Leasehold Improvements and Tenant Build-Out for Freelancers: Repair vs Improvement, the Small Taxpayer Safe Harbor and QIP (2026 Schedule C Guide)

Published: October 23, 2026 · Reading time: 12 min

TL;DR: When you rent a studio, shop or office, repairs that keep the space in its existing condition go on Schedule C line 21, but improvements you pay for, such as a new partition wall or new electrical, are generally capitalized and recovered on line 13 through Form 4562. Two tools can change the outcome: the small taxpayer safe harbor (Treas. Reg. 1.263(a)-3(h)), which lets you deduct a year's repairs and improvements to one building if the total is at most the lesser of 2% of total lease-term rent or $10,000, and qualified improvement property (QIP), which is 15-year property eligible for 100% bonus depreciation when acquired after January 19, 2025. On a 36-month lease at $1,800 a month the safe harbor cap is only $1,296.

Signing a lease for your first real studio is exciting. Then the contractor's quote arrives: paint, a partition, new outlets, track lighting. Some of that is a current expense. Some of it has to be capitalized. And a few clean rules decide which is which.

This guide covers the tenant's side of that line. For the basic line 21 test, see our Schedule C line 21 guide. For depreciation mechanics, see Schedule C line 13.

Where the Money Goes on Schedule C

A tenant build-out touches three places on Schedule C:

The Schedule C instructions point both ways. For repairs they say to "Deduct the cost of incidental repairs and maintenance that do not add to the property's value or appreciably prolong its life." In the same breath they say "Do not deduct amounts spent to restore or replace property; they must be capitalized." And for depreciation: "You can also depreciate improvements made to leased business property."

Rent itself is covered in our Schedule C line 20 guide. Build-out is the part that guide hands off to depreciation.

Repair or Improvement: The Lessee's Rule

Treas. Reg. 1.263(a)-3(f) is the exclusive rulebook for improvements to leased property, apart from the two safe harbors below. Its core sentence is short: "A taxpayer lessee must capitalize the related amounts" it pays to improve leased property. (There is a carve-out where a construction allowance from the landlord falls under section 110, and another for improvements that are a substitute for rent. Ask your preparer if your landlord paid for part of the work.)

What counts as an improvement comes from paragraph (d). A unit of property is improved if the amounts paid are for:

1. a betterment,
2. a restoration, or
3. an adaptation to a new or different use.

For a lessee of part of a building, the "unit of property" is the portion of the building you lease and its related structural components, which is why a suite, floor or square footage you rent is analysed as its own unit.

What a betterment looks like

Under paragraph (j)(1), an amount is paid for a betterment only if it fixes a pre-existing material defect ("Ameliorates a material condition or defect"), is for "a material addition" including a physical enlargement or extension, or is reasonably expected to "materially increase the productivity, efficiency, strength, quality, or output" of the unit of property.

Applied to a rented studio:

These are typical classifications, not rulings. The facts of each job decide, and a CPA or EA can confirm.

The routine maintenance safe harbor

Paragraph (i) deems recurring upkeep not to be an improvement. For a building it covers recurring activities such as "inspection, cleaning, and testing" and replacing damaged or worn parts with comparable parts, but only if you reasonably expect to perform them "more than once during the 10-year period" beginning when the building structure or system was placed in service by you. It protects upkeep, not a build-out. A new partition is not recurring maintenance.

The Small Taxpayer Safe Harbor: A Cap Tied to Your Rent

Paragraph (h) lets a qualifying taxpayer elect not to apply the capitalization rules to an eligible building if the total paid in the year for "repairs, maintenance, improvements, and similar activities" on that building is no more than the lesser of two numbers: 2 percent of the building's unadjusted basis, or $10,000.

For a tenant, the unadjusted basis is not the building's value. The regulation defines it as "the total amount of (undiscounted) rent paid or expected to be paid by the lessee under the lease for the entire term of the lease, including renewal periods if all the facts and circumstances in existence during the taxable year in which the lease is entered indicate a reasonable expectancy of renewal."

