Partner firm income tax

Interest given to partners on capital contribution is less than or equal to 12% and must be covered in partnership deed, depreciation as per income tax act will be allowable.

Yes can go for presumptive income as your profit is almost 8% of Total turnover but you cannot claim depreciation and partner interest as these deduction are not allowed in presumptive section. Hence you have to show your profit inclusive of depreciation and partner interest.
