Why year-end planning still matters
Most business owners already feel stretched in the final quarter: customer demands spike, inventory moves, and finance work competes with everything else on the calendar. Even so, a focused pass on tax and compensation items before December 31 often pays for itself—either in lower tax or in fewer clean-up hours your CPA bills later.
This article is written for leaders who are not trying to optimize every edge case, but who want a sensible, low-regret checklist they can run with their accountant or internal finance lead.
Step 1: Reconcile estimated payments and cash-tax expectations
If you pay quarterly estimates personally or through the business, compare YTD payments to a current-year projection. A mid-November or early December check leaves time for a Q4 true-up without scrambling.
Gather YTD federal and state withholding or estimates.
Update the annual income forecast with your latest P&L and known one-off items.
Flag any large timing differences—bonus accruals, asset sales, or debt forgiveness—and discuss them with your advisor.
Step 2: Entity structure and owner compensation
Owners often revisit whether current salary or guaranteed payments still match reasonable compensation norms for the business size and profitability. This is especially relevant for S corporations, where wage schedules influence payroll tax.
Year-end is rarely the moment to casually restructure—but it is the right time to confirm that payroll, distributions, and partnership allocations reflect what you intended all year.
If you are considering an election or ownership change effective January 1, paperwork and elections typically need to be drafted before the holidays, not during them.
Step 3: Retirement and deferred compensation
Plans such as 401(k), SEP-IRA, or defined-contribution setups often have funding deadlines tied to the tax year or the extended return due date. Confirm:
Whether you have room left under annual contribution limits.
Whether employee deferrals were deposited on time during the year (a common audit focus).
Whether a profit-sharing or employer contribution fits cash flow once bonuses are modeled.
Step 4: Accelerate—or defer—only with a written rationale
Accelerating deductible expenses or deferring income can make sense when tax brackets are stable and you have clear visibility into next year. It becomes risky when revenue is lumpy or you expect a material change in entity type.
Document the decision in an email or short memo: what you did, why, and who approved it. That discipline saves hours when something looks odd on a return six months later.
Step 5: Related-party and intercompany transactions
Loans between you and the business, leases of personal assets, or charges between entities should have supporting agreements and market-ish terms. If you have been informal all year, year-end is a good moment to assemble a one-page summary your preparer can attach to the workpapers.
Before you sign off
Ask for a short close checklist from finance: bank reconciliations, fixed-asset schedules, loan statements, and inventory counts if applicable. The tax return is only as reliable as the books beneath it—closing the year with discipline carries straight into a smoother audit or financing process in the spring.
