A plan to raise taxes on the wealthy is emerging as the leading option among House Democrats looking to finance health care legislation that President Obama wants.

Numerous officials say that under the proposal, an income tax surcharge would be imposed on individuals earning more than $200,000, with a higher threshold for couples.

The same officials say earlier options under consideration have been abandoned. Among them was a proposal to raise the payroll tax that finances Medicare. The officials spoke anonymously to discuss private discussions.

House Democrats hope to unveil legislation on Friday that reins in the overall growth of health care spending, at the same time it extends coverage to millions who lack insurance.
