6 Ways to Pay a Williamson County Property Tax Bill

A Williamson County tax statement lands in the fall, and there is more than one way to pay a Williamson County property tax bill. Some paths are open to every owner. Others turn on age, on disability status, or on whether a taxing unit adopted the option at all.

6 things to know T. Kerr Property Group

Six ways to clear the bill, and who each one is open to.

01

What are all the ways to pay a Williamson County property tax bill?

The Williamson County Tax Assessor Collector takes the full amount through several channels. Online payment runs at tax.wilcotx.gov. An eCheck carries no fee. A credit or debit card carries one. Mailed payments go to 1848 Texas Trail in Georgetown. Drop boxes outside each office take checks and money orders. The office also takes payment in person and by telephone.

What a strong answer sounds like

A good plan names the channel and the date in one breath. Something like this: the eCheck cleared on January 20 and the receipt is saved. A mailed check is made payable to the Tax Assessor Collector by name, not to the county. A United States Postal Service postmark is honored on mail.

Red flag

A card payment made on the last day, with no receipt kept, is the weak version. The card route adds a fee that an eCheck does not carry. Writing the check out to the county, rather than to the Tax Assessor Collector by name, does not match what the office asks for.

02

My mortgage company pays the taxes, so is there anything left to do?

Texas Tax Code Section 31.02(a) makes the tax due on receipt of the bill. The tax is delinquent if it is not paid before February 1 of the next year. That date belongs to the owner, not to whoever sends the money. A statement in the mailbox is a prompt to check the account. It is not proof that someone else already handled it.

What a strong answer sounds like

A good check is a confirmed paid status on the owner's own account, with a date attached. Something like this: the account reads paid as of December 12. Asking the Williamson County Tax Assessor Collector beats reading a servicer statement and hoping.

Red flag

Assuming is the red flag. An escrow account set up on the wrong parcel, or on a number that has since moved, still reads as unpaid in February. The lien that attached to the property on January 1 stays there until the tax is paid. Confirming the status takes a few minutes.

03

Can half the bill be paid now and half later?

Texas Tax Code Section 31.03 lets a taxing unit that collects its own taxes offer a split payment. Half the taxes are paid before December 1. The rest is due before July 1 of the following year, with no penalty and no interest. The option is not statewide. It exists only where the governing body of that taxing unit has adopted it.

What a strong answer sounds like

A good answer names the unit and the deadline in the same sentence. Something like this: that unit adopted the split, so half is due before December 1. Owners should ask the collector about the unit that bills them, because one entity may offer it and another may not.

Red flag

Treating the split as automatic is the costly version. A missed second payment carries a 12 percent penalty on the unpaid amount under Section 33.01(b). Paying half, then letting July 1 pass, turns a timing choice into a penalty.

04

Who can pay a property tax bill in four quarterly installments?

Texas Tax Code Section 31.031 gives four equal installments with no penalty and no interest. It is open to an individual who is disabled. It is also open to one who is at least 65 and qualified for the Section 11.13(c) exemption. A disabled veteran, or the unmarried surviving spouse of one, may qualify under Section 11.132 or Section 11.22. The taxing unit must allow it.

What a strong answer sounds like

The first installment is paid before the delinquency date, with notice to the taxing unit. Where that date is February 1, the rest are due before April 1, June 1 and August 1. Williamson County runs this option for qualifying homeowners and publishes its own page on it.

Red flag

Starting the schedule without giving notice is the common miss. A missed installment carries a 6 percent penalty plus interest under Section 33.01(c), in place of the Section 33.01(a) penalty. An owner who qualifies and never asks pays the whole amount in one month instead of four.

05

What if the bill is already late and the full amount is not there?

Texas Tax Code Section 33.02 lets a collector enter an installment agreement on a delinquent tax. The collector must grant one on request for a residence homestead with a Section 11.13 exemption. The owner must have had no such agreement in the preceding 24 months. The agreement is written and paid monthly. It runs at least 12 months and no more than 36.

What a strong answer sounds like

While the agreement is current, the property cannot be seized or sold, and no suit may be filed. The Comptroller is plain that collectors are not required to offer this except on a residence homestead. A written request to the Williamson County Tax Assessor Collector is the place to start.

Red flag

Signing without reading is the risk here. Executing an installment agreement is an irrevocable admission of liability for all the taxes, penalties and interest it covers. The Section 33.01(a) penalty stops during the agreement on an 11.13 homestead. On default it accrues as if the agreement had never been made.

06

Should the bill be checked against the account before any of it is paid?

A per parcel breakdown of the taxing entities and their rates is published at williamsonpropertytaxes.org. That is where a Georgetown owner can see exactly which entities tax their own account. The Williamson Central Appraisal District appraises property and administers exemptions for Williamson County. A missing exemption is a question for that office.

What a strong answer sounds like

T. Kerr Property Group works with owners in Georgetown, Round Rock and Liberty Hill, and the breakdown at williamsonpropertytaxes.org is where the entity list on one account gets confirmed. WCAD publishes its own forms and deadlines and offers a property search. Its office sits at 625 FM 1460 in Georgetown.

Red flag

Paying first and asking later is the weak order. An exemption that is not on the account is not in the amount due. Confirming the exemptions with the appraisal district before the payment goes out is the only order that catches that kind of error.

Common Questions

Frequently asked questions.

When do Texas property tax bills get mailed?

Texas Tax Code Section 31.01(a) says the assessor shall mail tax bills by October 1, or as soon after that as practicable. The Comptroller adds that a taxing unit must give at least 21 days to pay after mailing the original bill. A statement that shows up later in the fall is normal.

What happens on February 1 if the bill is not paid?

Taxes are due on receipt of the bill and are delinquent if they are not paid before February 1 of the following year, under Section 31.02(a). A tax lien attached to the property back on January 1 under Section 32.01(a). It secures the taxes, penalties and interest imposed for the year. After the delinquency date the question shifts from how to pay to what the collector will agree to.

Does a postmark count if the payment is mailed on the last day?

The Williamson County Tax Assessor Collector honors a United States Postal Service postmark on mailed payments. The address is 1848 Texas Trail in Georgetown. The check is made payable to the Tax Assessor Collector by name rather than to the county. A drop box outside each office takes checks and money orders as well.

Is there a way to split the bill if nobody in the house is 65 or disabled?

Two paths exist, and neither one is automatic. Section 31.03 lets a taxing unit that collects its own taxes offer a split payment, but only where that unit has adopted it. Once a tax is delinquent, Section 33.02 lets a collector agree to monthly installments. The Comptroller notes that some collectors allow up to 36 months, and that none are required to offer it except on a residence homestead.

What if the tax bill arrives late?

Section 31.04(a) covers that. If a tax bill is mailed after January 10, the delinquency date is postponed to the first day of the next month that allows at least 21 days after mailing. A taxing unit must give at least 21 days to pay after the original bill goes out.
