When Is My Company’s 2020 Tax Return Due?

Filing your taxes on time is a lot easier when (1) you know when the returns are due and (2) you have your financial records and information ready for your tax return preparer (even if that person is you!)

It’s that time of year again – the holiday season – and that means the end of the tax year, with tax returns due in the not-too-distant future!  Filing your taxes on time is a lot easier when (1) you know when the returns are due and (2) you have your financial records and information ready for your tax return preparer (even if that person is you!)

When are 2020 business taxes due in 2021?

To start, what is the type of entity you own or operate?  Is it a partnership, S corporation, C corporation – or are you a sole proprietorship?  Also, if you work at, or are responsible for, a non-profit or charity we’re providing that information as well.  Once you’ve determined the entity type, you can identify what your deadline is for filing business taxes using the table below. 

But what if I’m not ready to file my return – may the business get an extension?  Generally, the short answer is, “Yes”!  The table also provides the extended filing due dates for each type of entity.  If you elect to take advantage of the extension, you will also need to consider both weekends and federal holidays, as federal tax returns that fall on these days shift to the next business day.
