Tax deductions for American self-storage owners and IRS Form 4562

What to take away

Which return carries the depreciation

A facility you actively rent, maintain and manage is a trade or business, not a passive investment. Ordinary income and expenses go on Schedule C for a sole proprietor, Form 1065 for a partnership, Form 1120-S for an S corporation, or Form 1120 for a C corporation.

Depreciation goes on IRS Form 4562, filed with that return. The form reports the depreciation and amortization deduction, any section 179 election, and listed property such as vehicles.

A single-member LLC that has not elected corporate treatment is a disregarded entity. The owner reports everything on Schedule C and Form 4562 as if the LLC did not exist. That is the usual structure for a first facility.

State treatment can differ. Texas levies no personal income tax but imposes a franchise tax on many entities. California, New York and Illinois tax rental and business income, and each applies its own conformity rules to federal depreciation. Ask your CPA whether your state follows federal MACRS or requires an adjustment.

Clean monthly books turn the Form 4562 entries into a copy-and-paste job instead of a March reconstruction. The same discipline that supports your profit margins and break-even analysis supports the return.

MACRS recovery periods for a storage facility

MACRS assigns every asset a class life. Publication 946 is the controlling document when you are unsure whether a component is 5-year, 15-year or 39-year property.

The 39-year life surprises new owners. It deducts roughly 2.56 percent of building basis a year. A $1.2 million building generates about $30,700 of annual depreciation, not the six-figure write-off people imagine.

Land is the reason the number is smaller than the purchase price. A $1.5 million acquisition on a $400,000 lot leaves $1.1 million to depreciate.

Cost segregation changes the math. An engineer reclassifies components that qualify as 5-year or 15-year property: the gate, the keypad system, interior partitions, dedicated electrical, signage and site work. Moving $300,000 from a 39-year schedule to a 15-year schedule accelerates the deduction sharply in the early years.

The study costs money and makes sense mainly on larger acquisitions or properties you plan to hold. Bonus depreciation has narrowed since 2023. Qualified improvement property, generally interior work on a nonresidential building, is 15-year property eligible for bonus treatment, and the available percentage depends on the placed-in-service year. Confirm the current rate before you rely on a number.

Line by line through Form 4562

The Instructions for Form 4562 divide the form into six parts.

A worked example

An owner buys an Arizona facility for $1.4 million, with $350,000 allocated to land. Building basis is $1,050,000 on the 39-year schedule. A cost segregation study moves $220,000 into 15-year land improvements and $90,000 into 5-year equipment.

The owner elects section 179 on the $90,000 of equipment and claims bonus on part of the 15-year property. The remaining building basis stays on the 39-year straight-line schedule. The accountant enters the building on line 17i, the land improvements on line 17j, and the section 179 amount in Part I.

One trap: the form asks separately for the business-use percentage of listed property and for total cost before any section 179 election. Mixing those fields turns a routine filing into a correspondence audit.

In the first year, the line between a start-up cost amortized over 15 years and an ordinary expense deducted immediately is decided on that return. Owners weighing an acquisition should read startup costs and funding options before the closing date, and check markets for a self-storage business before choosing one.

Entity structure and the deduction

Entity structure does not change the MACRS recovery period. It changes who reports the depreciation, which return it appears on, and whether self-employment tax applies to rental income.

Rental income is generally not self-employment income, but the IRS looks at whether the owner provides substantial services. Signing tenants, cleaning units and handling move-outs looks like a business.

An S corporation can pay the owner a reasonable salary and treat the rest as a distribution, which reduces self-employment tax. It also requires payroll, filings and a defensible salary figure.

Liability drives structure as much as tax does. Most operators with more than one property hold each in its own entity, which separates facility obligations from personal assets. The trade-off is more returns, more state fees and more accounting cost.

Run the numbers with a CPA who has storage clients. The right answer for a single 200-unit facility in Georgia is usually wrong for a four-property portfolio in Texas and Florida.

Why 27.5 years does not apply

Publication 527 covers residential rental property, which depreciates over 27.5 years. A residential rental is a building where at least 80 percent of gross rental income comes from dwelling units.

A storage facility fails that test. Units are not dwelling units, nobody lives there, and the income is from storage. The property is nonresidential real property at 39 years.

Some operators try residential treatment for a converted apartment building that now holds storage. The argument fails on the 80 percent test and on the nature of the units. Claiming 27.5 years overstates the annual deduction and produces a correction plus interest on audit.

A resident manager's apartment is the one exception worth tracking. If it is genuinely rented as a dwelling, depreciate it separately as residential rental property on its own asset line.

Owners who also hold duplexes or rentals should keep those schedules apart from the storage building. Mixing them invites an allocation error that is hard to unwind years later.

Repairs, vehicles and operating costs

Depreciation is the largest line, not the only one. Ordinary and necessary business expenses are deductible in the year paid:

Credit card processing fees, on-site wages and third-party management fees belong there too. The guide to business expense resources is the starting point for what qualifies.

Repairs versus improvements is the most audited line. Painting a unit door is a repair. Replacing every door with a heavier gauge door is an improvement and must be capitalized.

A new roof that restores prior condition is generally a repair; a roof that upgrades the structure or extends its life is capitalized.

Write the reasoning down when you make the call, not two years later.

Vehicle costs are deductible at the standard mileage rate or by actual expenses, never both. Log date, destination, business purpose and miles. A truck for facility runs and supply pickups qualifies. The commute from home to the office does not.

A home office deduction requires space used regularly and exclusively for the business. For most storage owners that is a desk and a filing cabinet, and the deduction is modest against the recordkeeping burden.

Marketing, signage, tenant screening and business subscriptions are deductible. Track them in the same ledger as operating costs so the categories stay clean at year end.

Records that answer an audit

The IRS can examine returns for three years, or six if gross income is understated by more than 25 percent. Your file should answer every Form 4562 question without a call to the seller.

Keep the schedule current every year. A spreadsheet that starts at acquisition and adds each capitalized item as it is placed in service is enough, as long as it shows accumulated depreciation and net book value. That is what a buyer asks for in due diligence and what an examiner reconciles against the returns.

Owners who track KPIs owners should track monthly already hold the occupancy and revenue records behind the income side of the return. The depreciation schedule supports the other side. A pricing and profit guide belongs in the same folder as the subscription receipts.

Common questions

Does a self-storage facility depreciate over 39 years or 27.5 years?

39 years. Storage units are not dwelling units, so the property is nonresidential real property under MACRS. The 27.5-year life applies to residential rentals, which fail here on the 80 percent dwelling-unit test.

Can I depreciate the land under my facility?

No. Land is never depreciable. The purchase price must be allocated between land and improvements, and only the improvements go on the depreciation schedule. Your closing statement or a qualified appraiser supplies that split.

What does a cost segregation study do for a storage facility?

It reclassifies components such as paving, fencing, security systems and site work into 5-year and 15-year property. That accelerates deductions in the early years instead of spreading them across 39. It makes sense mainly on larger acquisitions or long holds.

Does an LLC change my depreciation deduction?

Not the amount. A single-member LLC is disregarded and reports on Schedule C with Form 4562. A multi-member LLC files Form 1065 and passes depreciation to partners on Schedule K-1. Ask a CPA which structure fits your portfolio.
