MPTSWeb, also known as the Megabyte Property Tax System from Megabyte Systems Inc., is a software platform used by many California counties to manage the complete lifecycle of property tax administration. It supports functions such as assessment, appraisal, tax collection, auditor operations like apportionments and AB8 distributions, appeals, and end-of-year processing. The system integrates data across assessor, auditor, and tax collector/treasurer offices to ensure ownership records, valuations, exemptions, and collections are aligned and accurate. MPTSWeb also provides public access through web modules, allowing taxpayers to view and print bills, check assessment data, and submit forms online.
In addition, it offers specialized tools for managing exempt property valuations, personal property such as boats, aircraft, and business assets, as well as address corrections, parcel splits, roll adjustments, and historical parcel mapping. In short, MPTSWeb is designed to streamline property tax operations for California counties while improving accuracy, transparency, and accessibility.
InvoiceCloud’s user-friendly electronic bill payment and presentment (EBPP) platform integrates into Megabyte’s Property Tax System (MPTS) and Megabyte’s Transient Occupancy Tax (TOT) System. Combined, both provide an improved payment experience for the taxpayer by reducing friction while offering an enhanced user experience for county staff with a simplified reconciliation and custom reporting. The result reduces manual efforts and creates county efficiencies.
