As the year wraps up, it’s the perfect time for small business owners to take a proactive approach to tax planning. The actions you take before December 31 can significantly reduce your tax bill and set you up for a stronger financial start in the new year.
Here’s your Small Business Year-End Tax Checklist to help you identify savings opportunities, clean up your books, and plan ahead.
1. Review Your Business Structure — Is It Time for an S Corp?
If your business is earning over $50,000 in annual net income, it may be time to consider electing S Corporation status.
An S Corp structure allows business owners to pay themselves a reasonable salary while taking additional profits as distributions, which are not subject to self-employment tax. This can lead to thousands of dollars in annual tax savings.
Tip: The S Corp election must be filed properly and maintained through payroll compliance — talk to your CPA before year-end to see if it makes sense for 2025.
2. Max Out Retirement Contributions
One of the most effective ways to reduce taxable income is through retirement plan contributions:
Solo 401(k): Up to $69,000 total (employee + employer) for 2024 ($76,500 if 50+).
SEP IRA: Up to 25% of W-2 wages, maxing out at $69,000.
Defined Benefit Plan: A powerful tool for high-income earners seeking six-figure deductions.
Example: A consultant earning $120,000 who contributes $25,000 to a retirement plan could save roughly $8,000–$9,000 in federal taxes, depending on their bracket.
3. Reimburse Business Expenses Through an Accountable Plan
If you’ve personally paid for business-related expenses—such as your home office, cellphone, internet, or business mileage—set up an Accountable Plan to reimburse yourself before year-end. Reimbursements are deductible to your business and tax-free to you.
4. Evaluate Year-End Equipment, Asset, or Vehicle Purchases
If your business is planning to invest in equipment, computers, furniture, or vehicles, now may be the time.
Under 100% bonus depreciation (available through 2025) and Section 179 expensing, qualifying assets can often be fully deducted in the year of purchase.
Tip: Only purchase what your business truly needs — but smart timing before year-end can provide a major tax deduction for 2025.
5. Verify Estimated Tax Payments and Clean Up Your Books
Review your federal and state estimated payments for accuracy.
Reconcile your bank and credit card accounts.
Correct any miscategorized or personal expenses in your books.
Ensure your accounting is ready for year-end reporting and tax filing.