The rules in plain terms:

• Qualifying taxpayer. Average annual gross receipts for the three preceding taxable years of $10,000,000 or less, which describes nearly every freelancer.
• Eligible building property. A leased building or leased portion of a building whose unadjusted basis is $1,000,000 or less. The regulation's own example involves a retail store lessee with a 20-year triple-net lease.
• All or nothing. The test applies to the total spent on the building in the year. If total spending exceeds the cap, the safe harbor does not apply to any of it for that building that year, and you go back to the general rules.
• Counts everything. Amounts expensed under the de minimis safe harbor and amounts covered by the routine maintenance safe harbor count toward the total.
• Annual election. You attach a statement to your timely filed original return (including extensions), titled "Section 1.263(a)-3(h) Safe Harbor Election for Small Taxpayers," with your name, address, taxpayer identification number and a description of each building. The regulation says an election cannot be revoked.

Why the cap is small for most freelancers

A short or modest lease produces a small cap. The 2% test usually binds well before $10,000 does.

The cap reaches $10,000 only when total lease-term rent is $500,000 or more. If renewals are reasonably expected, they count toward the rent total, which can raise the cap, so keep the lease and any renewal terms with your records.

Qualified Improvement Property (QIP): Why Build-Out Depreciates Well

If a build-out must be capitalized, QIP is the best case. Section 168(e)(6) defines it as "any improvement made by the taxpayer to an interior portion of a building which is nonresidential real property if such improvement is placed in service after the date such building was first placed in service."

Three exclusions apply: improvements attributable to "the enlargement of the building," "any elevator or escalator," or "the internal structural framework of the building."

Three consequences follow:

1. It is 15-year property. The statute lists QIP within 15-year property in section 168(e)(3)(E), and section 168(b)(3)(G) puts it on straight-line depreciation.
2. It can qualify for bonus depreciation. Section 168(k) applies to qualified property with a recovery period of 20 years or less. For property acquired after January 19, 2025, the allowance is "an allowance equal to 100 percent of the adjusted basis of the qualified property." You may elect out for a class of property, and the effective-date note says the amendments "shall apply to property acquired after January 19, 2025." If the work was contracted before that date, ask your preparer which acquisition date controls.
3. It is section 179 property if you elect. Section 179(e) lists "any qualified improvement property described in section 168(e)(6)" as qualified real property. For 2026, Rev. Proc. 2025-32 sets the section 179 limit at $2,560,000, reduced dollar for dollar once qualifying purchases exceed $4,090,000. Section 179 is also limited by your business taxable income, which can include more than your Schedule C profit. See Section 179's income limit and our Section 179 guide.

QIP is a narrower label than "everything in the build-out." Exterior work, an addition and structural framework are outside it. Section 179(e)(2) separately lists roofs, HVAC, fire protection and alarm systems, and security systems as qualifying improvements to nonresidential real property, but those items are a different category from QIP and may not be eligible for bonus depreciation. Movable furniture and equipment you bring into the space are usually depreciated as equipment, not as part of the leasehold build-out. Your preparer decides the classification of each invoice line.

The choices between bonus and section 179 are compared in our Section 179 vs bonus depreciation guide and bonus depreciation guide.

Worked Example: A Photographer Builds Out a Rented Studio

A photographer signs a 36-month lease on a 900 square foot studio at $1,800 a month. Her average annual gross receipts are far below $10,000,000. In year one she pays a contractor:

Step 1: Safe harbor test. Total rent is 36 × $1,800 = $64,800. Two percent is $1,296, which is below $10,000, so the cap is $1,296. Total spending of $12,630 exceeds it, so the safe harbor is unavailable for this studio this year.

Step 2: General rules. Repairs are $1,150 + $480 = $1,630 for line 21. Improvements are $6,800 + $4,200 = $11,000, and she asks her preparer to confirm they are QIP: interior, nonstructural and made after the building was first placed in service.

Step 3: Recovery choice. If bonus depreciation applies and she does not elect out, the $11,000 is deducted in year one on line 13. If she elects out or the work does not qualify, the cost is spread over 15 years, about $733 in a full year ($11,000 ÷ 15), with the first and last years set by the depreciation convention.

