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.
- $161,000 Accelerated Depreciation (typical STR worked example)
- $66,000 Est. Year-1 Tax Savings (37% + 3.8% NIIT; Virginia portion deferred over MACRS)
- 66x Return on Study Cost

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 representative $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). Commercial and 5+ unit multifamily studies start at $1,995; 2–4 unit multifamily from $795. 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.

Representative scenarios modeled via Cost Seg Smart's proprietary
engine — IRS ATG-aligned methodology, industry-standard 2026 construction cost data base costs,
calibrated metro multipliers. n=50 fixtures matched to
Arlington, VA + Northern Virginia investor profile. Not derived from individual
client returns. Methodology v1.0.0, generated
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 July 2026. Federal: OBBBA restored 100% bonus depreciation under §168(k), permanent for property both acquired and placed in service after January 19, 2025 (property acquired or placed in service on or before that date remains under the prior 40% phase-down); 2026+ stays 100%. State conformity varies; verify with your CPA.
CPA use note: These figures estimate the size of the depreciation deduction. Whether the loss is usable in the current year depends on passive-activity rules, STR material participation, REPS status, entity structure, depreciable basis, and state conformity — your CPA decides how and when it is applied. Specialty and site components (equipment, casework, docks, pools, arenas, tenant improvements, and similar) are only classified when you own them and they are included in the depreciable basis being studied.
How should Arlington, VA + Northern Virginia investors choose a cost segregation provider?
For an 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 an 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.
All Cost Seg Smart studies include the CPA-Ready Guarantee (full refund if your CPA can't use the report) plus a 60-day money-back policy. Reports are delivered in under one hour with no on-site visit required.
