, with different skills, different costs, and different people.

Bookkeeping

Recording transactions, reconciling bank and card accounts, categorising expenses, running accounts payable and receivable, closing the month. This is a process job. It can be outsourced cheaply, and it should be, but it must be done consistently — everything downstream depends on it.

Tax compliance

Federal and state income tax returns, franchise tax, sales and use tax, payroll tax registrations, 1099 filings, and any international obligations. This is technical, deadline-driven, and genuinely requires a CPA or enrolled agent who works with companies like yours.

Audit and assurance

An independent examination of your financial statements resulting in an opinion. Performed by a separate firm operating under independence rules — an auditor cannot audit books they prepared. Most startups do not need one until a lender, a large customer, a Regulation Crowdfunding threshold, or a later-stage investor requires it.

Strategic finance

Forecasting, scenario modelling, pricing analysis, board reporting, cash management, fundraising support. This is a CFO function, not an accounting one, and hiring a tax CPA expecting it is the single most common mismatch.

A small startup can reasonably buy the first two from one firm. Confusing the second with the fourth causes most of the disappointment founders report about their accountants.

2. Cash Versus Accrual, and Why It Is Not a Preference

Cash accounting records revenue when money arrives and expenses when money leaves. Accrual accounting records them when they are earned and incurred, regardless of timing.

For a startup selling annual contracts, the difference is enormous. Collect $120,000 up front for a twelve-month contract and cash accounting shows $120,000 of revenue this month. Accrual accounting shows $10,000 a month for twelve months, with the rest sitting as deferred revenue — a liability, because you owe the service.

Investors, lenders and acquirers all work in accrual. Every SaaS metric that matters assumes it. Presenting cash-basis numbers means either converting them under time pressure during diligence, or having your figures quietly recalculated by someone who now trusts you slightly less.

Many startups file taxes on a cash basis for legitimate reasons while maintaining accrual books for management and investor reporting. That is fine and normal. What is not fine is having no accrual books at all when a term sheet arrives. If you are getting your numbers in order, the metrics investors underwrite are all built on accrual foundations.

3. The Filings That Catch Startups

Income tax is rarely the problem for a company with no income. These are.

Delaware franchise tax

Almost every US startup is a Delaware C corporation, and Delaware charges an annual franchise tax due 1 March, plus an annual report. The default calculation method — authorised shares — produces alarming bills for companies with millions of authorised shares. The alternative assumed par value capital method usually produces a dramatically lower figure for an early-stage company.

Founders receive a bill for tens of thousands of dollars, panic, and pay it. A competent CPA recalculates using the other method. Check the Delaware Division of Corporations guidance, and make sure whoever handles your filings knows to do this.

Multi-state payroll and nexus

A remote employee in another state generally creates payroll tax registration and withholding obligations there, and often income tax nexus for the company. Five remote hires can mean five state registrations, five sets of filings, and five sets of penalties if missed. This is now the most common compliance failure in early-stage companies and it accumulates quietly.

Sales tax on software

Since the Wayfair decision, economic nexus rules mean you can owe sales tax in a state where you have no physical presence, based purely on sales volume or transaction count. Whether SaaS is taxable varies by state — some tax it, some do not, some tax it only if delivered in particular ways. Uncollected sales tax becomes a liability that surfaces in diligence and can reduce a purchase price directly.

R&D tax credits

Qualifying small businesses can apply federal research credits against payroll taxes rather than income tax — meaning a pre-revenue company can convert engineering spend into actual cash. Many startups never claim it. Study the mechanics before assuming you do not qualify; software development frequently does.

Section 174 capitalisation

Rules requiring research and experimental expenditures to be capitalised and amortised rather than deducted immediately created large, counterintuitive taxable income for loss-making startups from 2022 onward, with subsequent legislative changes altering the treatment again. This area has moved repeatedly. Ask your CPA specifically how they are treating your R&D spend and what it does to your current-year liability — the answer should not be a blank look.

1099s and contractor classification

Contractors paid above the reporting threshold need 1099s. Beyond the filing, misclassifying employees as contractors creates back-tax and penalty exposure, and it is a standard diligence question.

