A partnership firm is considered as a spearate person/assessee for the pursposes of Tax audit u/s 44AB of the Income Tax Act 1961. Where an assessee carrying on business, if his total sales, turnover or gross receipts, as the case may be exceeds one crore rupees in any previous year is required ot get his accounts of such previous year audited by an accountant.
I am assuming that the commission which you have shown is the only receipts of the business and it is of the previous year 2015-2016, in that case tax audit is not applicable.
Also, for determining the limit of gross receipts you won't deduct the expenses.
Further, filing returns is mandatory for partnership firms even if audit is not applicable . (otherwise you won't be able to setoff the losses.)
