Year-End Financial Planning for Business Owners: A Checklist

A September-to-December planning timeline

Year-end financial planning for business owners tends to work best as a series of short steps rather than a December scramble. In September and October, many owners gather year-to-date financial statements and list the decisions still open. In November, that list can go to your CPA and, where relevant, your attorney. In December, any decisions that remain have time to be made deliberately.

The checklist below is a set of questions, not a set of recommendations. Some will not apply to your business, and the right answer to any of them depends on facts that only you and your outside professionals can see.

Cash flow and estimated-tax questions to raise before December 31

Start with a current picture of the business: year-to-date revenue and expenses, large invoices still outstanding, and purchases or payroll items expected before the year ends. Then compare that picture with what you assumed earlier in the year. Income that came in higher or lower than expected can change the conversation with your CPA.

Individuals with income that is not subject to withholding, which can include some business owners, may be required to make quarterly estimated tax payments. For tax year 2026, the IRS lists the fourth payment, covering September 1 through December 31, as due January 15, 2027 (IRS Publication 505, as of November 7, 2026). Whether you owe estimated payments, and in what amount, is a question for your CPA.

Useful questions to bring: Has income this year run ahead of or behind plan? Is there enough cash set aside for the next payment date? Are there large one-time items, such as an equipment purchase or a bonus, that could change the picture?

Retirement plan contribution decisions to review

If your business sponsors a retirement plan, or you are considering one, year-end is a natural time to ask what contributions you have made so far and what remains open. For 2026, the IRS limit on employee elective deferrals to a 401(k) plan is $24,500, with separate catch-up rules for older participants (IRS announcement, as of November 7, 2026). Other plan types have different limits and rules.

Contribution deadlines, payroll timing, and when a plan can be adopted or amended differ by plan type and by plan document, so confirm the dates that apply with your plan provider and CPA. A planning question to add: how would a larger contribution affect your business cash flow and personal liquidity? Contributions are a trade-off, and they may not suit every owner or every year.

Business records and entity-level questions

Clean records make every other conversation easier. Many owners use the fall to reconcile accounts, confirm how owner pay and distributions were handled during the year, and make sure documentation is current for your CPA.

Entity-level questions, such as whether your current business structure still fits how the business operates, or whether ownership agreements reflect today's circumstances, belong with your CPA and attorney. An advisor can help organize the financial side of those questions, but does not provide tax or legal advice.

Liquidity needs to map before the year ends

Business owners often hold much of their net worth in the business, so it can help to map where cash will come from over the next 12 months. Consider upcoming tax payments, loan payments, capital purchases, payroll cycles, and personal spending needs, and note which are fixed and which are flexible.

Holding more cash improves flexibility but may mean giving up other uses for those funds, and there is no single right reserve level. The goal of the exercise is to see the trade-offs clearly before a decision is made.

Next-year planning priorities

Year-end is also a practical moment to write down what you want the next 12 months to look like: growth plans, hiring, major purchases, owner compensation, and personal goals such as retirement timing. Ranking these helps you see which ones need cash, which need professional input, and which can wait.

If a sale or transition is part of your longer-term thinking, keeping a working estimate of what the business is worth can inform those priorities. Our guide to what your business is worth explains how a planning valuation differs from a formal appraisal.

Where your CPA and attorney fit

Your CPA prepares your returns and advises on how tax law applies to your situation, including estimated payments and entity questions. Your attorney handles legal documents such as operating agreements, buy-sell agreements, and ownership changes. Neither role is replaced by financial planning.

A planning advisor can, with your permission, help organize the financial picture and share it with your outside professionals so everyone works from the same information. Boston Integrity coordinates with your CPA and attorney and does not prepare tax returns or provide tax or legal advice.
