There are many complex regulations to consider, and overlooking any of them can cost you dearly.

We will work with you to create a business tax plan that minimizes business taxes you may owe, while improving your cash flow. This includes federal, state, and local taxes, as well as income taxes, sales, property, and payroll taxes. Each of these taxes has its own set of rules and regulations, so it's important to work with tax advisors who understand them all. Our corporate tax professionals work with tax departments, business owners, and tax attorneys to minimize our client's income taxes.

International Business Tax Compliance

International business tax compliance is a process that companies use to meet their tax obligations in multiple jurisdictions. The compliance process requires the accurate and timely filing of global tax returns, payment of taxes, and disclosure of information to tax authorities. Businesses face many challenges when complying with corporate global tax laws. They must manage a complex web of regulations and requirements, often in multiple languages. They must also keep up with changing laws and regulations and adapt their compliance processes accordingly.

The cost of non-compliance can be significant. For the last 30 years, H&CO has been preparing international tax returns and information returns for private companies doing business in the United States and abroad. We provide services through a global network of tax professionals who can meet your international tax needs.


Global Information Reporting

As businesses become more global in their operations, they are subject to an increasingly complex web of regulations. One area of compliance that has become more challenging in recent years is information reporting. Businesses must now report a variety of information to tax authorities around the world, including financial data, employee information, and details about their operations. Our tax professionals have been helping international businesses and their tax departments with their global information reporting requirements. H&CO can help you navigate the complex world of global information reporting.

We will work with you to ensure that you comply with all local, state, federal, and international reporting requirements. We will file the required forms and reports, such as Form 5471 - Information Return of U.S. Persons With Respect To Certain Foreign Corporations, Form 8865 - Return of U.S. Persons With Respect To Certain Foreign Partnerships, Form 926 - Return by a U.S. Transferor of Property To a Foreign Corporation, and Form 8992 - U.S. Shareholder Calculation of global Intangible Low-Taxed Income (GILTI).


US Tax Reform Services

There has been significant tax law changes to the US tax code, including reducing corporate tax rates, changing how income is taxed for multinational companies, and eliminating many deductions and credits. Businesses must be aware of these tax changes and how they affect their businesses. The impact of these changes affects businesses of all sizes and in all industries. The tax risk of not knowing or ignoring tax law changes can be devastating for small and large businesses.

We help you understand these tax changes by giving you advice and showing you how new laws will affect your business. We also help you understand the effect of the changes on your business, analyze your options, set a new strategy, execute the strategy, and monitor your tax plan. We can help you with a range of tax reform services, including:

• Reviewing your business operations to determine the impact of tax law changes
• Identifying opportunities to maximize the benefits of the new law and minimize taxes
• Planning for future years in light of the changes
