When Are Taxes Due? Filing and Extension Dates for 2023

Late tax payments are especially frustrating because they often could have been avoided with a little bit of planning. To stay ahead of the Internal Revenue Service, jot down the deadlines for filing the necessary paperwork on your calendar.

Tax Day

Tax season technically runs from January to April, but the big day is typically April 15. If that time frame happens to fall on a weekend or holiday, it will be moved to the following Monday.

Because of the observance of Emancipation Day on April 17, and the fact that April 15 is a Saturday this year, tax day will be observed on April 18, 2023. For those filing as an individual or a business, or as a C corporation, this is the deadline.

It is important to remember that the tax filing deadline varies from business entity to business entity, and from fiscal year to fiscal year, if your company is not using the calendar year as its fiscal year.

When is the deadline for filing your taxes?

The due dates for payments remain the same, regardless of whether or not you are granted a grace period. There is a 5% late filing penalty, but only 0.5% per month for late payments. Whether or not your small business can afford to pay its taxes in full, getting them in on time always pays off.

If you are mailing your return, it will be considered "on time" as long as it is properly addressed, has sufficient postage, and is mailed before the close of business on the filing deadline. If you can't get your return in the mail by the deadline, you can e-file it at any time before midnight on that day.

If you are self-employed, your company will likely make four tax payments throughout the year instead of one large payment in the spring. You can think of estimated tax payments as a down payment on your future income and self-employment tax liabilities (Medicare and Social Security). The due dates for these 2023 payments are April 18, June 15, September 15, and January 15 (2024).

We'll put you in touch with a dedicated team of bookkeepers and a tax team who will provide you with year-round tax advice and file your taxes on your behalf. You will have a tax planning session to ensure you are better prepared for next year. We'll relieve you of both headaches—bookkeeping and taxes—for good.

When are tax extensions for 2023 due?

The deadline for requesting a tax extension is April 15. On April 18, 2023, you can still submit your request for a tax extension if you are an individual. Similarly, businesses have until March 15 and April 18 respectively to file for extensions (for S corporations and partnerships, respectively).

Every 2022 tax due date is listed below. If you have an LLC or a S corporation, we also have specific guides for when your tax payments are due.

If you are self-employed, today is the deadline to set up a solo 401k.

When can I start filing taxes for 2023?

In most years, the IRS begins accepting returns in the middle to latter part of January. The earlier you start working with a tax expert, the less work they will have to do for you later. Demand for their services increases as the deadline approaches, and they have fewer resources to take on new customers.

Exactly when will I receive my tax return?

The IRS promises that most refunds will be issued within 21 days of receiving a tax return. That is not something the IRS would ever guarantee. However, in most cases, you can anticipate receiving your tax refund within three to four weeks of submitting your return. 

The IRS Where's My Refund tool allows you to check the status of your refund in as little as five minutes.

Making a Payment on Your Taxes After the Due Date

If you pay your taxes after the deadline, a penalty will be added to the total. This amounts to an extra 0.5% per month on top of the original tax bill (up to a maximum of 25% of the original tax bill) if you don't pay up. Each month that taxes are not paid after they are due, a 5% penalty is added. In other words, filing on time will save you money in penalties even if you cannot afford to pay your tax bill in full.
