The Amarillo ISD Board of Trustees had a choice Monday: adopt the minimum debt service tax rate required under a new state law or go slightly higher in an effort to save taxpayers money on debt over the long term.

Trustees unanimously chose the second option.

The board approved a total property tax rate of $0.8644 per $100 of taxable value, including an interest and sinking rate of $0.159. That I&S rate is half a cent higher than the district’s newly calculated minimum of $0.154.

On its face, approving a tax rate higher than the minimum might seem like an unusual way to save taxpayers money. But district officials argue that collecting slightly more for debt service now allows Amarillo ISD to pay down bond debt earlier and avoid interest costs in future years.

“It is a difference of half a cent,” Chief Financial Officer Daniel West told trustees.

The decision comes as school districts adjust to Senate Bill 1453, which requires districts to calculate a minimum debt service tax rate. That rate represents the minimum property tax revenue necessary to cover mandatory debt obligations for the year.

AISD was not required to stop at that minimum. Districts can adopt a higher rate with approval from a majority of their school boards.

West recommended doing exactly that, pointing to AISD’s history of using excess I&S collections to retire outstanding bond debt ahead of schedule. He said the district has followed that practice since 2018.

“The district has a long history of maintaining a steady rate and using fund balance and debt service to pay debt early,” West said. “That is what I would like for the board to continue doing.”

There is a reasonable financial argument behind that approach. Paying principal earlier can reduce the amount of interest taxpayers ultimately have to cover. According to West, AISD has reduced future principal and interest payments by $39.3 million since 1999 through its management of the debt service fund and has also undertaken multiple refundings as debt has been retired early.

Still, taxpayers are likely to be more interested in what happens to their own bills.

AISD’s overall tax rate is actually declining, from $0.8712 last year to $0.8644 this year. The district's maintenance and operations rate is $0.7054, a decrease Parish attributed to state-mandated tax compression.

But a lower tax rate does not necessarily mean a lower tax bill.

According to the district's public notice, the average taxable value of a residence in AISD is around $100,000 this appraisal year. The average homeowner is expected to pay about $25 more in AISD property taxes than last year.

That distinction matters. Tax rates tend to receive much of the attention during budget season, but taxpayers ultimately pay based on both the rate and the taxable value of their property.

It is also important to distinguish between the two sides of the district's tax rate. Maintenance and operations revenue helps fund the everyday operation of the school district, with West saying 83% of the M&O budget goes toward payroll. The debt service fund is much more restricted. Its property tax revenue can only be used for principal, interest and fees associated with debt.

AISD expects to pay approximately $15.1 million in minimum debt service during the upcoming fiscal year.

The question for taxpayers, then, is not simply whether AISD adopted a rate above the state-calculated minimum. It is whether paying an additional half-cent toward debt today produces enough savings in future interest costs to justify the additional collection.

AISD's past results provide some support for the strategy, but the district should continue showing taxpayers exactly how much early debt payments save and how those savings compare with the additional taxes collected.

Transparency is particularly important when a governing body voluntarily chooses a rate above the minimum allowed under state calculations.

Trustees made that choice unanimously Monday, voting 7-0 both to exceed the minimum rate and to adopt the overall $0.8644 tax rate.

For homeowners, the immediate result is relatively straightforward: AISD's tax rate is lower than last year's, but the average homeowner is still expected to pay a little more. The district's case is that putting some of that money toward debt faster today will leave taxpayers with less interest to pay tomorrow.

Whether that strategy continues to deliver meaningful savings is something worth watching each budget year.
