Building at Check

At Check, we make paying people simple. We’re not just building our own business—we’re building payroll businesses together with every one of our partners. As the inventors of embedded payroll, we’re redefining how people get paid and making it easier for payroll businesses to launch, grow, and thrive.

Check is far more than just API infrastructure. We’re a springboard for building and scaling payroll businesses.

Payroll is broken. Come fix it alongside a team that’s as passionate as you are. At Check, you'll use creative problem-solving, critical thinking, and grit to impact every business we build. We view problems to solve and jobs to be done as opportunities to contribute to the solution; we ignore conventional role boundaries in favor of the unique strengths and value each builder brings to our team and to our mission.

Join us if you’re ready to roll up your sleeves and redefine payroll. Let’s simplify the complex, make a real impact, and create a better future for businesses of every size.

At Check, we make paying and filing taxes seamless, enabling our partners to build best‑in‑class payroll businesses. As a Tax Support Specialist
, you own a portfolio of tax agencies from end to end — you are the person who knows them, handles what comes in from them, communicates on their behalf to partners, and gets resolution across the finish line.

This role will own end‑to‑end tax workflows. When a tax notice is received, a filing needs completed, or a partner has a tax question they can’t untangle, it ends with you. You build fluency with your agencies, their quirks, their timelines, their preferred escalation paths and use that knowledge to drive fast, accurate outcomes for the partners who depend on us.

• Own a defined set of federal, state, and local tax agencies end‑to‑end, including notice resolution, correspondence, corrections, and ongoing compliance across your portfolio
• Be the direct point of contact with agencies: picking up the phone, navigating agency processes, and following through until issues are fully resolved
• Communicate directly with partners about what’s happening with their notices or tax accounts — translating complex agency interactions into clear, honest updates
• Balance and reconcile tax accounts within your agency portfolio, surfacing discrepancies and driving resolution
• Manage a queue of tax issues across your agencies, balancing urgency and complexity without losing track of what’s open
• Recognize when patterns in your portfolio point to a larger systemic issue and bring that signal to the right people

• 3–5 years of experience in payroll tax, tax operations, compliance, or notice resolution — with meaningful exposure to both agency communication and operational/filing work
• Genuine comfort on the phone with tax agencies and in writing to partners — you’re clear, professional, and don’t over‑promise
• Experience with federal (IRS/SSA), state, and local agencies; ability to research and navigate unfamiliar ones when they come up
• Organized and methodical — you can carry a portfolio of open issues across multiple agencies without things slipping
• You solve first, escalated thoughtfully, and own outcomes through to completion
• A curiosity for the edge cases; unfamiliar notice types feel like puzzles, not blockers
