Anna Nagar has plenty of salaried professionals who genuinely never think about advance tax — their employer deducts TDS every month, and by the time they file their return, most of the liability is already settled. Shop owners and small business owners in the same neighbourhood don't have that safety net, and it's the single biggest reason business owners end up with an interest charge that a salaried neighbour never sees.
Nobody is withholding tax on your behalf
If you run a business and expect to owe more than ₹10,000 in tax for the year, you're required to pay it in four installments through the year — June, September, December, and March — based on your own estimate of annual income. There's no employer doing this automatically, which means it only happens if you actively estimate and pay it yourself.
Why the estimate is harder for a business than a salary
A salaried income is predictable months in advance. A shop or trading business's income can swing significantly quarter to quarter — a strong festive season, a slow monsoon stretch — which makes the June and September estimates genuinely harder to get right than they look. Underestimating early and catching up in December and March is common, and it still attracts interest on the shortfall for the earlier quarters.
The interest adds up faster than it seems
Interest under Sections 234B and 234C accrues on any shortfall against what should have been paid by each installment date, calculated monthly. For a business owner who pays nothing until March and settles everything at filing time, that interest can run to a meaningful amount — entirely avoidable with a reasonably accurate quarterly estimate instead.
