Every small business, except partnerships, needs to handle federal business tax filing each year.
Partnerships are a bit different. They file an information return (Form 1065) because their income passes through to the partners, who then report it on their personal tax returns.
Here’s how small business tax filing works based on your business structure:
- Sole proprietorships: Use Form 1040 along with Schedule C. This is part of the small business tax process where income is reported on your personal return.
- Partnerships and S Corps: Partners and individual shareholders file Form 1040 with Schedule E. S Corporations also need to file Form 1120-S. S Corps don’t pay federal business taxes themselves; instead, shareholders report the income on their personal returns.
- C Corporations: File Form 1120 and are subject to the US corporate tax rate, also known as the federal business tax rate, which is 21%
For
LLCs, the filing requirements depend on their setup. They could be treated as partnerships, corporations or like a sole proprietorship, affecting how small business tax is handled.
Sole proprietors and individual partners in a partnership need to pay
self-employment tax for Social Security and Medicare. To report this, they should include Schedule SE with their Form 1040. The self-employment tax rate is 15.3%. This breaks down to 12.4% for Social Security and 2.9% for Medicare.
Keep in mind that small business owners need to pay
estimated taxes to avoid penalties. Since taxes aren’t withheld from your income like they are for regular employees, you must calculate and pay taxes every quarter. This covers both income tax and self-employment tax. You can use Form 1040-ES to figure out how much you owe and when to pay.
