Plug-and-play tax-filing SDKs (Software Development Kits) are a strategic solution for neobanks and SMB applications seeking to embed Income Tax Return (ITR) filing capabilities. Achieving this functionality without extensive custom development is no easy feat. With pre-built software kits, integrating tax filing functionality directly into neobank or SMB banking applications is simple. It allows users to complete tax returns without redirecting to third-party websites.
Plug-and-play tax filing SDKs and APIs enable neobanks and allied service apps to embed tax-filing compliance directly into their platforms. Instead of forcing users to export data to third-party software, these modular integrations allow the app to auto-calculate liabilities, pull tax data linked to PANs, and help consumers seamlessly submit returns.
This process relies heavily on the Electronic Return Intermediary (ERI) network framework. In India, apps cannot legally submit an ITR to the Income Tax Department unless they act as or route data through an authorised ERI. TaxBuddy is a registered ERI, helping businesses offer value-added services through its AI-assisted and expert-assisted ITR filing infrastructure.
Companies like Research 360, Jio Finance, and many others have already embedded TaxBuddy’s fax-filing solutions to increase customer retention and engagement. Read on to know the strategic benefits of integrating plug-and-play tax filing SDKs as a competitive advantage.

Rising Demand for Embedded Tax-Related Services
The rising demand for embedded tax services in India is driven by the country's rapid shift toward digitised banking and financial services. The Indian neobanking market is experiencing accelerated growth, driven by millennials and digital-native consumers who expect seamless, in-app experiences.
In 2021, neobank users totalled 6 million, while the projection for 2027 is of a massive 60 million, as per the International Journal of Research Publication and Reviews. To remain competitive in this thriving financial marketplace, mobile banking apps look to offer more than access to quick savings. Instead, the goal is to build comprehensive financial ecosystems that include investments, credit facilities, housing finance, and even tax planning and filing.
While the businesses strive to enhance user experience, customer expectations have also shifted. Neobank consumers are mobile-first users who expect convenience, easy accessibility, minimal fees, and user-friendly features – all in one place. That said, consumers often struggle with the compliance burden of tax-filing in India. Disconnected investments across portals, complicated capital gains calculations, and rising tax complexity make filing ITRs a challenge that neobanks easily can simplify.
Despite the Income Tax Department making digital tax payments easier, filling the right forms, choosing regimes, reconciling data from Form 16, TDS statement, AIS and more is often a stressful exercise. TaxBuddy’s SDK makes it easy by offering a seamless tax filing experience that keeps users on the same app. Not only does this facility drive retention, but also high user engagement throughout the tax filing season. Embedded tax services can thus function as a success strategy leading to higher account activity and lower churn rates.
SDK vs. API: What's the Difference?
A plug-and-play tax filing SDK is a pre-built package of code, documentation, and Application Programming Interfaces (APIs) that integrates tax filing capabilities into the mobile banking app quickly. Consider it as a tax-filing module that can be embedded into a specific platform without having to write separate code for it.
While APIs let two systems communicate, SDKs are more comprehensive. An SDK includes the following:
APIs for data exchange
Pre-built UI components (forms, buttons, workflows)
Documentation and code samples
Testing tools
For neobanks looking to add value to consumers, SDKs are easier to implement with ready-to-use User Interface components. There’s no need to design the entire tax filing interface from scratch. TaxBuddy’s SDK is a white-label solution, which means it merges with a mobile banking app’s identity and looks like its own product to maintain brand consistency and trust. The mobile banking app has full control over pricing, whether the goal is to offer it as a standalone service cost effectively or bundle it as a premium feature.
TaxBuddy's ITR Filing Solution: Key Features
TaxBuddy offers India's first AI-powered tax filing platform with expert-assisted support, making it ideal for embedded integration. What makes the SDK stand out is that it offers three filing modes for every user type:
Filing Mode | Best For | Key Benefit |
DIY (Self-Filing) | Salaried employees with income from limited sources | Automated checks, fastest option |
DIY Filing (AI-Assisted) | Freelancers, small business owners | Smart suggestions, error detection |
Expert-Assisted | High-net-worth individuals, complex scenarios | Real-time tax professional support |
Unlike generic portals, TaxBuddy provides expert-assisted filing to ensure accuracy and compliance. Users can consult tax professionals in real time, addressing doubts and minimising errors that may trigger notices from the Income Tax Department. Apart from this, the software prefills ITR forms, saving users significant time and cross-verifying data before submission. The advanced error-checking mechanism helps detect discrepancies in tax calculations, checks for missing deductions, and prevents errors. This is critical for neobanks because if users don’t file accurately, they may receive notices that damage their trust in the platform.
