Specialties of Expertise

Valuation Consultation and Appraisal Review

During Mr. Perlmutter's 27 years at the Internal Revenue Service, he has selected for audit and reviewed thousands of valuation appraisals. Mr. Perlmutter has gathered the knowledge and experience to identify appraisals that are credible and reliable and those possessing "red flags" with significant weaknesses and faults.

Mr. Perlmutter understands that it is important to follow valuation industry standards of report writing.  Adequate analysis is key, as is providing appropriate data to support the appraiser assumptions and conclusions. Just presenting studies  and court cases is not enough. 

Mr. Perlmutter has helped clients in determining the potential for an IRS audit of their valuation appraisals as well as their potential financial risk exposure due to an IRS audit.   He has also assisted appraisers with strengthening their valuation reports to better withstand potential IRS scrutiny.

One of the valuation areas Mr. Perlmutter specializes in is determining the fair market value of partial interests in business entities and fractional interests in real property.  Valuation discounts are considered and applied where appropriate.  All valuation conclusions are supported by analysis and data. 


The bottom-line is Mr. Perlmutter knows how to spot "red flags", those errors, omissions and inconsistencies that lessen the credibility of the appraisal.  Eliminating these damaging "red flags" may decrease the chances of an IRS audit, potentially saving money and the associated stress of an audit.

Intellectual Property Valuation

This is a highly specialized field that is receiving increased scrutiny by the IRS. Mr. Perlmutter has reviewed and actively helped prepare may intellectual property valuation appraisals, which include name and likeness rights (Right of Publicity) and revenue streams from copyrighted music and film royalties.  


Mr. Perlmutter has written Intellectual Property valuation training materials for IRS new hire attorneys, he has made presentations on a national scale to IRS attorneys, has presented the IRS position at Appeals conferences and had been actively involved in many aspects in a significant tax court case that involved intellectual property valuation, business valuation and discounting of partial interests. 

Mr. Perlmutter has reviewed many poorly written and poorly supported IP appraisals.  He can spot the weaknesses and "red flags".  So can the IRS.   And Perlmutter knows what constitutes a well written, defensible IP appraisal.  Mr. Perlmutter can guide you through this process.
