Smithtown Property Tax: Pay, Lookup & Calculate Online

The Town of Smithtown’s Receiver of Taxes collects real property taxes for the town, Suffolk County, school districts and other applicable taxing authorities during the regular town collection period.

The Receiver does not set the tax rates or decide property assessments. The right office depends on what you need.

Who handles each property tax issue?

Smithtown uses a county-authorized public tax-search service hosted at taxonline.egov.basgov.com. The service is linked directly from the town’s official website.

Four exact ways to search

Step-by-step: Find your Smithtown tax bill

1. Open the official tax lookup.

   Visit Town of Smithtown Tax Search . You can also reach this service through the town’s View/Pay Your Property Taxes page.

2. Identify which information you have.

   Choose Bill #, Tax Map #, Property Address or Owner Name. If you have the physical tax bill, the bill number or tax map number is usually the most precise.

3. Enter one search value.

   Follow the portal’s exact format. For an address, use the house number and street name without the street-type suffix.

4. Submit the search.

   Review the matching properties returned by the system.

5. Choose the correct tax bill.

   Compare the property address, owner information and tax map number before opening the result.

6. Review the bill details.

   The record can display the tax year, tax map, property information, tax amounts and available payment information.

7. Choose View Bill when you need the full statement.

   The bill details page directs users to View Bill for the property’s tax code. That tax code identifies the relevant rate in the town’s published rate sheet.

8. Check the current collection status.

   Current-year payment actions are available only during the authorized collection cycle. If the account is delinquent or belongs to a prior year, use Suffolk County’s payment service.

9. Save the information.

   Keep a PDF or printed copy of the statement, and record the bill number or tax map number for future searches.

What if the property is not found?

The town’s system explains that payments and adjustments during the authorized town collection period are generally updated within 24 hours after the Receiver processes them. After that period, the Suffolk County Comptroller maintains the relevant outstanding-tax information.

Smithtown mails real property tax bills once per year, normally around mid-December. The tax year runs from December 1 through November 30.

One consolidated town bill generally includes applicable Suffolk County, school district, town, fire district, library, lighting and other local taxes or charges.

How to find a PDF or printable bill

1. Search the property.

   Use the official Smithtown Tax Search link.

2. Select the matching bill.

   Confirm the address, tax map number and tax year.

3. Choose View Bill.

   Open the available full tax statement.

4. Review the tax code and line items.

   Identify the school district, assessments, charges and installments.

5. Print or save the document.

   Use your browser’s print or PDF-saving option.

Important fields on a Smithtown tax bill

Can you review older Smithtown tax bills?

The Smithtown search service provides access to available previous tax collections. It currently lists historical tax years in the bill-details system.

However, viewing an old bill is not the same as paying a past-due balance. The town’s payment service does not process prior-year taxes. For updated outstanding amounts, use Suffolk County.

During the town’s regular property-tax collection period, Smithtown accepts electronic property tax payments through its authorized online service.

Available payment methods include electronic check, debit card and major credit cards. A processing fee is charged by the payment service.

Smithtown online payment micro-steps

1. Open the town’s View/Pay Property Taxes page.

   Use the official Smithtown government page rather than an unfamiliar search-result payment link.

2. Select VIEW/PAY TAXES.

   The official page links to the town’s authorized property tax service.

3. Find your tax bill.

   Search with Bill #, Tax Map #, Property Address or Owner Name. Fill in only one field.

4. Open the correct property result.

   Compare the tax map number, address, owner and applicable tax year.

5. Review the available bill-details and payment options.

   Check the current amount and any payments already received. Payment actions are available only when that collection cycle is open.

6. Select the authorized payment action.

   Follow the current portal instructions. Do not attempt to process a prior-year balance through an older town bill.

7. Choose a payment method.

   Select eCheck, debit or an accepted card payment method offered on the screen.

8. Check the processing fee.

   Review the fee and final transaction total before authorizing the payment.

9. Submit the payment.

   Complete the transaction through the authorized processor.

10. Save your confirmation.

    Retain the receipt, transaction reference, payment date and tax bill number.

11. Check that the payment posts.

    Allow for normal processing time. Contact the Receiver before attempting an unnecessary duplicate transaction.

