As we close in on year-end, this is the season when smart business owners pause, take a breath, and make a few intentional moves that can significantly reduce taxes and strengthen long-term wealth.

The new One Big, Beautiful Bill includes several tax updates that can help you lower your tax burden, if you take advantage of them before December 31.

But before we dive into tactics, let’s zoom out for a moment.

Great strategic decisions don’t start with deductions. They start with clarity.

Three Questions Before Acting on Year-end Tax Strategies

At 40 Strategy, we always come back to this idea: alignment creates better outcomes. So, before you start prepaying expenses or moving money around, take a step back and consider the bigger picture.

1. What’s the net benefit, and how does it impact your cash flow?

A tax deduction is only useful if it helps your cash position, not hurts it. Don’t spend $1 to save $0.30 without a real business purpose.

2. Planning to sell your business in the next 3–5 years?

If a sale is on the horizon, showing some taxable income is actually a good thing. Buyers look at the seller's discretionary earnings or EBITDA, the higher the number, the higher your potential valuation.

If your books show little or no taxable income for multiple years, you may unintentionally shrink your company’s value. This is not a pleasant surprise, as we recently had this issue with a new client.

3. Will your tax-saving strategies lock up cash you need?

Some year-end tools (retirement vehicles, certain investments, etc.) pull cash out of your business for long periods of time. Make sure the timing works for your operational needs and strategic goals.

Team Up With Your CPA and Advisor

This is not the time to guess. Coordinate with your CPA and financial advisor to understand:

• Your projected tax liability
  
  

• Your liquidity needs
  
  

• Your retirement “number”
  
  

• Whether aggressive deductions help or hurt your long-game
  
  

If you’re missing a CPA or retirement advisor, 40 Accounting can connect you to the right people.

Top 10 Year-End Moves Every Business Owner Should Make

These are the fundamentals, the things every owner should review before closing the books.

1. Run a Tax Projection (Don’t Guess)

A simple projection gives you visibility and prevents surprises. It should guide every other decision on this list.

2. Make Your Final Estimated Tax Payment (Due January 15)

Get ahead of penalties and cash-flow stress.

3. Max Out Retirement Contributions

Consider an IRA, solo 401(k), or SEP IRA. Sole proprietors with no employees often get the most flexibility and the highest contribution limits.

4. Review Capital Gains and Losses

Harvest losses where appropriate. Reset your investment mix if needed.

5. Prepay Business Expenses (Cash-Basis Taxpayers Only)

If you’re cash-basis, you may be able to pull 2026 expenses, like supplies or software, into 2025 to reduce this year’s taxable income.

6. Accelerate Deductions

This is especially important if your 2025 income will be lower than this year’s.

7. Check Your W-2 Withholdings

Make sure you’re not dramatically under or overpaying.

8. Clean Up Your Bookkeeping

Accurate categorization = accurate returns. This is also the moment to properly document asset purchases or reimbursements.

9. Gather Your Documentation Packet

Invoices, receipts, mileage logs, contracts, asset details, having everything prepared now makes tax season painless.

10. Schedule a Year-End Tax Review

A focused conversation with your CPA can uncover meaningful tax savings you may otherwise miss.

Higher-Value Strategies Worth Considering

These aren’t for everyone, but for the right business owner, they can be powerful tools.

1. Purchase Necessary Assets Before Year-End

Section 179 allows you to deduct up to roughly $2 million of qualifying equipment purchases. And yes, you can finance the asset and still take the deduction now. This is one of the rare situations where you can improve cash flow and reduce taxes.

2. Move From Renting to Owning Your Business Property

Owning creates new tax advantages, including:

• Regular depreciation
  
  

• Accelerated depreciation through cost segregation
  
  

• Potentially greater long-term equity
  
  

Manufacturing companies may see even larger benefits under the new tax law.

3. Defer Income to 2026 (Cash-Basis Only)

If appropriate, consider scheduling payments for January rather than December. The work can happen this year, the payment does not have to.

4. Buy a Qualifying Business Vehicle

Vehicles over 6,000 lbs GVWR (large SUVs, trucks, vans) may qualify for significant year-one deductions through Section 179 or bonus depreciation. For the right business, this can be a substantial tax savings event. The author may or may not have a new business vehicle due to this tax law.

Year-end can feel rushed, but making the right strategic decisions now creates clarity, confidence, and financial momentum heading into 2026.
