Probably. It will likely increase your refund. However, there are a lot of variables, so it is difficult to give you a definite answer.
Also, in connection with the new law, your employer should be reducing the amount of taxes withheld from your paychecks. That means that part of the new law's tax cuts will increase your paychecks, rather than increasing your refund. For example, let's say the new tax law will result in saving you $1000. It may only increase your tax refund by $500 because your paychecks have increased $10 a week ($10 times 50 weeks=$500).
