How to Calculate Property Tax Proration

Property tax proration divides the annual tax bill fairly, ensuring buyer and seller pay only for their ownership period. Here's how the real estate tax split works:

  1. Tax Period: Is it a calendar year (Jan 1 - Dec 31) or a fiscal year (e.g., Jul 1 - Jun 30)?
  2. Daily Rate: Annual Tax ÷ Days in Year (365/366). This tool uses actual days.
  3. Ownership Days: Count seller's days (start of year to closing) and buyer's days (rest of year). Adjust based on who owns closing day.
  4. Calculate Shares: Multiply Daily Rate × Ownership Days for each party.
  5. Closing Adjustment: The final amounts appear as credits/debits on the closing statement (like the Closing Disclosure, formerly HUD-1) to settle the buyer tax proration and seller tax credit.

Remember: Local customs vary. Confirm with your closing agent.

Video Explanation of Proration

"Proration is really important because it keeps things fair and helps prevent arguments or confusion about who has to pay what... which helps make the whole process go smoothly."

– Maggie Deo, Licensed Real Estate Instructor

Calendar Year vs. Fiscal Year Tax Systems

Understanding the tax year basis is crucial for accurate proration:

  • Calendar Year: Runs Jan 1st - Dec 31st. Select this option and the calculator uses Jan 1st of the closing year as the start.
  • Fiscal Year: Covers a different 12-month period (e.g., Jul 1st - Jun 30th). Select this and enter the specific start date of the applicable tax year.

Example Calculation Walkthrough

Example Scenario:

  • Annual Property Tax: $4,200
  • Tax Year Basis: Calendar Year (Starts Jan 1st, 2026 - leap year, so 366 days)
  • Closing Date: September 10th, 2026
  • Who Owns Closing Day: Seller

Steps:

  1. Daily Tax Rate: $4,200 / 366 days = $11.4754 per day
  2. Seller's Days: Jan 1st to Sep 10th (inclusive) = 254 days
  3. Buyer's Days: 366 days - 254 days = 112 days
  4. Seller's Share: 254 days * $11.4754/day = $2,914.75
  5. Buyer's Share: 112 days * $11.4754/day = $1,285.25

Result: Seller's responsibility is $2,914.75, buyer's is $1,285.25. The closing statement adjusts based on payments.

FAQs About Tax Proration at Closing

How do you prorate taxes at closing?

Calculate the daily tax rate (annual tax / days in tax year). Multiply the daily rate by the number of days the seller owned the property and the number of days the buyer will own it within that tax year. Adjustments appear as credits/debits on the closing statement.

What if taxes are already paid by the seller?

If the seller prepaid taxes covering time the buyer will own the property, the buyer usually credits the seller for that portion at closing. This often results in a seller tax credit on the statement.

Who pays the property taxes when a home sells?

Both parties pay their proportional share for the tax year based on ownership duration. This financial real estate tax split is settled at closing via credits.

What’s the difference between calendar and fiscal year tax systems?

A calendar tax year is Jan 1 - Dec 31. A fiscal tax year is any other 12-month period (e.g., Jul 1 - Jun 30). This affects the start date used for counting ownership days in the buyer tax proration.

What happens if the closing is delayed?

If the closing date changes, the proration calculation must be redone using the new date to ensure the seller and buyer days are accurate. A delay shifts the financial responsibility slightly.

How are proration credits shown on the Closing Disclosure (formerly HUD-1)?

Tax prorations typically appear as credits on the Closing Disclosure. If taxes are paid in arrears, the seller usually credits the buyer for the seller's portion of unpaid taxes. If taxes are prepaid, the buyer credits the seller for the portion the buyer will benefit from.

