Taxation for a partnership firm with an annual turnover of up to 1 crore involves several aspects, primarily governed by the Income Tax Act of India. Here’s a general description:

1. Income Tax Return (ITR): Like any other entity, a partnership firm needs to file its income tax return annually. The form to be filled depends on the structure and income of the partnership firm. For example, if the firm’s turnover is less than ₹1 crore, it may file Form ITR-5.
2. Income Tax Rates: Partnership firms are taxed at a flat rate of 30% on their total income. Additionally, a surcharge is applicable if the income exceeds a certain threshold. However, if the total turnover of the partnership firm does not exceed ₹1 crore, it can opt for a presumptive taxation scheme under Section 44AD of the Income Tax Act.
3. Presumptive Taxation Scheme: Under Section 44AD, if a partnership firm’s turnover is up to ₹1 crore, it can declare income at a prescribed rate (typically 8% of total turnover) without maintaining detailed books of accounts. This scheme simplifies taxation procedures for small businesses.
4. Deductions and Exemptions: Partnership firms can claim deductions for expenses incurred wholly and exclusively for business purposes, such as rent, salaries, utilities, and depreciation on assets. However, specific rules and limits apply to each deduction.
5. Compliance Requirements: Partnership firms must comply with various tax-related requirements throughout the year, such as quarterly advance tax payments, maintaining books of accounts, getting accounts audited if turnover exceeds a certain limit, and filing tax returns within the due dates.
6. GST Compliance: If the partnership firm’s turnover exceeds the threshold limit for GST registration, it must register for GST and comply with GST rules, including filing regular returns and maintaining proper records of transactions.
7. Tax Deducted at Source (TDS): If the partnership firm makes payments subject to TDS (like salaries, rent, or professional fees), it must deduct tax at the applicable rates and deposit it with the government within specified timelines.
8. Tax Planning: Partnership firms should engage in tax planning activities to optimize their tax liabilities legally. This may include exploring deductions, incentives, and exemptions available under the Income Tax Act.
9. Penalties and Interest: Non-compliance with tax laws can lead to penalties and interest payments. It’s essential for partnership firms to stay updated with tax regulations and fulfill their obligations promptly to avoid such consequences.

Overall, taxation for a partnership firm with an annual turnover of up to 1 crore involves adherence to various tax laws, filing requirements, and compliance obligations, with the possibility of opting for presumptive taxation to simplify the process. Consulting with a tax advisor or chartered accountant can help ensure accurate compliance and tax optimization.
