Pay Montgomery County Texas property tax online, by mail or in office
Montgomery County accepts several payment methods. The most important rule is to pay the correct account before January 31 if you want to avoid penalty and interest starting February 1.
Online payment
Use the official tax portal. Review debit/credit card fee, owner, address, year and total before submitting.
Mail payment
Mail to Tammy J. McRae, 400 N. San Jacinto St., Conroe, TX 77301. If mailing in late January, make sure the postmark is no later than January 31.
Office payment
Montgomery County says office payments may be made by cash, check, money order and debit/credit card, with a nominal card fee.
1
Look up the bill first
Never pay from only a memory of the amount.
▾
Open the official Tax Statement and Online Payment portal. Confirm the property account and tax year before choosing a payment method.
2
Pay early if mailing
Postmark matters near the January deadline.
▾
Montgomery County says payments are posted according to postmark. If mailing in late January, make sure the envelope is postmarked by the post office no later than January 31.
3
Use partial payments carefully
Partial payment does not stop all penalties after Jan. 31.
▾
Montgomery County says partial payments are accepted, but any remaining balance not paid by January 31 begins to accrue penalty and interest. For mailed partial payments, write the property account number and “partial payment.”
4
Save receipt and confirmation
Useful for mortgage, closing and payment disputes.
▾
Save payment date, amount, account number, confirmation number, tax year and receipt. This is especially important if a mortgage company, title company or buyer/seller closing credit is involved.
Calculate a Montgomery County property tax estimate
Your official tax statement is final, but this formula helps explain why the bill changed.
Simple tax estimate formula
Estimated tax = taxable value ÷ 100 × combined tax rate + penalty/interest if delinquent.
| Bill Part | What It Means | Where To Check |
|---|---|---|
| Market value | MCAD’s estimate of property value | MCAD property search |
| Exemptions | Reductions such as homestead, over-65, disability or veteran exemptions | MCAD / Texas Comptroller |
| Taxing units | County, school district, city, MUD/utility or special districts | Tax statement and tax-rate page |
| Penalty / interest | Late charges beginning after delinquency | Tax Office portal |
Wrong name, address, owner, exemption or value: Tax Office or MCAD?
Montgomery County’s FAQ is clear: the Tax Office handles tax bills and collections, while MCAD handles value, exemptions and appraisal records.
| Problem | Contact First | What To Prepare |
|---|---|---|
| Wrong owner/name/address | MCAD | Tax statement, deed/closing document, ID, mailing address proof |
| Sold property but still getting statement | MCAD | Closing statement, deed, sale date, property account |
| Mortgage escrow should pay | Mortgage company | Tax statement with loan number, escrow account number |
| High appraised value | MCAD / ARB protest | Comparable sales, repairs, photos, appraisal notice, protest evidence |
| Payment not posted | Tax Office | Receipt, confirmation number, date, amount, account number |
Montgomery County homestead and property tax exemptions
Exemptions can reduce taxable value, but they are handled through the appraisal district and state law rules, not the payment portal.
General homestead
Texas Comptroller guidance says a residence homestead exemption can lower taxes, including the required school district homestead exemption.
Over-65 / disability
May add extra savings or payment options if eligible. Verify status through MCAD before assuming the bill is correct.
Veteran exemptions
Disabled veteran and surviving spouse rules can be valuable but document-heavy. Apply through MCAD with required proof.
1
Check your MCAD account first
Look for existing exemption codes.
▾
Open Montgomery Central Appraisal District and review the property record. Check whether homestead, over-65, disability or veteran exemptions already appear.
2
Apply before the general deadline
Texas general exemption deadline is before May 1.
▾
Texas Comptroller guidance says the general deadline for filing an exemption application is before May 1, and the chief appraiser determines qualification. Check MCAD for exact local forms and submission options.
3
Re-check the tax bill after approval
Approval must reflect in taxable value.
▾
After MCAD approves an exemption, compare the updated property record and the Tax Office statement. If the bill still appears wrong, contact MCAD and the Tax Office with the account number and exemption approval details.
How to protest a Montgomery County appraised value
Do not wait for the tax bill if the value is wrong. Protests happen through the appraisal process before the bill is due.
Usual Texas protest deadline
Texas Comptroller guidance says the usual protest deadline is May 15 or 30 days after the appraisal district mails the notice, whichever is later.
What you can protest
Value, unequal appraisal, exemption denial, ownership/error issues, property description problems and certain appraisal district actions.
Evidence that helps
Comparable sales, photos, repair estimates, inspection issues, flood/drainage problems, dated condition proof and correction records.
Pay undisputed taxes if needed
If a protest or correction continues near delinquency, ask Tax Office/MCAD what amount must be paid to avoid added charges or lost rights.
1
Download or review your appraisal notice
Find value, exemption and deadline details.
▾
Use MCAD to review your appraisal record and notice information. Note the mailing date, deadline and property account number.
2
File the protest before the deadline
Late protest rights are limited.
▾
Follow MCAD’s protest process. Texas Comptroller guidance says a notice of protest is sufficient if it identifies the property, property owner and a subject showing dissatisfaction with an appraisal district decision.
3
Prepare evidence like a checklist
Make it easy for the reviewer to understand.
▾
Use a short packet: property account, requested value, comparable sales, repair estimates, dated photos, flood/damage notes and a simple one-page explanation. Avoid emotional arguments; focus on market value and unequal appraisal evidence.
