10 Smart Year-End Tax Strategies Every Individual and Small Business Should Use Before December 31
As the year comes to an end, it’s the ideal moment to review your finances and make strategic tax decisions. Whether you’re an individual taxpayer or a small business owner, several high-value tax opportunities expire on December 31. Acting now can help reduce your tax bill, maximize deductions, and position you for a financially stronger new year.
Below are the most essential year-end tax moves you should consider.
1. Increase Your Retirement Contributions
For Individuals
Boosting contributions to tax-advantaged retirement accounts can lower your taxable income:
-
401(k)/403(b): Contribute up to the IRS limit; those 50+ can add catch-up contributions.
-
Traditional IRA: Contributions may be deductible depending on income and employer plan participation.
For Small Business Owners
Business owners can still make deductible contributions to:
-
SEP IRA
-
SIMPLE IRA
-
Solo 401(k)
You may also open certain retirement plans before December 31 even if you plan to fund them later.
2. Review Your Tax Withholding and Estimated Payments
Avoid penalty surprises by checking your withholding or estimated quarterly payments—especially if you:
-
Changed jobs
-
Earned freelance income
-
Sold investments
-
Experienced life changes such as marriage, divorce, or having a child
Small business owners should review Q4 estimated taxes before year-end.
3. Delay Income and Speed Up Deductions
This time-tested tax strategy can lower your current-year tax burden.
Individuals Can:
-
Make January mortgage payments early
-
Donate to charities before December 31
-
Prepay property taxes (if allowed)
Businesses Can:
-
Purchase equipment or supplies needed next year
-
Prepay rent, utilities, or insurance
-
Delay December invoicing to January (if cash-basis)
These timing moves must fit your financial plan, so use them wisely.
4. Claim Section 179 and Bonus Depreciation
If your business buys equipment, vehicles, or software before December 31, you may qualify for:
-
Section 179 expensing
-
Bonus depreciation
Both allow significant immediate deductions, reducing taxable income for the current year.
5. Use Tax-Loss Harvesting
Selling losing investments can help offset taxable gains. Benefits include:
-
Reducing capital gains tax
-
Deducting up to $3,000 of excess losses against ordinary income
-
Carrying forward unused losses indefinitely
Remember: wash-sale rules prohibit rebuying the same or similar investment within 30 days.
6. Make Tax-Smart Charitable Donations
Charitable giving before year-end can provide strong tax savings. You can donate:
-
Cash
-
Appreciated securities
-
Through Qualified Charitable Distributions (QCDs) from IRAs if you’re 70½+
“Bunching” multiple years of donations into a single tax year may push you past the standard deduction threshold.
7. Use Remaining FSA Funds
If you have a Flexible Spending Account (FSA), check your balance now. Many plans follow a “use-it-or-lose-it” rule unless they offer:
-
A grace period, or
-
A limited carryover amount
Book medical, dental, or vision appointments before year-end if needed.
8. Take Required Minimum Distributions (RMDs)
If you’re 73 or older, or inherited a retirement account, RMDs must be taken before December 31. Missing the deadline can result in large IRS penalties.
QCDs can also help satisfy your RMD while lowering taxable income.
9. Organize and Update Your Business Records
Clean books make tax season easier and help you understand your business performance.
Before December 31, small businesses should:
-
Reconcile accounts and categorize transactions
-
Update mileage logs
-
Review payroll and contractor payments
-
Prepare information for 1099-NEC forms
Good recordkeeping reduces filing delays and IRS scrutiny.
10. Schedule a Year-End Review With a CPA
Tax laws change often, and many credits or deductions require action before the new year. A meeting with a CPA now ensures:
-
You capture every eligible tax break
-
You stay compliant with IRS rules
-
You begin the new year with a clear tax strategy