Smithtown online property tax processing fees

The current Smithtown tax portal lists the following charges on its bill-details payment screen.

Fees were verified from the town-authorized tax service. The checkout screen controls the fee for your actual transaction.

Calculate the online processing fee

Can you pay Smithtown property taxes by telephone?

The Receiver of Taxes publishes an automated telephone payment option during the authorized collection period.

How to pay in person

Visit the Receiver of Taxes at:

The Receiver lists cash, checks, money orders and accepted card payments as available in-person methods. Debit card payments have a listed $3.95 fee.

How to pay by mail

Make the check payable to Deanna Varricchio, Receiver of Taxes. Include the district, section, block and lot numbers on the check so the town can identify the parcel.

The Receiver says taxpayers who want a receipt by mail should include the entire current tax bill. Otherwise, a canceled check may serve as evidence of payment.

Does Smithtown have a payment drop box?

Yes. The Receiver describes a secure tax payment drop box at the side entrance of Smithtown Town Hall, available during the two main collection periods. Verify its current availability and cutoff rules before relying on it close to a deadline.

Smithtown’s tax year begins on December 1 and ends November 30 of the following year. Property tax bills are usually mailed once, around mid-December.

The bill can be paid in full or, when permitted, in two installments.

Why is the 2026 second-half deadline June 1?

The regular second-half date is May 31, but May 31, 2026 was a Sunday. The town’s tax page explicitly identifies June 1, 2026 as the adjusted penalty-free deadline for the 2025–2026 tax year.

There is a practical complication: the town’s online payment page still states that town online payments are unavailable after May 31. For a borderline transaction, taxpayers should confirm the accepted payment channel and cutoff with the Receiver rather than assuming the online portal remains open.

When will the next Smithtown tax bill arrive?

Following the town’s normal annual cycle, the next tax year starts December 1, 2026, and bills are generally mailed around mid-December.

The regular first-half statutory date is January 10, but January 10, 2027 falls on Sunday. Verify any officially adjusted 2027 deadline when the town publishes the new bill rather than assuming the standard date is the final legal cutoff.

What happens if your payment is late?

There is no general grace period beyond the applicable legal deadline. Penalties and interest may apply according to the installment and the collection period.

After the town’s annual collection closes, responsibility for outstanding balances transfers to Suffolk County.

Suffolk County states that delinquent taxes are subject to a 5% penalty plus interest of 1% per month calculated from February 1, under the applicable county collection rules. The county’s official calculator is preferable to manually estimating a delinquent payoff.

Smithtown publishes a detailed annual rate sheet. Its tax rates are stated per $1,000 of assessed or applicable taxable value, not simply as a percentage of a home’s estimated market value.

Your actual tax code determines which school, fire, police, library, lighting, ambulance, water or other districts apply.

Selected total rates by Smithtown tax code

These are selected rows from the official total-rate table. Some tax codes, including Hauppauge’s homestead and non-homestead variations, require additional district detail. Use the exact row matching your bill.

2025–2026 school district tax rates

School taxes are a significant component of many Smithtown bills. The town’s published school district rates are:

Other rates and charges shown in the official sheet

Not all the listed components apply to one property. The bill’s tax code and district information identify which levies belong to that parcel.

Why does a property in a village have a different rate?

Smithtown includes incorporated villages such as Nissequogue, Head of the Harbor and the Village of the Branch.

Some town-outside-village levies do not apply to properties within particular villages, and village taxes may be billed separately under applicable local procedures. This creates differences even when properties have similar market values.

This calculator uses selected official 2025–2026 total tax-code rates. Enter your property’s applicable assessed or taxable value and select the exact tax code shown on your bill.

The calculator gives a preliminary levy illustration. It is not a substitute for the town’s actual tax bill, because exemptions, different taxable bases, refuse charges and other adjustments can affect the final amount.

Worked example using official Smithtown tax code 48

Suppose a hypothetical property has an applicable taxable assessment of $4,000 and tax code 48. The town’s published 2025–2026 total rate for this code is $2,668.169 per $1,000.

This illustration excludes any additional flat refuse/disposal charges and parcel-specific exemptions or adjustments.

