Mid-Year Tax Planning Checklist for Small Business Owners

Tax planning that moves the needle has to happen while there's time to act

By the time tax season rolls around, most of your options are gone. That's exactly why the second half of the year matters so much. Here's what we walk clients through this time of year.

1. Review year-to-date profit against last year

Are you tracking ahead or behind where you were this time last year? This single number drives almost every other decision on this list, from estimated payments to entity structure to retirement contributions.

2. Revisit your estimated tax payments

If your income has shifted since your first estimated payment, your remaining payments should shift too. This is the easiest way to avoid an unpleasant surprise, or an unnecessary penalty, next spring.

3. Look at major purchases before year-end

If you're planning equipment purchases, software, or other deductible expenses, timing matters. Depending on your situation, accelerating a purchase into this year versus waiting until January can change your tax outcome meaningfully.

4. Check your retirement contributions

Retirement plans like a SEP IRA or Solo 401(k) are one of the most effective ways to reduce taxable income while building long-term savings. Contribution limits and deadlines vary by plan type and change periodically, so this is worth confirming for the current year rather than assuming last year's numbers still apply.

5. Consider your entity structure

If your profit has grown significantly this year, this is a good time to revisit whether your current business structure, sole proprietorship, LLC, S-Corp, still makes sense. Entity elections and conversions have their own timing rules, so this is worth discussing well before year-end rather than in the final weeks of December.

6. Clean up your books now, not in January

Every one of the items above depends on having accurate, current financials. If your books are behind, this is the moment to catch up, while there's still time to actually use the information.

7. Talk to your accountant before you need to

The biggest difference between tax preparation and tax planning is timing. Preparation looks backward at what already happened. Planning looks at what's still changeable. The second half of the year is when planning still works.

We do a mid-year check-in with clients for exactly this reason. If you haven't had one yet, request a financial assessment and let's get something on the calendar.