That total is the three lines added: $21,600 + $1,630 + $11,000 = $34,230. Whether bonus depreciation is a good choice for her depends on her income this year and later years, because a large first-year deduction leaves less depreciation for future years. This example does not estimate a tax saving, which depends on her whole return.

A smaller year. If instead she had spent only $1,200 on a built-in alcove, her total would be at or below the $1,296 cap. She could elect the small taxpayer safe harbor by attaching the required statement, and deduct the $1,200 under the ordinary expense rules rather than capitalizing it.

The De Minimis Safe Harbor Still Applies to Small Items

Separate from building work, the de minimis safe harbor lets you expense items instead of capitalizing them. The IRS states the limit for taxpayers without an applicable financial statement: "up to $2,500 ($500 prior to Jan. 1, 2016) per invoice or item (as substantiated by invoice)." It is an annual election. Our de minimis safe harbor guide covers the statement and the books-and-records requirement.

The safe harbor works for a $900 light fixture bought and installed by you. It does not turn a $6,800 partition invoice into an expense, and it should not be used to slice one job into several smaller invoices. Any amount you expense this way still counts toward the building's total for the small taxpayer safe harbor.

Records to Keep

A tenant who capitalizes a build-out depreciates it for years. Keep:

• The lease, with its term, renewal options and any landlord allowance.
• Itemized contractor invoices that separate repairs from new work.
• Before-and-after photos of the space.
• The date each improvement was placed in service.
• A note of the classification you and your preparer chose for each line.

See how long to keep receipts and our guide to Schedule C recordkeeping by line. Depreciation records outlive the usual three-year window, since the deduction runs across the property's recovery period.

Common Mistakes Tenants Make

1. Putting the whole contractor invoice on line 21. A partition or new wiring is an improvement, even when the invoice is labeled "repairs."
2. Assuming the $10,000 safe harbor cap applies. For a tenant it is 2% of total lease-term rent, which is often a four-figure number or less.
3. Forgetting it is all or nothing. Spending $1 over the cap forfeits the safe harbor for that building that year.
4. Missing the election statement. The small taxpayer safe harbor and the de minimis safe harbor each need an election with a timely filed return.
5. Treating the landlord's allowance as free. If the landlord paid for improvements or gave you a construction allowance, the regulation has special rules, so tell your preparer.
6. Assuming every part of a build-out is QIP. Additions, elevators and structural framework are excluded.
7. Splitting invoices to fit under a threshold. The threshold applies per invoice or item, and artificial splitting invites questions.
8. Ignoring mixed use. If the space is also your home or used for personal purposes, the business share is what counts. See our Schedule C line 20 guide and the guide to subletting studio space if you rent part of the space to others.

How CentSense Helps

CentSense keeps the paper trail for a build-out in one place:

• Scan contractor, hardware and fixture receipts with AI the day you pay, so the vendor, date and total are captured. The free tier includes 10 AI scans a month
• Tag each receipt as a repair or an improvement and add a note of what was done, so your preparer can see the classification
• On the Solo and Team plans, export your categorized expenses as CSV so your preparer can map repairs to line 21 and capitalized work to Form 4562

CentSense tracks and organizes expenses. It does not decide whether work is a repair or an improvement, whether it is qualified improvement property, or whether you should elect a safe harbor. Those are judgment calls for you and your CPA or EA.

Frequently Asked Questions

Can I deduct build-out costs for a studio or shop I rent on Schedule C?

Usually not all at once on line 21. The regulation says a lessee must capitalize amounts it pays to improve leased property, and the Schedule C instructions say you can depreciate improvements made to leased business property. Repairs that keep the space in its existing condition are deductible on line 21, but new walls, built-in wiring and similar work are generally capitalized and recovered on line 13 through Form 4562, sometimes in the first year through bonus depreciation or section 179. Which bucket each invoice falls into depends on the facts, so confirm with a CPA or EA.

What is the difference between a repair and a leasehold improvement?

