Quick Answer
There is no district-only tax break for St. Petersburg’s Innovation District. Businesses there use a mix of incentives:
- City cash grants for new high-wage jobs (Grow Smarter, up to $8,000 per job)
- Florida’s R&D tax credit and sales-tax exemption on R&D equipment
- Florida’s tax baseline: no personal income tax and a 5.5% corporate rate
- Federal Opportunity Zone benefits for qualifying investors, with a new zone map taking effect January 1, 2027
Incentives depend on your industry, wages, exact parcel and entity type, so confirm eligibility before you sign a lease.
What Is St. Pete’s Innovation District?
The Innovation District is a 560-acre district next to downtown St. Petersburg where research institutions, entrepreneurs and community partners work together. It runs roughly from Fifth Avenue South to 18th Avenue South and includes USF St. Petersburg, Bayfront Health, Johns Hopkins All Children’s Hospital, SRI International and the USF College of Marine Science.
Its industry focus is marine science, life science, data and technology, and the arts, along with education and entrepreneurship. The district has about 9,000 employees, and 62.3% of those jobs pay above the median wage. That high-wage profile matters, because most of the incentives below reward above-average pay.
Local Incentives: City of St. Petersburg
Grow Smarter Job Creation and Talent Attraction Grant
This is the most direct cash incentive for small Innovation District employers.
- Who qualifies: Companies with 49 or fewer employees that hire new staff at salaries above the Pinellas County average wage
- Target industries: Marine and Life Sciences, Specialized Manufacturing, Financial Services, Data Analytics, and Creative Arts and Design. These line up closely with the district’s own clusters.
- Base award: $3,000 per new job paying at least 115% of the county average wage, with larger awards for higher wages
- Resident bonuses: An extra $2,000 for each job filled by a St. Petersburg resident, and an extra $3,000 for each job filled by a South St. Petersburg CRA resident
- Maximum: The city’s small business office lists up to $8,000 per new job
- Timing: New hires must stay at least 12 months, and the incentive is paid at the end of that period
South St. Petersburg CRA Programs
The South St. Petersburg Community Redevelopment Area (CRA) is bounded generally by 2nd Avenue North and the interstates on the north, 4th Street South on the east, 30th Avenue South on the south, and 49th Street on the west. Because 4th Street South is the CRA’s eastern edge, Innovation District parcels west of that line may qualify. Parcels east of it, along the waterfront, generally do not. Check by street address.
Inside the CRA, the Microfund Program offers mentoring and networking paired with CRA funding, so owners can make improvements without putting up capital first.
The Greenhouse and the ARK Innovation Center
The Greenhouse, the city’s small business center, runs the city-funded local grant and incentive programs and is the place to start an eligibility check. Early-stage tech founders should also know the ARK Innovation Center, a 45,000-square-foot incubator at 1101 4th St S. inside the Innovation District. To use its programs and offices, companies must be building a scalable tech business.
State Incentives: Florida
Florida’s Baseline Tax Advantages
- No personal income tax. Owners of pass-through businesses (LLCs, S corps) pay no state tax on business income.
- Corporate income tax of 5.5%, with the first $50,000 of taxable income exempt
- No state sales tax on commercial rent. Florida repealed the business rent tax effective October 1, 2025, which lowers occupancy costs for every Innovation District tenant.
Florida Research and Development Tax Credit
For life science, marine science and tech firms, this is the most relevant state credit.
- How it works: The credit is capped at $9 million statewide each year for eligible businesses in target industries that increase their qualified research spending in Florida
- Federal link: A corporation must claim and be allowed the federal research credit under Section 41 of the Internal Revenue Code
- Certification: Only businesses holding a valid FloridaCommerce letter certifying their target-industry status may apply to the Department of Revenue
- Application window: In 2026, qualified target-industry businesses could apply online from March 20 to March 26 for credit on expenses incurred in 2025. Expect a similar short spring window in 2027.
- Proration risk: Requests often exceed the cap. In the Department of Revenue’s own example, a taxpayer requested $700,000 and was allocated $322,000.
- No expansion yet: A 2026 bill to raise the annual cap from $9 million to $50 million died in the Senate Finance and Tax Committee on March 13, 2026.
Because it is a corporate income tax credit, LLCs and partnerships should confirm eligibility with a tax adviser.
Sales Tax Exemption on R&D Equipment
Machinery and equipment used at least 50% of the time for research and development are exempt from Florida sales and use tax. Certification is no longer required for this exemption. The buyer gives the seller a signed affidavit instead. For labs at the district’s research cluster, this can save 6% or more on equipment purchases.
What No Longer Exists
Older guides still cite these programs. Do not count on them:
- Qualified Target Industry (QTI) tax refund. It once paid $3,000 per new job, and St. Pete used it to recruit companies. However, no new businesses could be certified after June 30, 2020. A state program review notes that the 2023 Legislature removed it along with other incentives.
- Enterprise Zones. Florida’s enterprise zone program expired in 2015.
Federal Incentives
Opportunity Zones: A 2026–2027 Transition
The Innovation District’s incubator site was built in a designated Opportunity Zone, and nearby commercial listings still advertise Opportunity Zone status. The program is now changing:
- Permanent program: The One Big Beautiful Bill Act of 2025 made Opportunity Zones permanent and updated their benefits and rules
- New map: New “OZ 2.0” designations run from January 1, 2027, through December 31, 2036. Florida’s governor began submitting nominations July 1, 2026.
- Eligibility is tighter: Stricter income tests for census tracts will significantly reduce the number of zones. A tract in a zone today may not be in one in 2027.
- What it offers: Deferral, reduction and possible elimination of capital gains taxes for investors, not rebates or grants
The key takeaway: Opportunity Zone benefits go to investors who roll capital gains into a Qualified Opportunity Fund, not to the business tenant directly. Startups raising capital can still use OZ status as a pitch to investors.
Federal R&D Credit and Expensing
The federal Section 41 research credit also applies, and it is the gateway to Florida’s state credit. Qualifying small startups can apply part of the federal credit against payroll taxes, which helps pre-revenue companies. The 2025 federal tax law also restored immediate deduction of domestic research costs.

How to Stack Incentives: A 5-Step Checklist
- Confirm your parcel. Check whether the address is in the South St. Petersburg CRA and whether it will be in a 2027 Opportunity Zone.
- Match your industry. Make sure your business fits one of the city’s five Grow Smarter clusters and the state’s target industry list.
- Plan hiring around wage thresholds. Set salaries at or above 115% of the county average wage, and recruit city or CRA residents when possible.
- Track R&D spending from day one. Set up federal Form 6765 documentation and mark the spring Florida R&D credit window.
- Call The Greenhouse before signing a lease. Program funding opens and closes, and some programs require you to apply before you hire.
Frequently Asked Questions
Is there a special tax rate inside the Innovation District?
No. The district is a collaborative economic development area, not a tax district. Incentives come from city, state and federal programs that apply based on industry, wages and location.
Can a two-person startup qualify for incentives?
Yes. Grow Smarter is limited to firms with 49 or fewer employees, so it is built for small companies. The federal payroll tax offset for R&D also targets early-stage firms.
Does Florida still offer the QTI tax refund?
No. New QTI certifications ended in 2020, and the Legislature later repealed the program.
Will Opportunity Zones still apply in the Innovation District in 2027?
That depends on the final OZ 2.0 map, due by the end of 2026. Investors should confirm tract status before committing new capital.
