Filing Taxes Online Is Easier Than You Think: Here's How to Do It for the First Time

If you've just started working or your income has reached the threshold set by law, dealing with taxes can feel like a complicated and confusing process. But online tax filing is actually something anyone can understand and handle on their own - right from their computer or phone. Here's a detailed walkthrough of exactly how it works.

Tax filing is the process of summarising all income earned throughout the previous year and reporting it to the Revenue Department. Anyone whose income meets the minimum threshold set by law is required to file - whether you're a salaried employee, a freelancer or a business owner. Filing typically takes place between January and March each year. If you choose to file online, the Revenue Department extends the deadline to early April, giving you extra time to gather your documents and prepare.

If you're a first-timer, you might not know where to begin or what documents you'll need. Here's a clear, step-by-step breakdown of the process through the Revenue Department's website, so you can follow along confidently at every stage.

Start by visiting the Revenue Department's e-Filing website. If it's your first time, you'll need to register as a member. Have your national ID number and basic personal details ready to verify your identity. Once registered, you can log in using your ID number and the password you've set. Alternatively, you can log in through a connected app with digital identity verification for a faster and more secure experience.

Once logged in, the system will ask you to select the tax return form that matches your income type. If you're a salaried employee with income from a single source, choose P.N.D 91. If you have income from other sources as well - such as freelance work, online selling or rental income - you'll need to use P.N.D 90. Selecting the correct form ensures your tax calculation is accurate.

After selecting your form, enter your total annual income as shown on your withholding tax certificate - known as the 50 Bis (50 ทวิ) form from your employer. Then fill in all applicable tax deductions, such as life insurance premiums, tax-deductible investment funds or home loan interest. The system will automatically calculate your net income and the amount of tax you owe - or are entitled to receive back - reducing the chance of manual calculation errors.

Before submitting, go back through your income figures and deductions one more time to make sure everything is correct. If there's an additional tax amount due, the system will show you the available payment options. If you're entitled to a refund, you can check the status of that separately after submission. Once everything looks right, confirm your submission. And don't forget to save or print your receipt as proof of filing.

Beyond managing your taxes, having a broader financial plan in place is just as important.