A repair keeps the space in its ordinarily efficient operating condition, such as repainting existing walls or replacing a cracked tile with a like-for-like one, and goes on line 21. A leasehold improvement is work that is a betterment, a restoration or an adaptation to a new use under Treas. Reg. 1.263(a)-3(d), such as adding a partition wall or a new lighting and electrical system, and it is capitalized and depreciated on line 13. The regulation treats a materially added or enlarged space and a reasonably expected material increase in quality or output as betterments. A routine maintenance safe harbor can keep recurring maintenance on line 21, but it does not cover a new build-out.

What is the small taxpayer safe harbor for a rented studio or office?

It lets a qualifying taxpayer elect to deduct, instead of capitalizing, the total spent on repairs, maintenance and improvements to one building if that total is no more than the lesser of 2 percent of the building's unadjusted basis or $10,000. For a leased space the unadjusted basis is the total undiscounted rent for the lease term, including renewals you reasonably expect. The three-year average of annual gross receipts must be $10,000,000 or less, the leased space's unadjusted basis (total lease-term rent) must be $1,000,000 or less, the election is made by attaching a statement to your timely filed return, and it is all or nothing for that building and year. If total spending exceeds the cap, the safe harbor is unavailable for that building that year.

How much can I spend before the small taxpayer safe harbor stops working for my lease?

It is 2 percent of the total rent over the lease term, capped at $10,000 per building per year. On a 36-month lease at $1,800 a month, total rent is $64,800, so the cap is the lesser of $1,296 and $10,000, which is $1,296. Total spending on repairs, maintenance and improvements to that space counts together, so $12,630 in a year blows through it. The cap is measured against rent for the whole lease term including reasonably expected renewals, so a longer lease raises it, up to the $10,000 limit, as long as total lease-term rent stays at or below $1,000,000 (above that the building is ineligible). The safe harbor also requires the three-year average gross receipts test and a timely election statement.

What is qualified improvement property, and why does it matter to a tenant?

Qualified improvement property (QIP) is an improvement made by the taxpayer to an interior portion of a nonresidential building, placed in service after the building was first placed in service. It excludes enlargement of the building, any elevator or escalator, and the internal structural framework. QIP is 15-year property under section 168(e)(3)(E), so it can qualify for bonus depreciation, which is 100 percent for property acquired after January 19, 2025, and it is also section 179 qualified real property. Exterior work, additions and structural framework changes do not qualify, so ask your preparer how each part of a build-out is classified.

Can I deduct my whole tenant build-out in the first year?

Often yes, but through depreciation rules rather than line 21. Interior nonstructural build-out that is QIP is 15-year property, and bonus depreciation under section 168(k) allows 100 percent of the adjusted basis for qualified property acquired after January 19, 2025, unless you elect out for that class of property. Section 179 is another route, with a 2026 limit of $2,560,000 that is reduced once qualifying purchases exceed $4,090,000, and it is also limited by your business taxable income. Work that is not QIP, for example an addition or structural framework, may not qualify, and work contracted before January 20, 2025 needs a preparer's review of the acquisition date.

Do I have to capitalize a small fix like repainting or replacing a tile in my rented space?

Repainting existing walls or replacing a cracked tile with a like-for-like one is generally a repair that goes on line 21, which the Schedule C instructions describe as incidental repairs and maintenance that do not add to the property's value or appreciably prolong its life. The same instructions say amounts spent to restore or replace property must be capitalized, so a large-scale replacement is different. If you are not sure, the small taxpayer safe harbor can keep a modest year of combined spending on the current-deduction side, subject to its cap and election statement. Costs of finishing a new partition, such as painting the new wall, travel with that improvement.

Does the $2,500 de minimis safe harbor cover part of a build-out?

Only for items or invoices of $2,500 or less, and only if you make the annual election and have no applicable financial statement. The IRS states the limit as $2,500 per invoice or item, and the safe harbor covers amounts paid to acquire or produce tangible property, so a single $6,800 partition invoice would exceed it. Small separate purchases may qualify, but splitting one job across invoices to get under the line is a risk to raise with your preparer. Amounts expensed under the de minimis safe harbor still count toward the building's small taxpayer safe harbor total.
