Cost segregation data for Arlington, VA + Northern Virginia investors
Interquartile range across 50 engine-modeled property scenarios matched to the Arlington, VA + Northern Virginia investor profile. Year-1 savings shown are the federal benefit (37% + 3.8% NIIT). This state does not conform to federal bonus depreciation, so the state share is not accelerated; it recovers over standard MACRS.

May 2026 (reproducible seed: arlington-va_v1_2026-05-17).
Year-1 savings shown are the federal benefit only (37% + 3.8% NIIT). This state does not conform to federal §168(k) bonus depreciation, so the state share is deferred over standard MACRS rather than realized in Year 1; the federal benefit is unaffected. Confirm specifics with your CPA.
Tax law current as of May 2026. Federal: OBBBA restored 100% bonus depreciation under §168(k), permanent for property placed in service on or after January 20, 2025 (property placed in service January 1–19, 2025 remains at 40% under the prior phase-down); 2026+ stays 100%. State conformity varies; verify with your CPA.
If you live in Arlington, Alexandria, Tysons, or anywhere in Northern Virginia, you pay federal 37% + NIIT 3.8% + VA 5.75% = ~46.5% combined — a meaningful step down from DC’s 10.75% top state-equivalent rate. Cost segregation on out-of-state STR converts that bracket into Year-1 cash savings.

Who are Northern Virginia cost segregation investors?
NoVA’s cost-seg buyer pool is distinct from DC proper — heavier defense-contractor and tech-contractor concentration, more dual-income households, lower state tax (VA 5.75% vs DC 10.75%):
- Defense contractors and federal-tech (Booz Allen, Deloitte Federal, Accenture Federal, MITRE, SAIC, Leidos, Raytheon-RTX, Northrop) — $250K–$900K + bonus
- Cleared tech and gov-tech (Palantir, Anduril, AWS GovCloud, Microsoft Federal, Amazon HQ2) — $300K–$1.2M with equity
- BigLaw and regulatory (DC-firm partners and senior counsel who live in NoVA for the lower tax) — $400K–$1.5M+
- Senior consulting + management consulting (McKinsey DC, Bain DC, BCG DC) — $300K–$1M+ with project bonus
The combined marginal-rate stack:
- Federal: 37%
- NIIT: 3.8%
- Virginia: 5.75% (top rate, applies at $17K+ taxable income)
- Combined: ~46.5%
The 5 percentage point gap vs DC residents is exactly why many high-comp NoVA buyers keep an Arlington/Alexandria/Tysons residence rather than DC proper. Over a 10-year hold + 100% bonus depreciation Year-1 deduction window, that gap meaningfully compounds.
Verify with your CPA — combined-rate math depends on filing status, AGI thresholds for NIIT, and the actual VA bracket your income lands in.
Why cost seg pays more if you live in NoVA
A typical $500K–$1.2M out-of-state STR reclassifies 24–32% of basis under permanent 100% bonus depreciation. At the federal rate (37% + 3.8% NIIT; Virginia portion deferred over MACRS), every $1 of accelerated depreciation is worth ~$0.408 federally in Year-1 cash savings.
The NoVA investor has a structural advantage NYC and SF don’t: dual-income households are common, and if one spouse works at home or part-time, that spouse can often qualify for Real Estate Professional Status (REPS — 750+ hours + >50% personal services in real estate). REPS converts ALL rental losses (not just STR) into non-passive, dramatically expanding the cost-seg strategy beyond the STR exception under Reg. §1.469-1T(e)(3)(ii).
Where do NoVA investors buy property?
NoVA investors flow capital to STR markets within a 1-3 hour drive or short flight:
- Outer Banks, NC — Atlantic coastal STR, 5-hour drive market for NoVA.
- 30A / Destin, FL — Florida 0% state tax, premium beachfront, direct IAD/DCA flights.
- Smoky Mountains (Pigeon Forge, Gatlinburg) — Tennessee 0% state tax, cabin STR.
- Charleston, SC — Historic, walkable, strong year-round ADR.
- Asheville, NC — Blue Ridge mountain market, 6-hour drive.
A real Arlington investor’s worked example
A defense-prime IT principal earning $385K + $80K bonus, residing in Arlington (spouse is part-time at home managing two kids and a small consulting practice), buys a 2BR 30A condo for $700K with $25K immediate FF&E refresh. After $165K in land, the $535K adjusted basis includes $65K in 5-year assets (appliances, smart-home, theater equipment, beach package, decorative lighting), $24K in 7-year assets (custom furniture, beach-themed built-ins), and $72K in 15-year property (pool deck, hardscaping, fencing, beach-access lighting).
That’s $161K reclassified into accelerated depreciation in Year 1. At the federal rate (37% + 3.8% NIIT; Virginia portion deferred over MACRS), the Year-1 savings come to roughly $66,000 (about 66x the cost of the study). If the spouse claims REPS (feasible given her part-time schedule + property management hours), the deduction offsets the principal’s full W-2 income, not just the Reg. §1.469-1T(e)(3)(ii) STR-active income.
Virginia does not conform to federal §168(k) bonus depreciation, so the state share of the deduction is deferred over standard 5/7/15-year MACRS rather than taken in Year 1; the federal Year-1 benefit is unaffected. See bonus depreciation by state.
Who doesn’t qualify for cost segregation in Arlington?
REPS is structurally impossible for a full-time defense contractor or consulting principal — the 750-hour + >50% test conflicts with billable hours. If both spouses work full-W-2 jobs, only the STR exception works (7-day average + 100-hour material participation).
NoVA dual-income households where one spouse is at home or part-time have the strongest REPS-feasibility profile of any major investor metro in the country. That’s the NoVA-specific advantage worth pursuing carefully.
Frequently Asked Questions
How much does a cost segregation study cost in Arlington? For a typical $700,000 Arlington investment property, a Cost Seg Smart study runs $995. Full pricing: $495 (under $300K), $895 ($300K–$700K), $995 ($700K–$1M), $1,295 ($1M–$1.5M), $1,595 ($1.5M–$2M), $1,995 ($2M–$3M), $2,495 ($3M–$4M), $3,995 ($4M–$6M), $5,995 ($6M–$8M), $7,995 ($8M–$10M).

