That shocked even many Catalans who were opposed to independence and sparked angry demonstrations against the police.
Some protesters called for Puigdemont to go to jail for holding the independence vote.
The country's courts judged the vote to be illegal and unconstitutional but the regional Catalan government made a decision to press ahead with it.
Careful not to undermine Rajoy, the European Union has merely called for dialogue between the sides.
Unionists and their supporters took to the streets of Barcelona to protest any moves toward independence as a result of Catalonia's referendum vote, with a number of demonstrators raising their right arms in fascists salutes, according to the Daily Mail.
Earlier, thousands of people rallied across the country for Spanish unity.
In a reflection of the divisions within the pro-unity camp, though, only a few high-ranking members of Spain's leading opposition party, the Socialists, participated, the most prominent being Josep Borrell, a former president of the EU.
Spanish Prime Minister Mariano Rajoy said he would not rule out using constitutional powers to take away Catalonia's autonomous status if the region declares independence.
Three banks as well as gas and water companies have announced plans to move their corporate headquarters out of the region, as Catalonia is plunged into a period of instability.
The ideal would be not to have to take drastic measures. "I would like the threat of an independence declaration to be withdrawn as quickly as possible".
The referendum was accompanied by police violence as they tried to stop the vote from taking place.
When Puigdemont's minister for external affairs, Raul Romeva, was asked by Belgian broadcaster RTBF if the independence declaration would happen, he replied, "Is there an alternative to that?" suggesting Catalan authorities were willing to listen to other options.
"Credibility and dignity suggest making the declaration of independence tomorrow", said Jordi Sanchez, the head of the civil group National Catalonia Assembly said today.
As a result, the two leaders have not been in contact for some time. With its own language and cultural traditions, demands for independence in Catalonia date back centuries but have surged during recent years of economic hardship. It is home to 7.5 million people and accounts for about a fifth of Spain's economy. As Spanish police started seizing ballot boxes, Catalan officials allowed voters to cast ballots wherever they liked.
