County Tax Web Application
A web application that lets taxpayers look up tax records online and gives county staff one place to manage them.
Business goals
County tax offices answer the same questions all year, and the volume climbs as each deadline nears. Residents want to know what they owe, whether a payment posted and which parcel a bill covers. Staff need accurate records they can find while someone waits at the counter or on the phone. The client, a county government, needed a web application that handled tax information more efficiently for both residents and staff.
Project overview
Hexagon delivered a web application for a county government's tax work. Residents and property owners can look up a parcel, see what has been billed and check its status without visiting an office. County staff work from secured screens to find accounts, review records and answer questions. Because public access and staff access are separate, residents see what they should, and internal functions stay limited to authorized employees.
Challenges faced and solved
Tax records are public business, and they have to be right every time someone looks.
Deadline rushes at the counter
Phones and counters get crowded as a tax due date approaches. Most callers only want to confirm an amount or a status, and each question takes staff away from other work.
We put tax record lookup online, so residents can answer routine questions themselves at any hour, on or off deadline.
Finding the right account quickly
Taxpayers don't always have a parcel number to hand, and owners' names change or get recorded differently. A slow search keeps a waiting resident at the counter for longer.
We built search by parcel number, owner name and property address, so staff and residents can reach the same record different ways.
Separating public and staff access
A county must share tax information publicly while protecting internal functions. Mixing the two risks unauthorized changes to official records, which is a serious problem for any government office.
We kept the public lookup read-only and placed all editing behind a staff sign-in, with permissions set according to each employee's role.
Accounting for changes to records
Corrections and status changes happen, and a county has to explain them when a taxpayer or an auditor asks. Changes without a clear trail are hard to defend afterward.
We recorded changes to tax records by user and date, so staff can see what changed when a question comes up later.
Features
| Feature | Description |
|---|---|
| Residents and property owners | |
| 1. Parcel Search | Anyone can search by parcel number, owner name or address to find a tax record. |
| 2. Tax Record View | A record shows the property, tax year and billed amount, in language a homeowner can follow. |
| 3. Payment Status | Owners can see whether a bill is shown as paid or outstanding, which answers the most common phone question. |
| 4. Prior Year Records | Past tax years can be viewed, which helps when an owner needs them for a sale or for personal records. |
| 5. Printable Summary | Owners can print a record for their files or to give to a lender or title company. |
| 6. Due Date Information | Key dates appear alongside tax information, so owners don't have to phone the office to ask. |
| County tax staff | |
| 7. Account Lookup | Staff find accounts quickly while a resident waits, using the same search fields as the public plus internal details. |
| 8. Record Maintenance | Authorized staff can correct owner, address and account information through controlled screens. |
| 9. Status Updates | Staff record changes to an account's status, and the public view reflects them. |
| 10. Notes on Accounts | Staff keep internal notes on an account, so the next person handling it has the background. |
| 11. Delinquent Account Lists | Staff can pull a list of unpaid accounts when it is time to follow up. |
| Administrators and auditors | |
| 12. Role-Based Access | Each employee's permissions match their duties, which limits who can change official records. |
| 13. Change History | Edits are logged by user and date, which gives the office an answer when a change is questioned. |
| 14. Collection Reports | Managers can review billed and outstanding amounts by tax year. |
| 15. Data Exports | Staff can extract records for internal use and for other county offices that need them. |
How the platform is put together
Each layer has one job.
The result
Residents have a way to get routine tax answers online. County staff now handle accounts through one application with clear permissions.
| Area | Before | After |
|---|---|---|
| Checking a tax record | Call or visit the tax office | Search online by parcel, name or address |
| Payment questions | Answered by staff one at a time | Status visible on the public record |
| Updating records | Limited visibility into who changed what | Role-based editing with a change history |
| Reporting | Figures gathered by hand for each request | Reports and exports available from the application |
How we took it from idea to launch
Good software follows a process. Here are the six stages, and what happens in each one.
Discovery & Requirements
Goal: Define the product vision, target audience and core business requirements.
Key activities- Stakeholder interviews
- Market and competitor research
- Defining user personas
- Drafting technical specifications or a Product Requirements Document (PRD)
Design (UX / UI)
Goal: Create an intuitive user experience and visual interface.
Key activities- UX design: information architecture, user flows and wireframes
- UI design: high-fidelity mockups and interactive prototypes in Figma or similar tools
- Design system: colors, typography and component libraries
Development: Frontend & Backend
Goal: Build the functional application using agile sprints.
Key activities- Backend: set up databases, design APIs (REST, GraphQL), implement server logic, and configure authentication and authorization (OAuth, RBAC)
- Frontend: build responsive interfaces and connect components to backend APIs
- Version control: manage code through Git and GitHub
Security & Optimization
Goal: Harden the application against vulnerabilities and boost performance.
Key activities- Security: address the OWASP Top 10, including injection, XSS and CSRF, enforce encryption in transit and at rest, and implement rate limiting
- Optimization: code splitting and lazy loading, database indexing, API caching and load testing
- QA and testing: unit, integration and end-to-end tests
Beta Release
Goal: Deploy to a controlled group of real users to catch edge-case bugs and gather feedback.
Key activities- Set up staging and production CI/CD pipelines
- Launch a closed or open beta with real users
- Monitor errors through observability tools
Public Release (Launch)
Goal: Roll the software out to the general public.
Key activities- Final production deployment
- DNS configuration
- Marketing and onboarding rollout
- Post-launch performance and security monitoring
Business benefits
Residents can check common questions without staff help.
Staff reach the right account through several search paths.
Only authorized employees can change official information.
A change history shows staff what happened to an account.
Conclusion
A county tax office has little room for error and long lines at the worst times of year. Hexagon built the client a web application that gives the public a direct view of tax information and gives staff controlled tools for the records behind it. Residents get answers sooner, and the office has a clearer account of its own work. If your county or municipal office is still handling tax questions mostly by phone and counter visits, we would welcome a conversation.
