Introduction
Being self-employed doesn't stop you from claiming the standard deduction. But it doesn't replace your business expense deductions either. The two apply at different stages of a U.S. federal return.
The standard deduction and 1099 terminology below belong to U.S. federal tax returns. The ATO's rules for business and personal deductions govern your Australian return. Don't copy U.S. figures into it.
This guide covers the 2026 amounts, the calculation order for self-employed income, standard versus itemised deductions, self-employment tax, eligibility limits and recordkeeping.
Key Takeaways
- The standard deduction lowers U.S. federal taxable income and varies by filing status.
- Business expenses come first on Schedule C; personal deductions apply later on Form 1040.
- The standard deduction does not reduce self-employment tax.
- Do not apply U.S. figures on an Australian return without checking ATO rules.
What Is the Standard Deduction?
The standard deduction is a fixed dollar amount that reduces your taxable income. You use it instead of listing eligible personal expenses one by one, according to IRS Topic 551.
Where it fits in the calculation
Five terms often get mixed up:
- Gross receipts: everything your business takes in.
- Business profit: receipts minus eligible business expenses.
- Adjusted gross income (AGI): income minus adjustments, such as half of self-employment tax.
- Taxable income: AGI minus the standard or itemised deduction.
- Tax owed: the result after other taxes, credits, withholding and estimated payments.
Business write-offs are different
Sole proprietors report income and expenses on Schedule C. Net profit flows to Schedule 1 and, where applicable, Schedule SE. The standard deduction comes later on Form 1040, and claiming it doesn't block eligible Schedule C expenses.
Filing status sets the basic amount. Taxpayers who are 65 or older, or legally blind, get an additional amount for each qualifying condition.
How the ATO differs
- Business expenses must relate to earning assessable business income. Private portions are excluded and records are required.
- Personal work-related deductions need a direct link to earning income, no reimbursement, and records.
- Australian tax residents generally declare worldwide income, including foreign business income.
Australia has no equivalent flat standard deduction.
2026 Standard Deduction Amounts and Scope
These are tax year 2026 figures, generally used on returns filed in 2027. A return filed during 2026 ordinarily covers tax year 2025. All amounts are U.S. dollars, from IRS Revenue Procedure 2025-32 and the IRS release of 9 October 2025.
| Filing status | 2025 basic | 2026 basic | 2026 addition per age/blindness condition |
|---|---|---|---|
| Single | $15,750 | $16,100 | $2,050 |
| Married filing jointly | $31,500 | $32,200 | $1,650 |
| Married filing separately | $15,750 | $16,100 | $1,650 |
| Head of household | $23,625 | $24,150 | $2,050 |
| Qualifying surviving spouse | $31,500 | $32,200 | $1,650 |
Age 65 or older and blindness are separate conditions, so the addition isn't one flat allowance per return.
Why the numbers changed
The One Big Beautiful Bill Act, enacted in 2025, raised the 2025 amounts and made the higher deduction permanent. The increases shown above are the later inflation adjustments. Use the final 2025 figures for comparison, not the lower ones announced before the legislation.
The law's separate senior deduction is a different thing from the additional standard deduction for age.
For Australian readers: these are U.S. figures. They don't create an Australian standard deduction. Check current ATO guidance for Australian-sourced income and expenses. Nonresident aliens generally can't claim the U.S. standard deduction at all, so confirm your U.S. tax status first.
How the Standard Deduction Works for Self-Employed and 1099 Workers
The calculation sequence
- Total your business income.
- Subtract ordinary and necessary business expenses on Schedule C to get net profit.
- Calculate self-employment tax on Schedule SE.
- Subtract adjustments to income, including half of SE tax, to reach AGI.
- Subtract the standard deduction (or itemised deductions) to reach taxable income.
You can claim business deductions and the standard deduction together. Mileage, home office, software and supplies remain legitimate Schedule C expenses.
Self-employment tax runs on a separate base
SE tax is 15.3%, made up of 12.4% Social Security and 2.9% Medicare, applied to 92.35% of net profit, per the IRS Schedule SE. The 2026 Social Security wage base is $184,500. Schedule SE is generally required once net self-employment earnings reach $400.
