Tax Planning for High Income Earners: Strategies That Connect to Your Wealth Plan
Effective tax planning for high income earners looks different from planning for households with large accumulated assets. Physicians, attorneys, executives, engineers and business owners often earn substantial income while still building their net worth, and much of that income is taxed in higher brackets. Without a plan, a large share of each raise or bonus can go to taxes before it ever reaches an investment account. The good news is that many of the most useful strategies are about coordination: aligning how you earn, save, invest and give.
For professionals and families in Madison, Milwaukee, Waukesha and across Wisconsin, this guide outlines the main levers to discuss with a tax and investment professional. To look at how these ideas apply to your own income and portfolio, you can request a complimentary, no-obligation wealth and tax review.
Why Tax Planning for High Income Earners Is Different
High earners often encounter rules that do not affect most taxpayers. Income above thresholds set by the IRS may trigger the net investment income tax, an additional Medicare tax on wages, phase-outs of certain deductions and credits, and limits on direct Roth IRA contributions. Many of these thresholds are based on modified adjusted gross income, which makes it a number worth tracking each year.
At the same time, high earners tend to have more complex compensation: bonuses, equity grants, deferred compensation and business distributions. Each arrives with its own timing and tax treatment. Proactive tax planning and preparation looks ahead at these items before the year closes rather than simply reporting them afterward.
Consider a hypothetical dual-income couple in Brookfield: one spouse is a hospital physician and the other a corporate executive with annual stock grants. Their combined wages, bonuses and vesting shares can push them into higher brackets, expose investment income to additional tax and phase them out of benefits they once used. A coordinated plan might look at how much each spouse defers into workplace plans, when equity is sold, how the taxable portfolio is positioned and whether charitable goals could be funded more efficiently. None of these choices is complicated on its own, but together they can meaningfully shape both the tax bill and the pace of wealth building.
Make the Most of Tax-Advantaged Accounts
Retirement and health accounts are often the first line of defense:
Workplace retirement plans: Contributing to a 401(k) or 403(b) may reduce current taxable income, with annual limits that apply to employee and employer contributions.
Backdoor Roth IRA: Because high earners may be ineligible to contribute directly to a Roth IRA, some use a nondeductible traditional IRA contribution followed by a conversion. Existing pre-tax IRA balances can complicate this, so careful review matters.
After-tax 401(k) contributions: Some plans permit additional after-tax contributions that can be converted to Roth, sometimes called a mega backdoor Roth.
Health savings accounts: If paired with a qualifying high-deductible health plan, an HSA may offer deductible contributions, tax-deferred growth and tax-free withdrawals for qualified medical costs.
Deferred compensation plans: Executives may be able to defer part of their pay to future years, though these plans carry employer credit risk and should be evaluated carefully.
Coordinate Equity Compensation With Your Portfolio
Restricted stock units, stock options and employee stock purchase plans can create large, sometimes unexpected tax bills. RSUs, for example, are generally taxed as ordinary income when they vest, and default withholding may not cover the full liability for someone in a higher bracket. Our guide to restricted stock unit taxes explains how this works.
Equity compensation is also an investment concentration question. Holding a large position in one employer's stock can increase risk, so decisions about when to sell, how to diversify and how to manage the resulting capital gains should be made with both taxes and the broader portfolio in mind. Integrated wealth management can help weigh those trade-offs together.
Invest With Taxes in Mind
As taxable investment accounts grow, the tax efficiency of the portfolio itself becomes more important. Approaches that may help include:
Holding tax-inefficient assets in tax-deferred accounts and tax-efficient funds in taxable accounts.
Harvesting losses to offset realized gains.
Considering municipal bonds, including Wisconsin-specific considerations, where appropriate for your bracket.
Managing the timing of gains and favoring long-term holding periods.

Use Charitable Giving Strategically
Many high earners give regularly but take the standard deduction in some years. Bunching several years of gifts into one year, often through a donor-advised fund, may allow itemizing in that year while still supporting charities over time. Donating appreciated securities rather than cash can also avoid capital gains on the donated shares. A hypothetical surgeon in La Crosse with a strong bonus year, for instance, might consider funding a donor-advised fund that year with appreciated stock from a concentrated position.
Planning for Business Owners and Self-Employed Professionals
Business owners and partners have additional options. Entity choice, reasonable compensation for S corporation owners, the qualified business income deduction, retirement plans such as cash balance or solo 401(k) arrangements, and the timing of equipment purchases can all influence taxable income. Wisconsin's pass-through entity tax election may also be worth evaluating. Because these decisions affect both the business and the owner's personal wealth plan, they work best when tax and investment advisors are aligned.
As income turns into significant assets, the focus often broadens to estate and multigenerational planning, covered in our article on tax planning strategies for high-net-worth individuals. Estate and trust decisions should be coordinated with an estate planning attorney.

Frequently Asked Questions
When should tax planning for high income earners begin?
Tax planning for high income earners works best when it starts early in the year and continues through year end. Many opportunities, such as retirement contributions, charitable bunching, equity compensation decisions and loss harvesting, depend on timing. Waiting until filing season often limits options to reporting what already happened rather than shaping the outcome. Quarterly or mid-year check-ins can help.
What is a backdoor Roth IRA?
A backdoor Roth IRA is a strategy where someone makes a nondeductible contribution to a traditional IRA and then converts it to a Roth IRA. It is often used by people whose income exceeds the limits for direct Roth contributions. Existing pre-tax IRA balances may make part of the conversion taxable under the pro-rata rule, so reviewing all IRA accounts first is important.
Are high earners more likely to owe at tax time?
Often, yes. Bonuses, equity compensation and investment income may not have enough tax withheld, especially for people in higher brackets. This can lead to a balance due and potential underpayment penalties. Reviewing withholding and making estimated payments during the year can help. A tax professional can project your liability and suggest adjustments before deadlines pass.
How does investing connect to tax planning?
Investment decisions create taxable events through interest, dividends and realized gains. Where assets are held, how long they are held and when they are sold can all affect your tax bill. Coordinating investment management with tax planning can help reduce unnecessary tax drag, manage concentrated positions and support long-term goals such as retirement, education funding and charitable giving.
