Housing society maintenance amount from rental income

I have a flat in Indirapuram which is on mothly rent of Rs 25000 + Housing Society Maintenance of Rs 2000/-. My tenant deposits Rs 27000/- in my account every month. I pay the monthly housing society maintenance. For the calculation of Income Tax - Income from Property, Can I show only rental income, i.e.,

25000X12= Rs 300000 and deduct 30% from it (300000 - 90000= Rs 210000) as my Annual Income from Property ?

Or I have to include monthly maintenance paid to the housing society in the rental income ?

Thanks!
