Smart Tax Strategies for Physicians: Boost Income & Reduce Tax Burden for 2025

Physicians are advised to restructure their financial planning for the 2027 tax year following the expiration of the Tax Cuts and Jobs Act (TCJA) on December 31, 2025. According to accountants cited by Medscape, doctors must now seek alternative strategies to lower taxable income after the loss of the 20% Qualified Business Income (QBI) deduction and the return of higher individual tax brackets.

The expiration of the TCJA provisions means that the tax landscape for medical professionals changed significantly starting January 1, 2026. Because the 2026 tax year is currently underway, financial advisors are urging physicians to make adjustments now to mitigate the tax burden they will face when filing in 2027.

Why did physician tax burdens increase after 2025?

The primary driver of increased tax liability is the “sunset” of the TCJA, a law passed in 2017 that lowered individual income tax rates and increased the standard deduction. On December 31, 2025, these provisions expired, causing individual tax rates to revert to their higher, pre-2018 levels.

According to Internal Revenue Service (IRS) guidelines, the expiration also reduced the standard deduction, which forces more physicians to itemize their deductions to achieve similar tax savings. This shift effectively increases the taxable income for high-earning medical professionals who previously relied on the higher standard deduction.

How does the loss of the QBI deduction affect medical practices?

The most significant loss for physicians in partnerships or S-corporations is the Section 199A Qualified Business Income (QBI) deduction. From 2018 through 2025, this provision allowed many eligible practitioners to deduct up to 20% of their qualified business income from their taxes.

With the QBI deduction gone as of January 1, 2026, physicians are now taxed on 100% of their business income at the reverted, higher individual rates. This represents a double impact: a loss of a significant deduction combined with an increase in the percentage of tax paid on the remaining income.

Tax professionals cited by Medscape suggest that physicians who previously relied on QBI to lower their effective tax rate must now look toward aggressive retirement contributions or business expense acceleration to find similar relief.

What retirement strategies can lower taxable income for 2027?

Accountants recommend that physicians maximize “above-the-line” deductions to lower their adjusted gross income (AGI). Since the QBI deduction is no longer available, defined benefit plans have become a primary tool for high-earning doctors.

Unlike a standard 401(k) or 403(b), which has strict annual contribution limits, a defined benefit plan allows for much larger, age-based contributions that are tax-deductible for the business. This can significantly reduce the taxable income of a physician-owner during high-earning years.

Other recommended strategies include:

• Increasing contributions to Simplified Employee Pension (SEP) IRAs.
• Implementing “cash balance plans” to supplement traditional 401(k) contributions.
• Maximizing Health Savings Account (HSA) contributions for those with high-deductible health plans.

How should physicians approach business structures and estate planning?

The post-TCJA environment may make certain business structures less advantageous than they were between 2018 and 2025. Accountants suggest reviewing whether an S-corporation or a partnership remains the most tax-efficient vehicle given the current rate structure.

Beyond annual income taxes, the TCJA’s estate tax exemption is also scheduled to sunset. The exemption amount, which allowed individuals to pass significant assets to heirs tax-free, is expected to be roughly halved starting in 2026.

According to financial planning standards, physicians with estates exceeding the new, lower threshold should consider gifting assets or establishing irrevocable trusts now to avoid the 40% federal estate tax on assets that would have been exempt under the TCJA.

This shift creates a contrast between the 2018-2025 period, where estate planning was less urgent for many mid-to-high-net-worth physicians, and the current environment, where proactive asset transfer is necessary to prevent significant tax erosion of an estate.
