More About CP&A Our Leadership
We're Always Expanding

Our greatest strengths lie in overcoming the challenges presented by a dynamic market. As Casey Peterson and Associates has watched its clients evolve with the developing community, a similar transformation has taken place within its very own personnel and physical workspace. Time and progress has populated our workforce to nearly fifty employees and two locations. Our expansion as a company has taken our services to a second office of CPAs in Gillette, Wyoming, and spread the Casey Peterson and Associates reputation into the farthest reaches of the region.

In addition, the 2011 relocation of our Rapid City accounting firm from its original downtown office space to the first floor of the Turnac Tower is a prime indicator of our growth and accomplishments. We invite you to stop in at our new home and sample the refinement of our state-of-the-art surroundings.

2014 Retroactive Extenders Bill Passed

Tax Law ImagePresident signs retroactive extenders bill into Law for 2014
In the recently enacted "Tax Increase Prevention Act of 2014," Congress has once again extended a package of expired or expiring individual, business, and energy provisions known as "extenders." The extenders are a varied assortment of more than 50 individual and business tax deductions, tax credits, and other tax-saving laws which have been on the books for years but which technically are temporary because they have a specific end date. Congress has repeatedly temporarily extended the tax breaks for short periods of time (e.g., one or two years), which is why they are referred to as "extenders." The new legislation generally extends the tax breaks retroactively, most of which expired at the end of 2013, for one year through 2014.

We're providing you an overview of the key tax breaks affecting businesses that were extended by the new law. Please call our office for details of how the new changes may affect you or your business.
