This document provides guidance on calculating the section 199A deduction for individuals. It discusses: 1) How to calculate the deduction for those with taxable income below the threshold amount, which is the lesser of 20% of qualified business income (QBI) or taxable income. 2) How to calculate the deduction for those with taxable income in the phase-in range above the threshold, which may be reduced based on a formula. 3) How to calculate the deduction for those with taxable income above the phase-in range, which is limited to 20% of QBI subject to W-2 wage and property limitations. It defines key terms like QBI and provides examples of how

1. 199A Deduction

2. Computation of the section 199A deduction for individuals with Taxable Income NOT exceeding
the threshold amount (Section 1.199A‐1(c) Treas. Regs.):
The Lesser of:
(i)
20% of the total QBI of taxpayer
(including individual’s share of QBI from an RPE and QBI attributable to an SSTB)
+
20% combined amount of qualified REIT and qualified PTP income
(including individual’s share of qualified REIT dividends and qualified PTP income from RPEs and qualified PTP income attributable to an
SSTB)
OR
(ii)
20% of [individual’s taxable income – net capital gain]

3. Computation of the section 199A deduction for individuals with taxable income DOES exceed the threshold
amount, and is within the phase‐in (phase‐in for married filing jointly $315,000 ‐ $415,000 ($100,000 phase‐
in buffer; $157,500 ‐ $207,500 for everyone else ($50,000 phase‐in buffer) :
If taxpayer’s TAXABLE INCOME is within the phase‐in range, and the W‐2 limitations (section 1.99A‐1(d)(2)(iv)(A)(2)
is less than the 20% of QBI calculated (section 1.199A‐1(d)(2)((iv)(A)(1)), then the General Rule is modified as such:
Combined Qualified Business Income=
{20% of the taxpayer’s QBI} less reduction amount as defined in section 1.199A‐1(b)(9)
(the excess amount multiplied by the ratio that the TAXABLE INCOME of
the individual for the taxable year in excess of the threshold amount)
Treas. Regs. Section 1.199A‐1(d)(2)(iv)(B)

4. Computation of the section 199A deduction for individuals with taxable income DOES exceed the threshold
amount, and exceeds the phase‐in (taxable income exceeds $415,000 for married filing jointly; exceeds
$207,500 for everyone else):
If taxpayer’s TAXABLE INCOME exceeds the phase‐in range, and the W‐2 limitations calculated under section 1.199A‐
1(d)(2)(iv)(A)(2) is GREATER THAN the amount determined under section 1.199‐1(d)(2)(iv)(A)(1), then:
Combined Qualified Business Income= 20% of QBI
[Note: none of the individual’s share of QBI, W‐2 wages, or UBAI of qualified property attributable to SSTBs may be
taken into account for purposes of determining the individual’s section 199A deduction ( Treas. Reg. section 1.199A‐
1(d)(2)(i)]
Treas. Regs. Section 1.199A‐1(d)(2)(iv)(B)
Please see Treas. Reg. Section 1.199A‐1(d)(4) for Examples.
‐ Example 4 – when taxable income exceeds threshold amount.
‐ Example 5 – when taxable income is within phase‐in range.

5. Qualified Business Income (QBI)
QBI is defined in Section 199A(c) as the “ordinary income – less ordinary deductions – you earn
from a sole proprietorship, S corporation, or partnership.
QBI does NOT include:
• any wages you earn as an employee
• Ex) independent K and employee doing the same job –self‐employment income of independent K is QBI, not the employees
wages
• Short‐term capital gain or loss;
• Long‐term capital gain or loss
• Dividend income
• Interest income any wages you earn as an employee
• For shareholder or partner of flow‐through, QBI does not include any wages or guaranteed payment received from
the business.
• QBI does not include income that is NOT “effectively connected with the conduct of a U.S. trade or business.”

6. EX)
• T owns 30% of S corporation that pays T $40,000 of wages and allocated T $80,000 of the income.
T’s QBI from the S corp is ONLY the $80,000 of income allocated to T via K‐1.
• $40,000 of wages T received from the S Corp are not included in QBI
Note: In summary, when beginning the process for determining the amount of the deduction (or QBI),
begin adding up the items of income and deductions on your K‐1 OTHER THAN the list provided on the
other slide to calculate your QBI.

