Tax software for W2 and 1099 income and the best way to file taxes with both

What the best tax software for W2 and 1099 costs

Every major brand can file a W-2 and a 1099 on one return. The difference is which tier you are pushed into the moment you have business expenses to deduct. This table prices one return: a W-2, a 1099-NEC with expenses, and one state.

TurboTax and TaxAct prices are from each company's own product page, read in October 2026. Both discount early in the season and charge more near April. FreeTaxUSA and Cash App Taxes are cheaper than we are and we would rather say so. They suit someone who already knows which expenses belong on a Schedule C. If the side income is new, the deductions you miss usually cost more than the software, which is the case the worked example below makes. The full grid is on our tax software comparison.

How to file taxes with both W2 and 1099

You file one return. There is no separate return for the side income and no separate deadline.

Both forms can go in as files. If you would rather not retype boxes, upload the W2 and file taxes from a picture of it, then add each 1099 the same way.

1. Wages go on Form 1040, line 1a. Box 1 of the W-2 is the income, box 2 is the federal tax already paid for you.
2. 1099 income goes on Schedule C. You report the gross amount from each 1099-NEC or 1099-K, plus anything paid without a form, then subtract the costs of earning it.
3. Schedule SE adds self-employment tax. It is 15.3 percent of 92.35 percent of the Schedule C profit. Half of it comes back as an adjustment to income.
4. The QBI deduction takes up to 20 percent of the side-business profit off your taxable income.
5. Everything meets on page 2. Income tax on the combined total plus self-employment tax, minus the withholding from the W-2 and any estimated payments. The difference is your refund or balance due.

A return is required once net self-employment earnings reach $400, even if no 1099 arrived. Clients send a 1099-NEC at $600 for payments made in 2025 and at $2,000 for payments made during 2026, so more side income will go unreported on a form from here on. It is still taxable. Our 1099 tax filing page covers the forms in detail.

W2 and 1099 in the same year on real numbers

A single filer for 2026 earns $62,000 at a day job and $18,000 on a 1099-NEC from weekend work. The employer withheld $5,260, exactly right for the salary alone. The first column claims $4,200 of expenses for mileage, a phone share, software and supplies. The second claims none, which is what happens when the 1099 total is typed in and the business screens are skipped.

Two things stand out. The $4,200 of expenses was worth $1,280, more than fourteen times the price of the software. And the side income was taxed at roughly a third even after expenses, because it sits on top of the salary in the 22 percent bracket and carries self-employment tax as well. If you want your own figures before you file, the 1099 tax calculator takes W-2 and 1099 income together.

Why you owe when the day job withheld enough

Your employer withholds as if the salary were your only income. Nothing is withheld from a 1099, so the whole tax on the side profit arrives as a bill. In the example above that bill is $3,757, and because it is over $1,000 and withholding covered less than 90 percent of the total, an underpayment penalty can be added unless last year's tax was fully covered.

There are two ways to stop it happening again, and the first is easier than most people expect:

• Raise your withholding at the day job. Put an extra amount per paycheck on Step 4(c) of Form W-4. For the filer above, about $145 on each of 26 paychecks covers the side income. The IRS treats withholding as paid evenly through the year no matter when it came out of your pay, so a change made in the autumn still counts for the earlier quarters. The tax withholding calculator works out the figure.
• Pay quarterly estimated tax. Four payments, due April 15, June 15 and September 15, 2026 and January 15, 2027. Unlike withholding, each one only counts from the day you pay it. The quarterly tax calculator sizes each payment.

You are safe from the penalty if withholding plus estimates reach 90 percent of this year's tax or 100 percent of last year's, rising to 110 percent if last year's adjusted gross income was over $150,000.

Best TurboTax for W2 and 1099 and what it costs

TurboTax Premium is the version that handles a W-2 together with a 1099 that has expenses against it. It lists at $139 for the federal return, with each state charged on top. TurboTax Deluxe at $79 lets you enter 1099-NEC income, but the complete Schedule C with its expense categories is in Premium, so a side business with any real costs ends up there. The Free Edition does not cover Schedule C at all.

That is the upgrade prompt people hit halfway through: the W-2 goes in on a cheaper tier, then the 1099 screen asks for Premium. We priced every tier in TurboTax pricing and compared the two paid tiers in TurboTax Deluxe vs Premium. TaxFile has no tier decision for this return. A W-2 plus 1099 income is the $89 Self-Employed plan, state included, from the first screen.

High earners and the Social Security wage base

Social Security tax stops at a wage base, $184,500 for 2026, and your W-2 wages count toward it first. If the job already used up most of the base, only the remainder of your side profit carries the 12.4 percent Social Security part of self-employment tax. The 2.9 percent Medicare part has no cap.

Take $170,000 of wages and $30,000 of side profit. Net earnings from self-employment are $27,705. Only $14,500 of that is still under the wage base, so self-employment tax is $2,601 rather than the $4,239 you would get by applying 15.3 percent to the lot. That $1,638 is lost whenever the W-2 and the Schedule C are worked out separately, on a spreadsheet or in two different tools. Filing both in one return is what makes Schedule SE see the wages.

Which 1099 forms fit with a W-2 here

"1099" covers several different forms, and they do not all go to the same place.

TaxFile also does not prepare rental income on Schedule E, prior-year returns or amended returns. If your second income is driving or delivery, the gig worker taxes page deals with platform fees and mileage, and self-employed tax deductions lists what a side business can claim.
