Below are seven proven ways to reduce your tax liability and keep more of what you earn.

1. Choose the Right Cardiologist Business Entity

If you own or co-own a cardiology practice, your business structure can significantly impact your tax preparation and tax liability. Here's how:

• S-Corporation: Allows you to split income between salary and distributions, potentially reducing self-employment tax.

• LLC: Offers flexibility and protection, but may not provide the same tax savings unless structured correctly.

• C-Corporation: Typically used in larger medical groups. Be cautious of double taxation unless other benefits outweigh the cost.

Pro Tip: It's important to keep up to date with tax preparation. Review your entity structure each year with a physician-focused tax advisor to ensure it still aligns with your income and practice goals.

2. Maximize Cardiology Retirement Contributions

Cardiologists can dramatically lower their taxable income by contributing to tax-advantaged retirement plans. Here are a few options to consider:

• Solo 401(k): Ideal for cardiologists with 1099 income or solo practices. You can contribute up to $69,000 in 2025 if you’re over 50, combining employee and employer contributions.

• Defined Benefit Plan: This is a powerful tool for older cardiologists with high incomes. Depending on your age and income, you may be able to contribute well over $100,000 annually — all tax-deductible. It also helps accelerate retirement savings later in your career.

• SEP IRA: Another option for self-employed cardiologists. You can contribute up to 25% of your compensation, up to $66,000 in 2025. It's simpler to set up than a Solo 401(k), but offers less flexibility.

Even if you're employed at a hospital or group, you can still consider strategies like the Backdoor Roth IRA to diversify your retirement savings and gain tax-free growth in the future.

3. Don’t Miss Deductible Expenses

If you have 1099 income, own a practice, or operate as an S-Corp, there are several legitimate deductions that can reduce your taxable income:

• Continuing medical education (CME)

• Board certification and licensing fees

• Malpractice insurance premiums

• Medical equipment and supplies

• Administrative use of your home office

• Business use of your vehicle

• Professional memberships and subscriptions

Use a cloud-based bookkeeping tool to categorize and track expenses throughout the year to ensure compliance and audit protection.

4. Consider Private Banking Strategies for Cardiologists

Many high-earning cardiologists are using private banking (also known as infinite banking) to create tax-efficient financial ecosystems. A few planning options can include:

• Use whole life insurance policies with cash value as a personal lending tool

• Build liquidity while preserving investment gains

• Borrow against yourself without triggering a taxable event

• Redirect taxable savings into self-financing strategies

While this approach isn’t right for everyone, when executed correctly with professional guidance, it can offer long-term tax advantages and financial flexibility.

5. Quarterly Tax Planning Is Essential

Waiting until April to think about taxes can cost you. Meet with your tax advisor every quarter to:

• Project your estimated tax liability

• Adjust your quarterly estimated payments

• Time major expenses or income distributions

• Implement last-minute tax-saving strategies like charitable giving or equipment purchases

Ongoing planning ensures you’re not only compliant but also maximizing opportunities throughout the year.

6. Work With Advisors Who Specialize in Physicians

Most CPAs aren’t equipped to handle the unique financial challenges of cardiologists.

Choose advisors who:

• Specialize in physician tax strategy and wealth management

• Understand the business models common in cardiology

• Can coordinate with your legal and financial planning teams

This team-based approach ensures all elements of your financial life are working together to minimize tax and build wealth.

7. Get Proactive About Exit Planning for Cardiologists

If you plan to retire or sell your practice in the next 5 to 10 years, it’s never too early to start planning.

• Assess the current value of your practice and how it impacts your net worth

• Explore capital gains tax strategies

• Consider trust structures or gifting options for generational transfer

• Reinvest tax-efficiently in preparation for life after medicine

The earlier you plan, the more control you’ll have over how much you keep when it’s time to step away.
