Usually, when the office serves that contract. Treasury regulation 26 CFR 1.460-5 requires contractors using the percentage-of-completion method to allocate the costs that directly benefit, or are incurred because of, a long-term contract, and lists rent of equipment or facilities among the indirect costs allocated to exempt construction contracts (ecfr.gov, 26 CFR 1.460-5(b) and (d), checked October 24, 2026).
Confirm the method with your CPA. JOLT delivers each office to one job address at published rates; which contract absorbs the cost, under which accounting method and in which period, is a decision for your books.
What do the tax regulations say about rent on a construction contract?
For contracts reported under the percentage-of-completion method, 26 CFR 1.460-5(b)(1) requires a contractor to allocate to each contract all direct costs and certain indirect costs properly allocable to it. The regulation describes those as the costs that directly benefit the contract or are incurred because the contract is being performed, and it points to the cost rules in 26 CFR 1.263A-1(e).
That second regulation names rent specifically. Under 1.263A-1(e)(3)(ii)(K), rent includes the cost of renting or leasing equipment, facilities or land (ecfr.gov, 26 CFR 1.263A-1(e)(3)(ii)(K), checked October 24, 2026). A rented site office used by a contract's crews falls within that description.
Exempt construction contracts follow a separate paragraph. Under 1.460-5(d)(2)(i)(D), rent of equipment or facilities is among the indirect costs that must be allocated to an exempt construction contract reported using the completed-contract method.
None of this sets a dollar amount or a percentage. The regulations tell you that rent belongs in the contract's costs under these methods; the allocation itself comes from your records.
Which contracts count as exempt construction contracts?
Under 26 CFR 1.460-3(b), an exempt construction contract is one the contractor estimates will be completed within two years of the contract commencement date, performed by a contractor that meets the gross receipts test in section 448(c) (ecfr.gov, 26 CFR 1.460-3, checked October 24, 2026). Home construction contracts are also exempt under the same paragraph.
Exempt contracts can be reported under methods other than percentage of completion, such as the completed-contract method. The method changes when contract costs reach the return, and with it when the office rent is recognized.
Your CPA knows which method each contract uses. Ask before the first invoice is coded, because a site office that runs for a year straddles at least one year end.
Does office rent move a contract's percentage of completion?
Not under the simplified cost-to-cost method. Under 1.460-5(c), a contractor that elects that method computes the completion factor using only direct material costs, direct labor costs and depreciation, amortization and cost recovery allowances on equipment and facilities directly used to construct the subject matter of the contract.
Rent is not one of those three categories. Office rent can still be a contract cost to allocate under paragraph (b) while staying out of the completion-factor arithmetic under the simplified method.
The difference shows up when the office is owned instead. Depreciation on equipment directly used on the contract is one of the three categories, so an owned office raises a question the rented office does not. The Section 179 answer covers what owning the office means for depreciation.
Contractors who do not elect the simplified method use the general cost-to-cost rules, and their CPA decides how rent enters the calculation.
How do you code an office that serves more than one contract?
Pick an allocation basis and use it consistently. Possible bases are the share of crew time, the share of crews or the share of labor hours each contract puts in the office during the month. The 1.263A-1 rules allow reasonable allocation methods and describe burden rates as one option, including a separate rate for rent.
Write the basis down before the first invoice arrives. A one-line rule in the job-cost setup, such as office rent split by labor hours per contract per month, is easier to defend than a split decided after the fact.
When a single office serves one prime contract and its change orders, the allocation is usually simple. When a general contractor runs several owners' work from one yard, the coding decision matters more and should be set by the controller.
Which JOLT charges belong on the job?
A Base 20 ft office rents for $795/mo on JOLT's published prices. Recurring lines can add a 12% damage waiver, a 5% environmental fee and any JOLT Upgrades you keep, and rent rises 5% on each anniversary of delivery.
One-time lines are delivery and pickup, charged per unit for each trip. In Colorado, Wyoming, Utah, Idaho and Montana they follow the published delivery rates; elsewhere in the lower 48 they come from a written project quote. Applicable sales tax is added for the job address.
All of those lines arise because the office sits on the job, so your CPA will usually want them coded to the same contract as the rent. The classification of each line within the contract's costs remains their call.
How do upgrades and add-ons fit the job file?
JOLT Upgrades are billed monthly on the same invoice as the office, and their hardware remains JOLT property. The POWER solar kit at $399/mo, the WATCH camera at $129/mo and the CONNECT Starlink kit at $259/mo each run with the office they serve.
Because they exist only for the site, code them to the same contract as the office rent unless your CPA sets a different rule. A camera watching a shared yard that serves several jobs is the exception that needs an allocation basis of its own.
The JOLT Pack bundles those three at $699/mo, which keeps one recurring line per office instead of three. That can simplify coding, but the allocation question is the same whichever way the upgrades are billed.
Upgrades added mid-project start billing from the month they are installed. Note the start date on the job file so the cost lines up with the period the upgrade served.
Should a schedule extension carry the extra rent?
Schedule slips are where office rent most often drifts from the budget. When the owner extends the work, the months of office rent beyond the original plan are a cost of the extension, and the change order is the place to price them.
