Every U.S. business owes a recurring set of required business reports and filings, and the specific mix depends on entity type, whether the business has employees, and whether it pays outside contractors or vendors. For most active companies the list runs to five categories: a state annual (or biennial) report, a federal income tax return, quarterly payroll returns if there are employees, 1099s for qualifying payments to contractors and other non-employees, and, for nonprofits, an annual 990-series return. Each filing has its own deadline and its own penalty structure, and none of them wait for you to catch up on the others.
State Annual Report and Franchise Tax
Every state requires registered business entities — corporations, LLCs, and partnerships — to file a periodic update with the Secretary of State or equivalent office. Some states run on an annual cycle, others biennial. The report keeps public records current: business address, names of directors, officers or managing members, and the registered agent’s identity and address. Fees typically fall between $20 and $500 depending on entity type and state.
This filing is separate from any tax return. Late reports usually trigger penalty fees that accrue monthly, and if the report stays unfiled long enough the state can administratively dissolve or forfeit the entity. Once that happens, the business loses its legal authority to operate, enter contracts, or maintain lawsuits until it is reinstated.
A number of states also charge a franchise tax or privilege tax for the right to exist as a legal entity in the state. This is not an income tax. A company with zero revenue still owes it, and a company registered in several states may owe franchise tax in each one. Some states calculate it on net worth, some on revenue, some as a flat fee. Dormant entities are still on the hook.
Federal Income Tax Returns by Entity Type
The IRS requires every business to file an annual federal income tax return, but the form depends on how the entity is classified for tax purposes.
- A C-Corporation files Form 1120 and pays income tax at the entity level.1Internal Revenue Service. About Form 1120, U.S. Corporation Income Tax Return
- An S-Corporation files Form 1120-S, an informational return; income and losses flow through to shareholders’ personal returns.2Internal Revenue Service. S Corporations
- Partnerships, including multi-member LLCs taxed as partnerships, file Form 1065 and issue each partner a Schedule K-1.3Internal Revenue Service. Instructions for Form 1065
- Single-member LLCs and sole proprietorships report business income directly on Schedule C of the owner’s personal Form 1040. There is no separate entity-level return.
Deadlines
Calendar-year partnerships and S-Corporations file by March 15. Calendar-year C-Corporations file by April 15, the 15th day of the fourth month after the tax year ends.4Internal Revenue Service. Starting or Ending a Business These returns must be filed even if the business had no revenue or operated at a loss.
Late-Filing Penalties
C-Corporations face a failure-to-file penalty of 5% of unpaid tax per month, capped at 25%. Partnerships and S-Corporations are penalized per owner: for returns due in 2025 or later, the penalty is $245 per partner or shareholder for each month the return is late, up to 12 months. A five-partner LLC that files three months late owes $3,675 in penalties regardless of whether any tax is due.5Internal Revenue Service. Notice 746 – Information About Your Notice, Penalty and Interest
Estimated Tax Payments
C-Corporations that expect to owe $500 or more in tax must pay quarterly estimates. For calendar-year filers those payments are due April 15, June 15, September 15, and December 15. The IRS charges an underpayment penalty based on the shortfall, the length of the underpayment, and the quarterly interest rate the IRS publishes.6Internal Revenue Service. Underpayment of Estimated Tax by Corporations Penalty
Payroll and Employment Tax Filings
Once a business has employees, a separate set of federal filings kicks in.
Form 941, Filed Quarterly
Employers file Form 941 each quarter to report wages paid, federal income tax withheld, and the employer and employee shares of Social Security and Medicare taxes. Deadlines are April 30, July 31, October 31, and January 31 of the following year.7Internal Revenue Service. Employment Tax Due Dates If you deposited all taxes for the quarter on time, you get an additional 10 calendar days to file the return itself.
Payroll Tax Deposits
Between quarterly filings, employers deposit withheld taxes on either a monthly or semiweekly schedule, depending on payroll size. Late-deposit penalties are graduated: 2% if the deposit is 1 to 5 days late, 5% if 6 to 15 days late, and 10% beyond 15 days. After the IRS issues a formal demand notice, the penalty rises to 15%.
W-2s to Employees and the SSA
Employers must furnish each employee a Form W-2 by January 31 following the end of the tax year and file copies with the Social Security Administration by the same date. This deadline is firm and does not follow the extended dates that apply to some other information returns.
