29 May 2018 Sir,
I had normally filed my ITR-1 for AY 2017-18 for a tax refund of Rs 170/-. The AO made a mistake and adjusted the tax refund against an old tax demand of Rs 528/- pertaining to AY 2009-10( which was already paid and was already visible in FORM 26AS of AY 2009-10). I immediately filed rectification request with the facts. But when no reply comes even after months, I filed a query for AO. No answer for a month, I files another query to AO for correcting the maistake and paying me the refund after processing the rectification request pending. Then I get a mail message from ITO, Ward 68(2) informing that the tax demand of Rs 528/- has been cancelled, but no refund was send. In fact the demand was made 0, but the adjustment of tax refund against the wrong demand was not corrected. I again send query pointing out the mistake and request for refund. The query was forwarded to CPC, saying that they will give refund. But CPC replies that there is no refund due ( since adjustment was not corrected by AO). I spoke to CPC, and they said refund will be sent by ITO. I again raises a query, and again ITO forwards to CPC, and they again reply that no refund is due.
Sir, please guide me what should I do now. Should I file another rectification or contact whom for refund.
With Regards,
