A leading business group is hopeful that tax benefits aimed at small firms and tied to Labor's mining tax will be retained in the May budget.
Under the coalition's repeal of the minerals resource rent tax (MRRT), measures the impost were supposed to fund will go.
Those to be ditched include a loss carry-back initiative, which allows business to offset losses to get a refund on previous tax paid, while returning the instant asset write-off for small business to $1000 from $6500.
But a Senate inquiry report into the repeal legislation supported revisiting taxation issues affecting small business "once the budget returns to strong surplus".
Australian Chamber of Commerce and Industry chief executive Peter Anderson said he had warned the previous government that linking small business tax measures to a badly-designed mining tax could short change small business.
"Decoupling small business tax relief from the mining tax, and funding it via efficiency savings in next year's federal budget following the commission of audit, would be the right policy approach," Mr Anderson said in a statement.
The chamber supports the MRRT repeal and delaying increases in the superannuation compulsory guarantee for two years as part of the package.
The Senate committee also recommended the low income super contribution that faces the axe should be revisited as part of the government's promised tax review.
Anglicare Australia executive director Kasy Chambers said each measure in the MRRT package should be assessed on its own merit as their abolition will have a devastating effect on Australia's poorest households.
"These are very important measures for those on the lowest incomes, the majority of whom are women who should be encouraged to save for retirement, and those receiving government payments," she said.
