Year-End Tax Planning: Last-Minute Strategies Before Dec 31
In the tax landscape, December 31st isn’t just a countdown to the New Year, it’s the hard deadline for nearly all tax-saving actions under the One Big Beautiful Bill Act (OBBBA) in the U.S. and the Finance Act 2026 in India. Because 2026 introduced new deduction “floors” and permanent credit extensions, your year-end checklist must be more precise than ever.
Here are the high-impact moves to make before the ball drops.
The “Charitable Bunching” Maneuver
The OBBBA introduced a 0.5% AGI floor for charitable deductions in 2026. If you earn $200,000, your first $1,000 in donations are no longer deductible.
- The Strategy: Instead of giving $5,000 every year, “bunch” your donations. Give $10,000 this year to a Donor-Advised Fund (DAF).
- The Benefit: You clear the 0.5% floor and the standard deduction threshold in 2026, then use the DAF to distribute the money to charities over the next two years.
- Deadline: The check must be mailed or the credit card charged by midnight on Dec 31.
Maximize the “Mega Backdoor” and 401(k) Limits
For 2026, the 401(k) contribution limit is $24,000 ($31,500 if age 50+).
- The Checklist: Check your last few paystubs. If you haven’t hit the limit, ask your HR to increase your final December withholding.
- Employer Match: Ensure you’ve contributed enough to capture the full employer match, it’s essentially a 100% return on investment.
- HSA Catch-up: If you have a High Deductible Health Plan, the 2026 HSA limit is $4,300 (Individual) or $8,550 (Family). Unlike the 401(k), you have until April 15, 2027, to fund this, but doing it by Dec 31 simplifies your year-end bookkeeping.
India-Specific: The ₹1.25 Lakh “Harvesting” Reset
For our NRI clients and Indian residents, the end of the calendar year is the best time to review your equity portfolio.
- The Rule: Under current Indian law, the first ₹1.25 Lakh of Long-Term Capital Gains (LTCG) on stocks and mutual funds is tax-free annually.
- The Move: If you have unrealized gains, sell enough to “harvest” the ₹1.25 Lakh profit and immediately buy back the same assets.
- The Benefit: You reset your cost basis higher for free, legally reducing the tax you will pay when you eventually exit the position years from now.
Fund the “Trump Account” (Form 4547)
New for 2026, these tax-deferred accounts for children are a powerful year-end tool for parents.
- The Limit: You can contribute up to $5,000 per child per year.
- Why Now? While the growth is tax-deferred, the annual contribution window is based on the calendar year. Missing the Dec 31 deadline means you lose that $5,000 “tax-shelter” slot forever.
- Seed Check: If you had a child in 2025 or 2026, ensure you’ve filed the paperwork to claim the $1,000 government seed contribution.
For Small Business Owners: Section 179 and Bonus Depreciation
If your business needs equipment, furniture, or tech, the OBBBA has extended favorable rules for 2026:
- The Strategy: Purchase and place in service qualifying equipment before Dec 31.
- The Benefit: You can potentially deduct 100% of the cost in 2026 rather than depreciating it over several years.
- Crucial Rule: The item must be “ready for use.” Simply buying a laptop on Dec 31 doesn’t count if it’s still in the box in your garage; it must be set up and available for business use.
How KKCA Secures Your Status
We provide a “Final Countdown” audit in the last two weeks of December:
- The “Floor” Test: We calculate your projected AGI to see if you will clear the 0.5% charitable floor, advising you on whether to “bunch” or wait.
- Wash Sale Protection: If you are tax-loss harvesting, we ensure you don’t trigger the 30-day Wash Sale Rule, which would disallow your loss deduction.
- Global Sync: We coordinate your U.S. and Indian year-end moves so that a gain harvested in India doesn’t create an unexpected tax liability on your U.S. return.

Frequently Asked Questions (FAQ)
Q: Can I pay my property taxes now to get a deduction? A: Only if the tax has actually been assessed by your municipality. The OBBBA maintains the $40,400 SALT cap, so ensure you haven’t already hit that limit before prepaying.
Q: Do I need to sell my stocks by Dec 31 to claim a loss? A: Yes. For a loss to be “realized” for the 2026 tax year, the trade must execute by the last business day of the year.
Q: What is the Dec 31 deadline for RMDs? A: If you are 73 or older, you must take your Required Minimum Distribution (RMD) by Dec 31 to avoid a 25% penalty. If this is your first RMD, you have a one-time extension until April 1.
