I made 27,000 this year 11,000 more then last year why is my return less?

There is no way to answer your question without knowing details of your tax situation. The amount of income can affect some credits such as EIC. The more income you have, the more tax you must pay and you may not have increased your withholding enough to pay the additional tax. If you decreased your withholding because of the tax cuts, you may have received what you would have gotten in a refund in your take home pay every pay period.

Also, if a person has a period of very low income and then a period of monthly income one year and the following year has about that monthly income pretty much all year the refund in the first year will usually be substantially greater that the second.  The reason: the about withheld each paycheck will work out to be about right if you earn at that rate all year.  If you don't, then it turns out to be too high a rate so you get a bunch back.
