Municipal property tax: checking whether the evidence is current
Municipal property tax is a recurring ownership obligation, so a document can be authentic and still be too old for a current sale or ownership decision. The relevant evidence is not merely a historic tax receipt. It is the current municipal record for the correct property, the correct owner or usufruct holder, the current tax year, the current assessed value and any unpaid balance that still attaches to the account. A source-freshness review therefore asks whether the evidence describes the position now, not whether it was once true.
Use the municipality that holds the property-tax account
GİB explains that property tax is paid to the municipality where the property is registered. That makes the municipal record the operational source for the individual property's assessment and payment status. A private spreadsheet, an old seller statement or a generic tax calculator may help organize a file but cannot replace the current municipal information. When a property is in a metropolitan area, do not assume that a payment made to another local body proves the account at the municipality responsible for the property itself.
Check the year before checking the amount
Property tax is annual. A receipt from the previous year may be perfectly valid for that year while saying nothing about the current year's assessment or later instalment. GİB states that the tax is paid in two instalments: the first during March, April and May, and the second in November. For a transaction in 2026, the file should therefore identify which 2026 instalment is due or has been paid and should not use a 2025 receipt as evidence that the current account is clear. If the sale moves into a new calendar year, refresh the municipal information again.
Confirm the taxpayer and the right attached to the property
Under the property-tax framework, the owner, the holder of a usufruct right where one exists, or in specified circumstances the person who possesses the property as owner may be the taxpayer. The name on a receipt must therefore be reconciled with the title and the relevant ownership period. A receipt in the name of a former owner may prove that former owner's payment, but it does not automatically establish the status of the current account after a later transfer. In co-ownership situations, the property and ownership structure should be matched to the municipality's account rather than inferred from one person's bank record.
Refresh the assessed value used in the transaction
The municipal property-tax value matters beyond the annual tax bill because TKGM requires the declared sale value in an ordinary title transfer not to be lower than the property-tax value. A stale value can therefore distort both the tax file and the transfer preparation. Obtain the current value for the transaction year and confirm that it refers to the exact parcel or independent unit. Do not substitute a real-estate market appraisal for the municipal tax value; the two documents answer different questions and can legitimately show different figures.
Check unpaid amounts before a title transfer
GİB's current property-tax guidance notes that a property with unpaid property tax generally cannot be transferred, subject to specified legal exceptions. For that reason, freshness becomes especially important close to a sale. A receipt proving that the first instalment was paid does not prove that no older debt, late amount or second instalment remains. Request a current account position and, where a payment has just been made, make sure the municipal system reflects it rather than relying only on the bank debit.
Treat exemptions and reductions as time-sensitive facts
An exemption, reduced-rate treatment or other special status should be supported by the rule and the taxpayer facts that make it applicable for the relevant year. Do not copy an exemption conclusion from a prior owner or a prior year without checking whether the statutory conditions still exist. A change in ownership, use, taxpayer circumstances or the governing year's rules can make an earlier conclusion obsolete even though the old municipal document is genuine.
What makes a property-tax source fresh enough?
For a current ownership or closing decision, the strongest file contains municipal information retrieved close to the decision date, the current-year tax value, the current account balance, receipts for instalments already paid, and a clear match to the title holder and property identifiers. It also records the retrieval date so that a later payment, new instalment or transfer can be recognized as a reason to refresh the evidence. Freshness is therefore a date-and-identity test, not a judgment based on how official a document looks.
