If you earn a W-2 in cleared-tech, AWS GovCloud, Microsoft Federal, Palantir, or anywhere in the Tysons / Reston / McLean tech corridor, you face federal 37% + NIIT 3.8% + VA 5.75% = ~46.5% combined, the same NoVA bracket as Arlington but with a notably different employer profile.
- $165,000 Accelerated Depreciation (typical STR worked example)
- $67,000 Est. Year-1 Tax Savings (37% + 3.8% NIIT; Virginia portion deferred over MACRS)
- 67x Return on Study Cost

The Tysons / Reston tech corridor profile
Tysons + Reston is distinct from Arlington within NoVA: heavier tech-contractor and cleared-tech concentration, less defense-prime-heavy, more equity-based comp:
- Cleared tech and gov-tech (Palantir Tysons, AWS GovCloud Herndon, Microsoft Federal Reston, Anduril DC, ID.me Tysons): $300K–$1.2M+ with equity
- Senior cloud and SaaS (Salesforce Government Cloud, Snowflake Federal, Databricks Federal, MongoDB Atlas Federal): $400K–$1M+ with RSU
- CapTech, Booz Allen, Accenture Federal senior consulting (overlap with Arlington, but more concentrated in Tysons/Reston for the tech-services practices): $300K–$900K + bonus
- Tech-prime engineering executives (Northrop Grumman senior tech, Lockheed Martin senior systems engineering): $300K–$1.2M with equity
The combined marginal-rate stack:
- Federal: 37%
- NIIT: 3.8%
- Virginia: 5.75% (top rate)
- Combined: ~46.5%
The 5 percentage point gap vs DC residents is a meaningful structural advantage for Tysons buyers: over a 10+ year hold + 100% bonus depreciation Year-1 deduction window, the gap 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 the Tysons corridor
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 Tysons corridor advantage vs Arlington: more equity-based comp (Palantir RSU, AWS RSU, Microsoft Federal RSU) means cost-seg deductions can be timed against vesting cliffs. The equity-vesting timing strategy that Palo Alto and Bellevue use applies in Tysons/Reston for the cleared-tech equity-comp employee.

Where do Tysons-corridor investors buy property?
Tysons / Reston 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.
- 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.
The Tysons → 30A pipeline is the most visible: Florida 0% state tax + premium beachfront + direct IAD flights aligns with cleared-tech equity-vesting investors who want a vacation property to deploy RSU cashout against.
A real Tysons investor’s worked example
A Palantir Tysons senior engineering principal earning $385K base + $200K RSU vesting + $75K bonus, residing in McLean (spouse non-W-2, part-time managing a small consulting practice), buys a 3BR 30A condo for $725K with $25K immediate FF&E. After $175K in land, the $550K adjusted basis includes $66K in 5-year assets (appliances, smart-home, theater equipment, beach package, decorative lighting), $25K in 7-year assets (custom furniture, beach-themed built-ins), and $74K in 15-year property (pool deck, hardscaping, fencing, beach-access lighting).
That’s $165K 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 $67,000 (about 67x the cost of the study). If the spouse claims REPS (feasible at part-time consulting + property management hours), the deduction can offset the principal’s full W-2 income, not just 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 Tysons-corridor?
REPS is structurally impossible for a full-time cleared-tech principal or senior engineer: the 750-hour + >50% test conflicts with cleared-work hours and on-call rotations. If both spouses work full-W-2 jobs, only the STR exception works (7-day average + 100-hour material participation).
NoVA’s dual-income households where one spouse is at home or part-time have a meaningfully better REPS-feasibility profile than NYC or Bay Area equivalent investors. The Tysons corridor’s higher concentration of dual-tech-career couples (vs. dual-finance NYC) makes REPS qualification more nuanced; confirm with your CPA whether either spouse can credibly claim the test.
Frequently Asked Questions

All studies delivered in under one hour with the CPA-Ready Guarantee: full refund if your CPA can’t use the report.
How is Tysons different from Arlington for cost-seg purposes? Tax-wise, identical: both pay VA 5.75% (combined ~46.5%). Where they differ: Arlington skews defense-prime + consulting + DC-overflow; Tysons / Reston skews cleared-tech and SaaS federal with more equity-vesting comp. The cost-seg strategy is broadly similar but Tysons investors have more RSU-timing leverage.
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.

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 Tysons, VA (NoVA tech corridor) investors choose a cost segregation provider?
For a Tysons, VA (NoVA tech corridor) investor buying a property in the $725,000 range, the choice of provider is a major controllable variable in the return. The IRS Audit Techniques Guide sets the quality characteristics an engineering-based study should meet — industry-standard construction cost data, MACRS classification, and component-level documentation — but it does not make every provider's work identical; rigor, cost, and turnaround still vary.
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 prescribe an on-site inspection as a standalone requirement; it sets out the quality characteristics of an engineering-based study — component-level classification, a documented and supportable cost derivation, and a clear audit trail — and describes how a physical inspection can contribute to meeting them.
Modern automated providers (such as Cost Seg Smart) deliver an engineering-based, IRS ATG-aligned study using property records, documents, photos, and recognized construction-cost data, typically from $495 and often the same day. For a Tysons, VA (NoVA tech corridor) investor at a high combined bracket, that cost and speed difference is meaningful. 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 owners who can provide closing documents and 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. Straightforward residential studies are often delivered the same day and completed remotely; larger or more complex commercial studies take longer and may include an on-site observation.
