About the calculators
How accurate are the CalcYet calculators?
For the federal income tax + FICA portion, our calculator matches actual paystub withholding within roughly $1-3 per pay period when you enter the same pre-tax deductions and filing status. We document this in our accuracy study. For the state portion, accuracy depends on how completely we’ve modeled the state — some states have local wage taxes or paid-leave premiums that we model explicitly (NYC, Philadelphia, CA SDI, WA PFML), others where we don’t (a few smaller Ohio cities, certain Indiana counties) where the result can be $20-80 a year off. Our methodology page lists what we include and exclude state-by-state.
Why does my actual paycheck differ from the calculator output?
Three common causes, in order of frequency. First, a pre-tax deduction you didn’t enter in the calculator — 401(k), HSA, FSA, Section 125 health premium, commuter. The calculator gives you fields for all of these but you have to fill them in. Second, a state-specific premium the calculator doesn’t model — California SDI, New York PFL, Washington PFML, New Jersey TDI/FLI. Third, a supplemental withholding event that pay period (bonus, commission, retroactive pay) using the IRS’s 22% flat method. If your check is more than $20-30 off after checking those three, email corrections@calcyet.com with the details and we’ll investigate.
Can I use the calculator results to file my taxes?
No. These are planning estimates suitable for offer-letter comparisons, W-4 adjustments, and cash-flow planning. They are not filing-quality numbers. For filing you should use tax software, a CPA, an Enrolled Agent, or the IRS Free File program. We discuss why we draw that line in our methodology page.
Do the calculators model multi-job withholding?
Partially. The W-4 calculator has a field for “additional income” and a Step 2(c) equivalent to model multi-job households. The take-home pay calculator assumes a single primary job for its baseline figure. If you have two jobs of meaningfully different income, the right approach is to run each separately, then run the W-4 calculator with the combined income to compute the right additional withholding for whichever job uses Step 4(c).
What years are the calculators set up for?
Tax year 2026 throughout. Federal brackets come from IRS Revenue Procedure 2025-32. The Social Security wage base is the SSA’s 2026 figure of $176,100. State rates are 2026. We refresh the dataset in the late October to early November window when the IRS publishes the next year’s inflation adjustments. The historical changes are tracked at our tax law changelog.
Editorial and methodology
Who writes the content?
Three credentialed authors plus a senior reviewer. Maria Thompson is a CPA licensed in California and Texas. David Chen is an IRS Enrolled Agent. Sarah Patel holds a Master of Science in Taxation. Robert Johnson, CPA, JD-Tax serves as senior reviewer. All bios, license jurisdictions, and educational background are on the editorial team page. We do not publish anonymous content.
Is CalcYet content written by AI?
No. Each article is written by a named, credentialed human author and reviewed by a second credentialed human reviewer before publication. AI tools may be used by editors for tasks like outline drafting, summarizing statute text for research, or grammar checks — the same way you’d use a research assistant or a copy editor. Every published sentence is reviewed and edited by a human author, and every numeric example is independently verified by a second human reviewer. The policy is documented at our editorial policy.
How do you decide what to write about?
Mostly from the contact form, the corrections inbox, and the patterns we see in our own practice. If we get the same question three times in a month we usually decide to write a piece about it. The secondary input is statute change — when the IRS publishes a new revenue procedure or a state adjusts its rates, we update the relevant articles and (where the change is meaningful) add a changelog entry.
Can I suggest a correction?
Yes, please. Email corrections@calcyet.com with the article URL, the specific sentence at issue, the corrected fact, and a primary source supporting the correction. We acknowledge within two business days and resolve verified errors within five business days of confirmation, with a dated note added to the affected page.
Why don't you cite social media tax advice?
Because most of it is wrong. The “tax-saving hacks” that get traction in short-form video typically fail one of three tests — they confuse marginal and effective rates, they ignore phase-outs, or they describe a provision that doesn’t exist the way the creator described it. We have a longer note on this on our resources page. We cite credentialed practitioners on professional platforms occasionally; we don’t cite anonymous accounts no matter how viral.
Privacy and data
Do I have to create an account to use the calculators?
