1. Start with a Pro-Forma Tax Snapshot (Non-Negotiable)
Before making any move, understand where you stand.
What to do:
-
Ask your CA/CPA to run a draft 2025 tax computation
-
Include:
-
Year-to-date income
-
TDS/withholding
-
Capital gains
-
Deductions already used
-
Why it matters:
-
Confirms your current tax bracket
-
Helps decide whether to defer income or accelerate deductions
-
Crucial if 2026 tax rates or rules change under new laws
2. Max Out Tax-Advantaged Accounts Before Year-End
This is often the fastest legal tax saver.
Priority Contributions (Check 2025 limits):
Retirement
-
US: 401(k), IRA, Roth (backdoor), SEP
-
India: EPF, NPS, PPF
-
Employer match = free money (don’t miss it)
Health & Education
-
HSA / FSA
-
529 education plans (where applicable)
👉 These reduce taxable income now and compound tax-efficiently for the future.
3. Use Tax-Loss Harvesting Before 31 December
Review your investment portfolio carefully.
You can offset:
-
Capital gains from stocks, mutual funds, real estate
-
Limited ordinary income (e.g., up to $3,000/year in the US)
Important rules:
-
Avoid wash-sale violations
-
Switch into a similar (not identical) fund or ETF to stay invested
📉 Booking losses strategically today can save thousands in tax tomorrow.
4. Time Income & Deductions Strategically
Your future tax bracket determines your move.
If 2026 tax rate likely same or lower
-
Defer bonuses, invoices, or business income to early 2026
-
Prepay deductible expenses in 2025:
-
Insurance
-
Office rent
-
Professional fees
-
Property tax (where allowed)
-
If 2026 tax rate likely higher
-
Accelerate income into 2025
-
Delay discretionary deductions to 2026
This is especially critical with deduction caps and rule changes starting 2026.
5. Bunch Charitable Donations for Bigger Deductions
Instead of donating small amounts every year:
-
Combine 2–3 years of donations into 2025
-
This may push you beyond the standard deduction and make itemizing worthwhile
Advanced options:
-
Donor-advised funds
-
Gifting appreciated securities (may avoid capital gains)
6. Plan Ahead for 2026 Tax Law Changes
2025 is the last full planning year before multiple rule changes.
Potential changes may include:
-
SALT cap revisions
-
Changes in charitable deduction limits
-
Sunsetting individual tax cuts
-
New depreciation and business relief rules
Smart December moves:
-
Buy eligible business equipment in 2025 (bonus depreciation)
-
Consider realizing major gains in 2025 if future rates rise
7. Clean Up ESOPs, RSUs & Crypto Before Year-End
These are high-risk areas for mistakes.
Key actions:
-
Decide whether to exercise stock options in 2025
-
Start long-term capital gains holding clock early
-
Harvest crypto losses
-
Track every transaction carefully
-
Check AMT or minimum tax exposure
⚠️ These areas face strict scrutiny—planning beats penalties.
8. Review Gifting, Estate & Beneficiaries
Year-end is ideal for legacy planning.
Checklist:
-
Use annual gift exemptions
-
Update:
-
Will
-
Nominees

Beneficiaries (demat, MF, insurance, retirement)
-
With estate thresholds potentially changing, early planning preserves wealth.
