Audit-ready. Advisor-grade. Built for what matters.
Turn residency days, supporting records, address consistency, and advisor review into one explainable, audit-ready record.
The move changes the risk
You are 80×more likely to face a residency audit after moving away from a state with meaningful tax revenue at stake.
An estimated ~10–12% of higher-exposure movers may be audited within five years.
The real problem
Travel happens in calendars. Addresses change across dozens of accounts. Evidence arrives monthly. By the time a question is raised, reconstructing the story is expensive and uncertain.
A better operating rhythm
Hammer Domicile makes preparedness a lightweight monthly habit and gives advisors a cleaner place to review the result.
Upload evidence, record travel, and complete state-specific migration tasks.
The Domicile Advisor prioritizes state-specific tasks, proof requirements, stale records, and address inconsistencies.
Invite an advisor and generate an indexed domicile binder for professional review.
Domicile Defense
Capture the evidence already created by your life, reconcile it continuously, and give the right professionals a clean place to review it.
Organize receipts and supporting documents in one searchable evidence library. Automated OCR is being introduced in controlled pilot access.
