Republican nominee Donald Trump and running mate JD Vance are campaigning on a grab bag of tax cut proposals that could collectively cost as much as $10.5 trillion over a decade, a massive sum that would exceed the combined budgets of every domestic federal agency.
Even if Congress were to eliminate every dollar of non-defense discretionary spending — projected to be $9.8 trillion over the next 10 years — it still wouldn’t offset the estimated expense of the wide-ranging tax cuts Trump and Vance have floated in recent weeks.
The price tag is based on rough, initial estimates from tax and budget specialists because the Trump campaign hasn’t released detailed policy plans for its tax promises.

The Trump campaign said in a statement the former president will cut wasteful spending and increase energy production to pay for the tax cuts and lower the national debt. The campaign didn’t offer more detail.
Though Democrat Kamala Harris also has proposed a few large tax cuts — she would exempt tips from taxation and expand the child tax credit — the impact on the nation’s finances pales in comparison. She calls for offsetting the lost income, which one think tank estimates at $2 trillion, with tax increases on corporations and wealthy individuals.
The sheer magnitude of the Trump campaign’s tax promises make it highly unlikely they all would pass even in a Congress controlled by Trump allies. The Republican ticket’s tax proposals include extending Trump’s 2017 tax cuts, a big expansion to the child tax credit and exemptions for tips and Social Security payments.
“Congress is not going to pass a $10 trillion deficit-financed tax cut,” said Kyle Pomerleau, a senior fellow with the right-leaning American Enterprise Institute.
Republicans have long argued that tax cuts boost growth. But it’s not clear how much Trump’s proposals, which largely cut levies for individuals rather than businesses, would spur new economic activity.
The combined cost of the Trump plans is so big that if Congress were to try to pass the tax cut proposals and keep spending flat, it means they could continue to fund the military, federal benefit programs, like Social Security, pay interest on the debt — and nothing else. That means eliminating major federal agencies that handle duties such as law enforcement, border security, air traffic control, tax collection and international relations.
Harris and President Joe Biden released a detailed budget proposal this year to cut federal deficits $3 trillion over a decade, by raising taxes on corporations and wealthy individuals and other measures. Those plans mirror some of the offsets Harris has proposed but previously have run into powerful opposition from major business lobbies.
Without those compensating tax increases, the Harris proposals could increase the deficit by as much as $2 trillion over the next decade, according to the University of Pennsylvania Penn Wharton Budget Model.
Trump’s supporters are accustomed to his impromptu, broad-stroke policy pronouncements, while key Democratic constituency groups demand detailed policy proposals and a firm plan offsetting the cost.
Harris is continuing to roll out policy ideas piecemeal. On Tuesday, she called for an expanded deduction for start-up businesses and her campaign has signaled that more policy plans could be released in the coming weeks.
Tax agenda
For both candidates, much will hinge on how well their party does in congressional elections, said Wendy Edelberg, a former Federal Reserve and Congressional Budget Office economist who’s now director of the Brookings Institution’s Hamilton Project.
The outlook “depends on a million different factors, particularly the balance of power in Congress,” Edelberg said. “Perhaps no policy will get enacted as specifically proposed by either candidate.”
Taxes will be a top agenda item in Congress next year, regardless of who wins the White House or which party controls the House and Senate. Major portions of Trump’s 2017 tax cuts — including lower individual rates and deduction for small businesses — expire at the end of 2025, which will force Congress to address the tax code next year.
Trump has made extending his signature tax law the centerpiece of his agenda. The Congressional Budget Office says that would cost $4.6 trillion over ten years. He’s also floated lowering the corporate rate to 15% from 21%, adding another $874 billion to the total, according to a budget model by the Committee for a Responsible Federal Budget.
On the campaign trail, the Republican ticket has verbally floated more tax ideas with hefty price tags: excluding Social Security payments from taxes ($1.8 trillion), exempting taxes on tipped wages ($250 billion) and increasing the $2,000 child tax credit per child to $5,000 ($3 trillion).
