The New Section 199A Qualified Business Income Deductions
This is a subtitle for your new post
What is qualified business income deduction?
Section 199A qualified business income deduction is available from 2018 to 2025. Taxpayers may deduct 20% of Qualified Business Income from Partnerships, S Corporations, Sole Proprietorships (Schedule C's) and Real Estate Rental Activities (Schedule E's). This deduction was enacted to help pass-through entities who didn't receive the benefit of 21% C-corporation tax rate.
A sole proprietor with net Schedule C income of $100k can now take a tax deduction of $20k on his or her personal tax return, subject to income limitations discussed below.
Calculation of Section 199A deduction
The deduction is a function of the taxpayer's taxable income, net business income, and the wages paid and/or property owned by the business, and is generally based on the following:
·20% of taxpayer's qualified business income.
·The greater of 50% of the business's W-2 wages or 25% of the business's W-2 wages plus 2.5% of the original cost of all qualified property.
Full QBI deduction for Single taxpayers with taxable income below $157,500 and Married Couples with joint income below $315,000
For the single taxpayer with total taxable income below $157,500 ($315,000 for married filing jointly), the W-2 wages limit does not apply. Instead, the deduction will be limited to the lesser of 20% of the qualified business income or 20% of the total taxable income. It does not matter what kind of trade or business the taxpayer has.
Fully phased-out QBI deduction for Single taxpayer with taxable income exceeding $207,500 and Married Couples with joint income in excess of $415,000
Once the single taxpayer's taxable income exceeds $207,500 ($415,000 for MFJ), taxpayer's section 199A deduction is limited to the lesser of 20% of taxpayer's qualified business income or the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of depreciable property.
But a "specified service business" is no longer eligible for this deduction.
A specified service trade or business means any trade or business involving the performance of services in the fields of health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, including investing and investment management, trading, or dealing in securities, partnership interests, or commodities.
Partially phased-out QBI deduction for Single taxpayer with taxable income between $157,500 to $207,500 and Married Couples with joint income between $315k to $415k
When a single taxpayer's taxable income exceeds $157,500 ($315,000 for MFJ), the W-2 limitation is phased in. The deduction is limited to the lesser of 20% of taxpayer's qualified business income or the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of depreciable property. The qualified business income should be adjusted by an exclusion amount.
For example: An individual has taxable income of $177,500, QBI of $100,000. Base is $157,500. Top range is $207,500. The difference is $50,000. Amount over base is $20,000. Percentage that should be excluded from QBI: $20,000/$50,000=40%. So, the exclusion amount is $40,000. Adjusted QBI is $60,000. Deduction is $30,000 ($60k*20%).


If you own an unincorporated business, you likely pay at least three different federal taxes. In addition to federal income taxes, you must pay Social Security and Medicare taxes, also called the self-employment tax.
Self-employment taxes are not insubstantial. Indeed, many business owners pay more in self-employment taxes than in income tax. The self-employment tax consists of
- a 12.4 percent Social Security tax up to an annual income ceiling ($147,000 for 2022) and
- a 2.9 percent Medicare tax on all self-employment income.
These amount to a 15.3 percent tax, up to the $147,000 Social Security tax ceiling. If your self-employment income is more than $200,000 if you’re single or $250,000 if you’re married filing jointly, you must pay a 0.9 percent additional Medicare tax on self-employment income over the applicable threshold for a total 3.8 percent Medicare tax.
You pay the self-employment tax if you earn income from a business you own as a sole proprietor or single-member LLC, or co-own as a general partner in a partnership, an LLC member, or a partner in any other business entity taxed as a partnership. (There is an exemption for limited partners.)
You don’t pay self-employment tax on personal investment income or hobby income. For example, you don’t pay self-employment tax on profits you earn from selling stock, your home, or an occasional item on eBay.
The tax code bases your self-employment
tax on 92.35 percent of your net business income.
That means your business deductions are doubly valuable since they reduce both income
and self-employment taxes. In contrast, personal itemized deductions and “above-the-line”
adjustments to income don’t decrease your self-employment tax.
Some types of income are not subject to self-employment tax at all, including
- most rental income,
- most dividend and interest income,
- gain or loss from sales and dispositions of business property, and
- S corporation distributions to shareholders.
You calculate your self-employment taxes on IRS Form SE and pay them with your income taxes, including your quarterly estimated taxes.

Of course, the IRS is not likely to cut you a check for this money (although in the right circumstances, that will happen), but you’ll realize the cash when you pay less in taxes.
