Advance tax 15 September, how much is the 45 percent cut

Matching tool: Advance tax calculator
I almost missed 15 September last year. 45 percent is the line that bites. Shop on Tonk Road was busy with school bags. I told myself income tax can wait till Sunday. Sunday was 16th. Challan still went. Interest later made a small ugly face when I filed ITR.
Typical pattern people talk. 15 June 15 percent. 15 September 45 percent. 15 December 75 percent. 15 March 100 percent. These are cuts of estimated tax for the year. Not GST 11 and 20. Different portal. Different fear.
If you want the year split on one screen, open Advance tax calculator on PayByDate. Annual estimate. See the four dates. Then pay on the income tax portal and confirm.
This is an estimate. Confirm on the official portal.
What 45 percent even is
It is not 45 percent of your income. It is 45 percent of the tax you think you will owe this year.
I sit with a notebook. Profit guess. Other income. TDS already cut. Deductions if I still play that game. Tax leftover. That leftover is the cake. June should have eaten 15 percent of the cake. By 15 September the plate should show 45 percent eaten. So September challan is usually 45 minus what you already paid.
If June was blank, September wants the full 45 in one sitting. That shock is a separate article. Missed June instalment, what happens in September.
If June challan is in a file, you still owe more now. I paid some advance tax already, how much more now.
I am not CBDT. Threshold talk I hear: if tax after TDS is below a number people say 10,000, advance tax may not be your street. Salary-only people often live on TDS. Still I check. Salary only, do I still pay advance tax.
Freelancer with 9 lakh and no Form 16, 15 September still has a cut. Advance tax for freelancer 9 lakh.
Notebook I used last September
Tea. Paper. Last year ITR tax as a starting guess. This year shop is a bit up. I added 10 percent mood. Not science.
Then I reduced TDS the clients already cut. TDS deducted, do I reduce it from advance tax. Yes, typical story, TDS is already tax paid. Dont pay twice like a fool.
Then I looked at June challan. Small. Then 45 percent of the leftover tax minus June. That rupee I put as September.
Then I opened Advance tax calculator. Typed annual estimate. It split Jun Sep Dec Mar. I compared with my paper. Close enough for tea.
Then I paid. First time box confusion is real. First time advance tax, which box to fill first. I fill tax amount first. Not random codes from WhatsApp.
Challan print in the same file as GST papers but I dont mix the due dates on the calendar sticker. GST 11 and 20. Advance tax 15 Jun 15 Sep 15 Dec 15 Mar.
Interest if you miss 15 September
People talk of 234C. I dont recite sections like a priest. I say interest on shortfall if you paid too little by that date.
Last year I missed by one day. Interest was not a shop-shutter amount. Still it showed when I filed. Ugly because I had the cash on 14th and I was lazy.
If you underpay a lot, interest is more. If you overpay, you wait for refund mood later. I try to be near, not perfect. Estimate changes in December when Diwali sale is counted.
Missed September last year is a cousin of this story. Second instalment missed last year, interest.
Shortfall tool helps when you already paid something. Advance tax shortfall. Already paid vs what is usually due by this instalment. Guess. Then portal.

September week is a traffic jam
GSTR-1 around 11. EPF around 15. Advance tax 15. GSTR-3B around 20. I keep those on homepage cards in my head.
I dont pay advance tax from the GST cash ledger. Different logins. Different money.
School holiday week plus 15 September is bad if you travel. I pay before the picnic. Same habit as GST. School holiday week and GST due same week, plan. The article is GST but the picnic logic is the same.
Working days I count if 15th is a Sunday. Typical talk is next working day sometimes. I dont gamble. I pay on 13th or 14th. Working days calculator.
Portal hang on 15th night, screenshot helps, payment still needed. GST version of that panic: Portal hang on last date, screenshot enough. Income tax site can freeze too. Dont treat screenshot as challan paid.
Who is sweating 45 percent this month
Shop profit people. Freelance. Interest from FD that TDS did not fully cover. Two house rent. Capital gain if you sold something and you are guessing tax.
Salary only with heavy TDS, maybe not. Check the 10,000 leftover idea. Form 16 late is another mess. Form 16 not given, can I still estimate tax.
If taxable income just crossed basic exemption, filing later is one issue. Advance tax now is another. Taxable income more than basic exemption, now what.
Old vs new regime changes the tax cake. Estimate first. Old vs new regime estimate. FY label on that tool is an estimate only. Not a filed ITR.
If official later differs by 2,000, both can be honest. Why official tax and this calculator differ by 2,000.
Mistakes I still see in September
Paying 45 percent of profit, not of tax. That is a huge overpay. Man from MI Road did that. Refund waited. He was angry at me for not stopping him. I was not in the room.
Ignoring June and paying only 30 percent in September because “the gap is 30”. 45 minus 15 is 30 only if June was fully paid. If June was 5 percent, September needs to catch 45.
Using GST turnover as income. GST sales is not profit. Purchase and shop expense exist. I use a profit guess, not GSTR-1 total.
Paying from a friend’s account and forgetting PAN. Challan must talk to your PAN.
WhatsApp “extended till 20 September”. I dont trust 9 pm forwards. Official portal.
Skipping because ITR is in July next year. Advance tax is during the year. ITR is after. Two clocks.
What I keep ready on 14 September
PAN. Bank. Profit guess on paper. TDS certificates or AIS peek if I am brave. June challan.
Phone charged. Not shop wifi only. Income tax site is heavy.
If I already paid some, I still open Advance tax shortfall and Advance tax calculator. Two looks. One challan.
I file GST on different days so my brain does not mix challan passwords.
After payment I put CIN in the notebook. Same notebook as Tonk Road tea stains.
I am not the Income Tax Department. PayByDate is a helper. Dates are typical last published pattern, not law. If they move 15 September, look at the official portal, not my calendar sticker.
45 percent is the line that bites. Pay near it. Sleep. Shop opens tomorrow.
