Subnational Taxation

While taxation is an unavoidable part of doing business, effective structural and transactional planning can dramatically reduce your liability. The lawyers at Dentons are intimately familiar with the array of taxes, unclaimed property laws and tax authorities at the state, county and city levels. Trust us to manage the most complex, potentially costly procedures, from structural and transactional planning to corporate and transactional due diligence, as well as tax and unclaimed property audit representation and litigation.


Tax Credits and Tax-Advantaged Investing

Tax-advantaged investing encompasses several markets through which some of the nation’s largest financial institutions and insurance companies invest billions of dollars each year in projects that bring tangible benefits to local communities. Dentons offers an unparalleled understanding of these markets, their economics and the regulatory framework in which they function.

The accounting profession is facing an ever-increasing demand for global services, sector focus, and flexible, innovative solutions. A more rigorous regulatory environment, coupled with heightened global risks and the challenges of providing cost-effective, outstanding client service present the opportunity for you to position your practice beyond the reach of your competitors.
