Accountants in Riverdale, the Bronx
Our office is on College Road. Co-op owners, professional practices and the institutions along Riverdale Avenue.
Riverdale feels suburban and is not. It is the Bronx, which means New York City, and the number of people who get that wrong on a return is higher than you would expect.
The local economy runs on institutions. Manhattan College sits next to our office, and the concentration of private schools including Horace Mann, Riverdale Country School and SAR Academy supports a professional services economy around it. The commercial corridors are Riverdale Avenue, Johnson Avenue, Mosholu Avenue and Broadway, with Wave Hill and the Fieldston historic district defining the western side.
Local tax
Co-ops, and a tax border four miles north
Riverdale is co-op country, and co-ops are taxed differently from the houses and condos most guidance is written for. You do not own real property, you own shares in a corporation with a proprietary lease. The deduction for mortgage interest and real estate taxes comes through as your allocated share of the corporation’s own costs, reported to you annually, not from your own bills. Flip taxes on sale are set by the building. A personally occupied co-op does not generate a Schedule E. These are the errors we see most often on returns prepared elsewhere.
The other Riverdale specific point is geography. You pay New York City resident income tax and sit in MCTMT Zone 1 at 0.60%. Cross into Yonkers four miles north and you pay no city tax at all, you pay a Yonkers resident surcharge of 16.75% of net state tax instead, and your MCTMT rate drops to Zone 2 at 0.34%. People move across that line regularly, and the part year filing that follows is where things go wrong.
The professional practices around the institutional cluster are mostly S corporations and PLLCs, where the S corporation exemption from the Unincorporated Business Tax is the planning lever worth looking at.
Figures above are drawn from the New York State Department of Taxation and Finance, the New York City Department of Finance, the US Census Bureau, New York City Small Business Services and the relevant town and village codes, and were current in October 2026. Local rules change, so confirm anything you plan to act on.

Frequently asked questions
How do I deduct anything on a co-op?
Through your allocated share of the corporation’s mortgage interest and real estate taxes, which the corporation reports to shareholders annually. You do not deduct your maintenance payment as such. Using the maintenance figure instead of the allocated share is the most common co-op error we correct.
Is Riverdale in New York City for tax?
Yes. The Bronx is one of the five boroughs, so city resident income tax applies in full. The neighborhood’s character leads people to assume otherwise, and the assumption is expensive.
I am thinking of moving to Westchester. What changes?
You stop paying New York City resident income tax. If you move to Yonkers you pick up the 16.75% resident surcharge; in most of the rest of Westchester, including Scarsdale, there is no local income tax. Your MCTMT rate falls from 0.60% to 0.34%. In the year you move you will file as a part year resident, which is where the care is needed.
