10 Moves Smart Business Owners Make Before December 31
December Is Not a Month — It’s a Deadline
Every year, business owners make two mistakes:
- They think tax season starts in April.
- They believe accountants perform miracles.
Here’s the truth:
💡 April is just reporting season. December is decision season.
What you do in the next few weeks determines:
- how much tax you’ll pay
- how wealthy you’ll look on paper
- and how stressed you’ll be in the spring
There’s no “fix it later” button in tax planning.
So here it is: your tax survival checklist, packed with the exact moves CFO-minded business owners make before the ball drops.
1. Clean Up Your Books (Or Nothing Else Matters)
You can’t plan with messy data.
If your books are behind, inaccurate, or full of “ask my accountant” categories, your tax return becomes a guessing game… and the IRS always wins the guessing game.
Before December 20:
✔ Reconcile all accounts
✔ Categorize every transaction
✔ Match payroll totals
✔ Review your profit & loss
✔ Run a balance sheet health check
🧠 Your tax strategy is only as good as the numbers feeding it.
2. Get a Tax Projection — Your December Crystal Ball
This is where the magic happens.
A proper tax projection tells you:
- how much tax you owe
- where your profit is landing
- which strategies still work
- which levers you can legally pull before 12/31
When clients tell us, “I wish I knew this earlier,” it always means they skipped this step.
🎯 You cannot avoid tax surprises if you refuse to look ahead.
3. Optimize Income Timing
This is NOT tax evasion — it’s tax timing.
If you’re a cash-basis business, you still have time to:
✔ Delay invoicing until January
✔ Push large deposits into next year
✔ Accelerate necessary expenses
If you’re on accrual, your strategy changes:
✔ Invoice NOW if you want income recognized this year
✔ Move vendor payments strategically
💡 The wealthy don’t avoid taxes. They schedule them.
4. Prepay Key Expenses
Every business has recurring, predictable costs:
📌 rent
📌 insurance
📌 software
📌 coaching / consulting
📌 contractor fees
📌 subscriptions
Prepaying 30–90 days of necessary expenses reduces taxable profit today without unnecessary spending.
⚠️ Don’t go on a December buying spree.
Only prepay what you will 100% use.
5. Maximize Retirement Contributions
This is the closest thing to a legal cheat code the IRS offers.
- Solo 401(k) → up to $66,000
- SEP IRA → up to 25% of compensation
- Defined Benefit Plan → six-figure contributions possible
Every dollar reduces taxable income and builds your future.
🧠 High-net-worth clients rarely skip this one.
6. Use the Accountable Plan (If You Don’t, You’re Overpaying)
An accountable plan lets your business reimburse you tax-free for:
✔ home office
✔ cellphone
✔ internet
✔ mileage
✔ equipment
✔ medical (with a proper plan)
If you don’t have a written accountable plan, you cannot legally reimburse yourself this way.
💥 This is one of the biggest mistakes small businesses make.
7. Consider Strategic Equipment Purchases
Section 179 and bonus depreciation are still powerful.
Smart purchases include:
🖥️ computers
📷 cameras
🚐 commercial vehicles
🛠️ machinery
🪟 office improvements
⚠️ Only buy equipment that increases efficiency or revenue.
December regret purchases are not tax strategy.
8. Review Payroll & Owner Compensation
You still have time to adjust:
✔ reasonable compensation
✔ officer health premiums
✔ year-end bonuses
✔ fringe benefits
✔ reimbursable expenses
Your payroll strategy impacts:
- your tax bracket
- your benefits
- your audit risk
- your year-end profit profile
📌 Don’t wait until January — that’s too late.
9. Fix Your Entity Structure Before the Year Closes
If your structure is wrong, your taxes are wrong.
This is the time to evaluate whether you should:
✔ move from S-Corp to C-Corp
✔ add a management or holding company
✔ separate high-risk activities
✔ adjust ownership structure
✔ prepare for 2025 tax positioning
💡 Structure = strategy.
You can make more money by changing your entity than by changing your revenue.
10. Schedule Your January 1–March 31 Playbook
Smart owners use December to set up Q1 for:
- tax-advantaged benefits
- asset acquisition schedules
- cash flow restructuring
- profit allocation percentages
- team development and leadership structure
- personal wealth goals
Most owners drift into January unprepared.
CFOs intentionally design Q1.
💥 Bonus: The December Danger Zone Checklist
Avoid these at all costs:
❌ Waiting until April to think about taxes
❌ Spending money just to “write it off”
❌ Allowing profit to sit idle
❌ Rushing payroll changes
❌ Ignoring fringe benefits
❌ Not meeting with your tax strategist
❌ Assuming your accountant can “fix it later”
⚠️ Once December 31 passes, 90% of tax opportunities are gone.
