Smart Year-End Tax Saving Strategies for U.S. Businesses and Busy Professionals

The year is quickly heading toward its final stretch. With holiday orders are piling up, work deadlines approaching, and personal commitments competing for your time, the last few weeks of the year always feel like a race. Amidst all this, there’s one more task item that deserves your attention: year-end tax planning.

Most tax saving strategies this year are being shaped by OBBB-related provisions that have changed how businesses look at deductions, expenses, and cash flow planning. Many strategies that worked in prior years now require adjustment and a closer review.

Businesses must evaluate their current tax liability and next year’s cash position before December 31 to stay compliant and profitable. Waiting until tax season may mean losing benefits that can only be claimed with proactive year-end planning.

Here are a few year-end tax strategies you can actually use — even with a packed schedule and the year closing in fast.

11 Year-End Tax Saving Strategies for Business Owners and Professionals

1. Accelerate Your Deductions & Delay Your Income

This is one of the oldest tax strategies that still works. And the idea is super simple:

• Spend money that counts as business expense now (before December 31).
• Push some income into next year, if you can.

As your expenses go up, your taxable income for 2025 will go down.

Some ways to accelerate tax deductions:

• Buy office supplies or equipment if this kind of spend is in the pipeline
• Pay your contractors early
• Buy software subscriptions
• Pay rent or utilities in advance

2.Delay income (if cash flow allows)

If you’re following a cash basis of accounting and expecting a payment, consider sending the invoice in January instead of December. This moves your income to next year and helps reduce your 2025 tax liability.

3.Take Advantage of 100% Bonus Depreciation

One of the biggest tax wins this year came from the One Big Beautiful Bill Act (OBBBA). It has made 100% bonus depreciation permanent for qualifying new and used assets acquired and placed in service after January 19, 2025.

In addition, the section 179 expensing limit has also increased to $2.5 million, with a phase-out beginning at $4 million of total purchases. Provided the asset is put in service by December 31, 2025, to qualify for the current tax year deduction.

As per OBBBA, if you buy big business assets like computers, machinery, tools, office furniture, software, vehicles, you can deduct 100% of the cost immediately. No need to spread deductions over 5–7 years like before.

4.Max Out Your Retirement Contributions

This is one of the easiest, safest, and most powerful tax strategies for Professionals and Individuals. Contribute to SEP, IRA, or Solo 401(k) to save on taxes.

5 Put Money in Your HSA or Use Your FSA

These two accounts often get ignored, but they are tax gold.

Health Savings Account (HSA)

HSA is a triple-benefit account:

• Its contributions are tax-deductible
• The Growth is tax-free
• Withdrawals for medical expenses are tax-free, too.

Flexible Spending Account (FSA)

FSA is a special tax-advantaged account, sponsored by employer for qualified medical expenses that lets you set aside money for certain expenses, like prescription medications, vision and dental work, medical supplies, and child and elder care.

Since you make these out-of-pocket expenses before taxes, your taxable income decreases, and you end up paying less money in taxes.

6.Write Down Obsolete or Slow-Moving Inventory

If you sell products or have stock lying around… year-end is the perfect time to take a stock of your inventory.

If something is damaged, unsellable, or expired, write it down and claim a deduction. This lowers your taxable income and cleans up your balance sheet.4

7.Pay Employee Bonuses Before Year-End

Bonuses paid before December 31 are deductible for this tax year. Plus, they offer two big benefits – your team gets appreciated and you reduce your taxes.

8.Make Charitable Contributions Before Laws Change in 2026

Donations are not only a way to help others; they also lower your taxes.

Additionally, due to OBBBA, charitable contribution rules will become stricter in 2026.

So, if you regularly donate, consider doing more in 2025.

9.Review Your Business Structure

Switching from a sole proprietorship to an LLC, or from an LLC to an S-Corp, could reduce your tax liability. Always review your structure with a tax advisor before year-end to ensure you save more in 2026.

10.Claim Every Tax Credit You Qualify For

This is one of the best entrepreneur tax saving strategies in the US.

Tax credits directly reduce your tax bill — dollar for dollar. So, leverage all possible credits available.

Some common ones include:

• R&D tax credit
• Work Opportunity Tax Credit
• Energy efficiency credits
• EV commercial vehicle credits
• Employer retirement contribution credits

Some credits are changing or being reduced under OBBBA, so year-end is the best time to check what you still qualify for.

11.Review Your Estimated Tax Payments

Underpaying taxes means penalties. Pay them now to avoid surprises later.

Pay estimated taxes if you:

• Have earned more this year
• Took in bigger contracts
• Have expanded your team
• Have added new income streams
