The Manitoba New Democrats are reiterating their promise to give low- and middle-income families a tax break if they're re-elected on April 19 by taxing high-income earners.

NDP Leader Greg Selinger made the announcement at a home on Jefferson Avenue in Winnipeg on Friday morning, saying that a re-elected NDP government would fund the tax break by introducing a new income tax bracket for the wealthiest Manitobans.

The high-end tax bracket was previously announced in a non-binding fiscal update tabled by the NDP on March 8. It would apply to incomes over $170,000, Selinger said at the time.

The 20 per cent tax rate would affect 13,000 people (1.9 per cent of Manitobans) and create almost $50 million in savings for low-income and middle-income people, according to the party.

Selinger said the NDP, if re-elected, would also boost the Seniors' School Tax Rebate from $470 to $2,300 for the 2016 property year.

That would mean all but the wealthiest two per cent of Manitoba seniors would not have to pay school taxes, according to the party.

In last year's budget, the NDP government had doubled the rebate from $235 to $470 for the 2015 property tax year.