4. What Good Looks Like

• A monthly close that actually closes. Books finalised within 10 to 15 business days of month end, with a consistent package: profit and loss, balance sheet, cash flow, and a burn and runway summary.
• A clean chart of accounts that separates cost of revenue from operating expenses properly — which is what makes gross margin meaningful.
• Deferred revenue tracked correctly if you bill annually.
• A compliance calendar covering every jurisdiction you touch, delivered to you rather than held privately.
• Clean equity accounting, including stock compensation expense, so your books reconcile to your cap table.
• Books an auditor could pick up without a six-week clean-up project.

5. Questions to Ask Before Engaging

• How many venture-backed startups do you serve, and at what stages? A firm whose clients are restaurants and dental practices is excellent at something, but it is not this.
• Who does the actual work? The partner in the meeting is not the person closing your books.
• What is included, and what is billed hourly? Get the boundary in writing. "Answering investor diligence questions" is often out of scope and can be expensive at exactly the wrong moment.
• Which software do you work in, and do we own the file? You should have admin access to your own accounting system. Firms that hold your books hostage in their own environment create real switching costs.
• How do you handle multi-state registrations? If the answer is vague, you will find out the hard way.
• Have you supported a company through a Series A diligence process? Ask what was requested and how quickly it was produced.
• Do you also provide 409A valuations or audit? If yes, understand the independence implications before bundling — see below.

6. The Independence Question

It is tempting to buy everything from one provider. Be careful at two specific boundaries.

Audit independence. A firm that prepares your books generally cannot audit them. If you anticipate needing an audit, keep the relationships separate from the start rather than switching providers under deadline.

409A valuations. The safe harbour depends on the valuation being performed by a qualified independent appraiser. Bundling it with your general accountant can work, but confirm the independence position explicitly — the consequences of a defective 409A fall on your employees, as our guide to option pools and 409A valuations explains.

7. Cost and When to Upgrade

Costs vary widely by geography and complexity, but the shape is consistent: outsourced bookkeeping is a monthly retainer scaling with transaction volume; tax preparation is an annual fee scaling with entity complexity and state count; audits are a step-change in cost and effort.

The signals it is time to move to a larger firm:

• You are approaching an audit requirement
• You have international entities, transfer pricing, or foreign employees
• Your current provider cannot answer a diligence request within days
• You have crossed roughly $10 million in revenue, where complexity rises sharply
• You are contemplating a sale, where quality-of-earnings work becomes central

Switch between fiscal years where possible, and never during a live financing.

Frequently Asked Questions

Do we need a CPA from day one?

You need bookkeeping from the first transaction and tax compliance from the first filing deadline. Whether that requires a CPA specifically depends on complexity. What you should not do is leave a year of transactions uncategorised and hope to reconstruct them later — that reconstruction costs several times what doing it properly would have.

Can we just use accounting software and do it ourselves?

For the first few months, plausibly. The failure mode is not the software; it is that founders stop maintaining it when the business gets busy, and the gap is discovered when it matters most. Outsourced bookkeeping is inexpensive relative to the cost of a bad close.

What is a quality of earnings report?

A buy-side or sell-side analysis that normalises earnings for one-off items, accounting policy choices and pro forma adjustments. Buyers commission them in almost every acquisition. Sellers increasingly commission their own in advance to control the narrative and avoid surprises.

How do we handle equity compensation in the books?

Stock-based compensation expense must be recognised under US GAAP, based on grant-date fair value. Many small startups ignore it and then have to restate. If you grant options, this needs to be in your books from the beginning.

Our accountant does not understand SaaS metrics. Is that a problem?

Not necessarily — that is finance work, not accounting. But your books must be structured so the metrics can be derived: revenue by customer and product, cost of revenue separated properly, and churn identifiable. Ask for that structure explicitly.

The Bottom Line

Good accounting is invisible until a term sheet arrives, and then it is the difference between a diligence process that takes three weeks and one that takes three months and shakes the buyer's confidence.

Hire for the job you actually have, keep audit and valuation independence in mind, and make sure someone owns a compliance calendar covering every state you have touched. The failures in this area are almost never dramatic — they are quiet, cumulative, and expensive to unwind.
