In 15CB there is a point for payment toward supply of article or things (e.g. plant,equipments) but in form 15 CA in the field nature of remittance option regarding such payment does not exists and the field is mandatory field.How should I proceed ?
In Form 15CA, write the nature of remittance as per the agreement or the invoice.For eg:- fees fro technical services, reimbursement of expenses,payments towards training expenses of the employees, payment towards purchase of fixed assets etc as the case may be with you.
In form 15CB, if it is supply of articles or things (plant ,equipments), then write yes otherwise write no.
In form 15CA just below the "Nature of remittance as per agreement/ document " you will find "In case of Other Income please mention nature of remittance".fill this part and try uploading it.
If you have to write on your own you write trade remittance if it is a payment for imports against form A1. Normally TDS is on FTS and Royalty in case of machines and software even if there is no Branch or DAPE.
