Bond Ratings: How They Affect Borrowing Costs (and Indirectly, Your Tax Rate)
If you’ve looked at your taxing unit’s annual financial reports or bond-related communications, you may have seen a reference to a credit rating — something like ‘AAA’ or ‘AA+’ from agencies like Moody’s, S&P, or Fitch. Here’s what these ratings mean and how they connect, indirectly, to your property tax rate.

What a Bond Rating Is
A bond credit rating is an assessment, by an independent rating agency, of how likely a bond issuer is to repay its debt as promised. Ratings range from the highest categories (like ‘AAA’ or ‘Aaa’) down through various levels indicating progressively higher perceived risk.
What Goes Into a Rating
Rating agencies generally consider factors like:
- The taxing unit’s overall financial health and reserves
- The strength and diversity of its tax base/economy
- Its existing debt levels and debt management practices
- Its track record of budgeting and financial reporting
Why Ratings Matter for Borrowing Costs
When a taxing unit issues bonds, investors who purchase those bonds are essentially lending money and expect to be compensated for risk. A higher credit rating generally signals lower risk to investors — which can translate into the taxing unit being able to borrow at a lower interest rate than an entity with a lower rating would pay for similar debt.
How This Connects to Your Tax Rate
As discussed in our article on debt service, the I&S portion of a tax rate covers repayment of bond debt — including interest. All else equal, a lower interest rate on bonds means lower total repayment costs, which means a lower I&S rate is needed to cover that debt service compared to the same amount of debt at a higher interest rate.
A Long-Term, Indirect Effect
This isn’t something that changes your tax bill from one year to the next in an obvious way — it’s more of a long-term structural factor. A taxing unit that maintains strong financial management (and thus a strong credit rating) over time may, all else equal, have somewhat lower borrowing costs on the bonds it issues, compared to a taxing unit with weaker finances and a lower rating issuing similar debt.
Where You Might See This Mentioned
Credit ratings often come up in:
- A taxing unit’s annual financial reports or bond offering documents
- News coverage of a bond election or upcoming bond issuance
- Discussions of refunding bonds, where a rating change might be mentioned as a factor
This Is Background Information, Not a Call to Action
Understanding bond ratings doesn’t change anything about your individual tax situation directly — it’s background information that can help you understand financial discussions about your local taxing units, if you encounter them.

Lower interest costs on bonds mean a lower I&S rate is needed to cover the same debt service, all else equal.
No — this is more of a long-term structural factor affecting future borrowing costs, not an immediate change to your bill.
