Tax Lien Warning

⛔ Texas Attorney Fee Warning: After July 1, delinquent property taxes are referred to a collection attorney. An additional 15–20% attorney fee is added on top of your penalty and interest. On a $5,000 tax bill, this adds $750–$1,000 instantly. Pay before July 1 to avoid this.

How to read the Montgomery County Tax Office result

Important fields on an account page
Field What it tells you What to do with it
Account Number Tax Office account identifier. Save it for payments, receipts and phone calls.
CAD Reference Link to the appraisal-side property record. Use it to reconcile the Tax Office account with MCAD.
Current / Prior / Total Due Balances by current and older tax years. For delinquent accounts, use the live payoff rather than an old statement.
Last Payment Last recorded current-year payment amount, payer and date. Useful for escrow and duplicate-payment checks.
Active Lawsuits Whether the account page shows an active tax suit reference. Call before relying on a routine online payoff when litigation is shown.
Pending Payment Pending credit-card/eCheck status. Do not submit another payment while a transaction is still pending.
Values / Exemptions Tax portal copy of appraisal information. Use MCAD for changes, protests or exemption questions.
Future-date estimate A tool to estimate amount due on another date. Useful for delinquent planning; confirm the actual payoff before sending money.
Database warning: The Tax Office portal states that it does not guarantee the accuracy or reliability of website data. When the online display conflicts with a tax statement, legal notice or account-specific instruction, contact the Tax Office before acting.
Current payment costs

Montgomery County online tax-payment fees and confirmation checks

The Tax Office now publishes the processor fees directly. For a large property-tax bill, checking the payment method before checkout can save a meaningful amount.

Current online payment fees published by the Tax Office
Method Published fee Best use Before submitting
eCheck $0.00 Lowest-cost listed online route. Confirm routing/account details and available funds.
Debit card 1.00% of amount; $1 minimum Card convenience when debit is preferred. Compare the fee against eCheck before approving.
Credit card 2.05% of amount; $1 minimum Credit-card convenience. Percentage fee can be substantial on a large bill.
A confirmation number is not final proof that funds cleared. The Tax Office says the confirmation confirms an attempt to pay. Check your financial institution and later verify the tax account. Returned items may incur a fee.
Fee rule: The Tax Office says Certified Payments convenience fees are non-refundable. The live checkout screen controls if the vendor changes a fee later.
Troubleshooting

No Montgomery County tax account found? Try this order

Owner search fails Use last name first, shorten the name and remove middle names or punctuation.
Address search fails Try street number plus the main street name because the field is a “Starts With” search.
Recent purchase Search both the current and previous owner, then compare the MCAD property record and deed history.
Many parcels Use the Portfolio feature and reconcile each account/CAD reference separately.
Zero balance but another bill arrived Check whether the bill is from a MUD, utility district or separate collector.
Value or exemption is wrong Stop searching the Tax Office for a fix; use MCAD.
Useful Tax Office call script “I am checking property-tax account [number] / CAD reference [number] for [property address]. I need to confirm [the current balance / whether a payment posted / which years or jurisdictions your office collects].”
Escrow, closing & partial payment

Mortgage escrow, missing statements and partial-payment problems

These problems often look like Tax Office errors but require different next steps. The county FAQ gives specific instructions for mortgage-paid accounts, new buyers and taxpayers who cannot pay the full bill at once.

Your mortgage company is supposed to pay

Do not pay twice just because a statement arrived First check the lender or escrow account and the live Tax Office account for a pending or posted payment.
If the lender needs the paper notice The Tax Office instructs taxpayers who receive a statement that should be escrow-paid to write the loan number on the notice and send it to the mortgage company.
If you want to pay your own taxes The county FAQ provides a Taxpayer Delete Mortgage Code form route. Confirm the change with the Tax Office rather than assuming the lender request has stopped.

You bought the home and the old owner is still shown

Name or mailing record is wrong

MCAD controls general ownership/name/address corrections on the appraisal record. A Tax Office payment does not update title or appraisal ownership.

Taxes were prorated at closing

A seller credit at closing does not necessarily mean the tax bill was paid to the Tax Office. Check the closing disclosure and ask the title company who was responsible for the actual tax payment.