Price those months from the current invoice, not the original quote. Rent rises 5% on each anniversary of delivery, so a job that crosses an anniversary carries a higher monthly figure in its later months.
The same extension may change the books. If the office was recorded as a short-term lease, a longer expected stay can trigger the reassessment covered in the ASC 842 answer, so the controller should hear about the extension in the same week as the project manager.
How do you price the office line in a bid?
Estimate the office the way it will be billed. Multiply the monthly rent by the months the office will be on site, then add delivery and pickup for each unit, the protection option and the environmental fee. A Base 20 ft office over 12 months is $9,540 in rent before those lines.
Check the minimum term before you shorten the estimate. Offices carry three months in Colorado and 12 months in every other state, and rent is due for the full minimum even if the job ends sooner.
Add a line for the increase on long jobs. Rent rises on each anniversary of delivery, so a bid for a 30-month project should not price every month at the first-year rate.
Upgrades and sales tax round out the line. Price each upgrade you expect to keep, and carry sales tax at the rate for the job address. The pricing page lists every figure in one place, and the totals become the budget you code invoices against.
Can you bill the office to the owner?
Whether the owner pays for the office is a contract question, not a tax one. Some construction contracts list a site office among general conditions; others treat it as part of the contractor's overhead. Read the general conditions and the payment terms before you assume reimbursement.
Federal work has a written standard. FAR 31.205-36 allows rental costs under operating leases to the extent the rates are reasonable at the time of the lease decision, considering rental costs of comparable property, market conditions in the area, the type, life expectancy, condition and value of the property, alternatives available and other provisions of the agreement (acquisition.gov, FAR 31.205-36, checked October 24, 2026).
A published rate helps with that record. Save the rate you were quoted on the day you ordered, alongside any competing quotes, so the reasonableness file shows what the market looked like at the lease decision. Public-sector buyers can start from the municipal and government page.
What happens to rent after the work is done?
Rent does not stop when the last crew leaves. Under the Rental Agreement Terms, rent is due for the full minimum term, and after that the rental runs month to month until 15 days' written pickup notice and retrieval.
Rent that runs past the end of the work is still paid, but it may not belong to the contract the same way. Your CPA decides where those trailing months go, and a project manager can keep them short by sending pickup notice before closeout rather than after.
The answer on ending a rental explains the notice and pickup sequence. Put the notice date on the closeout checklist so it is not left until the office is the last thing on site.
Does the size of the office change the coding?
No. A 40 ft office with bathroom rents for $1,595/mo and a Base 20 ft office for $795/mo; both are rent under the regulation's description, and both are allocated by the same basis.
Size does change the trips. A 40 ft unit ships on a partner carrier and carries its own delivery figure, so check the delivery and pickup lines for a 40 ft office against the published delivery rates or the project quote before coding them.
When should the coding decision be made?
Before the office arrives. The first invoice comes with delivery, and JOLT bills monthly in advance, so the first month's rent and the delivery fee land together on day one of the job.
Set the job code, the allocation basis and the person who approves the invoice when you place the order. A rental that starts with a clean code stays clean; one that starts in a suspense account tends to stay there until year end.
Is the protection option part of the job cost?
The damage waiver is a 12% charge on the rental, and the alternative is a security deposit with a certificate of insurance. Either choice exists because the office is on the site, so it belongs in the same file as the rent.
The choice affects the coding more than the total. A waiver shows up on each invoice and codes with the rent; the insurance route puts the cost on your own policy, which your CPA may already allocate across jobs in a different way.
What records support the allocation?
Keep each invoice coded to its contract, the delivery and pickup dates, and the allocation basis you chose. Add the job address the office was delivered to, since applicable sales tax follows that address.
For federal work, keep the reasonableness file with the order. For private work, keep the general conditions that decide whether the owner reimburses the office.
The rent deduction answer covers the general IRS rule on rent, and the ASC 842 answer covers how the lease appears in financial statements. For a quote coded to a new job, use the contact form with the job address and expected duration.
Questions contractors ask
Is jobsite office rent a direct or indirect contract cost?
The Treasury regulation on exempt construction contracts lists rent of equipment or facilities among indirect costs, and your CPA decides how your method treats it.
Does office rent count toward percentage of completion?
Not under the simplified cost-to-cost method, which builds the completion factor from direct materials, direct labor and depreciation on equipment and facilities directly used on the contract.
What is an exempt construction contract?
Under 26 CFR 1.460-3(b), it is a contract expected to be completed within two years by a contractor that meets the gross receipts test in section 448(c).
Can I bill the office rental to the project owner?
That depends on your contract with the owner, which decides whether general conditions such as a site office are reimbursed and how they are documented.
Is office rent allowable on a federal contract?
FAR 31.205-36 allows rental costs under operating leases to the extent the rates are reasonable at the time of the lease decision.
How do I split one office between two contracts?
Use an allocation method your CPA accepts, such as the share of time or crews each contract puts in the office, and apply it the same way each month.
What happens to rent after the job is finished?
Rent continues until the office is retrieved after written pickup notice, so give that notice early enough that rent stops close to the end of the work.
Is a JOLT office tied to one job address?
Each order names the delivery address and the Rental Agreement Terms require written consent to move the office, so one address per unit works as a coding key.
