Disclaimer

kifinance.xyz publishes a tax bracket calculator and editorial content for informational use. The output is mathematically verified against official bracket schedules but is not regulated tax advice and not a substitute for the official Revenue/HMRC/IRS calculators in legal or contractual contexts.

Last updated:

1. Editorial accuracy

Bracket schedules are sourced from Revenue Commissioners (Ireland), HMRC (UK), and the IRS (US) and are refreshed each January after the relevant authority publishes the new tax year's rates. Each release is verified against the corresponding official public calculator.

2. No warranty

The Service is provided “as is” and “as available”, without warranties of any kind. To the maximum extent permitted by law, kifinance.xyz disclaims all such warranties.

3. Not for tax filing

The calculator does not file your tax return. It approximates your liability under the bracket schedule and basic social charges; it does not handle the full set of credits, reliefs, and deductions that affect a real return. For filing purposes, use the official Revenue, HMRC, or IRS public calculators, or engage a qualified tax adviser.

4. Not regulated tax advice on a specific matter

The named reviewer is a qualified Chartered Tax Adviser. The site itself, however, is editorial and does not constitute personalised tax advice on a specific client matter. For binding advice on your particular circumstances, retain a qualified adviser. Verify any Irish CTA via the Irish Tax Institute directory.

5. Limited scope by jurisdiction

US figures are federal income tax and FICA only. State and local income taxes are not modelled and can add 0–13 % to the marginal burden depending on jurisdiction.
Ireland figures use illustrative single-status rates with the personal tax credit. Married, civil partner, and one-parent-family bands are not separately modelled.
UK figures use England/Wales/Northern Ireland rates. Scottish rates differ above the personal allowance and are not currently modelled.

6. Limitation of liability

In no event will kifinance.xyz, its editors, contributors, hosting providers, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages arising out of use of, or inability to use, the Service.

Where liability cannot be excluded, our aggregate liability is limited to one hundred euros (€100).

7. Third-party content

References to Revenue Commissioners, HMRC, IRS, the Irish Tax Institute, the Bar of Ireland, Microsoft Excel, Google AdSense, and other trademarks are for identification only.

8. Changes

Material revisions reflected in the “Last updated” date above. The bracket-schedule refresh date is logged separately on the calculator.
