In an unprecedented move to funnel more public tax dollars toward groups that oppose abortion, Republican lawmakers in Missouri are advancing a plan to allow residents to donate to pregnancy resource centers instead of paying any state income taxes.

The proposal would establish a 100% tax credit, up from 70%, and a $50,000 annual cap per taxpayer. The result: Nearly all Missouri households — except those with the highest incomes — could fully satisfy their state tax bill by redirecting their payment from the state to pregnancy centers.

The move comes four months after Missouri voters reversed one of the nation’s strictest abortion bans, and just as clinics have begun performing the procedure again after overcoming Republican obstacles.
