Populating Check Box Based on Date Field


Does anyone know what's wrong with this formula? I have this formula in a check box field. I'm trying to check if the Receipt Date is greater than 5/1/18 and if yes, I want it to put a check in the checkbox. What did I do wrong with the formula? Any help is appreciated!


=IF([Receipt Date] > DATE(2018, 05, 01), 1, 0)
