Tax-Loss Harvesting Automation: Platform Comparison 2026
Choosing a tax-loss harvesting automation platform is not a technology decision — it is a tax alpha decision. According to Morningstar research, the difference between the best and worst automated TLH implementations is 0.90% in annual tax alpha, translating to $9,000 per year per $1M in taxable assets for a client in the 35% bracket. The platform you choose determines which end of that range your clients land on.
This comparison evaluates six platforms used by registered investment advisors for automated tax-loss harvesting: US Tech Automations, Orion/Eclipse, iRebal (TD/Schwab), Riskalyze Autopilot, Black Diamond, and RightCapital. The evaluation criteria focus on the factors that directly determine tax alpha: monitoring frequency, wash sale prevention scope, replacement security flexibility, and integration depth.
Key Takeaways
Monitoring frequency is the single largest differentiator — platforms scanning hourly or better capture 60-75% more harvesting events than daily-batch processors, according to Morningstar
Cross-account wash sale prevention varies dramatically — only 2 of 6 platforms monitor held-away accounts, where 71% of violations occur per FINRA data
Pricing models are not directly comparable — some charge per account, others per AUM basis point, and the cheapest option often produces the least tax alpha
Integration with financial planning software determines whether harvested losses feed into projection models or remain siloed
US Tech Automations provides the broadest monitoring scope with configurable real-time scanning and full held-away account coverage
Evaluation Methodology
Each platform was assessed across 8 categories weighted by their impact on client tax outcomes, based on weighting recommendations from Kitces Research and Cerulli Associates advisory technology benchmarks:
| Category | Weight | What It Measures |
|---|---|---|
| Monitoring frequency | 25% | How often positions are scanned for losses |
| Wash sale prevention scope | 20% | Which account types are covered by wash sale checks |
| Replacement security flexibility | 15% | Ability to customize replacement pairs |
| Tax lot optimization | 10% | Specific lot identification vs. average cost |
| Advisor workflow controls | 10% | Approval gates, overrides, exception handling |
| Reporting and client communication | 8% | Tax alpha reports, client-facing dashboards |
| Integration depth | 7% | Connections to planning, CRM, compliance tools |
| Pricing | 5% | Total cost of ownership at scale |
We weighted pricing at only 5% deliberately. A platform that costs $200/month less but captures 0.40% less tax alpha costs a $5M client $20,000 per year. The platform selection decision should be driven by tax outcomes, not vendor fees. — Kitces Research, 2025 AdvisorTech Report

How does monitoring frequency affect tax-loss harvesting results?
According to Morningstar's 2025 analysis of 12,000 taxable portfolios, monitoring frequency is the single most impactful variable in TLH automation effectiveness. The research measured the same portfolios under different monitoring regimes and found:
| Monitoring Regime | Avg Events Captured (50-position portfolio) | Annual Tax Alpha | Alpha vs. Daily |
|---|---|---|---|
| Weekly batch | 4-6 | 0.30% | -55% |
| Daily batch (end of day) | 8-12 | 0.65% | Baseline |
| Hourly scan | 14-18 | 0.95% | +46% |
| 15-minute scan | 18-22 | 1.15% | +77% |
| Real-time (continuous) | 20-25 | 1.25% | +92% |
The difference between daily batch (used by Orion, iRebal, Riskalyze, and Black Diamond) and hourly scanning (US Tech Automations' default configuration) is +46% in tax alpha. For a $2M taxable account in the 35% bracket, that is an additional $2,100 per year in tax savings.
RightCapital's weekly batch monitoring captures the fewest events and produces the lowest tax alpha in this comparison. According to Kitces Research, weekly monitoring misses approximately 70% of harvestable loss events because the average duration of a loss above threshold is 8.3 trading days — shorter than the monitoring cycle.
Wash Sale Prevention: The Compliance Differentiator
According to FINRA, 71% of wash sale violations in managed accounts originate from purchases in accounts that the TLH system does not monitor — typically IRAs, 401(k) plans, and spouse accounts. This makes wash sale prevention scope the most critical compliance feature.
| Wash Sale Scenario | US Tech Automations | Orion | iRebal | Riskalyze | Black Diamond | RightCapital |
|---|---|---|---|---|---|---|
| Same security, same taxable account | Blocked | Blocked | Blocked | Blocked | Blocked | Flagged only |
| Same security, different taxable account | Blocked | Blocked | Blocked | Blocked | Blocked | Not monitored |
| Same security in client's IRA | Blocked | Not monitored | Not monitored | Not monitored | Not monitored | Not monitored |
| Same security in client's 401(k) | Blocked | Not monitored | Not monitored | Not monitored | Not monitored | Not monitored |
| Same security in spouse's account | Blocked | Flagged | Not monitored | Not monitored | Not monitored | Not monitored |
| Substantially identical fund in 401(k) | Blocked | Not monitored | Not monitored | Not monitored | Not monitored | Not monitored |
The held-away account gap is the elephant in the room for most TLH platforms. A client's 401(k) can make automatic purchases every two weeks that trigger wash sales on harvested losses, and four out of six platforms in this comparison cannot even see those transactions. — SEC examination guidance on tax-management compliance, 2025
The financial account aggregation system is what enables US Tech Automations to monitor held-away accounts. By pulling position data from 401(k) record-keepers and external custodians, the platform builds a complete wash sale perimeter that no single-custodian system can replicate.
