The end of the year is one of the most important periods for businesses operating in the United States. Beyond evaluating sales and financial performance, it is also an opportunity to review tax obligations, organize accounting records, and prepare for the upcoming tax season.

As 2027 approaches, business owners, LLC members, and foreign investors should pay particular attention to their tax situation. Proper planning can help prevent errors, identify potential tax-saving opportunities, and avoid unnecessary penalties.

At ACMM Consulting, we recommend reviewing your company’s financial and tax position before tax return preparation begins.

Below are seven essential areas every business should consider before the end of 2026.

1. Review and Update Your Company’s Accounting Records

Accurate and organized accounting records are the foundation of effective tax planning.

Before the year ends, businesses should verify that income, expenses, bank transactions, and business activities have been properly recorded.

Key areas to review include:

• Bank reconciliations and corporate credit card transactions.
• Outstanding customer invoices and payments.
• Operating expenses and supporting documentation.
• Business loans, capital contributions, and owner distributions.
• Financial statements, particularly the balance sheet and income statement.

Reviewing these records in advance can help identify discrepancies and correct accounting issues before preparing tax returns.

The IRS emphasizes the importance of maintaining adequate documentation to support reported income and deductions.

2. Evaluate Business Expenses and Available Tax Deductions

Not every business expense is automatically tax-deductible.

The tax treatment of an expense depends on its nature, its relationship to business operations, and the applicable tax regulations.

Business owners should review expenses related to office operations, professional services, advertising, equipment, technology, and certain business-related vehicle costs.

It is also important to evaluate investments made during the year and any applicable tax provisions that may affect deductions or depreciation.

Effective tax planning is not simply about spending more to pay less in taxes. It is about making informed financial decisions supported by sound business and tax considerations.

3. Verify Your Estimated Tax Payments

Certain taxpayers, including self-employed individuals and business owners, may be required to make estimated tax payments throughout the year.

Insufficient payments may result in additional charges, depending on the taxpayer’s circumstances and applicable exceptions.

Before closing out 2026, businesses and individuals should review:

• Income earned during the year.
• Estimated tax payments already made.
• Available withholding and tax credits.
• Projected income and potential tax liabilities.

This review can help identify possible payment shortfalls and support better planning for upcoming tax obligations.

4. Review Your LLC or Corporation’s Tax Obligations

One common misconception is that all LLCs have the same federal tax obligations.

In reality, tax treatment depends on several factors, including the number of owners, tax elections made, and the entity’s classification for federal tax purposes.

Depending on the business structure, the following forms may apply:

• Form 1065: Generally used by partnerships for federal income tax reporting.
• Form 1120-S: Used by corporations with a valid S Corporation election.
• Form 1120: Generally used by corporations subject to federal corporate income tax.
• Form 1040 and applicable schedules: Used in certain situations where business income is reported on an individual’s federal income tax return.

Not every business is required to file these forms. Each entity’s tax classification and circumstances must be evaluated individually.

5. Foreign-Owned LLCs: Review Your Information Reporting Requirements

Foreign investors who own businesses in the United States should pay special attention to their federal tax and information reporting obligations.

For example, certain U.S. disregarded entities owned by foreign persons may be required to file Form 5472, together with a pro forma Form 1120, when the applicable reporting requirements are met.

This obligation may apply even when the entity is not otherwise required to file a regular federal income tax return.

Failure to comply with applicable Form 5472 reporting requirements can result in an initial $25,000 penalty, with additional penalties potentially applying in certain circumstances.

It is important to understand that Form 5472 reporting requirements are separate from the Beneficial Ownership Information (BOI) reporting requirements administered by FinCEN.

Therefore, owning an LLC in the United States requires careful consideration of the entity’s tax classification, transactions, and applicable information reporting obligations.

6. Organize Payroll Records and Payments to Independent Contractors

If your company has employees or works with independent contractors, year-end planning should also include reviewing compensation records and payments made during the year.

Businesses should verify employee information, payroll records, tax withholding, and payments made to vendors or contractors that may be subject to information reporting requirements.

Depending on the circumstances, forms such as Form W-2 or certain forms in the 1099 series may be required.

Reviewing this information in advance can help identify inaccuracies, maintain organized records, and support compliance with applicable reporting requirements.

7. Start Planning for the 2027 Tax Filing Season

Waiting until the last minute to prepare tax returns can limit opportunities to review financial information and correct potential inconsistencies.

Before the end of 2026, businesses should organize the necessary documentation, review their tax classification, identify applicable filing requirements, and establish a compliance calendar.

It is also an appropriate time to evaluate whether the company’s current business structure continues to support its operational and financial objectives.

Filing deadlines vary depending on the type of entity, its tax year, and applicable regulations.

Tax planning should be an ongoing process, not an activity that begins only when tax filing deadlines approach.

An Organized Year-End Review Is the First Step Toward a Stronger 2027

Closing the year with updated financial information and clearly identified tax obligations allows business owners to make decisions with greater confidence.

Every company has unique circumstances. For this reason, it is important to evaluate each business individually before implementing tax strategies or determining which tax returns must be filed.

At ACMM Consulting, we support business owners, LLC members, and foreign investors through accounting, tax preparation, and tax planning services, helping them maintain organized operations and meet their applicable obligations in the United States.
