Lawyers and engineers are the most likely occupations to hire professional tax preparers, according to newly released statistics.
Maintenance workers, food service professionals and members of the military are the least likely to hire tax professionals, according to data from Cambridge Analytica, a provider of data analytics and behavioural communication. In between those two extremes were occupations such as civil servants, clerical workers, computer professionals, financial services, manufacturing workers and medical professionals.
Cambridge Analytica also examined some other demographic factors. It found that people aged 45 and older are substantially more likely to use professional tax services than younger people. Males were more likely to use professional tax services than females. Married people are more likely to use professional services, compared to singles.

Individuals who earn over $125,000 a year are 55 percent more likely to use professional tax services, compared to a little less than 20 percent for those earning $50,000 to $75,000 per year. People who live in cities are only slightly more likely to use professional tax services than those who live in rural areas.
