02 · The problem

What happens when a state challenges your residency.

States with high income taxes — New York and California in particular — have dedicated residency audit units.

A residency audit can take years and cost tens of thousands in legal fees — before any tax liability.

A day-by-day record can help your advisor review your travel alongside receipts, calendars, and other supporting documents.

I

Day counts

How many days did you spend in each state? The burden of proof is on you.

II

Primary residence indicators

Where is your home? Where do you vote? Where is your doctor?

III

Financial ties

Where are your bank accounts, business operations, and club memberships?

IV

Near-vs-far analysis

New York uses a "near and far" test weighing time, business, family, possessions, and social connections.

03 · The product

“Can I take this trip?”

Your friend invites you to a week in the Hamptons. Open Southbound. One number tells you if you can go.

II

Smart alerts

Get notified when your departure budget is running low. Never accidentally overstay a trip and lose your residency claim.

III

Plan with confidence

See exactly how many travel days you have left. No mental math, no spreadsheets, no guessing at year-end.

Workflow · four steps

1

Enable location access

Grant "Always Allow" during setup. Low-power monitoring, not continuous GPS.

2

Go about your life

Your phone detects meaningful location changes. Southbound checks the Florida boundary.

3

Review your record

Running day count, calendar view, and projection toward 183.

4

Export when needed

Date-by-date report with confidence levels. Share with your CPA.

04 · Who it's for

Built for people with something at stake.

You split your time between states. Keep a clear record of where you were, then review your residency obligations with your advisor.

01

Relocating from a high-tax state

Changed your domicile to Florida but still own property or have ties in NY, CA, NJ, CT. Those states are aggressive about residency audits — you need documentation that holds up.

02

Splitting time between two homes

Winter in Florida, summer elsewhere. Keep both trips in one record and plan against the day goal you choose.

03

Working with a tax advisor

Your CPA told you to keep a log. Southbound replaces the spreadsheet you never update. Export a clean report whenever they ask.

04

You are a tax advisor

If you advise HNW clients on state tax residency, Southbound is the tool you wish they had. See the advisor page →

Your location record. Under your control.

01

Seamless backup

With iCloud sync enabled, successfully synced records can return on another device using the same Apple ID. Check sync before replacing your phone.

02

No location database on our servers

You do not create a Southbound account. We do not maintain a server copy of your location history. See our privacy policy for other data processing.

03

Personal iCloud sync

Apple manages the security of your personal iCloud account. Keep your devices and account protected, and review your sync settings in the app.

FAQ

Frequently asked questions.

What is the 183-day rule?

There is no universal 183-day test for Florida residency. Day-count rules and domicile requirements vary by state. Southbound tracks your chosen day goal; it does not determine your tax residency. Ask your advisor which rules apply to you.

How does the tracking work?

Southbound does not use GPS. It monitors cell tower and Wi-Fi network changes — the same low-power system Apple uses for Find My. When your phone detects a meaningful location shift, Southbound checks whether you're inside the Florida state boundary and records the result locally. Most users see zero measurable battery impact.

Is my location data private?

Your location history stays on your iPhone and your personal iCloud account when sync is enabled. Southbound does not receive that history. Apple and RevenueCat process purchase information. You choose where exported reports go. See our privacy policy for details.

What happens if I lose my phone or get a new one?

With iCloud sync enabled, successfully synced records can return on a device using the same Apple ID. Records that have not synced may be lost. Check sync before changing devices.

Will this hold up in an audit?

Southbound helps organize your day records for review alongside other evidence. No app can guarantee that a tax authority will accept a report or agree with a residency claim. Work with a qualified tax advisor.

What does the report include?

The current app exports a date-by-date CSV with day status, confidence, and manual changes. Formatted PDF reports are coming in version 1.2. Preview the actual 15-page report with fictional records.

What does it cost?

Original downloads before September 15, 2026 (midnight Eastern) keep every feature free for life. New downloads from September 15: US $249.99/year, billed annually through the App Store. Eligible subscribers receive a 14-day free trial. The subscription renews automatically unless canceled. Regional prices appear in the App Store.
