Compliance Analysis
Key implementation requirements and action items for compliance with this legislation
Implementation Timeline
Effective Date: September 1, 2025
Compliance Deadline:September 1, 2025 (Internal accounting and legal tracking systems must be active to capture interest accruals immediately).
Agency Rulemaking: No formal rulemaking is mandated for the Comptroller; however, individual County Tax Assessor-Collectors will implement internal processing protocols. Expect inconsistency between counties regarding the "trigger date" for the 60-day payment window during Q4 2025.
Immediate Action Plan
1.Audit Pending Protests: Review all open tax protests. If resolution is close, strategize whether to finalize before or after Sept 1, 2025, to leverage the new interest protections.
2.Update Accounting Software: Configure alerts for "Day 61" post-resolution to auto-generate demand letters for unpaid refunds + interest.
3.Revise Lease Templates: Modify NNN operating expense clauses to address the allocation of penalty interest.
4.Calendar the Statute: Hard-code the 60-day litigation deadline into your legal case management software; missing this window is now a complete waiver of rights.
Operational Changes Required
Contracts
Triple-Net (NNN) Leases: You must amend standard lease templates. Define "Tax Refunds" to clarify ownership of the statutory 12% interest penalty. Specify whether this interest is credited to the tenant (who paid the tax) or retained by the landlord (as compensation for administrative oversight).
Tax Consultant Engagement Letters: Review fee structures. If your consultant takes a percentage of "tax savings," clarify if this includes the 12% penalty interest paid by the county for late refunds.
Hiring/Training
Accounts Receivable/Tax Teams: Train staff to stop filing refund applications for amounts over $20, as these are now automatic. Conversely, implement a manual workflow to apply for refunds *under* $20 within 3 years, or these funds will be forfeited.
Legal Counsel: Attorneys must be briefed on the new hard deadline: lawsuits to compel refunds must be filed within 60 days of a denial or receipt of an overpayment notice.
Reporting & Record-Keeping
Interest Tracking: Implement a ledger to track the "Date Liability Arises" (e.g., date of appeal determination). If the refund check arrives after Day 60, your system must automatically flag the transaction to demand the mandatory 12% interest.
Notice Retention: Retain all "Notices of Overpayment" from Tax Collectors. These notices are now the evidentiary trigger for the statute of limitations on lawsuits.
Fees & Costs
Revenue Opportunity: The law creates a new revenue stream via the 12% annual interest penalty on late government payments.
Litigation Costs: Attorney’s fees in suits to compel refunds are capped at the greater of $1,500 or 30% of the refund amount.
Strategic Ambiguities & Considerations
"Date Collector Learns": The 60-day clock starts when the collector "learns" of the refund liability. This is subjective. Counties may argue they did not "learn" of a determination until administrative processing was complete, artificially delaying the interest clock.
*Mitigation:* Send certified copies of appeal determinations to the Collector immediately to establish a definitive "knowledge date."
W-9 Requirements: The law restricts courts from demanding IRS forms (like W-9s) before ordering refunds, but County Auditors often require them for anti-fraud compliance. Expect friction and payment delays where counties refuse to issue checks without vendor setup.

Presently, the tax accessor-collector is not required to send a refund to a taxpayer unless that taxpayer requests a refund. If the taxpayer does not request a refund the amount due back to the taxpayer would then be applied towards their next year's property tax. Taxpayers should not have increased barriers to the funds to which they are entitled, and they deserve to have any overpayment returned to them with the fewest bureaucratic hurdles possible.
As proposed, S.B. 850 amends current law relating to the payment of certain ad valorem tax refunds.

This bill does not expressly grant any additional rulemaking authority to a state officer, institution, or agency.

Provides that the presiding officer of the governing body of the taxing unit is not required to sign the application for the refund or any document accompanying the application to indicate the governing body's approval or disapproval of the extension of the deadline prescribed by Subsection (c) as it relates to the application, rather than of the refund.
