How to Do Law Firm Bookkeeping? What Are Its Rules – Papillon House

Law firms are subject to unique bookkeeping mandates that reflect the nuanced relationship between attorneys and their clients, particularly regarding client funds management.
Introduction to Law Firm Bookkeeping. Effective bookkeeping goes beyond mere compliance; it’s about stewarding client resources with the utmost integrity and ensuring the financial health of your firm.

Understanding Bookkeeping and Importance of Bookkeeping for Law Firms

Bookkeeping is the systematic process of recording, categorizing, and maintaining financial transactions. In the context of a law firm, bookkeeping not only ensures the financial health and viability of the practice but also ensures compliance with various legal and ethical standards set forth by legal bodies and regulatory agencies.

Thorough financial record-keeping is not just good practice—it’s a regulatory requirement. Proper bookkeeping ensures transparency, fosters trust, and ultimately upholds the profession’s ethical standards.

Unlike traditional businesses, law firms have certain unique financial and ethical requirements, especially when it comes to handling client funds. Law firm bookkeeping, therefore, often demands a higher degree of precision and a keen understanding of both financial and legal obligations. 

The Importance of Accurate Bookkeeping in Legal Practices

Accurate bookkeeping is the lifeline of any business, but in legal practices, its importance is magnified due to stringent ethical and legal obligations. Here’s a closer look at why precision in financial record-keeping is particularly critical for law firms:

Upholding Ethical Standards: The legal profession is bound by strict ethical guidelines, especially when handling client funds. Inaccurate bookkeeping can lead to co-mingling of firm and client funds, unintentional misuse of client money, or failure to promptly disburse funds when required. 

Financial Health of the Firm: Proper bookkeeping provides a clear snapshot of the firm’s financial health.

Streamlined Operations: Efficient bookkeeping means timely invoicing and faster payment cycles.

Regulatory Compliance: Law firms are often subject to various regulations, including tax obligations. Accurate bookkeeping ensures that the firm is compliant with all its financial reporting requirements and can avoid penalties, interest, or legal actions due to non-compliance.

Trust and Reputation: Clients trust law firms with their most sensitive issues. A firm that maintains accurate financial records and transparent transactions is likely to develop greater trust and confidence among its clientele. 

Risk Mitigation: Proper bookkeeping helps identify irregularities, potential fraud, or embezzlement. 

Understanding the Basics: Cash vs. Accrual Accounting

In managing a law firm’s money, it’s crucial to get how cash and accrual accounting work. Let’s take a look at these two key ways of tracking money to see which might be best for lawyers and their practices.

Cash-Based Accounting

Definition: In the cash-based accounting method, revenue and expenses are recorded only when cash changes hands. In other words, revenue is recognized when it’s received, and expenses are recognized when they’re paid.

Pros:  Cons
Simplicity: Easier to understand and maintain, especially for smaller firms.Doesn’t capture outstanding liabilities or receivables: It might not provide a comprehensive picture of the firm’s financial health.  
Direct cash flow reflection: It offers a clear view of how much cash the firm has at any given time.Less accepted for larger entities: Not always in line with Generally Accepted Accounting Principles (GAAP).

Accrual-Based Accounting

Definition: With accrual accounting, revenue and expenses are recorded when they are earned or incurred, regardless of when the cash is actually received or paid.

Pros:  Cons
Comprehensive: Provides a more accurate and holistic view of a firm’s financial health.  Complexity: Requires more meticulous bookkeeping and understanding of accounting principles
In line with GAAP: More widely accepted for larger firms and those with complex financial transactions.  Might not reflect cash on hand: Just because revenue is recognized doesn’t mean cash has been received
Key Components of Law Firm Financial Records

Key Components of Law Firm Financial Records

When managing a law firm’s finances, certain records are essential to keep everything running smoothly and compliantly. Here are the essential components:

General Ledger: The backbone of the firm’s financial records, the general ledger is a complete record of all financial transactions, categorized into various accounts.

Client Trust Accounts: Separate accounts for client funds that haven’t been earned yet. These need to be meticulously tracked to avoid any mixing with the firm’s funds.

Accounts Receivable: A record of all amounts owed to the firm by clients and other entities.

Accounts Payable: A record of all amounts the firm owes to vendors, service providers, and other entities.

Expense Records: Detailed records of all expenses incurred by the firm, categorized for easy tracking and analysis.

Billing and Invoice Records: Documentation of work done for clients, billable hours, fixed fee arrangements, and any other billing agreements.

Payroll Records: Detailed records of employee salaries, benefits, deductions, and other compensation-related information. Necessary for tax and regulatory compliance.

Bank Reconciliation Statements: Periodic checks to ensure that the firm’s bank account balances match the figures in the bookkeeping system.

Financial Statements: Periodic reports (like balance sheets, income statements, and cash flow statements) that provide a comprehensive overview of the firm’s financial health.

