Tax Season Checklist: What High-Income Earners Need to Do Before Filing

February 05, 2025

For high-income earners, tax season involves more than just submitting a return—it’s a time to maximize deductions, minimize liabilities, and ensure compliance with evolving tax laws. With the April 15, 2025, tax deadline approaching, reviewing key tax-saving strategies can help optimize efficiency and avoid unnecessary penalties.

This checklist outlines essential steps for high-income individuals, business owners, and affluent investors to take before filing their 2024 tax return while preparing for the 2025 tax year.

1. Gather Essential Tax Documents

Proper record-keeping is crucial for filing an accurate tax return and avoiding delays or audits. High-income earners often receive multiple forms that require careful review:

  • Income Statements:
    • W-2s for salaried earnings
    • 1099-NEC for self-employment income
    • K-1s for partnership, S-corporation, or trust income
  • Investment Statements:
    • 1099-DIV (dividends), 1099-INT (interest), and 1099-B (capital gains/losses)
  • Retirement Contributions: 401(k), IRA, SEP-IRA, or other tax-advantaged account contributions
  • Real Estate & Mortgage Documents: Form 1098 for mortgage interest deductions
  • Charitable Donation Receipts: If itemizing deductions

For those with complex financial situations, working with a tax professional can help ensure all necessary documents are accounted for.

2. Maximize Tax-Advantaged Retirement Contributions

Contributing to tax-advantaged retirement accounts is one of the most effective ways to reduce taxable income for high earners.

  • 401(k) Contributions: The 2024 contribution limit was $23,000 (or $30,500 for those age 50+) (IRS, 2024). The deadline for making contributions was December 31, 2024.
  • IRA Contributions: The contribution limit for 2024 is $7,000 ($8,000 for age 50+), and contributions can still be made until April 15, 2025 (IRS, 2024).
  • Backdoor Roth IRA: High-income individuals exceeding Roth IRA income limits ($161,000 for single filers and $240,000 for married couples filing jointly in 2024) can use the backdoor Roth strategy, which involves contributing to a non-deductible traditional IRA and converting it to a Roth IRA (IRS, 2024).
  • SEP IRA and Solo 401(k): Self-employed individuals can contribute up to 25% of compensation or $69,000 (whichever is lower) to a SEP IRA for the 2024 tax year. Solo 401(k) contributions allow even higher savings potential with employer and employee contributions combined (IRS, 2024).

3. Utilize Tax-Loss Harvesting to Offset Gains

If you realize investment losses in 2024, you can use tax-loss harvesting to offset capital gains and reduce taxable income.

  • Offset capital gains: Realized losses can offset equal capital gains.
  • Reduce ordinary income: If losses exceed gains, up to $3,000 can be deducted, with any excess carried forward to future tax years.
  • Watch the wash-sale rule: If you sell a security at a loss, the IRS prohibits repurchasing a "substantially identical" asset within 30 days before or after the sale (IRS, 2024).

Strategic tax-loss harvesting can help high-income investors manage their taxable investment income efficiently.

4. Optimize Charitable Contributions

Strategic giving can provide meaningful tax benefits for those who donate to charity.

  • Itemized Deduction vs. Standard Deduction: The standard deduction 2024 is $14,600 for single filers and $29,200 for married couples filing jointly (IRS, 2024). Those who exceed this threshold may benefit from itemizing deductions.
  • Bunching Donations: By grouping multiple years' worth of donations into a single tax year, taxpayers may surpass the standard deduction and maximize charitable tax benefits.
  • Donor-Advised Funds (DAFs): Contributing to a DAF allows donors to take an immediate tax deduction while distributing funds to charities over time.
  • Qualified Charitable Distributions (QCDs): Individuals age 70½ or older can donate up to $105,000 directly from an IRA to a qualified charity, reducing taxable income and satisfying required minimum distributions (RMDs) (IRS, 2024).

5. Assess Tax Brackets and Additional Taxes

High-income earners are subject to additional taxes that may increase overall liability:

  • The 3.8% Net Investment Income Tax (NIIT) applies to investment income for individuals earning over $200,000 (or $250,000 for married couples filing jointly) (IRS, 2024).
  • The 0.9% Additional Medicare Tax applies to wages and self-employment income above the same thresholds.
  • Capital Gains Tax Considerations: Long-term capital gains are taxed at 15% or 20%, depending on income, while short-term gains are taxed at ordinary income rates.

Understanding where you fall in these tax brackets can help guide tax-saving decisions, such as deferring income or accelerating deductions.

6. Plan for Estimated Taxes and Avoid Penalties

Estimated tax payments may be necessary to avoid penalties if you earn significant non-W2 income, such as self-employment or investment income.

  • The IRS requires taxpayers to pay at least 90% of their current year’s tax liability or 100-110% of the previous year's tax bill (IRS, 2024).
  • Estimated tax payments 2024 were due April 15, June 15, September 15, 2024, and January 15, 2025.
  • If underpaid, adjusting 2025 quarterly payments can prevent future penalties.

7. Identify Overlooked Deductions and Credits

Several tax deductions and credits may be available:

  • Health Savings Account (HSA): Contributions up to $4,150 (individual) or $8,300 (family) are tax-deductible for 2024, with an additional $1,000 catch-up contribution for those age 55+ (IRS, 2024).
  • 529 Plan Contributions: Some states offer tax benefits for contributions to education savings plans.
  • Home Office Deduction: Self-employed individuals who use part of their home exclusively for business may be eligible for a home office deduction.

Reviewing available deductions can help reduce overall taxable income.

8. Work with a Tax and Financial Advisor

Tax strategies should be integrated into a broader financial plan for high-income earners. A tax advisor or financial planner can:

  • Ensure compliance with IRS regulations.
  • Identify personalized strategies for tax efficiency.
  • Coordinate tax planning with investment and estate planning strategies.

Conclusion
