Returns in full compliance with IRS regulations

We accommodate your business needs.

Is your business a Partnership, S Corporation, C Corporation or Limited Liability Company (LLC)?

Form Schedule C must be filed with your individual income tax return (Form 1040).

If you own an unincorporated business by yourself, you are a sole proprietor. If you are a single member of a domestic limited liability company (LLC) and treat the LLC as a corporation, you are not a sole proprietor. If you have multiple members of your LLC, you are most likely a partnership or an S Corporation.

Form 1065 (Form K-1) or Form 1065-B is used for a large partnership.

If you share a trade or business between two or more individuals and all members share profits and losses for the business, you are known as a partnership.

The due date is the 15th day of the 3rd month after the end of the partnership’s tax year.

Form 1120S is used for an S Corporation.

S corporations are corporations that elect to pass corporate income, losses, deductions, and credits through their shareholders for federal tax purposes.

The due date is the 15th day of the 3rd month after the end of the corporation’s tax year.

Form 1120 is used for a C Corporation.

In a C-Corporation, shareholders exchange money and/or property for the corporation's capital stock.

The due date is the 15th day of the 4th month after the end of the corporation’s tax year.
