The Public Health and Welfare Committee approved the bill Friday after a brief hearing. Legislators made no changes to the bill, which cleared the House earlier this week.
It's the most sweeping anti-abortion bill being pursued in Kansas this year.
The measure bars groups providing abortions from receiving tax exemptions or credits that go to other nonprofit groups or health care providers. It would also prohibit women who claim income tax deductions for medical expenses from including the cost of abortion services.
The legislation also prohibits abortion providers from furnishing materials or instructors for sex education classes in public schools.
