What Interstate Tax Services does
Interstate Tax Service, Inc. (ITS) is a Pennsylvania-based, family-owned consulting firm founded in 1943 by Paul C. Moomaw, who as chairman of the PA House Labor and Industry Committee helped draft the state's Unemployment Compensation (UC) Law. The firm provides specialized unemployment compensation consulting services to employers, including claim analysis and recording, monthly audit of UC charges and credits, eligibility appeals, hearing representation before the Department of Labor & Industry, UC contribution rate analysis and appeals, merger and acquisition tax-rate review, relief-from-charge filings, fraud reporting, and educational seminars. ITS operates on a subscription-style recurring consulting fee model, billed per the scope of UC management provided to each employer, and does not publicly disclose pricing.
ITS represents approximately 1,900 clients across three primary segments: private industry employers (the core), non-profit organizations (including healthcare providers), and municipal sub-divisions. Distribution is direct and consultative — primarily through sales-driven engagement by the executive team, free consultations, and referral partnerships with Pennsylvania professional associations such as the PA Chamber, PSBA, PASBO, PASPA, and PSATS. The firm delivers services remotely via phone, email, and online forms, and in-person at UC hearings. ITS is explicitly a professional services firm rather than a technology company: there are no software products, no apps, and no AI-driven automation of its core audit and hearing-preparation workflow.
The company's competitive position rests on regulatory authorship, multi-generational expertise in PA UC law, and embedded relationships with employer HR and payroll teams that treat ITS as an extension of their internal HR function. The firm remains privately held under four generations of family ownership, with no disclosed outside capital, no parent company, and no recent M&A activity. Geographic reach has expanded from a Pennsylvania base to multi-state employer representation across the United States.

Interstate Tax Services competitors and assessment
Company assessmentEmerging players
- Gusto: Gusto is a fast-growing SMB payroll, benefits, and HR platform that includes tax services. As an emerging player expanding into HR advisory workflows, it represents the modern digital-first payroll/HR stack competing against traditional consulting-led providers like ITS.
- Trusaic: Trusaic is a tech-enabled provider of unemployment tax management and pay equity solutions for employers. It represents the emerging technology-driven approach to UC cost optimization that competes with traditional consulting firms like ITS on employer tax rate analysis and compliance.
Broad incumbents
- Workday: Workday is an enterprise cloud platform for HR, payroll, and workforce management. As enterprise HR suites absorb tax and compliance functions, Workday represents the structural direction of the HR/payroll market that ITS's manual specialized services must contend with at the high end of the employer market.
- Equifax Workforce Solutions (formerly TALX): Equifax Workforce Solutions (acquired from TALX) provides unemployment cost management, tax services, and employment verification to large employers. It is the closest broad incumbent competitor to ITS in dedicated UC tax management and claims services at enterprise scale.
- Paychex: Paychex is a major payroll and HR solutions provider serving SMB and mid-market employers with tax filing, payroll processing, and HR services. It is a broad incumbent whose payroll/tax service suite competes for the same employer wallet ITS targets through HR outsourcing decisions.
- ADP (Unemployment Cost Management): ADP offers unemployment claims management and tax services as part of its broader payroll/HR suite. It is a broad incumbent serving employers nationwide with overlapping UC claim administration, though specialized UC consulting and hearing representation is not its core focus.
- OneDigital: OneDigital is an insurance and HR consulting brokerage offering employer-side HR advisory, payroll, and benefits services. While not a UC consulting pure-play, it competes for HR and payroll outsourced services that overlap with ITS's relationship-based employer consulting model.
Others
- Thomson Reuters (Tax & Compliance): Thomson Reuters provides tax, payroll, and regulatory compliance software and services used by employers and tax professionals. It serves as adjacent enabling technology and content infrastructure for the broader employment tax and regulatory compliance market in which ITS operates.
Direct peers
- UniTax (Unemployment Tax Services): UniTax is a regional UC tax services firm serving employers with unemployment cost management, claims administration, and consulting. It is a direct niche competitor to ITS in the dedicated employer-side UC consulting category, with similar consulting-led business model.
- Employers' Council: Employers' Council is a non-profit employer association providing HR consulting, training, and compliance support including unemployment claims assistance to member employers. Similar direct consulting model focused on employer-side HR and compliance services, comparable in mission though broader in scope.
