What is included in the T T L payments these are payments you make to pay employees tax deductions.?

Treasury Tax and Loan (TT&L) payments consist of federal income taxes deducted from employee paychecks made directly by business firms to depository institutions, rather than in the US Treasury's accounts at the Federal Reserve, thereby allowing the tax payments to remain in the banking system. The TT&L program aids in maintaining the stability of financial markets by reducing uncertainty about the supply of reserves in the banking system and simplifying the Fed's implementation of monetary policy.
