MANILA - It is that time of the year again when taxpayers are expected to file their annual income tax return (ITR), a task that is relatively easy for regular employees, but can prove to be a pain for freelancers and home-based employees.

Aside from beating the annual deadline, freelancers also have to go through the process of filling out forms and submitting them both online and in person.

Raymond Abrea, president and CEO of Abrea Consulting Group, said one of the most important things a taxpayer should check is whether he or she is using the right form.

There are different forms available at the Bureau of Internal Revenue (BIR). These include Form 1700, which is purely for compensation income earners; 1701, which is for self-employed or mixed income earners; 1702-RT which is for corporations, and 1702-EX which is for foundations.

Aside from ensuring that you have the right form, a taxpayer should also double check numbers before encoding.

Those who don't have a tax consultant could also make their own review of their 2015 returns.

The annual income tax return is just a summary of what you should have declared or reported in your monthly tax returns.

How do you do your own tax compliance review? Make sure you have the right supporting documents.

Among the documents you can use in reviewing your taxes are books of accounts, schedules of expenses, official receipts or invoices, list of sales and purchases, and inventory of sales.

To make it easier to track your taxes, it is advisable to record your income properly every time you receive it.

It is also better to always issue receipts, whether or not your clients ask for them.

Finally, in order to avoid stressing over the deadline, prepare and review your tax documents every end of the month.

"Ignorance is very costly. It's best to hire a good accountant when it comes to handling your books and taxes, or at least ask the right people and not a fixer," Abrea said.

The deadline for filing income tax returns is on April 15.
