The 2026 Standard Deduction

For 2026, the standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household. Roughly 90% of taxpayers take the standard deduction because itemizing rarely exceeds it after the 2017 tax law changes.

What Counts as Itemized Deductions

Itemized deductions include: state and local taxes (capped at $10,000), mortgage interest, charitable contributions, medical expenses exceeding 7.5% of AGI, and casualty losses. To benefit, your total must exceed your standard deduction.

When Itemizing Wins

Itemize if you: pay high mortgage interest in an expensive home market, make large charitable contributions, had major medical expenses, or pay substantial state income and property taxes. A $600,000 mortgage at 6% generates ~$35,000 in interest — enough to beat the standard deduction alone.

The Self-Employed Advantage

Self-employed individuals get the best of both worlds: business expenses are Schedule C deductions (taken in addition to the standard deduction), while personal expenses can still be itemized. Your home office, equipment, and insurance premiums don't force you to give up the standard deduction.

Frequently Asked Questions

Can I take the standard deduction AND business deductions?

Yes. Business expenses on Schedule C are separate from the standard/itemized choice. Self-employed workers take the standard deduction plus all business deductions — one of the biggest tax advantages of self-employment.

Is the SALT cap still $10,000 in 2026?

Yes. The state and local tax deduction remains capped at $10,000 ($5,000 married filing separately). Several proposals have been floated to raise it, but as of the 2026 tax year the cap stands.

How do I know which option is better?

Add up your potential itemized deductions. If they exceed $16,100 (single) or $32,200 (married), itemize. Tax software computes both automatically, but a quick manual estimate usually tells you which path wins.

How these numbers are produced

Calculations follow the order of operations on the IRS forms themselves: net profit, the 92.35% adjustment, self-employment tax, the 50% deduction against AGI, the standard deduction, the §199A QBI deduction with its phase-out, then the federal brackets. State tax is computed separately on state AGI less that state's own standard deduction, because no state allows the federal QBI deduction and almost none allow the federal standard deduction.

What it does not cover. The calculators model a single filer or a married couple filing jointly with self-employment income as the main source. They do not model local income taxes, W-2 wages held alongside freelance work, itemized deductions, the alternative minimum tax, or credits. Where a local income tax exists, it is described on that state's page.

Not advice. SelfTaxCalc produces estimates, not tax advice. No one here is a CPA, an enrolled agent or a tax attorney, and nothing on this site creates a professional relationship. Estimates are a starting point for planning and for a conversation with a professional — they are not a substitute for one.
