Big Lake Property Tax Records

Big Lake property tax records are maintained by the Matanuska-Susitna Borough, which handles all property assessment and tax billing for this census-designated place in the Mat-Su Valley. Big Lake is not an incorporated city, so the borough is the only local property tax authority for parcels in the area. You can search Big Lake property tax records online through the borough's property portal at myproperty.matsugov.us, which gives you free access to assessed values, parcel details, and account information. The Mat-Su Borough conducts annual reassessments with a January 1 assessment date and manages a large and growing parcel database across the valley.

Big Lake Property Records Online

The Matanuska-Susitna Borough property portal at myproperty.matsugov.us is the main online tool for searching Big Lake property tax records. The system is free to use and does not require registration. You can search by owner name, parcel number, or site address. Each record shows the parcel's assessed value for the current tax year, the legal description, any exemptions on file, and the tax district the parcel falls in. Big Lake parcels are searchable by their street addresses or through the community name as a filter, depending on how the borough has the parcels tagged in the system.

The property portal reflects the January 1 assessment for the current tax year. New construction or property transfers after that date will appear in the system after the next annual reassessment.

Big Lake's average property tax bill of approximately $2,667 is below the borough-wide average, which reflects the mix of residential properties in the community. The Mat-Su Borough conducts annual reassessments rather than using a multi-year cycle, which means values are reviewed and updated every year. That keeps Big Lake assessments relatively current with market changes in the fast-growing Mat-Su Valley.

For questions about a specific Big Lake parcel, contact the Mat-Su Borough Assessment Department at 350 E. Dahlia Avenue, Palmer, AK 99645. The phone number for real property questions is (907) 861-8642. For personal property accounts, call (907) 861-8637. Additional property information resources are available at matsu.gov/property-tax-and-value.

Note: The Mat-Su Borough also allows property owners to submit exemption applications, value appeals, and other forms online or by mail to the Palmer office. Big Lake residents do not need to visit Palmer in person for most routine requests.

How Big Lake Property Tax Is Assessed

Big Lake is a census-designated place within the Matanuska-Susitna Borough, which means there is no city-level property tax. The KPB mill rate is the only local rate that applies to Big Lake parcels, though service area surcharges may also apply depending on which borough service areas cover a specific parcel. Service areas fund local services like fire protection and road maintenance, each carrying a small additional mill rate added on top of the base borough rate. Your assessment notice will list which service areas apply to your Big Lake property.

State law requires that all Mat-Su Borough property be assessed at full and true market value as of January 1 under AS 29.45.110. The Mat-Su Borough uses annual reassessment to keep values current. Assessors review sales data from the Big Lake area and surrounding Mat-Su communities each year to update values. The borough's assessing staff also has the right to inspect any taxable property under AS 29.45.130 to verify condition and features. Physical field reviews are part of the reassessment process, though not every parcel is visited every year.

The Matanuska-Susitna Borough Assembly sets the mill rate each year as part of the borough budget process. Under state law, the total rate for borough levies cannot exceed 30 mills under AS 29.45.090. The current mill rate for Big Lake parcels is set annually and applies to each parcel's assessed value after any exemptions are subtracted. The Mat-Su Borough's property tax and value page at matsu.gov/property-tax-and-value lists the current rates and any recent changes.

Big Lake Property Tax Bills and Payment

The Mat-Su Borough mails property tax bills in the spring after the assessment and appeal process concludes. Big Lake property owners should watch for their bill and pay by the due dates listed on it. The borough sets specific due dates each year, and paying on time avoids penalties and interest. For current due dates and payment instructions, check the borough's property tax page or call the assessment department. Both the real property and personal property phone lines are at the Palmer office.

Payment options include online payment through the Mat-Su Borough's systems, mail to the borough office at 350 E. Dahlia Avenue in Palmer, or in person at the office. Big Lake residents who cannot travel to Palmer can use the online or mail payment options to handle their tax bill without a trip. The average Big Lake tax bill of around $2,667 falls below the Mat-Su average, but individual bills vary widely based on parcel size, property type, and assessed value.

Delinquent accounts in the Mat-Su Borough accrue interest and penalties after the payment deadline. Long-term delinquency can result in a tax lien being filed against the property. That lien becomes public record through the recording system and must be resolved before the property can be sold or refinanced. Big Lake property owners who are behind on taxes should contact the borough's assessment or finance office to ask about payment arrangements before a lien is filed.

Big Lake Property Tax Exemptions

Big Lake property owners qualify for Mat-Su Borough exemption programs under the same rules that apply across the entire borough. The mandatory senior citizen and disabled veteran exemption required by AS 29.45.030 removes the first $150,000 of assessed value from the tax bill for qualifying owners. To qualify, you must be 65 or older or be a disabled veteran with a service-connected disability rating of at least 50 percent. The property must be your primary residence. Alaska reimburses the Mat-Su Borough for revenue lost to this program, so claiming the exemption does not reduce borough services.

Optional exemptions under AS 29.45.050 may also be available for Big Lake residents. These can include a homestead exemption on a primary residence of up to $75,000 and personal property exemptions in some cases. Contact the Mat-Su Borough Assessment Department at (907) 861-8642 to find out which optional programs are currently active and what the application deadline is for the current year. Exemption applications must be submitted before the spring deadline each year to count toward that year's tax bill. Missing the deadline means waiting another full year to apply.

If you recently purchased a Big Lake property and want to establish your own exemption eligibility, apply with the borough directly. Exemptions do not carry over automatically to new owners, even if the previous owner qualified. The assessment department staff in Palmer can tell you what documentation you need and how to complete the application.

Appealing a Big Lake Property Assessment

If you receive a Mat-Su Borough assessment notice for your Big Lake property and you believe the value is too high, you have 30 days from the notice date to file an appeal with the MSB Board of Equalization under AS 29.45.190. Your written appeal must state the grounds. You can challenge the value as excessive compared to market sales in the Big Lake area, argue that your property was treated unequally compared to similar parcels, or point to a factual error in the parcel record. Appeals about the mill rate or tax policy are not handled by the board. Those go to the Mat-Su Borough Assembly.

Before filing the formal appeal, call the real property assessment line at (907) 861-8642 and ask how your Big Lake value was determined. The assessor can walk you through the data and method used. If an error is present, such as incorrect square footage or wrong construction type, the assessor can issue a corrected notice, which gives you a new 30-day appeal window. If the department stands by the original value and you still disagree, file the written appeal before the deadline and prepare your evidence for the board hearing. Recent sales of comparable Big Lake parcels are the strongest evidence to bring to a board hearing.
