Document:
In general, IRC § 199A provides that a non-corporate taxpayer may, subject to certain adjustments and limitations, deduct 20% of the taxpayer’s qualified business income (“QBI”) with respect to each qualified trade or business, plus; 20% of the aggregate amount of qualified cooperative dividends, qualified real estate investment trust dividends and qualified publicly traded partnership income of the taxpayer for the tax year.
(2) the sum of 25% of the W-2 wages paid with respect to the qualified trade or business, plus 2.5% of the unadjusted basis, immediately after acquisition, of all “qualified property”[i] of the qualified trade or business (the “Wage and Capital Limit”).
If a taxpayer’s taxable income for the year does not exceed the applicable “income threshold amount,” the QBI Limitation is inapplicable. The “income threshold amount” is $315,000 for married individuals filing jointly and $157,500 for other individuals. Both amounts are subject to inflation adjustments in future years.
For married individuals filing jointly, the QBI Limitation is phased in on a sliding scale over the next $100,000 of taxable income above the “income threshold amount.” For other taxpayers, the phase in occurs over the next $50,000 above the “income threshold amount.” Thus, the limitation fully applies when taxable income is over $415,000 for married individuals filing jointly, and $207,500 for other individuals.
IRC § 199A provides that a “qualified trade or business” means any trade or business other than a “specified service business” or the trade or business of performing services as an employee.
Not all service businesses made the list. While the list of service businesses is broad, Congress specifically excluded architecture and engineering services from the list.
For owners of a “specified service business,” if their taxable income exceeds the “income threshold amount,” the IRC § 199A deduction is totally lost without application of the QBI Limitation. By way of example, a partner in an accounting firm who has less than $315,000 of taxable income (married filing jointly) will be entitled to an IRC § 199A deduction, subject to the QBI Limitation, while another partner in the same accounting firm who is married filing jointly and has over $415,000 of taxable income will be excluded entirely from the deduction (without the application of the QBI Limitation).
After the TCJA was adopted this past December, the tax media was replete with discussions about how “specified service businesses” could plan around a total loss of the IRC § 199A deduction due to the “income threshold amount.” The plan, commonly referred to as a “crack and pack” plan, involves spinning off the administrative and non-professional service functions to a new pass-through entity owned by the same persons who own the service business. The new entity would charge the old entity for its work, thereby reducing the old entity’s owners’ income to a negligible amount. Like magic, in the minds of several commentators, the IRC § 199A deduction would be preserved to a significant degree.
Not so fast! Many commentators and tax practitioners, including us, believed that the Service would include anti-abuse safeguards in any regulations issued under IRC § 199A in order to prevent this type of plan around strategy. We were correct.
For businesses with “specified service business” income and income from other sources, they will not be considered a “specified service business” for purposes of IRC § 199A if: (i) for businesses with gross receipts of $25 million or less, less than ten (10) percent of gross receipts is generated from the specified service; and (ii) for businesses with gross receipts over $25 million, less than five (5) percent of gross receipts is generated from the specified service.
Stay tuned! We will report further on the new proposed regulations in a future blog post.
[i] For these purposes, “qualified property” means tangible, depreciable property which is held by and available for use in the qualified trade or business at the close of the tax year, which is used at any point during the tax year in the production of QBI, and the depreciable period for which has not ended before the close of the tax year. The “depreciable period” is the later of 10 years from the original placed-in-service date or the last day of the last full year of the applicable recovery period under IRC § 168.