7. QBI earned in a “qualified trade or business”
Section 199A(c) requires only that QBI be earned in a “qualified trade or business”
• Minimal guidance:
• PLR 201436001 (a pharmaceutical research and clinical testing company was a QTB because it did not “offer value
to customers primarily in the form of services … [or] individual expertise”)
• PLR 201717010 (a health care technology company providing laboratory reports was a QTB because the company
never offered a patient a “diagnosis or treatment recommendation,” but rather only issued the reports.)
• T.C. Memo 2012‐21 (In Owen v. Commissioner, the Tax Court concluded that a corporation’s principal asset did not
include the reputation or skill of one or more employees even though the court acknowledged that the success of
the corporation was attributable to its owners.)

8. Numerical Limitation‐
W‐2 limitations when Taxable Income exceeds thresholds

9. W‐2 Limitations
When taxpayer’s TAXABLE INCOME exceeds threshold amounts:
Taxpayers can only deduct 20% of QBI up to the LESSER OF…
(a) 20% of the QBI
or
(b) GREATER OF:
(i)50% of your allocable share of the “W‐2 wages” paid by the business
or
(ii)25% of your allocable share of the “unadjusted basis” immediately after acquisition of all “qualified property”
 For S corps‐ the allocable share is easy to calculate; all items of S corp are to be allocated on a pro‐rata, per‐share/per‐day basis (Section
1366 and 1377)
 W‐2 wages include: wages paid to an employee, including elective deferrals into 401(k) type vehicles or deferred compensation.
 W‐2 wages DO NOT include: payments to independent contractors or management fees (Section 199A(b)(4)(C) states that an amount is
not a W‐2 wage for these purposes unless it shows up on a payroll tax return.)
 This numerical limitation was added to prevent, for example, a lawyer from creating an S corp to receive his wages, which he would take a
deduction on as QBI

10. Exceptions to the W‐2 Wage Limitations
Section 199A(b)(3)(A): If a taxpayer’s TAXABLE INCOME (not AGI, not QBI) is less than the “threshold amount”
for the year, a taxpayer can ignore the two W‐2‐ based limitations.
For 2018, taxable income thresholds are $315,000 for married filing jointly and $157,500 for all other taxpayers.
Ex) A has QBI of $200,000 from S corp that paid 30,000 of W‐2 wages and no qualified property. A’s spouse has
$50,000 of W‐2 income, and A and B has interest income of $20,000. Total taxable income is $270,000.
Without the W‐2 Exception, A’s deduction would be limited to $15,000, the LESSER OF:
(a) 20% of QBI of $200,000, or $40,000, or
(b) The GREATER OF: (i) 50% of W‐2 wages of $30,000, or $15,000, or (ii) 25% of $30,000 plus 2.5% of $0, or $7,500.
However, when applying the W‐2 Exception, because “s taxable income is $270,000, less than the
$315,000 for married individuals, the two W‐2 limitations are disregarded and A can take the deduction equal to
20% of QBI, or $40,000.

11. Phase‐In of W‐2 Limitations
Section 199A(b)(3)(B) provides that once your taxable income exceeds the threshold amount ($315,000 if married filing
jointly; $157,500 for everyone else), the W‐2 limitations are phased‐in over the next $100,000 (for married filing jtly; $50,000
for everyone else).
Facts: A and B married, filing jtly. A earns $300,000 for S corp. A’s share of W‐2 wages paid by S corp is $40,000. No qualified
property. B earns $75,000 in W‐2 wages from her job. Taxable income is $375,000.
To calculate the Phase‐in of the W‐2 limitations, follow there three steps below:
Step 1: Calculate A’s deduction as if taxable income was less than $315,000.
‐ If QBI was $300,000, and if A’s taxable income did not exceed $315,000, A would be able to deduct $60,000.
Step 2: If the W‐2 limitations applied to the situation in Step 1, A’s $60,000 deduction would have been limited to the
GREATER OF: (i) 50% of $40,000 (A’s share of S corp’s W‐2 wages paid), or $20,000 or (ii) 25% of $40,000 plus 2.5% of $0, or
$10,000. So if the W‐2 limitations had applied (i.e. A and B jointly had taxable income exceeding $315,000), A would be
entitled to a $20,000 deduction. $40,000 ( $60,000 (deduction if less than $315K threshold) ‐ $20,000 (deduction if W‐2
limitations applied)) is the “excess amount” as defined in Section 199A(b)(3)(A)(ii).
Step 3: Once your taxable income exceeds $315,000, there is a $100,000 phase‐in range ($50,000 for all others). The “excess
amount” is reduced by how much A’s taxable income exceeds the $315,000 limit.
*see next page for example.

