(MSC News)--Democratic Governor Laura Kelly Thursday vetoed the third Kansas tax plan sent to her desk this year.

Kelly says the bipartisan effort still costs the state too much and is not sustainable.

The vetoed plan would have slashed Kansas revenue roughly $470 million each year through income, Social Security and property tax cuts. The governor says the bill needs to be less than her $425 million limit because of other tax bills lawmakers have already passed.

Kelly says she will announce next week the date for a special legislative session to hammer out a compromise on taxes.
