Advance Tax Under Presumptive Taxation: The Single Installment Privilege of 44AD and 44ADA

TL;DR

• Small businesses under Section 44AD and professionals under Section 44ADA enjoy a single advance tax installment due by 15 March of the financial year.
• The four-installment schedule (15 June, 15 September, 15 December, 15 March) does not apply to them.
• Section 44AD covers businesses with turnover up to Rs. 3 crore (raised from Rs. 2 crore when 95 percent of receipts are digital).
• Section 44ADA covers specified professionals (doctors, lawyers, CAs, architects, engineers, IT consultants) with gross receipts up to Rs. 75 lakh.
• The presumed profit is 8 percent of turnover (6 percent for digital receipts) under 44AD, and 50 percent of gross receipts under 44ADA.
• Missing the 15 March deadline still attracts Section 234C interest at 1 percent on the shortfall for one month.

What this means in plain terms

The presumptive taxation scheme exists because the income tax department recognises that small businesses and independent professionals cannot maintain books with the same rigour as large companies. So instead of asking for detailed income, expense, and depreciation accounting, the law lets them declare a presumed percentage of turnover as profit and pay tax on that. It is simpler, faster, and audit-free.

The advance tax concession is the second leg of the same simplification. Asking a small kirana owner or a freelance designer to estimate quarterly income and deposit four installments would defeat the purpose. So the law collapses the four installments into one, due by 15 March. You pay the full estimated annual tax in one go, just two weeks before the financial year ends, and that satisfies Section 211 of the Income Tax Act, 1961.

How Section 44AD works for small businesses

Turnover and presumed profit

Section 44AD applies to resident individuals, HUFs, and partnership firms (other than LLPs) carrying on a business with turnover up to Rs. 3 crore in FY 2025-26, provided that at least 95 percent of receipts are through banking channels or prescribed digital modes. For cash-heavy businesses, the limit is Rs. 2 crore. The presumed profit is 8 percent of turnover, or 6 percent if receipts are digital.

Eligibility limits and lock-in

The Rs. 3 crore limit is generous and covers most small traders, manufacturers, and service businesses. However, if you opt for 44AD and then in a future year claim lower profits with regular books, you are locked out of 44AD for five subsequent years. So the choice is sticky.

Not available to specified categories

Section 44AD is not available for professionals covered under Section 44ADA, agency businesses, commission-based businesses (insurance agents, for example), and businesses earning income from plying or hiring goods carriages (which has its own Section 44AE).

How Section 44ADA works for professionals

Eligible professions

Section 44ADA covers specified professions notified under Section 44AA(1) — legal, medical, engineering, architectural, accountancy, technical consultancy, interior decoration, film artists, and IT professionals (added later by CBDT notification). Gross receipts must not exceed Rs. 75 lakh in FY 2025-26 (raised from Rs. 50 lakh when 95 percent of receipts are digital).

Presumed profit at 50 percent

Half of gross receipts is presumed as profit, and the remaining half is treated as expenses. If your actual margin is higher (say, 70 percent because you have low overheads), 44ADA is hugely beneficial — you pay tax only on 50 percent. If your actual margin is lower, you can opt out, but you then need to maintain books and may face audit under Section 44AB.

Tax computation

The 50 percent presumed profit is added to other income (salary, interest, capital gains) and taxed at slab rates. So for a doctor with Rs. 60 lakh gross receipts and Rs. 10 lakh salary, the taxable income is Rs. 30 lakh (50 percent of Rs. 60L) plus Rs. 10 lakh salary, less applicable deductions.

The single-installment rule

Section 211 proviso

The proviso to Section 211(1) explicitly states that for an assessee who declares income under Section 44AD or 44ADA, the entire amount of advance tax is payable by 15 March of the financial year. There is no 15 June, 15 September, or 15 December obligation.

How interest under 234C is computed

If the presumptive taxpayer pays less than 100 percent of the assessed tax by 15 March, Section 234C charges 1 percent simple interest for one month on the shortfall. The 234B interest from 1 April onwards continues to apply if total advance tax plus TDS is below 90 percent of assessed tax.

Self-assessment tax for residual

Any shortfall after the 15 March deadline is paid as self-assessment tax using Challan 280 with minor head 300 before filing the ITR.

