About wastudio.tech

wastudio.tech is the public site of a technology studio that builds simulators and calculation tools to make complex tax and regulatory systems easier to explore — for founders, freelancers, and small-business owners.

Why wastudio.tech instead of a product-specific domain?

Visitors often expect a name like us-tax-calculator.com or sole-prop-simulator.net. We chose differently because of what we actually do.

At our core we are a calculation studio. We design and ship simulators that turn multi-layer rules — federal brackets, payroll taxes, entity elections, dividend stacking — into interfaces people can use before talking to a professional.

The name wastudio.tech reflects that identity:

  • studio — a product and editorial workshop, not a single landing page;
  • .tech — signals engineering and software, beyond one tax topic;
  • wastudio — one brand across France, US, UK and Germany editions.

The US calculators on this site are our first major public application of that expertise. The brand names who we are (a studio that builds simulators), not only what one page does today.

Mission

We publish transparent, assumption-heavy calculators so founders can orient conversations with enrolled agents and CPAs. Nothing here replaces professional advice, audit defense, or state-specific compliance (sales tax, franchise tax, PTE elections, etc.).

What we model

  • Federal ordinary income brackets for single filers with the standard deduction (indexed values).
  • Self-employment tax using 92.35% of net earnings as the statutory base, split between Social Security and Medicare portions with the Social Security wage cap.
  • Optional QBI deduction at 20% of pass-through profit without the detailed wage/capital limitations of IRC §199A.
  • S-Corp wage vs. distribution split with a user-provided reasonable salary and illustrative FICA stacking.
  • C-Corp 21% corporate tax plus qualified dividend rates on post-tax distributions.
  • A purely illustrative state tax slider (0–13.3%) applied to net business profit — not sourced to any single state formula.

Editorial independence

Articles are researched from primary IRS and Treasury releases. When guidance is ambiguous, we label the range and link to the underlying notice or publication. Sponsored placements, if any, are separated from methodology pages.
