Every year there are millions of people who owe $0 in federal income taxes even with modest middle class incomes due to deductions, personal & dependent exemptions, and tax credits. Many of those people will get refunds even with $0 withheld (or refunds larger than the amount withheld from their checks) through refundable credits. The two most common refundable credits are earned income credit and the additional child tax credit.
You haven't provided any details of your situation such as what is your total income and do you have any dependent children? so its impossible for us to say whether or not you'll be one of the people who qualifies for those refundable credits and gets a refund even with $0 withheld.
Its also possible that you will have $0 tax liability but not get any refundable credits, so you would not get a refund but would not owe. Or maybe you'll owe money - possibly a lot plus penalties.
We just can't say because you didn't provide any info.
My suggestion is to look at your last pay stub and calculate what you expect your total income to be this year: look at the year -to - date total for taxable wages, then add the amount you expect to earn on the remaining paychecks this year.
Then go online and search for a tax calculator - all the major tax software programs have free calculators, as do many other financial websites. Plug in your estimated income and basic info about marital status, number of dependent children, etc and see what it says.
