Do I Need an Accountant for My Small Business?

Ingrid sold handmade ceramics online for two years without an accountant, and she was right not to have one. She kept a separate business bank account, used simple bookkeeping software, set aside a share of every sale for taxes, and filed her own return with a Schedule C. It took her a couple of weekends a year. Then a single wholesale order from a home goods shop in another state turned into a standing order, a second shop followed, and by summer she was shipping to customers in more than a dozen states. One evening she read an article about sales tax economic nexus, did a rough count of her sales by state, and booked a meeting with an enrolled agent the next morning.

Wendell's story went differently. He ran a landscaping company and hired his first two employees in the spring, handling payroll himself with a spreadsheet and an online calculator. He withheld taxes from their checks correctly. He just did not deposit them on time, because he did not know the deposit schedule, and cash was tight. By fall he owed back payroll taxes, penalties, and interest, and he learned that some of that debt could follow him personally even though the business was an LLC.

Both were capable owners. The difference was that Ingrid recognized the moment her business crossed from simple to complicated, and Wendell did not. That is the real question behind "do I need an accountant." Most small businesses do not need one on day one. Almost all of them need one eventually, and the cost of getting the timing wrong is usually far higher than the fee.

What you can reasonably do yourself

If you are a sole proprietor or a single-member LLC taxed as one, with a modest number of transactions, no employees, and sales mostly in your own state, a lot of the work is genuinely doable. Plenty of owners handle it well.

You can keep your own books. Open a dedicated business account (mixing personal and business money is the single biggest source of tax-time pain), pick a simple bookkeeping app, categorize transactions weekly, and keep receipts. The IRS's own guide, Publication 583, Starting a Business and Keeping Records, explains what records you need and how long to keep them.

You can track and pay estimated taxes. If you expect to owe 1,000 dollars or more when you file, the IRS says you generally need to make quarterly estimated payments. Setting aside a fixed percentage of every payment into a separate savings account makes this painless. Missing it leads to underpayment penalties, which are avoidable.

You can file a straightforward return with good software. A Schedule C for a simple service business is well within reach for an organized owner, and Publication 334, Tax Guide for Small Business, covers the rules in plain detail.

You can handle routine 1099s. If you pay contractors, you will need to collect a W-9 and file information returns. The reporting threshold for Form 1099-NEC rose from 600 dollars to 2,000 dollars for payments made in 2026, and it will be adjusted for inflation after that. The rules are clear, and the IRS's Small Business and Self-Employed Tax Center walks through them.

Doing this yourself for a year or two has a real benefit beyond the savings: you learn how money moves through your business. Owners who understand their own books make better decisions and ask an accountant much better questions later, and checking your real numbers against a plan you keep alive becomes a habit instead of a mystery.

The triggers for a CPA or enrolled agent

At some point the work stops being bookkeeping and starts being tax strategy, compliance across jurisdictions, or representation. These are the moments when a professional usually pays for themselves.

You are considering an S corporation election

Electing S corporation status can lower self-employment tax for a profitable business, which is why it gets talked about so much. It also adds payroll, a separate business return, and a requirement to pay yourself what the IRS calls reasonable compensation before taking distributions. Timing matters as well: under the Form 2553 instructions, the election generally has to be filed no more than 2 months and 15 days after the start of the tax year it is meant to cover, or at any time during the year before. Whether the savings outweigh the added costs depends on your profit, your state, and your situation. The LLC vs S Corp tax calculator gives you a first estimate, and a CPA or enrolled agent should check it before you file anything.

You are hiring employees

This is the trigger Wendell missed. Payroll means withholding income and payroll taxes, depositing them on a set schedule, filing quarterly and annual returns, issuing W-2s, and handling state unemployment and often state income tax withholding. The taxes you withhold from employees' paychecks are held in trust for the government, and the IRS can hold the people responsible for paying them personally liable for unpaid trust fund taxes, even when the business is an LLC or corporation. At minimum, use a reputable payroll service from the first paycheck. Have a professional review your setup, especially if you are also deciding whether your first hire should be an employee or a contractor, a classification question with its own penalties.

