The same value-added tax (VAT) rate of 7 percent levied on tickets for theatres, cinemas and amusement parks should be applied to ticket sales and season subscriptions instead of the current 16 percent, LFP president Jose Luis Astiazaran said.
"It is not our intention to bleed money from state coffers but it must be acknowledged that the future of Spanish football could be at risk if we do not take the necessary steps," Astiazaran told a conference in Madrid on Monday night.
"It (the tax reduction) would be a welcome measure which would contribute to promoting sports as well as satisfying the requirements of fiscal equality and neutrality," he added. "Let's find ways that help in this crisis situation."
The LFP's demand is unlikely to find much sympathy with Spain's Socialist government at a time when unemployment has doubled to close to 20 percent and the fiscal deficit swelled to 11.4 percent of gross domestic product (GDP) last year.
A spokesman for the government's sports council (CSD) said on Tuesday any issues relating to professional sport, including sales tax, would be addressed in a new law that would be drawn up once a parliamentary commission had presented recommendations next month.
"There is no concrete stance yet (on the VAT issue) and we'll have to wait for the new law," the spokesman said.
"All our neighbouring countries and leagues have a centralised (TV) marketing system, where the distribution of the income from the exploitation of those rights is determined by law," Astiazaran said.
