You may be due an additional refund even though you are increasing your income. The natural thought is if I made more money I must owe more tax but this is not always the case. Certain credits you may have been eligible for in 2019 such as the Additional Child Tax Credit and Earned Income Credit may actually get larger as you have more earned income which will result in an additional amount being refunded to you. It depends on your exact tax situation, but it is definitely possible that adding more income to your 2019 tax return results in the IRS owing you more money than they originally refunded to you.
