Market analysis
The customers are owner-run businesses and self-employed people who need a tax return, a plan for next year's tax and someone to call in between — plus households with rental property or a side business, and the bookkeepers and advisers who send them.
- Owner-run businesses that want a tax return, a tax plan and someone to call during the year
- Self-employed people and freelancers who owe quarterly estimates and dread April
- Households with rental property, stock compensation or a side business
- Bookkeepers and financial advisers who need a CPA to send their clients to
Marketing strategy
Most new clients will arrive by referral and word of mouth — from clients, bankers, attorneys and financial advisers — and Google decides between the firms they're given: a searcher for “CPA near me” in February compares Google Business Profiles, reviews and a website that shows the firm's services, credentials and a way to book.
- Referrals from clients, bankers, attorneys and financial advisers — 57% of businesses found their accountant through a peer referral in a 2025 survey, 3% through advertising
- Google Business Profile and Google — “CPA near me” and “tax preparer” plus your city peak from January to April
- Word of mouth from business clients, who talk to other owners about their accountant
- One industry niche, known well enough that its owners find you and recommend you
- A website with your services, credentials, starting fees and a booking request form
Operations plan
The partners prepare and review the work themselves in year one, plan each tax season in November, move every client document through a secure portal under a written security plan, and track realization — hours worked against the fee charged — so underpriced clients are repriced the next year.
- An engagement letter for every client, every year, with the fee and the scope in writing
- Tax season planned in November: organizers sent, deadlines booked, extensions decided early
- Monthly accounting and advisory clients billed all year, so the summer pays the rent
- Client documents through a secure portal, under the written information security plan federal law requires
- A second review of every return before it is filed

Typical range to start an accounting firm in the US: $1,430–$21,946. Your list is what you decided to spend — replace estimates with real quotes as you get them. Website and Google Business Profile: Your Zarla plan includes the website — a call button at the top, your services and starting prices, and a booking request form — and walks you through your Google Business Profile; a designer typically charges $2,500 or more to build one — a planning range. Invoicing, booking and client records, first year: Invoicing, online booking and a client list come with your Zarla plan; your tax and accounting software is separate.
Financial plan
The numbers below come from your own startup list and typical monthly costs for a small accounting firm in the US. Running costs are modest and steady while fees arrive in a spring rush, so the plan's real question is how much year-round work covers the months between tax seasons — and the cash reserve covers the first of them.
Typical monthly operating costs for an accounting firm: $227–$2,857 a month, before the owner's own pay.
At $22,000 in monthly sales, Harborview Tax & Accounting would clear $19,143–$21,773 a month before owner pay and tax, and recover the $10,139 startup budget in roughly 1 month.
| Cost | Typical range |
|---|---|
| Tax software, spread across the year | $32–$208 |
| Professional liability (and cyber) insurance | $45–$125 |
| Practice-management and client portal software | $0–$74 |
| Invoicing, booking and client records (included with Zarla) | $0–$50 |
| Office or coworking space | $0–$1,500 |
| Phone, internet, secure backups and continuing education | $100–$400 |
| Marketing, society dues and referral lunches | $50–$500 |
US ranges for a small operation; replace with your own figures as you learn them. Lines marked (included with Zarla) are what those tools cost separately — with Zarla they are part of one monthly plan.
Risks and honest downsides
Every accounting firm plan should say out loud what can go wrong. For Harborview Tax & Accounting, the real risks are:
- Most of a new firm's revenue arrives between January and April, and the rest of the year still has to pay the rent
- A missed deadline or an error on a return means penalties the client will expect the firm to cover
- Taking every client in year one fills tax season with low-fee returns that crowd out better work
- Clients who pay only after the return is filed stretch cash in the slowest months
- Holding Social Security numbers and bank records makes the firm a target for data theft — the written security plan is the law, not a nicety
Licenses, permits and insurance
What Harborview Tax & Accounting needs before it can legally trade in the US. Rules vary by state and city — confirm each item with your local licensing office and an accountant.
- A CPA license, and a state firm permit for a CPA firm — In Texas a licensed firm needs a majority of its ownership held by certificate holders; in California the CPA certificate is $250 to apply and $400 for the permit, and a firm's registration $250 plus $520; in Florida the firm license is $145 ($45 for a sole proprietor) and the CPA's $50 then $100 every two years; in New York the license and first registration are $427 and a firm using the CPA name registers every three years; in Washington the license is $330 then $230 and a sole proprietorship with no employees pays no firm fee. Check your own board's firm page.
- A PTIN for every preparer, and an EFIN to e-file — In the US anyone paid to prepare, or to help prepare, a federal tax return needs a Preparer Tax Identification Number — $18.75 a year — and the firm needs an EFIN to e-file, which costs nothing but takes a suitability check, so apply before the season (IRS).
- Business registration and the professional entity your state requires — In the US form the PLLC, professional corporation or LLC your board allows — $40 in Kentucky, $300 in Texas, $70 plus a $20 statement of information in California, where every LLC owes $800 a year — and get the free EIN from the IRS.
- A written information security plan for client tax data — In the US the IRS says federal law requires tax and accounting professionals to create and maintain a written information security plan; the IRS's Publication 5708 is the template and the FTC Safeguards Rule is the law behind it.
- Accountants professional liability insurance — In the US no board checked requires it, but a penalty from a missed deadline or a costly error is a claim against the firm, and many clients and referral partners ask for proof — $45 a month at Insureon's median, with cyber cover at $80 for a firm holding Social Security numbers.
- Continuing professional education to keep the license — In the US each state board sets the hours a CPA must complete to renew, and enrolled agents renew with the IRS; Becker's one-year subscriptions run $329 to $799 and AICPA membership $0 to $1,020 a year by tier.
