San Francisco Tax Official Tajel Shah Rigged $10 Million Contract, City Audit Finds

A city audit has confirmed what whistleblowers warned about for years: a top San Francisco official rigged a multimillion-dollar contract to benefit a personal friend — and taxpayers footed the bill.

When a government employee can tilt a competitive bidding process in secret, funnel work to a friend’s company, and help place a family member in a related job — all while managing billions in public tax revenue — the question isn’t whether the system failed. The question is how long it was allowed to fail before anyone with authority chose to act.

What Did San Francisco’s Audit Actually Find?

The answer, confirmed in a joint report published June 23 by San Francisco’s controller’s and city attorney’s offices, is damning in its specificity. Tajel Shah, who served as the city’s chief assistant treasurer from 2017 to 2025, systematically manipulated a competitive procurement process to steer a contract worth approximately $7 million — part of a broader roughly $10 million project — toward Mechanical Orchard, a self-described “AI-native technology company” whose then-chief revenue officer, Roque Versace, was a close personal friend.

City auditor Mark de la Rosa concluded that the solicitation process was “compromised by an undisclosed friendship” between Shah and Versace, and that “repeated decisions were made to help the company develop the highest-scoring proposal, even though bidding was supposed to be neutral.” The audit found that Shah abused her position’s authority — and that the office’s own organizational structure made it possible.

A top San Francisco official allegedly moved a contract winner from fifth place to first — by manipulating the scoring sheets herself.

How Did One Official Rig an Entire Bidding Process?

The mechanics of the scheme, as detailed in the audit, were extensive and deliberate. According to the investigation, Shah shared proprietary information with Mechanical Orchard that was unavailable to competing bidders. She failed to require staff to verify the company’s minimum qualifications. She altered the scoring methodology to boost Mechanical Orchard’s ranking. She added fabricated costs to competing proposals to make rival bids appear more expensive than they actually were.

There was also a troubling personal dimension. A subcontractor working alongside Mechanical Orchard, Ratio PBC, subsequently hired Shah’s niece. Auditors found email records showing that Shah personally contacted Ratio PBC’s CEO to thank him for his work on the city project — and then asked whether she could connect him with her family member. The auditors noted that soliciting employment for a relative from a prospective vendor is “inconsistent with the high standard of conduct” required in public procurement. Shah denied wrongdoing; the email trail said otherwise.

$2.6 billion. That is the amount in business tax revenue Shah’s office was responsible for managing. The question San Francisco taxpayers deserve answered: who else knew?

Who Is Really Responsible for Letting This Happen?

Shah did not operate in a vacuum. The audit found that the Office of the Treasurer and Tax Collector had an organizational structure that blocked meaningful oversight, with no checks and balances sufficient to catch — or stop — her behavior. Investigators described Shah’s management style as “largely defined by intimidation.” She controlled not just the procurement process but also the HR team, the very office to which employees would normally report concerns. Staff who saw irregularities had nowhere safe to turn.

City Treasurer Jose Cisneros, who heads the office, requested the independent audit and has since accepted its findings. In his response, he acknowledged that “directing staff to manipulate a competitive procurement process to benefit a personal associate while concealing that relationship was wrong” and that it “violated the city’s ethics and procurement policies.” But the whistleblower complaint filed with San Francisco’s Ethics Commission last year was equally pointed about the treasurer himself: if Cisneros was unaware of Shah’s conduct, the complaint argued, “it reflects a serious failure of oversight.” If he was aware, it raised more troubling questions still.

If a public official can intimidate her own HR department into silence, what other problems in San Francisco’s city hall have never surfaced?

What Do Defenders of the Process Actually Believe?

Some will argue that this case demonstrates the system working as intended: a whistleblower came forward, a reputable media outlet investigated, city officials launched an independent audit, and the guilty party lost her job. That is not nothing. San Francisco does have whistleblower protections, and in this case they held. The city controller’s office and city attorney moved decisively once the matter was public, and the treasurer ultimately accepted the audit’s conclusions without legal resistance.

It is also fair to note that Mechanical Orchard walked away from the contract the day before The SF Standard first published its investigation — meaning the vendor did not ultimately profit from the corrupted process. The full contract was never executed.

These are legitimate points. But they do not answer the more uncomfortable question: the scheme ran for more than two years, involved over 1,100 documented emails and internal communications, touched multiple layers of city government, and resulted in a tainted process that cost taxpayers the time and resources spent on a procurement they must now restart from zero. A system that only corrects corruption after a journalist files public records requests is not a system in control of itself.

Is Anyone Actually Facing Consequences?

Shah left city employment on November 21, 2025. Roque Versace departed Mechanical Orchard in January 2025 and relocated to London. The original contract has been voided. The city says it will restart the procurement process for the business tax software — the technology that manages tax collection for roughly 90,000 San Francisco businesses — from scratch, with “proper procedures in place.”

What is conspicuously absent from every official statement so far: any mention of criminal referral. Bid-rigging on a government contract, manipulation of procurement scoring, and nepotistic job placement with a vendor are not merely administrative failures. They are the kind of conduct that, in other jurisdictions, triggers federal fraud investigations. San Francisco’s city attorney has been involved in the investigation. Whether that involvement extends to any referral to state or federal prosecutors has not been publicly stated.

If the only consequence for rigging a multimillion-dollar government contract is quietly leaving your job — what exactly is the deterrent?

What Happens to San Francisco’s Business Tax System Now?

The urgency here is not abstract. The technology the city currently uses to process business taxes for tens of thousands of businesses is aging and could become inoperable within a few years, Treasurer Cisneros has acknowledged. The failed procurement was intended to replace that system. Now the city must go back to the start of a contracting process that could take months or years to complete — while the clock on the existing system continues to run.

The city says it is committed to restarting with transparency and fairness. The office has also reorganized its leadership structure, though the specifics of those changes have not been detailed publicly. San Francisco Controller Greg Wagner was direct in his assessment: “Preventing bias, favoritism, and the misuse of public funds requires every individual to recognize their ethical responsibility to speak up against wrongdoing — and that needs to happen in an environment where transparency and collective accountability are non-negotiable.”

Fine words. The harder test is whether those words are backed by structural reforms that make the next Tajel Shah impossible — not just harder to catch after two years.

Key Questions

• Will San Francisco’s city attorney or any federal authority pursue criminal charges against Shah for bid manipulation and potential procurement fraud, or does this case end with a quiet departure and no legal accountability?
• Who else in the Office of the Treasurer and Tax Collector was aware of Shah’s conduct, and will the reorganization of leadership include any accountability for supervisors who failed to act?
• How long will it take to restart the business tax software procurement, and what is the contingency plan if the existing system fails before a replacement contract is in place?

The real question here is not whether San Francisco had a corruption problem — the audit confirmed that it did. The real question is whether the city has the institutional will to ensure that the next official who tries to rig a contract for a friend faces something more serious than a severance package and an early exit.
