Many services–haircuts, lawn care services, and auto repair services, for example--are already taxed in many jurisdictions. On the surface, ‘broadening’ the tax base to include professional services seems a simple option for states. But substantive reasons exist that prove taxing professional services – especially architectural services – makes poor economic sense. In states and localities where the tax is assessed, several realities have emerged. Some clients will seek non-professionals to perform work in order to avoid the extra costs associated with the tax. This conflicts with the goal of state laws that require licensing of design professionals to protect the health, welfare, & safety of the public. The tax may further adversely affect the quality of the built environment by encouraging re-use of old plans to cut costs, thereby reducing new and innovative building design. Small in-state firms confined by the tax loose a competitive advantage to multi-state firms who can farm the projects out to an out-of-state office, thus avoiding the tax. Over 50 percent of AIA member firms have fewer than four employees. Overall, the taxation of architectural services favors out-of-state firms that are not subject to the tax. Since architectural services are high-cost items involving long-term capital expenditures, more clients could turn to out-of-state firms in order to avoid paying the tax. An estimated 30 percent of all 2001 billings from AIA member firms came from federal, state, and local governments, who often exempt their billings from the tax. In the end, many states have found revenues from a tax on architectural services are offset by the cost of additional administration, enforcement and litigation.
