About TaxWise

TaxWise is a free income tax and personal finance calculator suite. It started as a tool for Thai civil servants and salaried employees to understand their tax burden and claim every deduction they're entitled to — without spreadsheets or manual math. The site now supports both Thailand 🇹🇭 and the United States 🇺🇸, with calculators and figures tailored to each country's tax rules.

What We Do

• Real-time federal income tax calculators — for the US, this covers your tax bracket, the standard deduction, and savings from 401(k), Traditional IRA, HSA, and student loan interest deductions. The Thailand version covers GPF, RMF, SSF, ThaiESG, and Solar Rooftop deductions.
• Six additional financial planning tools — Rent vs Buy, Compound Interest/DCA, Retirement Planning, Loan/Amortization, Portfolio Allocation, and a general Finance Calculator, all localized with country-appropriate figures.
• Guides and articles that explain tax law and deduction rules in detail, updated for the current tax year.

Our Principles

Everything on this site is provided for educational purposes only. It is not tax, legal, or investment advice. Figures and rates are based on publicly available guidance from the IRS (for the US) and the Thai Revenue Department (for Thailand), but tax law changes — always confirm with the IRS, the Revenue Department, or a licensed tax professional before making real financial decisions.
