1. Know Your Tax Obligations
All self-employed persons must report the income earned from their business operations as business income, and not as salary. The business income is part of the total personal income which is taxed at individual income tax rates.
You are a self-employed person when you earn a living by carrying on a trade, business, profession or vocation. Generally, sole-proprietors and partners registered with the Accounting and Corporate Regulatory Authority (ACRA) are self-employed.
To check whether you are a self-employed person, please refer to Am I a Self-Employed Person.
2. Decide on the Accounting Period
Every year, you declare your business income for a specific accounting period. The accounting period is usually a 12-month period of trade for which you calculate your profits or losses.
You should decide on your accounting period when you first start your business. Most businesses choose accounting period that ends on 31 Dec each year. You may choose an accounting period that ends on any date.
