The Treasury Department publishes withholding tax collections every business day. Going back to 1998, that makes for thousands of records in our database, and many chances to make mistakes. However, our data has been painstakingly cross-checked, and we have total confidence in its accuracy.

Remember that the federal fiscal year begins in October. So, to find the annual total for 2007 for example, you need to pull up the report for the last day of September 2007. Also, keep in mind that the Treasury’s numbers don’t ’round to totals’, so totals are often off by a little bit.
