Q4 Readiness: Five Priorities for Tax Leaders Before Year-End
For calendar-year tax teams, October brings two competing demands: finishing the current year well and making decisions that will shape the next one. Provision work, remaining compliance obligations, planning projects, and budget conversations can quickly fill the same calendar.
The start of Q4 is a useful point to assess where the work stands, what could complicate the close, and whether the team has the capacity to deliver. These five priorities can help tax leaders make that assessment more concrete.
1. Bring unresolved issues into the year-end plan
Start with the items that could require additional analysis, review, or coordination before the annual provision is complete. Depending on the business, these may include valuation allowances, uncertain tax positions, deferred tax balances, transaction-related matters, or changes in state and international exposure.
Identify what remains open, who owns each issue, and which decisions or data requests depend on other teams. Agree on review dates with accounting, finance, and external advisers so those dependencies are visible before the close schedule tightens.
A year-end plan should account for the difficult work as well as the recurring work. An unresolved issue without an owner or a review date deserves attention now.
2. Confirm that tax changes are reflected in the work
The 2025 federal tax legislation changed several business tax provisions, and the IRS has issued guidance addressing areas including bonus depreciation and business interest deductions. Tax teams should confirm which changes and effective dates apply to their organizations as they prepare year-end calculations and next year's forecasts.
That review should extend beyond the technical conclusion. Have the relevant models been updated? Is the supporting data available? Do workpapers and review procedures reflect the applicable rules? Has finance been briefed on potential effects on the tax forecast?
Assign responsibility for monitoring guidance and documenting its implications. Where an issue remains unresolved, make the next step and the decision owner clear.
3. Connect tax planning to the business forecast
Q4 planning is more useful when tax has a current view of the business. Changes in profitability, capital spending, financing, acquisitions, or the geographic mix of earnings may affect assumptions used earlier in the year.
Meet with the relevant finance and business leaders to understand what has changed and what is still expected before year-end. Use those conversations to reassess projected cash taxes, estimated payments, and planning opportunities where appropriate.
This also gives tax leaders an opportunity to explain which business decisions require tax input before execution and what information the team needs to evaluate them.
4. Assess capacity by responsibility
A fully staffed department can still have significant coverage gaps. Review the responsibilities behind the headcount: who prepares the provision, who reviews international calculations, who manages adviser relationships, and who can step in when a key person is unavailable?
Look for work concentrated with one employee, review bottlenecks, and recurring demands that leave little time for planning or process improvement. Discuss those pressures with the people doing the work, including where additional training, clearer ownership, or outside support would help.
If a permanent hire is needed, define the expertise and responsibilities before launching a search. Build interview availability, notice periods, and onboarding into the plan, particularly when the person will be expected to contribute during the close.
5. Make the next-year budget case specific
Use Q4 budget discussions to connect resource requests to identifiable work. A request for another tax professional is easier to evaluate when it explains the responsibilities that need coverage, the skills required, and the effect on the existing team.
Apply the same discipline to technology and advisory spending. Identify the process a tool would improve, the work an adviser would support, and the internal time required to implement either successfully.
Before finalizing the plan, agree with finance leadership on priorities and tradeoffs. If every project cannot be funded, the tax team needs clarity on what will proceed and what will be deferred.
The decisions made in Q4 influence both the year-end close and the team's ability to support the business in the year ahead. Taking time now to resolve ownership, assess capacity, and define resource needs gives tax leaders a stronger foundation for both.
