96860 Honolulu 2025 Business Tax Deadline for Federal Income Tax Returns for the 2024 tax year depends on the type of business you’re operating. For example, calendar year partnerships must file Form 1065 by March 17, 2025, but calendar year corporations have until April 15, 2025, file Form 1120.
Other business tax deadlines exist for estimated tax payments, payroll taxes, W-2 forms, information returns, and other returns and tax payments.
Key Honolulu 2025 Business Tax Deadlines to Note:
If a federal tax deadline falls on a weekend or legal holiday, the due date is automatically extended to the next business day.
C Corporations, S Corporations, Partnerships, and Sole Proprietorships all have specific federal income tax return due dates. In 2025, sole proprietors and C corporations operating on a calendar year must file by April 15, while S corporations and partnerships have a March 17 deadline.
C Corporations are generally required to make estimated tax payments if they expect to owe $500 or more when their return is filed. The deadlines are spaced throughout the year and depend on the corporation's fiscal calendar.
S Corporations, Partnerships, and Sole Proprietors may need to make estimated tax payments if they expect to owe $1,000 or more.
Employers are responsible for withholding payroll taxes and must comply with deposit and reporting deadlines. Businesses must also provide W-2s to employees and file them with the Social Security Administration, as well as distribute and file 1099 forms for payments to nonemployees, by January 31, 2025.
2025 Tax Return Deadline for Honolulu Regular Corporations
For regular corporations such as C Corporations their federal income tax return (Form 1120) for the 2024 tax year is due on April 15, 2025.
If your corporation operates on a fiscal year basis - for example a July 1 to June 30 tax year - then Form 1120 is generally due by the 15th day of the fourth month after the end of its tax year.
There’s an exception to the normal due date for certain fiscal-year corporate filers, so a corporation with a fiscal year ending June 30 must file Form 1120 by the 15th day of the third month after the end of its tax year - by September 15.
Your corporation can get an extra six months to file Form 1120 by requesting a business tax filing extension using Form 7004 (seven months for corporations with tax years ending June 30). For example, a calendar year corporation can get an extension to October 15, 2025, for its 2024 federal income tax return. Form 7004 must be filed, and any tax due for the tax year must be paid, by the original due date of Form 1120.
2025 Tax Return Deadline for Honolulu S Corporations
An S Corporation must file Form 1120-S by the 15th day of the third month after the end of its tax year. For calendar year S Corporations, that translates to a March 17, 2025, due date for 2024 tax year returns.
Since S Corporations are pass-through entities such as shareholders report the business’s income and losses on their personal tax returns, they must also provide a Schedule K-1 to each shareholder by the date Form 1120-S is due and all Schedule K-1s must also be sent to the IRS. The Schedule K-1 identifies each shareholder’s share of the S Corporation’s income, deductions, credits, and other items.
S Corporations can also request an automatic six-month filing by submitting Form 7004 by the original due date. That will push the due date for 2024 tax year returns to September 15, 2025, for calendar year S Corporations. However, even though S Corporations are pass-through entities, the business itself can owe certain taxes if it was previously a C Corporation or engaged in a tax-free reorganization with a C Corporation. These taxes must still be paid by the original filing deadline.