this 0:34 video will help you no matter what state 0:36 you're in since math is a universal 0:38 language after all okay let's get back 0:41 to prorations whether it's annual taxes 0:43 monthly rent or even HOA payments 0:46 understanding pration is crucial for 0:48 Success on your exam we'll explore 0:51 pration methods for both 365 day and 0:55 360-day calendars so let's Jump Right In 1:08 [Applause] What is Proration 1:11 pration is an important part of buying 1:13 or selling a house it's when the costs 1:16 like property taxes HOA fees utility 1:20 expenses and or rent payments are 1:22 divided fairly between the buyer and the 1:25 seller based on how long each own the 1:28 property this helps make sure that that 1:30 everyone pays their fair share and 1:32 avoids any problems pration is really 1:35 important because it keeps things fair 1:37 and helps prevent arguments or confusion 1:40 about who has to pay what it makes sure 1:43 that everyone involved in the sale pays 1:46 the right amount of money which helps 1:49 make the whole process go smoothly for 1:52 pration problems there are three easy 1:55 steps to follow and five rules to 1:58 Counting dates let's start with the five 2:01 rules to Counting dates number one if 2:04 the question does not State how many 2:06 days to use you are to use the 365 day 2:10 calendar number two if it's for a 365 2:13 day calendar and you're prating a 2:16 monthly fee like a rent or an HOA 2:18 payment you will divide by the number of 2:21 days in the month given for closing so 2:24 if the closing is scheduled for sometime 2:26 in May you'll use 31 days since May has 2:29 31 days and if the closing is in 2:32 February you guessed it you'll use 28 2:35 days and so on and so forth number three 2:39 if it's a 360-day calendar you are to 2:42 use 30 days for each month and yes even 2:45 February 2 number four if closing day 2:49 belongs to the seller you count the day 2:51 of closing in the total days in step two 2:54 which we'll discuss next number five if 2:57 the day of closing belongs to the buyer 2:59 you you do not count the day of closing 3:02 which we'll also discuss next now that 3:04 we've gotten the rules of the game out 3:06 of the way let's go over the three easy 3:09 steps to solving probation questions 3:13 step one is to find the daily rate 3:16 basically how much will it cost per day 3:19 simply divide the total amount of the 3:22 yearly tax by either 360 days or 365 3:27 days to get your daily amount step two 3:30 is to find out how many days the seller 3:32 owns the property for that year or month 3:36 remember if the closing day belongs to 3:38 the seller you will count the closing 3:41 day as part of your total days if the 3:43 closing day belongs to the buyer you do 3:47 not count the closing day in your total 3:49 days also as we discussed earlier if it 3:53 says to use 360 calendar days each month 3:57 will have a total of 30 days days and if 4:00 it says to use 365 days you'll use the 4:03 number of days for each month don't 4:05 worry I'll show you a little hack on how 4:08 to know the amount of days each month 4:10 has a little later on in the video and 4:13 finally step three is to just multiply 4:17 step one by step two and there you have 4:20 it super easy okay now here's the hack I 4:23 promised you on how to know the total 4:25 days each month has to find the number 4:28 of days each month has you're going to 4:30 use the knuckle method where each 4:33 knuckle counts for 31 days and the 4:36 indentation between the knuckles is 28 4:39 days or 30 days so it'll look something 4:43 like this January has 31 days February 4:48 has 28 days March has 31 days April has 4:53 30 days May has 31 days June has 30 days 5:00 July has 31 days then you start all over 5:04 August has 31 days September has 30 days 5:10 October has 31 days November has 30 days 5:15 and December has 31 days all right now 5:18 that we have all that information on how 5:20 to solve these types of problems let's 5:23 Jump Right In and go over a few 5:25 questions so you could get some practice 5:28 and perfect your pration calculation 5:33 [Music] 5:36 skills first up let's work out some Examples 5:39 problems using the 365 day probation 5:41 method for annual 5:46 fees number one Alex sold his property 5:50 on June 15th with annual property taxes 5:53 of 5:55 $4,800 what will be the seller's portion 5:58 of the property taxes is if the closing 6:00 date belongs to the seller consider a 6:04 365 day calendar in this property we see 6:08 that it is a total amount of taxes for 6:11 the year of 6:12 $4,800 Step One is to find the daily 6:15 rate so it says to use 365 day calendar 6:20 so now I'm going to divide 6:25 4,800 by 6:27 365 days that's going to equal 6:31 $13 and you have to round to four 6:35 decimal places so since this says 1 6:40 1568 I'm going to round it up to 6:45 $13 and then 6:49 157 step two is now to find the total 6:53 amount of days the seller owns the 6:55 property since the closing is scheduled 6:58 for June 15 7:00 and it belongs to the 7:03 seller I'm going to start counting from 7:07 January so January