Tax Records: Documentation related to the firm’s tax obligations, payments, deductions, and any other relevant information.

Client Trust Accounts: Managing and Monitoring

Client trust accounts, often referred to as IOLTA (Interest on Lawyers’ Trust Accounts) in some jurisdictions, are essential instruments for law firms. These accounts hold client funds separately from the firm’s operational accounts to ensure there’s no co-mingling of client money with firm money.

Setting Up the Account

Segregation of Funds: Trust accounts must be separate from the firm’s operational accounts. Ensure that client funds are never deposited into the firm’s general account.

Interest-Bearing Accounts: In many jurisdictions, trust accounts must be interest-bearing, with the interest accrued used to support legal aid initiatives.

Bank Selection: Choose a bank familiar with trust account requirements to ensure compliance with local regulations.

Managing the Account

Deposits: Always obtain detailed deposit slips that clearly specify the client and matter related to each deposit.

Withdrawals: Withdrawals should only be made after earning the funds (i.e., after billing the client and performing the services). Always use checks or electronic transfers, avoiding cash withdrawals.

Third-Party Payments: In situations where the firm needs to pay third parties from the trust account on behalf of the client, ensure documentation of client authorization.

Monitoring and Reconciliation

Monthly Reconciliation: Match the bank statement with the trust ledger every month to identify discrepancies.

Client Sub-Ledgers: Maintain individual ledgers for each client to track their specific deposits and withdrawals.

Regular Audits: Periodically, conduct internal or external audits of the trust account to ensure everything is in order.

Ethical Considerations

Prompt Payment: If funds belong to the client (like settlements), they must be disbursed promptly.

Overdrafts: Never use one client’s funds to cover another client’s expenses.

Disputed Amounts: If there’s a dispute over a certain amount, it should remain in the trust account until the dispute is resolved.

Expense Tracking for Law Firms: What to Consider

Expense tracking is a vital activity for law firms, ensuring financial stability and compliance with legal accounting standards. When it comes to managing and recording expenses, law firms should consider the following elements to maintain an accurate and effective bookkeeping system:

Categorizing Expenses

Direct Costs: Costs related directly to client work, like court fees, expert witness fees, and deposition costs.

Operational Costs: General costs of running the firm, including rent, utilities, software subscriptions, and salaries.

Marketing and Business Development: Costs related to advertising, seminars, client entertainment, and other promotional activities.

Expense Allocation

Client-Billable Expenses: Direct costs that will be billed to the client. Ensure these are accurately tracked and itemized on invoices.

Firm-Borne Expenses: Costs the firm absorbs as part of doing business. While not billable, tracking these helps in budgeting and financial planning.

Documenting and Approving Expenses

Receipts: Always collect and store receipts for expenses. Digital storage solutions can help manage and retrieve them easily.

Approval Process: Implement an approval process for larger expenses to ensure they’re necessary and aligned with the firm’s goals.

Expense Reporting: Use software or manual logs to regularly report and review expenses.

Budgeting and Analysis

Annual Budgeting: Based on past expenses, set a budget for the upcoming year, considering potential changes like expansion or increased marketing efforts.

Regular Review: Periodically review expenses against the budget to ensure the firm stays on track. Analyze any significant overruns or under-spends.

Expense Ratios: Compare expenses to revenues to understand the firm’s profitability and make necessary adjustments.

Recording Billable Hours and Invoice Management

Recording billable hours accurately and managing invoices efficiently are critical to the financial success and credibility of a law firm. Here’s a systematic approach to ensure these processes are handled effectively:

Recording Billable Hours

Time Tracking Tools: Implement user-friendly time tracking software or apps that allow attorneys and staff to log hours in real-time.

Standardized Time Increments: Establish whether the firm will bill in six-minute increments (common in the industry) or another interval.

Descriptive Entries: When logging hours, ensure descriptions are clear and detailed enough for clients to understand the work done but without revealing confidential information.

Non-Billable Hours: Track non-billable hours (administrative tasks, internal meetings, etc.) as well to understand productivity and firm efficiency.

Regular Time Entry: Encourage attorneys and staff to record hours daily or at least weekly to ensure accuracy and reduce the likelihood of forgetting tasks.

Invoice Management

Invoice Generation: Use accounting or practice management software to generate invoices based on logged billable hours and fixed fees.

Itemized Breakdown: Ensure invoices provide an itemized list of services rendered, along with respective costs and total hours worked.

Disbursements & Expenses: Include any client-billable disbursements or expenses, ensuring they’re clearly differentiated from hourly charges.

Payment Terms: Clearly indicate payment terms (e.g., due upon receipt, net 30 days) and any late payment penalties.

Electronic Invoicing: Consider offering electronic invoicing for convenience and quicker payments. Include various payment options for clients.

Invoice Tracking: Monitor unpaid invoices, sending reminders as needed, and consider implementing an automated system for follow-ups.

