Hi Bujjulu,
If you refer the case - CIT vs Durga Khote
If person enters into a contract with several film companies for acting in films at a remuneration fixed in each contract, then this income is from profession and not from salary.
If this is the case, then you cannot treat this income as salary income. If person has income from business / profession, then file ITR 4 / ITR 4S.
In respect of refund, I guess you have filed ITR 1 physically. In case of e-filing, refund is generally received by assessee within 3 / 4 months. However, if you have e-filed ITR 1 last year and still you have not got refund, then you must have got some communication from CPC. Otherwise, ask concerned AO directly.
