Contact CalcPaid
One address, for questions about how a calculation works, corrections to a tax figure, and anything the site gets wrong.
Email is the only contact channel. There is no form to fill in, no account to create, and nothing you have to tell us about yourself to ask a question.
Reporting a figure that looks wrong
This is the most useful message you can send, and the one worth a little extra detail. A correction is quickest to check when it includes:
- the state and the tax year shown on the page;
- the figure the calculator produced, and the figure you expected;
- the published source you are comparing against — an IRS notice, a state revenue department page, or the relevant bulletin.
Every rate, bracket and threshold in the calculator is stored with the authority it came from and the date it was last checked, so a message that names its source can be reconciled against ours directly. The about page explains how that data is kept.
Please do not send your own pay details
Nothing you type into the calculator ever leaves your device, and an email is a different matter entirely — it travels through mail servers and it is stored. A question about a calculation almost never needs your real salary in it: a rounded example figure demonstrates the same thing. See the privacy page for what the site itself collects: visit statistics through Google Analytics, and never the figures you type.
What this address cannot do
CalcPaid publishes estimates built from public tax rules. It is not a tax preparer, an accountant, a law firm or a payroll provider, and nothing sent in reply to an email is personal tax, legal or financial advice. In particular, we cannot tell you what your employer will actually withhold — that depends on your W-4, your benefits elections and your employer's own payroll method. The disclaimer sets out the difference in full.
Suggestions for what to build next
Tax, tip, loan and mortgage calculators are planned on the same engine as the paycheck calculators. If one of them would solve a problem you have right now, saying so — and saying what specifically it would need to handle — genuinely affects the order they are built in.
