New Treasury Account Symbol (TAS) format

Treasury transitioned to a new Treasury Account Symbol format. The following two formats are being retired:

  • Pre-GWA Format: 2868704 -- The Agency Code is the first two positions, and the Fund Year is a single-digit in the third position ("6" for 2016).
  • Alternative Format: 2816704 -- The Agency Code is the first two positions, and the Fund Year is two digits in the third and fourth position ("16" for 2016).

The new format is known as the Component Treasury Account Symbol. The new format shows the start and end year(s) of the appropriation used on the funding for the purchase.

  • Example (Annual Funds): 02820162016 8704000 -- The Agency Code is the first three positions, and the annual appropriation is available for obligations only in 2016.
  • Example (Multi-year Funds): 02820142016 8704000 -- The multi-year appropriation is available for obligations starting in 2014 and ending in 2016.
  • Example (No-year Funds): 028 X8704000 -- The no-year appropriation is available for obligations at any time after the appropriation is approved and until it is rescinded or fully liquidated.

Customers may provide any of the above three formats (Pre-GWA, Alternative, or Component) in the short-term; GSA will automatically convert the Component Treasury Account Symbol format for all IPAC transmissions. However, as of October 1, 2014, customers were and are strongly encouraged to begin using the Component format, as this will be the only format accepted by Treasury for IPAC transactions across the Federal Government.

Treasury’s SAM Public Website is a reference source for the new format of Treasury Account Symbols for federal agencies.

Change to Civilian Billing Schedule

Civilian customers had a change to their previous billing schedule. Billing statements for Civilian customers were previously generated once a month around the 20th of the month. That schedule has now changed for Civilian Customers to twice a month. The first billing cycle occurs on the 8th of the month, and the second billing cycle occurs on the 22nd (or the next business day for both of these dates if they fall on a weekend or holiday).

There was no change to the billing schedule for DoD Customers.
