Labor will have to find an extra $20 billion in funding after a leaked federal budget document showed a shortfall in the opposition's expected revenue from taxing smokers.
In a document obtained by the Nine Network, Treasury forecasts the tobacco excise will raise $28.2 billion over 10 years.

That's $19.8 billion less than Labor had predicted over the decade, leaving it short on funding for its spending promises - including fully funding the Gonski school model.
Labor frontbencher Anthony Albanese dismissed the leak, saying it didn't show what the government's policy on the tobacco tax actually was.
Often what the government spins was different to reality, he said, and Labor would wait to see the detail.
"I've learnt not to trust government spin, let alone a drop," he told Sky News.

Morrison set to announce company tax cut in budget
The federal government will fund company tax cuts through a crackdown on multinational tax dodging.
Treasurer Scott Morrison has told The Australian his "enterprise tax plan" will channel increased revenue into tax relief aimed at supporting the non-resources sector.
He says the tax office now has enough information about the structures of major multinational companies to estimate the additional tax revenue.
Mr Morrison has also flagged modest tax relief for people earning more than $80,000.
But it's unlikely there will be tax cuts for those on lower income brackets.
"People shouldn't expect measures to produce a next day better off/worse off comparison," he told Fairfax Media.

Cabinet minister Simon Birmingham says the government wants to help middle Australians who want to earn a few extra dollars but are facing disincentives because of tax brackets.
Lower income families already have a high tax-free threshold when family tax benefits and other measures are taken into account, and welfare payments are indexed, he told Sky News.
