Tax Services
Strategic tax advisors for businesses and individuals
At Lanphier LLP, we believe that a tax return should just be the end product of a year well-planned. Too many firms treat tax preparation as a backward-looking exercise -- assembling documents, crunching numbers, and filing forms after the fact. We take a fundamentally different approach. Our advisory-first philosophy means that by the time we sit down to prepare your return, the strategic decisions have already been made, the planning has already been executed, and the outcomes are already working in your favor.
Our Denver-based team brings decades of combined experience across corporate, individual, fiduciary, and international taxation. We serve business owners, high-net-worth individuals, families, and trusts with a depth of expertise typically found only at large national firms -- but delivered with the personalized attention and genuine relationships that define a boutique practice. Every engagement begins with understanding your goals, your circumstances, and the full picture of your financial life.
Whether you need annual tax preparation, ongoing consulting to minimize your tax burden, or experienced representation in a dispute with the IRS or state authorities, our tax practice is built to serve you at every stage. We integrate seamlessly with our accounting, advisory, and legal services to provide truly comprehensive support.

From complex multi-entity business returns to individual filings and trust and estate administration, our tax preparation team leverages cutting-edge technology and deep technical knowledge to deliver accurate, optimized returns. We offer flat-fee annual agreements so you always know what to expect, and we review your financials throughout the year to ensure nothing is missed.
