How to Calculate Depreciation on a Rental Property (Made Simple!)

๐Ÿ  If you own a rental property, hereโ€™s some good news: you can deduct a portion of its cost every year on your taxes through something called depreciation.

Even better? You donโ€™t need to be an accountant to figure it outโ€”weโ€™ll walk you through it step by step!

๐Ÿ™‹ What Is Depreciation?

Depreciation is the process of spreading out the cost of your rental property over time. The IRS assumes that buildings wear down (even if they actually go up in value), so they let you deduct part of the cost each year.

This helps reduce your taxable income, meaning you could owe less in taxes.

โญ Important Basics Before You Start

Hereโ€™s what you need to know:

  • ๐Ÿ  Only the building depreciates โ€” not the land.
  • ๐Ÿ“† Residential rental properties are depreciated over 27.5 years.
  • ๐Ÿ“… You start depreciating the property the year itโ€™s placed in service (rented out).
  • โœ… You must own the property and use it to produce rental income.

๐Ÿงฎ How to Calculate Depreciation on a Rental Property

๐Ÿ“Œ Step 1: Determine the Cost Basis of the Property

This is usually the purchase price, plus:

  • Closing costs (like legal fees or title fees)
  • Major improvements (like a new roof or HVAC)

๐Ÿ“Œ Step 2: Separate Land and Building Value

You canโ€™t depreciate landโ€”only the building.
Use the tax assessorโ€™s records or appraisal to split the value.

โš™๏ธ Example:

  • Purchase price: $300,000
  • Assessed value shows: 80% building, 20% land
    โ†’ Building value = $300,000 ร— 80% = $240,000

๐Ÿ“Œ Step 3: Use the 27.5-Year Rule

Now divide the building value by 27.5 years.

Annual Depreciation = Building Value รท 27.5

โœ… $240,000 รท 27.5 = $8,727.27 per year

Thatโ€™s how much you can deduct each year for depreciation!

๐Ÿงพ What About Partial Years?

If you bought the property mid-year, youโ€™ll only depreciate it for part of that year. The IRS uses a “mid-month convention” which assumes you started renting it halfway through the month you placed it in service.

๐Ÿ’ก Donโ€™t worryโ€”you can use IRS Publication 527 or tax software to get the exact monthly amount.

๐Ÿ’ก Bonus Tip: Keep Records!

Hold onto:

  • Purchase documents
  • Appraisals or assessor records
  • Improvements made to the property

This helps support your deduction in case the IRS comes knocking!
