After a major health care reform failure on Friday, Republicans say they’re moving on to tax reform.

The party may try again to repeal and replace the Affordable Care Act (ACA), or Obamacare, although House Speaker Paul Ryan — speaking at a Capitol Hill news conference Tuesday — wouldn’t put a timeline on it.

One place some provisions of repeal and replace could spring up is tax reform, experts said.

“Irreconcilable fractures within the Republican party ultimately caused the demise of the AHCA, but that does not mean a much more stripped down version of ACA repeal couldn’t move alongside tax reform,” said a Height Securities note by analysts Andrew Parmentier and Stefanie Miller.

AHCA refers to the Republican bill, the American Health Care Act.

So what would the lite version of an ACA repeal look like? The health care law’s taxes—which apply to medical devicemakers, prescription drugmakers and high earners, among others, and total nearly $1 trillion—are likely to be targeted.

Tax reform could also target the ACA’s unpopular individual mandate, which requires Americans to obtain health coverage or pay a tax penalty.

The individual mandate is supposed to allow for coverage of those with pre-existing medical conditions by encouraging young and healthy people to also buy health insurance.

Republicans might try to replace the individual mandate with a “continuous coverage” requirement, said Height Securities’ Parmentier and Miller.

The requirement, which is outlined in AHCA, penalizes those who go at least two months without health insurance by making their health coverage 30% more expensive for the first year.

But repeal lite could—although it’s unlikely—target the ACA’s subsidies, which make exchange plans affordable to middle and low-income individuals, said Spencer Perlman, director of health-care research at Veda Partners.

The temptation there is clear: the AHCA was projected to decrease federal deficits by $337 billion over the next 10 years, according to a Congressional Budget Office estimate. By contrast, slashing tax rates would add to the deficit.

Of course, there’s no guarantee a tax bill would pass either.

“It can be argued that failure to execute on the repeal and replace of the ACA certainly adds a potential headwind to accomplishing broad tax reform, as hoped by the Street,” said Veda Partners’ Spencer Perlman and Sumesh Sood, adding “tax reform is difficult and is going to be a slog at best.”
