Pennsylvania has a problem — and it's bigger than most people realize.
The state's Independent Fiscal Office projects Pennsylvania's structural deficit will expand to $6.8 billion in fiscal year 2026-27 — even after accounting for new revenue proposals in Governor Shapiro's budget.
Pennsylvania is on track to spend more than it brings in this fiscal year. Governor Shapiro proposed spending $4.3 billion more than the state is projected to raise in revenue — part of a $53.2 billion budget proposal.
And there's a hard deadline: Pennsylvania's budget must be approved by June 30 or the state government faces a funding crisis. WTHR
Something has to give. And sales tax is one of the most likely levers lawmakers will reach for.
Before diving into what could change, it helps to understand where Pennsylvania stands.
Pennsylvania has a 6% statewide sales tax rate and an average combined state and local sales tax rate of 6.34%. Only Allegheny County and Philadelphia are permitted to add local sales taxes on top of the state rate. TaxJar
Pennsylvania raises tax revenue primarily through individual income taxes — 26.3% of total state and local revenue — property taxes at 25.7%, and other taxes at 22.3%. TaxJar
Critically, Pennsylvania taxes certain services that are specifically enumerated by law — but most services are exempt unless the legislature has explicitly named them as taxable. That means a vast portion of the modern service economy — legal services, accounting, consulting, marketing, personal care, home repair — currently escapes Pennsylvania's sales tax entirely. TaxCloud
That's the gap lawmakers are increasingly eyeing.
The scale of Pennsylvania's fiscal challenge is hard to overstate.
The IFO projects that Governor Shapiro's revenue proposals — including marijuana legalization, skill games taxation, and other new initiatives — would generate $652 million in fiscal year 2026-27 and $1.76 billion by fiscal year 2030-31. Despite all of that new revenue, a $6.8 billion deficit remains by the end of the period. Fox 59
In other words: the revenue proposals already on the table don't come close to closing the gap. And even without increasing spending over this year — an impossible feat given growing Medicaid obligations — Pennsylvania would still be poised to spend $1.2 billion more than it brings in next fiscal year.

Senate Republicans, who control the chamber, have been blunt. Senate President Pro Tempore Kim Ward said the IFO's findings point toward "massive, broad-base tax increases" as the only viable path forward if spending isn't dramatically curtailed. WTHR
When states face structural deficits of this magnitude, they have three options: cut spending, raise existing tax rates, or broaden the tax base. Pennsylvania has already tried the first two — and neither has solved the underlying problem.
Broadening the sales tax base — specifically by adding services that are currently exempt — is the option that generates the most revenue without raising the headline rate that voters and businesses immediately feel. Pennsylvania's Independent Fiscal Office has already determined exactly how much revenue the state could bring in by taxing a variety of currently exempt products and services — and the numbers are significant.

This isn't a new conversation in Harrisburg. Pennsylvania has debated service taxation for decades. What's different in 2026 is the size of the deficit, the tightness of the budget deadline, and the fact that neighboring states have already moved in this direction.
One specific piece of the sales tax puzzle is drawing serious attention in Pennsylvania right now.
The Shapiro administration's latest budget estimates show Pennsylvania could lose out on about $2 billion in sales tax revenue by mid-2031 due to a tax break for data centers — a figure that has grown dramatically from an original estimate of $89 million for fiscal year 2026-27.
The trajectory is familiar: Pennsylvania created a modest data center sales tax exemption in 2016, lawmakers removed the cap in 2021, and the exemption has exploded far beyond any original projection as the AI and cloud computing boom drove massive data center investment into the state.
State Representative Greg Vitali introduced a bill to repeal the exemption entirely, singling out Amazon and Microsoft as companies that don't need the break. But he told reporters he's uncertain the measure will clear the House, let alone the Senate and the governor's desk.
Data center developers and their supporters argue the sales tax exemption has enabled growth that employs thousands of construction workers and generates billions in economic activity — and that Pennsylvania's proximity to large population centers, plentiful electricity, available land, and skilled workforce are what attract development, not just the tax break.

Sound familiar? It's the same argument playing out in Virginia — only Pennsylvania's deficit numbers make the pressure to act even more acute.
There's another sales tax development in Pennsylvania's budget fight that businesses and consumers should know about.
Governor Shapiro proposed diverting an additional 1.75% of sales and use tax revenue — equivalent to $319.6 million — to fund public transit agencies including SEPTA and Pittsburgh Regional Transit. Indiana Capital Chronicle

The political debate over this proposal is fierce. Supporters say SEPTA and Pittsburgh Regional Transit are in genuine crisis and need the funding. Critics argue that diverting sales tax revenue from the General Fund deepens the deficit problem rather than solving it — robbing one hole to patch another.
For businesses, the practical implication is this: if the General Fund loses $319.6 million in sales tax revenue to transit, something else has to replace it. That pressure flows directly back to the base-broadening conversation.
If Pennsylvania follows the path other states have taken — and the budget math suggests it may have no choice — the services most likely to enter the taxable column include:
The key constraint is political, not fiscal. Pennsylvania currently taxes only services that are specifically enumerated by statute. Adding new service categories requires explicit legislative action — which means every affected industry will lobby hard against inclusion, and every lobbyist in Harrisburg will be working overtime between now and June 30.

This is the part that makes 2026 different from prior Pennsylvania budget fights.
Pennsylvania has a history of budget impasses. Last year, lawmakers couldn't agree on a state budget for months — leading to a bitter standoff and negotiations stretching into November while schools and counties went unfunded. This year, both Governor Shapiro and legislative leaders have publicly committed to avoiding a repeat.
Both Senate and House leaders acknowledged the tough fiscal realities and said the first negotiations were a good first step in opening talks much earlier than last year. WTHR
June 30 is six weeks away. Whatever Pennsylvania's legislature decides about sales tax — base broadening, service taxation, the data center exemption, the transit diversion — it needs to happen by then.
For businesses operating in Pennsylvania, the window to understand your exposure before the rules change is short.
If you operate a service business in Pennsylvania that is currently exempt from sales tax, 2026 is the year to take that exemption seriously — because it may not survive the budget process.
The practical checklist:
Pennsylvania isn't the only state in this position. But the size of its deficit, the tightness of its deadline, and the groundwork already laid by the IFO make it one of the most likely states to act on sales tax expansion in 2026.