12. Phase‐In of W‐2 Limitations continued
Ex)
Taxable Income: $375,000
Less threshold: ($315,000)
Excess taxable income:$60,000
Meaning, A has gone $60,000 of the way through the $100,000 phase‐in range. So the $60,000 deduction (if w‐2 limitation
did not apply), should be reduced by 60%.
Step 4: A’s excess amount of $40,000 (a $60,000 deduction when a $20,00 W‐2 limitation would have otherwise applied) is
reduced by 60% because A’s taxable income exceeded the threshold and consumed 60% of the $100k phase‐in amount.
20% of ABI deduction: $60,000
Reduction in $40,000: ($24,000)
Final Deduction: $36,000

13. Substantive Limitation‐
Specified Service Trade or Business (SSTB)

14. QBI earned in a “qualified trade or business”
Section 199A(c) requires only that QBI be earned in a “qualified trade or business”
• Minimal guidance:
• PLR 201436001 (a pharmaceutical research and clinical testing company was a QTB because it did not “offer value
to customers primarily in the form of services … [or] individual expertise”)
• PLR 201717010 (a health care technology company providing laboratory reports was a QTB because the company
never offered a patient a “diagnosis or treatment recommendation,” but rather only issued the reports.)
• T.C. Memo 2012‐21 (In Owen v. Commissioner, the Tax Court concluded that a corporation’s principal asset did not
include the reputation or skill of one or more employees even though the court acknowledged that the success of
the corporation was attributable to its owners.)

15. Specified Service Trades or Businesses (SSTBs)
Section 199A(d)(1) states these are two types of businesses that are not eligible for the 20% QBI deduction:
(i) Anyone who is in the business of being an employee and
(ii) Any “specified service trade or business”
Section 199A(d)(2)(a) defines a “specified trade or business” in reference to Section 1202(e)(3)(A), which includes:
“Any trade or business involving the performance of services in the fields of health, law, engineering,
architecture, accounting, actuarial services, performing arts, consulting, athletics, financial services,
brokerage services, or any trade or business where the principal asset of such trade or business is the
reputation or skill of 1 or more of its employees.”
But the Section 199A modified the definition of “specified service businesses” found in section 1202 :
(i) Removing architects and engineers; and
(ii) The definition of disqualified businesses for purposes of Section 199A ignores 1202(e)(3)(B), and these types of
businesses are not disqualified businesses for purposes of Section 199A: banking, finance, insurance, leasing,
investing, farming, any business giving rise to depletion, any business operating a hotel or restaurant
(iii) And Section 199A(d)(2)(B) adds more businesses that do not qualify for the 20% QBI deduction: businesses of
investing, investment management, trading, or dealing in securities, partnership interests, or commodities.

16. SSTBs continued…
Treasury Regulations Section 1.199A‐5(b) defines SSTBs:
(1) Listed SSTBs. Any trade or business involving the performance of services in one or more of the following fields:
(i) Health as described in paragraph (b)(2)(ii) of this section;
(ii) Law as described in paragraph (b)(2)(iii) of this section;
(iii) Accounting as described in paragraph (b)(2)(iv) of this section;
(iv) Actuarial science as described in paragraph (b)(2)(v) of this section;
(v) Performing arts as described in paragraph (b)(2)(vi) of this section;
(vi) Consulting as described in paragraph (b)(2)(vii) of this section;
(vii) Athletics as described in paragraph (b)(2)(viii) of this section;
(viii) Financial services as described in paragraph (b)(2)(ix) of this section;
(ix) Brokerage services as described in paragraph (b)(2)(x) of this section;
(x) Investing and investment management as described in paragraph (b)(2)(xi) of this section;
(xi) Trading as described in paragraph (b)(2)(xii) of this section;
(xii) Dealing in securities (as defined in section 475(c)(2)), partnership interests, or commodities (as defined in section 475(e)(2) as described in paragraph
(b)(2)(xiii) of this section; or
(xiii) Any trade or business where the principal asset of such trade or business is the reputation or skill of one or more
of its employees or owners as defined in paragraph (b)(2)(xiv) of this section.

