Tax Planning for Cardiologists (2026)

Many cardiologists have moved from private groups to hospital employment, and others hold interests in cath lab joint ventures or outpatient imaging. Planning depends on which model you are in.

Tax planning priorities for cardiologists

Hospital employment

Employed cardiologists usually have a 403(b) and often a 457(b); using both and a backdoor Roth is the starting point.

Joint ventures

Interests in cath labs or imaging centers produce K-1 income that may be subject to the net investment income tax if passive.

Practice owners

Independent cardiology groups can combine 401(k), profit-sharing and cash balance plans and elect the state PTET.

Late career

Cardiologists who plan to reduce call or retire early benefit from Roth conversion planning in lower-income years.

Strategies that apply to every specialty

• Know your marginal rate. In 2026 the 37% federal bracket starts at $640,600 (single) and $768,700 (joint); see how much tax doctors pay.
• Fill every tax-advantaged account: 401(k)/403(b) ($24,500 in 2026), 457(b), HSA and a backdoor Roth.
• Match the plan to how you are paid: W-2, 1099 or practice owner.
• Use your state's rules; see our 50-state guides.
