As I enter my expenses for my rental house, maintenance, repairs etc my tax debt increases instead of staying the same or decreasing as it should. Anyone else noted this?

Sometimes as your income decreases your tax increases. This could be the case if you qualify for an earned income credit, for instance, as the credit may decrease as your income decreases. I suggest you look at your Form 1040 before the additional expenses are entered and after to see what is changing. Pay particular attention to schedule 3, Additional Credits and Payments. The credits reduce your tax but often they will be reduced in response to a reduction in your income. Also look on line 13 of form 1040, that is your Qualified business Income deduction. It may also decrease as your income decreases. Your earned income credit will be listed on line 27.
