1099 consulting income taxes: what you owe on expert call and advisory income

1099 consulting income taxes work the same way whether or not a Form 1099-NEC shows up: in the US, money you earn from expert calls, advisory work or side consulting is taxable, and the IRS gig economy tax center says you must report it even when it is not reported on a form such as a 1099-NEC. If you work for yourself, you also owe self-employment tax of 15.3% on top of income tax once your net earnings reach $400. This post walks through the forms, the deadlines and one worked example.

This is general information. A tax professional should check your own situation before you file.

1. The income is taxable whether or not a 1099 arrives

A Form 1099-NEC is a report the payer sends to the IRS and to you. It does not create the tax, and its absence does not remove it. The IRS gig economy tax center lists "creative or professional services" and freelance work among the kinds of work you must report, including income "not reported on an information return form" such as a 1099-NEC, 1099-MISC or 1099-K.

So count every payment yourself, including small ones. Your bank statement is the record that matters. The 1099s are a cross-check.

2. Payers now send a 1099-NEC only from $2,000, so expect fewer of them

The IRS page on whether a payer must file a Form 1099 gives the nonemployee compensation threshold by year:

• For payments made before 2026, the threshold is $600.
• For payments made in 2026, it is $2,000.
• For payments made after 2026, it is adjusted for inflation, and the page points to Publication 1099 for the amount.

The 2026 instructions for Forms 1099-MISC and 1099-NEC say the same thing: report nonemployee compensation of $2,000 or more, a threshold that "may be adjusted for inflation beginning in calendar year 2027." Payers must furnish the form to you by January 31.

In practice, a network that paid you $1,500 across three calls in 2026 has no duty to send you a 1099-NEC for that year. You still report the $1,500. (The IRS gets fewer forms. It does not get less curious.)

Short version: in 2026, the 1099 threshold went up and your reporting duty did not change.

3. Foreign expert networks may send nothing at all

Some networks are based outside the US and do not issue 1099s to US experts. Our post on AlphaSights expert pay covers one network that says so in its own FAQ. The IRS rule in section 1 still applies: the payment is income, and you report it.

Keep a simple log for these payers, since nobody will summarize the year for you: the date, the payer, the amount in dollars and the payment method. If you were paid in another currency, write down the dollar amount that landed in your account on the day it arrived.

4. Report the income on Schedule C and the self-employment tax on Schedule SE

If you take calls or advise as an independent contractor, the IRS self-employment tax page says you generally use Schedule C (Form 1040) to figure your net earnings and Schedule SE (Form 1040) to figure the self-employment tax.

Schedule C is for income or loss from a business or profession you run as a sole proprietor. The IRS says an activity counts as a business if your primary purpose is income or profit and you take part "with continuity and regularity." Regular expert calls fit that description more easily than a single call you took once. If you are unsure which side of that line you are on, that is the first question to put to a tax professional.

Schedule C is where your business expenses come off. What is left (your net profit) is the number that drives self-employment tax.

5. Self-employment tax is 15.3% of 92.35% of your net profit

Self-employment tax is the Social Security and Medicare tax that an employer would normally split with you. The IRS self-employment tax page gives the rate as 15.3%: 12.4% for Social Security and 2.9% for Medicare. You owe it if your net earnings from self-employment are $400 or more, and the Schedule SE instructions use the same $400 test for filing the schedule.

Two details from the IRS self-employment tax topic change the arithmetic:

• The tax applies to 92.35% of your net earnings from self-employment, not the full amount.
• You can deduct one-half of the self-employment tax when you figure adjusted gross income. That lowers your income tax, not the self-employment tax itself.

The Social Security part stops at an annual cap that changes each year. The 2026 Form 1040-ES puts it at $184,500 for 2026, and the IRS self-employment tax page explains that the cap applies to your combined wages and net self-employment earnings. So if your salary plus side income passes $184,500, the 12.4% part stops on the amount above it, while the 2.9% Medicare part keeps going. The same IRS topic says an additional Medicare tax applies to self-employment income above $200,000 for single filers ($250,000 married filing jointly, $125,000 married filing separately).

6. Here is the arithmetic for one made-up year

Here is a made-up example. Renata is a procurement director at a regional hospital system who takes expert calls in the evenings, usually from a spare bedroom with a whiteboard that still says "Q3 GPO renewals." In 2026 she earns $10,500 from side work:

She uses the spare bedroom only for this work, so she takes the home office deduction under the IRS simplified option: $5 per square foot, up to 300 square feet. Her office is 100 square feet, so the deduction is $500.

Our arithmetic from there:

1. Net profit on Schedule C: $10,500 minus $500 is $10,000.
2. Amount subject to self-employment tax: 92.35% of $10,000 is $9,235.
3. Self-employment tax: 15.3% of $9,235 is about $1,413.
4. Deduction for half of it: about $706, which reduces the income she pays income tax on.

Her salary plus the $10,000 stays well under the $184,500 Social Security cap, so the full 15.3% applies. Income tax on the $10,000 comes on top, at whatever rate her salary already puts her in.

7. Pay as you go: quarterly estimates or more withholding from your paycheck

The IRS estimated taxes page says you generally must pay estimated tax if you expect to owe $1,000 or more when you file, and that individuals use Form 1040-ES to figure it. The 2026 Form 1040-ES lists the 2026 due dates:

The IRS estimated tax FAQ shows the periods behind those dates are uneven: the second payment covers only April and May. If you are reading this in late 2026, the January 15, 2027 payment is the one still ahead. The 1040-ES also says you can skip it if you file your 2026 return by February 1, 2027 and pay the full balance with it.

The same form describes the safe harbor. In most cases you do not have to pay estimated tax if your withholding and refundable credits cover the smaller of 90% of your 2026 tax or 100% of the tax on your 2025 return (if that return covered all 12 months). If your 2025 adjusted gross income was over $150,000 ($75,000 married filing separately), substitute 110% for 100%.

If you also have a salary, use the easier route. The IRS estimated taxes page says wage earners can avoid estimated payments by asking their employer to withhold more, using a new Form W-4. In Renata's case, one W-4 change in January beats four calendar reminders.

8. Home office is the deduction to check first

The IRS simplified option page sets the rules for the easiest home office method: the space must be used "exclusively" and "on a regular basis" for business, and the deduction is $5 per square foot up to 300 square feet (a $1,500 maximum by our arithmetic). The same page says employees can no longer claim a home office deduction as employees, so the deduction belongs to your side business, not your day job.

A kitchen table that also hosts dinner does not meet the exclusive-use test. A spare room used only for calls may. For other expenses, ask your tax professional what counts for your kind of work, and keep the receipts either way.

Before your next payment lands

Rates set before taxes can look better than they are. The consulting rate calculator builds taxes into an hourly rate, and consulting as a side hustle covers employer policies and finding the first clients. For what one large network pays, see how much GLG pays.

On Instant Expert, a buyer invites you to a specific paid call or a written or voice answer and sets the amount up front. You receive the full amount offered, and you can reply with a higher price. You can claim your profile, or see open paid requests on the request board.
