Buying a business on Long Island

What's different about buying on Long Island

Four things make Long Island acquisitions structurally simpler than NYC and distinct from the rest of the state:

1. No NYC taxes. No NYC Business Corporation Tax, no Unincorporated Business Tax, no Commercial Rent Tax. Long Island businesses file NYS taxes only ^[1] .
2. No NYC permit overlay. No NYC DOHMH, no NYC DCWP, no NYC Fair Workweek. Long Island businesses deal with NYS licensing plus county/town permits — a shorter path to closing ^[3] .
3. High property taxes. Long Island has some of the highest property taxes in the U.S., driven by school district taxes. For real-estate-inclusive deals or commercial rent, this is a material operating expense.
4. LIRR-driven geography. Long Island's commercial corridors cluster along the LIRR. Businesses near commuter stations have different customer bases than those in central or eastern Suffolk.

County-level detail. This page covers Long Island as one region. For the establishment counts, size bands, wage data and diligence specific to each county, see buying a business in Nassau County and buying a business in Suffolk County.

Nassau vs. Suffolk

Long Island is two counties — and they're not interchangeable.

County	Profile
Nassau County	Closest to NYC; high-income suburbs; LIRR access to Manhattan; denser commercial corridors; higher commercial rents than Suffolk; no NYC taxes but high property taxes.
Suffolk County	Larger, more diverse; western Suffolk (Babylon, Huntington) similar to Nassau in profile; central and eastern Suffolk more rural and seasonal (Hamptons, North Fork); lower commercial rents; greater seasonal revenue variability for tourism-dependent businesses.

Nassau trades like the edge of the city — comparable customer density and rent, without the NYC tax overlay. Western Suffolk behaves much the same. Central and eastern Suffolk rewards buyers who understand seasonal tourism (Hamptons, North Fork wine country) and the year-round residential base that supports non-seasonal businesses.

Valuation — Long Island-specific factors

Long Island small businesses are typically priced on a multiple of SDE — see the SDE guide for the formula. Three Long Island-specific factors adjust the multiple:

• Property tax burden. For owned-real-estate deals, model property taxes carefully — Suffolk County in particular has heavy property taxes in some school districts. A business that looks profitable on the listing can be thin after property taxes are properly expensed.
• Seasonal revenue (Suffolk). East End businesses can earn most of the year’s revenue in a short season. Get 36 months of monthly figures rather than an annual total — see the Suffolk County guide for how to underwrite it. Reconstruct SDE on a trailing 12-month basis, but stress-test on a worst-month basis — your debt service doesn't take summer off.
• Customer base maturity. Long Island has a large pool of long-tenured owner-operated businesses approaching retirement age — the classic acquisition target. These businesses often have strong neighborhood loyalty but limited online presence. The customer base is real but harder to verify digitally; foot-traffic diligence and on-site observation matter more than digital analytics here.

Aggregated self-reported marketplace data from BizBuySell's Q2 2026 Insight Report ^[6] shows national medians of $349,250 across all industries, $250,000 for retail, and $205,000 for restaurants. Those are national numbers rather than Long Island ones, and they are self-reported. Use as a sanity check, not as a price.

Long Island-specific diligence items

• Property tax verification. For owned-real-estate deals, confirm the current property tax bill and any exemptions (STAR, veteran, senior) that may not transfer to the new owner. Check the local assessor's office, not just the seller's records.
• Sales tax bulk-sale notice. Same NYS successor-liability process applies as elsewhere in the state ^[2] . Combined NYS + local sales tax rate differs from NYC — verify the rate for Nassau or Suffolk specifically.
• Workers' comp, statutory disability, PFL coverage continuity. Mandatory for most Long Island employers ^[4] . Coverage must be in force on day one of closing.
• UI registration (NYS 100). Required with NYS DOL when taking on employees ^[5] . Asset purchase typically opens a new account; entity purchase may continue the existing one.
• Town-level permits. Many Long Island towns (Town of Hempstead, Town of Brookhaven, Town of Smithtown, etc.) have their own business permits — especially for signage, food service, and home-based businesses. Verify at the town clerk's office.
• LIRR-driven foot traffic. For customer-facing businesses, walk the area at different times of day and week. LIRR commute hours generate different traffic than weekend daytime. Don't rely on a single site visit.

Industries that work well on Long Island

Based on the regional profile and acquisition activity, several industries are particularly well-represented in Long Island acquisition volume:

• Restaurants and bars — see the restaurant guide. SLA licensing is NYS (no NYC overlay); LIRR-station-adjacent locations are a known value driver.
• Laundromats — Long Island has a dense laundromat market, especially in multifamily-heavy neighborhoods. See the laundromat guide.
• Home services — HVAC, plumbing, landscaping. Long Island's homeowner concentration makes these particularly stable.
• Auto repair — older housing stock, longer vehicle retention, suburban geography. See the auto repair guide (when published).
• Liquor stores — NYS SLA off-premise licensing applies. See the liquor store guide.
