Cook County Tax Proration: What the Closing Credit Covers
Cook County tax proration reduces cash needed at closing, but does not set your next bill. Check exemptions, escrow funding and reproration terms.

Pittsburgh transfer tax affects closing cash. Compare city and Baldwin Borough rates, contract splits, and a hypothetical $300,000 purchase.
A taxable purchase subject to both City of Pittsburgh and Pittsburgh School District taxes carries a combined transfer tax of 5% as of August 31, 2026. The amount it adds to your closing cash depends on the purchase contract. An equal split assigns 2.5% of taxable value to the buyer, but equal sharing is not mandatory.
In the hypothetical $300,000 purchases below, the buyer’s transfer-tax share is $4,500 higher in Pittsburgh/Pittsburgh School District than in Baldwin Borough, assuming both contracts split all transfer taxes equally. Account for that difference before signing an offer.
Realty transfer tax is a tax on transferring an interest in real estate. For the Pittsburgh city-and-school-district combination used here, the components are:
| Taxing authority | Rate |
|---|---|
| Commonwealth of Pennsylvania | 1% |
| City of Pittsburgh | 3% |
| Pittsburgh School District | 1% |
| Combined transfer tax | 5% |
These components appear in the city’s 2026 operating budget, approved December 21, 2025. Transfer taxes are separate from annual property taxes.
The city’s 3% consists of two levies: 1% under Chapter 255 and an additional 2% under Chapter 256. The latter rate took effect January 1, 2020. Reading only one chapter can therefore understate the city component.
For an ordinary sale between independent buyers and sellers, Pennsylvania bases taxable value on the full agreed consideration. In the resale example below, that is the $300,000 purchase price. A smaller mortgage or larger down payment does not reduce that amount. Transactions involving surviving liens or other consideration require a more specific calculation under the state valuation rule.
Start with the property’s actual municipality and school district. Ask the settlement agent to confirm both against the deed and parcel records. A mailing address or listing’s location label is insufficient: under Pittsburgh Code §255.02, the city levy follows where the real estate is situated, with an allocation for property partly outside the city boundary.
Baldwin Borough provides a documented comparison. Its 2026 budget, adopted at the December 16, 2025 council meeting, identifies a 0.5% borough transfer tax and a separate 0.5% Baldwin-Whitehall School District transfer tax. Adding Pennsylvania’s 1% produces a 2% combined rate.
Other suburbs require their own rate checks. Confirm each property’s municipal and school components separately when comparing housing affordability and purchase costs.
No. Buyers and sellers can agree on how to divide the payment. The city’s 2026 budget describes equal sharing as typical, but that custom does not establish what your contract requires.
Read the transfer-tax clause for the buyer’s share of both state and local taxes. A verbal description such as “we each pay our half” cannot substitute for the signed terms.
Contractual allocation and legal liability are separate. For Pennsylvania’s tax, buyer and seller are jointly and severally liable: the Commonwealth can seek the unpaid state tax from either, despite their private payment arrangement.
Pittsburgh’s Chapter 255 and Chapter 256 also identify the person accepting the transfer document as liable for city tax. A seller’s promise to pay therefore does not establish that the buyer has no tax exposure. Have a Pennsylvania real estate attorney resolve an unclear allocation or claimed exemption before signing.
This hypothetical compares ordinary, fully taxable resales. Each property has a $300,000 price and taxable value, with no surviving seller liens or additional consideration. Both contracts expressly split all transfer taxes equally.
| Transfer-tax calculation | Pittsburgh / Pittsburgh School District | Baldwin Borough / Baldwin-Whitehall School District |
|---|---|---|
| State: 1% | $3,000 | $3,000 |
| Municipality: 3% / 0.5% | $9,000 | $1,500 |
| School district: 1% / 0.5% | $3,000 | $1,500 |
| Total transfer tax | $15,000 | $6,000 |
| Buyer’s agreed 50% share | $7,500 | $3,000 |
These calculations use the rates documented in the Pittsburgh and Baldwin Borough budgets, plus the state levy.
To calculate the remaining cash to close, assume both buyers make a 10% down payment, take a $270,000 mortgage and have already paid a $6,000 earnest-money deposit fully available as a closing credit. Allow $8,000 for all other buyer closing costs, prepaids and initial escrow funding, all payable at closing. Assume no additional credits, financed closing costs or net prorations.
The $8,000 is an illustrative allowance, not a local fee estimate. Holding it constant isolates the transfer-tax difference.
| Buyer’s cash calculation | Pittsburgh example | Baldwin Borough example |
|---|---|---|
| Down payment | $30,000 | $30,000 |
| Other costs, prepaids and escrow funding | $8,000 | $8,000 |
| Buyer’s transfer-tax share | $7,500 | $3,000 |
| Less deposit already paid | −$6,000 | −$6,000 |
| Remaining cash to close | $39,500 | $35,000 |
The credited deposit reduces the amount still due at closing; it does not reduce the tax. If the Pittsburgh contract instead assigns the entire $15,000 transfer tax to the buyer, the same assumptions produce $47,000 in remaining cash to close.
Certain transfers, including qualifying transfers between specified relatives, can be excluded from state tax. Eligibility depends on the transaction and its conditions under Pennsylvania’s exclusions regulation.
New construction also needs separate review. Under specified contractual relationships, taxable value includes contracted-for improvements as well as the land. Before applying the resale calculation to a lot-and-building arrangement, check the construction-contract rule.
For a mortgage purchase using a Closing Disclosure, find the transfer taxes under “Taxes and Other Government Fees.” Under the CFPB’s April 8, 2026 version of Regulation Z, the disclosure identifies the taxing authorities and assigns charges to borrower-paid, seller-paid or other payment columns. Check those allocations against the contract, then reconcile the deposit and other credits in the cash-to-close calculation.
Use the closing-cost calculator for the broader budget, then reconcile its allowance with the property-specific tax calculation. Include the buyer’s transfer-tax share only once: adding it to a closing-cost subtotal that already contains it overstates the cash needed.

Estimate buyer closing costs and total cash to close.
As part of your homebuying preparation, request an estimate that names the municipality, school district, taxable value and contractual allocation. Those four entries let you compare the transfer-tax assumptions behind competing purchase budgets.
As of August 31, 2026, a fully taxable $300,000 purchase subject to both City of Pittsburgh and Pittsburgh School District taxes has a combined transfer-tax bill of $15,000. If the contract splits it equally, the buyer pays $7,500; a different allocation changes the buyer’s share. The combined rate is documented in the city’s 2026 budget.
No. The parties can agree on how to divide payment, but their agreement does not limit the Commonwealth’s collection rights against jointly and severally liable parties. Read the purchase contract’s state and local transfer-tax provisions. 61 Pa. Code §91.111
For an ordinary resale, the starting point is the total agreed consideration for the property, not the buyer’s mortgage amount. Surviving liens and other consideration can affect taxable value. Pennsylvania’s valuation rule
No. A deposit credited at settlement reduces the remaining cash to close; it does not lower the property’s taxable consideration. Check that it appears correctly in the Closing Disclosure’s deposit and cash-to-close calculation.
