Quick Summary

Starting a law firm is exciting and overwhelming in equal measure. There’s the business registration, the malpractice insurance, the office setup, the marketing, and somewhere in the middle of all of it, the accounting. Most new law firm owners treat accounting as something they’ll figure out later. That’s a mistake. The financial decisions made in the first weeks of a law firm’s existence set the foundation for everything that follows: compliance, profitability, tax preparation, and the firm’s ability to grow. This guide covers what new law firms need to know about accounting before they take their first client.

Highlights

• The accounting decisions made when starting a law firm are harder to undo than most new attorneys realize
• An IOLTA trust account is required the moment you receive client funds, not after you’re established
• QuickBooks out of the box is not configured for law firm use and needs to be set up correctly before recording transactions
• Time tracking from the very first matter protects billable revenue from being lost forever
• Getting the accounting foundation right early is significantly less expensive than fixing it later

The Mistake Most New Law Firms Make

New attorneys starting their own practice are focused on getting clients, delivering great work, and building their reputation. Accounting feels like something that can wait until there’s more money coming in and more time to deal with it.

By the time most new law firms get around to setting up their accounting properly, they’ve already made decisions that are hard to undo. They’ve been running transactions through the wrong accounts. They’ve received client funds without a proper trust account in place. They’ve lost track of billable hours that will never be recovered. And they’ve built habits around their finances that take real effort to change.

The accounting setup for a law firm is not something that can be retrofitted easily once the firm is up and running. It needs to be right before the first client walks in the door, not because the IRS is watching, but because the state bar is.

Register With Your Secretary of State and Get Your EIN

Before any accounting setup happens, the business needs to be legally established. That starts with registering the firm as a business entity with your state’s Secretary of State office.

The registration process varies by state but generally involves filing formation documents, paying a registration fee, and in some states publishing a notice of formation.

Once the business is registered, the firm needs an Employer Identification Number from the IRS. An EIN is required to open business bank accounts, hire employees, and file business tax returns. It’s also what separates the firm’s financial identity from the attorney’s personal identity, which matters for both liability and accounting purposes.

If the firm plans to hire employees, even just one administrative staff member, additional registration is required. The firm needs to register with its state’s department of revenue for state income tax withholding and with the state’s workforce agency for unemployment insurance. These registrations need to happen before the first paycheck is issued, not after. Payroll tax obligations begin with the first employee and the penalties for missing deposits or filings accumulate quickly.

Start With the Right Business Structure

The business structure affects how income is taxed, how partner compensation is handled, and what the firm’s accounting obligations look like.

This is a decision worth making deliberately rather than by default. Many attorneys start as sole proprietors because it’s the path of least resistance, then realize later that a different structure would have been more advantageous. Changing structures after the fact creates accounting and tax complications that are avoidable with some upfront planning.

The business structure also determines what the firm’s accounting system needs to track. A solo practitioner’s accounting looks different from a two-partner LLC, which looks different from a professional corporation. Getting the structure right first means the accounting can be built to fit it correctly.

Open the Right Bank Accounts Immediately

One of the most important early steps for any new law firm is opening the right bank accounts and opening them before any client funds are received.

At minimum a new law firm needs two bank accounts. An operating account for the firm’s own money, where revenue is deposited once earned and from which business expenses are paid. And an IOLTA trust account for client funds that have been received but not yet earned.

The IOLTA account is not optional. The moment a new law firm receives a client retainer, a settlement deposit, or any other funds that belong to a client rather than to the firm, those funds need to go into a properly established IOLTA account. Depositing client funds into the operating account, even temporarily, is commingling, which is a bar rule violation regardless of intent.

Many new attorneys don’t realize this until they’ve already received their first retainer. By then the violation has already occurred. Opening the IOLTA account before taking the first client eliminates this risk entirely.

Set Up QuickBooks Correctly Before Recording Transactions

QuickBooks Online is the right accounting platform for most small law firms. It’s cloud-based, widely supported, integrates with the major legal practice management platforms, and scales as the firm grows.

