Frequently Asked Questions

Where does this data come from?

All data comes from USASpending.gov, the official source for federal spending data mandated by the DATA Act. The site is maintained by the US Department of the Treasury and provides comprehensive information on federal awards, contracts, grants, loans, and other financial assistance.

How often is the data updated?

USASpending.gov updates its data daily as federal agencies submit award information. We re-process our contractor profiles and rankings regularly to reflect the latest available data.

What counts as a federal contractor?

A federal contractor is any company, organization, or individual that receives money from the US government through contracts, grants, loans, or other financial assistance. This includes defense contractors, IT companies, healthcare providers, construction firms, and research institutions.

Can I use this data for research?

Yes. All federal spending data is public record under the DATA Act. TaxDollarData makes this data more accessible and searchable, but the underlying data is freely available from USASpending.gov.
