Cookies

The site sets Google Analytics audience measurement cookies and those alone: no advertising cookie, no social media cookie. Details of the processing are in the privacy policy.

Cookies set

Name	Provider	Purpose	Lifetime
`_ga`	Google Analytics	Tell visitors apart with a random identifier	13 months at most (390 days)
`_ga_772NCNB8YX`	Google Analytics	Keep the state of the current visit	13 months at most (390 days)

These lifetimes are not extended on each visit; Google’s default is 2 years and the site shortens it. Purpose: audience measurement (pages viewed, referrer, device, approximate country). The IP address is anonymised: Google Analytics 4 neither logs nor stores it. No advertising and no ad sharing: ad storage, ad personalisation and Google signals are switched off.

Provider: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Data may be transferred to Google LLC in the United States under the EU–U.S. Data Privacy Framework and the European Commission’s standard contractual clauses. Retention at Google: 14 months. Legal basis: the publisher’s legitimate interests (Article 6(1)(f) GDPR; for visitors in the United States, no personal information is sold or shared within the meaning of the CCPA/CPRA).

Results are estimates built from each state’s published rule, your figures and the assumptions you set (return, cost rise). They are not tax, legal or investment advice for your own case; your state revenue department or a tax professional can confirm it. Nobody pays us to point you to a plan.
