A new error in ITR-3 is now resolved. If there is exempt income, in Schedule EI, if there is nil agricultural income, it should not be ignored. Gross Agricultural Receipt should be filled up as 0 (zero). If not done, some error message comes at the time of uploading. As advised by CPC, I have now resolved the issue and filed ITR-3. Till CPC rectifies the above bug, assesses may follow the above suggestion.
