It depends.
If there is a balance due on your 2016 tax return, you may want to submit an estimated payment now to prevent yourself from having an 2017 estimated tax penalty. There is a new IRS website where you easily can make tax payments at any time called IRS DirectPay.
If there is a refund on your 2016 return, you are not required to make the 2017 estimated payment but you can choose to make the payment.