You sell across state lines

Since the Supreme Court's 2018 decision in South Dakota v. Wayfair, states can require out-of-state sellers to collect sales tax once they pass an economic nexus threshold, even with no physical presence. Most states use 100,000 dollars in annual sales into the state, a few use higher figures, and several have recently dropped their separate transaction-count tests. The rules differ by state and change often. If you sell physical goods, or taxable services, to customers in several states, a professional who handles multi-state sales tax is worth it. The state business resources page links each state's official registration and tax agencies so you can verify the current rule.

You operate or have income in more than one state

Employees working remotely in another state, a second location, or owners living in a different state from the business all create income tax and registration obligations that are easy to miss and tedious to untangle later.

You get a letter from the IRS or your state

Many notices are routine and easy to resolve. Some are not. If a notice proposes additional tax, mentions an examination, or you do not understand what it is asking, talk to a professional before you respond. Only certain professionals can represent you: the IRS explains that CPAs, enrolled agents, and attorneys have unlimited rights to represent clients on any matter, including audits, collections, and appeals, while most other preparers have limited or no representation rights. If you are facing financial hardship or the problem is not being resolved, the Taxpayer Advocate Service is a free, independent resource inside the IRS.

Something big is changing

Bringing in a partner or investor, taking a significant loan, buying or selling equipment or property, selling the business, or converting entity types. Each has tax consequences that are much cheaper to plan for than to fix.

CPA, enrolled agent, or bookkeeper?

These are different roles, and you may need more than one.

A bookkeeper records transactions, reconciles accounts, and keeps your books clean month to month. They usually are not licensed to give tax advice, and good ones will tell you so. For many small businesses, a part-time bookkeeper is the first hire in this area.

An enrolled agent is a tax specialist licensed by the IRS, with unlimited representation rights before the IRS. Enrolled agents focus on tax preparation, planning, and resolving IRS problems, and they are often a good fit and good value for small business tax work.

A CPA is licensed by a state board and can do tax work plus broader accounting services such as financial statements, audits, and reviews, which lenders or investors sometimes require. If you need audited or reviewed financial statements, you need a CPA.

The IRS keeps a directory of federal tax return preparers with credentials, which you can use to confirm that someone holds the credential they claim.

What it costs

Fees vary by market and complexity, but current survey data gives you useful anchors. The National Association of Tax Professionals' 2025 fee study, summarized by Accounting Today, found:

Those are averages and minimums. A business return with messy books, multiple states, or payroll will cost more, sometimes considerably more. Monthly bookkeeping and payroll services are usually priced by transaction volume and number of employees, so ask for a written quote based on your actual numbers.

The cheapest way to lower your bill is to hand over clean, reconciled books. Accountants charge for time, and untangling a shoebox of mixed personal and business transactions takes a lot of it.

The mistakes that cost owners the most

The biggest is waiting until something is wrong. Owners call an accountant after the penalty letter, the missed election deadline, or the sales tax notice from a state they barely knew they sold into. Prevention costs a few hundred dollars. Cleanup can cost thousands.

Running payroll by hand is a close second, for the reason Wendell found out. The deposit rules are strict, the penalties are steep, and the personal liability is real.

Choosing a preparer on price alone is another. A cheap return from someone with no credentials and no representation rights leaves you on your own if the IRS has questions. Check credentials, and ask who will help you if you get a notice.

Then there is mixing personal and business money, which makes your books harder to keep, your deductions harder to prove, and your accountant's bill higher. Opening a dedicated business bank account is the first fix and the cheapest one.

And the quiet one: never looking at your own numbers because "the accountant handles it." Your accountant sees your business once or twice a year. You see it every day. PushStartGo's free calculators and plain-language plan help you understand your own margins, break-even, and cash, so you can spot problems between appointments and walk into each one with better questions.

Back to the order from out of state

Ingrid's meeting with the enrolled agent took an hour and cost less than one of her larger wholesale orders. She left knowing which two states she needed to register in right away, which were close to the line, and how to track it going forward. Wendell's cleanup took months and cost far more than a payroll service and an accountant would have from the start.

The answer to "do I need an accountant" is usually "not yet, but soon, and here is when." Keep clean books yourself while things are simple. Learn your own numbers. Then bring in a CPA or enrolled agent the moment you hit one of the triggers, ideally a little before.
