Why You May Need a Lawyer

You may benefit from working with a tax attorney when you face an IRS or New York State audit, receive a notice proposing additional tax, penalties, or interest, or need help negotiating payment plans, lien releases, or offers in compromise. Legal help is also useful in New York residency audits, which examine whether you should be taxed as a New York resident, and in sales tax audits of retailers and service providers. Business owners often need advice on collecting and remitting sales tax, handling payroll tax trust fund liabilities, and navigating entity formation and elections that affect state and federal tax.

Property owners in Islandia may need counsel to challenge an assessed value, pursue a Small Claims Assessment Review for an owner-occupied one to three family home, or address delinquent property taxes and potential liens. A lawyer can also assist with tax aspects of real estate transactions such as the New York real estate transfer tax and mansion tax, mortgage recording tax, and 1031 like-kind exchanges. For individuals, counsel can help with innocent spouse relief, unfiled returns, cryptocurrency reporting, offshore disclosure, and the tax implications of life events such as divorce, inheritance, and starting or selling a business.
