Tax Advance is an app for planning and estimating personal income tax.
Before filing, it helps you know in advance how much tax you need to pay or how much you'll receive in refunds this year.
Plan your finances in a timely manner, without waiting until the end of the year.

Main Features:
- Record multiple income streams and items per year.
- Calculate tax according to the actual progressive tax rates of the Revenue Department, with details of each step.
- Supports a full range of deductions: spouse, children, adopted children, parents, disabled/handicapped persons, personal life/health insurance, parents' health insurance, LTF/RMF/pension funds, social security, housing loan interest, charitable donations, and other government tax measures.
- Record multiple individuals in the same year (e.g., husband and wife) with a summary of the total for the entire family.
- View past/future income for several years, with graphs of income and tax trends.
- The "File" system allows you to record multiple families/clients in one app.
Ideal for accountants, insurance agents, or those who manage taxes for others.
- Set default settings (templates) for recurring monthly income; enter once and reuse.
- Save results directly to your device's photo album as an image. - Export as a PDF file.
- Backup/import data with files. Choose storage location both locally and in the cloud (Google Drive, OneDrive, etc.) to prevent data loss when changing devices.

Suitable for:
- Freelancers, business owners, and those with multiple income streams.
