AUTOMATIC RESIDENCY DAY COUNTING

Prove where you were.

One day too many in the wrong state can make you its tax resident — and the burden of proof is on you. SpyglassBeacon counts your days in every state automatically, warns you before you cross the 183-day threshold, and keeps the audit-ready record.

WHO IT'S FOR

Snowbirds & state movers. Splitting the year between two states? The count decides which one taxes your income.

Florida, Texas & Puerto Rico relocators. Moving to a no-tax state only works if you can prove 183 days. Beacon is your evidence.

Remote workers. Work from anywhere — without accidentally becoming a resident of somewhere expensive.

Anyone facing an audit. New York alone runs thousands of residency audits a year. The day count is the whole case.

PRIVATE BY ARCHITECTURE

Your location history never leaves your phone.

Beacon stores your day ledger on your device — there is no account, no cloud copy, and nothing for us to sell or lose. The only thing that ever leaves your phone is a report you choose to share.
