What Law Firms Should Know About Bookkeeping: Staying Tax Compliant with CPA Guidance

By Carlton M., CPA | Watchmen Consulting

When it comes to running a successful law practice, most attorneys don’t dream of managing financial ledgers or reconciling bank accounts. However, bookkeeping is a foundational part of building a sustainable and compliant law firm. If ignored or mishandled, it can lead to major headaches—from tax penalties to ethical violations.

Here’s what every law firm should know about bookkeeping, and how partnering with a CPA-led service can save time, money, and reduce risk.

1. Trust Accounting is Not Optional—It’s Mandatory

If your firm handles client funds, you’re required to follow strict IOLTA (Interest on Lawyers’ Trust Accounts) rules. Every transaction must be tracked, and commingling funds (even accidentally) can lead to disciplinary action.

🔍 Tip: You should be doing regular trust reconciliations—monthly at minimum. A good bookkeeping system will flag any discrepancies before they become a liability.

2. Your Chart of Accounts Should Be Customized

Law firms have unique income and expense categories—court filing fees, bar dues, client reimbursements, etc. If you’re using a generic chart of accounts, your reports won’t give you the insight you need, and tax season will be messy.

💡 Tip: A customized chart of accounts helps you track profitability per partner, practice area, or matter—and makes tax filing faster.

3. You Must Track Partner Draws, Distributions, and Payroll Separately

Law firms structured as partnerships or S-Corps need to carefully separate owner distributions, guaranteed payments, and payroll. These distinctions have tax consequences and reporting obligations (think: K-1s vs. W-2s).

🧾 Tip: Partner compensation should be tracked outside regular expense accounts. Don’t just “write a check and call it good.”

4. Billable Hours Are Useless Without Clean Books

You might be billing $300/hour, but if your overhead is unclear or your accounts are off, you won’t know your actual profit per case. Without accurate books, your cash flow can deceive you.

📊 Tip: Pair your time tracking system (like Clio or MyCase) with proper accounting software—then review monthly financials with your CPA.

5. Taxes are Easier When You’re Proactive

Many law firms scramble at year-end, only to realize they missed deductible expenses or underpaid estimated taxes. With proper monthly bookkeeping and tax planning, you can optimize deductions, contribute to retirement plans, and stay out of trouble.

💼 Tip: Work with a CPA who can do both your bookkeeping and your tax planning—it ensures consistency and strategic oversight.

6. The Importance of Regular Financial Reviews

Regular financial reviews are crucial for maintaining the health of your law firm. These reviews allow you to assess your financial position and make informed decisions.

Why Schedule Regular Reviews?

By scheduling regular reviews, you can catch discrepancies early. This proactive approach helps you avoid potential issues down the line. Plus, it gives you a clearer picture of your firm’s financial health.

How Often Should You Review?

Aim for monthly reviews. This frequency allows you to stay on top of your finances without feeling overwhelmed. During these reviews, analyze your income, expenses, and overall cash flow.

7. Embrace Technology for Better Bookkeeping

In today’s digital age, leveraging technology can streamline your bookkeeping processes.

Tools to Consider

Consider using cloud-based accounting software. These tools can automate many tasks, reducing the time you spend on bookkeeping. They also provide real-time insights into your financial situation.

Benefits of Automation

Automation minimizes human error and ensures your records are always up to date. This can save you time and reduce stress, allowing you to focus on your legal practice.
