End-of-Year IRS Tax Tips: How to Reduce Your 2024 Tax Bill Before December 31
As the year draws to a close, millions of Americans are searching for ways to legally reduce their tax bill before the clock strikes midnight on December 31, 2024. With the IRS announcing inflation-adjusted changes, higher standard deductions for 2025, and new tax rules affecting credits and retirement plans, November and December are the most important months to plan your taxes.
Whether you’re a salaried employee, small business owner, freelancer, or investor, there are IRS-approved strategies you can still take advantage of—but only before year-end.
This comprehensive guide breaks down the best end-of-year IRS tax tips, backed by expert analysis and current IRS guidelines.
1. Why Year-End Tax Planning Matters
Most tax-saving strategies must be completed before December 31, not tax day in April. According to recent IRS behavioral reports, over 55% of taxpayers leave money on the table simply because they wait until filing season.
The reason year-end planning is powerful:
✔ You still have time to adjust income
✔ You can increase deductions
✔ You can claim credits that phase out once the year ends
✔ You can reduce taxable income strategically
2. IRS Updates for 2024–2025: What Taxpayers Should Know
Here are key IRS updates affecting 2024 filings:
✅ Higher Standard Deduction
For filing in 2025 (for 2024 taxes):
- Single: $14,600
- Married: $29,200
- Head of Household: $21,900
✅ Increased Retirement Contribution Limits
401(k): $23,000
IRA: $7,000
Catch-up contributions (50+): +$7,500 for 401(k)
✅ Inflation-Adjusted Tax Brackets
Slightly wider brackets = more room for tax savings.
These adjustments make end-of-year tax planning even more valuable, especially for middle-income earners.
3. Maximize Your Retirement Contributions
Contributing to retirement accounts is one of the simplest ways to lower taxable income.
✔ 401(k) Contributions Reduce Taxable Income
For example:
If you contribute $5,000, you reduce your taxable income by $5,000.
✔ IRA Deadline: April 2025
But Roth conversions & 401(k) contributions must be done by December 31.
✔ Consider Roth Conversions
If your 2024 income is lower than usual, converting traditional IRA funds to Roth may offer long-term benefits.
4. Take Advantage of Tax-Loss Harvesting
If you invest in stocks, ETFs, or crypto, this IRS strategy is powerful:
✔ Sell Losing Investments to Offset Gains
You can subtract up to:
- Unlimited capital gains offset, plus
- $3,000 against ordinary income
Crypto investors can also benefit due to ongoing price volatility.
5. Boost Itemized Deductions Before December 31
If you itemize, these deductions must occur before year-end:
✔ Mortgage interest
✔ Medical expenses (must exceed 7.5% AGI)
✔ State and local taxes (SALT cap: $10,000)
✔ Charitable donations
✔ Property taxes
Pro Tip:
If your expenses fall just short of itemizing, consider bunching—paying 2025 expenses early.
6. Claim IRS-Approved Tax Credits
⭐ Child Tax Credit
Up to $2,000 per qualifying child
⭐ Earned Income Tax Credit (EITC)
Benefits low to moderate-income workers
⭐ Energy Tax Credits
Home improvement, solar panels, EV purchases
⭐ American Opportunity Credit (AOTC)
Up to $2,500 for education
Credits directly reduce the tax you owe—some even produce refunds.
7. Make Strategic Charitable Donations
Charitable donations made by December 31 can reduce your taxable income.
Ways to donate:
✔ Cash contributions
✔ Donated clothing/household items
✔ Securities (appreciated assets)
✔ Donor-Advised Funds (DAFs)
8. Maximize HSA and FSA Accounts
⭐ HSA Limit 2024
- Individual: $4,150
- Family: $8,300
⭐ FSA “Use It or Lose It”
Spend remaining amounts before they expire.
9. Run an IRS Withholding Check-Up
If you got a new job, changed income, or had kids, check your IRS withholding using the IRS Withholding Estimator.
Adjusting in November or December prevents:
❌ Unexpected tax bills
❌ Underpayment penalties
10. IRS End-of-Year Tips for Small Business Owners
Small businesses can reduce taxes with:
✔ Section 179 expensing
✔ Business equipment purchases
✔ Home office deduction
✔ Vehicle mileage deduction
✔ Bonus depreciation
11. IRS Tips for Gig Workers, Freelancers & Independent Contractors
Gig economy workers must:
✔ Track all income
✔ Write off business expenses
✔ Pay quarterly taxes (final payment due January 15, 2025)
Common deductions:
- Internet
- Laptop
- Home workspace
- Apps and tools
- Travel & mileage
12. Avoid These IRS Audit Triggers
- Unreported income (IRS gets your 1099s too)
- Excessive deductions
- Large charitable donations without receipts
- Mixing personal and business expenses
13. Plan for 2025: Preparing Ahead
Things to consider:
✔ New IRS tax brackets
✔ Upcoming credit changes