TaxBuddy seamlessly integrates with the Income Tax Department's e-Filing portal, ensuring secure data retrieval and faster ITR submission. The platform is compliant with all Indian tax regulations and uses encryption for sensitive data. TaxBuddy's white-label financial suite includes ITR Filing (DIY, AI-assisted, expert-assisted) and Tax Planning (deduction optimisation, tax-saving investments). Choosing one or both modules entirely depends on the product strategy and target customer needs.
Key Benefits for Neobanks
Adding a tax-filing layer to existing financial services can help neobanks create a comprehensive ecosystem for users with the following benefits:
Higher User Engagement and Retention
When users can file income tax returns on the app, they engage more frequently. Tax season (January to July) becomes a peak engagement period, not a churn period. Research confirms that seamless tax filing experiences keep customers coming back. For neobanks that want to boost competitive advantage, embedded tax filing is a key differentiator.
No Redirects with In-App Services
Traditional tax filing forces users to log into third-party websites. This fragments the user experience and reduces trust. With TaxBuddy's SDK, users file taxes entirely within a single app, maintaining brand consistency and credibility.
Reduced Development Time
Building a tax filing system from scratch takes approximately 6–12 months and requires specialised tax expertise. With TaxBuddy's SDK, integration takes weeks, not months. Small and medium businesses can benefit from the following:
Pre-built UI components
Ready APIs
Documentation and support
This frees the development team to focus on other core features instead of compliance-heavy tax logic.
More than a Value-Add
Users compare neobanks on overall convenience, not just interest rates. When the app offers ITR filing, tax planning, and wealth management in one place, the app becomes a complete financial wellness suite. Embedded tax services help neobanks build a comprehensive ecosystem, not a single-product platform.
Advantages of Tax-Filing SDKs for Small and Medium Businesses
Embedded tax-filing services also help small and medium-sized businesses boost their offerings. Here are some business segments that can enhance their customer proposition:
Payroll and Employee Benefits Platforms
Platforms related to human resource management already deal with tax-related information, such as Form 16 and perquisites. Embedding tax-filing services allows them to offer users tax-filing as the next step in the journey. This high-value employee benefit can drive platform stickiness.
Freelancer Marketplaces
Marketplaces that pay out to freelancers, influencers, and gig workers can simplify complex tax scenarios by offering built-in ITR filing. Instead of users getting frustrated with how to report income, the app can guide them with prefilled data and tailored tax assistance.
SME Accounting, Billing, and Invoicing Software Providers
Tools that handle invoices, receipts, and GST for small businesses can extend their value by integrating direct ITR filing. With users sharing income and expense data already, this layer can help business owners move from bookkeeping to tax compliance in a few clicks.
Investment and Wealth-Tech Apps
Apps that power SIPs, equity trades, and mutual funds can help users manage capital gains and losses seamlessly. Integrating TaxBuddy’s tax-filing SDK allows these platforms to convert fragmented statements into accurate returns, reducing errors and anxiety.
Lending, BNPL, and Credit Platforms
Platforms that help users get financing via loans, Buy Now Pay Later features, and credit cards can also offer tax-filing as an added service. Since they already have access to consumers’ income and repayment histories for underwriting purposes, they are well-positioned to become long-term financial partners rather than one-time credit providers.
Digital Marketplaces and B2B Platforms
Platforms that enable large volumes of business transactions can also support sellers with in-app tax filing. By connecting sales data with ITR workflows, these platforms reduce compliance friction and position themselves as long-term partners in business growth.
Financial SaaS Platforms
SaaS tools used by financial advisors can embed TaxBuddy’s infrastructure to scale their tax-filing operations. Instead of building their own e-filing stack, they can leverage a compliant, ERI-backed SDK and focus on advisory services instead of creating infrastructure from scratch.
Conclusion
In 2026 and beyond, neobanks are no longer competing only on UI or interest rates. The conversation has shifted to how well they manage the full lifecycle of a user’s money—earning, spending, investing, and staying compliant with taxes. Tax filing sits at the heart of this lifecycle, yet it is often where the user journey breaks.
Plug-and-play tax filing SDKs solve this gap. By integrating TaxBuddy’s ERI-backed, AI- and expert-assisted ITR infrastructure, neobanks can turn a challenging external task into a smooth, in-app experience. Users stay on the platform, file accurately, and return each year.
For product and growth teams, this is a clear win: faster time-to-market, stronger retention, and a differentiated value proposition in a rapidly expanding neobank landscape. If you’re building the next generation of mobile digital banking, now is the right time to evaluate embedded tax filing. Explore TaxBuddy’s SDK and white-label solutions to turn tax season into a driver of engagement, loyalty, and long-term revenue.
