Tax preparation is a seasonal business, which means your client list is either a revenue engine or a liability depending on how you handle the off-season. Every year, a significant portion of your past clients goes silent. They might have switched to a competitor, moved to a different preparer, or simply forgot to book their appointment. The cost of acquiring a new tax client is significantly higher than reactivating an existing one, yet many firms ignore this low-hanging fruit because they lack the time to manually call hundreds of dormant accounts. This is where win-back and reactivation calling solutions come in. In 2026, the landscape has shifted from generic email blasts to intelligent, AI-driven voice campaigns that can handle the nuance of tax conversations. We analyzed the current market to identify the top six platforms that help tax preparation services re-engage lapsed clients. These tools range from fully managed services that handle compliance and execution to self-serve software that requires your team to manage the dialing. Below, we break down each option, focusing on their ability to handle the specific nuances of the tax industry, such as seasonal timing, compliance with calling regulations, and the need for clear, documented outcomes.
#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch.
My AI Call Center is a done-for-you managed outbound calling service that runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only. It is owned and operated by AIQ Labs, with a base in Halifax, Nova Scotia, and an operating center in Austin, Texas. The platform is designed for multi-location organizations and multi-location practices, typically serving firms with 1 to 200+ staff. For tax preparation services, the Win-Back & Reactivation Calling campaign targets clients who have been dormant for 12 to 24 months, a window that aligns well with the annual tax cycle. The service operates on a strict list discipline model. Before any campaign launches, the team reviews the list source and consent records. If a list is purchased without clear permission records, it is flagged and, in most cases, declined. This approach protects the tax firm’s reputation and ensures compliance with TCPA regulations, which is critical in the financial services sector. The company’s promise is to run more useful calls without the firm needing to build a larger call center or hire additional staff. The campaigns are structured around one clear goal per initiative, such as confirming a return or booking a re-engagement appointment. Outcomes are routed directly back into the CRM and scheduling tools the firm already uses, ensuring that hot leads are transferred live or logged for follow-up. The reporting is honest and data-driven, providing disposition codes, per-call notes, and follow-up requests without inventing metrics or testimonials. This transparency is a key differentiator for firms that need to trust their marketing data.
Pros
- Fully managed service eliminates the need for call center staff or software administration
- Strict list discipline protects against TCPA risk and wasted spend
- Transparent, locked-in pricing quoted before launch
- Outcomes route directly into existing CRM and scheduling tools
- Compliance-forward handling of AI disclosure, opt-outs, and DNC records
Cons
- Not a self-serve platform; requires a campaign review and approval process
- Only works with approved, permissioned, or reviewed lists
- Campaign pricing requires a quote; no public self-serve calculator
Best for: Tax preparation firms and multi-location practices (typically 1-200+ staff) that want compliant, fully managed reactivation campaigns on permissioned client lists without building internal calling capacity.
#2 WinbackEngine — $1,000 to start a 30-day pilot, plus 20% of net recovered revenue.
WinbackEngine is a performance-based customer reactivation service that uses trained human agents to call lapsed customers. According to their website, the service is designed for multi-location service businesses, including fitness studios, med spas, and dental practices, though the methodology translates well to tax preparation firms that prefer a human touch. The platform operates on a risk-reversal model, which is a significant differentiator in the win-back space. As of September 2026, the service costs $1,000 to start a 30-day pilot, plus 20% of net recovered revenue. They offer a 5x ROI guarantee, meaning if the service does not hit that return within 30 days, the initial $1,000 fee is refunded in full. The process involves connecting the firm's booking system or CRM, which integrates with major platforms like Zenoti, Mindbody, and Vagaro, or via CSV export. The team then builds tailored campaigns and call scripts, and agents are trained on the brand voice. The agents make personalized calls to get lapsed members to rebook appointments. For a tax firm, this means a real person is calling the client, which can be effective for high-value clients who prefer human interaction over AI. The service is reactive, meaning it focuses on recovering revenue that has already left, rather than preventing churn. It does not provide churn analytics or prevention strategies, so it is best used as part of a broader retention strategy. The eligibility for this service typically requires a business with 500+ lapsed customers and a $50+ average transaction, which most established tax firms would meet.
Pros
- Performance-based pricing aligns incentives with results
- Human agents provide a personalized, high-touch experience
- ROI guarantee reduces the risk of the initial investment
- Integrates with existing CRM and booking systems
Cons
- Commission on every recovery can become expensive at scale
- Reactive model does not address the root cause of churn
- Eligibility thresholds may exclude smaller firms
- Phone-only approach; no multi-channel strategy
Best for: Tax preparation firms with 500+ lapsed customers who prefer human callers for high-value reactivation and want a performance-based pricing model.
