"Taxes must be collected from the taxpayers while behaving properly. The law or rules shall be amended for that if necessary," he said at a function at the Raowa Convention Hall in Dhaka on Thursday.
The NBR organised it to observe the National VAT Day-2014 and to award the top VAT payers.
NBR acting Chairman Md Farid Uddin presided over the programme which was also attended by the Prime Minister's Economic Affairs Adviser Mashiur Rahman and State Minister for Finance MA Mannan.
Joining the discussion at the beginning, Dhaka Metropolitan Shop Owners Association President Toufique Hasan said, "VAT officials (of the NBR) are raiding the shops in the capital and confiscating documents during peak business times ahead of the Eid."
His remarks were greeted with applause by traders.
The association's Secretary General M Rezaul Karim Sarkar said, "The culture of paying tax is yet to be established in Bangladesh. We are VAT collectors. We are supposed to collect VAT from the consumers and give it to NBR."
"But we cannot force them (consumers) to pay VAT when they come to a restaurant to eat. So, why should we pay this VAT to NBR year after year? We should not be doing that," he said.
Traders said tax should be collected properly, instead of raising the rate and emphasised more public awareness campaign.
They sought the government's supervision so that the taxpayers are not harassed.
In his address, Tofail asked the NBR to not harass the businesses.
"You (NBR) need to be more careful instead of confiscating the ledgers during Ramadan."
