The health of the Medicare trust funds has worsened over the last year while prospects for Social Security’s remain the same, trustees for the programs said in their annual reports released Wednesday.

The Medicare funds are now expected to become insolvent in 2028, two years earlier than the trustees estimated in 2015.

For Social Security, its trustees continue to estimate the Old Age and Survivors Insurance and Disability Insurance Trust funds will be depleted in 2034. After then, benefits would have to be reduced 21 percent if employee and employer taxes remained at current levels.

While there are years before the problems for both programs become immediate, Congress should fix the funding woes to aid the economic security of seniors, Treasury Secretary Jack Lew said at a briefing on the report. Lew is the managing trustee for the funds of both Social Security and Medicare.

He said Social Security benefits should be increased for the most vulnerable.

Medicare trustees called for funding fixes from Congress “sooner rather than later” to minimize the impact of shortfalls on beneficiaries, providers and taxpayers.

The funds for Medicare supplemental insurance, which pays for doctor bills, other outpatient expenses and drugs, are expected to remain solvent indefinitely because the law allows for taxpayer funding and premium increases.

For Social Security to remain solvent for 75 years, the trustees said benefits would have to be cut for current and future beneficiaries by 16 percent, or 19 percent for beneficiaries who become eligible for payments this year and after. Payroll tax increases of 2.58 percent to 14.98 percent would be another option for solvency.

The trustees called upon Congress to increase Social Security taxes and reduce benefits quickly rather than years later to spread the burden to all generations.

Looking at Social Security in the presidential campaign, Hillary Clinton’s website said she believes keeping the system solvent long term is only possible by raising payroll taxes on the highest-income earners, including some of their income above the current cap, and taxing some of their income not currently taken into account by the current rules.

She opposes aiding the long-term health of the programs by reducing annual cost-of-living adjustments, raising the retirement age, or middle-class Social Security benefit cuts and tax increases.

On other Social Security issues, Clinton said she wants to raise the amount of benefits a husband or wife receives after a spouse dies to prevent financial hardship and potential poverty.

She also advocates giving Americans credit toward their Social Security benefits when they are out of the paid workforce because they are acting as caregivers.

By contrast, Trump’s campaign website has nothing about Social Security.

In an April campaign ad and in other pronouncements, he said he would save Social Security without cuts.

Last year, Social Security had 60 million beneficiaries, with 55.3 million individuals receiving aid from Medicare.
