I expect the first answer is probably right here, but Eurodicautom also gives "salary" as a translation of "traitement", defined thus:

"payments to clerical,supervisory and managerial employees"

So, depending on your exact context, "salary" might be a possibility in some instances, though if the headings are related to the "traitement informatique", then probably stick with "processing" as the first person has suggested.

I think it's simply explanation, explanation of error.

it looks what you have are studies analyzing the company's sales. I believe <traitement> could be treatise, and, more loosely, study.

Taxes are computed, right? And Traitement informatique here would mean something like Computerized Tax Computation

The computation described below

NOTA BENE:
Tax treatment means which category you put a taxable amount in; how you analyse the elements that will be taxed; does it go under taxable, untaxable,

whereas, you do the computation once you have finished the treatment.
In this case, it\'s tricky but they are talking about both a program that computes the tax and the classification into taxable categories. in the case of Traitement informatique, I think it\'\'s computation whereas the others seems to be tax treatment.

I think it describes the basis of tax treatment of computer hardware and software purchases including the amortization and depreciation schedule.

...I should add, the purpose of the investigation being to find any irregularities in the company\'s tax returns.
