Sources and updates
The site is based on a mix of public data, official rules, and explanatory content. Where possible, important Swedish calculators should be traceable back to the responsible authority or another clear source.
Examples of important sources
For Swedish taxes and tax tables, the primary source is Skatteverket. For parental benefit and temporary parental benefit, Försäkringskassan is an important reference point. For other topics, the site uses established rules, public guidance, or standardized formulas depending on the type of calculator.
How to interpret updates
A page may be updated based on the rules and data that were available when the content was written or last reviewed. If rules change quickly, a page may still need to be revised. That is one reason important decisions should always be double-checked against official information.
