Nonprofit accounting in Scarsdale, Westchester

With a median home value of $1.8 million and Westchester property tax rates, Scarsdale households are about as constrained by the state and local tax deduction cap as anywhere in the country. For employees there is very little to do about it directly. For business owners and partners, New York’s pass through entity tax is worth modeling properly, because it moves state tax from the capped personal deduction to the entity level.

The returns here are complex for a specific reason: an executive and professional population means equity compensation. Restricted stock units, incentive stock options and non qualified options each behave differently, and the alternative minimum tax still has teeth on ISO exercises. Add the 3.8% net investment income tax, capital gains, partnership K-1s from city law and finance firms, 529 plans and the kiddie tax with a household size of 3.22, and charitable bunching through donor advised funds.

A quarter of residents are foreign born in a highly educated, affluent village, which produces an unusual niche: inbound executives and assignees with foreign pensions, PFICs, treaty positions and Forms 8938 and FBAR behind them.

No local income tax at all, unlike Yonkers four miles away. MCTMT Zone 2 at 0.34%, and the self employment threshold rising from $50,000 to $150,000 for 2026 takes a lot of Scarsdale consultants and board members out of it entirely.

One planning point people miss: the Unincorporated Business Tax follows the business, not the residence. A Scarsdale consultant with a Manhattan office or Manhattan clients can owe New York City UBT while owing no city resident income tax.
