Historical evidence shows revenues rose after early-2000s tax cuts; FY2002 decline driven by economic shock, not policy
Boston, MA — As Massachusetts considers a ballot initiative to reduce the personal income tax rate from 5 percent to 4 percent in three equal steps beginning in 2027, a new analysis finds that the Commonwealth’s last major income tax rollback did not produce sustained revenue loss, and that the one significant year of nominal decline, FY2002, was driven by economic shock, not tax policy.
The report, Lessons from the 2000 Massachusetts Income Tax Rollback: Expanded Analysis to Inform the 2026 Ballot Debate, examines fiscal and economic data from 1998 through 2021 and isolates the effects of each rate change.
Massachusetts reduced the personal income tax rate incrementally in 2000 and 2002 by a total of 0.35 percent, which led to a cumulative revenue increase from $8.0 billion to $9.9 billion (nearly $2 billion, or +24.0 percent).
- In FY2000, the Legislature reduced the rate from 5.95 to 5.85 percent (-0.10 percent) and saw revenues rise from $8.0 billion to $9.0 billion (+12 percent);
- In FY2001, when the 2000 ballot initiative’s first rate cut to 5.6 percent (-0.25 percent) helped revenues grow to $9.9 billion (+10 percent).
“Tax cut opponents always skip all the years of revenue growth on either side fiscal year 2002, a terrible year for the U.S. that included the dotcom bust and the economic aftermath of 9/11,” said Jim Stergios, Executive Director of Pioneer Institute. “The evidence is that sequential and modest reductions do not produce the level of revenue losses critics claim.”
The FY2002 decline was driven by economic contraction, not the rate cut
The third consecutive rate reduction (from 5.6 percent to 5.3 percent) took effect in January 2002. In FY2002, which spanned the dot-com bust and the economic fallout after September 11, revenues declined to $7.9 billion, a drop of approximately $2.0 billion (-20.0 percent).
The analysis isolates the effect of the rate change by holding the FY2001 tax base constant; the 0.3 percentage-point reduction would have reduced revenues by approximately $530 million. The remaining $1.5 billion of the decline was driven by a roughly 70 percent collapse in capital gains proceeds.
By FY2000, capital gains revenues had reached approximately $1.164 billion and accounted for a disproportionate share of personal income tax growth in the late 1990s. When those realizations collapsed, revenues followed.
“The FY2002 decline is not evidence against tax reductions,” said Stergios. “The loss was driven by a national collapse in capital gains and a broad economic contraction. States that did not cut taxes experienced similar or larger declines.”
In FY2003, the Legislature froze the rollback and raised the capital gains tax rate
Lawmakers responded to the FY2002 revenue crisis by freezing the scheduled final step of the 2000 ballot initiative and repealing the prior sliding scale treatment of long-term capital gains, instead taxing those gains at 5.3 percent beginning in January 2003. Under the earlier structure, assets were taxed based on holding period, with rates declining over time.
That policy shift is central to understanding what followed. The Legislature attributed the shortfall primarily to the income tax cut and responded by both halting the rollback and restructuring the taxation of capital gains. Because the prior system taxed gains at different rates depending on holding period—ranging from 0 percent to 6 percent—calculating a single effective pre-2003 rate is conjecture. The Institute has submitted a public information request to the Massachusetts Department of Revenue to obtain additional capital gains realizations by holding period.
After FY2003 revenues stabilized and grew with the economy
With the 5.3 percent rate in place for a full fiscal year, revenues stabilized in FY2003 and then increased steadily through FY2008, rising from $8.8 billion to $12.5 billion, a 42 percent increase over four years. In inflation-adjusted terms, revenues at the lower personal income tax rate exceeded prior peaks within several years. By FY2008, Massachusetts was collecting approximately $18.7 billion in personal income tax revenue in 2025 dollars, surpassing the $15.5 billion in collections in FY1999 before any cut was applied.
During the Great Recession (2008-2010), Massachusetts and all U.S. states experienced significant revenue declines. Emerging from that downturn, the pattern of revenue growth seen from FY2000 reasserted itself from 2012 to 2020, when six trigger-based reductions tied to revenue growth thresholds lowered both the income tax and capital gains rates from 5.3 percent to 5.0 percent. In every trigger year except FY2016, nominal revenues were flat or higher year over year, and over the full 2012–2021 period real personal income tax revenues rose by roughly 40 percent, even as capital gains realizations and total revenues increased.
In FY2020, the year the rate reached 5.0 percent, revenues held steady despite the COVID-19 recession (effectively a real-time stress test of the lower rate) and in FY2021 revenues increased by 13 percent.
“Some critics fixate on FY2002 (the year of the dot-com collapse and September 11) and treat it as proof that tax cuts cause revenue declines,” added Stergios. “The full record shows the opposite: revenues track economic conditions, not tax rates.”
