What Licenses Does a Solo Attorney Practice Need?

2026-08-21

Discover the essential licenses and permits for a solo law practice, including bar admission, business licenses, and trust account requirements, with practical steps.

Starting a solo law practice requires more than a law degree and a bar card. You must secure specific licenses and permits at the federal, state, and local levels. This guide outlines the exact licenses you need, what they cost, and how to get them, so you can practice legally and avoid penalties.

1. Bar Admission in Your State

The most critical license is your law license. You must be admitted to the bar in the state where you practice. If you plan to practice in multiple states, you may need to be admitted in each, either by exam or reciprocity. Fees vary: for example, in California, the initial bar fee is $150, plus annual dues of $438 (2026). In New York, the admission fee is $375, with annual registration of $375. Check your state bar’s website for exact figures. If you are already licensed, ensure your status is active and in good standing.

2. Business Licenses and Permits

Even as a solo, you must register your business with the appropriate authorities. The specific licenses depend on your location and business structure.

State-Level Registration

Professional Corporation or LLC: Most states require attorneys to form a professional entity (PC or PLLC) if they incorporate. For example, in Texas, a PLLC filing fee is $300. In Florida, a PA (Professional Association) costs $125. If you operate as a sole proprietorship, you may not need to file with the state, but a DBA (Doing Business As) registration is often required if you use a trade name. DBA fees range from $10 to $100.
State Tax Registration: You need a state tax ID (often called a sales tax permit) if you sell goods or services subject to sales tax. Legal services are generally exempt, but you may still need to register for employer taxes if you have employees. Check your state’s revenue department.

Local Licenses

City or County Business License: Many municipalities require a general business license. For example, Los Angeles charges $80 to $500 annually based on gross receipts. New York City requires a Business Certificate (DBA) for $100. Contact your city clerk or county office to determine requirements.
Zoning and Home Occupation Permit: If you work from home, you may need a home occupation permit to ensure your practice complies with local zoning. Fees are typically $50 to $200.

3. Professional Liability Insurance (Malpractice Insurance)

While not a license, malpractice insurance is mandatory in some states and strongly recommended everywhere. It protects you if a client sues for negligence. Premiums for solo attorneys range from $1,500 to $5,000 per year, depending on your practice area and location. For example, a solo in Illinois might pay $2,500 annually for a $100,000/$300,000 policy. Some states, like Oregon, require proof of insurance or a bond to practice. Check your state’s requirements.

4. Trust Account Requirements (IOLTA)

If you handle client funds, you must open an Interest on Lawyers’ Trust Account (IOLTA) account. This is not a license, but you must register the account with your state’s IOLTA program. Most states require you to report the account number and bank. Registration is usually free, but you must comply with record-keeping rules. For example, in New York, you must file an IOLTA compliance form annually. Failure to register can result in disciplinary action.

5. Federal Employer Identification Number (EIN)

If you have employees or operate as a corporation or partnership, you need an EIN from the IRS. This is free and can be obtained online in minutes. Even as a solo, if you form an LLC or PC, you’ll need an EIN to open a business bank account. Apply at IRS.gov.

6. Continuing Legal Education (CLE) Compliance

While not a one-time license, CLE is an ongoing requirement to maintain your law license. Most states require a certain number of credits every year or two. For example, California requires 25 hours every three years, including 4 hours of ethics. Fees for CLE courses range from $20 to $200 per course. Track your credits carefully to avoid suspension.

7. Specialized Licenses for Practice Areas

Depending on your niche, you may need additional certifications. For example:

Patent attorneys: Must pass the USPTO patent bar and pay a $335 registration fee.
Immigration attorneys: No extra license, but you must be in good standing with the bar.
Tax attorneys: May need an IRS PTIN (Preparer Tax Identification Number) if you prepare tax returns, which costs $30 annually.

Practical Steps to Get Licensed This Week

Verify your bar status: Log into your state bar portal and confirm your active status and CLE compliance.
Check local requirements: Call your city or county clerk to ask about business licenses and zoning permits.
Register your business entity: If you haven’t formed an LLC or PC, decide on a structure and file online with your state’s secretary of state. Fees vary, but budget $100 to $500.
Apply for an EIN: Go to IRS.gov and complete the online application. It takes 10 minutes and is free.
Open an IOLTA account: Contact your bank to set up an IOLTA account and register it with your state’s IOLTA program.
Purchase malpractice insurance: Get quotes from providers like ALPS or Lawyers Mutual. Compare coverage and costs.