Added all up, that’s $10.5 trillion. If Congress were to seriously consider these ideas, official federal scorekeepers would model out the effects, including how the tax cuts interact with one another.
Revenue raisers
Trump has offered very few options to raise more federal revenue. He’s vowed to block any cuts to Medicare and Social Security benefits and has called for an increase in military spending. He’s proposed universal tariffs ranging from 10-20%, which on the lowest end of the spectrum could bring in $2.8 trillion over ten years, according to the left-leaning Urban-Brookings Tax Policy Center.
That has the potential to cover some of the cost of his tax cuts, but doesn’t take into account what economists warn are large negative economic growth effects or the cost of compensating farmers for trade retaliation from other countries.
The rising national debt is already stoking concern among investors and ratings agencies.
Federal Reserve Chair Jerome Powell has warned that higher government budget deficits are on an unsustainable path. In November, Moody’s Investors Service signaled it could downgrade the U.S. from the highest investment grade, Aaa.
CBO projects federal debt held by the public will exceed 100% of the GDP next year and rise to 122% in ten years without any new tax cuts.
“The fiscally responsible thing for either candidate to do, if they are proposing tax cuts, is to tell us how they are going to pay for them,” said Keith Hall of George Mason University, who once led the nonpartisan CBO.
The accounting profession is undergoing a fundamental structural transition as enterprise finance departments shift from periodic month-end closes toward automated continuous accounting models. By integrating specialized machine learning algorithms directly into enterprise resource planning (ERP) platforms, chief accounting officers are transforming financial reporting from a retrospective exercise into a real-time operational asset.
The Shift from Periodic Close to Continuous Financial Reporting
Traditional accounting workflows heavily relied on manual data reconciliation, spreadsheet calculations, and multi-week closing cycles at the end of each fiscal period. In contrast, continuous accounting frameworks utilize automated software agents to process, validate, and post transactional data in real time as business activities occur.
Automated bank reconciliation tools cross-reference incoming bank feeds, invoice records, and purchase orders automatically. By resolving transactional variances instantly throughout the month, corporate accounting teams eliminate the traditional workload spikes associated with quarterly and annual closes.
Machine Learning in Audit Trails and Anomaly Detection
Advanced natural language processing (NLP) and machine learning tools are redefining internal audit and financial control environments. Automated systems analyze 100% of general ledger entries, identifying anomalous transactions, duplicate payments, and unauthorized journal entries in real time.
Rather than relying on random statistical sampling, corporate internal auditors can focus their attention on high-risk flags automatically surfaced by algorithmic monitoring platforms. This continuous risk assessment strengthens internal controls over financial reporting (ICFR) and significantly reduces fraud risk.
Evolving Roles for Accounting Professionals
As routine data entry and manual reconciliation tasks become fully automated, the skill set required for accounting professionals is shifting toward data analysis, system design, and strategic business advisory.
– Systems Governance: Accountants are increasingly responsible for monitoring algorithmic accuracy and managing data integration pipelines.
– Business Partnership: Finance professionals leverage real-time financial dashboards to advise operational leaders on margin management and working capital allocation.
– Regulatory Compliance Management: Accounting teams utilize automated platforms to ensure compliance with dynamic tax codes and international accounting standards.
Core Implementation Recommendations
1. Deploy Automated Reconciliation Tools: Integrate continuous transaction processing modules into existing enterprise ERP architectures.
2. Establish Algorithmic Governance Controls: Implement strict internal testing protocols to ensure automated accounting rules comply with GAAP/IFRS standards.
3. Reskill Accounting Teams: Invest in training finance staff on data analytics, workflow automation, and predictive financial modeling.
Corporate accounting departments face expanding reporting expectations as international sustainability disclosure standards achieve regulatory enforcement across major global jurisdictions. Chief Accounting Officers (CAOs) and corporate controllers are establishing rigorous internal accounting controls to treat Environmental, Social, and Governance (ESG) metrics with the same data precision, auditability, and governance as traditional financial statements.
