Healthcare's fiscal trajectory belongs in every decumulation model

The federal government forgoes more than $500 billion a year on healthcare tax preferences, a Treasury tally the Tax Foundation cites in a new analysis, and the largest single item in that stack, per Treasury and the Joint Committee on Taxation, is the exclusion for employer-sponsored health insurance. Advisors building decumulation plans typically treat health care as a spending line with an inflation rate attached, but the Tax Foundation's numbers argue for something closer to a policy exposure with a term structure, since the client's health ledger is being priced on both sides at once: what care costs, and how Washington subsidizes or taxes it.

Scale is what makes the lens worth borrowing: total federal health spending and healthcare tax expenditures came to nearly $2.7 trillion in 2025, or 8.9 percent of GDP, a line the Tax Foundation projects will keep growing faster than the overall economy. Medicare, Medicaid, ACA subsidies and CHIP together form what the analysis calls the largest and fastest-growing category of federal spending, and federal healthcare spending in total is now nearly one-third of the budget, with the sector the most heavily tax-favored in the economy.

Little of that lands on a client's balance sheet tomorrow. The trajectory is what advisors should price, and the Congressional Budget Office figures assembled in the analysis are the reason: under current law, deficits rise from 5.8 percent of GDP in 2026 to 6.7 percent in 2036 and 9.1 percent by 2056, which the Tax Foundation describes as the largest sustained deficits in the country's history. Debt held by the public tops 100 percent of GDP in 2026 and reaches a projected record of 106 percent within four years, then 120 percent by 2036 and 175 percent by 2056. Spending climbs from 23.3 percent of GDP to 24.4 percent and then 27.9 percent against a 50-year average of 21.1 percent, while revenues move only from 17.5 percent to 17.8 percent and 18.8 percent, so revenues are not closing that gap and the arithmetic has to give somewhere. The Tax Foundation's case is that healthcare policy is where it gives, though whether that means higher premiums, slimmer subsidies, a narrower exclusion for employer coverage or some combination is speculation rather than forecast.

The planning problem arrives long before the political one. A decumulation model that pins Medicare premiums, supplemental coverage and long-term care costs to a single inflation figure is quoting a point estimate on a line that has outrun GDP for years, and it is simultaneously assuming the current tax treatment of employer-sourced benefits survives intact. The sharper practice builds the stress case the way it builds a bad-market case: what happens to the same retirement income if health costs run above trend, and what happens to after-tax value if the exclusion narrows. As this publication has argued, the last mile is an income, health-cost and benefit-claiming problem, and the advisors who keep the Boomer relationship will be the ones who put a rule-change scenario in the plan before the client asks for one.

Sequencing rewards preparation here. The 2027 opportunity-zone deferral gave advisors a window to model the exit before the entry was sold, and this publication made the same argument about the mechanics of the federal retirement savings match: new rules are cheapest to absorb while the client still has room to react, not after a premium notice forces the conversation. The Tax Foundation's conclusion is that healthcare reform is now essential to a sustainable fiscal path, and until one arrives the $2.7 trillion line keeps compounding against the same client income—which is the argument for pricing it in the plan now rather than after the next CBO update.
