Settlement Costs in Cost-Seg Basis (Treas. Reg. §1.263)

Which closing-statement line items capitalize into depreciable basis, which expense immediately, and how the calculator handles the settlement_costs field.

Settlement Costs in Cost-Seg Basis (Treas. Reg. §1.263)

This tutorial covers a single mechanic: which closing-statement line items capitalize into depreciable basis under Treas. Reg. §1.263(a)-2 and §1.263(a)-4, and how the calculator's settlement_costs field rolls those dollars into the cost-seg allocation. Property owners often leave money on the table by treating capitalizable acquisition costs as current-year expenses — or by treating financing costs as capital, which they generally are not.

What §1.263(a)-2 actually says

The regulations require a taxpayer to capitalize amounts paid to acquire or produce a unit of real or personal property, and to capitalize amounts paid to facilitate the acquisition. Treas. Reg. §1.263(a)-2(f)(2)(ii) lists the categories that are inherently facilitative — those amounts always capitalize regardless of the timing-or-substance test. The list, paraphrased:

• Transfer taxes (state and local), recording fees, and registration fees.
• Title-related fees: title examination, title insurance premium (owner's policy), title report.
• Architectural, engineering, environmental, and inspection services that relate to the acquisition.
• Application fees, bidding costs, broker commissions on the buyer side.
• Sales tax on the acquisition.
• Appraisal fees commissioned for the purchase.

The regulation distinguishes these from financing costs, which are governed separately by Treas. Reg. §1.263(a)-4(d) and §1.446-5. Loan origination fees, points, and lender title insurance are debt-issuance costs that amortize over the loan term, not basis. Mortgage prepaid interest is a separate timing rule under IRC §461(g). The settlement statement mixes these line items together; sorting them is a CPA's job, but the rough heuristic is: title-and-deed-related fees capitalize into basis; loan-and-interest fees do not.

How the calculator uses settlement_costs

The questionnaire's settlement_costs field accepts a single integer — the property owner's total of capitalizable acquisition costs from the closing statement. The engine adds it to the depreciable basis branch in _compute_basis:

``python if result.depreciable_basis > 0 and inp.settlement_costs > 0: result.depreciable_basis += inp.settlement_costs ``

The added amount flows through the same allocation percentages as the rest of basis — 5-year, 7-year, 15-year, and the 27.5-year building bucket. If the user enters $8,000 of settlement costs on a residential rental with 10% / 0.5% / 7% base allocation, $800 of that $8,000 becomes 5-year personal property, $560 becomes 15-year land improvements, and the remainder rides the building S/L schedule.

This is a pragmatic simplification. A formal engineering study would assign each capitalized acquisition cost to the asset it relates to — title insurance and recording fees attach to the building shell (39-year or 27.5-year), but a pre-purchase phase-1 environmental assessment might more sensibly attach to land. For a screening calculator the proportional split tracks the headline number closely enough; the formal allocation is what an engineering deliverable produces.

Worked example — $8,000 of settlement costs

A property owner buys a long-term rental in March 2026 for $620,000 with $124,000 allocated to land, leaving $496,000 of base improvement basis. The closing statement shows the following capitalizable items:

• Owner's title insurance: $2,800
• Recording fees, transfer tax, deed prep: $1,400
• Buyer's agent commission contribution: $2,500
• Pre-purchase inspection: $700
• Appraisal: $600

Total settlement_costs = $8,000. New depreciable basis: $496,000 + $8,000 = $504,000.

At base LTR percentages (10% / 0.5% / 7%):

• 5-year: $504,000 × 10% = $50,400
• 7-year: $504,000 × 0.5% = $2,520
• 15-year: $504,000 × 7% = $35,280
• 27.5-year building: $504,000 × 82.5% = $415,800

Without entering settlement costs, the same percentages on $496,000 produce $49,600 / $2,480 / $34,720 — roughly $1,400 less in accelerable basis. At 100% bonus and a 32% bracket, that's about $450 less in year-1 federal tax effect. Not transformative on a single transaction; meaningful across a portfolio.

What does not go in settlement_costs

• Loan origination fees, points, lender title insurance — these are debt-issuance costs, amortized over the loan term under §1.446-5.
• Prepaid interest — current-year deduction subject to §461(g) timing rules.
• Property tax prorations — generally allocated between buyer and seller as current-year deductions, not basis.
• Insurance escrow funding — not a basis item.
• Utility transfer fees, HOA dues — current-year operating expenses.

The questionnaire's input help text reflects this. A property owner who is unsure whether a particular line item belongs in settlement_costs is best served by asking their CPA — or omitting the line item entirely; the screening number tolerates the omission.
