From Tax IDs to Trusted Advisors: How Filing Express Became the Go-To Ally for Global Entrepreneurs
Written by Kaitlyn Gomez
When Sina Bonabi launched a niche tax ID service eight years ago, his mission was straightforward: help foreign entrepreneurs cut through the complexities of U.S. business compliance. That vision laid the foundation for what is now Filing Express, a full-service accounting and advisory firm with a growing global footprint—and a reputation for empowering business owners from startup to scale.
“What began as a solution to navigate red tape has evolved into a complete platform for business formation, strategy, and tax management,” says Brian Cunningham, co-founder and CEO of Filing Express. Today, the company supports thousands of clients worldwide, serving everyone from first-time founders to seasoned operators expanding into the U.S. market.
Trust Built Across Borders
Working with international clients brings unique challenges—chief among them: building trust from a distance. Filing Express has earned that trust through transparency, consistency, and results.The firm has quietly amassed more than 1,000 public reviews with a 4.8-star average, a testament to its client-first approach. Rather than positioning itself as a middleman for the IRS, the company advocates for entrepreneurs—delivering clarity, step-by-step support, and services designed with the client's best interest in mind.
Institutional Expertise, Boutique Service
A major driver of Filing Express’s momentum is its team. Unlike many competitors in the online tax and filing space, this isn’t a group of self-taught professionals. The firm’s advisory staff includes seasoned experts with decades of experience at firms like Ernst & Young, PwC, Deloitte, and Dean Dorton.With over 40 years of combined experience, the team brings institutional-grade expertise typically reserved for enterprise clients—now made accessible to small businesses, e-commerce founders, and international entrepreneurs.
Despite their pedigree, the service model remains highly personal. Filing Express prioritizes white-glove support and concierge-level care, offering fixed pricing, clear communication, and a single point of contact for every client. It’s a rare blend of corporate precision with small-business heart.
One Platform, Every Essential
Filing Express may have started with ITINs and EINs, but today it offers far more. Clients can incorporate a business, open a bank account, file for tax IDs, and get ongoing accounting—all within one streamlined ecosystem. “Entrepreneurs shouldn’t have to juggle five different vendors just to stay compliant,” says Cunningham. “We built Filing Express to eliminate that friction.”From monthly bookkeeping and tax prep to strategic tax planning and CFO-level insights, every product is built with growth in mind. International founders especially benefit from the centralized structure—avoiding the piecemeal approach so many face when launching in the U.S. market.
The firm also supports digital-first operators like e-commerce businesses, online service providers, and remote founders, providing financial visibility and strategic support to scale efficiently from anywhere in the world.
A Challenger on the Rise
Filing Express isn’t competing to be the cheapest provider in the space—it’s competing to be the most trusted.With internal investments in proprietary technology, including a custom CRM platform, the company is built to scale while retaining its high-touch service. It’s a modern challenger brand taking on legacy players like LegalZoom, Liberty Tax, and H&R Block—offering higher value, deeper insight, and more comprehensive support.
Milestones like membership in elite entrepreneurial circles and inclusion in the ClickFunnels Two Comma Club underscore the brand’s upward momentum. Surpassing 10,000 client engagements is just the beginning.
The proof, however, lies in the feedback. One client called their EIN filing experience “flawless… fast, clear, and direct,” echoing hundreds of reviews that consistently praise the platform’s reliability and professionalism.
The Future: From Launchpad to Lifeline
Looking ahead, Filing Express envisions itself as the definitive launchpad for entrepreneurs, small business owners, and investors entering or scaling within the U.S. market.By bundling formation, compliance, accounting, and advisory under one brand, it offers more than just convenience—it delivers confidence. Whether you're a digital founder abroad or a domestic business owner looking for better insight, Filing Express is the trusted ally that not only supports your business but understands the journey.
From its beginnings as a specialized tax ID provider to its current role as a comprehensive advisory firm, Filing Express is a story of evolution done right—scaling without compromising service, and growing without losing sight of what matters most: the client.
In a world of complexity and ambition, having a partner like that isn’t a luxury. It’s a necessity.
