How much does it really cost to start an accounting firm from scratch?

A solo CPA working from home with an existing laptop can realistically launch an accounting firm for $3,000-$5,000, covering PLLC formation, state board registration, professional liability insurance, basic tax software, and a simple website. The largest upfront costs are typically professional liability insurance ($500-$1,500/year), tax preparation software licenses ($330-$4,000/year), and legal setup ($200-$1,200 for entity formation plus engagement letter templates). Costs scale to $12,000-$20,000 when you add premium practice management software, dual monitors, professional branding, and a co-working membership. A multi-person firm with a leased office, enterprise-grade tax and audit software suites, and full insurance coverage can easily require $40,000-$60,000+ in startup capital. The good news is that accounting firms have strong recurring revenue models, so most of these costs are recovered within the first year of active client acquisition.

Do I need a CPA license to start an accounting firm?

You do not need a CPA license to start a bookkeeping or tax preparation business, but you do need one to offer attest services (audits, reviews, compilations) or to call your firm a 'CPA firm.' Tax preparers without a CPA must obtain a Preparer Tax Identification Number (PTIN) from the IRS, which is free, and some states require additional registration or licensing for non-CPA tax preparers. Enrolled agents (EAs) can represent clients before the IRS and prepare tax returns without a CPA license — the EA exam costs about $200 per part (three parts total). If you plan to offer full-service accounting including financial statement audits or reviews, you will need an active CPA license in your state of practice, which requires 150 college credit hours, passing all four CPA exam sections, and 1-2 years of supervised experience. Many successful firms start with bookkeeping and tax prep services while the owner completes CPA licensing requirements.

What accounting software do I need and how much does it cost?

At minimum, you need tax preparation software and a general ledger/bookkeeping platform. For tax preparation, Drake Tax ($330-$1,800/year) is the most affordable professional option and handles individual and business returns well. Mid-range options include Lacerte ($1,500-$4,000/year) and ProSeries ($500-$2,500/year), both from Intuit. Enterprise suites like UltraTax CS ($3,000-$8,000/year) and CCH Axcess ($5,000-$10,000+/year) are designed for larger firms with complex return volumes. For bookkeeping, QuickBooks Online Accountant is free for managing client QuickBooks files, and Xero's partner program offers similar free access. Practice management platforms like Karbon ($59/user/month), Canopy ($40-$100/user/month), or TaxDome ($50-$80/user/month) handle workflow, client communication, and document management. Budget $1,000-$3,000 in Year 1 for a solo practitioner's software stack and $5,000-$15,000 for a multi-person firm with enterprise tools.

How do I get my first accounting clients when starting from zero?

The most reliable path to your first accounting clients is your existing professional network — former colleagues, friends who own businesses, and contacts from your prior firm who may follow you (check your non-compete agreement carefully first). Announce your new practice to every business owner, attorney, and financial advisor you know, because referrals from other professionals are the top client acquisition channel for accounting firms. Join your local chamber of commerce ($200-$500/year) and attend networking events consistently; BNI and similar referral groups ($500-$1,000/year) work exceptionally well for accountants because every business needs one. Claim and optimize your Google Business Profile immediately, as 'CPA near me' and 'accountant near me' are high-intent local search queries with strong conversion rates. Offer a free initial consultation to lower the barrier, and consider partnering with bookkeepers, payroll companies, or financial advisors who can refer clients needing services they do not provide. Most new firms acquire 10-20 clients in their first tax season through a combination of personal outreach and local visibility.

Should I start my accounting firm as an LLC or PLLC?

In most states, accounting firms that provide CPA services must register as a Professional Limited Liability Company (PLLC) or Professional Corporation (PC) rather than a standard LLC. A PLLC provides the same pass-through taxation and liability protection as a standard LLC, but it satisfies state board of accountancy requirements that professional service firms be organized under professional entity statutes. Formation costs are similar — $50 to $500 in state filing fees plus $500-$800 for attorney assistance with the operating agreement. Some states (like California) do not allow LLCs for CPAs at all and require a PC. Once your net income exceeds $60,000-$80,000, consult your own CPA about electing S-Corp tax status, which can save $5,000-$15,000+ per year in self-employment taxes. The S-Corp election does not change your entity type — you remain a PLLC but file taxes as an S-Corporation. Start simple, get clients, and optimize your entity structure as revenue grows.

What insurance does an accounting firm need and what does it cost?

Every accounting firm needs three core insurance policies: professional liability (errors and omissions), general liability, and cyber liability. Professional liability insurance is non-negotiable — it covers claims that your tax work contained errors, your financial advice caused losses, or you missed a filing deadline. Premiums range from $500 to $5,000+ per year based on your services (attest work costs significantly more to insure than tax prep alone), revenue, and coverage limits ($1M/$2M aggregate is standard). The AICPA Professional Liability Insurance Program offers competitive rates for members. General liability insurance ($300-$1,500/year) covers bodily injury and property damage and is typically required by landlords and some clients. Cyber liability insurance ($300-$3,000/year) is increasingly critical because accounting firms store Social Security numbers, bank account details, and other sensitive data that makes them high-value targets for hackers. The IRS now requires all tax preparers to maintain a Written Information Security Plan (WISP), and cyber insurance helps cover breach notification costs, forensic investigation, and regulatory fines if a data incident occurs.

How Much Does It Cost to Start an Accounting Firm?

$3,000 – $60,000

An accounting firm can be launched for as little as $3,000 if you are a solo CPA working from home with existing equipment, but costs climb quickly once you add staff, lease office space, or invest in enterprise-grade tax and practice management software. The biggest cost variables are your service mix (tax preparation only vs. full-service CPA work including audit and advisory), your staffing model (solo vs. multi-person firm), and your office arrangement (home, co-working, or dedicated space). State board registration fees, continuing professional education requirements, and professional liability insurance are non-negotiable expenses that every accounting firm must budget for regardless of size. Unlike many service businesses, accounting firms also face significant recurring software costs because industry-standard tools like UltraTax, Lacerte, and CCH Axcess carry annual license fees ranging from $1,000 to $10,000+ depending on the number of returns and modules required.
