The IRS treats most storage buildings as nonresidential real property, depreciated over 39 years with the mid-month convention, and does not allow depreciation on land. Beyond that, your tax result depends on how you hold the property, what you spent and what your state taxes, so take the questions below to a CPA who knows real estate.
This is general information, not tax advice. Tax rules change every year. Talk to your CPA before you buy, build, sell or file.
The tax picture in one table
| Topic | The basic idea | Ask your CPA |
|---|---|---|
| Rental income | Rent is income in the year you receive it (cash method) | Cash or accrual? Which form? |
| Operating expenses | Deductible in the year paid, if ordinary and necessary | What counts as a repair vs an improvement? |
| Depreciation | Building cost is deducted over time | What is my basis? Land split? |
| Cost segregation | Faster write-off for some components | Is a study worth the fee for my facility? |
| Interest | Loan interest is deductible; principal is not | Any limits that apply to me? |
| Sales tax | Depends on state | Do I charge it on rent, locks, boxes? |
| Sale | Gain, depreciation recapture, possible deferral | How should I plan a sale? |
| Entity | LLC, S corp, partnership | See entity and licensing |
How depreciation works
Depreciation lets you deduct the cost of a building a bit each year, because buildings wear out. It is a tax deduction, not a cash expense, so it lowers taxable income without lowering your cash flow.
Three facts from the IRS:
- Nonresidential real property has a 39-year recovery period under MACRS, per the Form 4562 instructions.
- The mid-month convention applies. Property placed in service during a month is treated as placed in service in the middle of that month, so the first and last years are partial.
- Land is not depreciable. Publication 946 says you cannot depreciate land because it does not wear out, become obsolete or get used up.
Worked example (illustrative)
Say you buy a facility for $1,500,000. Your CPA, using an appraisal or the county tax roll, allocates $300,000 to land and $1,200,000 to buildings. The building basis is $1,200,000.
- Straight line over 39 years: $1,200,000 / 39 is about $30,769 per year.
- First year uses the mid-month convention. If the facility is placed in service in the middle of June, the first-year deduction covers about 6.5 months, or roughly 6.5/12 of a full year: $30,769 times 6.5 / 12 is about $16,667. Your CPA will use the IRS tables, which can differ slightly.
On $180,000 of NOI and say $60,000 of interest, a $30,769 deduction cuts taxable income by that amount before other items. At a hypothetical combined tax rate of 25 percent, that is about $7,692 in tax. Your rate and result differ; the point is the size of the effect.
Which parts of the property depreciate faster
Not everything at a storage facility is "building." Some assets have shorter lives under the tax code, which is why people talk about cost segregation. Ask about:
- Paving, fencing, lighting and signs (often treated as land improvements)
- Gate systems, cameras and kiosks
- Office furniture, computers and tools
- Roll-up doors and partitions (your CPA decides how to classify them)
Section 179 and special depreciation
The Form 4562 instructions describe a Section 179 deduction (the 2025 limit is $2,500,000, reduced when total qualifying purchases exceed $4,000,000) and a special (bonus) depreciation allowance of 100 percent for qualified property acquired after January 19, 2025, with an election to take 40 percent instead in the first year. Rules differ by year and by property type, and Congress changes them. Do not plan from this paragraph. Ask your CPA what applies to equipment you buy this year and next.
Cost segregation
A cost segregation study is done by an engineer or specialist. It splits your purchase or construction cost into components with shorter lives, so more of the cost is deducted sooner. It can help larger or newer properties and may not pay off for a small, older facility. Fees are real, so ask for a written estimate of the benefit before you hire anyone. Note that selling later can trigger recapture, which your CPA can explain.
Repairs versus improvements
The IRS draws a line between work that keeps the property running (a repair, usually deducted now) and work that improves it or extends its life (an improvement, usually depreciated). The rule has details, and storage examples are not always obvious.
| Likely repair | Likely improvement |
|---|---|
| Patching a roof leak | Replacing the whole roof |
| Replacing a broken door spring | Replacing all doors in a building |
| Filling potholes | Repaving the entire lot |
| Repainting | Adding a new building or units |
Keep invoices, photos and notes on why you did the work. Your bookkeeping should tag each as repair or capital.
Schedule E or Schedule C
Passive rental income is often reported on Schedule E. If you provide substantial services, such as a staffed office, truck rental and retail, the IRS may see a business and your CPA may use Schedule C, which affects self-employment tax. Which applies to you is a fact-specific question. Ask your CPA early, and ask whether an entity such as an LLC changes anything. Read entity and licensing basics.
Sales tax
States vary. Some tax storage space rent, some tax only retail sales such as locks and boxes, and some tax nothing. Some states exempt self-service storage but tax full-service storage. Check your state department of revenue or ask your CPA. If you collect sales tax, you will need a permit and a filing schedule, and your books need a "sales tax payable" account.
Property tax
Your county assessor values the property, and a sale or new construction can change the assessment. Ask your CPA or a property tax consultant about appeals, and ask your attorney about deadlines. Include the expected tax in any valuation, since taxes can rise after a purchase.
Buying and selling
- Buying: The price allocation between land, buildings and equipment drives your depreciation. Talk to your CPA before closing. See buying an existing facility.
- Selling: Gains and depreciation you took earlier can be taxed differently. Ask about timing, installment sales and exchanges well before you sign. See how to sell a self storage facility.
Year-end checklist
- Rent roll and rent collected tie to bank deposits
- Deposits, prepaid rent and surplus owed separated
- Invoices for repairs and capital items filed and tagged
- Purchase closing statement and appraisal given to CPA
- Depreciation schedule updated
- Sales tax filings current, if you collect it
- Insurance and property tax bills collected
- 1099s filed for contractors, if applicable
Get your reports in order first; it saves your CPA time and your money. Know your NOI too, but remember NOI is not taxable income, because it leaves out interest and depreciation.
Questions to bring to your CPA meeting
Bring a one-page list so the meeting is short and useful:
- Which form and schedule will report this property, and why?
- How should we allocate the purchase price between land, building and equipment?
- Does a cost segregation study make sense at my size and age of building?
- Which of my planned purchases this year qualify for faster depreciation, and which do not?
- What counts as a repair and what counts as an improvement for the work I have planned?
- Do I need to collect or file sales tax?
- How does my entity change my taxes?
- If I plan to sell or refinance in the next few years, what should I do now?
- What records do you need from me, and by when?
What your software can and cannot do for taxes
Storage software tracks rent, fees and balances. It does not decide how those are taxed. What it can do is give you clean totals. A rent roll, a collected-rent report and a delinquency report let your CPA match income to bank deposits. Export your data at year end and keep a copy with your tax file.
Planning ahead
Most tax planning happens before a purchase, a build or a sale, not after. Talk to your CPA when you sign a letter of intent, before you close on construction financing, and again in the fall each year, while there is still time to act on equipment purchases or repairs. Tax rules for depreciation have changed in recent years and may change again, so confirm current rules every year.
This is general information. Your CPA is the right person to apply the tax code to your facility.
