Bookkeeping for a Solo or Small Law Firm in Texas (Case Costs, Time Billing, IOLTA Separation, and Monthly Close)

Disclaimer: The information on this website (including all examples, explanations, and content) is for general informational purposes only and should not be considered tax, legal, or financial advice. IOLTA trust account matters are governed by the Texas Disciplinary Rules of Professional Conduct and the State Bar of Texas.

Law Firm Bookkeeping Has Two Specific Items Most Other Small Businesses Do Not

The two items that distinguish law firm bookkeeping from generic small business bookkeeping are case cost advances (the firm pays expert fees, court costs, deposition costs on behalf of clients and gets reimbursed later) and the IOLTA trust account (the firm holds client funds in trust, completely separate from operating funds).

The case cost piece is a regular bookkeeping topic that has to be handled correctly. The IOLTA piece is a regulatory topic that has to be handled correctly to avoid State Bar disciplinary issues. They live in the same firm but they live in different worlds, and they should not be confused.

This post walks through the practical bookkeeping setup for a Texas solo attorney or small law firm. IOLTA accounting is mentioned only to note where it sits in the structure; specific IOLTA guidance belongs with the State Bar of Texas, not this post.

Chart of Accounts for a Small Law Firm

Revenue Accounts

  • Hourly Fee Revenue (or split by practice area)
  • Flat Fee Revenue
  • Contingency Fee Revenue
  • Retainer Revenue (recognized as earned, not when retainer is deposited)
  • Referral Fee Income (if applicable)

Cost of Service Accounts

Law firms generally do not have COGS in the traditional sense. There are no inventory items being sold. Costs are operating expenses rather than cost of services.

Operating Expense Accounts

  • Wages and Payroll Taxes
  • Employee Benefits
  • Rent
  • Utilities
  • Phone and Internet
  • Practice Management Software (Clio, MyCase, PracticePanther, Smokeball, Filevine)
  • Legal Research Subscriptions (Westlaw, LexisNexis, Casetext, Fastcase)
  • Document Management and E-signature Tools
  • Marketing and Advertising
  • Continuing Legal Education
  • Professional Memberships (State Bar of Texas, local bar associations, sections)
  • Malpractice Insurance (E&O)
  • General Liability Insurance
  • Office Supplies
  • Repairs and Maintenance
  • Depreciation Expense
  • Bar Dues and Licensing Fees
  • Federal Court Admission Fees

Balance Sheet Accounts

  • Operating Cash Account (firm operating funds)
  • IOLTA Trust Account (segregated client funds; covered by State Bar rules)
  • Reserve / Savings Account
  • Accounts Receivable
  • Case Cost Receivable (advanced case costs awaiting client reimbursement)
  • Unearned Retainer (deferred revenue from advance fee deposits not yet earned)
  • Fixed Assets (Office Equipment, Furniture, Computers)
  • Accumulated Depreciation
  • Accounts Payable
  • Credit Cards Payable
  • Loans Payable
  • Owner Equity

The IOLTA account is on the balance sheet but it is fundamentally a held in trust item. Client funds in IOLTA are not firm assets. Withdrawals from IOLTA happen only as fees are earned (and then move to operating) or as case costs are paid on behalf of the client. The IOLTA balance must match the sum of individual client subaccount ledgers at all times.

Case Cost Advances: Gross Method vs Net Method

This is the most distinctive bookkeeping topic for a law firm. There are two acceptable methods.

Gross Method

Under the gross method:

  • Case cost advanced to client posts to Case Cost Receivable (balance sheet asset)
  • Client reimbursement posts as a reduction of Case Cost Receivable (not as revenue)
  • The case cost is not deducted as a firm expense

This method is required for personal injury contingency firms in many jurisdictions and is generally favored when case cost advances are large.

Net Method

Under the net method:

  • Case cost advanced posts to a Case Cost Expense account (P&L)
  • Client reimbursement posts as a Case Cost Reimbursement income account (or as a reduction of the expense)
  • Net result on P&L is zero if reimbursements equal advances

This method is simpler in the bookkeeping but produces a P&L where the case cost activity is visible (both expense and reimbursement lines) rather than living entirely on the balance sheet.

Which to Use

Talk to your tax advisor about which method is right for your firm. The choice depends on:

  • Firm's practice area mix (contingency vs hourly)
  • Total case cost advance volume
  • Audit and tax method considerations

Once you choose a method, stay consistent. Switching methods requires Form 3115 and IRS approval.

IOLTA Trust Account: Separate, Always

The IOLTA trust account holds client funds and is completely separate from firm operating funds. The bookkeeping for IOLTA is its own discipline.

