As we countdown to Tax Day, Social Explorer takes a look at Americans dedicated to working on taxes. Detailed Census Bureau data on occupations offers a glimpse into the world of tax professionals.

• According to the 2015 five-year ACS, there were 50,499 "Tax Examiners and Collectors and Revenue Agents" and almost the same number of "Tax Preparers" (49,183).
• Comparing this period with the earlier 2009 five-year ACS data, the number of tax preparers grew from 40,088 in 2009 to 49,183 today–an increase of 22.7 percent.
• Meanwhile, the number of tax examiners decreased slightly from 51,886 in 2009 to 50,499 today, a change of -2.7 percent.
• Tax preparers used to earn 2.6 percent more than examiners, but today, professionals on both sides of the tax process earn neraly identical incomes: $51,858 for tax examiners and $51,888 for tax preparers.