Why is the assessed value much lower than the home’s market value?

Smithtown is not necessarily assessing property at 100% of estimated market value. A local level of assessment is used to relate assessed values to full market values.

A homeowner must identify the assessment and relevant assessment percentage for the correct roll year. It would be incorrect to assume that a home with a $700,000 estimated market value is taxed on $700,000 at the town’s published per-$1,000 assessed-value rate.

New York State describes the general relationship as assessed value divided by level of assessment equals the assessor’s estimate of full market value. The applicable level must be obtained from the correct official assessment record.

Why actual taxes can exceed the preliminary rate calculation

Smithtown’s published tax-rate sheet separately includes refuse pickup and disposal charges based on applicable service categories, as well as special district levies.

As a result, a simple mill-rate calculation cannot necessarily reconstruct the full bill without those items.

Why school taxes are different in Kings Park, Commack and Smithtown

Each school district has its own tax levy and applicable tax base. Smithtown’s 2025–2026 rate sheet includes different school rates for Smithtown Central, Kings Park, Commack, Sachem, Hauppauge and Three Village.

You cannot determine the correct school tax from a postal ZIP code alone. Use the school district recorded on the actual tax bill.

When the town’s annual property tax collection period ends, outstanding balances are handled through the Suffolk County Comptroller.

This is especially important in October 2026. You may still be able to see a historical Smithtown bill online, but that does not mean the town is authorized to accept its delinquent payment.

Steps to pay an outstanding Smithtown bill

1. Find the original tax bill.

   Search the Smithtown tax portal and record the bill number, tax map number and tax year.

2. Open the Suffolk County Comptroller’s Payment Options.

   Use the official county service for prior-year and overdue taxes.

3. Select the county tax portal for prior-year taxes.

   Do not select unrelated payment programs.

4. Locate the correct account.

   Follow the county’s parcel ID, bill or property search instructions.

5. Check the updated balance.

   Review outstanding taxes, penalties, interest and other applicable charges.

6. Verify prior payments.

   Confirm any payment made to the town or county was credited correctly.

7. Review available payment methods.

   Suffolk County lists eCheck and major card payment options for outstanding taxes. Applicable fees are shown during checkout.

8. Submit and retain your receipt.

   Keep proof of payment and confirm posting with the county.

What if you do not know your Suffolk County parcel ID?

The county provides a Parcel ID Calculator. It uses information such as the town, district/SWIS number, bill item and Suffolk County tax map section, block and lot.

Can you pay only part of your delinquent property taxes?

Smithtown allows qualifying partial payments of at least $200 during its authorized collection period. The town states that penalties are imposed only on the unpaid balance after the deadline.

Suffolk County likewise describes a $200 minimum partial-payment option for outstanding property taxes. Partial payments reduce an outstanding balance but do not automatically resolve collection or tax-lien issues.

New York’s School Tax Relief program, commonly called STAR, provides school property tax relief to eligible primary-residence homeowners.

There are two different ways a homeowner may receive the benefit:

Basic and Enhanced STAR eligibility

Beginning in 2026, New York State updated certain Enhanced STAR eligibility and automatic-upgrade procedures. The state says it can automatically upgrade qualifying Basic STAR recipients who satisfy the age, income and other requirements.

How to register for the STAR Credit

1. Open New York State’s STAR website.

   Use the official New York STAR resource center .

2. Choose STAR registration.

   Open the state’s credit registration or Homeowner Benefit Portal.

3. Review homeowner eligibility.

   Confirm that the home is your primary residence and that your income meets the applicable limit.

4. Prepare property and owner information.

   Follow the state’s identification, address and ownership requirements.

5. Complete the state registration.

   Submit through the authorized state system.

6. Keep your registration confirmation.

   Review any further state notices or requests for information.

7. Check your STAR benefit separately.

   If you receive a STAR credit, remember that it is distinct from an exemption printed directly on a school tax bill.

For STAR registration questions, New York State publishes 518-457-2036.

Why does the town’s rate sheet include STAR information?

The 2025–2026 Smithtown tax rate sheet notes that school net levy amounts include money paid by New York State through the STAR program.

Smithtown also publishes annual district-specific STAR savings documents. The amount varies by school district, benefit type and applicable state rules.

