Rising federal debt in the United States could translate into significant financial pressure for households, with new analysis pointing to substantial tax increases across income groups. The findings highlight the scale of adjustment required to stabilise public finances over the coming decade.
The issue has received limited political attention, yet the figures outlined by researchers suggest that narrowing the gap between spending and revenue would require measures far beyond targeted tax changes. According to theBrookings Institution, the burden would likely extend well beyond higher earners.
Broad-Based Tax Increases Emerge as Primary Solution
The analysis, prepared by Brookings fellow Jessica Riedl, examines how the United States could stabilise its debt-to-GDP ratio at 100% by 2036. According to a recent report by Fortune, achieving that target would require generating an additional $2.6 trillion in revenue beyond current projections from the Congressional Budget Office.
Several policy options are assessed, including proposals focused on high earners and wealth. According to the Brookings study, measures such as a 77% estate tax combined with an 8% wealth tax would close only18% of the fiscal gap. Similarly, raising the top income tax rate to 50% for higher-income households would cover roughly one third of the shortfall.
Instead, the report identifies three broad-based approaches capable of fully addressing the gap. One option would involve increasing all income tax brackets by 12 percentage points. Another would raise payroll taxes by 11.5 percentage points while removing the income cap applied to Social Security contributions. A third approach would introduce a value added tax of around 30%, a system widely used across other OECD economies.
According to the analysis, each of these options draws from a large tax base, which is why they generate sufficient revenue. The findings suggest that narrower measures targeting specific groups are insufficient given the scale of the deficit.
Estimated Household Impact Reaches $18,000 Annually
The implications for households are significant. According to Brookings, by 2036 the United States is projected to have approximately144 million households with an average income of $119,000, assuming steady annual growth.
Under the scenarios outlined, each of the three main tax approaches would impose a similar burden. The study estimates that households would need to contribute an additional $18,000 per year on average. This represents roughly 15% of income, affecting spending capacity across everyday expenses.
The report also places current debt levels in context. According to the data presented, federal debt per household already stands at around$235,000, a figure described as comparable to an additional mortgage obligation. At the same time, the United States is running some of the largest budget deficits among OECD countries.
Riedl notes in the study that stabilising debt at 100% of GDP would still leave the country with historically high borrowing levels and significant interest costs. These costs already rival spending on major programmes such as Medicare, underscoring the long-term fiscal pressure.
While a combination of tax increases and spending reductions is theoretically possible, the report indicates that the most effective solutions share a common feature: they apply broadly across the population. According to Brookings, this reflects the scale of the fiscal imbalance rather than a specific policy preference.