Key Principles

  • Every client whose funds are in IOLTA has a subaccount ledger
  • The sum of subaccount ledgers must equal the IOLTA bank balance at all times (the "three way reconciliation")
  • Funds never move from IOLTA to operating except as fees are earned
  • Operating funds never go into IOLTA
  • The IOLTA account is reconciled monthly

The State Bar of Texas has specific rules and a Trust Account Handbook. Any IOLTA accounting question belongs there, not in a general bookkeeping post.

What This Post Does Not Cover

Specific IOLTA accounting practices, three way reconciliation procedures, handling of disputed funds, escheatment of unclaimed client funds, and any other IOLTA specific topic. The State Bar of Texas and the firm's malpractice carrier are the authorities on these. Get the specifics from them.

Time and Billing Integration

Most law firms use practice management software that handles time entry, billing, and trust accounting. The integration with general ledger bookkeeping (QuickBooks or similar) typically happens through a monthly summary entry rather than transaction by transaction sync.

The summary entry captures:

  • Fees earned for the month (revenue)
  • Trust deposits and withdrawals
  • Case costs advanced and reimbursed
  • Payments received from clients

The bookkeeper reconciles the practice management software balances to the books each month. If the two do not match, the firm has a reconciliation problem to solve.

Equipment and Office Asset Depreciation

Computers, monitors, office furniture, and printers are tracked as fixed assets and depreciated. Section 179 and bonus depreciation can accelerate the deduction. Our Section 179 vs bonus depreciation post covers the tax side.

The Monthly Close

A good monthly close for a small law firm produces:

  • Reconciled operating bank account
  • Reconciled IOLTA trust account (three way reconciliation, internal to the State Bar rules)
  • A/R reconciled to practice management aging
  • Case cost receivable reconciled to case cost ledger
  • Unearned retainers reconciled to client retainer balances
  • Owner compensation recorded correctly
  • Loan principal and interest split correctly
  • Depreciation entries
  • Reviewed P&L and balance sheet

Common Small Law Firm Bookkeeping Mistakes

Mixing IOLTA and Operating Funds

The single most serious mistake. Mixing client trust funds with firm operating funds is a bar disciplinary issue, not just a bookkeeping issue. Keep them completely separate.

Treating Retainers as Revenue When Received

Retainers are deferred revenue (or specifically, advance fees that may or may not be deposited in trust depending on the retainer structure). They are recognized as revenue as services are performed, not when the cash arrives.

Inconsistent Case Cost Method

Switching between gross and net methods or applying them inconsistently produces books that do not reconcile. Pick a method and stay with it.

Not Reconciling IOLTA Monthly

State Bar rules require regular reconciliation. The three way reconciliation (bank statement, internal ledger, subaccount ledgers) is mandatory.

Mixing Personal and Firm Expenses

Owner personal expenses through the firm card create messy books.

Skipping the Monthly Close

Law firm books require active monthly attention because of trust accounting requirements.

Frequently Asked Questions

Should my retainer go into IOLTA or operating?

Depends on the retainer structure. True retainers (earned upon receipt) generally go to operating. Advance fee deposits (held until earned) generally go to IOLTA. The State Bar of Texas rules govern. Get the specific answer from the State Bar, not from a general bookkeeping post.

Cash basis or accrual basis?

Most small law firms can use either method. Cash basis is simpler but does not show A/R and case cost advances on the books. Accrual basis shows the full picture but adds complexity.

Do I need separate accounts for each client?

For IOLTA purposes, yes, you need subaccount ledgers per client matter. For operating purposes, the level of detail is the firm's choice.

Should I use Clio or QuickBooks?

Most firms use both. Clio (or similar practice management software) handles time, billing, and trust accounting. QuickBooks (or similar general ledger software) handles the firm's general bookkeeping. The two reconcile through a monthly entry.

Should I outsource bookkeeping?

Most small law firms benefit from outsourcing to a bookkeeper familiar with law firm bookkeeping. The case cost methods, the IOLTA separation, and the time and billing reconciliation are easier with someone who knows the patterns. For IOLTA specifically, work with a bookkeeper who has experience with trust accounting and check in with the State Bar resources directly.

What if my IOLTA does not reconcile?

Stop. Do not move forward until it is fixed. Notify your malpractice carrier and consider whether to contact the State Bar's ethics helpline. IOLTA imbalances can be disciplinary matters and they get worse if ignored.

Getting Small Law Firm Bookkeeping Right

Law firm bookkeeping has more compliance burden than most small businesses because of IOLTA, but the underlying mechanics are otherwise straightforward. The firms that handle it well have a clear case cost method, monthly IOLTA reconciliation, consistent retainer accounting, and practice management software reconciled to the general ledger each month.

The IOLTA piece in particular deserves specialist attention. A general bookkeeper is not enough. A bookkeeper who has worked with law firms on trust accounting and who keeps current on State Bar of Texas rules is what most firms need.
