Daperis CPASpecialized Accounting for Doctors, Consultants & Creative Professionals
High income creates its own category of tax problems, and they're not the ones most general small business content ever covers. If you're a doctor, a consultant with equity in a client's startup, or a creative professional with an inconsistent but high-earning year, the issues you're actually running into look more like equity compensation, phase-outs on retirement contributions, and deductions that are worth less than they used to be simply because you're in the top bracket. Here's the landscape.
Equity Compensation
Consultants and advisors who take equity, RSUs, options, or advisory shares, from a client or startup are dealing with a genuinely different tax picture than a straight cash fee. When that equity vests, and how it's taxed when it does, depends on the type of grant, and the decisions you make in the year you receive it, like whether to file an 83(b) election on early-stage equity, are time-sensitive and generally can't be undone once the window closes. See the Equity Compensation article for how each type actually gets taxed.
The Backdoor Roth, and Why the Pro-Rata Rule Trips People Up
High earners are phased out of contributing directly to a Roth IRA, which is why the "backdoor Roth" workaround, contributing to a traditional IRA and then converting it, exists in the first place. Here's the part that catches people: the pro-rata rule. If you have any other pre-tax IRA money sitting anywhere, even in an old rollover IRA you forgot about from a job you left a decade ago, the IRS treats your conversion as a proportional mix of pre-tax and after-tax dollars, not the clean, fully tax-free conversion most people expect. See the Backdoor Roth IRA Pro-Rata Rule article before you attempt this, it's the single most common way this strategy gets executed wrong.
HSAs, a Genuinely Underused Account
If you're on a high-deductible health plan, an HSA gives you a deduction going in, tax-free growth, and tax-free withdrawals for medical expenses, three tax benefits stacked on one account, more than either a 401(k) or a Roth IRA offers alone. It's also one of the most overlooked accounts among high earners who default to maxing a 401(k) and stop there. See the HSA guide for contribution limits and a strategy some people use to let the account grow for decades before touching it.
The New Cap on What Your Itemized Deductions Are Actually Worth
If you're in the top tax bracket with real itemized deductions, state taxes, mortgage interest, charitable giving, a recent change shaved a couple of points off the actual value of those deductions starting with 2026. It's narrow, only touching people already in the top bracket with meaningful itemized deductions, but if that's you, the number you're used to using to estimate your tax savings isn't accurate anymore. See the Itemized Deduction Limitation article for the mechanics.
Where Should Idle Cash Actually Sit?
High earners often accumulate meaningful cash between tax payments, bonus timing, or between investments, and where that cash sits matters more than people assume, particularly around state tax treatment. See the Treasury Money Market Fund vs. HYSA article for how the state tax treatment differs between the two, and when one genuinely beats the other for your situation.
Why Do These All Belong in the Same Conversation?
Because none of these issues exist in isolation for a high earner. An RSU vesting event changes your income for the year, which changes whether the itemized deduction cap applies to you, which changes the math on a backdoor Roth conversion you might be planning that same year. Treat each of these as a separate, one-off question, and you end up with pieces that are technically correct but poorly coordinated across your whole return.
Keep It Simple / Key Takeaway 🍕
High-earner tax planning isn't about finding one clever move. It's about the fact that your income, equity, retirement contributions, and deductions all interact with each other in ways a lower-income return simply doesn't have to deal with. Get familiar with each piece using the guides above, then bring the full picture to your CPA rather than solving each one in isolation.
