Why We Can’t Wait Until 2029

Uncertainty around HDFC taxes past 2029 leaves HDFC's in financial precarity: how are we supposed to make long-term budget plans? Approve loans for the building or support the mortgage of a new shareholder?

We have already seen financial institutions being unwilling to lend because of the risk associated with the projected tax increase.

Advancing a new tax cap for HDFCs or at least extending DAMP will empower buildings and shareholders to access the financing they need. We need to begin conversations now to advocate for HDFC needs across the city.

Calculate Your Tax Bill Without DAMP

Follow the steps to open a quarterly property tax bill, described above
Go to page 2 - multiply the "Billable Assessed Value" by the "Current Tax Rate" ; this would be your total taxes with no exemptions.
To calculate per unit increase:
- Subtract that number by your building's actual "Annual Property Tax" value
- Divide that by the number of units in your HDFC to find the increased per unit cost
