FAQ: Questions attorneys often ask
Q1. Do I really need a separate bookkeeper if I’m a solo attorney?
Many solo attorneys start out managing their own books, but as billable work grows, bookkeeping often falls behind or becomes inaccurate. When your books are not up to date, you risk missing deductions, misclassifying retainers, and scrambling at tax time. Outsourcing bookkeeping to a firm that understands law practices gives you cleaner records, better tax outcomes, and more time for client work.
Q2. How should my law firm handle trust/IOLTA accounting from an accounting perspective?
Trust accounts must be tracked separately from your operating funds, and every client’s trust balance should be reconciled regularly. A proper system uses matter-level tracking, three-way reconciliations, and clear documentation for every disbursement and transfer. Working with a bookkeeping team familiar with legal trust accounting helps you stay compliant with bar rules and avoid serious disciplinary risk.
Q4. Should I operate as an LLC, S‑corp, or something else for my law practice?
There is no one-size-fits-all answer; the best entity type depends on your income, number of owners, risk profile, and long-term plans. Our accountants can perform cost-benefit analysis to determine the right tax entity structure for your firm.
Q5. How can I estimate quarterly taxes as a law firm owner with uneven income?
Our tax pros project your annual profit based on year-to-date results and planned work, then calculate safe‑harbor estimates for federal and Maryland taxes. Adjusting estimates mid-year as your pipeline changes can reduce penalties while preventing overpayments that strain your cash flow.
Q6. What should I do if my books are behind and tax season is coming up?
If your books are months behind, don’t panic—and don’t ignore it. Our team can provide add-on back-up bookkeeping services, if needed.
