New York Property Tax & STAR Exemption Calculator
Model a New York residential property-tax bill under RPTL § 425 (STAR), § 467 (Senior Citizens), § 458-a (Alternative Veterans), and § 459-c (Persons with Disabilities). Determines Basic vs Enhanced STAR eligibility under the $250,000 household-income cap added by 2019 amendment and the annually-indexed Enhanced STAR ceiling ($107,300 for 2025, ~$108,800 for 2026), surfaces the post-2015 income-tax-credit mechanic vs the pre-2015 direct-exemption mechanic (same dollar value, different delivery), and computes the stacked § 458-a veterans exemption (15% basic + 10% combat + 0.5 × disability rating, capped at a representative local maximum of 50% of assessed value).
NY Tax Law § 1402 (State RPT) + § 1402-a (State Mansion Tax)
New York Real Estate Transfer Tax Calculator

Code § 11-2102, 1.0%-2.625% by class and threshold), and the NYC Additional Tax on residential $2M+ (NYC Admin. Code § 11-2102.1, flat 0.25%). Surfaces the customary seller / buyer allocation and flags the § 1409 LLC-purchaser disclosure requirement added by 2019 reform.

NYC Rent Stabilization Renewal Increase Calculator
Compute the maximum lawful renewal rent on a rent-stabilized New York City apartment under the Rent Stabilization Law (NYC Administrative Code § 26-501 et seq.) as amended by the Housing Stability and Tenant Protection Act of 2019 (N.Y. Laws Ch. 36). Applies the current NYC Rent Guidelines Board order (Order #56 for the 2025-2026 cycle: 3.00% on a 1-year renewal, 5.25% on a 2-year renewal), models the tenant's RSL § 26-511(c)(4) absolute right to choose between a 1-year and a 2-year lease, layers any active Major Capital Improvement (MCI) or Individual Apartment Improvement (IAI) add-on, applies the post-HSTPA preferential-rent-as-ceiling rule, and surfaces the elimination of the 20% vacancy bonus on apartments turning over after June 14, 2019. Covers approximately 966,000 NYC apartments under rent stabilization — the largest regulated rental stock in the United States.
