Editor's Review

VerifiedLawFirms editorial

Focus and practice areas

The whole of the work here is tax. The firm handles federal and New York State tax matters for individuals and businesses, and it operates from Garden City on Long Island. Its clients include people who owe back taxes and those who face audits or collection action.

Tax controversy is the practice of resolving disputes with a tax authority. It begins once a return is questioned or a balance goes unpaid, and it moves through the offices and review boards that decide such matters. The firm's pages describe that kind of work in plain terms, which gives a prospective client a clear read on scope.

The tax matters handled

The service list on the firm's site is long and specific, which helps a reader gauge what the firm actually does. On the audit side, it covers IRS and New York State tax audits, IRS Appeals, and New York State Conciliation Conferences. On the collection side, it covers liens, levies, warrants and seizures.

The firm also lists routes that reduce or restructure a balance owed: offers in compromise, installment agreements, and penalty abatement. Other named items include trust fund recovery penalties, responsible person assessments, New York State residency audits, driver's license suspension matters, and voluntary disclosures.

What some of these services involve

Several of these terms carry weight for anyone new to them. An offer in compromise is a request that the IRS accept less than the full amount owed, and the agency weighs income, expenses and asset equity before it agrees. An installment agreement sets a monthly payment schedule for a taxpayer who cannot clear the balance at once. Penalty abatement asks the IRS to remove penalties where the taxpayer can show reasonable cause.

The collection tools run in the government's favor. A lien is a legal claim against property for an unpaid tax debt, a levy is the actual seizure of funds or assets, and a warrant is New York's recorded claim that can follow a taxpayer's property. A firm that lists all three is set up to step in at different stages of a collection case.

Trust fund recovery penalties and responsible person assessments both reach individuals behind a business. When a company fails to pay over payroll taxes it withheld, the IRS and New York can pursue the people who controlled those funds. These cases turn on who had authority and knowledge, so the facts of each role matter.

Appeals and disclosure options

The appeals routes sit between an audit and a courtroom. IRS Appeals gives a taxpayer a review by an office separate from the examiner who ran the audit, and a New York State Conciliation Conference offers a comparable state-level review before a case goes to a formal tribunal. Voluntary disclosure runs earlier still, where a taxpayer comes forward about unreported income before the government finds it. Naming these steps shows the firm works across the timeline of a tax dispute, early and late.

Where the firm works and for how long

The firm is on Long Island and takes both federal and state matters, which fits a client base that files with the IRS and with Albany at the same time. New York runs its own audit and appeals system, separate from the federal one, so a taxpayer can face two tracks together. The firm's list of state-specific services, including Conciliation Conferences and residency audits, reads like an answer to that double exposure.

A New York residency audit deserves its own note. The state examines whether a person who says they left truly changed domicile, and it looks at where someone keeps a home, spends time and holds business ties. These audits often turn on records, so careful document work carries the case. In my opinion, a firm that names residency audits as a distinct service is signalling that it meets this New York issue often.

Karen Tenenbaum founded the firm in 1996 and began as a solo practitioner. The firm states it has concentrated on tax dispute resolution for more than twenty-seven years, a span that lines up with that start date. Long attention to one narrow field tells a reader the firm has stayed with the work across decades.

Who built the firm

Karen Tenenbaum shaped the firm from its start. She worked as an accountant at large accounting firms, then as a tax attorney at two law firms, before she launched her own firm in 1996. She was a tax attorney and a certified public accountant, and she ran the firm as Managing Partner.

Her dates were 1959 to 2023, and the firm's home page carries them. That accounting-then-law path matters for the work, since tax disputes lean on numbers as much as on statutes, and a founder who read both sides could build a firm around that overlap. Tenenbaum Law also names Bradley Dorin among its tax attorneys.

What the site puts on the record

The firm's about page names recognition from several publications, among them the New York Law Journal, Super Lawyers, Long Island Business News, and Long Island Press. These sit on the firm's own pages, and a reader can weigh them for what they are: mentions in legal and regional business media.

As a reviewer, I read this listing as a focused tax controversy firm with a clear founder story and a defined service menu. The facts the site publishes point in one direction, toward federal and New York tax disputes for individuals and businesses. Tenenbaum Law has worked in that field from Long Island since 1996.
