Estimated payments ensure that you pay a large percentage of the estimated tax liability during the year rather than in one payment when filing the tax return.
Business taxes due dates
For corporations with a calendar year-end, the deadline to send your 1120 form to the IRS is April 15, 2024. However, the Form 1120 due date for corporations with a fiscal year-end is the 15th day of the fourth month after the end of the corporation’s tax year.
A fiscal year-end is any business that ends its year on any day other than December 31. Note that a corporation with a fiscal tax year ending June 30 must file by September 15. For S-corps, multimember LLCs, and partnerships, the business tax filing deadline is March 15, 2024.
Here are the key business tax dates you need to know:
- January 31, 2024 – W-2 form distribution deadline: Send W-2s to employees before the end of January for the previous tax year.
- January 31, 2024 – 1099 form distribution deadline: Date to send the 1099 forms like 1099-MISC and 1099-NEC to recipients. This is also the deadline to file 1099-NEC forms with the IRS.
