What “tax home” means to the IRS
Your tax home is not determined by:
- Who owns the property
- Where your mail is sent
- Where your driver’s license is issued (by itself)
Instead, under IRS rules, your tax home is generally:
The entire city or general area of your main place of business or employment, regardless of where you maintain your family home.
When your parents’ address can be your tax home
Your parents’ address may qualify as your tax home if all of the following are true:
- You regularly live at your parents’ home
- Your principal place of business or employment is in the same area
- Your employment there is indefinite, not temporary
- You have strong ties to that location (banking, voter registration, medical providers, etc.)
In this case:
- You do not need to own property
- Renting or living with family is acceptable
When your parents’ address cannot be your tax home
Your parents’ address is not your tax home if:
- You live and work primarily in another city
- You only use your parents’ address for mail or legal documents
- You are a traveling worker who does not actually live there
- You maintain no meaningful personal or economic ties to that area
In those cases, your tax home is:
- Your main work location, or
- If no regular work location exists, the IRS may treat you as itinerant (no tax home)
Special rule: Temporary vs. indefinite work
This distinction is critical:
- Temporary assignment (generally ≤ 1 year):
- Your tax home remains where you normally live
- Indefinite or long-term assignment (> 1 year or expected to last):
- Your tax home shifts to the new work location
Why this matters
Your tax home affects:
- Travel expense deductions
- Per diem eligibility
- State tax residency analysis
Incorrectly claiming a tax home can lead to:
- Disallowed deductions
- Penalties and interest
Summary
- You do not need to own property to have a tax home
- Your parents’ address qualifies only if it’s your real base of life and work
- Mailing address ≠ tax home
