Tax Compliance

Tax planning that supports growth, not just filings.
Tax isn’t just about forms and deadlines, it’s about helping you make smarter decisions with lasting impact. From individuals with complex financial lives to growing businesses and multinational families, we offer a solution for you.

We provide comprehensive services across individual and business tax, international tax, state and local tax (SALT), and tax controversy. Whether you’re navigating multiple income streams, expanding across borders, or responding to an IRS notice, our experienced team is here with insight and clarity every step of the way. 

Where others see complexity, we see an opportunity—for savings, peace of mind, and a stronger future.

DDK is more than a tax firm. We’re your partner in planning forward.

International Tax

International tax goes far beyond paperwork; it’s about protecting what you’ve built across borders and meeting every requirement along the way. No matter if you’re growing across borders or living abroad, we provide the guidance you need.

State and Local Tax

Confusing rules. Overlapping jurisdictions. Constantly changing regulations.

Tax laws are always shifting, and while they can be complex and confusing, they also offer valuable opportunities for savings, incentives, and refunds.

Tax Controversy

Avoiding tax issues starts with smart planning. DDK helps individuals and businesses stay ahead of IRS and state audits—and steps in when representation is needed.

Trust & Estate Planning

You don’t have to be wealthy or run a business to plan ahead; you just need a clear vision for the future. We offer a team that specializes exclusively on trusts and estates to help create plans, something most firms can’t offer.
