 Notice of 2017 Tax Year Proposed Property Tax Rate for City of Katy

City property taxes become due on October 1 and taxpayers have until January 31 of the following year to pay their tax bill before taxes become delinquent.  It is each taxpayer’s responsibility to seek out all taxes due, as failure to send or receive a tax bill does not affect the validity of the tax, penalty, interest, due date, existence of a tax lien or any procedure instituted to collect a tax.

Appraisal is based on market value as of January of the tax year. If you have any questions regarding your property value, contact the appraisal district for the county where the property is located.  Property appraisals in the City are provided by the Waller County Appraisal District (979-921-0060), the Fort Bend County Appraisal District (281-344-8623) and the Harris County Appraisal District (713-957-7800).

Tax Rates

The City tax rate is usually set during September of the tax year.  The City of Katy tax rates for the past 10 years are:

  2008      2009       2010        2011        2012       2013      2014       2015       2016     2017
 .59372    .59372    .59372      .59372     .58672    .56672   .54672    .52672     .50672   .48672

The current tax rate for 2017 is $0.486720/100

Tax Liability Calculation

To determine your tax liability, divide the value of your home by 100, then multiply by the current tax rate.  For example, a home valued at $100,000 would pay 2017 city taxes in the amount of $486.72.

$100,000 ÷ 100 x .486720 = $486.72

Exemption Eligibility

Tax exemptions exclude all or part of a property’s value from taxation.  The City offers numerous exemptions.  You must apply for all exemptions through the Central Appraisal District of the county in which you live.

Residence Homestead

If the property is your principal residence, you may qualify for a homestead exemption.  The City offers a 20% exemption (minimum $5000).


If you qualify for a residential homestead exemption, you may also qualify for an additional exemption of $10,000 in 2017 and $100,000 for 2017 if you are disabled.

Disabled Veteran

Exemptions from $5,000 to $12,000 for veterans, with exemptions from $2,500 to $5,000 for a spouse and children of a member of the armed services who dies while on active duty.  100% exemption is allowed for a veteran who is 100% disabled.

Over 65

If you qualify for a residence homestead exemption, you may also qualify for an additional exemption of $100,000 in 2017 and $100,000 for 2017.  You may not receive both a disability and over 65 exemption.

Payment Schedule

Taxes are due October 1 of each tax year and are considered delinquent if payment is not postmarked on or before January 31.  If January 31 falls on a Saturday or Sunday, taxes are considered delinquent if not postmarked on or before the following Monday.  Penalty and interest accrue at the following rate if taxes remain unpaid by the delinquent date:

February      March         April            May          June         July
7%             9%           11%           13%         15%        18% (plus 20% for collection costs)
* For August and thereafter, add 1 percent per month.
Payment Options/Deferrals for Senior Citizens

If residents claiming the over 65 homestead exemption pay at least one-fourth of the taxes due before the delinquency date, the balance may be paid in three equal installments without penalty or interest.  The first installment must be paid before April 1, the second installment before June 1 and the third installment before September 1.

If you are a homeowner age 65 or older, you may defer or postpone paying any delinquent property taxes on your home for as long as you own and live in it.  To postpone your tax payments, file a “tax deferral affidavit” with your appraisal district.  A tax deferral only postpones paying your taxes.  It does not cancel them.  Interest is added at the rate of 8 percent per year.

Once you no longer own your home or live in it, past taxes and interest become due.  Any penalty and interest that was due on the tax bill for the home before the tax deferral will remain on the property and also become due when the tax deferral ends.
