Utah FSBO Tax Proration at Closing: How Property Taxes Are Split

When you sell your Utah home without a realtor, every line on the closing statement matters — and property tax proration is one that often surprises FSBO sellers. Understanding how utah fsbo property tax proration at closing works before you sign anything can prevent last-minute disputes and ensure you don't leave money on the table (or owe more than you expected).

What Is Property Tax Proration?

Property tax proration is the process of dividing the annual property tax bill between the seller and the buyer based on how many days each party owned the home during the tax year.

Utah property taxes are paid in arrears — meaning you pay this year's taxes next year. Because of this, at the time of closing, the current year's taxes haven't been paid yet. The title company calculates how much of the year you (the seller) owned the property, and you credit that amount to the buyer at closing. The buyer then pays the full bill when it comes due.

Example: If you close on August 4 and your annual property taxes are $3,600, you owned the home for roughly 216 days (January 1 through August 3). Your prorated share would be approximately $2,130, and that amount is credited to the buyer on the closing disclosure.

How Utah Property Taxes Are Structured

Utah property taxes are assessed and billed by each county's assessor's office. In Utah County (Provo, Orem, American Fork), Salt Lake County, Davis County, Weber County, and others, the tax year runs January 1 through December 31.

Tax bills go out in late October or November and are due by November 30 to avoid penalties. Because closings can happen any time of year, proration is almost always part of a Utah real estate transaction.

A few things specific to Utah FSBO sellers to know:

• Utah's circuit breaker program can reduce taxes for qualifying low-income or elderly homeowners, but this doesn't affect how proration is calculated at closing
• New construction properties may have incomplete assessed values — the proration might be based on a land-only value, which could be much lower than future bills
• Properties in rapidly appreciating counties like Washington County (St. George area) may have assessments that don't fully reflect the market value yet

Who Calculates the Proration?

In a Utah FSBO sale, the title company handles this calculation. As part of the closing process, they'll compute the daily tax rate and multiply it by the number of days you owned the property in the current calendar year.

For this reason, it's important to work with an experienced Utah title company — see our guide on how to work with a title company in a Utah FSBO sale for what to expect.

The formula used is generally:

Annual Tax ÷ 365 = Daily Tax Rate
Daily Tax Rate × Days Seller Owned in Tax Year = Seller's Prorated Share

This amount shows up as a credit to the buyer and a debit to the seller on the ALTA settlement statement.

What If the Tax Amount Is Unknown?

Tax bills are typically unavailable until late October or November. For closings earlier in the year, the title company will estimate based on the prior year's tax bill (sometimes with a small adjustment factor of 105–110% to account for potential increases).

This estimated proration is standard in Utah FSBO contracts. When you use the Utah Real Estate Purchase Contract (REPC), Section 4 addresses how prorations are handled. If actual taxes differ from the estimate, the parties may need to reconcile after the fact — though most Utah title companies use conservative estimates to avoid this.

Watch for this: If your home was recently remodeled, had a significant value increase, or you appealed your assessment, the prior year's bill may not accurately reflect what the buyer will actually owe. You and the buyer may want to negotiate a slightly higher estimated proration buffer.

Taxes Already Paid vs. Taxes Not Yet Due

There are two scenarios you could be in when you close:

1. You already paid the prior year's tax bill (November payment)

This is common for sellers who close in the spring or summer. You paid last year's taxes in full in November. The current year's taxes are not yet billed. In this case, the title company simply prorates the estimated current-year amount and credits the buyer.

2. You have an outstanding tax balance

If you close in November or December and the bill has already been issued, the title company will require the bill to be paid at or before closing. The buyer cannot take title with delinquent taxes — a lender certainly won't allow it, and even in cash transactions it creates title issues.

HOA Dues and Mello-Roos: Different Animal

Property tax proration is separate from HOA assessments and dues, which are also typically prorated at closing. Some Utah communities — particularly newer developments in Eagle Mountain, Saratoga Springs, and parts of St. George — include special assessment districts that function similarly to taxes. These will also be prorated.

If your property has special assessments, ask the title company to identify them separately on the closing statement so you know exactly what you're paying.

Common FSBO Mistakes Around Tax Proration

1. Assuming you'll owe nothing because you "already paid" taxes

Even if you paid last year's bill in November, you still owe proration for the current year up through closing. This often catches new FSBO sellers off guard.

2. Not reviewing the closing disclosure carefully

The closing disclosure (ALTA/HUD-1 settlement statement) will show the exact proration amount. Review it the day before closing and compare it to what was estimated in your contract. A competent Utah title company will get this right, but errors happen.

3. Using the wrong year's tax amount

If your property was recently remodeled, reassessed, or sold in a tax appeal, the prior year's amount may be significantly different from the current year. Ask your county assessor's office for the current assessed value if you're uncertain.

4. Overlooking partial-year exemptions

Utah offers a primary residential exemption (the "45% exemption") that reduces the taxable value of your home. This is already built into your tax bill, so proration calculations should automatically account for it — but confirm with the title company that they're using your actual tax bill, not a raw assessed value.

How to Confirm the Numbers Are Right

Before closing day, do this:

• Pull up your county's tax payment portal (most Utah counties have online lookup tools) and note your current assessed value and the prior year's tax amount
• Ask the title company what per diem tax rate they used in their proration calculation
• Verify the number of days used in the calculation — make sure they're counting from January 1 to the day before closing (not including the closing date itself, which belongs to the buyer per standard Utah practice)

If anything looks off, raise it before you sign. Title companies are used to these questions from FSBO sellers and will walk you through it.

Summary: What You'll Owe at Closing

Here's a quick checklist for Utah FSBO sellers on tax proration:

• Yes, you will owe prorated taxes at virtually every Utah closing — it's how the arrears system works
• The amount will appear as a debit to you and a credit to the buyer on your settlement statement
• The title company calculates it — confirm the numbers are based on your actual tax bill, not a generic estimate
• Special assessment districts in newer Utah communities may add additional prorated amounts
• If you close late in the year and your bill is already issued, it may need to be paid at closing

Tax proration is straightforward once you understand the mechanics, but it's one of the items worth reviewing carefully before signing your final closing documents.
