Around 40 per cent of the city's hotels, restaurants, fast-food shops, guest houses and beauty parlours are yet to have tax files despite running full-fledged business, according to a preliminary estimate by the taxmen.
There are around 7,000 of such business organisations in the city.
To bring these service-providing entities under tax net, the National Board of Revenue (NBR) is going to start a special survey today (Sunday).
Taxmen suspected that many of the recently launched businesses involved in providing such services do not even have Electronic Taxpayers Identification Number (e-TIN).
Three teams of the Dhaka Income tax zone-7 will visit the business establishments to collect information till October 30 next and check their tax payment status.
The survey is a part of the NBR's country-wide Income Tax Survey-2016.
The revenue board in 2011 established the tax zone-7 office, giving it special responsibility of collecting income tax from the sectors along with other regular activities.
There is no such specific data in the NBR on how many of these businesses were operating in the city.
This is the first-of-its-kind survey on those areas to make a data bank.
The survey team will take measures to issue e-TINs, either instantly or later, after examining the collected information, and collect tax from the businesses found eligible.
If the survey officials found tax defaults by the businesses, they would have to pay tax from the year they started the businesses.
The tax zone-7 has already issued public notices informing the entrepreneurs about the survey and asking them to display the e-TIN certificates, if they have, at a noticeable place of the business premises during the survey period.
