The architects of the Affordable Care Act thought they had a blunt instrument to force people — even young and healthy ones — to buy insurance through the law’s online marketplaces: a tax penalty for those who remain uninsured.

It has not worked all that well, and that is at least partly to blame for soaring premiums next year on some of the health law’s insurance exchanges.

The full weight of the penalty will not be felt until April, when those who have avoided buying insurance will face penalties of around $700 a person or more. But even then that might not be enough: For the young and healthy who are badly needed to make the exchanges work, it is sometimes cheaper to pay the Internal Revenue Service than an insurance company charging large premiums, with huge deductibles.

“In my experience, the penalty has not been large enough to motivate people to sign up for insurance,” said Christine Speidel, a tax lawyer at Vermont Legal Aid.

Some people do sign up, especially those with low incomes who receive the most generous subsidies, Ms. Speidel said. But others, she said, find that they cannot afford insurance, even with subsidies, so “they grudgingly take the penalty.”
