Gwinnett County Property Search, Assessor Map, Values & 2026 Tax Records
Searchers often use the phrase Gwinnett County property appraiser, but Georgia’s official terminology is different. Property valuation, assessment records, ownership data and assessment appeals are handled by the Gwinnett County Board of Assessors.
The Assessor’s online property system can be searched by parcel number, owner name or property address. For an actual 2026 tax bill or payment, use Tax Commissioner Denise R. Mitchell’s office. For deeds, plats and liens, use the Gwinnett County Clerk of Superior Court.

How to Search Gwinnett County Property by Owner, Address or Parcel
Gwinnett County’s official Assessor page sends property-search users to its Schneider qPublic system. The county specifically recommends using a parcel number, property owner name or property address when researching a parcel or nearby sales.

Gwinnett Fair Market Value, Assessed Value and Taxable Value
Georgia property is generally assessed at 40% of fair market value. Gwinnett then applies applicable exemptions before the appropriate millage rates are used to calculate taxes.
Fair Market Value
The Assessor’s estimate of the property’s January 1 market value under Georgia appraisal requirements.
Assessed Value
Normally 40% of fair market value for ordinary taxable real estate in Georgia.
Taxable Value
The assessed value remaining after applicable exemptions are deducted for a taxing authority.
Simple calculation example
Gwinnett Mailed About 311,000 Real Property Assessment Notices on May 15, 2026
The Board of Assessors mailed approximately 311,000 residential and commercial Annual Notices of Assessment on May 15, 2026. The notice reports the property’s January 1 value and applicable assessment information; it is not the tax bill.
The 2026 appeal period is now closed for the general residential and commercial notices mailed May 15. The deadline shown on the notice controls when a property has a different notice date.
View Assessment Notice InformationWhat to check on the 2026 notice
- Confirm the parcel and mailing information.
- Review the appraised value as of January 1, 2026.
- Check exemptions or credits shown on the notice.
- Locate the appeal deadline printed on the notice.
- Compare questionable values with the Assessor’s property and sales records.
2026 Gwinnett Homestead Rules Changed the Filing Timing
Gwinnett’s current Tax Commissioner guidance says homestead applications are accepted year-round. To reduce taxes for the current year, the application must be received by the appeal deadline shown on the Annual Notice of Assessment.
That is a key 2026 change from older Gwinnett guidance that used an April 1 current-year deadline. For typical residential notices dated May 15, 2026, the appeal deadline shown was June 29, 2026.
S1R Regular Homestead
No age or income limit. The owner must own and occupy the home as a primary residence as of January 1.
Current published amounts include $10,000 off assessed value for County purposes, $8,000 for school and $7,000 for recreation.
Value Offset Exemption
Gwinnett’s Value Offset Exemption is automatically applied when a homestead exemption is granted.
It holds taxable value constant for the County Government portion when market value rises. It does not freeze school or city taxes and applies to the home and up to five acres.
Before applying
- Own and occupy the home as your primary residence as of January 1
- Use only one homestead exemption between spouses
- Update the Gwinnett address on driver’s license and vehicle registrations
- Use the same application to be considered for applicable Gwinnett exemptions
- Allow about 6–8 weeks for current applications to be reviewed
After opening the homestead page
- Confirm you owned and occupied the home on January 1.
- Review the regular, senior, disability or other exemption requirements.
- Update address records before applying if needed.
- Submit the single homestead application online, by mail or in person.
- Watch for requests for supporting documents and allow the stated review period.
2026 senior school exemption
Gwinnett’s current L5A Senior School Exemption requires the qualifying owner to be at least 65 as of January 1 and meet the annual income test. For 2026, the Tax Commissioner lists a maximum applicable income figure of $124,648, using the specified 2025 Georgia income-tax return figure.
Compare Gwinnett ExemptionsHow Gwinnett Property Appeals Work After You File
Georgia gives property owners 45 days from the Annual Notice of Assessment date to appeal value, taxability, uniformity or an exemption issue. For the main 2026 real-property notice cycle, Gwinnett states that the final filing date was June 29, 2026.

A PT-311A or qualifying written appeal may be mailed. A mailed appeal must be postmarked by the deadline.

Appeals may be hand-delivered to the Assessors’ Office at 75 Langley Drive in Lawrenceville.
What happens after filing?
The appraisal staff reviews the appeal
Gwinnett may agree with your asserted value, propose another value or leave the assessment unchanged.
An amended notice may be issued
If the Assessor changes the value, you may receive a PY-306C Amended Notice of Assessment.
You have 30 days to reject an amended value
If you disagree with the amended value, respond within the 30-day period stated by the County to continue the appeal.
Check appeal status after a few days
Gwinnett advises allowing at least three days after filing before using its online appeal-status search.
Gwinnett’s 2026 Property Tax Bills Are Due November 15
The Tax Commissioner reports that the 2026 property-tax bills have been mailed and are due November 15, 2026. This is the controlling bill stage of the property-tax cycle, after assessment values and millage rates have been established.
Late Charges
The Tax Commissioner currently lists 0.81% interest per month on unpaid balances.
A 5% penalty is added after 120 days and can repeat every 120 days, up to a 20% maximum penalty.
Before paying the 2026 tax bill
- Search the correct parcel or property-tax account.
- Verify the owner, parcel and 2026 tax year.
- Confirm any homestead exemption or tax credit shown.
- Review whether a separate city bill may also apply.
- Save the official payment confirmation after paying.
One bill or two? Your city matters
For 2026, the Tax Commissioner’s bill guide states that properties inside Berkeley Lake, Grayson and Peachtree Corners receive city and county taxes on one combined bill.
Residents inside Gwinnett’s other cities generally receive a separate city tax bill from that municipality. This is why two properties with similar appraised values can have different billing arrangements.
Use the Superior Court Clerk for Recorded Gwinnett Real Estate Documents
The Gwinnett Clerk of Superior Court records and indexes real-estate documents including deeds, plats, condominium floor plans and lien filings. The Clerk reports that its available land records date to September 26, 1871, after earlier records were lost in a fire.

Why Property Location Inside Gwinnett Changes the Tax Research
Unincorporated Gwinnett
The bill can include County service-district components for police, Fire/EMS, recreation and other services in addition to schools and countywide levies.
Lawrenceville, Duluth, Suwanee & Other Cities
Many municipalities bill their own city taxes separately. Do not assume the County Tax Commissioner bill is the only bill associated with a city property.
Community Improvement Districts
Properties in certain commercial CIDs can have additional millage. A business property in a CID should be matched to its exact tax district before estimating taxes.

Gwinnett mailed the main residential and commercial notices on May 15, 2026, and the County states that the final 2026 appeal date for that cycle was June 29, 2026. A separately dated notice should be checked for its own printed deadline.

Current 2026 Gwinnett guidance says applications are accepted year-round and must be received by the appeal deadline printed on the assessment notice to reduce current-year taxes. Older Gwinnett materials that state April 1 reflect the earlier filing rule.
7. What is Gwinnett’s Value Offset Exemption?

10. Where should I search for a Gwinnett County deed, plat or lien?
Use the Gwinnett County Clerk of Superior Court’s Deeds and Land Records resources. The Clerk records deeds, plats, condominium floor plans and lien filings; the Assessor’s ownership field is not a substitute for recorded legal documents.
