Presumptive Taxation Calculator

What Presumptive Taxation Actually Does

Instead of computing your real profit (receipts minus actual expenses) and maintaining books of accounts to prove it, presumptive taxation lets you declare a fixed percentage of your turnover as "deemed" taxable income and stop there — no books, no expense substantiation, no audit requirement in most cases. Section 44AD covers eligible businesses (6% of digital/banking receipts, 8% of cash receipts); Section 44ADA covers eligible professionals (50% of gross receipts, flat, regardless of payment mode).

This is worth it when your real expense ratio is lower than the deemed percentage — you end up taxed on less income than you'd actually report under normal provisions. It works against you if your genuine expenses are unusually high relative to turnover, since presumptive taxation doesn't let you deduct them.

Worked Example

A business with ₹20,00,000 in digital/banking receipts, ₹5,00,000 in cash receipts, and ₹4,00,000 in actual expenses:

The presumptive income here (6% of ₹20L + 8% of ₹5L = ₹1.6L) falls well below the ₹12 lakh new-regime rebate threshold, so tax is zero under the presumptive route — while the same turnover taxed on actual net income (₹25L receipts − ₹4L expenses = ₹21L) pushes well into taxable territory. This gap is exactly why presumptive taxation is attractive for businesses whose real expenses are modest relative to turnover.

Eligibility Isn't Just "Pick the Lower Number"

Presumptive taxation under 44AD is available only if your total turnover is within the prescribed limit — a higher limit applies if at least 95% of your receipts are through banking channels rather than cash. Section 44ADA has its own, separate turnover ceiling for professionals. Opting in or out also has consequences beyond a single year: switching out of the presumptive scheme after using it can restrict your ability to use it again for several years, and businesses with income below the deemed percentage who still want to opt out entirely may face a tax audit requirement. This calculator compares the tax outcome only — it doesn't check turnover eligibility or these switching consequences, so confirm both before deciding.

Digital vs Cash Receipts: Why the Split Matters for Business Income

For businesses, the deemed presumptive income rate is lower for receipts through banking or digital channels than for cash receipts — the calculator above applies a lower rate to the digital-receipts figure you enter and a higher rate to the cash-receipts figure, then adds the two deemed amounts together. This reflects a policy preference for traceable, banked transactions over cash. It also means the same total turnover can produce a meaningfully different deemed income depending on how much of it moved through banking channels versus cash — a business collecting entirely digitally reports a lower presumptive income on the same turnover than one collecting mostly in cash.

Professionals under the professional-income route don't have this split — the deemed percentage is a single flat rate applied to total gross receipts regardless of payment mode.

The professional rate is deliberately much higher than the business rates, since professional services generally carry lower input costs relative to fees billed compared to a trading or manufacturing business's cost of goods.

What Happens Once You Opt In

Opting for presumptive taxation simplifies your compliance considerably — no requirement to maintain detailed books of accounts or, in most cases, get them audited, since your declared income is a fixed percentage of turnover rather than a computed profit figure. But you still need to maintain basic records of receipts to support the turnover figure you're declaring, and you still file an income tax return each year reporting this deemed income. If you believe your actual profit is lower than the deemed percentage and want to declare that lower actual figure instead, you can, but doing so typically brings back the requirement to maintain books of accounts and undergo an audit — so the simplification only holds as long as you're comfortable declaring at or above the deemed rate.

Who Qualifies as "Eligible" for Presumptive Taxation

Not every business or professional automatically has access to these schemes. The business presumptive route is generally available to resident individuals, HUFs, and partnership firms (other than LLPs) carrying on an eligible business — certain businesses, such as those involving commission or brokerage, and the plying, hiring, or leasing of goods carriages (which have their own separate presumptive scheme), are excluded from this particular route. The professional route is limited to specified professions — commonly including legal, medical, engineering, architectural, accountancy, technical consultancy, interior decoration, and a few other notified categories — rather than being open to any self-employed person describing themselves as a professional.

Because the exact list of eligible and excluded categories has been refined over time through amendments and notifications, confirm your specific business or professional category is currently covered before assuming eligibility, rather than relying on a general description of your work.

Advance Tax Under the Presumptive Scheme

One further compliance simplification under presumptive taxation is on advance tax: taxpayers opting for the business presumptive scheme generally need to pay their entire estimated advance tax liability for the year in a single instalment rather than the multiple quarterly instalments that regular taxpayers follow — check the current due date for this single instalment, since paying late still attracts interest even though the number of instalments is reduced. The professional presumptive route's advance tax treatment can differ from the business route's, so don't assume the same single-instalment rule automatically carries over — verify which schedule applies to your specific situation before your first advance tax payment of the year.

What Happens If You Opt Out After Using the Scheme

The eligibility rules aren't purely forward-looking — how you used presumptive taxation in the past can restrict your options going forward. If you opt for the business presumptive scheme in one year and then declare income under regular provisions in a later year (without your turnover exceeding the eligibility limit), you can generally lose the ability to opt back into the presumptive scheme for several subsequent years, and may also be required to maintain full books of accounts and undergo an audit for those years even if you would otherwise have qualified. This asymmetry — easy to opt in, restrictive to opt back in after voluntarily opting out — is worth weighing before treating presumptive taxation as a switch you can flip freely year to year based on which route saves marginally more tax in any given year.

Presumptive Taxation for Non-Resident Shipping, Air Transport, and Similar Businesses

Beyond the general business and professional routes covered by this calculator, tax law also carries separate, narrower presumptive schemes for specific categories — non-resident shipping and air transport businesses, foreign companies engaged in certain turnkey power projects, and businesses providing services or facilities in connection with the extraction of mineral oils, among others. Each of these has its own deemed-income percentage and its own conditions, distinct from the general business and professional schemes this page focuses on. If your income falls into one of these specialised categories rather than ordinary trading, manufacturing, or professional-service income, this calculator's general rates won't apply — the specific scheme for your category needs to be checked separately.
