SAP Note 12567 - Handling time-dependent taxes (U.S.A.)

Symptom:

Program : SAPMF82T
Time-dependent taxes should be created.

Cause and prerequisites

Requirement of the American market.

Solution
The condition records for the US taxes are provided in table A053
and have an expiration date in the key (A053-DATBI) and a valid
from date in the functional part (A053-DATAB).
In Customizing (FTXP), you specify the valid from date. The
expiration date is automatically set to year 9999.
This way you can easily represent changes to the percentage rate
in the future:
You maintain the percentage rate 6.8% as of 01/01/1995, a 2nd
condition record is created and the 1st is changed as follows.
old: new:
Start End % Start End %
01/01/1992 12/31/9999 6.5 01/01/1992 12/31/1994 6.5
01/01/1995 12/31/9999 6.8
In case of changes to the percentage rate in the PAST
(retroactive), the specifications COMPLETE must be recreated
again.
Example: as of 01/01/1993, 6.3 % should be effective:
1. FTXP, as of 01/01/1993, 6,3 %
2. FTXP, as of 01/01/1995, 6.8 %
If you leave the 2nd out, 6.3 % are valid up to year 9999!
The condition record number stands in the documents, the condition
records themselves are not deleted so that evaluations and tax
reporting are still possible.