February March April 7:13 then May and 7:16 June January has 31 days February has 28 7:21 March has 31 April has 30 May has 31 and 7:27 then June since it belongs to the seller 7:29 we'll have 15 days now we're going to 7:33 add up all of those days and we get a 7:37 total of 166 7:40 days so now all we have to do is 7:45 multiply step one's total by the total 7:49 amount of days so 7:54 13157 * 7:57 166 equal 8:05 $2,183 and then it a 01 So my answer is 8:12 B number two Tom sold his property on 8:15 August 1st with annual property taxes of 8:20 $3,600 the closing date belongs to the 8:22 buyer using a 8:24 365-day calendar what will be the sell's 8:28 responsibility of the property taxes in 8:31 this example the property taxes for the 8:33 year are 8:35 $3,600 we are also to use 8:38 365-day calendar we have a closing date 8:42 set for August 1st and it belongs to the 8:48 buyer so Step One is I'm going to find 8:52 the total daily rate I do that by 8:55 dividing $33,600 8:59 by 9:01 365 days that's going to give me 9:07 9863 9:09 01 so we can safely say it just is 9:17 9863 now we find how many days the 9:20 seller owns the property so we have 9:23 January February March April May June J 9:30 July and August since the closing is on 9:33 August 1st and it belongs to the buyer 9:35 August gets zero days so now we just 9:39 fill in the rest of the days January has 9:42 31 February has 28 March has 31 April 9:48 has 30 May has 31 June has 30 July has 9:54 31 we add up all these days and that 9:58 equals 200 112 total 10:02 days now all we have to do is multiply 10:05 this amount by this amount so when you 10:09 multiply 10:11 9.86 3 by 212 days you get a total of 10:19 $2,090 10:21 956 so since this number is five or 10:24 greater we're going to raise this one 10:27 leaving it a total of 10:33 $2,996 as my final answer so the answer 10:37 to number 10:38 two is 10:41 C now let's work out some problems using Problems 10:44 the 360-day pration method for annual 10:51 payments number three Linda sold her 10:55 property on May 1st with annual property 10:58 taxes of 11:00 $6,000 what will be the seller's portion 11:03 of the property taxes if the closing 11:05 date belongs to the seller consider a 11:09 360-day calendar in this example I see 11:12 the closing date is set for May 1st we 11:15 have property taxes for the year of 11:18 $6,000 we're to use a 360-day calendar 11:23 and the closing date belongs to the 11:26 seller so step one is to to find the 11:30 price per day so I will take 11:35 $6,000 and divide it by 11:38 360 days in the 11:40 calendar that 11:42 equals 11:44 16.6 6 6 6 and then 7 remember to use 11:50 four decimal places so I rounded to five 11:53 to then get 11:56 16. 11:58 6666 12:01 7even now I have to find how many days 12:03 the seller own the property for that 12:05 year so we start January February March 12:12 April and May since it's telling me to 12:15 use a 360-day calendar I'm going to use 12:18 30 days for each month except for May so 12:22 January has 30 February has 30 March has 12:28 30 April has 30 and may has one because 12:33 the seller owns the day of closing so 12:37 now we have to add these up and that 12:40 equals 12:41 121 12:44 days now we just multiply step one by 12:47 step two to get our final answer so 12:52 16.6 12:54 667 * 12:57 121 equal 13:01 $216 and then 13:03 670 so it ends up at 13:10 $2,667 that the seller needs to pay at 13:14 closing so the answer is 13:18 D number four Ryan sold his property on 13:22 April 15th with annual property taxes of 13:27 $5,400 what will be the seller portion 13:29 of the property taxes if the closing 13:32 date is pro-rated and it belongs to the 13:35 buyer consider a 13:37 360-day calendar in this example we're 13:41 given property taxes of 13:44 $5,400 and we have a 360-day calendar 13:49 closing day is April 15th and the 13:53 closing day belongs to the buyer step 13:57 one is always to find how much is the 13:59 daily rate so I'm going to divide 14:04 $5,400 by 360 days that equals 14:09 $15 per day now all we have to do is 14:12 find out how many days the seller owns 14:14 the property so if the day of closing is 14:17 April 15th I know that 14:19 January February March and April is all 14:24 we have to count since it's 360-day 14:27 calendar each each month is given 30 14:32 days except for April because we're 14:35 closing on April 15th but since it 14:37 belongs to the buyer we're only going to 14:41 take 14 of those days add of all those 14:44 days and we get a total of 14:48 104 14:50 days now we just multiply step one total 14:54 by step two total so 14:58 $115 time 104 days equal 15:05 $1,560 so the answer to this one is 15:11 B in this section we'll work out some 15:14 problems using the 365 day pration 15:17 method for monthly amounts to be 15:22 prated number five the monthly HOA fee 15:27 for a property is 3 $50 if a seller 15:31 closed on November 12th how much will be 15:34 their portion of the HOA fee for that 15:36 month assume a 365 day calendar here the 15:41 monthly HOA is 15:43 $350 we are scheduled to close on 15:45 November 12th and we're given a 365 day 15:51 calendar in this question since we're 15:53 not given who the closing date belongs 15:55 to you are to automatically assume that 15:58 the Clos closing date belongs to the 16:00 seller so the first thing we have to do 16:03 is find out the total daily amount so 16:07 we're going to take the monthly HOA fee 16:09 of 16:11 $350 and we're going to divide it by 16:13 however many days November has since 16:17 November has 30 days we're going to 16:20 divide by 16:21 30 that equals 16:25 11.66 66 and then repeating six so that 16:30 means we're going to use 16:33 11. 