At Nu, tax efficiency and compliance are not just obligations—they are pillars that support our ability to scale and innovate. As a Tax Specialist, your primary goal will be to ensure the Total Tax Integrity of our operations. You will have a direct impact on the P&L by ensuring that every tax is calculated with pinpoint accuracy, mitigating risks, and ensuring that Nu stays ahead of U.S. tax requirements.

Your role is fundamental to sustaining financial transparency for investors, auditors, and regulatory bodies.

Your day-to-day will be defined by the dynamism of a complex financial operation. Your main challenges and activities will include:

• Full Compliance Cycle: Leading the calculation, accounting, and technical review of federal and state direct taxes (corporate income tax, including federal estimated payments and state apportionment) and also support on the management of indirect taxes (sales & use tax, excise tax, and other transaction-based levies across multiple jurisdictions) compliance managed by local external advisors.
• Tax Filing and Payment Management: Owning the end-to-end calendar of tax filing deadlines and payment obligations across all federal, state, and local jurisdictions including the timely review of estimated tax payments (Form 1120‑W), coordination/submission of extension requests, and final returns. Maintaining a centralized compliance calendar to proactively manage due dates, avoid penalties, and ensure accurate payment amounts are reconciled against the general ledger, along with the support of local external advisors.
• High-Precision Financial Reporting: Preparing and reviewing footnote disclosures for Effective Tax Rate (ETR) reconciliation under ASC 740, as well as managing the movement and projection of deferred tax assets and liabilities, including valuation allowance assessments.
• Mastery of Ancillary Obligations: Guaranteeing the flawless delivery of complex filings such as the federal consolidated return (Form 1120), state and local income tax returns, information returns (Forms 5471, 8858, 8865), and FBAR/FATCA filings, ensuring that all reported data faithfully reflects the underlying accounting reality.
• Stakeholder and Audit Management: Acting as the focal point for federal and state tax examinations and audits (internal and external), defending the company's tax positions before the IRS and state revenue authorities, and maintaining the SOX (Sarbanes‑Oxley Act) control environment.
• Transfer Pricing Coordination: Managing Transfer Pricing workflows in partnership with external advisors, ensuring that intercompany operations comply with OECD guidelines and U.S. Treasury regulations (IRC 482), including the preparation and maintenance of contemporaneous documentation.

To succeed in this role, we are looking for more than just technical knowledge; we need solid experience and a proven track record in high‑rigor environments:

• Experience in Effective Tax Rate Reconciliation: You have directly managed the bridge between book and taxable income under ASC 740, knowing how to explain rate variances, assess uncertain tax positions (ASC 740‑10 / FIN 48), and project deferred tax assets and liabilities for SEC‑reporting or audited companies.
• Experience with Financial Institution Tax Compliance: Specific experience preparing and reviewing tax filings in a regulated financial services environment, including familiarity with bank‑specific tax considerations (e.g., bad debt reserves, OID, original issue discount instruments) and information reporting obligations (Forms 1099, 1042, and FATCA/CRS).
• Background in Internal Controls (SOX): Practical experience designing, executing, and reviewing tax‑related internal controls under a SOX framework, ensuring the end‑to‑end tax process is auditable, well‑documented, and free of material weaknesses or significant deficiencies.
