The letter says:
You may file the return electronically or submit to the Commissioner (BTB) of following Regional Tax Office:
LAHORE
Income Tax House, Nabha Road, Lahore
And on my last TCS postage I wrote:
Income Tax Department
Income Tax House, Nabha Road, Lahore
And TCS returned the package undelivered saying the address is incomplete, maybe they tried delivering it and the Tax House guys maybe said they don't know which department the package is for??? So this time I'll mention this:
To: Commissioner (BTB)
Address: Regional Tax Office (RTO)
Income Tax House, Nabha Road near Anarkali, Lahore, Pakistan
What do you say?
