Property Tax Appeals in Georgia
Homeowners in Cobb County, GA, have the opportunity to appeal their property tax assessments if they believe there has been an error or if the assessed value does not accurately reflect the property's market value. The appeal process begins with the homeowner filing a notice of appeal with the Cobb County Board of Tax Assessors. This must be done within 45 days of receiving the assessment notice. Once the appeal is filed, the board reviews the case and may make an initial decision. If the homeowner disagrees with this decision, they can further appeal to the Board of Equalization, which is responsible for hearing and deciding property tax disputes.
The appeal process involves several steps, including gathering evidence to support the claim, such as comparable sales data, property condition reports, or independent appraisals. Homeowners may also need to attend a hearing where they can present their case. The potential outcomes of an appeal include a reduction, confirmation, or increase in the assessed value, which will directly impact the property tax bill.
Ownwell assists homeowners throughout this process by offering expert guidance and support. Our team helps gather necessary documentation, provides strategic advice, and represents homeowners during hearings. By leveraging our expertise, homeowners can navigate the complexities of the appeal process more efficiently and increase their chances of a favorable outcome. With Ownwell's assistance, homeowners can ensure that their property taxes are fair and reflective of the true market value of their property, potentially saving them significant amounts of money.
Exemptions in Georgia
Cobb County offers several property tax exemption programs designed to ease the financial burden on homeowners. The most common exemption is the Homestead Exemption, which is available to homeowners who occupy their property as their primary residence. This exemption reduces the assessed value of the home, thereby lowering the property tax bill. Senior citizens aged 62 and older may qualify for additional exemptions, such as the Senior School Tax Exemption, which excludes school taxes from their bill, significantly reducing the overall tax obligation.
Disabled veterans and their surviving spouses may be eligible for the Disabled Veteran Exemption, which offers substantial tax relief based on specific criteria related to service-related disabilities. Additionally, the Floating Inflation-Proof Exemption protects homeowners from increased assessments due to inflation, ensuring that taxes remain stable even if property values rise.
To apply for these exemptions, homeowners must submit the appropriate application forms to the Cobb County Tax Assessor's Office, along with any required documentation proving eligibility. Deadlines and specific requirements may vary, so it's crucial to verify details well in advance.
Ownwell assists homeowners in navigating these exemption programs, ensuring that they maximize their savings.