#3 TopCalls — $0.35 per minute, all-inclusive.
TopCalls offers AI voice agents purpose-built for customer reactivation and win-back calling. According to their website, the platform reaches dormant accounts with personalized conversations that reference each customer's history, such as last purchase, account details, and previous interactions. This personalization helps ensure that the contact hears a relevant pitch rather than a generic one. The company states its agents can reach thousands of lapsed customers daily, a pace that a human team cannot match. For tax preparation services, the most relevant capabilities include churn-risk segmentation, where uploaded lists can be split by reason for leaving, and a different script is used for each segment. The agents can also deliver targeted win-back offers and handle objections based on why the client stopped using the firm. Even when a client refuses to return, TopCalls collects the stated reason for leaving on every call, turning churn data into actionable insight for the firm. The platform supports reactivation tracking, allowing firms to measure which clients re-engaged or accepted offers. Pricing is published at $0.35 per minute all-inclusive, which the company says makes calling an entire dormant base economically viable. On compliance, TopCalls states that consent status is tracked per customer, but the firm is responsible for ensuring consent and handling opt-outs. This makes TopCalls a strong option for firms that want AI-driven scale but are willing to manage their own consent records and compliance frameworks.
Pros
- Published, transparent pricing at $0.35 per minute
- AI agents handle high volume at a pace humans cannot match
- Personalized calls reference customer history
- Collects valuable feedback from non-reactivated clients
Cons
- Firm is responsible for consent and opt-out management
- No managed service; requires internal configuration
- Pricing may be higher than per-minute rates of managed services at high volume
Best for: Tax preparation firms that want AI-driven scale for reactivation and are comfortable managing their own consent and compliance records.
#4 MarketStar — Contact for pricing
MarketStar is a customer success agency that offers tailored reactivation services for businesses looking to reclaim and reignite connections with lapsed customers. According to their website, they view lapsed customers not as losses but as opportunities for a comeback. Their approach is strategic and data-driven, beginning with a comprehensive understanding of lapsed customers through segmentation. They identify and categorize customers based on value, reasons for leaving, and potential for reactivation. The agency then crafts tailored reactivation campaigns that address the specific reasons for departure, highlighting new offerings or improvements. Their multichannel outreach strategy ensures communication reaches customers through their preferred channels, including email, direct mail, phone calls, and social media. For tax preparation firms, this multichannel approach can be beneficial, as some clients may prefer a direct mail piece or an email reminder over a phone call. MarketStar also creates customized reactivation offers or incentives at both the segment and individual levels. They incorporate feedback from past interactions to make communication more relevant and use continuous improvement principles to refine strategies. Real-time monitoring is a key part of their service, allowing them to analyze reactivation rates, customer feedback, and revenue impact. While MarketStar does not publish specific pricing for their reactivation services, their agency model suggests a higher-touch, strategic engagement that may be suitable for larger tax firms looking for a comprehensive customer success overhaul rather than just a calling campaign.
Pros
- Comprehensive, strategic approach to customer reactivation
- Multichannel outreach reaches clients on their preferred channels
- Data-driven segmentation and campaign design
- Real-time monitoring and ROI analysis
Cons
- Pricing is not published, requiring a sales conversation
- Agency model may be slower and more expensive than automated tools
- Focus is on overall customer success, not just calling
Best for: Tax preparation firms that want a strategic, multichannel customer success approach to reactivation rather than a single-channel calling campaign.
#5 Olivia (by Pete & Gabi) — Contact for pricing
Olivia is an AI sales agent built specifically to bring back lost customers, reduce customer churn, and recover revenue from dormant accounts. According to their website, Olivia handles high-volume outbound calling, qualifies intent in real time, updates CRMs, and escalates hot conversations directly to sales teams. Unlike generic AI dialers, Olivia holds natural, human-like conversations that adapt to objections, assess customer sentiment, and offer personalized win-back incentives in real time. The solution is plug-and-play, integrating easily with existing CRMs, and claims to start generating revenue within days. For tax preparation services, this means Olivia can call lapsed clients, answer their questions, and book appointments directly into the firm's calendar. The AI agent is designed to be compliance-ready, capturing consent and handling opt-outs. The platform is voice-first, which is a strength for tax firms that want to prioritize phone conversations over emails or texts. Olivia is particularly effective for revenue teams focused on customer win-back and churn reduction. However, it is a self-serve platform, meaning the firm must configure the agent, set up the escalation rules, and monitor the performance. The best results require clean escalation rules, so firms need to be prepared to manage the workflow. Olivia is a strong option for firms that want an AI agent to handle the initial outreach and qualification, with human staff taking over for complex cases.
