"I'm a CPA, but when my clients have sales and use tax issues, there is only one person I'll turn to and that's Keith Crichton. He is the authority on the subject and there is no close second"


Jeff Prager, Founder, Backroom Management Services, LLC

Sales and use taxes have become a gold mine for state and local governments, which are using much more aggressive audits.  In some cases there are no statutes of limitations on how far back they can assess, penalize and collect.  And there are evolving federal efforts to allow states to force out of state retailers to collect their sales and use taxes for them, which would open those retailers to audits by all states.


Crichton Consulting Services will help you determine what your responsibilities are, and solve any problems you may already have, even those you may not know about.

Keith Crichton has over 25 years experience in tax consulting, corporate tax management and public accounting, especially in the income and sales taxes of all 50 states.  In recent years he has been a consultant providing accounting and tax services to multiple medium to large companies in the Denver area.  Prior to that he had been a tax and accounting consultant with a major international consulting firm, head of the tax departments for two closely held Denver companies with operations in multiple states.


In 2009 Keith formed Crichton Consulting Services, LLC to narrow his focus to only Sales and Use Taxes, and to apply his extensive multi-state experience to a type of tax that is frequently overlooked by many companies.  He assists small to mid-sized businesses with the challenges they face from the increasing number and intensity of Sales and Use Tax Audits being done by States, as well as City governments in Colorado.


Keith holds a Master of Taxation from the University of Denver, an MBA from the University of Colorado and a B.S. in Accountancy from Miami University in Oxford, Ohio.  He is a Certified Public Accountant and a Member of the American Institute of Certified Public Accountants, the Colorado Society of Certified Public Accountants and the Financial Executives Networking Group.  He enjoys traveling with his wife and their dogs, automobiles and auto racing, golf, music and movies.

For Business Owners, CFO's or Controllers

For CPA Firms and their Clients

The following is a sample of the types of services we provide.



For the Business Owner, CFO or Controller


NEXUS REVIEWS - Most likely you are focused on the day to day operations and growth of the business, not on sales taxes.  But as the business expands its operations, you may create sufficient connections with another state (or Colorado city) so that they can require that you collect their sales or use taxes.  This is called Nexus.  If a company is found to have Nexus, but has not collected sales or use taxes and filed returns, they can be held liable for the uncollected taxes for an unlimited period of time in the past.


A Nexus Review is a study of the operations of a business to determine if there are any locations where it makes business sense to collect sales or use taxes from customers and file returns.


AUDIT MANAGEMENT AND DEFENSE – in the past we have reduced assessments by as much as 80%.  We will also help prepare for an upcoming audit, and would prefer to do so, if possible.


VOLUNTARY DISCLOSURE AGREEMENTS – many states and cities have programs which allow a taxpayer to voluntarily declare that they should have collected and paid taxes but failed to do so.  In these cases penalties and the periods of time for which back taxes will be due are commonly reduced significantly.


TAX QUESTIONS – rapidly expanding businesses often want to know what products or services are taxable, and what their collection responsibilities will be before they begin an expansion into new states or Colorado cities.


TRANSACTION PLANNING – just like income tax planning, when a business has a significant transaction upcoming which involves tangible personal property, then sales taxes should be considered in addition to other taxes.  Further, the definition of tangible personal property varies from one location to another.
