Accounting for law firms is far more complex than basic bookkeeping. Between managing trust accounts, maintaining compliance with state bar regulations, and keeping a close eye on profitability, law firm owners have a lot on their plate. Without specialized accounting support, even experienced attorneys can face costly mistakes and missed opportunities.
In this guide, we’ll explore best practices in accounting for law firms, including how to manage client trust accounts, track expenses accurately, and generate financial reports that support strategic growth.
Why Law Firms Struggle Without Proper Accounting
Legal professionals often face unique financial challenges. Many law firms are service-heavy but cash flow-poor, especially those working on contingency. Others find themselves growing quickly without clear financial systems in place, leading to issues with payroll, taxes, and compliance.
The most common issues include:
Commingling of trust and operating funds
Inaccurate expense categorization
Delayed or incomplete financial reporting
Lack of clarity around profitability
Without reliable accounting systems and advisors who understand the nuances of legal practice, law firms risk falling out of compliance—and leaving profit on the table.
Trust Accounting: What You Must Know to Stay Compliant
One of the most important components of accounting for law firms is proper trust accounting. Most states require IOLTA (Interest on Lawyers’ Trust Accounts) to be maintained with strict separation from operating funds. Mistakes here can result in serious ethical violations, fines, or even disbarment.
Trust Accounting Best Practices:
Maintain three-way reconciliations monthly (bank balance, ledger, and client sub-ledgers)
Never commingle client funds with your firm’s operating funds
Use practice management or accounting software designed for legal professionals
Retain detailed records for every transaction
Pro Tip
Implement workflows where funds are not transferred until services are invoiced. This protects client money and keeps your firm aligned with Bar requirements.

Managing Law Firm Expenses Strategically
Expense management is another critical pillar of accounting for law firms. Not all expenses are created equal, and accurate categorization helps with everything from tax deductions to forecasting future costs.
Common overlooked items:
Partner distributions categorized incorrectly as salary
Marketing and case acquisition costs not tracked per client
Software subscriptions going unused
Contractor vs. employee classification errors
Using a skilled advisor to create a Chart of Accounts tailored to law firm operations ensures you’re tracking the right data in the right place—saving money and improving visibility.
Financial Reporting for Growth and Decision Making
Accurate, timely financial reports are essential for law firm owners who want to scale. You need more than just profit and loss statements. You need insights.
Reports to Track Monthly:
Profit & Loss by Practice Area
Cash Flow Statement
Aged Accounts Receivable
Budget vs. Actuals
Balance Sheet with trust liabilities included
When done right, accounting for law firms goes beyond compliance. It becomes the foundation of smart decision-making and long-term profitability.
How Clean Financials Help Secure Business Loans & Credit
Many firms come to King of Kings Firm after being turned down for loans—not because they’re not successful, but because their books are unclear or outdated. Banks and credit institutions want to see:
Clean, reconciled financial statements
Cash flow projections
Profitability trends over time
Responsible handling of trust accounts
When law firms lack proper financial oversight, they often fail to qualify even when business is booming. On the other hand, firms with reliable accounting and clear metrics often qualify for higher credit limits and better loan terms.