But QuickBooks out of the box is not ready for law firm use. The default chart of accounts is built for a generic small business. It doesn’t include trust liability accounts, fee income by practice area, client cost advances, or the other categories that law firm accounting requires.

A new law firm that sets up QuickBooks using the default template and starts recording transactions is building its financial records on a foundation that doesn’t reflect how a legal practice actually operates. Fixing that foundation after a year of transactions have been recorded is significantly more work than building it correctly before the first entry is made.

The QuickBooks setup for a new law firm should include a law firm specific chart of accounts, correctly configured IOLTA trust accounts recorded as both bank accounts and liabilities, income categories by practice area, and the integration with whatever practice management platform the firm uses for billing and time tracking.

Choose a Practice Management Platform Early

The accounting system and the practice management system need to work together before the first matter is opened. Choosing a practice management platform early and integrating it with QuickBooks means billing data, trust transactions, and client payments flow correctly into the accounting system without manual entry.

A platform like Clio Manage is built specifically for law firms and handles time tracking, billing, matter management, and client communications in one place. It integrates natively with QuickBooks Online, which means data flows between the two systems automatically.

The alternative is managing billing in one place and accounting in another, manually reconciling the two, and hoping nothing falls through the cracks. For a solo attorney or small firm without dedicated administrative support, that approach creates more work and more risk than it’s worth.

Track Time From Your Very First Matter

Billable time that isn’t recorded is revenue that’s gone forever. There’s no way to reconstruct time accurately after the fact, and the hours that go unrecorded in the early days of a practice add up faster than most new attorneys expect.

Time tracking from the first matter also establishes the habit and the system that the firm will rely on as it grows. Attorneys who start tracking time consistently early maintain that discipline as their caseload increases. Those who put it off tend to continue putting it off.

Beyond billing, matter level time tracking is what makes it possible to understand profitability at the case level. A flat fee that seemed reasonable at intake looks different after the attorney can see how many hours it actually required. Without time tracking that comparison is impossible.

Understand Your Bar Obligations Before You Need Them

Every state bar has financial recordkeeping requirements that apply to law firms the moment they begin practicing. Trust account management, reconciliation requirements, record retention obligations, and documentation standards are all bar requirements, not suggestions.

New attorneys often assume these obligations only apply to established firms or to practices that handle large amounts of client money. They don’t. The rules apply from the first client and the first dollar of client funds received.

Understanding what your state bar requires before you need to comply with it is significantly easier than trying to get compliant after the fact. The requirements aren’t complicated once you understand them. But they do require systems and habits that need to be established early.

FAQ

When do I need to open an IOLTA account? Before you receive any client funds. The moment a client pays a retainer, advance, or any other payment that hasn’t yet been earned, those funds need to go into a properly established IOLTA trust account. Opening the account before your first client eliminates the risk of inadvertently commingling funds.

Do I need QuickBooks right away or can I start with a spreadsheet? You can start with a spreadsheet but you’ll regret it. The longer a firm operates without a proper accounting system, the more transactions need to be reconstructed when the system is finally set up. Starting with QuickBooks configured correctly for law firm use means your records are accurate and compliant from the start.

What practice management software should a new law firm use? There are several solid options but a platform like Clio Manage is widely used, well supported, and integrates natively with QuickBooks Online. For a new firm building its systems, choosing a platform that works seamlessly with your accounting system is worth prioritizing.

How much should a new law firm budget for accounting? That depends on the size and complexity of the firm but accounting is not an area where new law firms should be looking for the cheapest option. The cost of setting up the accounting incorrectly and fixing it later is significantly higher than the cost of getting it right.

Do I need an accountant right away or can I handle it myself? Many new attorneys try to handle their own bookkeeping in the early days. The risk is that law firm accounting has specific requirements around trust accounts and bar compliance that most people without a law firm accounting background aren’t fully aware of. By the time the problems show up they’ve often been accumulating for months.
