To budget on 1099 income, treat the tax set-aside as a bill that comes out of every payment first, base your monthly spending on your slowest recent month, and put the quarterly tax dates on a calendar. Nobody withholds anything from a 1099 payment, so the whole amount that lands in your account is not yours to spend.
This guide is from the Monthly team. It is general education, not tax or personalized financial advice. Tax rules vary by situation, so confirm yours with the IRS pages linked below or a tax professional. Every dollar figure in the examples is invented.
What changes when you’re paid on a 1099
On a W-2 job, your employer withholds income tax and the employee share of Social Security and Medicare before the check arrives. As an independent contractor, none of that happens. The client pays the full invoice, and you are responsible for the taxes yourself.
Two taxes matter here. The first is regular income tax on your net profit. The second is self-employment tax. The IRS says the self-employment tax rate is 15.3 percent, made up of 12.4 percent for Social Security and 2.9 percent for Medicare, and that you owe it if your net earnings from self-employment were $400 or more. That rate applies to net earnings, meaning income after business expenses, and the exact calculation is on Schedule SE, so a preparer or the IRS instructions will show you how to compute it.
A related point about the form itself: the reporting threshold for Form 1099-NEC rose to $2,000 for payments made after December 31, 2025, according to the IRS FAQ on Form 1099-NEC. That determines when a client must send you the form, not when income is taxable. Small jobs that never generate a 1099 still count as income.
The budgeting problem: lumpy money and a tax bill
Contract income has two properties that a salary doesn’t. It arrives in irregular amounts at irregular times, and a slice of it belongs to the government later. A budget that ignores either will feel fine until a bill is due.
The solution is a three-account habit, even if it is only three labels in your head:
- Tax holding account. A separate savings account. Every time a payment arrives, a fixed percentage moves here before anything else.
- Business or operating money. Software, equipment, a co-working day: the costs of earning.
- Your pay. What remains is the amount you can plan your personal budget around.
This guide focuses on the third part, which is where a monthly budget does its work. But the other two must exist first, or the third is overstated.
Step 1: Pick a placeholder tax rate and move it immediately
You don’t need the perfect percentage on day one. You need a defensible one, and then a habit of moving it the day the money lands.
The honest answer is that it depends on your total income, deductions, filing status and state. Some people begin with a round conservative figure such as 25 or 30 percent of each payment and then refine it. For illustration only, the example below uses 25 percent. It is not a recommendation or a tax rate. Check last year’s return, or ask a preparer, for a better estimate.
Here is the pattern with invented amounts:
| Payment received | 25% set aside | Left for the month |
|---|---|---|
| Client A invoice: $2,200 | $550 | $1,650 |
| Client B invoice: $1,400 | $350 | $1,050 |
| Client C invoice: $600 | $150 | $450 |
| Total | $1,100 | $3,150 |
The month brought $4,200 in payments. A quarter went to the tax account right away, leaving $3,150 as the person’s pay. Everything below is built on $3,150, not on $4,200.
Step 2: Build the budget on your slowest recent month
Irregular income means irregular months. The last three months for the same person:
| Month | Payments received | After 25% set-aside |
|---|---|---|
| July | $5,100 | $3,825 |
| August | $2,300 | $1,725 |
| September | $4,200 | $3,150 |
If the plan assumed the average, about $2,900 after set-aside, August would have broken it. The safer approach is to build fixed commitments around the lowest month, $1,725, and treat anything above it as a deliberate extra. If the person’s fixed expenses total $1,500, they are covered in even a slow month, with $225 to spare.
Step 3: Pay yourself a steady amount
One of the best habits in contract work is to pay yourself a regular amount from the lumpy income, like a salary. You hold the lump sums in an operating account and move the same amount to your personal account each month.
In the example, the person could choose a $2,200 monthly personal paycheck. In July, $5,100 less the tax set-aside leaves $3,825. After the $2,200 draw, $1,625 stays in the buffer. August produces only $1,725, so the draw comes from the buffer built in July. September’s $3,150 refills it.
This is the point of the buffer: it turns uneven receipts into an even personal budget. The size of it depends on how irregular your work is. A person with one steady client needs less than someone who gets paid by many clients on 60-day terms.
