Nishijima Accounting & Tax

What Nishijima Accounting & Tax does

Nishijima Accounting & Tax, LLC is a privately held CPA firm headquartered in Schaumburg, Illinois (Chicago suburb), founded in 1988 and operating under its current name since 2001. The firm provides a bundled suite of professional accounting, tax, payroll, and consulting services to small and medium-sized businesses in the US Midwest, with a deliberate niche focus on Japanese companies operating US subsidiaries and Japanese expatriate individuals. Its service portfolio comprises five integrated offerings: accounting (year-end, monthly/quarterly closing, and bookkeeping), tax (corporate, individual 1040, sales tax, non-profit, and expatriate-specific filings including ITIN and FATCA), payroll (including gross-up calculations for guaranteed net pay arrangements), accounting software implementation and migration support for QuickBooks and Sage 50, and general accounting/tax consulting that includes cross-border business expansion advisory.

The firm is led by Setsuko Nishijima, a US CPA and member of the AICPA and Illinois CPA Society who joined from Deloitte Touche Tohmatsu's audit department in 1996 and assumed ownership in 2001. Service delivery is bilingual (English/Japanese) and is offered both on-site at client locations and remotely, accommodating clients across the Midwest and beyond. The firm's technology stack is built around third-party accounting platforms rather than proprietary systems, and it derives no disclosed revenue, scale metrics, or institutional investment.

Revenue mechanics are entirely fee-based, with customized quote-based pricing per engagement and monthly billing cadence typical of professional services firms. Customer acquisition is primarily through referrals and direct outreach to the Japanese business community in the Midwest. The firm operates from a single office with no disclosed subsidiaries, partnerships, or affiliations, and has posted hiring listings indicating incremental capacity expansion.

Broad incumbents

• HLB USA: US member of HLB International, an accounting and advisory network with deep Japan roots and significant cross-border Japanese client work. Comparable target customer base (Japanese companies operating in the US) and similar accounting/tax/consulting service mix.
• EisnerAmper: Mid-tier US accounting and advisory firm with international and Japanese client services. Competes for the same Japanese SMB and mid-market tax/accounting engagements, especially in the Midwest and East Coast, with a broader service portfolio.
• Withum: Top-30 US accounting firm with international tax and advisory capabilities serving foreign-owned US subsidiaries. Comparable in targeting internationally-affiliated SMBs needing bilingual or cross-border tax support, though not Japanese-specialized.
• BDO USA: Top-10 US accounting firm with a dedicated Japanese Business Group serving Japanese-owned subsidiaries in the US. Competes for the same Japanese-affiliated SMB and mid-market clients as Nishijima, particularly in manufacturing and distribution, but at a much larger scale.
• Marks Paneth: US accounting and advisory firm with an international practice serving foreign-owned US businesses. Comparable in providing accounting, tax, and advisory to internationally-affiliated SMBs, including Japanese-owned operations.
• PKF O'Connor Davies: US accounting and advisory firm with international tax and cross-border services for foreign-owned US operations. Comparable in serving SMB subsidiaries of foreign parents with compliance, bookkeeping, and tax work, including in the Midwest.
• Deloitte US: Big-4 firm with a US-Japan Services Group serving Japanese clients across the US. Overlaps directly with Nishijima's Japanese parent/subsidiary tax, expatriate, and audit-adjacent services — and notably is the former employer of the firm's principal.
• CohnReznick: Top-20 US advisory and accounting firm with international tax services for inbound foreign investment. Overlaps with Nishijima on US tax compliance for foreign-owned subsidiaries and expatriate tax work, though at a larger scale and broader industry footprint.
• KPMG US: Big-4 firm with a long-standing Japanese Practice advising Japanese companies operating in the US. Targets the same Japanese parent/subsidiary tax and accounting work, competing especially for larger subsidiaries that may eventually outgrow a boutique provider like Nishijima.
• EY US: Big-4 firm with a Japan Business Services practice addressing accounting, tax, and advisory needs of Japanese-owned US operations. Comparable in target market (Japanese-affiliated entities) and in offering tax compliance and advisory services, but at enterprise scale.
