1099: How Much Should I Save for Taxes per Deposit?

Quick Answer: Move a fixed percentage of every 1099 deposit into a separate savings account the day it lands. Work the percentage out as your self-employment tax factor (about 14.13% of profit) plus your marginal federal income tax bracket, scaled down by the share of each deposit that goes to business expenses. For many freelancers in the 12% bracket that lands near 20% of gross deposits; in the 22% bracket it is closer to 28%, before any state tax.

Nobody withholds tax from a 1099 payment, so the question is not what you owe in April but how much of today's deposit is already spoken for. The workable answer is a set-aside rate: one percentage, applied to every client payment, parked in a separate account, then checked against real bank statements after the first and second quarters.

Why is there no single right percentage?

You will see "save 25 to 30%" repeated everywhere, and for some people it is about right. For others it is thousands of dollars too much or too little. Three things move the number:

• Your expenses. Tax falls on profit, not on deposits. A photographer who spends 35 cents of every dollar on gear and travel owes far less per deposit than a consultant whose costs are a laptop and a phone plan.
• Your bracket. The 2026 federal brackets the IRS published put a single filer's taxable income above $50,400 into the 22% bracket and above $105,700 into 24%. Other household income, such as a spouse's salary, pushes your freelance dollars higher.
• Self-employment tax. This part is close to flat. The IRS self-employment tax page sets the rate at 15.3% (12.4% Social Security, 2.9% Medicare), charged on 92.35% of net earnings. The 2026 Form 1040-ES caps the Social Security portion at $184,500 of combined wages and self-employment earnings, and an extra 0.9% Medicare tax applies above certain income thresholds.

State income tax, if your state has one, sits on top. Look up your state's rate separately and add it to the rate you build below.

Building your set-aside rate

Do this once in a small Settings tab. Each cell holds one piece of the rate so you can change it later without rewriting formulas.

The (1-B2/2) piece reflects that you can deduct the employer-equivalent half of self-employment tax when working out adjusted gross income, so a slice of each profit dollar escapes income tax. At the 22% bracket, B3 becomes 0.3458.

That is a rate per dollar of profit. Deposits are not profit, so the tracker in the next section scales it by your expense ratio. With 20% of revenue going to expenses, a 12%-bracket filer moves about 20.2% of each deposit; a 22%-bracket filer moves about 27.7%.

How do I track it deposit by deposit?

Add a second tab called Deposits. One row per client payment, copied from your business checking statement.

Column I is the "1099 paycheck": what you can actually spend from a payment once the tax slice is gone. Freelancers who budget from column I instead of column B stop being surprised in April.

Worked row. A $4,000 client payment arrives on March 3. Expenses so far this year are 20% of deposits, and your Settings rate is 0.2528. Column F gives 4000 × 0.80 × 0.2528 = $809.02. You move $809.02 to the tax account and treat $3,190.98 as your pay.

Do the transfer the same day. The tracker only works if the balance in column H matches the real balance of the savings account; a gap between them means a transfer was skipped.

When does the money leave the tax account?

Four times a year. The 2026 Form 1040-ES lists the installment dates as April 15, June 15 and September 15, 2026, with the fourth on January 15, 2027. Enter each payment in column G on the row where you pay it, and column H drops by that amount.

The IRS estimated tax page sets the general requirement: individuals who expect to owe $1,000 or more when they file generally need to pay during the year, and the penalty can apply even if you end up with a refund. It also describes the safe harbor based on 90% of this year's tax or 100% of last year's, and the 2026 Form 1040-ES raises that 100% to 110% if your 2025 adjusted gross income was over $150,000. If you use the prior-year figure, your installments are fixed in advance and the tracker's job becomes making sure the account can cover each one.

Truing the rate up after Q1 and Q2

The marginal-bracket rate is a quick, deliberately cautious guess. Two checkpoints turn it into a real number.

1. After March statements arrive. Total deposits and business expenses for January through March. Recompute the expense ratio from actual figures rather than the one you guessed in January.
2. After June statements arrive. Annualize: double the six-month profit for a rough full-year figure (or use your own seasonal pattern if the year is lumpy). Run that through the full liability calculation in our self-employed tax calculator spreadsheet to get a projected year's tax.
3. Set the new rate. Subtract what you have already saved from the projected liability, and divide by the profit you expect for the rest of the year.

Example. By June 30 your statements show $46,000 deposited and $6,000 of expenses, a $40,000 half-year profit. At the 0.2528 rate you have saved $10,112.71. Annualized profit is $80,000. Self-employment tax on that is $11,303.64. Subtract half of it ($5,651.82) and the $16,100 single standard deduction, and taxable income is $58,248.18, which reaches the 22% bracket. Income tax on it is $1,240 + $4,560 + $1,726.60 = $7,526.60, for a projected total of $18,830.24. You still need $8,717.53 from roughly $40,000 of second-half profit: about 21.8% of profit. That is lower than the 34.6% the 22% marginal rate would suggest, because most of your income still sits in the lower brackets. Put 0.218 in Settings!B5 for the second half.

Pulling six months of transactions out of PDF statements is the tedious part. If your bank only gives you PDFs, QuickBankConvert turns each statement into spreadsheet rows you can paste under the Deposits tab, so the true-up takes minutes of sorting rather than an evening of retyping.

So how much will I owe on my 1099 income?

At year end, the Deposits tab answers that directly. Total profit goes into the full calculation; the result is your tax for the year. Compare it with column G's total: the difference is what you pay with the return (or get back). The tax account balance in column H should be at least that difference. If it is larger, the extra is yours, or a head start on next year's first installment.

If you also hold a W-2 job, the withholding on your paychecks covers part of the bill. Our W-2 plus 1099 calculator guide shows how the two interact, including the shared Social Security wage base.

What this routine does not handle

• It ignores credits and most deductions beyond the standard deduction and the half-SE adjustment, so it usually overestimates. That error is the safe direction.
• It assumes a single filer in the example. Joint filers should use the joint brackets from the same IRS release.
• It is a savings habit, not tax advice. A tax professional can tell you whether other deductions or an entity choice change your numbers.