Allocating Income: Partners, Associates, and Overheads Partners

Allocating income within a law firm isn’t just about numbers and percentages; it’s about recognizing the hard work and dedication of every individual who contributes to the firm’s success. From the seasoned partners to the diligent associates whose efforts keep the gears turning, and the support staff who ensure the day-to-day operations run smoothly – each plays a pivotal role.

 Here’s how a law firm can thoughtfully and fairly distribute income, ensuring that everyone’s contribution is valued and the firm’s foundations remain strong.

Equity Partners: Their income is typically derived from the firm’s profits. 

Salary Plus Bonus: Some partners may receive a fixed salary plus a bonus based on performance, origination, or other criteria.

Capital Contributions: Consider any capital a partner has injected into the firm, which might affect their income distribution.


Fixed Salary: Most associates receive a fixed annual salary, which might be tiered based on years of experience or expertise.

Performance Bonuses: Bonuses can be awarded based on billable hours, business generation, client feedback, or other performance indicators.


Regular Expenses: Deduct regular operational expenses such as rent, utilities, salaries of non-legal staff, and general office expenses.

One-off Expenses: Account for irregular or one-time expenses such as new equipment purchases, office renovations, or settlements in legal disputes.

Reserves: Allocate a portion of income to reserves for future expenses, potential downturns, or expansion plans.

Distribution Timing

Frequency: Decide on the frequency of income distribution – monthly, quarterly, semi-annually, or annually.

Holding Periods: Consider any holding periods for income to ensure the firm maintains adequate liquidity for operational needs.

Transparency & Communication

Open Books: Consider an open-book policy where partners (and possibly senior associates) can view the firm’s financials to understand income allocation.

Regular Financial Meetings: Hold regular meetings to discuss the firm’s financial status, upcoming expenses, and income allocation decisions.

The Role of Legal Accounting Software

Modern law firms depend on legal accounting software to guide their financial journey. This technology isn’t merely a tool; it becomes a member of the team, working around the clock, safeguarding the firm’s financial integrity, and shining a light on the path to fiscal responsibility

Streamlining Financial Processes

Automation: Legal accounting software often automates routine tasks like invoice generation, expense tracking, and financial report compilation, saving time and reducing manual errors.

Integration with Time Tracking: Most legal-specific accounting software integrates seamlessly with time tracking tools, ensuring accurate billing.

Trust Account Management

Ethical Compliance: Given the sensitivity of client trust accounts, specialized software ensures ethical rules are adhered to, helping prevent unintentional co-mingling of funds.

Automated Reconciliation: Software can simplify the monthly reconciliation process, matching transactions with bank statements and highlighting discrepancies.

Detailed Reporting

Financial Overviews: Generate comprehensive financial reports, like profit and loss statements or balance sheets, with just a few clicks.

Client-Specific Reports: Obtain detailed financial histories for individual clients, useful for understanding client relationships and payment behaviors.

Secure Data Storage

Cloud-based Solutions: Many legal accounting software options are cloud-based, allowing for secure data storage, regular backups, and remote access.

Encryption: Client data and financial transactions are encrypted, ensuring protection from potential breaches.


Growth Support: As a law firm grows, so do its accounting needs. Legal accounting software can scale to support multiple users, larger volumes of data, and complex financial operations.

Understanding Tax Obligations for Law Firms

Business Structure Implications

Sole Proprietorship: Income and expenses are typically reported on the individual’s tax return. The owner pays personal income tax on the firm’s profits.

Partnerships: Profits and losses flow through to the individual partners, who report them on their personal tax returns. Each partner’s share is determined by the partnership agreement.

Corporations: The firm may be taxed at the corporate rate, and shareholders (often attorneys) pay individual taxes on dividends or salaries received.

Deductible Expenses

Ordinary and Necessary: Only expenses that are both ordinary (common in the legal profession) and necessary (helpful for the business) are deductible.

Examples: Office rent, utilities, salaries, continuing legal education, bar dues, and legal subscriptions are generally deductible.

Employment Taxes

Payroll Taxes: If the firm has employees, it’s responsible for withholding federal income tax and FICA (Social Security and Medicare) taxes from their wages.

Self-Employment Taxes: Sole proprietors and partners in a partnership must pay self-employment taxes, which cover Social Security and Medicare.

Quarterly Estimated Payments

For Self-Employed Attorneys: If the firm doesn’t withhold taxes for you (common for partners and solo practitioners), you’ll likely need to make quarterly estimated tax payments to the IRS.

Penalties: Failing to make sufficient estimated payments can result in penalties, even if you pay the full amount owed by the tax filing deadline.


Maintain Comprehensive Records: Keep detailed records of income, expenses, and deductions to make tax preparation easier and ensure compliance.

Retention: Tax records should be retained for a minimum period specified by tax authorities (often 3-7 years), as they may be required in the event of an audit.
