401k contribution reduction > owe tax when filing?

Money is extremely tight right now and I would like to eliminate my 401k contribution for the next 8 months so that I get a little more in each paycheck. Then I'll go back to contributing so I can get my company's match. If I do this, is it possible I'll end up owing money when I file my taxes next year? I have never owed before and I usually get something back.
