Reading the tables

Dates shown are statutory deadlines for the 2026 tax year. “Varies by Jurisdiction” indicates the deadline is set locally rather than at state level.

The Proptax Cycle

A process, repeatable.

Five phases. One continuous arc. From data preparation to year-end analysis, your portfolio is never between hands.

  1. 01

    Data Preparation

    We organize asset data, jurisdictional requirements, and reporting standards before the cycle begins.

  2. 02

    Compliance Processing

    We prepare and file returns across every relevant jurisdiction with precision and accuracy.

  3. 03

    Assessment Management

    We review all of the assessment notices received, identify discrepancies, and protect against over-assessment.

  4. 04

    Payment Processing

    We review and approve your tax bills, coordinate funding, cut checks, and reconcile every payment so nothing slips.

  5. 05

    Analysis & Planning

    We deliver frequent reporting, tailored to your needs, and identify opportunities to strengthen next year’s strategy.

Notice and appeal deadlines vary by jurisdiction and should always be verified by a tax professional. This calendar should be used as a guideline only.
