Do tenants in Flatiron pay the NYC Commercial Rent Tax?

Yes, for larger leases. Flatiron is in Manhattan below 96th Street, where the city's Commercial Rent Tax applies. A tenant owes it only when base rent for the space is $250,000 a year or more. The tax is 6% of base rent after a 35% reduction, so 3.9% of rent, with a sliding credit between $250,000 and $300,000, and the Small Business Tax Credit wipes it out for businesses with total income of $5 million or less and base rent under $500,000.
