The jump from a W-2 paycheck to 1099 income feels like freedom — and tax-wise, it genuinely is, once you understand the trade you just made. You gain access to an entire category of business deductions that employees can no longer touch, but you also inherit taxes and paperwork your old employer used to handle quietly in the background.
What W-2 employees lose access to
Since recent federal tax law changes, unreimbursed employee business expenses — the home office, mileage between job sites, professional subscriptions, a portion of your cell phone bill — are simply no longer deductible for W-2 workers, even if your employer never reimburses them. That door is closed regardless of how legitimate the expense is.
What opens up as a 1099 contractor
- Home office deduction — see our full guide
- Business mileage — using either the standard rate or actual expenses
- Health insurance premiums — often deductible above the line, detailed in Health Insurance Premiums Deduction for the Self-Employed
- Retirement contributions — with dramatically higher limits than a typical employer 401(k), covered in SEP IRA vs. Solo 401(k)
- Software subscriptions, equipment, professional development, and a portion of internet and phone bills
The trade-off: self-employment tax
As a W-2 employee, your employer paid half of your Social Security and Medicare taxes automatically. As a 1099 contractor, you are both the employer and the employee — which means you owe the full 15.3% self-employment tax yourself, on top of income tax. Our article Self-Employment Tax Explained walks through exactly how that number is calculated, and how half of it becomes an above-the-line deduction that softens the blow.
No more automatic withholding
A W-2 employer withholds tax from every paycheck automatically. A 1099 payer typically does not. That means the responsibility to set aside money and pay the IRS quarterly shifts entirely to you — miss it, and penalties stack up even if you pay in full by April.

Frequently asked questions
Can I be both a W-2 employee and a 1099 contractor in the same year?
Yes — many people hold a W-2 job and freelance on the side. In that case, only the income and expenses tied to the 1099 side of your work qualify for business deductions.
Which usually results in a lower overall tax bill?
It depends heavily on your expenses and income level. Business deductions can meaningfully lower taxable income, but the added 15.3% self-employment tax works in the opposite direction — run the numbers for your specific situation rather than assuming either is automatically cheaper.
Do I need to form an LLC to claim these deductions?
No. A sole proprietor filing a Schedule C can claim the same core business deductions as an LLC; entity structure affects liability protection and some advanced tax strategies, not eligibility for these basic write-offs.
