What to Include
To help us respond faster, please include:
- The country calculator you were using
- A description of the issue or suggestion
- For calculation discrepancies: your input numbers and the result you expected vs. what you got
Report a Calculation Error
If our calculator gives a different result from an official government source or your accountant, please let us know. We regularly update our tax engines and want to ensure accuracy. Include the tax year, country, your income amount, and the discrepancy you found.
Request a New Country
We're working on adding more countries. If there's a specific country you'd like us to cover, send us an email and tell us why it matters. Popular requests get prioritized.
What This Site Covers
TaxCalc.asia builds free calculators and guides for freelancers, digital nomads, and one-person businesses in Southeast Asia and India. We currently maintain detailed tax engines for the Philippines, Indonesia, Malaysia, Thailand, Vietnam, and India, plus a cross-country comparison tool for deciding where to bill from.
Beyond the main income-tax calculators, the site ships a take-home pay tool, a freelance rate calculator, an invoice generator, a retirement calculator, and fee models for Upwork, Fiverr, PayPal, and Wise. If you use any of these and something behaves unexpectedly, that is exactly the feedback we want.
What We Can Help With
- Explaining how a calculation works and the inputs it uses
- Confirming whether a tax figure on the site matches an official 2025 rule change in your country
- Suggesting which guide applies to a specific situation (freelance visa, residency, invoicing, deductions)
- Helping publishers embed the calculator widget on their own site
- Anything that's broken, confusing, or slow
We are a small team and cannot act as your accountant or give personalised tax advice. For a binding answer on your own filing, confirm figures with the relevant revenue authority or a local professional.
Before You Write
Most questions already have an answer on the site:
- Country tax rules and filing steps are explained on each country page and their linked guides
- How rates, brackets, and thresholds are sourced and kept current is detailed in our editorial policy
- Website usage, cookies, and data handling are covered in our terms of service
If the answer isn't there, email us — the more specific your question, the faster we can reply. For tax-season questions, expect a slower response during peak filing months.
Corrections and Accuracy
Tax rules change every year, and local interpretations vary by region within a country. If you spot an out-of-date bracket, a wrong deduction limit, or a threshold that conflicts with an official source, please report it with the link. We triage accuracy fixes ahead of feature requests and will publish corrections quickly, noting the change below the affected page.
Privacy and Data
The calculators run entirely in your browser — nothing you type is stored or sent to us. We use basic analytics and a privacy-respecting cookie policy, described in the terms of service. If you have a specific privacy concern that isn't covered there, mention it in your email and we'll answer it directly.
