Tax Preparation Strategies Every Finance Team Should Know

Tax preparation has entered a new phase. Regulatory modernization and expanding digital requirements are fundamentally reshaping how the finance function manages tax compliance. For your team, the shift is clear: tax preparation is no longer a seasonal reporting exercise. It’s an operational discipline that must be embedded into core finance processes year-round.

Recent legislative and regulatory developments in the US, including updates tied to the One Big Beautiful Bill Act (OBBBA) and broader federal digitization efforts, reflect a consistent new direction for finance: fewer manual processes, more automation, and stronger data integrity. Organizations that continue to rely on disconnected systems or manual workflows face increased exposure to errors, notices, and audit friction.

This changing tax environment demands a practical, systems-oriented approach grounded in accuracy, automation, and tax readiness.

What’s Changing in Tax Compliance

The first thing finance teams need to understand is that the IRS itself is becoming increasingly digital and data-driven. Additionally, there are now higher reporting thresholds and evolving information returns that will directly alter filing volumes and tax compliance priorities. For example, some recent changes include:

• Increased 1099 Thresholds: Under the OBBBA, the reporting thresholds for Forms 1099-NEC and 1099-MISC are set to rise from $600 to $2,000 for the upcoming tax year. This significantly reduces the volume of filings for small- to medium-sized engagements.
• 1099-K Reversion: The threshold for third-party settlement organizations (like payment apps) has reverted to the original $20,000 and 200 transactions, rolling back previous attempts to lower it to $600.

These adjustments reduce filing volume for some organizations while increasing the importance of accuracy for transactions that remain reportable. This also means the IRS receives expanding third-party data streams directly from payment processors and marketplaces, making discrepancies more visible and easier to flag.

Following Executive Order 14247, the IRS has also effectively phased out paper checks for most refunds and is aggressively moving toward mandatory electronic payments for all business-to-government transactions.

For finance teams, this marks a key structural shift: as tax requirements evolve and digital processes expand, success depends less on filing season execution and more on the strength of your everyday financial workflows.

The Shift to Year-Round Tax Preparation

A decade ago, tax preparation was largely about producing reports. Today, it is about ensuring that internal systems reconcile seamlessly with external data streams. What was once a year-end process has become a continuous operational responsibility. In practical terms, this structural shift requires that:

• Supplier data is accurate and validated.
• Every payment is fully traceable.
• Supporting documentation exists before an auditor requests it.

What’s changing isn’t just the volume of data—it’s the integrity of that data. Manual reconciliation and spreadsheet-based workflows are no longer sufficient tracking mechanisms. Auditors expect system-generated histories showing what was changed, when, and why. Manual processes across disconnected systems slow this reporting capability and complicate the process.

This shift mirrors broader industry commentary. Today’s analysts frequently emphasize that finance leaders are moving toward integrated automation platforms that seamlessly blend compliance, controls, and operational workflows, rather than treating them as separate entities. This trend isn’t just about efficiency—it’s about readiness. In other words, tax preparation now starts at a transaction’s inception, not just during filing season.

Tax Preparation Strategies for Finance Teams

With regulatory requirements evolving continuously, tax preparation is no longer a seasonal task. It’s a year-round discipline that should be embedded in everyday finance processes. To maintain data integrity, tax compliance, and audit readiness, your team should focus on improving critical operational areas, including:

1. Centralizing Supplier Data

Accurate tax reporting starts with clean supplier data, which means controls must begin at the onboarding stage rather than during filing prep. Finance teams that standardize supplier information upfront reduce reconciliation issues later and create a stable foundation for reporting accuracy. Start with:

• W-9/W-8 Onboarding: Use an automated supplier portal that requires tax form validation (W-9 for US and W-8 for international) before a supplier can submit an invoice. Mandatory upfront checks reduce downstream filing errors.
• TIN Matching: Automate Taxpayer Identification Number (TIN) matching against IRS records to validate supplier information in real time. Early verification helps prevent B-Notices and penalty exposure caused by mismatched taxpayer data.

When supplier data is validated at entry, tax preparation shifts from reactive correction to strategic control.

2. Implement Touchless Tax Compliance

Manual reviews should be reserved for exceptions, not routine transactions. Standardized automation rules allow finance teams to enforce policy consistently while improving speed and reducing the likelihood of human error. Prioritize:

• Automated Three-Way Matching: Improve reconciliation between purchase orders (POs), receiving reports, and invoices. If values match within a defined tolerance (e.g., 1%), the transaction should move to payment without manual intervention. This strengthens consistency while improving processing speed.
• Automated Tax Coding: Configure your accounts payable system to apply the correct GL and tax codes automatically based on supplier type, category, and jurisdiction. Standardized rules reduce classification errors and improve reporting accuracy across entities.

Touchless tax compliance will move your key finance processes, such as accounts payable, from manual checkpoints to automated workflows that enforce data accuracy.

3. Use AI for Fraud and Anomaly Detection

AI is increasingly being used to strengthen transaction-level controls by identifying risks that traditional manual workflows may miss. Instead of replacing human oversight, AI enables finance teams to focus attention on transactions that genuinely warrant investigation. Consider:

• Behavioral Monitoring: AP platforms with advanced technology can analyze historical supplier activity to flag unusual patterns, such as sudden bank account changes or invoice amounts that deviate significantly from past behavior.
• Duplicate Detection: AI tools can identify potential duplicate invoices even when invoice numbers vary slightly (e.g., “INV-101” versus “101”), thereby minimizing errors and avoiding costly recovery efforts.

By surfacing anomalies early, advanced automation and AI can enhance data accuracy and strengthen payment processes without increasing your team’s workload.

4. Prepare for Digital Audits

Audit expectations have shifted toward digital, technology-provided evidence, requiring finance teams to maintain continuous documentation rather than reconstruct records after the fact. Your team should assume that auditors will expect system-level transparency for every transaction. Establish:

• Digital Audit Trails: Ensure systems capture every step of a transaction’s lifecycle, from invoice submission through approval and payment, creating a clear record of decisions and approvals.
• Cloud-Based Record Retention: Maintain IRS-compliant digital records, typically retained for multiple years, in searchable, indexed cloud storage. Centralized records reduce audit response time and improve documentation consistency.

Organizations that build digital tax readiness into everyday workflows reduce disruption during audits and strengthen confidence in the accuracy of their reporting.

Advice for Surviving Tax Season

With ever-changing regulatory requirements, tax season can feel demanding, even for the most experienced finance teams. But beyond the systems, thresholds, and filings, it’s really about how you manage your people and priorities. From my experience, a few simple principles make a big difference:

1. Plan ahead, even in small ways. Identify your key deadlines, high-volume suppliers, and tricky transactions early.
2. Keep your team aligned. Clear roles, regular check-ins, and a shared understanding of priorities prevent last-minute confusion and errors.
3. Focus on what matters. You can’t control everything. Concentrate on improving the processes that are the most manual and the areas where mistakes are most costly.
4. Trust your systems and your people. If you’ve implemented reliable technology solutions, validated your data, and have an engaged team, you’re already ahead.

The reality is that this new phase of tax compliance isn’t temporary. Regulatory modernization and digital-first expectations are redefining what the process looks like. By focusing on foundational strategies, like embedding tax compliance into daily operations, prioritizing data integrity, and leveraging automation and AI, tax preparation can evolve into a year-round discipline. For finance teams, the real advantage lies in a function that is always ready for tax season.