1099s for Contractors, Landlords, and Attorneys
Businesses that pay independent contractors, landlords, attorneys, or other non-employees above certain thresholds must report those payments to the IRS using 1099-series forms. Starting with the 2026 tax year, the reporting threshold for many of these payments rose from $600 to $2,000.8Internal Revenue Service. Publication 1099 – Guide to Information Returns (2026)
Form 1099-NEC
Form 1099-NEC reports nonemployee compensation paid to independent contractors, freelancers, and other service providers. For the 2026 tax year, you file a 1099-NEC for any individual or non-corporate entity you paid $2,000 or more during the year. The recipient copy and the IRS copy are both due January 31 of the following year.
Form 1099-MISC
Form 1099-MISC covers rent, gross proceeds paid to attorneys, royalties, and several other payment categories. Rent paid to a non-corporate landlord and gross proceeds paid to attorneys both use the $2,000 threshold for 2026. Royalties have a much lower threshold of $10. Payments to C-Corporations and S-Corporations are generally exempt from 1099-MISC reporting, except for payments to attorneys and medical providers. Recipient copies are due by January 31, and the IRS copies by March 31. Payments processed through credit card companies or third-party payment platforms get reported by the processor on Form 1099-K, so you should not duplicate them on a 1099-MISC.
Penalties for Missing 1099s
The IRS charges per-form penalties on late or missing information returns. For forms due in 2026:
- Filed within 30 days of the deadline: $60 per form
- Filed 31 days late through August 1: $130 per form
- Filed after August 1 or not at all: $340 per form
- Intentional disregard: $680 per form, with no maximum cap
These add up per form, not per batch. A business that skips 50 required 1099s past August 1 is looking at $17,000. Small businesses (average annual gross receipts of $5 million or less) get lower maximum caps, but the per-form amounts are the same.9Internal Revenue Service. Information Return Penalties
Beneficial Ownership Reporting: Where It Stands Now
The Corporate Transparency Act originally required most U.S.-formed companies to file a Beneficial Ownership Information Report with FinCEN. That requirement has been removed for domestic entities. In March 2025 FinCEN issued an interim final rule exempting all entities created in the United States, along with their beneficial owners and company applicants, from BOI reporting. FinCEN has stated it will not enforce BOI-related penalties or fines against U.S. citizens or domestic companies.10Financial Crimes Enforcement Network. FinCEN Removes Beneficial Ownership Reporting Requirements for U.S. Companies and U.S. Persons, Sets New Deadlines for Foreign Companies
The requirement now applies only to foreign-formed entities registered to do business in a U.S. state or tribal jurisdiction. Foreign entities registered before March 26, 2025 had a filing deadline of April 25, 2025. Foreign entities registered on or after that date must file within 30 calendar days of receiving notice that their registration is effective.11Financial Crimes Enforcement Network. Beneficial Ownership Information Reporting Domestic owners no longer have a filing obligation under the CTA, though future rulemaking could change that.
Annual 990 Filings for Tax-Exempt Organizations
Organizations holding federal tax-exempt status under Section 501(a) file an annual return from the Form 990 series. The specific form depends on size:12Internal Revenue Service. Publication 4839 – Annual Form 990 Filing Requirements for Tax-Exempt Organizations
- Form 990-N (e-Postcard): organizations with annual gross receipts normally $50,000 or less.
- Form 990-EZ: gross receipts under $200,000 and total assets under $500,000.
- Form 990: gross receipts of $200,000 or more, or total assets of $500,000 or more.
Churches, government entities, and organizations described in Section 501(c)(1) that are organized under an Act of Congress are exempt from filing.13Internal Revenue Service. Annual Exempt Organization Return – Who Must File Private foundations file Form 990-PF instead of the standard 990.
The consequence for missing this filing is severe. An organization that fails to file its required 990-series return for three consecutive years loses its tax-exempt status automatically, as of the due date of the third missed return. No warning letter comes first. Reinstatement requires filing a new application for exemption, and donations received during the revocation period may not be tax-deductible to the donors.
Reporting a Change in Responsible Party or Address
When the person responsible for a business’s tax matters changes — a new officer, member, or point of contact on the Employer Identification Number — the entity must notify the IRS within 60 days by filing Form 8822-B. The same form reports a change in business address. Skipping this filing routes IRS notices to the wrong person and delays responses to audits and penalty notices.14Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party – Business
Building a Compliance Calendar
The real risk for most businesses is not any single report but the sheer number of deadlines running in parallel. A company with employees and contractors might owe W-2s and 1099-NECs by January 31, a partnership return by March 15, quarterly payroll tax returns four times a year, estimated tax payments four times a year, and a state annual report on yet another date. Each filing has its own penalty structure. Mapping every applicable deadline onto one calendar at the start of the year — with the form number, the due date, and the responsible person for each — is the most reliable way to keep a missed filing from turning into an expensive surprise.
