Bookkeeping for property tax prorations at closing

Property tax prorations at closing distribute the current year's taxes between the buyer and seller based on the closing date. For bookkeeping, you record the amount you pay or receive as an adjustment to the property's cost basis or an expense. This is not tax advice.

What are property tax prorations?

Property tax prorations are calculations made at closing to allocate property tax expenses fairly between the buyer and the seller. The goal is that each party pays for the days he or she owned the property during the tax period.

Since property taxes are often paid in arrears or advance for a full year, a credit or debit is applied on the closing statement. This ensures neither party unfairly shoulders the entire year's tax burden.

The prorated amount depends on the closing date, the tax period, and whether taxes have already been paid for the current period. Your closing statement will show these specific adjustments.

Who pays what and when

If the seller has already paid the full year's property taxes, he or she will receive a credit for the days the buyer will own the property. This means you, as the buyer, reimburse the seller for your share.

If the taxes have not yet been paid for the current period, the seller will owe you a credit for the days he or she owned the property. You, as the buyer, then typically pay the full tax bill when it is due.

The title company or closing attorney calculates these amounts based on local tax schedules and the agreed-upon closing date. Always review this section of your closing disclosure carefully.

Recording prorations as the buyer (acquiring investor)

When you acquire a property, any property tax proration where you receive a credit from the seller is generally treated as a reduction in your acquisition costs. This lowers your cost basis for the property.

If you pay the seller for taxes he or she pre-paid, that portion attributable to your ownership period is treated as an expense, often categorized as a property tax expense.

Keep the closing statement as your primary record. It clearly outlines the prorated amounts and how they were applied. This helps you track what was paid and by whom. This is not tax advice.

Recording prorations as the seller (disposition)

If you are selling a property, and you owe the buyer a credit for taxes you should have paid, this reduces your proceeds from the sale. It's an expense related to the sale.

If you receive a credit from the buyer for taxes you pre-paid, this increases your cash proceeds. This portion might be recorded as a recovery of a previous expense or an adjustment to your tax expense for the period.

Again, your closing statement is your official record. It should accurately reflect the cash flow and allocation of tax responsibility. This is not tax advice.

Impact on your property's cost basis

The property's cost basis is what you paid for it, plus acquisition costs, and less any prorations you received. An accurate cost basis is vital for calculating capital gains when you eventually sell.

If you received a tax credit at closing because the seller was responsible for taxes up to that point, that credit effectively reduces your total cost of acquiring the property.

Consult with your accountant for specific guidance on how these prorations affect your property's basis and your overall tax liability. Every situation can be slightly different. This is not tax advice.

Why accurate records matter

Maintaining precise records of all closing adjustments, including tax prorations, is crucial for accurate financial reporting and tax compliance. These details can impact your profit calculations significantly.

In case of an audit or when preparing your tax returns, having clear documentation of these prorations justifies your expense deductions and cost basis calculations.

Use a consistent bookkeeping system to log these transactions immediately after closing. Do not rely on memory or disorganized paperwork.

Questions people ask

Do I need a special account in my books for prorations?

Not necessarily a special account. Prorations are typically recorded against the relevant expense (like property taxes) or as an adjustment to the property's asset account. Your chart of accounts might have a 'property tax expense' account.

What if the prorated amount seems wrong on the closing statement?

Immediately bring it to the attention of your title company or closing attorney. They can review the calculations and make any necessary corrections before closing or reconcile it shortly after. Always check before you sign.

How do prorations affect my cash flow at closing?

Prorations directly impact the amount of cash you need to bring to closing or the amount of cash you receive. A credit to you means less cash out or more cash in, and a debit means more cash out or less cash in.
