Republican presidential candidate Donald Trump has proposed imposing a temporary moratorium on new federal regulations, reviving the Obama-stalled Keystone oil pipeline project, slashing business tax rates and making childcare expenses fully tax-deductible, in a landmark economic speech Monday.

A campaign aide said Monday that 'we don't want it to be an economic disadvantage to have children.'

The childcare move was first teased by Ivanka Trump in her Republican convention speech when she said he would 'focus on making quality childcare affordable and accessible for all.'

Trump's other economic proposals include measures to dramatically reduce income tax rates and simplify taxes for all Americans. He said in a speech to the Detroit Economic Club that as president he would trim the number of personal tax brackets from seven to just three, and introduce a zero-tax band for the lowest earners.

He would also turn away from Hillary Clinton's approach, he said Monday – 'more of the same: more taxes, more regulations, more bureaucrats, more restrictions on American energy and American production.'

TRUMP'S PLAN AT A GLANCE FEDERAL INCOME TAX Currently: Seven tax brackets start at 10 per cent and go up to 39.6 per cent Under Trump: A zero tax band for the lowest earners, then bands of 12 per cent, 25 per cent and 33 per cent FEDERAL ESTATE TAX Currently: 40 per cent tax on all estates over $5.45 million for individuals and $10.9m for couples Under Trump: Abolished CHILD CARE Currently: Up to 35 per cent of childcare costs of $3,000 for one child or $6,000 for two ore more is tax deductible. Actual amount depends on parents' income Under Trump: 100 per cent of childcare costs tax deductible CORPORATION TAX Currently: Statutory rate of 35 per cent, effective rate can be as high as 39 per cent Under Trump: Effective rate of 15 per cent ENERGY Currently: Keystone XL pipeline is not going ahead, Climate Action Plan is centerpiece of energy policy. Under Trump: Keystone sponsors invited to apply again for permission, Climate Action Plan abolished Advertisement

Trump also proposed a repeal of the estate tax, which Republicans derisively call the 'death tax.'

That federal tax hits estates valued at over $5.45 million for individuals and $10.9 million for couples and take 40 per cent of their value.

A tax rate of 15 per cent would be the norm for businesses in a Trump administration, and hedge-fund managers would no longer get the benefit of special treatment for 'carried-interest.'

That tax, on investment earnings paid to fund managers, is currently taxed like capital gains – at rates far lower than ordinary income.

Current federal tax rates for business income top out at 39 per cent, a rate that Trump has correctly placed as among the highest in the world.

Trump focused mostly on trade, taxes, immigration and regulation. The club, whose members are area business leaders, is a traditional venue for political candidates to discuss their economic vision.

The Detroit speech was his first on the economy since announcing a 13-man team of economic advisers last week.

It also came after he slogged through perhaps his worst week as a candidate, getting entangled in a fight with the Muslim parents of an American soldier slain in Iraq in 2004 and sparring with Republican Party leaders.

Trump proposed stronger protections for American intellectual property and a temporary moratorium on new regulations.

Members of Trump's advisory group shared their views on policy with senior Trump aides on Sunday in a conference call, said banker Stephen Calk, one of the members who took part.

Calk described Trump's vision for taxes as the biggest tax revolution since President Ronald Reagan in 1986.

He said the plan was to lower the corporate tax burden and encourage U.S. companies with operations abroad to repatriate profits at a reduced tax rate.

The current corporate rate is 35 per cent; Republicans have long sought to reduce it.

Trump's rough ride last week, plus a boost in support for Democratic candidate Hillary Clinton after she accepted her party's nomination at its Philadelphia convention, has taken its toll on him.

A Washington Post-ABC News poll released on Sunday gave Clinton an eight-point lead, 50 per cent to 42 per cent. A Reuters-Ipsos poll from last week had her in the lead with a smaller margin of three points.

Trump contrasted his approach with that of Clinton, saying that 'if you were a foreign power looking to weaken America, you couldn't do better than Hillary Clinton's economic agenda.'

TRUMP'S PLAN TO PUT U.S. CORPORATION TAX ON A PAR WITH GERMANY...AND IRAQ The United States is well-known for having one of the world's highest headline rates of corporation tax, at 35 per cent - but it's not the only country to charge that much. However, if Trump slashes the tax rate to 15 per cent, that would put the nation on a par with countries including Germany, Iraq and Albania.

'Nothing would make our foreign adversaries happier than for our country to tax and regulate our companies and our jobs out of existence.'

'The one common feature of every Hillary Clinton idea,' he said, 'is that it punishes you for working and doing business in the United States. Every policy she has tilts the playing field towards other countries at our expense.'

Trump campaign chair Paul Manafort said in an interview with Fox Business Network on Sunday that Clinton is 'going to raise taxes, lots of taxes, on everyone,' making the 'recovery, which is already the weakest since 1949, even worse.'

'Starting Monday, we're going to be announcing our economic plan. When we do that, we're comfortable that we can get the agenda and the narrative of the campaign back on where it belongs, which is comparing the tepid economy under Obama and Clinton, versus the kind of growth economy that Mr. Trump wants to build,' he said.

Trump's Detroit event gave him a chance to regain the initiative and outline some substantive policy proposals on the economy ahead of the Nov. 8 election.

Larry Kudlow, an informal Trump adviser and CNBC commentator, wrote on CNBC.com that Trump will pledge to lower marginal tax rates on both large and small businesses and on all income classes. He also will propose an increase in the standard deduction for families and special deductions for childcare and the elderly, Kudlow said.

'All of these polices will help the middle class. Trump's plan will generate substantial new investment, business formation, jobs, and growth - and, hence, higher wages,' he wrote.

Trump has vowed to rewrite some international trade deals, including the North American Free Trade Agreement of 1994, a deal linking the economies of the United States, Mexico and Canada and signed into law by Clinton's husband, then-President Bill Clinton.

Critics blame NAFTA for encouraging the outsourcing of jobs that have taken away many middle-class employment opportunities.

Peter Navarro, a University of California-Irvine professor who is the only formal Trump economic adviser with a deep academic background, said one of the problems Detroit has seen from NAFTA has been a movement of auto manufacturing jobs to Mexico, citing Ford and GM recently.

Trump also said Monday that he would reduce federal regulations that he blames for stifling economic activity.
