Before you build: what Sea Cliff looks like from a business owner’s chair

27.6% of Sea Cliff workers work from home, against 14.9% across New York. People working from home notice local businesses during the day and book services from the same laptop they work on. Daytime appointments, clear prices and an email that gets answered suit this audience; say how you schedule work.

Self-employment is strong in Sea Cliff: 18.7% of workers run their own business (New York: 9.7%). For a one-person business, the website is the storefront, the brochure and the business card at once, and many have nothing but a social media page. Put your name and photo on the website: customers hire you, not a logo.

The legal basics for Sea Cliff businesses online

A few rules apply to any Sea Cliff business that sells or advertises online:

  • Under the Americans with Disabilities Act, businesses open to the public must make their goods and services accessible to people with disabilities, and the Justice Department’s guidance says that includes their websites. ADA.gov guidance
  • Out-of-state sellers have to collect New York sales tax once they reach the state threshold: BOTH tests must be met in the immediately preceding four sales tax quarters: cumulative gross receipts from sales of tangible personal property delivered into New York exceeded $500,000 AND more than 100 such sales. Official source
  • The New York State sales tax rate is 4%; cities, counties and school districts add local rates (roughly 3% to 4.75%), plus an extra 0.375% inside the Metropolitan Commuter Transportation District. New York State Department of Taxation and Finance

Rules change and details vary by business; this is general information, not legal advice.