Regulatory Harmonization Under Global Sustainability Frameworks
The implementation of standardized sustainability reporting frameworks—notably rules established by international sustainability accounting boards—has created unified expectations for public and large private enterprises. Corporations must report standardized metrics covering greenhouse gas emissions (Scope 1, 2, and material Scope 3), energy utilization, workforce demographics, and supply chain governance.
In Europe and other participating international jurisdictions, double materiality principles are mandatory. Under double materiality, organizations must report both how external sustainability risks impact corporate financial performance, and how internal corporate operations affect surrounding environmental and social structures.
Integrating Sustainability Metrics into Core ERP Systems
To provide auditable non-financial data, enterprise organizations are integrating specialized carbon accounting and ESG management platforms directly into core ERP systems. Automated data collectors capture energy utility invoices, logistics fuel consumption metrics, and vendor compliance records in real time.
Establishing automated, traceable data pipelines ensures that non-financial reporting is supported by clear audit trails. This structured approach allows external financial auditors to provide reasonable assurance on sustainability disclosures during annual corporate reporting cycles.
Financial Impacts and Capital Market Disclosure
Accurate ESG reporting directly influences corporate cost of capital and institutional credit ratings. Commercial lenders and institutional asset managers systematically incorporate sustainability metrics into risk pricing models. Companies that demonstrate transparent, verifiable progress in operational energy efficiency and climate risk mitigation benefit from expanded access to green bond markets and lower debt pricing.
Action Steps for Accounting Leadership
1. Implement Double Materiality Frameworks: Conduct comprehensive assessments to identify material financial and operational sustainability metrics.
2. Build Auditable Non-Financial Data Pipelines: Automate ESG data collection within core accounting software to ensure data integrity.
3. Align Sustainability with Annual Financial Filings: Prepare non-financial disclosures concurrently with financial statements to satisfy regulatory audit expectations.
Internal audit departments and corporate risk managers are modernizing internal control frameworks by shifting from periodic sampling techniques to continuous monitoring and machine learning analytics. As operational data volumes increase across enterprise organizations, automated control testing ensures financial integrity, prevents corporate fraud, and streamlines annual audit engagements.
The Limitation of Periodic Audit Sampling
Historically, internal and external auditors evaluated internal controls by reviewing random samples of financial transactions—often analyzing less than five percent of total ledger entries. In complex enterprise environments, periodic sampling methods carry inherent risks of overlooking localized financial misstatements, unauthorized disbursements, or operational control breakdowns.
In 2026, progressive internal audit functions are utilizing automated continuous monitoring platforms that evaluate one hundred percent of financial transactions in real time. Continuous control auditing systems continuously monitor general ledger entries, procurement approvals, and expense reimbursements across all operating subsidiaries.
AI-Powered Fraud Detection and Anomaly Identification
Machine learning models trained on historical corporate financial data excel at identifying subtle transactional anomalies that indicate potential fraud or operational error. Automated systems instantly flag duplicate invoice payments, unapproved vendor creation, unusual journal entry timing, and unauthorized override of authority thresholds.
When an anomaly is detected, the automated auditing platform generates an instant risk alert, allowing internal audit teams to investigate root causes immediately. Early detection prevents minor operational errors from escalating into material weaknesses in financial reporting.
Streamlining External Audit Preparation
Continuous internal control monitoring delivers significant benefits during annual external financial audits. External audit firms can review continuous audit logs and automated control testing documentation, reducing the time required for manual field testing.
This integrated approach lowers overall audit compliance fees, reduces administrative burdens on corporate accounting staff, and provides senior management and audit committees with real-time visibility into the organization’s overall risk profile.
Core Implementation Guidelines
1. Transition to 100% Data Testing: Replace legacy sampling methods with automated continuous audit monitoring systems.
2. Deploy Anomaly Detection Algorithms: Implement machine learning models to identify unauthorized transactions and operational control overrides.
3. Align Internal and External Audit Workflows: Coordinate continuous control testing protocols with external auditors to optimize annual compliance cycles.
