FOR ENROLLED AGENTS & BOOKKEEPERS

Stop chasing clients for day counts they never kept

Every spring the same email goes out: "How many days were you in New York? What date did you actually move? How many US days the last three years?" And the same guesses come back. SpyglassBeacon replaces the guesses with an automatic, timestamped per-state and per-country day ledger the client exports in one tap.

Where it plugs into your workflow

Part-year and nonresident returns. Move dates and per-state day splits from the record instead of recollection.
Form 8840 and the SPT. Snowbird clients bring the actual US day counts for the three-year weighted test, not an estimate rounded to the month.
Form 2555 physical presence. Expat clients arrive with the foreign-day count and the travel schedule the form asks for.
Notices and exams. When a state questions residency, the client already holds a contemporaneous day-by-day record, the evidence class examiners actually credit.

What arrives in the file

A PDF: per-state counts against the 183-day standard, international clocks (Schengen, UK tax year, FEIE 330) when relevant, and a day-by-day appendix with timestamps and record counts. Days the client marks as travel-through are struck and labeled rather than deleted, so the record stays complete. Counting uses the any-part-of-a-day standard, and the caveats are printed on the report so nobody over-claims precision.

The practical details

$29.99 a year per client after a 14-day free trial, iPhone only for now, no account to administer, and the location history never leaves the client's phone: you receive documents, not data feeds. Recommending it costs you nothing and saves the day-count email thread every filing season.

Frequently asked questions

Updated 2026-08-26

Can my client export a report I can actually use?

Yes: a PDF with per-state day counts, any international clocks that apply, and a timestamped day-by-day appendix. It is designed to drop into workpapers next to the return.

Does it compute the Substantial Presence Test?

The app counts the US days per year, which is the input the SPT needs; the free SPT calculator on this site runs the three-year weighted arithmetic. The 8840 closer-connection calculator pairs with it for snowbird clients.

Do I get access to the client's data?

No. History stays on the client's device with no account and no cloud copy. Clients export and send reports themselves, like any other document you request.

What does it cost the client?

Free for 14 days with no card, then $29.99 per year through the App Store.

One less email thread every March

Clients bring the day count with them, exported from a record kept all year.
