Nawrocki signed the bill into law after parliament approved the financial plan in a final vote earlier this month.
Under the law, Poland's budget deficit is expected to be no more than PLN 271.7 billion (EUR 64.5 billion, USD 75 billion) this year, and the target for the general government deficit is 6.5 percent of GDP.
Government revenue is expected to total PLN 647.2 billion in 2026, with spending set at PLN 918.9 billion, Polish state news agency PAP reported.
Officials said the budget fully funds the government’s main social initiatives, including the "Family 800-plus" child benefit programme.
Meanwhile, health spending is expected to total PLN 247.8 billion, and defence spending is expected to reach PLN 200 billion, standing at 4.81 percent of GDP.
'Budget of unfulfilled campaign promises': president
In a video statement, Nawrocki said he had signed the budget into force but would also refer it to the Constitutional Tribunal to assess its compliance with the constitution.
He criticised the government’s financial plan as reflecting "a deep crisis of credibility, effectiveness and agency" in Prime Minister Donald Tusk's Cabinet.
He described the budget as one of "unfulfilled campaign promises and dashed expectations of the Polish people."
“Despite my critical assessment of this budget, the Constitution does not give me the right to veto it," Nawrocki said. "Considering all the arguments and the powers I possess, I have decided to sign the budget bill while submitting it for review by the Constitutional Tribunal."
'Political theatrics': finance minister
Finance and Economy Minister Andrzej Domański dismissed Nawrocki’s decision to refer the law to the Constitutional Tribunal as "political theatrics with no real consequences.
He described the government’s financial plan as "a budget of investment and record defence spending."
'Everything is under control': PM
Prime Minister Donald Tusk has said this year’s budget will deliver "the largest army, the fastest economic growth, the biggest investment projects, an end to high prices and low unemployment."
He acknowledged this would "come at the cost of a high deficit" but told reporters that "everything is under control."

Finance and Economy Minister Andrzej Domański has defended the plan as “a budget of security, investment and support for citizens.”
Tusk has said the budget will fund the country’s largest-ever military, major investment projects and fast economic growth, while keeping inflation down and unemployment low. He acknowledged the plans would come “at the cost of a high deficit,” but said the situation was “under control.”
