Tax and payroll compliance deadlines
Payroll tax deposits (for semi-weekly depositors)
Semi-weekly depositors—those who report more than $50,000 in payroll taxes during the lookback period of July 1, 2021 to June 30, 2022—must follow the schedule below:
|If payday for your employees is on…||Deposit employment taxes by…|
|Wednesday||The following Wednesday|
|Thursday||The following Wednesday|
|Friday||The following Wednesday|
|Saturday||The following Friday|
|Sunday||The following Friday|
|Monday||The following Friday|
|Tuesday||The following Friday|
However, if you accumulate $100,000 or more of tax liability in a single day, the IRS says you must deposit the amount by the following business day, regardless of whether you normally deposit on a semi-weekly or monthly basis (more on monthly deposits below).
To learn more about federal payroll tax deposits, read Publication 15.
Keep in mind that some state and local governments that collect payroll taxes will also expect their own deposits, and those deadlines may be different from the federal ones. For more information, contact your state and local tax agencies directly.

Form 1040 filing deadline
If you’re a calendar-year farmer or fisherman, you need to file Form 1040 and pay any tax due by March 1. However, if you paid your 2022 estimated tax payments by January 15, 2023, you have until Monday, April 17 to file.
If you’re a farmer or fisherman who operates on a fiscal tax year (starting after January 1), you have two options:
- Pay all your estimated tax by the 15th day after the end of your tax year
- File your return and pay all the taxes you owe by the 1st day of the 3rd month after the end of your tax year

March 15, 2023
Payroll tax deposits for monthly depositors
If your company follows the monthly payroll tax deposit schedule (meaning that you reported less than $50,000 in payroll taxes during the lookback period), then your tax deposit for February payrolls is due on March 15.
S corp (Form 1120-S) and partnership (Form 1065) tax returns due
If you own a partnership (or an LLC set up as a partnership), you’ll use Form 1065 to report the gains, losses, deductions, and credits of your operation. Keep in mind that each partner is responsible for paying their share of income from the business on their personal tax returns (Form 1040).
On top of the tax returns, S corps and partnerships must also submit a Schedule K-1 or Schedule K-3 that outlines the percentage of profits and losses assigned to each shareholder or partner in the business. You must submit these forms to the IRS by March 15, unless you apply for an extension.
You can request an automatic six-month extension on the deadline for these forms by submitting Form 7004 to the IRS by March 15. This extends your deadline to September 15, 2023. Keep in mind that if you take this option, you still need to pay your estimated taxes; otherwise, you could receive a penalty.
Forms 8804 and 8805 filing deadline for partnerships
If you own a partnership that operates on a calendar year, you have to file Form 8804 by March 15. Form 8804 is used to report the total liability for your partnership’s tax year.

Deadline for furnishing Forms 1095-C and 1095-B to employees

The due date for giving these forms to employees is March 2 (except for California employers, who needed to furnish these forms by January 31, 2023). If you send these forms by mail, make sure they’re postmarked by this date, since the IRS doesn’t offer extensions.

Form 1095-B includes information about the health benefits you offer and your employee’s enrollment status. Form 1094-B is the transmittal form that must accompany Form 1095-B.
To learn more about filing Forms 1095-C and 1095-B, you can read the IRS instructions here.