You cannot pay the full amount

The Tax Office accepts partial payments. It says partial amounts are applied pro-rata to tax, penalty, interest and collection penalty when applicable. A balance left after the timely deadline can continue to accrue penalty and interest.

For a mailed partial payment, write the property account number on the check or money order
Add the words “partial payment” when following the county FAQ instruction
After posting, recheck the remaining balance rather than subtracting it yourself
For a delinquent account, request the amount due through the date you plan to pay
No statement by November 1? The county says to contact the Tax Office and request one. Failure to receive a tax notice does not cancel the tax, penalty, interest, due date, lien or collection procedure.
Montgomery-specific risk

A zero County Tax Office balance may not cover every MUD or special district

Montgomery County has many MUDs, utility districts, ESDs, cities, school districts and other taxing units. The county portal searches accounts collected by the Montgomery County Tax Office; some local units can use another collector.

Open the MCAD property record Write down every taxing unit attached to the parcel for the selected year.
Open the County Tax Office statement List the jurisdictions included in the county-collected bill.
Compare the two lists Look for a MUD, utility district, PID or other entity that does not appear on the county statement.
Check a separate collector when needed Use the collector printed on that district’s own statement or the district’s official contact route.
Repeat for prior years A clean current year does not prove every older account is clear.
Keep all receipts For a purchase, refinance or escrow audit, save county and separately collected district receipts together.
Buyer/escrow tip: Ask the title company or lender to identify every collector tied to the property—not only the Montgomery County Tax Office account.
Tax records explained

Which Montgomery County tax record do you actually need?

Tax Office vs MCAD vs County Clerk
Need Correct source Why
Current balance / receipt Tax Office Collector records payments and balances.
Appraised value MCAD Appraisal district determines value.
Homestead exemption MCAD Exemption applications and appraisal-roll changes are handled there.
Taxing units MCAD + collector statements Use both to detect separate MUD/special-district collectors.
Deed / lien / release County Clerk These are recorded real-property documents, not tax-appraisal records.
Protest status MCAD / ARB The Tax Office cannot lower an appraised value.
Tax foreclosure status Tax Office + court/constable records Delinquent collection and sale status can be time-sensitive.

Official payment-plan PDF

Which current-account payment plan fits your situation?

The county payment-plan PDF is explicitly for current accounts only. Use the account status first; a delinquent or litigated account may need a different arrangement.

Montgomery County Tax Office current-account plans
Plan Who can use it Published schedule Key condition
One-time All taxpayers, business owners and business personal-property accounts One payment by January 31 Penalty and interest begin February 1 if unpaid and no other applicable rule postpones delinquency.
Quarter payment Qualified residential owners with a Homestead exemption plus age 65+, Disabled Person or Disabled Veteran exemption Jan. 31, Mar. 31, May 31, July 31 At least one-fourth of the total bill must be paid by Jan. 31 to enroll for that tax year.
Pre-payment Taxpayers and business owners without mortgage escrow; current accounts Monthly installments through Sept. 15; number varies by start date Taxes must be current; an October statement shows any remaining balance.
Mortgage escrow pays the bill The pre-payment plan is not the county’s route for an escrowed account. Reconcile with the lender first.
Homestead only, no qualifying additional exemption Do not assume the four-quarter plan applies. The PDF requires the listed additional age/disability/veteran exemption.
Already delinquent The PDF is for current accounts. Call for a delinquent payoff or arrangement instead of back-dating the quarter plan.
Current account and want smaller monthly amounts Ask about pre-payment early enough to finish scheduled prepayments by Sept. 15.
Due date & delinquency

October statement, January 31 postmark and penalty timeline

The county FAQ says tax notices are usually mailed in October and taxes are due when the statement is received. January 31 is normally the final date to avoid delinquency; mailed payments are posted according to the postmark.

