The enormous white marble tomb, listed as a UNESCO World Heritage Site, can attract at least 50,000 visitors a day on the weekend, according to a spokesman for the Archaeological Survey of India, which oversees the Taj Mahal.
Currently it draws at least seven million visitors every year and was recently described by Tourism Minister Alphons Kannanthanam as "India's pride."
The cap will come into place from April 1 and will apply to both local and international visitors, Dimri said.
The spokesman said there was no suggestion of a cap on the total number of visitors to the Taj Mahal at this stage, saying it would be wrong to deny people who had come from far away to visit the monument a ticket.
But he said there had been discussions on putting further limits on the "carrying capacity" of the Taj Mahal at a future stage, though he would not elaborate further on what this would entail.