16:37 6667 now we find out how many days the 16:39 seller owns the property for the month 16:42 of November here since it does not 16:44 belong to the buyer we're going to 16:46 include 12 days so since it's just in 16:50 November it is a total of 12 16:54 days now step three is to multiply so 17:00 11.66 17:01 67 * 12 = 17:07 $40 17:09 and0 even So my answer to this one is 17:17 a number six Emma sold her condo where 17:21 the tenant pays a monthly rent of 17:25 $1,200 the closing day is on May 20th 17:28 and the buyer is responsible for closing 17:31 day how much will Emma receive as her 17:33 share of the rent for the month of May 17:36 in this example we see that the amount 17:38 of rent to be prated is 17:40 1,200 we see that the closing day is 17:43 scheduled for May 20th and the buyer is 17:47 responsible for day of closing here it 17:50 is not given the calendar days to use so 17:54 we must assume that 365 day calendar is 17:58 the one we're going to use so in a 365 18:01 day calendar since May has 31 days 18:05 that's what I'm going to use for step 18:07 one remember step one is to find the 18:09 daily total so I'm going to divide 18:14 $1,200 by 31 which is the amount of days 18:18 May has so 18:21 $1,200 divided by 31 = 38.7 18:30 967 so we're going to use 18:35 38.7 18:38 97 now we have to find out how many days 18:41 Emma owned the property in the month of 18:44 May since it's May 20th the day of 18:48 closing and the buyer is responsible for 18:51 closing day that means she only owned 18:53 the property 19 18:55 days so now we just multiply step one 1 18:59 total by step two total and we get 19:10 387973 19:11 and 19:13 484 so since this is five or less it 19:17 just stays at 19:21 $735 19:23 48 So my answer to this one is C 19:30 and in this section we'll work out some 19:32 problems using the 360-day pration 19:35 method for a monthly amounts to be 19:41 prated number seven the monthly HOA fee 19:45 for a property is 19:47 $250 if the seller closed on the 19:50 property on February 15th how much will 19:53 be their portion of the HOA fee for that 19:56 month if the seller owns the day of 19:58 closing 19:59 assume a 360 day 20:01 calendar here I see that the monthly HOA 20:05 fee is 20:06 $250 they are set to close on February 20:10 15 and the seller owns the day of 20:15 closing we're also to use 360 days so 20:19 step one is to find the daily rate so 20:22 I'm going to take the HOA fee of 20:25 $250 and divide it by 30 because we're 20:29 using the 360 day calendar it does not 20:33 matter that February only has 28 days 20:37 remember when using a 360-day calendar 20:41 every month has 30 days now let's divide 20:45 250 by 30 that equals 20:51 8.33 33 repeating okay so we could just 20:55 leave it as 8.33 333 20:59 now we're going to find out how many 21:00 days the seller owned the property in 21:03 February so for February if the closing 21:08 date is set for February 15th and the 21:11 seller owns the day of closing that's 21:15 going to equal a total of 15 days in 21:18 February so now all we do is multiply 21:25 83333 by 15 and we get a total of 21:33 12499 and nine it keeps repeating nine 21:36 well so round it up and that's going to 21:40 equal 21:42 $125 21:44 even so the answer to this one is 21:51 a number eight the monthly HOA fee for a 21:56 property is 21:57 $300 if a buyer closed on April 20th and 22:00 is responsible for the day of closing 22:03 how much will the seller's portion of 22:04 the HOA fee amount to for that month 22:08 assume a 360-day 22:11 calendar for this question the HOA fee 22:15 is 22:16 $300 they're closing on April 22:19 20th buyer is responsible for closing 22:23 date and we're using 360 days so we're 22:28 going to take $300 of the HOA fee and 22:34 divide it by 30 even though April has 30 22:37 days in it already since given the 22:40 360-day calendar we remember to use 30 22:44 days for every month now when we divide 22:48 30 into 300 we get 22:53 $10 that is going to cost $10 per day 22:57 now we're going to have to find out how 22:58 many days in April the seller owned the 23:01 property so if the buyer is responsible 23:05 for day of closing and they're closing 23:07 on April 20th that means it is 19 days 23:13 only now to find the answer is just 10 * 23:18 19 and that's going to equal 23:23 $90 So my answer is B 23:30 and there you have it now you should be 23:32 able to solve these pration questions 23:35 like a pro in this video we explored the 23:38 concept of pration in real estate 23:41 transactions covering annual taxes 23:44
