Step-by-Step Guide
Find the property
Search by address on RegWatch or DOF's property tax portal.
Review tax data
Check assessed value, market value, tax class, annual tax, and any outstanding DOF balance.
Check for liens
Properties with unpaid taxes may have liens from the annual tax lien sale. RegWatch flags these automatically.
Review exemptions
Check for STAR, 421-a, J-51, ICIP, or other exemptions that reduce the tax burden.

NYC has four tax classes with different assessment ratios. Understanding how a property is classified and assessed is critical for investment analysis and tax appeal evaluations.
