Staying Ahead of Tax and Regulatory Changes: What Your Bookkeeper Wishes You'd Tell Them Sooner

Tax and entity rules for law firms rarely stay still for long, and right now, with future changes still uncertain, that's truer than usual. But one of the biggest risks to a firm's compliance isn't a change in the law itself. It's a change happening inside the firm that nobody tells the bookkeeper about.

Here's what attorneys should understand about staying ahead of these changes, and why the accounting firm managing your books needs to be part of the conversation, not brought in after the fact.

Entity Changes Need to Be a Group Conversation

Many law firms start as LLCs and eventually cross the bridge to an S corp election. That transition brings real requirements: a reasonable salary, proper payroll setup, correctly structured shareholder distributions, and decisions about retirement plans and benefits that all need to work together.

The problem isn't usually the decision to make the switch. It's that the firm's bookkeeping team often finds out well after the fact, sometimes months later, after distributions have continued flowing with no payroll ever set up behind them. At that point, there's catch-up work to do that could have been avoided entirely with an earlier conversation.

If your firm is considering (or has already made) a change in entity structure, looping in your bookkeeping or accounting firm at the time of the decision, not after, makes the difference between a smooth transition and a cleanup project.

Reasonable Salary Isn't a Guess

If you've elected S corp status, "reasonable compensation" isn't just a phrase, it's a requirement with real consequences if it's ignored. A salary that's too low relative to shareholder distributions creates exactly the kind of red flag that draws scrutiny: a token salary paired with distributions many times larger doesn't hold up, and unwinding it after the fact means reclassifying everything.

Determining what's reasonable takes into account the actual work being done, industry benchmarks, and the specific structure of the business, which is exactly why this is a conversation to have directly with a tax professional rather than a number to pull out of thin air. A good accounting firm can help facilitate that conversation and make sure the bookkeeping reflects it accurately, but the underlying determination belongs with your CPA or tax advisor.

Where the Line Sits Between Bookkeeping and Tax Advice

A recurring theme worth naming directly: bookkeepers and accountants are not tax advisors, and a good one will tell you that clearly. Your bookkeeping team doesn't have the full picture of your personal finances, your broader tax situation, or the nuances that only a CPA or tax preparer who prepares your return will have visibility into.

What a strong bookkeeping partner can do is flag when something looks worth a conversation. That might mean noticing a client hasn't set up estimated quarterly tax payments, seeing a 401(k) plan that may be out of balance with employee contributions, or recognizing when profit sharing needs to be coordinated before a deadline. None of that is tax advice. It's facilitation, built on being close to the numbers all year long in a way a tax preparer, who may only see the full picture once a year, often isn't.

Advanced Client Costs: A Small Decision With Big Ripple Effects

One specific area worth understanding is how client-advanced costs, expenses a law firm pays on a client's behalf before being reimbursed, get treated on the books. There are two common approaches: booking them as an expense on the profit and loss statement, or booking them as a cost receivable on the balance sheet.

The distinction matters more than it might seem. If costs are expensed as they're paid and then the related reimbursement or settlement is recognized as income in a later year, the two never offset properly within the same period. That can inflate expenses in one year and inflate income in another, muddying the real financial picture of the firm and making tax planning much harder. Treating advanced costs as a receivable, essentially a loan to the client, keeps the picture cleaner and ties reimbursements back to the specific costs that generated them.

There's no single universally "right" answer here, and different tax professionals may have different preferred methods. What matters is that the method is chosen deliberately, applied consistently, and understood by both the firm and whoever is preparing the tax return, rather than being left over from decades-old habits nobody remembers the reasoning behind.

Cash Flow Deserves Its Own Conversation

For practice areas like personal injury, where a firm may front significant costs long before a case resolves, cash flow planning is its own challenge. Some firms choose to bill advanced costs as they're incurred rather than waiting for a case to close, which can ease that cash flow pressure considerably. Whatever approach a firm takes, tracking a growing balance of unbilled costs is worth paying attention to, since it can be an early signal that billing isn't keeping pace with the expenses being incurred.

The Bottom Line

None of this replaces a relationship with a qualified tax professional, and any accounting firm worth working with will say so plainly. But the firms that navigate entity changes, compensation questions, and cost tracking most smoothly tend to be the ones where the bookkeeping team, the tax preparer, and the attorney are all working from the same information, in real time, rather than finding out about major changes after the fact.

If there's one habit worth building into your firm's routine, it's this: whenever something changes, an entity election, a new retirement plan, a shift in how costs are billed, tell your bookkeeping team when it happens, not months later. It costs nothing, and it's often the difference between a clean transition and a cleanup project.

At The Proper Trust, staying close to these details all year is exactly the kind of ongoing partnership we aim to provide, so that when it's time to talk to your tax professional, the numbers are ready and the story they tell is clear.