Step 4: Find the real free money from the steady draw
With a steady monthly draw, the budget becomes an ordinary one. Take the draw, subtract fixed expenses and a weekend reserve, and see what is left.
| Item | Amount |
|---|---|
| Monthly personal draw (after tax set-aside) | $2,200 |
| Rent | $950 |
| Utilities and internet | $140 |
| Phone | $55 |
| Health insurance premium | $260 |
| Groceries (planned amount) | $320 |
| Software and other business costs | $75 |
| Total fixed expenses | $1,800 |
| Weekend reserve | $120 |
| Real free money | $280 |
The arithmetic is $2,200 minus $1,800 minus $120, which leaves $280. Notice what is on the list: health insurance, which an employer may have partly covered, and business software. Contractors often forget costs that used to be handled by an employer. Add them to the fixed list so the free-money figure isn’t flattering.

Step 5: Put the quarterly tax dates on a calendar
Because no employer withholds, the IRS generally expects you to pay as you go through estimated tax. The IRS says that individuals, including sole proprietors, generally must make estimated payments if they expect to owe $1,000 or more when they file, per its estimated taxes page. The agency’s estimated tax overview lists the dates for the 2026 tax year:
| Payment period (2026 income) | Due date |
|---|---|
| January 1 to March 31 | April 15, 2026 |
| April 1 to May 31 | June 15, 2026 |
| June 1 to August 31 | September 15, 2026 |
| September 1 to December 31 | January 15, 2027 |
If a due date falls on a weekend or legal holiday, a payment made the next business day is on time. You may also skip the January payment if you file your 2026 return by February 1, 2027 and pay the full balance with it.
Because today is mid-October, the next date on that list is January 15, 2027. If your tax account has been collecting a percentage of each payment, this is the moment to check that the balance is on track for the next payment. The IRS also notes you can pay in smaller, more frequent amounts as long as enough has been paid by the end of each quarter.
To limit the penalty for paying too little, the IRS says you are generally covered if you paid the smaller of 90 percent of this year’s tax or 100 percent of last year’s tax, as described on its estimated taxes page. Special rules apply to higher-income taxpayers, so check with a preparer if that might be you.
Add each deadline to your calendar a week ahead, and put the expected payment in your monthly plan as a fixed expense in the month it falls due. That way a quarterly payment never shows up as a surprise.
Step 6: Treat each payment as that month’s income
Because 1099 work doesn’t have a predictable rate, avoid building the plan on an assumed monthly figure. In Monthly you would enter the payments you actually received as that month’s income, put the tax set-aside as a fixed expense, and let the free-money calculation rebuild each time. The app doesn’t read invoices or connect to any account, so the numbers are the ones you enter.
If a client pays late, the calculation shows the shortfall in the month it applies, and the buffer is there to cover it. When the payment arrives, enter it, and the number updates. This is the same process described in the monthly budget guide, repeated each month.
Step 7: Track the money you’re owed
Contractors spend a lot of time waiting to be paid. An invoice sent in September and due in November is real money but not available money. Keep a list of open invoices with expected dates, and don’t count them in a month’s income until they arrive. Monthly includes a place for money owed to you, which keeps the expected receipts visible without mixing them into spendable income.
Common mistakes on 1099 income
Spending the full deposit. The amount that arrives is gross of taxes you will owe. Move the set-aside first.
Budgeting off the best month. One big invoice makes the plan look rich. Build on the slow months.
Forgetting costs an employer used to cover. Health insurance, software, equipment and retirement contributions now come from you.
Treating small jobs as invisible. Without a 1099, income is still income. Record it.
Skipping the quarterly dates. Paying too little by a due date can bring a penalty even if you are owed a refund at filing, according to the IRS. Calendar the dates.
Using one account for everything. Mixed money makes it impossible to see what is yours.
A checklist before the next invoice
- Is there a separate account for the tax set-aside?
- Have you chosen a placeholder percentage, ideally confirmed against last year’s return or by a preparer?
- Is the monthly budget built on your slowest recent month?
- Are you paying yourself a regular draw?
- Are the estimated tax dates on your calendar, with the next one noted?
- Are costs like health insurance and software in the fixed list?
- Do you have a list of open invoices, kept separate from received income?
Budgeting on 1099 income comes down to two disciplines: set the tax money aside first, and plan from your slowest month. Both can be done in an afternoon, and both make the free-money figure honest. Open Monthly, enter this month’s payments with your tax set-aside as a fixed expense, and see what your freelance month really leaves you.