Practical considerations for presumptive taxpayers

Keep a turnover tracker

Even though books are not mandatory under 44AD, you still need to know your turnover to compute the presumed profit. Maintain a simple tracker — invoices issued, payments received, bank deposits — to estimate the 8 percent or 50 percent figure accurately by February each year.

Watch the Rs. 75 lakh and Rs. 3 crore thresholds carefully

If turnover crosses the limit even by a small margin, you fall out of presumptive taxation for that year and need to maintain books and possibly undergo audit under Section 44AB. Plan invoicing in March to stay within the threshold if you are close.

TDS coverage

Clients paying you professional fees deduct TDS at 10 percent under Section 194J. Bank interest above Rs. 40,000 has 10 percent TDS under Section 194A. Compute residual advance tax by deducting this TDS from your estimated total tax.

A real example

Pooja, 36, freelance UX designer, Bengaluru, has gross receipts of Rs. 42 lakh from clients in FY 2025-26 (95 percent through bank transfers). She also earns Rs. 1.8 lakh FD interest and has Rs. 4 lakh long-term capital gains from selling old mutual funds in November 2025.

Her tax workout under Section 44ADA:

1. Gross receipts Rs. 42L. Presumed profit at 50 percent = Rs. 21L.
2. Add FD interest Rs. 1.8L. Add LTCG Rs. 4L (Rs. 2.75L taxable above the Rs. 1.25L Section 112A threshold).
3. Total taxable income (excluding LTCG): Rs. 21L + Rs. 1.8L = Rs. 22.8L.
4. Under the new regime with Rs. 75,000 standard deduction (not applicable on professional income) — but she gets it on the salary head only if she had salary. Tax on Rs. 22.8L approximates Rs. 3,90,000 plus 4 percent cess = Rs. 4,05,600.
5. LTCG tax at 12.5 percent on Rs. 2.75L = Rs. 34,375 plus cess = Rs. 35,750.
6. Total tax: Rs. 4,41,350.
7. TDS deducted by clients under 194J (10 percent on Rs. 42L) = Rs. 4,20,000. Bank TDS on FD interest (10 percent on Rs. 1.8L) = Rs. 18,000. Total TDS = Rs. 4,38,000.
8. Advance tax obligation: Rs. 4,41,350 minus Rs. 4,38,000 = Rs. 3,350.

Because her residual is below Rs. 10,000, technically Section 208 says she is not even liable for advance tax. But the more common scenario is that TDS only partially covers the liability. Suppose her clients deducted only Rs. 2,80,000 (because some did not deduct). Her residual would be Rs. 1,38,350, payable in one shot by 15 March 2026. She uses Challan 280 with minor head 100 (Advance Tax) on incometax.gov.in.

FAQ

Can I pay in four installments anyway even though I am eligible for the single installment?

Yes, voluntarily. Some presumptive taxpayers prefer the four-installment route to smooth cashflow. The law gives you the option but does not force the single-installment route. As long as 100 percent is paid by 15 March, you are clean.

What if I cross the Section 44ADA limit of Rs. 75 lakh mid-year?

You then need to opt out of 44ADA for that year, maintain books under Section 44AA, get audited under Section 44AB, and pay advance tax in the regular four-installment schedule. This catches many growing freelancers by surprise.

Does my advance tax depend on the presumed profit or actual profit?

It depends on the income you will declare — which under 44AD/44ADA is the presumed profit. Even if actual is lower or higher, advance tax is computed on the presumed figure (8 percent, 6 percent, or 50 percent as applicable).

I am a partner in an LLP — can I use 44AD?

No. Section 44AD is available only to resident individuals, HUFs, and partnership firms (not LLPs). LLPs and their partners need to use regular accounting.

What if my client deducts TDS but I declare under 44ADA?

You claim full TDS credit in your ITR regardless of which scheme you choose. TDS credit and presumptive taxation are independent — TDS reduces your advance tax obligation, the scheme decides how income is computed.

Does the single-installment rule apply if I have salary income too?

Yes, but only on the presumptive income piece. If you have salary with full TDS coverage and additional 44ADA income, the residual on the 44ADA portion can be paid in one installment by 15 March. If you have other non-presumptive income that itself requires advance tax, that portion may need installments.

Can I opt out of presumptive taxation any year?

Yes, but under Section 44AD, opting out triggers a five-year lockout from re-entering 44AD. Section 44ADA does not have an equivalent lock-in. The choice should be deliberate.
