Their La Liga title win caps off a campaign that also saw them lift two other domestic trophies.
Club president Joan Laporta confirmed that Barcelona can now operate under the 1:1 financial rule, allowing them to reinvest funds directly into player acquisitions.
"Of course we can sign, we're at 1:1 and I hope it continues like this for many years. It's true we were very tight, so now it's time to work," said Laporta, as quoted by SPORT.
"We'll be able to sign. It's always going to be difficult, because the fair play regulations are very, let's say, 'unique'. They're open to interpretation.
"We'll have to keep fighting; it won't be easy, but it will be even better when we achieve it."
An additional boost is expected in May, when revenue from VIP seat sales at the newly redeveloped Spotify Camp Nou will be officially counted. This income could further enhance the club's manoeuvrability in the transfer market.
"They're already in place, yes," Laporta added. "They'll probably be counted this month, but it's worth remembering that La Liga sets the salary cap when it receives our budgets."
