Now that Clinton is releasing her most recent 2015 tax returns, and her VP Tim Kaine is releasing his last 10 years of returns, the media is focusing and speculating more and more about Trump's tax returns, and why he is not releasing them. Many tax experts imply that Trump is using legal tax loopholes that only apply to real estate developers like Trump (not deductions that apply to common real estate transactions) to pay absolutely zero or a bare bones minimum in taxes. Trump knows this is an embarrassing political firestorm that will chase away many voters, so better to keep secret.
