It includes links to:
- Revenue proposals
- Tax expenditures
- International tax
- Office of Tax Analysis (OTA) Technical Papers
- OTA Working Papers
- Office of Tax Policy Reports
- Foreign Account Tax
- Compliance Tax
- Other international documents
- Tax analysis
- Tax regulatory reform
- Tax Information Exchange Agreements (TIEAs)
- Treaties
How Does the Federal Gov't Use Our Taxes????
FiscalData.Treasury.Gov answers that question! It's a deep dive into the Treasury Department's weeds.
Some of the FiscalData.Treasury.Gov's datasets include:
- Daily Treasury Statement (DTS), which provides data on the daily cash and debt operations of the US Treasury, including cash balance, deposits, and withdrawals; tax deposits and refunds; and debt transactions.
- Historical Qualified Tax Credit Bond Interest Rates
- US Government Revenue Collections
- And so, so, so, many more spreadsheets.
USASpending.Gov
A broader open data source of government spending than FiscalData.Treasury.Gov. It has lots of interesting stuff about COVID-19 spending information, which is pretty neat.
