The IRS released the official 2026 inflation adjustments for tax brackets, standard deductions, retirement contributions, and business deductions. If you are a freelancer, independent contractor, or gig worker, these numbers are the foundation for every quarterly payment, every Schedule C filing, and every budget decision you make this year. Using last year's figures will produce an incorrect tax bill or an unnecessary overpayment.

Why 2026 Numbers Are Different

The IRS adjusts tax figures annually to prevent bracket creep. When inflation pushes wages higher, fixed tax brackets would silently increase your effective rate without new legislation. The chained CPI adjustment keeps the tax code roughly neutral in real dollars. For freelancers, the adjustment changes the exact dollars you owe on every quarterly estimated payment.

The One Big Beautiful Bill Act also amended several 2026 thresholds after the initial inflation release, creating a two-layer adjustment: baseline CPI indexing plus statutory changes from the new law. That means some 2026 figures are higher than a pure inflation forecast would predict, while others changed for policy reasons unrelated to price growth.

Standard Deduction and Tax Brackets

The standard deduction for 2026 rises to reflect inflation. If you do not itemize business expenses, these are your baseline shelter from tax.

• Standard deduction (single): $16,100
• Standard deduction (married filing jointly): $32,200
• Standard deduction (head of household): $24,150

The marginal tax brackets remain at the TCJA rates made permanent by the One Big Beautiful Bill: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The phase-out thresholds for the standard deduction do not apply because the deduction itself is fixed by filing status; itemizers face a separate SALT cap and Pease limitation that the OBBBA modified.

Self-Employment Tax and Social Security Wage Base

Freelancers pay both the employer and employee share of FICA through the self-employment tax. That is 15.3% on 92.35% of net earnings, which works out to an effective rate of 14.13% on all net self-employment income. Only the first $184,500 of earnings is subject to Social Security tax in 2026; the Medicare portion has no wage cap.

Original calculation: a freelance developer with $90,000 net self-employment income owes $12,657 in SE tax. The calculation is $90,000 × 92.35% = $83,115 of taxable earnings. Social Security tax is $83,115 × 12.4% = $10,306. Medicare tax is $83,115 × 2.9% = $2,410. Total is $12,716. You can deduct half of that, $6,358, from your adjusted gross income when calculating federal income tax.

Retirement Contribution Limits

The SEP IRA limit climbs to $66,000 for 2026, or 25% of net self-employment income, whichever is lower. The SIMPLE IRA contribution limit rises to $17,000 for workers under 50, with a $4,000 catch-up for those 50 and older. The 401(k) elective deferral limit rises to $25,000, with a $8,500 catch-up for those 50 and older. These increases matter for freelancers who want to shelter significant income from current-year tax.

Business Expense and Mileage Rates

The standard mileage rate splits into two halves in 2026. From January through June, the rate is 72.5 cents per mile. From July through December, the rate rises to 76 cents per mile. The increase reflects higher fuel and maintenance costs. If you drive for client meetings, between job sites, or to the airport for contract work, the deduction is automatic and does not require itemizing.

Actual calculation: a freelance consultant driving 8,000 business miles in the first half of 2026 and 6,000 miles in the second half deducts $5,800 + $4,560 = $10,360 in mileage. At a 24% marginal tax rate, that reduces federal tax by $2,486. If you use actual expenses instead of the standard rate, you must track every gallon of gas, repair bill, and insurance payment.

What Freelancers Should Do Now

The 2026 tax year changes are already in effect. If you pay quarterly estimated taxes, recalculate your payment amounts using the new standard deduction and mileage rates. If you contribute to a SEP IRA, confirm that your contributions do not exceed the $66,000 cap. If you itemize, verify that your SALT estimate reflects the new $40,000 cap from the One Big Beautiful Bill.

1. Update your quarterly estimated payment worksheet with the 2026 figures.
2. Switch to the 76-cent mileage rate for any business miles driven after June 30, 2026.
3. Review your SEP IRA contribution plan before year-end.
