How Makpar Supports the IRS in the Wake of the One Big Beautiful Bill

The recently passed One Big Beautiful Bill places a priority at the Internal Revenue Service (IRS) on reforming the taxpayer experience, improving internal efficiencies, and codifying new changes to tax law and policy. However, without new funding or additional staff, the IRS must implement these changes against a backdrop of lean teams and ruthless prioritization.

At Makpar, we believe the answer to these challenges lies in data sharing initiatives that unlock efficiency and transparency. By streamlining how information is exchanged across systems and organizations, the IRS can improve taxpayer services while reducing the burden on staff and resources.

Why Data Sharing Matters for the IRS

The Bill calls for a more connected and responsive IRS, specifically calling for new integrations with Department of Education, simplifying reporting, and improving due diligence analysis. Data sharing is central to this mandate. When information flows securely across the agency’s business units and partner agencies, it enables faster taxpayer services, more consistent compliance, and greater transparency that strengthens public trust.

Makpar has extensive experience supporting these outcomes:

• Enabled modernization of systems that support more than 85,000+ IRS personnel and 133,000+ million taxpayers.
• Direct experience working with all 28 IRS business units, developing integrations with over 36+ IRS applications, and implementing security solutions across 120k+ endpoints at 512 IRS sites. 
• Established the secure channel for all external-facing applications to greatly improve the overall Taxpayer Experience.

We understand both the technical and organizational challenges of modernizing systems at this scale, and we know how to deliver solutions that make data work for mission success.

Connecting to Makpar’s Technology Roadmap

Makpar’s capability-led technology roadmap aligns directly with the IRS mission. Several of our roadmap initiatives support more effective data sharing:

• Decision Intelligence: We build platforms that unify information across IRS business units, providing leaders with consistent, accurate data to guide decision-making.
• Reusable Government Blueprints: Our FedRAMP-ready reference architectures can be cloned, extended, and scaled, enabling the IRS to replicate secure and proven data flows across programs.
• Digital Identity and Policy-as-Code: We engineer secure, seamless identity systems that allow for real-time authorization and easier data exchange between platforms. This reduces friction for both taxpayers and IRS personnel.

By applying these capabilities, we help the IRS move away from fragmented, legacy systems and toward a more integrated, efficient, and transparent model of operation.

Building a More Transparent IRS

The One Big Beautiful Bill has set an ambitious path forward. By focusing on data sharing initiatives, the IRS can improve compliance, strengthen transparency, and deliver better taxpayer experiences, all while managing limited resources.

Makpar is ready to help. With deep expertise in federal modernization, proven frameworks for secure data sharing, and a roadmap designed for mission alignment, we can support the IRS in turning this legislative challenge into a moment of transformation.