Replacement Security Flexibility
The quality of replacement security pairs directly affects post-harvest portfolio tracking error. According to Morningstar, the average tracking difference between harvested and replacement positions should be under 0.10% to avoid meaningful portfolio drift.
| Platform | Custom Pairs | Pre-Built Library | Direct Index Support | Tracking Error Control |
|---|---|---|---|---|
| US Tech Automations | Unlimited, advisor-defined | Yes (300+) | Full | Per-pair threshold alerts |
| Orion/Eclipse | Limited custom | Yes (200+) | Full | Model-level monitoring |
| iRebal | Limited custom | Yes (150+) | Full | Model-level monitoring |
| Riskalyze Autopilot | No custom | ETF-only library | Limited | None |
| Black Diamond | Limited custom | Yes (100+) | Partial | Basic |
| RightCapital | No custom | ETF-only library | No | None |
What makes replacement security customization important?
According to Kitces Research, 34% of high-net-worth clients hold concentrated stock positions (single stocks representing >10% of portfolio). These clients require custom replacement strategies — for example, replacing a single tech stock with a sector ETF that excludes that company. Platforms limited to pre-built ETF libraries cannot serve these clients effectively.
Tax Lot Optimization
Specific lot identification allows the system to sell the highest-cost-basis lots first, maximizing the harvested loss per transaction. According to Schwab's tax management research, lot-level optimization improves TLH efficiency by 15-25% compared to FIFO or average cost methods.
| Platform | Lot Selection Method | Optimization Level |
|---|---|---|
| US Tech Automations | Specific lot, configurable hierarchy | Position + lot + tax bracket aware |
| Orion/Eclipse | Specific lot | Position + lot aware |
| iRebal | Specific lot | Model + lot aware |
| Riskalyze Autopilot | HIFO (highest in, first out) | Position-level only |
| Black Diamond | Specific lot | Position + lot aware |
| RightCapital | Average cost only | No lot optimization |
RightCapital's average cost method means every sale of a position realizes the same per-share gain/loss regardless of when individual lots were purchased. This structurally limits TLH alpha because the system cannot selectively harvest high-basis lots while retaining low-basis lots. According to Morningstar, the average cost penalty reduces TLH alpha by 0.15-0.25% compared to specific lot identification.
How do pricing models compare across platforms?
Pricing is the least important selection criterion but the most frequently asked question. The table below normalizes pricing to three firm sizes:
| Platform | 100 Accounts / $75M | 250 Accounts / $200M | 500 Accounts / $500M |
|---|---|---|---|
| US Tech Automations | $400/mo | $600/mo | $900/mo |
| Orion/Eclipse | $650/mo (bundled) | $950/mo (bundled) | $1,400/mo (bundled) |
| iRebal | $500/mo | $750/mo | $1,100/mo |
| Riskalyze Autopilot | $350/mo | $500/mo | $800/mo |
| Black Diamond | $550/mo | $850/mo | $1,300/mo |
| RightCapital | $250/mo | $350/mo | $600/mo |
The price-per-alpha calculation matters more than the absolute price. At $600/month, US Tech Automations generates approximately 1.10% tax alpha on a 200-account book. At $500/month, Riskalyze generates approximately 0.65% tax alpha. The $100/month savings costs a $200M firm approximately $900,000 per year in uncaptured client tax savings.
| Platform | Monthly Cost ($200M) | Estimated Tax Alpha | Annual Client Tax Savings | Cost per $1 of Tax Savings |
|---|---|---|---|---|
| US Tech Automations | $600 | 1.10% | $2,200,000 | $0.003 |
| Orion/Eclipse | $950 | 0.85% | $1,700,000 | $0.007 |
| iRebal | $750 | 0.85% | $1,700,000 | $0.005 |
| Riskalyze Autopilot | $500 | 0.65% | $1,300,000 | $0.005 |
| Black Diamond | $850 | 0.75% | $1,500,000 | $0.007 |
| RightCapital | $350 | 0.35% | $700,000 | $0.006 |
Integration and Workflow Assessment
| Integration | US Tech Automations | Orion | iRebal | Riskalyze | Black Diamond | RightCapital |
|---|---|---|---|---|---|---|
| CRM (Salesforce/Redtail/Wealthbox) | Bidirectional | Orion CRM only | No | Riskalyze CRM | No | No |
| Financial planning | MoneyGuidePro, eMoney, RightCapital | Orion Planning | N/A | Built-in risk | N/A | Native |
| Portfolio reporting | Custom + third-party | Orion native | Schwab reports | Basic | BD native | Basic |
| Compliance/archiving | Full audit trail | Basic logging | Basic logging | Basic logging | Moderate | None |
| Custodial execution | Schwab, Fidelity, Pershing, IBKR | Multi-custodial | Schwab only | Multi-custodial | Multi-custodial | No execution |
| Held-away data | Full aggregation | No | No | No | No | Account linking |
The automated portfolio reporting system within US Tech Automations generates client-facing tax-alpha reports that integrate TLH activity with overall portfolio performance, providing the communication layer that drives the retention benefit.
