SACRAMENTO – Personal income tax revenues continued to surpass expectations in December, pushing the month’s total state collections $381.7 million, or 2.8 percent, higher than expected, State Controller Betty T. Yee reported Monday.

“It’s encouraging to see the state’s continued fiscal strength,” Yee said. “But as Gov. Brown stressed in his budget proposal last week, we need to be aware that the good times will not last forever. As the state’s chief fiscal officer, I will be closely monitoring revenues to detect signals of a downturn.”

Total revenues for December were $14.1 billion. Personal income tax for the month came in at $9.5 billion, $388.3 million more than expected when the budget was enacted last summer. Corporation tax revenues of $1.7 billion beat projections by $25.8 million, or 1.5 percent.

These gains were offset slightly by retail sales and use tax revenues of $2.4 billion, short of estimates by $35.8 million, or 1.5 percent.

For the first half of the fiscal year that began in July, total revenues of $51.1 billion exceeded projections by $884.6 million, or 1.8 percent, with higher-than-expected personal income tax revenues more than offsetting shortfalls in the corporation tax and the sales and use tax.

Personal income tax since the beginning of the fiscal year beat estimates by $1.3 billion, or 3.9 percent. The corporation tax fell short by $120.6 million, or 3.6 percent, while the sales and use tax slipped $262.5 million, or 2.1 percent, compared to projections.

The state ended the month of December with $11.1 billion in outstanding loans – $1.4 billion, or 11.4 percent, less than expected.

For the first year in 15 years, the state is covering month-to-month shortfalls exclusively through internal borrowing from special funds rather than external loans, such as revenue anticipation notes.

The improved fiscal condition of the General Fund, the source of most state spending, has saved the state tens of millions of dollars in interest costs.
