Does the IRS require 1500.00 in cash giftsto be turn in for taxes?

Under the US tax code gifts are not taxable as income. ("Winnings" are, so if you won the money in a lottery or contest, you do have to report it.)

There is something called a "gift tax", but you'd have to give a single individual considerably more than $1500 in a year for it to kick in.

As of 2014, the annual exclusion is $14,000 (and that's "per person per person" ... you can give any number of people $14,000 each, and a married couple can each give the same person $14,000, so if your parents are so inclined they could potentially give you and your spouse a combined total of $56,000 a year without paying gift taxes on it ... 14k from dad to you, 14k from dad to spouse, 14k from mom to you, 14k from mom to spouse), and the person taxed on gifts over that amount is the person giving the gift, not the person receiving it.