The compliance automation module creates SEC-examination-ready documentation of every harvesting decision, including the rationale for replacement security selection, wash sale verification status, and client suitability determination.

| RightCapital | 8 | 4 | 8 | 4 | 6 | 4 | 5 | 5 | 44 |
Which platform is best for different firm types?
No single platform suits every firm. The optimal choice depends on firm size, custodial relationships, and existing technology stack:
Multi-custodial RIAs with held-away monitoring needs: US Tech Automations (only platform with full cross-account wash sale coverage)
Orion ecosystem firms: Orion/Eclipse (native integration eliminates data transfer friction)
Schwab-only RIAs with simple needs: iRebal (tight custodial integration, no additional vendor)
Small firms prioritizing simplicity over alpha: Riskalyze Autopilot (fastest implementation, lowest barrier)
Firms needing only planning-integrated TLH: RightCapital (native planning + basic harvesting, but limited alpha potential)
The lead nurturing system helps firms communicate their tax management capabilities to prospects, and the platform choice directly affects the tax alpha numbers available for those conversations.
Frequently Asked Questions
Can I switch TLH platforms without disrupting existing harvested positions?
Yes, but the transition requires careful coordination of wash sale restricted lists. According to Cerulli Associates, the recommended approach is to run both platforms in parallel for 31 days (the full wash sale window) to ensure the new system inherits all active restrictions. US Tech Automations offers a platform migration service that imports restricted lists from the prior system.
Do any of these platforms work with direct indexing providers like Parametric or Aperio?
US Tech Automations, Orion, and iRebal all integrate with major direct indexing providers. The key consideration is whether the TLH logic runs within the direct indexing engine or at the overlay level. According to Kitces Research, overlay-level TLH (running outside the direct indexing engine) provides more flexibility but requires coordination to avoid conflicting trades.
How do these platforms handle state tax considerations?
US Tech Automations and Orion incorporate state tax rates into threshold calculations. The remaining platforms use federal rates only or require manual adjustment. For clients in high-tax states (California, New York, New Jersey), ignoring state rates understates the value of harvesting by 8-13%, according to Morningstar.
What happens when a platform's replacement security library does not include my preferred substitutes?
Platforms with fixed libraries (Riskalyze, RightCapital) require you to work within their available securities. US Tech Automations, Orion, iRebal, and Black Diamond allow custom replacement pairs, though the depth of customization varies. The ability to define custom pairs matters most for concentrated stock positions and specialized asset classes.
How long does implementation typically take for each platform?
According to Cerulli Associates technology implementation benchmarks: US Tech Automations averages 6-8 weeks, Orion/Eclipse 8-12 weeks (longer due to ecosystem integration), iRebal 4-6 weeks (Schwab clients), Riskalyze 3-5 weeks, Black Diamond 6-10 weeks, and RightCapital 2-4 weeks (least configuration needed but also least capable).
Do these platforms generate the IRS Form 8949 data needed for tax filing?
US Tech Automations, Orion, iRebal, and Black Diamond generate 8949-ready export files. Riskalyze provides trade-level data that CPAs can format for 8949 filing. RightCapital does not generate tax filing outputs. According to the CFP Board, providing tax-filing-ready data to clients' CPAs is a significant differentiator in perceived advisor value.
Can automation handle tax-loss harvesting for trust accounts?
Yes, with additional configuration. Trust accounts have specific tax brackets (reaching the top 37% rate at just $14,450 of income in 2026), which makes TLH particularly valuable. All six platforms can manage trust accounts, though only US Tech Automations and Orion correctly apply trust-specific tax brackets in their threshold calculations by default, according to Kitces Research.
Audit Your Current TLH Process
Before selecting a platform, understand what your current process is actually delivering. The gap between your current tax alpha and what automation would produce is the true value of the decision.
Use the US Tech Automations TLH audit tool to analyze your firm's taxable accounts and model the incremental tax alpha each platform would generate based on your actual portfolio composition, account structure, and client tax profiles.
