Donald Trump will propose new federal subsidies for child care, including tax deductions, rebates for lower-income households that do not itemize expenses, and a dependent-care savings accounts Tuesday night in a Delaware County appearance, campaign officials said.

Daughter Ivanka Trump, who helped develop the policy ideas, will accompany her father and introduce him at the 7:30 p.m. event at the Aston Community Center in Aston, Pa. The location is politically significant, as polls show Donald Trump has struggled to reach women and swing voters in areas such as the Philadelphia suburbs.

Under the plan, taxpayers will be able to deduct the average annual cost of child care in their state on federal income taxes. The benefit would apply to individual taxpayers making up to $250,000 and joint filers making up to $500,000, the campaign said in a morning preview briefing for reporters.

For those with no income-tax liability, the Earned Income Tax Credit would be expanded to give a cash rebate of up to half the filer's Social Security payroll tax.

Trump also will call for providing six weeks of paid maternity leave through the unemployment insurance system for women whose employers do not offer paid leave on their own. The campaign believes that this will help with the disparity in wages between men and women in the workplace, aides said.

The plan also includes a new tax-advantaged savings account that would allow people to save money for the care of children and elderly relatives. It would be more widely available and less restrictive than the flexible savings accounts (FSA) offered by employers, said a campaign aide who outlines the proposals.

The aide could not say how much tax revenue would be lost to the new breaks, but added the proposals would fit into Trump's overall tax and economic policies, which will be detailed more fully in coming days.
