Donald Trump has a history of tweeting about taxes.

He's used the topic to try to ridicule others and mock the process of filing taxes. But now, Trump's taxes have been thrust into the center of the presidential campaign following a Saturday New York Times story about the GOP nominee declaring a loss of $916 million on his income tax returns for 1995, a shortfall he could have used to avoid paying any federal income taxes for up to 18 years.

And so, the fiscal fighting words Trump has posted on social media are under a renewed spotlight, as Twitter users have re-posted some of them in the wake of the Times story.

There was the time in 2012 when he claimed tax day was President Obama's "favorite day of the year."

Yesterday was @BarackObama's favorite day of the year--he collects our taxes to redistribute. — Donald J. Trump (@realDonaldTrump) April 18, 2012

And when he said in all caps that "HALF" of Americans "don't pay income tax despite crippling govt debt."

In a 2011 Fox News TV interview that Mother Jones flagged Sunday, Trump said: "I don’t mind sacrificing for the country to be honest with you. But you know, you do have a problem because half of the people don't pay any tax."

He once posed next to a tall stack of papers and called signing his tax return "ridiculous."

Trump once argued that Obama's calls for wealthy Americans to pay more taxes were at odds with what he was paying.

@BarackObama who wants to raise all our taxes, only pays 20.5% on $790k salary. http://t.co/bqF26mQf Do as I say not as I do. — Donald J. Trump (@realDonaldTrump) April 13, 2012

And he said higher taxes meant he could employ fewer people.

To the geniuses at 'Americans United for Change': the more you tax me the less people I employ. Get it? — Donald J. Trump (@realDonaldTrump) August 7, 2012

Trump also said those managing hedge funds ought to pay more.

The hedge fund guys (gals) have to pay higher taxes ASAP. They are paying practically nothing. We must reduce taxes for the middle class! — Donald J. Trump (@realDonaldTrump) September 5, 2015
