TOPEKA, Kan. (KAKE) - Many political experts were shocked Tuesday to see lawmakers pass the big Kansas tax cut nearly unanimously, saving taxpayers more than $1.2 billion over the next three years.

"One really nice piece of news is that it was bipartisan. The whole thing was bipartisan," said Emporia State University Political Science Professor Michael Smith.

The bill passed 34-4 in the Senate and 121-2 in the House, and Governor Laura Kelly has already pledged to sign it into law.

"This was really a big win for the governor, and it was a win for the legislators too," said Smith.

Here are some of the biggest changes for the average taxpayer.

The state will now only have the two following tax brackets, depending on income level:

5.2% tax
$0 - $46,000 for couples
$0 - $23,000 for individuals 

5.58% tax
$46,001+ and up for couples
$23,001 and up individuals

The standard deduction, which Smith says is what most people use, will increase from $3,500 to $3,605 for individuals and from $8,000 to $8,240 for couples.

Smith says the minimum amount of money you have to make before the state taxes you at all is increasing from just $2,250 for everyone, to $18,320 for couples and $9,160 for individuals.

Smith says translating all these numbers into exactly how much extra you'll have in your pocket isn't so easy.

"How many dependents do you have? You know, what's your income level? Are you married, filing jointly? Are you single," Smith explained.

However, he says it will certainly be a noticeable number for many residents.

"It's going to be particularly beneficial to the lower-income taxpayers. Some people may even find that they no longer owe any state taxes at all," said Smith.

Lawmakers say another huge benefit to the older age range is that all Social Security benefits will now be totally exempt from Kansas income tax.
