The flat 21% federal income tax rate for C corporations under the Tax Cuts and Jobs Act (TCJA) has been great news for these entities and their owners. But some fundamental tax truths for C corporations largely remain the same:

C corporations are subject to double taxation. Double taxation occurs when corporate income is taxed once at the corporate level and again at the shareholder level as dividends are paid out. The cost of double taxation, however, is now generally less because of the 21% corporate rate.

And double taxation isn’t a problem when a C corporation needs to retain all its earnings to finance growth and capital investments. Because all the earnings stay “inside” the corporation, no dividends are paid to shareholders, and, therefore, there’s no double taxation.

Double taxation also isn’t an issue when a C corporation’s taxable income levels are low. This can often be achieved by paying reasonable salaries and bonuses to shareholder-employees and providing them with tax-favored fringe benefits (deductible by the corporation and tax-free to the recipient shareholder-employees).

C corporation status isn’t generally advisable for ventures with appreciating assets or certain depreciable assets. If assets such as real estate are eventually sold for substantial gains, it may be impossible to extract the profits from the corporation without being subject to double taxation. In contrast, if appreciating assets are held by a pass-through entity (such as an S corporation, partnership or limited liability company treated as a partnership for tax purposes), gains on such sales will be taxed only once, at the owner level.

But assets held by a C corporation don’t necessarily have to appreciate in value for double taxation to occur. Depreciation lowers the tax basis of the property, so a taxable gain results whenever the sale price exceeds the depreciated basis. In effect, appreciation can be caused by depreciation when depreciable assets hold their value.

To avoid this double-taxation issue, you might consider using a pass-through entity to lease to your C corporation appreciating assets or depreciable assets that will hold their value.

C corporation status isn’t generally advisable for ventures that will incur ongoing tax losses. When a venture is set up as a C corporation, losses aren’t passed through to the owners (the shareholders) like they would be in a pass-through entity. Instead, they create corporate net operating losses (NOLs) that can be carried over to future tax years and then used to offset any corporate taxable income.

This was already a potential downside of C corporations, because it can take many years for a start-up to be profitable. Now, under the TCJA, NOLs that arise in tax years beginning after 2017 can’t offset more than 80% of taxable income in the NOL carryover year. So it may take even longer to fully absorb tax losses.

To avoid interest and penalties, you must make sufficient federal income tax payments long before your April filing deadline through withholding, estimated tax payments, or a combination of the two. The third 2018 estimated tax payment deadline for individuals is September 17.

If you don’t have an employer withholding tax from your pay, you likely need to make estimated tax payments. But even if you do have withholding, you might need to pay estimated tax. It can be necessary if you have more than a nominal amount of income from sources such as self-employment, interest, dividends, alimony, rent, prizes, awards or the sales of assets.

A two-prong test

Generally, you must pay estimated tax for 2018 if both of these statements apply:

You expect to owe at least $1,000 in tax after subtracting tax withholding and credits, and
You expect withholding and credits to be less than the smaller of 90% of your tax for 2018 or 100% of the tax on your 2017 return — 110% if your 2017 adjusted gross income was more than $150,000 ($75,000 for married couples filing separately).

If you’re a sole proprietor, partner or S corporation shareholder, you generally have to make estimated tax payments if you expect to owe $1,000 or more in tax when you file your return.

Quarterly payments

Estimated tax payments are spaced through the year into four periods or due dates. Generally, the due dates are April 15, June 15 and September 15 of the tax year and January 15 of the next year, unless the date falls on a weekend or holiday (hence the September 17 deadline this year).

Estimated tax is calculated by factoring in expected gross income, taxable income, deductions and credits for the year. The easiest way to pay estimated tax is electronically through the Electronic Federal Tax Payment System. You can also pay estimated tax by check or money order using the Estimated Tax Payment Voucher or by credit or debit card.

Confirming withholding

If you determine you don’t need to make estimated tax payments for 2018, it’s a good idea to confirm that the appropriate amount is being withheld from your paycheck. To reflect changes under the Tax Cuts and Jobs Act (TCJA), the IRS updated the tables that indicate how much employers should withhold from their employees’ pay, generally reducing the amount withheld.

The new tables might cause some taxpayers to not have enough withheld to pay their ultimate tax liabilities under the TCJA. The IRS has updated its withholding calculator (available at irs.gov) to assist taxpayers in reviewing their situations.

Avoiding penalties

Keep in mind that, if you underpaid estimated taxes in earlier quarters, you generally can’t avoid penalties by making larger estimated payments in later quarters. But if you also have withholding, you may be able to avoid penalties by having the estimated tax shortfall withheld.