October — statements usually mailed Mortgage companies request their clients’ statements from the Tax Office; some property owners may still receive a copy directly.
November 1 — missing-statement check If no statement has arrived, the county FAQ says to contact the Tax Office and request one rather than waiting for a delinquency notice.
January 31 — normal timely-payment cutoff If mailing in late January, make sure the envelope receives a USPS postmark no later than January 31. Do not assume dropping mail in a box guarantees that day’s postmark.
February 1 — normal delinquency begins The county says penalty and interest start to accrue unless an applicable payment plan or other legal rule changes the date.

How the county describes penalty and interest

General statutory schedule described in the Montgomery County FAQ
Point in delinquency Penalty Interest What to do
First delinquency month 6% 1% Use the live account rather than a generic calculator.
Each following month before July Penalty increases 1 percentage point per month Adds 1% per month Ask for a payoff through the planned payment date.
July 1 Final 2% increase brings statutory penalty to 12% Continues at 1% per month Check for collection/legal charges or active lawsuits on the account.
Do not use a statewide “daily penalty” calculator. The county describes penalty and interest on a monthly statutory schedule, and an account can also have payment-plan, postponed-delinquency, collection or litigation factors. The live account/payoff is the safer figure.
Late-account call script “Please give me the total payoff for account [number] through [date]. Confirm every unpaid year, penalty, interest, collection charge, active lawsuit and any pending eCheck/card payment.”
Official Form 50-114 PDF

Residence homestead exemption: prepare the MCAD application correctly

The Montgomery County Tax Office does not decide exemption eligibility. File the current Form 50-114 and supporting documents with MCAD. The form itself says not to file it with the Texas Comptroller.

What Form 50-114 asks you to identify

Which residence-homestead exemption(s) you are requesting
Whether you live in the property and when you began occupying it as your principal residence
Owner/applicant names and ownership percentages
Physical property address and legal description, if known
Whether the applicant is identified on a deed/recorded instrument
Whether the property is heir property, manufactured housing or partly income-producing

Identification and supporting-document check

Most applicants

The form instructs owners to attach a copy of each property owner’s Texas driver license or state-issued personal ID. The ID address generally must correspond to the residence-homestead address, subject to listed exceptions/waivers.

Special ownership situations

Heir-property and manufactured-home applicants may need additional ownership evidence, affidavits, death certificate/utility documentation or manufactured-home ownership records described on the form.

Filing and late-application windows shown on the current form

Form 50-114 timing guide
Situation Form guidance Practical step
General filing Generally Jan. 1 through Apr. 30; completed application is generally due no later than Apr. 30. File with MCAD and retain proof of submission.
Late residence homestead, including age 65+ or disabled May be filed up to two years after the ordinary deadline under the form’s cited rule. Ask MCAD which tax year(s) are still eligible.
Certain disabled-veteran late applications The current form describes up to five years after the delinquency date for specified disabled-veteran claims; surviving-spouse rules differ. Use the exact exemption category and MCAD guidance rather than assuming the longer window applies.
Already granted The form says annual reapplication is generally not required unless the chief appraiser asks, except when seeking another property/exemption. Still review the appraisal record and tax statement for the exemption.
Privacy warning: Form 50-114 can request sensitive identification information. Submit it only through MCAD’s official filing route. Do not send driver’s-license, Social Security, bank or card information to TaxCollectors.org.
Posting delay: The Tax Office says MCAD exemption changes may take about 4–6 weeks to appear on the Tax Office website. Keep the MCAD approval and keep monitoring the payment deadline while the update moves between systems.
Deferral is not forgiveness

Over-65, disability and veteran residence-homestead tax deferral

The Tax Office says qualifying Texans age 65 or older, disabled persons and disabled veterans may be able to postpone current and/or delinquent taxes on an owned and occupied residence homestead by filing a deferral affidavit with MCAD.

What the deferral does
  • Postpones payment; it does not erase the tax.
  • The county says deferred taxes accumulate 5% interest per year (0.4167% per month).
  • Already-due penalties, interest or attorney fees are not cancelled by filing the deferral.
When the deferred amount can come due
  • When the homeowner or qualifying surviving spouse no longer owns and occupies the home.
  • The county warns that if the debt remains unpaid 180 days after the residency/ownership change, full penalties and interest may be imposed and collection action may follow.
  • A surviving spouse may have continuation rights when the county’s stated age/occupancy conditions are met.

