Assuring Medicare’s Promise Act of 2025
Summary
What This Bill Does
The Assuring Medicare's Promise Act of 2025 changes how the net investment income tax supports Medicare and broadens the income base for high-income taxpayers. Section 2 directs receipts from the Internal Revenue Code section 1411 net investment income tax into the Federal Hospital Insurance Trust Fund for taxable years beginning after December 31, 2025. Section 3 expands the tax for certain high-income individuals by adding specified trade or business income, with thresholds of $400,000 for most taxpayers, $500,000 for joint returns and surviving spouses, and half the otherwise applicable threshold for married individuals filing separately. The bill includes a phase-in formula over a $100,000 range, excludes income already subject to Medicare payroll or self-employment taxes, covers certain foreign-employer wages, and directs Treasury to issue regulations for implementation.
Who Benefits and How
The Medicare Hospital Insurance Trust Fund benefits because net investment income tax receipts are deposited into the trust fund. Medicare beneficiaries benefit indirectly if the trust fund receives a dedicated revenue stream tied to high-income investment and business income. Workers paying Medicare payroll taxes benefit from a financing rule that applies comparable Medicare financing to high-income investment and business income. Treasury tax administrators benefit from explicit statutory thresholds, exclusions, and regulatory authority for the expanded tax base.
Who Bears the Burden and How
High-income taxpayers with specified trade or business income may owe additional section 1411 tax. High-income pass-through business owners must evaluate the new threshold, phase-in, and exclusion rules. Treasury and IRS staff must issue regulations, update forms, and administer deposits into the Hospital Insurance Trust Fund. Tax advisers and return preparers must apply the new income calculations, foreign-employer wage rules, and Medicare-tax exclusions.
