RALEIGH, N.C. (AP) — A Republican plan to cut jobless payments and raise business taxes to speed repayment of North Carolina's $2.5 billion federal debt on unemployment benefits won tentative approval Tuesday in the state Senate, all but ensuring enactment this summer.

Four Democrats joined GOP senators in voting 36-13 for the House measure, which would cut maximum weekly benefits for new jobless workers July 1 by one-third and reduce the maximum duration of state benefits from 26 weeks to 20.

Businesses both large and small would keep paying higher federal taxes until the debt to the federal government is repaid. Under the accelerated plan, that would probably now be late 2015, instead of three years later if no changes to state law were made. State taxes would go up slightly on a permanent basis, while a surcharge would remain in place until there's a $1 billion cushion in the state trust fund to pay future benefits.