Here are six powerful business tax deduction strategies that you can easily understand and implement before the end of 2021.
1. Prepay Expenses Using the IRS Safe Harbor
You just have to thank the IRS for its tax-deduction safe harbors.
IRS regulations contain a safe-harbor rule that allows cash-basis taxpayers to prepay and deduct qualifying expenses up to 12 months in advance without challenge, adjustment, or change by the IRS.
Under this safe harbor, your 2021 prepayments cannot go into 2023. This makes sense, because you can prepay only 12 months of qualifying expenses under the safe-harbor rule.
For a cash-basis taxpayer, qualifying expenses include lease payments on business vehicles, rent payments on offices and machinery, and business and malpractice insurance premiums.
Example. You pay $3,000 a month in rent and would like a $36,000 deduction this year. So on Friday, December 31, 2021, you mail a rent check for $36,000 to cover all of your 2022 rent. Your landlord does not receive the payment in the mail until Tuesday, January 4, 2022. Here are the results:
- You deduct $36,000 in 2021 (the year you paid the money).
- The landlord reports taxable income of $36,000 in 2022 (the year he received the money).
You get what you want—the deduction this year.
The landlord gets what he wants—next year’s entire rent in advance, eliminating any collection problems while keeping the rent taxable in the year he expects it to be taxable.
2. Stop Billing Customers, Clients, and Patients
Here is one rock-solid, easy strategy to reduce your taxable income for this year: stop billing your customers, clients, and patients until after December 31, 2021. (We assume here that you or your corporation is on a cash basis and operates on the calendar year.)
Customers, clients, patients, and insurance companies generally don’t pay until billed. Not billing customers and patients is a time-tested tax-planning strategy that business owners have used successfully for years.
Example. Jim, a dentist, usually bills his patients and the insurance companies at the end of each week. This year, however, he sends no bills in December. Instead, he gathers up those bills and mails them the first week of January. Presto! He just postponed paying taxes on his December 2021 income by moving that income to 2022.
3. Buy Office Equipment
With bonus depreciation now at 100 percent along with increased limits for Section 179 expensing, buy your equipment or machinery and place it in service before December 31, and get a deduction for 100 percent of the cost in 2021.
Qualifying bonus depreciation and Section 179 purchases include new and used personal property such as machinery, equipment, computers, desks, chairs, and other furniture (and certain qualifying vehicles).
4. Use Your Credit Cards
If you are a single-member LLC or sole proprietor filing Schedule C for your business, the day you charge a purchase to your business or personal credit card is the day you deduct the expense. Therefore, as a Schedule C taxpayer, you should consider using your credit card for last-minute purchases of office supplies and other business necessities.
If you operate your business as a corporation, and if the corporation has a credit card in the corporate name, the same rule applies: the date of charge is the date of deduction for the corporation.
But if you operate your business as a corporation and you are the personal owner of the credit card, the corporation must reimburse you if you want the corporation to realize the tax deduction, and that happens on the date of reimbursement. Thus, submit your expense report and have your corporation make its reimbursements to you before midnight on December 31.
5. Don’t Assume You Are Taking Too Many Deductions
If your business deductions exceed your business income, you have a tax loss for the year. With a few modifications to the loss, tax law calls this a “net operating loss,” or NOL.
If you are just starting your business, you could very possibly have an NOL. You could have a loss year even with an ongoing, successful business.
You used to be able to carry back your NOL two years and get immediate tax refunds from prior years, but the Tax Cuts and Jobs Act (TCJA) eliminated this provision. Now, you can only carry your NOL forward, and it can only offset up to 80 percent of your taxable income in any one future year.
What does this all mean? You should never stop documenting your deductions, and you should always claim all your rightful deductions. We have spoken with far too many business owners, especially new owners, who don’t claim all their deductions when those deductions would produce a tax loss.
6. Deal with Your Qualified Improvement Property (QIP)
In the CARES Act, Congress finally fixed the qualified improvement property (QIP) error that it made when enacting the TCJA.
QIP is any improvement made by you to the interior portion of a building you own that is non-residential real property (think office buildings, retail stores, and shopping centers) if you place the improvement in service after the date you place the building in service.
The big deal with QIP is that it’s not considered real property that you depreciate over 39 years. QIP is 15-year property, eligible for immediate deduction using either 100 percent bonus depreciation or Section 179 expensing. To get the QIP deduction in 2021, you need to place the QIP in service on or before December 31, 2021.