17. SSTBs continued…
(vii) Meaning of services performed in the field of consulting. For purposes of section 199A(d)(2) and paragraph (b) (1)(vi) of this section only, the performance
of services in the field of consulting means the provision of professional advice and counsel to clients to assist the client in achieving goals and solving problems.
Consulting includes providing advice and counsel regarding advocacy with the intention of influencing decisions made by a government or governmental agency
and all attempts to influence legislators and other government officials on behalf of a client by lobbyists and other similar professionals performing services in
their capacity as such. The performance of services in the field of consulting does not include the performance of services other than advice and counsel, such as
sales (or economically similar services) or the provision of training and educational courses. For purposes of the preceding sentence, the determination of
whether a person's services are sales or economically similar services will be based on all the facts and circumstances of that person's business. Such facts and
circumstances include, for example, the manner in which the taxpayer is compensated for the services provided. Performance of services in the field of consulting
does not include the performance of consulting services embedded in, or ancillary to, the sale of goods or performance of services on behalf of a trade or
business that is otherwise not an SSTB (such as typical services provided by a building contractor) if there is no separate payment for the consulting services.
Services within the fields of architecture and engineering are not treated as consulting services.

18. SSTBs continued…
(xiv) Meaning of trade or business where the principal asset of such trade or business is the reputation or skill of one or more employees
or owners. For purposes of section 199A(d)(2) and paragraph (b)(1)(xiii) of this section only, the term any trade or business where the
principal asset of such trade or business is the reputation or skill of one or more of its employees or owners means any trade or business that
consists of any of the following (or any combination thereof):
(A) A trade or business in which a person receives fees, compensation, or other income for endorsing products or services;
(B) A trade or business in which a person licenses or receives fees, compensation, or other income for the use of an individual's image,
likeness, name, signature, voice, trademark, or any other symbols associated with the individual's identity; or
(C) Receiving fees, compensation, or other income for appearing at an event or on radio, television, or another media format.
(D) For purposes of paragraphs (b)(2)(xiv)(A) through (C) of this section, the term fees, compensation, or other income includes the receipt of
a partnership interest and the corresponding distributive share of income, deduction, gain, or loss from the partnership, or the receipt of
stock of an S corporation and the corresponding income, deduction, gain, or loss from the S corporation stock.
* See 1.199A‐5(b)(3) for examples.

19. SSTBs Examples and the De minimus Rule
See 1.199A‐5(b)(3) for all examples.
(viii) Example 8. D is in the business of providing services that assist unrelated entities in making their personnel structures more efficient. D studies its client's
organization and structure and compares it to peers in its industry. D then makes recommendations and provides advice to its client regarding possible changes
in the client's personnel structure, including the use of temporary workers. D does not provide any temporary workers to its clients and D's compensation and
fees are not affected by whether D's clients used temporary workers. D is engaged in the performance of services in an SSTB in the field of consulting within the
meaning of section 199A(d)(2) or paragraphs (b)(1)(vi) and (b)(2)(vii) of this section.
(xi) Example 11. G is in the business of providing services to assist clients with their finances. G will study a particular client's financial situation, including, the
client's present income, savings, and investments, and anticipated future economic and financial needs. Based on this study, G will then assist the client in
making decisions and plans regarding the client's financial activities. Such financial planning includes the design of a personal budget to assist the client in
monitoring the client's financial situation, the adoption of investment strategies tailored to the client's needs, and other similar services. G is engaged in the
performance of services in an SSTB in the field of financial services within the meaning of section 199A(d)(2) or paragraphs (b)(1)(viii) and (b)(2)(ix) of this
section.
1.199A‐5(c)(1):
(c) Special rules—(1) De minimis rule—
(i) Gross receipts of $25 million or less. For a trade or business with gross receipts of $25 million or less for the taxable year, a trade or business is not an SSTB if
less than 10 percent of the gross receipts of the trade or business are attributable to the performance of services in a field described in paragraph (b) of this
section. For purposes of determining whether this 10 percent test is satisfied, the performance of any activity incident to the actual performance of services in
the field is considered the performance of services in that field.
(ii) Gross receipts of greater than $25 million. For a trade or business with gross receipts of greater than $25 million for the taxable year, the rules of paragraph
(c)(1)(i) of this section are applied by substituting “5 percent” for “10 percent” each place it appears.
