IRS Form 3800

Form 3800, known as the “General Business Credit,” is a form taxpayers use to calculate and claim the total amount of business credits for which they are eligible. This form is a consolidation document for various business-related credits, ensuring taxpayers efficiently claim all applicable credits on one form. These credits can include incentives for investment, employment, research and development, and environmentally friendly practices.

Form 3800 is crucial for taxpayers who qualify for more than one business tax credit. The form is designed to aggregate the amounts from separate credit forms — such as the Work Opportunity Credit (Form 5884), Investment Credit (Form 3468), and Research Credit (Form 6765) — to determine the total amount of business credits that can be applied against their tax liability. This organized approach prevents the double claiming of credits across different forms and simplifies the process of applying multiple credits to reduce tax liabilities.
