It's a deceptively simple problem: Match how much money state government takes in with how much it spends.

But the devil, as the saying goes, is in the details. And if there's one thing California government abounds in, it's devilish details: more than 150 agencies and departments populated by more than 200,000 employees carrying out uncounted programs that serve more than 37 million people.

If you want to pay for all those programs, you have to raise more revenue than the state has now, or is likely to have. Conversely, if you don't want to raise revenue, you have to cut into or abolish many of those programs.

Simple, at least to define. To solve it, however, is a lot more complex.

Depending on whose numbers you use, California is facing a budget deficit of from $24.2 billion to $27.8 billion over the next 19 months.

To close the gap, legislators and Gov. Arnold Schwarzenegger are mulling over – and arguing about – a host of possible ways to increase revenue and cut spending.

Here, in nutshell form, are just some of the possibilities and their potential effects.

CUTTING SPENDING

Schwarzenegger has proposed $4.5 billion worth of spending cuts in the current budget. About $3.8 billion of it is in these four areas:

SCHOOLS

The governor wants to cut about $2.2 billion from elementary and high schools (about 4.2 percent of their total budget) and about $300 million from community colleges (5.2 percent of their budget). Schwarzenegger also proposes to relax some state regulations to give local districts more flexibility in making the cuts.

But school officials say it would be nearly impossible to make that deep a cut midway through the school year, because districts already have signed contracts, set staff levels and class size, and started programs.

The Legislative Analyst's Office recommends that the cuts be reduced to $1 billion by rescinding a small cost-of-living increase for K-12, raising community college per-unit fees from $20 to $26, deferring some maintenance and delaying the purchase of some instructional materials.

SOCIAL SERVICES

The governor proposes to cut state grants to the elderly, blind and disabled from $870 a month to $830 a month for individuals. He also would reduce grants and eligibility for welfare, and would restrict access to services for shut-ins. That would save $783 million.

The legislative analyst recommends a less drastic package of about $250 million in cuts.

STATE PAYROLL

Rather than laying off state workers, Schwarzenegger wants to furlough workers one day a month and take away two of their 13 fixed holidays. That would amount to a 4.6 percent pay cut and save the state $320 million.

The legislative analyst has no recommendation to counter Schwarzenegger's. But state workers have protested that it's unfair that they would be subject to any tax hikes that are approved and have their salaries cut.

LOCAL MASS TRANSIT

The governor proposes cutting state assistance to local mass transit programs by $230 million. The Legislative Analyst's Office suggests grabbing revenue not being used by the Department of Motor Vehicles ($55 million) and redirecting some funds paid by Indian casinos for transportation purposes to the state's general fund ($62.9 million).

Local transit officials point out that the budget already diverts $1.7 billion from the state's Public Transportation Account to pay for other programs.

RAISING REVENUE

INCREASE SALES TAX

The governor has proposed raising the state's general sales tax rate of 7.25 percent to 8.75 percent for three years. (That doesn't include local governments' additions, which already bring the total to as much as 9.25 percent in some parts of the state.)

The boost would increase state revenue by an estimated $10.9 billion over the next 18 months – and would add $375 to the price of a $25,000 car.

California has the highest base sales tax rate of any state, according to the Federation of Tax Administrators, and Californians spent $1,039 per capita in 2005 on state and local sales taxes, according to the National Conference of State Legislatures. That's 13th among 50 states. The sales tax was last increased in 1991, by 1.25 percent.
