Willy and Wendy Wonks, friends of yours, were married on December 30th 2015. They know you are studying taxes and have come to you with a question concerning their filing status. Willy and Wendy would each like to file single taxes for the tax year 2015. Willy has prepared their taxes both as single and married filing jointly, and he has realized that the couple will get a larger combined refund if they each file single. Willy argues "that is not as we were married for very long in 2015." What would you say to Willy and Wendy?