No. None of the calculators require an account, an email address, or any personally identifying information. Calculations run client-side in your browser; nothing about the numbers you enter leaves your device. The full privacy treatment is at our privacy policy.
What data does the site collect?
Standard web analytics (Google Analytics in IP-anonymized mode), cookie-consent state, and advertising data for users who have consented under our cookie banner. We don’t collect anything about your tax inputs or your specific calculator usage tied to a personal identifier. The privacy policy lists every category in detail.
Are the calculators free?
Yes. Always. No subscription, no email gate, no “upgrade to see the answer” pattern. The site is supported by display advertising under Google AdSense program policies. Editorial decisions are walled off from advertising; see our editorial policyfor the structure.
Citations, press, and reuse
How do I cite a CalcYet article in research?
The format we suggest is: Author, Last name. (Year, Month Day). Article title. CalcYet. URL. The full press and citation guide is at our press page. You don’t need permission to quote or paraphrase — a link back to the source page is appreciated.
Can I embed a CalcYet calculator on my own site?
We don’t currently offer a public embed API. If you have a specific use case — a financial-planner’s portal, a university financial-literacy program, a nonprofit’s client services — reach out to contact@calcyet.comwith the details and we’ll consider it.
Will you write a custom article for our company?
No. We don’t accept paid placements, paid links, paid mentions, or sponsored content. The editorial calendar is set by the editorial team based on reader questions and statutory change. Press, factual comment, and on-record interviews are welcome and free; sponsored content is not.
Specific tax topics our readers ask most
How much should a freelancer set aside for taxes?
More than 25%. The honest set-aside percentage for a single full-time freelancer in a no-state-tax state is roughly 28-32%; in a mid-tax state 32-36%; in a high-tax state (CA, NY) 36-40%. The common “just put 25% aside” rule ignores self-employment tax, which is on top of (not inside) the federal income tax. See our 1099 set-aside guide for the math.
Will a raise push me into a worse tax bracket and make me lose money?
No. The US uses a progressive marginal system — only the dollars inside a higher bracket are taxed at that bracket’s rate. Earning one more dollar can never reduce your net pay. See the brackets explainer. The “bonus check looks small” feeling is a supplemental-withholding mechanic, not a bracket effect; that’s explained in the same article.
I live in Florida and work remotely for a New York company. Do I owe New York tax?
Yes, under New York’s convenience-of-employer rule, almost certainly. Florida has no state tax to credit against, so the full New York non-resident tax is a pure cost. On a $180,000 salary that’s roughly $12,000 a year. The full mechanics are in our multi-state filing guide and the dollar analysis is in the convenience-rule cost piece.
Should I contribute to a Roth or traditional 401(k)?
Traditional if your current marginal rate is higher than your expected retirement marginal rate; Roth if the reverse. For most working professionals in their peak earning years, traditional wins. For early-career workers in low brackets, Roth often wins. The full break-even reasoning, including the residency-planning wrinkle, is in our pre-tax vs post-tax piece.
Should I fund the HSA or the 401(k) first?
Take the full 401(k) employer match first — that’s a guaranteed pay raise. Once you’ve hit the match, max the HSA before adding more 401(k) (if you’re on an HSA-eligible high-deductible plan). HSA reduces both federal income tax and FICA wages; traditional 401(k) reduces only federal income tax. That extra 7.65% saving on every HSA dollar matters.
How do quarterly estimated tax payments work?
For freelancers, contractors, and anyone whose withholding doesn’t cover their liability. Four payments a year due April 15, June 15, September 15, and the following January 15. Avoid the underpayment penalty by meeting safe harbor: 90% of current-year liability or 100% of prior-year (110% if prior-year AGI exceeded $150,000). Full mechanics in our quarterly tax guide.
What's the difference between a tax deduction and a tax credit?
A deduction reduces taxable income; its value equals your marginal rate times the dollar amount. A credit reduces tax dollar-for-dollar. A $1,000 deduction in the 22% bracket saves $220; a $1,000 credit saves $1,000. Refundable credits can even produce a refund larger than tax owed. See our deductions-vs-credits piece for the credits most filers miss.