Pros
- Built specifically for customer reactivation and revenue recovery
- Natural, human-like conversations that adapt to objections
- Fast deployment and integration with existing CRMs
- 24/7 availability without added headcount
Cons
- Self-serve platform requires configuration and monitoring
- Voice-first approach may not suit firms that want multichannel outreach
- Best results require clean escalation rules and internal management
Best for: Tax preparation firms that want an AI agent to handle high-volume reactivation calling and CRM updates, with human escalation for complex cases.
#6 Sameday — $449 a month
Sameday is an AI outbound calling platform that calls and texts through a past customer list at a pace the firm sets, in the firm's voice. According to their website, the platform is designed for any size business, with a particular focus on home services, but the technology is applicable to tax preparation firms. The service allows firms to upload their past customer list and set the calling pace, ensuring that the outreach is not too aggressive. The AI uses the firm's voice, which can help build trust with lapsed clients who may be wary of automated calls. Sameday is sold through a sales call, and the starting price is $449 a month. This pricing model is a flat monthly fee, which can be easier to budget than per-minute pricing, especially for firms with predictable call volumes. The platform is designed to book the ones who answer, meaning it focuses on immediate conversion rather than long-term nurturing. For tax preparation firms, this could be useful for a quick reactivation push before the tax season rush. However, Sameday is a sales call product, meaning it is not a self-serve tool. The firm must work with the sales team to set up the campaign and define the parameters. The platform is best suited for firms that want a simple, voice-focused reactivation tool without the complexity of a full customer success platform.
Pros
- Fixed monthly pricing is easy to budget
- Pace control allows firms to manage outreach intensity
- Uses the firm's voice for a more personal touch
- Focus on immediate booking and conversion
Cons
- Sold through a sales call, not self-serve
- Limited focus on long-term nurturing or multichannel strategy
- May not provide detailed compliance or consent management features
Best for: Tax preparation firms that want a simple, voice-focused reactivation tool with fixed monthly pricing and pace control.

Frequently asked questions
What makes My AI Call Center different from other win-back calling services?
My AI Call Center is a done-for-you managed service that runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only. It never does indiscriminate cold calling, which is critical for compliance in the tax industry. The service includes strict list and consent review before launch, ensuring that only lists with clear permission records are used. Outcomes are routed directly into the firm's existing CRM and scheduling tools, and the reporting is honest, with no invented metrics or testimonials. The pricing is transparent, with the full cost quoted before launch, and there are no per-seat charges or hidden minimums.
How much does win-back calling cost for tax preparation services?
Costs vary by provider. My AI Call Center starts at 9¢ per connected minute, tiered by volume, with a one-time setup fee and a flat monthly management fee quoted before launch. WinbackEngine costs $1,000 to start a 30-day pilot, plus 20% of net recovered revenue. TopCalls is $0.35 per minute all-inclusive. Sameday is $449 a month. MarketStar, Olivia, and other services require contact for pricing. The total cost depends on the volume of calls, the complexity of the campaign, and whether the service is managed or self-serve.
Do I need permissioned lists to run win-back calls?
Yes, permissioned lists are essential for compliance. My AI Call Center requires approved, permissioned, or reviewed contact lists and will decline lists without clear permission records. Other providers may have different requirements, but most best practices in the industry recommend using lists where you have explicit consent to contact the customer. This protects your firm from TCPA violations and ensures that your outreach is welcomed by the recipient.
Can AI win-back calls handle complex tax conversations?
AI win-back calls are best suited for initial outreach, qualification, and booking. They can handle common questions, offer incentives, and book appointments. However, for complex tax situations, it is recommended to escalate the conversation to a human preparer. My AI Call Center and other platforms like Olivia offer escalation paths where hot leads are transferred to your team or logged for follow-up. The AI handles the high-volume, repetitive parts of the conversation, freeing up your staff to focus on high-value, complex cases.
How long does it take to see results from a win-back campaign?
Results can vary, but most campaigns start generating responses within the first week. WinbackEngine states that most clients see bookings within 7 days of launch. My AI Call Center provides real-time monitoring and outcome reports, so you can track performance as the campaign runs. The speed of results depends on the quality of your list, the timing of the campaign, and the offer you present. Running a campaign before the tax season rush, such as in late fall or early winter, can often yield better results.
What is the difference between a managed service and a self-serve platform?
A managed service, like My AI Call Center, handles the entire campaign for you, including list review, script approval, launch, monitoring, and outcome reporting. You buy campaigns that are run for you, and you do not need to configure or manage software. A self-serve platform, like TopCalls or Olivia, provides the tools for you to configure, launch, and monitor the campaign yourself. Self-serve platforms offer more control but require more internal effort and expertise. Managed services are ideal for firms that want to offload the operational burden, while self-serve platforms are better for firms with marketing teams that can manage the workflow.
