Corporate leaders have reason to be worried. Manufacturing shrank the most in almost four years in October after the Italian economy failed to grow in the third quarter, and unemployment jumped back above 10 per cent in September, 2 percentage points above the euro-area average.
The European Commission now forecasts that Italy will have the slowest growth rate in the 19-nation euro area in 2019 and 2020.
"I'm disappointed and worried, and this feeling is common among entrepreneurs," said Giorgio Xoccato, owner of clothing company Xacus, based in the northeastern region of Veneto. "The government doesn't seem to care about the business community - it's unclear where the resources to cover costs will be found and how it can boost growth."
The dissent is loudest in regions where the League's pro-business, low-tax message resonated the most during the March national elections.
The League, led by Deputy Prime Minister Matteo Salvini, dominated the vote in the north, an arc stretching across the country from the auto-making center of Turin to the financial capital of Milan, to the entrepreneurial stronghold of Veneto.
While the League continues to surge in opinion polls - it's now Italy's top party based on the most recent data - an index of confidence in the coalition led by Prime Minister Giuseppe Conte fell to a record low in November, according to an SWG poll for TG LA7.
The main cause of voter angst: next year's proposed budget, a precarious compromise between the League and the leftist Five Star. "La manovra," as the budget is known, is viewed negatively by 60 per cent of the League's base in the wealthy northeast, according to a Demos & Pi poll for daily la Repubblica.
The budget sparked "a sharp change in expectations among local entrepreneurs due to uncertainty brought in by the new government and measures they've announced," said Luciano Vescovi, head of industry association Confindustria for Vicenza, a city 80 kilometers (50 miles) east of Venice.
And no item in the budget splits voters - and the coalition - more than the so-called citizen's income, a plan to distribute funds to poorer Italians that was a key plank in Five Star's electoral platform.
Five Star leader and Deputy Prime Minister Luigi Di Maio warned that the government could be at risk after a top League lawmaker said implementing the policy as planned would be "complicated."
The push and pull between the coalition members and the lack of clarity on what the economy will look like in 2019 is making businesses hesitant to invest.
"If you're not confident what the future brings, you slow down investments in your business," said Vescovi, who runs a a family construction company. "We're worried about public debt and the relationship with Europe, this budget seems designed to pick a fight."
Concerns among institutional investors appear to match what business people are saying. Since Five Star and the League started talks to form a government in early May, Italy's benchmark FTSE MIB index has lost more than 20 per cent, entering into a so-called bear market.
In the same period, the yield spread between benchmark 10-year Italian government bond and their German counterparts has more than doubled.
In industrial centers like Turin, home of Fiat Chrysler, apprehension about the budget's effects on the economy have mixed with anger over Five Star-driven policies that don't sit well with local businesses.
After Turin's Five Star-led city government voted to try to block works on the TAV high-speed rail link with France, businesses teamed up with unions to protest. The League fanned the flames, making no secret of its support for TAV, even after Five Star reiterated its opposition.
"Adesso Basta," a Turin business group whose name translates roughly as "Enough Already," has called for a mass march November 10 to protest. "Unsustainable, paradoxical, absurd and dangerous," the organisation's leader Corrado Alberto said in describing the government's current direction.
