### Tempe Leaves Property Tax Rate Unchanged

The Tempe City Council voted four-to-three to leave property taxes unchanged at a rate of ```\$1.40 per \$100 of assessed value```.

The "assessed value" of each property class is determined using percentages set by the State Legislature. The residential assessment percentage is `10%`.

In Tempe the "primary" and "secondary" tax rates are `\$0.5183` and `\$0.8817`, respectively.

##### Exercises
1. The Tempe City Council voted `_____:_____` to leave the property tax rate unchanged.

2. `______%` of the Tempe City Council voted against lowering the property tax rate.

3. The median home price in Tempe increased by `_______%` between 2005 and 2006.

4. This year, Tempe's median home value was `\$194,000` versus `\$132,000` last year. The owner of a median assessed home will pay approximately `\$________ per month` more in property taxes.

##### Arizona Republic Math

The following was copied, without editing, from the 7 April 2007 Tempe section of the Arizona Republic.

```   "This year, the median full cash value of a Tempe based
on county assessments is \$194,000, up from \$132,000 last
year.  As a result, the average homeowner will pay about
almost \$63 more in city taxes this year.
```

Say what?

"Median" and "average" are two different statistics. The Republic's math doesn't match GDT's math.

##### Calculating Percent Increase in Property Tax

The following calculations were done using the Unix 'dc' (desk calculator) command. Note: 'dc' is a reverse polish notation calculator.

```   \$ dc
4k                   # four decimal digits of precision
194000               # 2006 median home value
.1*p                 # multiply by 10% to get assessed value
19400.0              # assessed value
100/p                # divide assessed value into number of \$100 units
194.0000             # taxable assessed value
1.4*p                # \$1.40 is Tempe's tax rate
271.6000             # city of Tempe taxes
132000               # 2005 median home value
.1*p                 # 2005 median home assessed value
13200.0              # 2005 median assessed value
100/p                # divide assessed value into number of \$100 units
132.0000             # taxable assessed value
1.4*p                # Tempe's tax rate
184.8000             # city of Tempe's taxes
-p                   # difference between 2006 and 2005 taxes
86.8
184.8/p              # divide by 2005 taxes (original amount)
.4696
100*p                # convert into a percentage
46.9600              # % increase in taxes
q                    # quit the calculator
```

The owner of a median priced home in Tempe will see a 46.96% increase in their property tax.

##### Update::2007.04.14

I (GDT) was wrong with respect to calculating Tempe residential property tax. A huge THANK YOU to Tempe mayor Hugh Hallman for sharing the following with me via an email message.

```   "However, the reason none of the 'math' works in the calculations
is that there are a couple of 'missing' facts.  First, the split
between 'primary' property tax and 'secondary' property tax in
Tempe is, essentially, \$.50 (primary) and \$.90 (secondary)."
```

The primary and secondary tax rates were specified at the start of this BAB, but I didn't include them in the email message I sent to the Tempe City Council. Mayor Hallman rounded the two tax rates for us. [The primary and secondary rates are 0.5183 and 0.8817, respectively.]

Mayor Hallman's email message continued with the following critical information.

```   "And Second, the reason that matters is there is a 'limitation'
imposed on the amount by which primary tax can increase.  Once
one applies the rather complicated formulae, the result is that
the primary tax, on mean average, can only increase by 14 percent
this first year, while the secondary will increase by the full
amount of the valuation increases (the full 47 percent on mean
average).  Accordingly, on mean average, the total property tax
bill at the median average house valuation, will increase in the
first year by 34 percent."
```
In a nutshell, increases in primary taxes are limited by law.

```      2005 city of Tempe tax on a \$132,000 residential property
=========================================================
secondary:  \$132,000 x .1 / 100 x 0.8817 = \$116.38
primary:  \$132,000 x .1 / 100 x 0.5183 = \$ 68.42
total:  \$116.38 + \$68.42 = \$184.80

2006 city of Tempe tax on a \$194,000 residential property
=========================================================
secondary:  \$194,000 x .1 / 100 x 0.8817 = \$171.05
primary:  \$194,000 x .1 / 100 x 0.5183 = \$100.55
adj. primary:  \$68.42 x 1.14 = \$78.00
total:  \$171.05 + \$78.00 = \$249.05

increase:  \$249.05 - \$184.40 = \$64.65
% increase:  \$64.65 / \$184.40 x 100 = 35.05%
```

Doh! GDT's calculation is a full one percent off from Mr. Hallman's and GDT doesn't know why. Recall, the Arizona Republic reported that the average tax bill will increase \$63. Using \$63 instead of \$64.65 results in a 34.16% increase in property tax, which better approximates the Mayor's 34%.

Onnie Shekerjian is an AzCentral.com blogger who also a Tempe City Council member. Onnie posted about Tempe's property tax increase saying the issue it was a done deal and that taxpayers had to look at other parts of their property tax statements. Onnie's posting prompted a comment from GDT (Gerald8100).

```   Comment from: Gerald8100; 04/14/07 @ 06:42
Onnie wrote: "TALK TO THE OTHER ENTITIES THAT COLLECT THE
OTHER 90% OF YOUR PROPERTY TAX."

No need to yell at us and I understand your posting was after
the debate, but those little 10 percents add up. For example,
the Maricopa Community Colleges have been nice little piggies
for the last decade. In 2006, 11.5% of my Maricopa County
property tax went to the community colleges.