The standard deduction doesn't enter that calculation. Income below the deduction can still attract SE tax.
Example: $30,000 of self-employed income
Assume a single filer with no other income, no credits, and $6,000 of business expenses.
- Net profit: $24,000
- SE earnings: about $22,164 (92.35%)
- SE tax: about $3,391
- Half of SE tax, deducted from income: about $1,696
- Standard deduction (single): $16,100
- Taxable income: about $6,204
Change any assumption (expenses, filing status, other income, credits, state tax) and the answer moves. No universal figure exists for gross income alone.
Estimated tax basics
Estimated payments are generally needed when you expect to owe $1,000 or more after withholding and credits. The usual safe harbour is the smaller of 90% of current-year tax or 100% of prior-year tax (110% if prior-year AGI exceeded $150,000). Calendar-year 2026 instalments fall due on 15 April, 15 June, 15 September and 15 January 2027, per Form 1040-ES.
A 1099-NEC threshold isn't a tax-free threshold. From 2026, payers generally report at $2,000, but the income is taxable regardless.
Standard vs Itemized Deductions
Standard vs Itemised Deductions
Eligible taxpayers generally pick whichever gives the lower taxable income. Revisit the choice every year.
Common itemised deductions for 2026:
- State and local taxes: capped at $40,400 ($20,200 if married filing separately), with a phase-down at higher incomes.
- Medical expenses: only the portion above 7.5% of AGI.
- Mortgage interest: generally on up to $750,000 of qualifying debt.
- Charitable gifts: a 0.5% AGI floor applies from 2026.
Non-itemisers may also claim up to $1,000 ($2,000 joint) for eligible cash gifts, separate from the standard deduction.
Business expenses aren't itemised deductions. They stay on Schedule C whichever option you choose, so don't drop them because you take the standard deduction.
The trade-off is simple. The standard deduction is quick and needs few records. Itemising can win with a large mortgage, big medical bills or substantial giving, but it demands documentation. Verify current limits before relying on them.
2026 Filing Checklist and Professional Support
Keep these on hand:
- 1099s and other income statements
- Invoices and receipts
- Mileage logs (the 2026 business rate is 72.5 cents per mile)
- Home-office measurements (simplified method: $5 per square foot, up to 300 square feet)
- Health insurance and retirement contribution records
- Proof of business purpose for each expense
Health insurance is separate
Self-employed health insurance is generally a Schedule 1 adjustment, not part of the standard deduction. It's limited by earned income from the business.
No deduction applies for months you were eligible for subsidised employer coverage, including through a spouse's employer. Form 7206 applies where required.
Cross-border caution
Where you perform services determines the source of personal-service income, not where the payer sits. A U.S. client or a 1099 alone doesn't make Australian-performed work U.S.-source.
The ATO may also allow a foreign income tax offset for qualifying foreign tax paid, but it isn't automatic. See the ATO offset guidance.

Frequently Asked Questions
What is the standard deduction and how does it work?
It's a fixed amount that reduces income subject to U.S. federal tax. It lowers taxable income, not tax dollar for dollar. Australia uses its own deduction rules under a separate tax system.
What is the standard deduction for self-employed individuals in 2026?
It depends on filing status: $16,100 single or married filing separately, $24,150 head of household, and $32,200 for joint filers or qualifying surviving spouses. Age or blindness adds more.
How much tax will I pay on $30,000 self-employed income?
It depends on net profit, expenses, filing status, other income, credits, SE tax and where you live. Use an assumptions-based calculation, like the example above, rather than a single figure.
Can I take the standard deduction if I am self-employed or receive a 1099?
Yes, if you're an eligible U.S. taxpayer. You can also deduct qualifying business expenses separately on Schedule C.
Who is not eligible to use the standard deduction?
Examples include married filing separately when a spouse itemises, most nonresident or dual-status aliens, short-year filers after an accounting-period change, and estates or trusts. See IRS Topic 551 for current rules.
Does the standard deduction reduce self-employment tax?
No. It reduces income subject to income tax only. Half of your SE tax is deductible as an adjustment, and business expenses lower the profit SE tax is based on.
