2017 Tax Calendar

The 2017 tax filing season is quickly approaching and recent changes in legislation have resulted in adjustments to a few of the usual deadlines. Below you will find an overview of important dates for the different entities and the forms necessary for filing. Please keep these in mind as you begin to work with your Tax Preparer.

MARCH 2017

March 15

Partnerships. File a 2016 calendar year return (Form 1065). Provide each partner with a copy of Schedule K-1 (Form 1065), “Partner’s Share of Income, Deductions, Credits, etc.,” or a substitute Schedule K-1. If you want an automatic five-month extension of time to file the return and provide Schedule K-1 or a substitute Schedule K-1, file Form 7004. Then file Form 1065 by September 15.

S corporations. File a 2016 calendar year income tax return (Form 1120S) and pay any tax due. Provide each shareholder with a copy of Schedule K-1 (Form 1120S), “Shareholder’s Share of Income, Deductions, Credits, etc.,” or a substitute Schedule K-1. If you want an automatic six-month extension of time to file the return, file Form 7004 and deposit what you estimate you owe.

S corporation election. File Form 2553, “Election by a Small Business Corporation,” to choose to be treated as an S corporation beginning with calendar year 2017. If Form 2553 is filed late, S corporation treatment will begin with calendar year 2018.

Employers. For Social Security, Medicare, withheld income tax, and nonpayroll withholding, deposit the tax for payments in February if the monthly rule applies.

APRIL 2017

April 15

Corporations. File a 2016 calendar year income tax return (Form 1120) and pay any tax due. If you want an automatic six-month extension of time to file the return, file Form 7004 and deposit what you estimate you owe.

Individuals. File a 2016 income tax return. If you want an automatic six-month extension of time to file the return, file Form 4868, “Application for Automatic Extension of Time To File U.S. Individual Income Tax Return.” Then, file Form 1040, 1040A, or 1040EZ by October 15.

If you are not paying your 2017 income tax through withholding (or will not pay in enough tax during the year that way), pay the first installment of your 2017 estimated tax. Use Form 1040-ES.

Trust and Estate: File a 2016 calendar year income tax return (Form 1041) and pay any tax due. If you want an automatic six-month extension of time to file the return, file Form 7004 and deposit what you estimate you owe.

Employers. For Social Security, Medicare, withheld income tax, and nonpayroll withholding, deposit the tax for payments in March if the monthly rule applies.

Estimated Taxes for Business Owners

April 1 may be April Fool’s Day, but in 2017, April 18 might be considered April’s cruel day. Not only do you have to pay any income tax due for the previous year, you also may have to make an estimated tax payment for the current year. A poor estimate might result in either an underpayment that triggers a penalty or an overpayment that deprives you of valuable cash flow

Paying as an individual

Many business owners will pay estimated tax on the same IRS Form 1040-ES that individuals use for estimated tax. That’s the case if you run your business as an S corporation, a partnership, an LLC electing partnership taxation, or a sole proprietorship

Business owners filing estimated taxes on Form 1040-ES must pay in four installments. In 2017, this first payment is due April 18, the next payment is due only two months later, June 15, so there may be a cash crunch. Subsequent deadlines give you more time; payments are due on September 15 and January 15 of the following year. Use IRS Form 1040-ES for these payments.

You generally have to file estimated tax on Form 1040-ES if you owe $1,000 or more in tax when you file your return for the year. Thus, estimated tax won’t be a concern for businesses that will show a loss on their annual tax return.

Preventing penalties

You can avoid an underpayment penalty if all of your tax payments for the year—including withholding and tax credits—cover your ultimate tax bill, or at least go far enough that you come up short by less than $1,000. However, few business owners can accurately predict their 2016 tax obligation on April 18 or even June 15.

Thus, there are two safe harbors for those required to pay estimated tax. If you pay either (a) 90% of your current year’s tax obligation, or (b) 100% of the prior year’s tax, you won’t owe any penalty.

Example: Pam Owens has an interior design practice, set up as a sole proprietorship. When Pam prepares her tax return for 2015, it shows a $60,000 tax obligation for the year. Pam has no overpayment to put towards her 2016 tax obligation and she does not plan to have tax withheld during the year.

If Pam were confident of owing another $60,000 in tax this year, she could pay $54,000 (90% of $60,000) in estimated tax this year: $13,500 in each of four scheduled installments. That would avoid any risk of owing a penalty.

However, Pam does not know how much business income she’ll earn in 2016. If Pam’s income is much greater than in 2015, and she follows that $54,000 schedule, she could underpay her estimated tax and owe a penalty.

As an alternative, Pam could make four $15,000 estimated tax payments for 2016. That would total $60,000 in estimated tax—100% of her 2015 tax bill—and exempt Pam from a penalty.

However, if Pam’s adjusted gross income (AGI) in 2015 exceeded $150,000, she must pay more estimated tax under the safe harbor. Above that threshold, the safe harbor requires paying 110% of the prior year’s taxable income, rather than 100%. Thus, Pam decides to pay estimated tax this year in four $16,500 installments. This will bring Pam’s estimated tax total to $66,000—110% of the $60,000 in tax that she owed for 2015—so she won’t owe a penalty.

Note that this example assumes that Pam expects an increase in business this year, and a larger tax obligation. If there is some reason to expect a smaller tax obligation, Pam can reduce her obligation accordingly to meet the 90% safe harbor requirement.

Corporate calculation

The estimated tax rules for regular C corporations are similar but slightly different than those for individuals. Corporations must make installment payments on IRS Form 1120-W if the expected estimated tax for the year is $500 or more. Equal payments are due on the 15th day of the company’s 4th, 6th, 9th, and 12th months of the corporation’s tax year. A corporation with a tax year ending June 30, for example, would make payments by October 15, December 15, March 15, and June 15. (As is the case with individual estimated tax payments, the deadline is postponed to the next business day if the 15th is on a weekend or a legal holiday.)

The safe harbors for corporate estimated tax are both 100%. Thus, each installment should be at least 25% of the company’s current year income tax or 25% of the prior year’s income tax, whichever is smaller, in order to avoid an underpayment penalty.

Some businesses are seasonal, and estimated installment payments may be revised in keeping with two alternate methods. Our office can help you with seasonal estimated payments, if that’s an issue with your company.

A matter of interest

Some IRS penalties are fixed, such as the 10% penalty for early withdrawals from retirement accounts. That’s not the case with underpayments of estimated tax. For estimated tax infractions, the penalty is based on current interest rates, which are relatively low now. Still, the penalties can mount up, for large underpayments, and those penalties can be easily avoided by mooring in safe harbors.
