<h1>Service tax changes: air travel caps limited, construction abatement raised and specific housing and skill-course exemptions introduced.</h1> Service tax measures cap the effective levy on passenger air travel and exempt domestic North-Eastern travel; construction-sector relief increases the abatement rate from 67% to 75% where gross value includes land and simplifies completion-certificate procedures; exemptions are provided for low-cost urban housing construction effective from a notified date after enactment; modular skill-development courses under the government skill initiative are exempted with immediate effect.
