Why Year-End Planning Matters for Law Firms

Once the calendar turns, many of the decisions that shape your firm’s tax bill, partner compensation, and cash position for the entire year are locked in. Yet year-end often arrives in a rush of billing pushes, holiday schedules, and client deadlines. Firms that start planning in October or November give themselves room to make deliberate choices. Here are some areas to review and make sure you have a plan for your firm.

Required Payroll: Payroll is where year-end deadlines are least forgiving. Wages are generally taxed and reported in the year they are actually paid, so a bonus paid on January 2 belongs to next year, no matter when it was earned.

• Bonuses for associates and staff: Decide bonus amounts early and confirm your payroll provider’s final processing date, which often falls a week or more before 12/31.
• Retirement plan deferrals: Employee 401(k) deferrals must come out of paychecks dated in the plan year. Partners and shareholders who want to max out need their final elections processed before the last payroll runs. Employer profit-sharing and cash balance contributions often have later deadlines, but make sure to check your plan details.
• Fringe benefits and reimbursements: Personal use of firm vehicles, health insurance for 2% + S corporation shareholders, and any taxable fringe benefits must be added to W-2 wages. Collect outstanding expense reports so accountable-plan reimbursements are processed in the right year.
• Contractor and W-2 prep: Verify addresses and Social Security numbers now to avoid January scrambles. Collect W-9s from contract attorneys, experts and vendors ahead of 1099 filing, which is due January 31.

Tax Planning: Timing Is Everything

Most law firms report on the cash basis, which makes year-end timing a powerful lever. Income counts when it is collected, and expenses count when they are paid. Make sure to check in with your CPA before proceeding with any of the bullet points below.

• Manage receivables deliberately: A strong December collections push increases this year’s income. That is usually good for cash flow, but it’s worth projecting the tax impact first, especially if next year is expected to be slower or rates are changing.
• Accelerate deductible expenses: Do you pay your 1099s for work done in December in January? If you are on cash basis accounting, you may consider prepaying partial December work before the year ends. Check the prepaid-expense rules with your CPA.
• Time equipment and technology purchases: Computers, furniture and practice-management systems placed in service by 12/31 may qualify for Section 179 expense or bonus depreciation.
• Consider a pass-through entity tax (PTET) election: Many states let partnerships and S corporations pay state income tax at the entity level. This can work around the federal cap on individual state and local tax deductions, but elections and payments often carry year-end deadlines.
• Run a projection before you act: Every one of these moves should start with a current-year tax projection for the firm and each owner.

Structure: Is Your Firm Set Up for Next Year?

Year-end is the natural checkpoint for asking whether your firm’s structure still fits how it operates. Many structural changes take effect on January 1, so decisions need to be made before then.

• Entity and tax classification: A solo practitioner may now benefit from a different business structure. A growing firm may be outgrowing its current setup entirely. The right answer depends on a multitude of questions that are worth exploring.
• Partner and shareholder compensation: Review how profits are allocated, how guaranteed payments are set, and whether draws match expected income. Mismatches discovered in April are much harder to fix than those caught in December.
• Operating and partnership agreements: Admitting a new partner, a retirement, or a change in profit-sharing formulas usually requires an updated agreement. Getting it signed before year-end keeps allocations clean from the first day of the new year.
• Retirement plan design: Reviewing your current plan, or exploring new plans may be the right move for your firm. New plans may need to be adopted before 12/31 to count for the current year.

The best year-end outcomes come from firms that treat the fourth quarter as a planning season rather than a deadline. Starting in October or November gives you time to run projections, compare options and act before payroll cutoffs close the door.

Every firm’s situation is different, and tax rules change often. Work with advisors who understand your law firm finances to build a year-end plan that fits your practice.