Mortgage and reverse-mortgage warning

The county advises checking the mortgage agreement before filing. A mortgage company may choose to pay taxes while it holds a lien, and the Tax Office warns that a reverse-mortgage transaction may require current and past-due taxes to be paid in full.

Payment plan and tax deferral are different. A quarter-payment plan splits current taxes into scheduled installments; a deferral postpones qualifying homestead taxes and carries its own interest and later-payment consequences.
2026 current-year update

2026 estimated taxes and Truth-in-Taxation notifications

Montgomery County’s official Tax Office page currently points taxpayers to the 2026 local property-tax database for estimated taxes while taxing units propose and adopt rates during August and September.

Use the estimate as planning information An estimated-tax notice is not the same thing as the final tax statement or current collection balance.
Review each taxing unit Rates are proposed/adopted by county, city, school, MUD, ESD and other governing bodies; MCAD does not set those rates.
Register for notifications if useful The county directs taxpayers to the Montgomery Truth-in-Taxation portal and says properties can be added to “My Properties” to receive updates.
Recheck after rates are adopted August/September estimates can change before final statements are issued.

Montgomery County TX Tax Collector FAQs

How do I pay Montgomery County TX property taxes online?

Use the official Montgomery County Tax Office ACT portal. Search by owner name, property address, account number, CAD reference number or fiduciary number, verify the property, tax year, current/prior balances, pending-payment status and amount, then choose the payment method and save the receipt.

What are the current Montgomery County online property-tax payment fees?

The Tax Office currently lists eCheck at $0.00, debit card at 1.00% with a $1 minimum, and credit card at 2.05% with a $1 minimum. Vendor convenience fees are non-refundable; verify the live checkout total before submitting.

What is the Montgomery County TX Tax Collector phone number, email and office hours?

For property-tax help, call 936-539-7897 or email tax@mctx.org. The main office is at 400 N. San Jacinto St., Conroe, TX 77301. Published hours are Monday-Friday, 8:00 a.m.-4:30 p.m., except county holidays.

How do I search Montgomery County TX appraisal records?

Use the MCAD property search for property ID, Geographic ID, Tax Office ID, owner, legal description, market/appraised value, exemptions, land, improvements, taxing units and protest information. Use the Tax Office portal for bill balances and payments.

What is the difference between the Montgomery County Tax Office and MCAD?

MCAD determines appraisal values, exemptions and appraisal records. The Tax Assessor-Collector collects taxes for accounts assigned to the Tax Office and records payments. The County Clerk maintains deeds, liens and other recorded real-property documents.

Does a zero Montgomery County Tax Office balance mean every local tax is paid?

Not necessarily. The official portal covers accounts collected by the Montgomery County Tax Office. Some MUD, utility or special-district taxes may use another collector, so compare MCAD taxing units with the jurisdictions on the county statement and any separate district bills.

When are Montgomery County TX property taxes due, and can I make a partial payment?

Tax notices are usually mailed in October and are due on receipt. January 31 is normally the final timely date, with delinquency beginning February 1. The Tax Office accepts partial payments, but an unpaid balance after January 31 generally accrues penalty and interest.

Does Montgomery County offer property-tax payment plans?

For current accounts, the Tax Office publishes one-time, pre-payment and qualifying quarter-payment routes. The quarter plan requires a residence homestead plus an age-65-or-older, disabled-person or disabled-veteran exemption and at least one-fourth paid by January 31, followed by March 31, May 31 and July 31 installments.

Where do I file a Montgomery County residence homestead exemption?

File Form 50-114 and supporting documents with Montgomery Central Appraisal District, not the Tax Office or Texas Comptroller. The form generally has an April 30 deadline, with specific late-filing rules for some residence-homestead, age-65, disabled and disabled-veteran applicants.

What does a Montgomery County residence-homestead tax deferral do?

A qualifying age-65-or-older, disabled person or disabled veteran may be able to postpone current or delinquent residence-homestead taxes by filing a deferral affidavit with MCAD. A deferral postpones rather than cancels taxes; the county says deferred amounts accumulate 5% interest per year and existing penalties, interest or attorney fees are not erased.
