If you file late
We could not source a late-filing path for Cobb County. No Cobb-official page found stating explicitly what happens to a late application (i.e., whether it rolls to next year); this is the general Georgia norm but was not stated verbatim on a Cobb page in the pages reached. That is not the same as there being no remedy — ask Cobb County Tax Commissioner's Office, Property Tax Division before assuming the year is lost.
Do you have to re-apply each year?
No — once granted it continues while you own and occupy the home. Moving ends it, and the new home needs its own application.

What gets Cobb County applications rejected
Unlike everything above, this list carries no source. It is our own reading of what this county's material emphasises, written to be useful rather than authoritative — treat it as a checklist, not as Cobb County Tax Commissioner's Office, Property Tax Division's rules.
- Filing with the Board of Assessors (assessor.cobbcounty.gov) instead of the Tax Commissioner's Property Tax Division, which is the office that actually processes Cobb homestead applications
- Assuming the county homestead exemption automatically covers a city (e.g., Marietta, Smyrna) exemption, when city exemptions require a separate filing with the municipal tax office
- Not submitting the Age-65 Income Affidavit alongside the base application when claiming the state senior exemption, since it requires separate income documentation
- Not re-filing after a name change from marriage, death, or divorce even though most Cobb exemptions otherwise carry forward automatically
- Relying on the older cobbtax.org or cobbassessor.org domain names instead of the current cobbtax.gov and assessor.cobbcounty.gov sites, which can lead to outdated cached information
Cobb County homestead exemption questions
- When is the homestead exemption deadline in Cobb County?
- April 1 — Cobb County Tax Commissioner's Office, Property Tax Division puts it this way: “Your application must be received by April 1st to be eligible for the current tax year's exemption.” The same calendar date every year. We read that sentence on 2026-08-04.
- Who do I file my Cobb County homestead exemption with?
- You file with Cobb County Tax Commissioner's Office, Property Tax Division, not with us and not with the state. Its own site is https://www.cobbtax.gov/property, and everything on this page was read from there or from a page it links.
- Which form does Cobb County want?
- The application Cobb County Tax Commissioner's Office, Property Tax Division publishes is at https://www.cobbtax.gov/Forms/Property%20Tax/Age%2065%204000%20Income%20Affidavit.pdf. We link it rather than hosting a copy, because a copy goes stale the day the county edits it and the county's own file does not.
- What happens if I miss the Cobb County deadline?
- Nothing we can source. No Cobb-official page found stating explicitly what happens to a late application (i.e., whether it rolls to next year); this is the general Georgia norm but was not stated verbatim on a Cobb page in the pages reached. That is not the same as “there is no remedy” — ask Cobb County Tax Commissioner's Office, Property Tax Division before assuming the year is lost.
- Who qualifies for the homestead exemption in Cobb County?
- In short: Applicants must own and occupy the property and provide proof of Georgia residency. Cobb's Tax Commissioner administers a Basic Homestead Exemption ($10,000 off county general and school value), a School Tax Exemption for age 62+, a Disability Exemption ($22,000, income-limited), a State Senior Age 65+ exemption ($4,000, income-limited), a State Veteran's Disability exemption for 100% VA-rated veterans, a State Surviving Spouse exemption for spouses/children of service members killed in action, and a Peace Officer/Firefighter Survivor exemption granting full homestead exemption to survivors of officers killed in the line of duty. City-specific exemptions must be filed separately with the relevant municipal tax office.
- Can I file online in Cobb County?
- Yes — Cobb County Tax Commissioner's Office, Property Tax Division publishes an online entry point at https://cobbcountygasf.tylerhost.net/smartfile/Filing/FilingType/Info/COBB_HOMESTEAD. Georgia counties open online homestead filing for the January–April season and close it the rest of the year. Outside that window this link may return an error or a “filing is closed” page — that is the county’s normal off-season behaviour, not a broken address. The paper form and the office below work all year.
- Do I have to re-apply every year in Cobb County?
- No. Once Cobb County Tax Commissioner's Office, Property Tax Division grants it, the exemption stays with the property while you own and occupy it. Moving house does end it, and the new home needs its own application.
Remind me before the next Cobb County deadline
Not open yet. Email reminders are the thing this site is being built to do, and the sending side is not finished. There is no form here on purpose: we would rather show you an empty space than take an address we cannot yet write to.
When it opens it will be one address and one county, a confirmation email you have to click before anything else is ever sent, and three reminders a year at most. No advertising, and nothing sold on.
