1. Review Your S Corp Salary
If you work for your S Corporation, one of the first things to review is how much the company has paid you through payroll. S Corp shareholder-employees generally need to receive reasonable compensation for the services they provide before taking non-wage distributions. What qualifies as reasonable compensation depends on factors such as your responsibilities, experience, time spent working in the business, industry, and what similar businesses pay for comparable work. If most of the money you took from the company was classified as distributions while very little went through payroll, this deserves attention before year-end. For a deeper explanation, read our guide on how to pay yourself as a business owner.2. Compare Salary and Shareholder Distributions
Salary and distributions are treated differently for tax purposes, which is one reason many business owners choose an S Corp structure. However, an S Corp should not simply replace reasonable wages with distributions to avoid payroll taxes. Review your year-to-date payroll alongside the distributions you have received and make sure they reflect how you actually work in the business. If your business has grown significantly this year or your responsibilities have changed, compensation that made sense last year may no longer be appropriate. If you are still learning how this business structure works, see our article on S Corp tax benefits for small business owners.3. Make Sure Payroll Is Up to Date
Payroll problems are much easier to address before the year closes than during tax preparation. Review your payroll records and confirm that wages, payroll tax deposits, employee information, and shareholder compensation have been recorded correctly. If you use a payroll provider, compare its reports with your bookkeeping records. Pay particular attention to any bonuses, additional owner compensation, or payroll adjustments you expect to make before December 31.4. Review Your Profit and Loss Statement
Your profit and loss statement gives you a clearer picture of how the business performed during the year. Look at revenue, payroll, contractor payments, rent, advertising, insurance, professional fees, vehicle expenses, software, equipment, and other major categories. Compare the numbers with the prior year and investigate anything that looks unusually high, low, or incorrectly categorized. Accurate books are important because tax planning based on incomplete financial information can lead to poor decisions.5. Look for Legitimate Business Expenses That Have Not Been Recorded
Business owners sometimes pay legitimate company expenses personally and forget to enter them into the accounting system. Review business-related purchases such as software subscriptions, professional services, business travel, supplies, insurance, education, advertising, equipment, and other ordinary expenses associated with operating your company. The goal is not to spend money simply to create a deduction. Instead, make sure legitimate expenses that already belong to the business are properly documented and recorded.6. Review Equipment and Major Purchases
If your company purchased computers, machinery, vehicles, furniture, tools, or other business equipment during the year, discuss how those purchases should be treated for tax purposes. Depending on the asset and your circumstances, depreciation rules may affect when and how much of the cost can be deducted. If you were already planning a necessary business purchase, year-end can be a good time to discuss its timing with your tax professional. Avoid buying something solely for a potential deduction without considering its effect on cash flow and the business itself.7. Review Retirement Plan Opportunities
Retirement planning can be an important part of an S Corp owner’s overall tax strategy. Depending on the company and its employees, options may include a 401(k), SEP IRA, SIMPLE IRA, or another qualified retirement plan. Each option has different eligibility requirements, contribution rules, deadlines, and administrative responsibilities. Some decisions may need to be made before year-end, so this is an area that should not automatically be left until tax filing season.8. Check Estimated Tax Payments
Even when your S Corp runs payroll and withholds taxes from your salary, you may still need estimated tax payments depending on your total income and tax situation. S Corporation income generally passes through to shareholders, which means your personal tax liability can be affected by the company’s taxable income even if you did not withdraw all of that profit as cash. Review your year-to-date income, withholding, estimated payments, and projected S Corp income to see whether you are reasonably on track. For a broader look at proactive planning, see our guide to tax planning for small business owners.9. Clean Up Shareholder Transactions
Transfers between an S Corp and its shareholders should be properly identified in the books. Review transactions involving shareholder contributions, distributions, reimbursements, and loans. Personal purchases made through the business account should also be identified rather than left buried in ordinary business expense categories. This is especially important if money frequently moved between your personal and business accounts during the year. Clean records make it easier for your accountant to understand what actually happened and reduce unnecessary questions during tax preparation.10. Meet With Your Tax Professional Before December 31
One of the most useful year-end steps is simply reviewing your numbers while there is still time to act. Your tax professional can look at projected business income, payroll, distributions, estimated taxes, retirement contributions, major purchases, and other factors together rather than treating each decision separately. This is the main difference between tax preparation and tax planning. Tax preparation reports what already happened. Planning gives you an opportunity to consider available options while the year is still open.

Why Year-End Planning Matters for S Corp Owners
An S Corporation can provide useful tax and business-planning opportunities, but the structure also comes with responsibilities. Payroll, compensation, distributions, recordkeeping, and shareholder transactions all need to be handled correctly. Year-end planning gives you an opportunity to review these areas before tax returns are prepared. It can also help you enter the new year with cleaner books, a clearer understanding of your tax position, and fewer surprises during filing season. Every S Corp is different, so decisions should be based on the company’s actual financial situation rather than a generic tax strategy.Get Your S Corp Ready Before Year-End

When should an S Corp start year-end tax planning?
Ideally, an S Corp owner should begin reviewing the company’s financial position during the final quarter of the year. Starting early gives you more time to review payroll, estimated taxes, retirement planning, business expenses, and other items that may require action before December 31.
Does an S Corp owner have to take a salary?
If a shareholder performs services for the S Corporation, reasonable compensation rules generally apply. The appropriate salary depends on the work performed and the circumstances of the business. It should not be based solely on the amount an owner wants to take as distributions.
Are S Corp distributions tax-free?
Not necessarily. S Corp distributions generally are not wages and therefore are treated differently from salary for employment tax purposes, but shareholders can still owe income tax on their share of the company’s taxable income. Distribution treatment can also depend on factors such as the shareholder’s stock basis.
Can an S Corp make year-end retirement contributions?
Potentially, yes. The available options and deadlines depend on the type of retirement plan, the company’s payroll, its employees, and other factors. Business owners should review retirement planning before year-end rather than assuming every contribution can be handled after December 31.
What records should an S Corp prepare before tax season?
Useful records generally include year-end financial statements, bank and credit card reconciliations, payroll reports, shareholder distribution and contribution records, loan information, asset purchases, expense documentation, and estimated tax payment records. Having clean records can make tax preparation considerably more efficient.