Use your own tax bill or state benefit notice to determine the correct STAR amount for your property.

The Smithtown Assessor administers local property tax exemptions authorized under New York State Real Property Tax Law.

Qualifying for an exemption depends on the specific benefit’s ownership, use, income, disability, service or other statutory conditions.

Smithtown property tax exemption filing deadline

The town identifies March 1 as the annual exemption filing deadline for the applicable assessment year.

Smithtown’s guidance states that applications filed after March 1 may be effective for a following year rather than the current assessment year. Follow the specific program instructions, including any exceptions established by law.

How to apply for a local property tax exemption

1. Open Smithtown’s Property Tax Exemptions page.

   Review the categories administered by the Assessor.

2. Select the relevant exemption.

   For example, Senior Citizen, Veteran or Disability.

3. Read the full requirements.

   Check ownership, residence, age, income and other criteria.

4. Obtain the official application.

   Use the linked New York State or town-prescribed form.

5. Prepare documentation.

   Provide only the records required by that application.

6. Submit by the applicable deadline.

   Contact the Assessor if you are uncertain about eligibility.

7. Check the next assessment and tax bill.

   Confirm that any approved benefit appears as expected.

The Smithtown Assessor maintains the assessments, ownership records, property inventory and exemptions for approximately 43,000 parcels.

The town publishes its assessment rolls online, including the 2026 Final Assessment Roll.

How to locate your property on the 2026 Final Assessment Roll

1. Identify the property’s tax map number.

   Retrieve it from the annual tax bill or Smithtown’s tax-search portal.

2. Open the Assessment Rolls page.

   Select the official 2026 Final Assessment Roll section.

3. Choose the correct parcel-number range.

   The town divides the roll into several downloadable sections organized by the tax map sequence.

4. Open the relevant roll file.

   Search within the document for the parcel’s section, block and lot number.

5. Review the assessment information.

   Check the parcel’s assessed value, classification and listed exemptions.

6. Compare it with the prior assessment year.

   Determine whether values or exemption status changed.

2026 final assessment roll sections

These are the filing ranges published on Smithtown’s official 2026 Final Assessment Roll page. Some numbers are absent from the intervals because the roll follows the actual parcel sequence.

Smithtown’s annual property assessment calendar

The assessment roll and the town tax bill serve different purposes. The assessment establishes taxable property information; the subsequent tax warrant and levies determine the actual taxes.

If you believe Smithtown’s assessed value is incorrect, you can contact the Assessor for an informal review. If unresolved, you may file a formal complaint with the Board of Assessment Review.

How to prepare a Smithtown assessment grievance

1. Get the correct assessment record.

   Open the tentative assessment roll for the year under review.

2. Confirm the taxable status and valuation dates.

   Use the town’s annual calendar to identify the relevant property condition and valuation period.

3. Check the assessor’s recorded details.

   Review land, improvements, square footage, classification and other factors affecting the assessment.

4. Gather comparable sales or appraisal evidence.

   Smithtown recommends recent purchase contracts, comparable neighborhood sales or an appraisal based on the applicable valuation date.

5. Contact the Smithtown Assessor.

   Discuss the concern at 631-360-7560.

6. Review the formal grievance process.

   New York generally uses Form RP-524, Complaint on Real Property Assessment, for properties outside New York City and Nassau County.

7. File with the proper local office by Grievance Day.

   Follow the town’s exact submission and documentation instructions.

8. Keep the determination and filing records.

   If further review is permitted, follow the appropriate state or judicial procedures and deadlines.

Does appealing the assessment delay tax payment?

No automatic extension should be assumed. Assessment review concerns property valuation and classification. Tax collection deadlines are separate.

If a bill is due during an appeal, ask the collecting government how to satisfy current payment obligations.

How to update the tax bill mailing address

The town’s online services page includes a specific Change of Mailing Address for Tax Bills service. Use the official process when your correspondence address changes.

1. Open the Smithtown Online Services page.
2. Find the Receiver of Taxes section.
3. Select Change of Mailing Address for Tax Bills.
4. Complete the required owner and parcel information.
5. Submit according to the town’s instructions.
