Accuracy & Corrections

1. Investigate and verify the discrepancy against official sources
2. Correct the error within 5 business days if confirmed
3. Note the correction date and nature of the change

Content Independence

TaxCalc.asia is an independent project. We are not affiliated with any government tax authority, accounting firm, or financial institution. Our calculators and content are funded entirely through advertising. No tax authority, platform, or third party influences what we publish or how we calculate.

How Numbers Enter the Site

Every tax fact passes through the same path before it appears in a calculator or an article: the enabling law or official announcement, then the relevant government publication, then a source note recorded against the number, then implementation in the calculator configuration. Before publishing, the new value is cross-checked against the previous period's configuration so silent legal changes don't slip past. When a rate or threshold moves, we update it in the calculator and in every blog post that references it — a reader should never see one number on a country page and a different one inside the tool on the same page.

Advertising Disclosure

TaxCalc.asia is funded by advertising, which is clearly displayed on pages and is never presented as editorial content. Advertisers cannot influence which tax numbers appear, how the calculators work, or which countries and topics we cover, and we do not accept sponsored placements that would require altering a calculation or a rate. If an advertisement ever looks like part of the article, that is an error — please report it so we can remove it.

What We Do and Don't Cover

The calculators cover the common freelance scenarios in our six focus countries: personal income tax, the presumptive or simplified schemes many freelancers actually use (Section 44ADA, NPPN, the Philippine 8% flat option, and their equivalents), and the resident versus non-resident distinction that expat freelancers care about. We do not attempt to cover corporate taxation, cross-border transfer pricing, full VAT or GST treatment, or multi-country legal structures. Where a topic is out of scope we say so plainly rather than guess, and we link to official sources instead.

How a Change Is Published

1. The official announcement or gazette publication is located
2. The affected country page, calculator configuration, and any referencing blog posts are listed
3. Changes are applied together so an article and its embedded calculator never disagree
4. The update is date-stamped on the page and the correction is logged
5. A second pass re-checks every number against the source document before publishing
