What will you actually owe in April?

Nine questions. Most S-corp owners are surprised by the gap between what they've paid in and what's coming.

Your situation
Engineering and architecture are excluded from the SSTB definition — answer no.
This year's numbers
Full year, not year to date. Business profit before anything paid to you.
Full-year expected.
Spouse's wages, or a second job.
Total payroll excluding your own. Used for the §199A wage limitation, which only bites above the threshold.
Cash you've moved out of the business this year.
What you've paid in
Include income tax withheld from your paychecks. Not payroll taxes.
Form 1040, line 24. This decides whether you're inside the safe harbor — leave it at zero if you don't have it handy.

What this estimate does — and what it can't know.

Distributions are not part of the tax calculation, and that's not an oversight. An S-corp distribution isn't a taxable event. You're taxed on your share of the business's income whether or not a dollar leaves the account. We ask about distributions because that's usually why the estimates stopped matching — the cash moved, the payments didn't.

The math uses 2026 federal brackets and 2026 Oregon rates. It computes your §199A deduction the way Form 8995-A does — the taxable-income threshold, the W-2 wage limitation and its phase-in, and the separate SSTB phase-out. Oregon doesn't follow §199A, so no deduction is applied there.

What it doesn't see:

  • Whether your compensation is defensible — a low salary shows here as a smaller tax bill and a larger problem
  • Itemized deductions, retirement contributions, credits, or a spouse's own business
  • UBIA of qualified property, which raises the §199A deduction for asset-heavy businesses
  • Your basis, so it can't tell you whether distributions exceeded it
  • Capital gains, rental activity, other K-1s, AMT, or the net investment income tax
  • Guaranteed payments, which change the partnership answer
  • Whether Oregon's PTE-E election would be worth making

Any one of those moves the number. That's what the diagnostic is for.
