President-elect Donald Trump offered up a long list of promises during his campaign, and next year will bring a major test with the upcoming expiration of many of the provisions from his first administration’s Tax Cuts and Jobs Act of 2017.
“No one has a crystal ball on what’s going to happen here, but certainly it’s a little bit clearer based on a Trump victory than it would have been based on a Harris victory,” said Brian Newman, a tax partner at Top 25 Firm CohnReznick in Hartford, Connecticut. “Obviously the big point is going to be either to extend or to make permanent TCJA provisions.”
Trump has also called for lowering the corporate tax rate, which was supposed to be made permanent with the TCJA. He has proposed to lower it to 20%, or 15% for companies that manufacture their products in the U.S.
“Going from 21% down to 20% may be a much easier sell than layering on something that would get the corporate rate down to 15%,” said Newman.
Trump has also called for bringing back 100% bonus depreciation. “Right now the bonus rate is at 40% and scheduled to go down to 20% next year,” Newman continued. “There’s been a push to get that back up to 100%. If that occurs, we’ll be talking to our clients for year-end tax planning about deciding on whether to delay placing an asset in service a month or two if, in fact, we think that we’re going to go back to 100% bonus, versus buying something this year and placing it in service this year. There are always transition rules. That’s something that we have to be cautious about. That’s something that is going to be closely watched, because it could have a significant impact on clients.”
On the other hand, parts of the TCJA could be jettisoned. Trump has also called for eliminating the act’s $10,000 limit on state and local tax deductions, also known as the “SALT cap,” for individuals, or raising it.

“It’s an easy discussion to tell clients, if you have property taxes to pay, you’re probably better off paying the property taxes January 1 versus December 31 in the hopes that something does get passed,” said Newman. “You might get a benefit for it, versus now in 2024 you know you’re not going to get a benefit.”
The treatment of R&D expenses involves another provision of the TCJA that could be eliminated. “The last couple of years, taxpayers have had to capitalize their R&D costs and then amortize them over a five-year period,” said Newman. “That’s had a significant impact on compliance and the bottom line of taxable income. Trump has said that he would like to get those expenses currently deductible again, which would be helpful for businesses that have R&D expenses.
The Section 163(j) limitation on business interest could be another area where TCJA provision would be eliminated. “Currently, your adjusted taxable income does not include adding back depreciation and amortization like it did in the first few years of the TCJA. President-elect Trump has said that he would be in favor of going back to an EBITDA calculation so that you can add back your depreciation and amortization, which would make the limitation less painful for clients. That’s another area that I think you’re going to see some tax law changes.”
Some of these business tax changes were passed by the House earlier this year as part of the Wyden-Smith Tax Relief for American Workers and Families Act of 2024 but never got through the Senate because of disagreement over other provisions, such as expansion of the Child Tax Credit.
Trump has also called for not taxing income from tips, Social Security and overtime, as well as eliminating taxes on firefighters, police officers and members of the military.
However, that could encourage people to reclassify their income as the tax-exempt kind.
“It will always be interesting to see exactly how those things work and how they’re calculated, because everyone’s always looking to maximize what income is not subject to tax or may have lower tax rates,” said Newman. “But you have to make sure that you know, things are properly defined, and that ultimately, you know, we have a clear guidance on what the calculation should be.”
Trump has also called for eliminating the stock buyback excise tax for public companies that buy back their own shares of over $1 million in a taxable year. “Right now, there’s a 1% tax on that,” said Newman. “The Biden administration has proposed increasing that to 4%, but President-elect Trump has said that he would be in favor of eliminating that tax.”
He believes the qualified business income deduction under the TCJA will also be closely watched, “People would be looking for that to either get extended or made permanent,” said Newman. “That’s a 20% deduction on certain flow-through income, which has been very beneficial to people who it applies to. Unfortunately, it does not apply, for the most part, to accountants and other professional services organizations.”
Trump has also called for doubling the standard deduction as it was in the TCJA. That could cause even fewer people to itemize their deductions. “There’s a good amount of people who don’t itemize because the SALT cap is limited to $10,000 and then if you don’t have large home mortgage interest or other itemized deductions, you’re not getting over the standard deduction threshold as it currently stands,” said Newman. “If you double the standard deduction, there will be less and less itemizers, and those types of deductions don’t become as valuable.”
That may prompt donors to reduce their charitable contributions if they can’t itemize the deduction.
Trump has also called for other tax breaks, such as tax credits for family caregivers taking care of parents or loved ones, and allowing those who buy an automobile made in the U.S. to write off the interest on their car loans.
All those tax breaks may prove difficult for states that rely on income taxes from their residents and can’t afford to let their deficits run wild. “Year after year, the state tax liabilities on transactions and income are becoming more and more a larger component of the total tax burden of both companies and individuals,” said Newman. “One of the things that states like to do is decouple from federal provisions. We always want to keep in mind, even if you get new provisions at the federal level, if they’re not already decoupled, you may get decoupled on provisions for the state. For instance, if President-elect Trump is successful in exempting, say, overtime pay, you may get a lot of states decouple from that, and the states will still tax that.”
Trump’s tax policy will also depend on what Congress does and how much control Republicans will be able to exercise, especially in the House.
“Tax was not the focal point of the campaign, and when it did emerge as an issue, former (and future) President Trump presented tax policy ideas largely in broad strokes, though he also had no small number of new ideas for voters to consider,” said Jonathan Traub, managing principal and tax policy group leader at Deloitte Tax LLP, in a statement. “Of course, tax legislation generally originates in Congress, not the White House, so any new tax laws enacted will bear the imprint of the legislative branch with its many competing interests and priorities. And, just as importantly, the ability of the Republicans to use budget reconciliation to fast-track major tax and spending bills to the White House depends on the outcome of a handful of uncalled House races around the country.”
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.
