NexusDeduct

NexusDeduct is a web + mobile companion that helps individuals accurately handle state and local tax (SALT) details that generic tax prep often glosses over: multi-state work, partial-year residency, local wage taxes, and city/county credits. Users connect payroll (W-2), bank/credit card, and address history to build a timeline of where they lived and worked. The app flags likely filing obligations, estimates resident vs nonresident allocation, and generates an audit-ready “evidence packet” (dates, paystubs, employer location, commuting days, lease/mortgage, utility proofs). It also tracks local tax rates by municipality and warns when withholding doesn’t match expected liability. This is not a full tax-filing replacement; it’s a SALT accuracy layer that exports clean summaries and attachments to TurboTax/CPA workflows. It’s realistic: the value is in reducing missed credits and avoiding nasty state notices, not magically eliminating taxes.
