Accounting and Bookkeeping for Small Businesses in India 2026: GST, TDS and Compliance Made Simple

For a small business in India, good accounting and bookkeeping comes down to three things: file your GST returns on time, deduct and deposit TDS when you pay vendors, and keep clean records of every sale and expense. Do these and you avoid almost all penalties and the costly mistakes that even a busy CA can miss. Most fines happen not because the tax was wrong, but because a return was late or a record was missing.

Start with GST. You must register if your yearly turnover crosses Rs 40 lakh for goods or Rs 20 lakh for services in most states (lower limits apply in special category states like the North-East). If you are small and sell mostly within your own state, the Composition Scheme (turnover up to Rs 1.5 crore, or Rs 50 lakh for services) lets you pay a flat 1% for traders and manufacturers and file just once a quarter. The catch is you cannot claim input tax credit, so weigh it carefully.

For regular GST, the two returns that matter most are GSTR-1 (your sales, due by the 11th of the next month) and GSTR-3B (your summary and tax payment, due by the 20th). Miss the date and the late fee is Rs 50 a day (Rs 20 for a nil return), plus 18% interest a year on tax paid late. These small amounts add up fast, so set a calendar reminder.

Next is TDS, the tax you cut from certain payments before paying the other side. Pay a professional like a CA or designer? Deduct 10% once their yearly fee crosses Rs 50,000 (Section 194J, where the limit rose from Rs 30,000 to Rs 50,000 from FY 2025-26). Pay a contractor? Deduct 1% for individuals once a single bill crosses Rs 30,000 or the year crosses Rs 1 lakh (Section 194C). Pay office rent above Rs 50,000 a month (Rs 6 lakh a year)? Deduct 10%. Note that the new Income Tax Act, 2025 takes effect on 1 April 2026 and re-numbers these TDS rules (rates stay the same), so check the latest section before you file.

The simplest habit that protects you: record every bill the same week, keep your business money in a separate bank account, and save soft copies of invoices for at least six years. Clean books make your GST and TDS filing almost automatic and give your CA less room for error. This is general information, check the official source or a qualified CA before you act.

File GST and TDS on time and keep clean records, and you dodge nearly every penalty a small business faces.
