KeptOffer is an independent take-home pay site for the United States (NY, CA, FL, TX), the United Kingdom, Australia and Canada. The headline salary is the recruiter's number. KeptOffer shows the part that reaches your account.
The four tools are Net (gross to in-hand, line by line), Offer (two job offers after tax, in one currency, with the salary that would make them equal), Move (does the raise survive the move?) and House (28% of net, then OwnerCost for the full cost of owning).
Tax rules live in a versioned registry for each country (US v1.0.0, UK v1.0.0, AU v1.0.0, CA v1.0.0, reviewed 2026-09-30). Every rate and threshold cites its official source: GOV.UK and HMRC, the ATO, the CRA, the IRS, the SSA, California's FTB and EDD, and New York's Department of Taxation. Where a figure is a modelling choice or a value held from last year, the result says so next to the number.
