New Jersey's gas tax goes up Monday (and so do other taxes). Here's what you need to know.

They'll be a bit more pain at the pump beginning Monday, New Jersey.

Taxes on gasoline sold in New Jersey will rise 4.3 cents per gallon on Monday, a hike triggered by a slowdown in how much gas we're buying.  

The increase was met with anger from taxpayers still reeling from the 23-cent-per-gallon increase in 2016. But tax collections have fallen short the past two years, precipitating the Murphy administration's announcement last month that it was raising the tax again.

And that's not all. A few other taxes are also on the rise. 

Here's all you need to know about Jersey's gas tax, and what else is going up. 

If the gas tax just increased in 2016, why is it going up again?

In the fall of 2016, Gov. Chris Christie and the Democratic-controlled Legislature agreed to raise the motor fuels tax 23 cents a gallon to fund road and rail projects in New Jersey.  

But because that revenue is dependent on how much gas people buy, they also wanted assurances that they would have enough money to pay for those projects.

They agreed that a three-person committee should review the tax's performance each year to determine if it's bringing in enough, too much, or not enough money to pay the bills.

If gas sales are booming and gas tax dollars are flowing into state coffers, then the treasurer could reduce the tax. If sales are slowing and it's not generating enough money, the treasurer could raise the tax.

That's what has happened here.

Revenues fell $125 million short of the $2 billion target in the fiscal year that ended in June and $43 million short the year before.

Murphy's administration announced it needed another 4.3 cents per gallon for the gasoline and diesel fuel taxes to hit their target.

The two tax hikes come after New Jersey enjoyed a long period without any increases. Prior to the 2016 increase, the gas tax had not been increased since 1988.

Is it still cheaper than New York and Pennsylvania?

Indeed.

At 58.7 cents per gallon, Pennsylvania has the highest state taxes on gasoline in the U.S. 

New York isn't far behind, clocking in with the fifth-highest gas tax at 45.76 cents per gallon.

After this latest increase, New Jersey's will be 41.4 cents per gallon.

How will New Jersey rank nationally?

While New Jersey's gas tax will still be lower than New York and Pennsylvania, it will be higher than 41 other states.

Besides those neighbors, the gas tax here would be lower only than Indiana, Connecticut, Michigan, Hawaii, Washington and California. Nj.com
