COMMON QUESTIONS CLIENTS ASK ABOUT COMPANY AND LLC TAX RETURNS

WHICH COMPANIES REQUIRE A TAX RETURN?


Company tax returns are needed for businesses who have incorporated as either a C-Corporation or S-Corporation. Corporate structures can have significant tax advantages since these structures allow the corporation to pay tax on profits instead of the owner. We can help you assess the best structure for your business to reach the goals and tax effective outcomes you desire.

HOW IS A COMPANY TAXED?


C-Corporations pay tax on all profits, minus any deductions. S-Corporations have the option to choose to be taxed as a corporation or as a partnership where the business is treated as a “pass-through entity”. Under the latter the profits are passed on to the owners and taxes are collected via the individual partners’ personal tax returns.

WHEN IS A COMPANY TAX RETURN DUE?


Company tax returns are typically due on March 15th each year, however, companies may request a six-month extension. If your company has more than $10 million in assets you must file the tax returns online. We can file online on behalf of your business, but all the paperwork must be filed electronically. Companies are also able to make installment payments in April, June, September and December.

INFORMATION INCLUDED ON COMPANY AND LLC TAX RETURNS

Your company tax return must include details of the company’s profits and expenses. The net result determines the amount of tax the company owes to the US government. Included in the return are several schedules that detail information such as the costs of goods sold, dividends and deductions, officer compensation, details about the accounting method used, business type, NAICS classification number, balance sheets, and the reconciliation of income and loss.

As tax professionals, we ensure your company tax return is prepared properly, keeping you protected from the risk of audit, while ensuring you maximise your tax claims. 

 
 

Information and Documents for Company and LLC Tax Returns

 

To complete your company tax return you need to include personal details such as the name, address, employer ID number, date of incorporation, and the total assets. 

The corporate financial officer will need to supply details about the corporate income including:

  • Gross receipts
  • Cost of goods sold
  • Dividends
  • Interest
  • Rents
  • Royalties
  • Capital gains

WHAT EXPENSES CAN I DEDUCT ON COMPANY AND LLC TAX RETURNS?

Companies are able to claim many tax deductible expenses against income. As experienced tax professionals, we will assess the deductibility of your expenses to ensure your claims are valid and effective.

The financial officers of the corporation should be tracking these details throughout the year and be able to supply full documentation in the case of an audit.

Without adequate documentation you risk failing an audit. The deductible expenses include:

  • Officer compensation
  • Other salaries
  • Repairs and maintenance
  • Rents
  • Taxes and licenses
  • Interest expenses
  • Charitable contributions
  • Depreciation
  • Advertising
  • Pensions and profit sharing plans
  • Employee benefit programs
  • Domestic production activities
  • Other miscellaneous deductions
 
 

SPECIAL RULES FOR FOREIGN INVESTORS

If you are a foreign investor who owns a US corporation, you are required to file US company returns. Since foreign ownership can introduce complex tax issues it is important to engage a qualified and experienced international tax expert.

We provide advice to non-US residents who are starting, running, or transitioning a US corporation. To ensure your company is in the best position possible, it is important to talk to us as early as possible. This means you should seek advice when opening a business in the US as well as when filing taxes.

Under US tax law, non-residents may own shares in a C-Corporation. These shareholdings may subject you to double taxation of profits at the corporate level and at the personal level for dividends when these are paid out to shareholders. Alternatively, LLCs will pass on all the profit to the owner, who will then need to file personal tax returns with the IRS.

THE DEBATE AROUND USA TAX RATES

The United States has some of the strongest global markets, but some argue that it also levies the highest corporate tax rates among developed nations. There is debate on whether or not the US corporate tax rate is actually higher, especially when all of the deductions and credits are taken into account.
