Screen shot:


Governments around the world are changing tax policy on a regular basis. As a result there is a need for businesses to keep their accounting packages in line with government policy. With many of the existing accounting packages, there is no way for the user to generate their own set of payroll tax tables. This data is stored in data files, but the average user is generally not computer literate enough to modify the files directly. Presumably this functionality is not already built into these packages in order to force users to upgrade every 12 months.

MyTaxTables is a small open source free software utility that will allow the user to directly make basic changes to the tax rates. e.g. Change payroll tax in the $30,000 - $40,000 tax bracket from 25% to 27%.

The initial package targeted is the MYOB® Premier 8 accounting software and the initial was be to be able to edit a pay2myob.bin import file for payroll tax rates. The formats of other data files from other accounting packages will require more investigation.

The software will accept as inputs values the tax rates and salary brackets as published by various government tax agencies. The software will output a file that can be read by the applicable accounting package.