All studies delivered in under one hour with the CPA-Ready Guarantee — full refund if your CPA can’t use the report.
How is Arlington different from DC for cost-seg purposes? The federal portion (37% + 3.8% NIIT) is identical, and it drives the Year-1 benefit: a $161K accelerated-depreciation deduction yields ~$66K in federal Year-1 savings either way. The state portion differs (VA 5.75% vs DC 10.75%, a 5-percentage-point spread), but neither Virginia nor DC conforms to federal §168(k) bonus depreciation, so the state share is deferred over standard MACRS in both. The state-rate difference shifts the eventual deferred recovery, not the Year-1 number.
Does VA conform to federal bonus depreciation? Virginia does not conform to federal §168(k) bonus depreciation. The federal Year-1 deduction is fully available; the Virginia share is not accelerated and recovers over standard 5/7/15-year MACRS (deferred, not lost). Confirm specifics with your CPA.
Are there cleared-investor restrictions on cost-seg studies? No — cost segregation is a depreciation classification, not a financial holding. Standard SF-86 disclosure covers property ownership directly. The cost-seg study itself doesn’t create a reportable financial relationship.

How should Arlington, VA + Northern Virginia investors choose a cost segregation provider?
For a Arlington, VA + Northern Virginia investor buying a property in the $700,000 range, the choice of study provider is the single biggest controllable variable in the ROI. The methodology is fixed by IRS Audit Techniques Guide rules (industry-standard construction cost data, MACRS classification, engineering-based component reclassification) — what varies is delivery cost and turnaround time.
Traditional engineering studies often run several thousand dollars and can take several weeks, because they include on-site inspections, sales discovery calls, and scheduling overhead. The IRS Cost Segregation Audit Techniques Guide does not require a physical site visit; it requires engineering-based classification with industry-calibrated cost derivation and component-level documentation.
Modern automated providers (such as Cost Seg Smart) deliver the same IRS ATG–aligned study for $495–$1,595 in under one hour, using satellite imagery, county assessor data, and the same industry-standard construction cost databases. For a Arlington, VA + Northern Virginia investor at the metro's combined bracket, that cost delta typically exceeds the study cost itself by several times over. The CPA-Ready Guarantee (full refund if the report can't be used by your CPA) plus the 60-day money-back policy makes the decision essentially risk-free on the report itself.
The automated path is best-fit for Arlington, VA + Northern Virginia investors who: own residential STR property valued under $2M, are comfortable uploading closing docs + property photos online (no in-person visit required), and want the report in time to file the current year's return rather than the next one.

|---|---|---|
| <$300K | $495 | Traditional engineering firms typically charge several thousand dollars per study, with a 4–8 week turnaround and an on-site visit. |
