There are two keys to avoiding tax penalties—having a solid year-round accounting system and being on time. While this article is primarily about the latter, I’d be remiss if I didn’t emphasize that creating and following good, clean accounting and bookkeeping practices regularly. Establishing a process early on makes a world of difference allowing you to be strategic about your taxes rather than just keeping as many receipts as you can fit in a shoebox and dropping them off at your local CPA’s office come tax season.

How you handle income taxEither way, building a simple but structured annual calendar for both your business and personal tax returns can help you stay organized and avoid paying more than you have to.

The expensive consequences of missing an income tax deadline

Simply put, if you do not pay your tax liability by your original return due date, you’ll get hit with three penalties at once:

  1. Late payment penalty: typically ½  of 1% of your unpaid income taxes, per month
  2. Interest on taxes owed: the federal short-term rate plus 3% with interest compounding daily
  3. Late filing penalty: usually 5% of the unpaid income taxes for each month an income tax return is late. This penalty starts to accrue the day after the income tax filing due date and will not exceed 25% of the remaining tax liability.

Although somewhat counterintuitive, this is still the case even if you’ve extended your filing due date. You’re expected to estimate your tax liability and pay what you can in good faith. So in addition to your business’s extension deadline, you’ll also still need to mark your calendar for the original due date. You’ll determine these dates based on your type of business entity and fiscal year.

If you haven’t already heard, the income tax deadlines look a little different in 2017

Those who have filed business tax returns before will notice what’s been causing a bit of a buzz in the CPA universe. Starting in 2017, partnerships, who used to submit tax returns by mid- April (at the same time as individuals filed their returns), will now file in mid-March with other businesses. Conversely, C corporations who used to submit tax returns by mid- March will now file in mid- April.

September 15, 2017

  • The final deadline for extended Partnership, C Corporation and S corporation to file tax returns.

October 16, 2017

  • The final deadline for extended individual returns.

These dates are based on the use of the calendar year (starting January 1 and ending December 31) as a business’s fiscal year. If your business does not use the calendar year, consult this article to learn which ways an alternative fiscal year can affect your business taxes, and how you can adjust your tax return calendar.

Why did they switch the partnership and C Corporation due dates? And why does this help?

This change to the partnership tax return deadline ultimate helps the partners of that company the most. Because partnerships must take care of their filing responsibilities in March, there’s a whole extra month left for them to distribute information their partners may need for their individual returns in April. In a partnership, every partner must receive a Schedule K-1 disclosing their earnings for the year—similar to a W-2 for an employee. In turn, the partner must claim those earnings as income or lack thereof as losses on their tax return.

There’s still time to save time and money on business taxes, with the right strategy

It’s probably not shocking that most of the questions we get from small business owners revolve around saving money on taxes. And fortunately for them there are many ways small businesses can lower their income tax liability.
