fixed-price filing vs percentage-of-refund filing for tax filing in India
How a tax service charges you is not a small detail; it quietly shapes how your return gets filed. A fixed, published fee and a fee taken as a percentage of your refund pull in different directions, one towards a clear cost, the other towards a bigger refund. Both can be honest, and both can be abused. This guide compares them on the things that matter, so you can choose a model that is on your side.
- Fixed price: a set, published fee known before you start, the same whatever your refund.
- Percentage of refund: a share of any refund, pitched as "no refund, no fee".
- The incentive differs: fixed price rewards accuracy; a refund cut rewards a bigger refund.
- You carry the risk: a reversed refund is your liability plus interest, not the preparer's.
- Cost at scale: on a large refund, a percentage can cost many times a fixed fee for the same work.
- Third option: fixed price plus a verified CA and a review, as Claw Tax does, keeps clarity and adds accountability.
01The two models, defined
Strip away the marketing and there are two charging models in common use.
- Fixed-price filing. You pay a set, published fee for the return, known before you start, regardless of the refund. For example, a salaried ITR priced from a few hundred rupees.
- Percentage-of-refund filing. You pay nothing, or little, up front, and the service takes a share of any refund it obtains. The headline pitch is "no refund, no fee".
Both exist because they suit different sellers. The question is which suits you, and the answer turns on the incentive each creates.

02The incentive each creates
Follow the money, because the fee model decides what the preparer is paid to do.
- Fixed price rewards getting it done correctly. The fee is the same whatever the refund, so the preparer has no reason to inflate deductions. Their incentive is an accurate, defensible return and a satisfied repeat customer.
- Percentage of refund rewards a bigger refund. The larger the refund, the more the service earns. When the claims are genuine, that is fine. The danger is the pull towards aggressive or unsupported deductions, because a larger (even if risky) refund pays the preparer more.
This is the heart of the comparison. A refund you were not entitled to is your liability, not the preparer's. If a notice reverses it later, you repay the tax with interest, and possibly a penalty, while the preparer has already taken their cut. A fixed fee removes that conflict of interest entirely.
A percentage-of-refund fee pays someone more for a bigger refund. If that refund is later reversed, the cost falls on you, not on them.
03Cost compared with an example
On a small refund, a percentage can look cheap. On a large one, it can cost far more than a fixed fee for the same work. Consider two returns of similar complexity.
| Scenario | Fixed-price fee | Percentage-of-refund fee (illustrative 10%) |
|---|---|---|
| Refund of Rs 5,000 | Say Rs 499 | Rs 500 |
| Refund of Rs 50,000 | Say Rs 499 | Rs 5,000 |
| Refund of Rs 2,00,000 | Say Rs 2,499 (capital gains) | Rs 20,000 |
| No refund (tax payable) | Same published fee | Little or nothing, but no help either |
The percentages above are illustrative to show the shape, not any provider's actual rate; always check the real terms. The pattern is clear: the same preparation work can cost many times more under a percentage model when the refund is large, even though the effort did not change.
04Transparency and risk
Beyond cost, weigh clarity and exposure.
- Transparency. A fixed published price tells you the cost before you start. A percentage fee is only known once the refund is computed, and some models add conditions about what counts as the base.
- Who carries the risk. Under either model, you are legally responsible for the return. A fixed fee aligns the preparer with accuracy; a percentage fee can tempt overreach that you later have to defend.
- What happens with no refund. If you owe tax, a percentage model has little to charge and often little reason to engage, whereas a fixed-fee service does the same careful job regardless.
- Repeat trust. A fixed fee builds a service around doing it right every year; a refund cut builds it around maximising a number.
None of this means every percentage-of-refund service is dishonest. Many file legitimately. It means the model carries a conflict you should be aware of, and should ask about.
05A third option: fixed price plus a CA and a review
The two models are usually framed as the whole choice, but there is a third shape that keeps the clarity of fixed pricing and adds professional accountability: a fixed published fee, a verified chartered accountant who prepares and files, and a separate reviewer who checks the return before it is submitted.
This combination answers the main objection to cheap fixed-price tools (that no professional owns the work) and the main objection to percentage models (the conflict of interest), while keeping the cost visible up front.
06How Claw Tax helps
Claw Tax and Accounts is an online tax, GST and accounting service for India that connects you with a verified chartered accountant at a fixed, published price, with a Claw reviewer checking every filing before it is submitted.
Claw Tax uses the fixed-price model deliberately. You see the fee before you start, for example a salaried ITR from Rs 499 and a capital-gains ITR from Rs 2,499, and it does not change with your refund, so there is no incentive to inflate a claim. A verified partner CA prepares and files, a Claw reviewer checks the draft, and you approve before it is e-verified. That keeps the clarity of a fixed price and adds the accountability a bare self-file tool lacks. See the current service and prices at clawlaw.in/tax.

07Frequently asked questions
Is percentage-of-refund tax filing a good idea?
It can be fine when the claims are genuine, and it is attractive because you pay little up front. The catch is the incentive: the service earns more from a bigger refund, which can pull towards aggressive claims. Since a refund later reversed is your liability with interest, understand the model and ask how deductions are supported before choosing it.
Why is fixed-price filing considered safer?
Because the fee does not change with your refund, the preparer has no reason to inflate deductions, so their incentive is an accurate, defensible return. You also know the cost before you start. It removes the conflict of interest built into a refund-share model while keeping the price transparent.
Which is cheaper, fixed price or percentage of refund?
It depends on your refund. On a small refund a percentage can be cheaper than a fixed fee; on a large refund it is often much more expensive for the same preparation work. A fixed published fee is predictable and does not scale with the refund, which makes it easier to budget and usually better value when a sizeable refund is expected.
Who is responsible if a refund is reversed later?
You are. The return is filed in your name, so if an assessment reverses a refund, you repay the tax with interest and possibly a penalty, regardless of who prepared it or how they were paid. This is why the incentive created by the fee model matters, and why an accurate, reviewed return is worth more than a maximised one.
What should I ask before choosing a tax service by price model?
Ask what the total cost will be and when it is known, whether a qualified professional prepares and files the return, whether anyone reviews it before filing, and how any deduction or refund claim is supported. A service that answers these clearly, and prices transparently, is working with you rather than against you.
Does a fixed price mean no professional is involved?
Not necessarily. Some fixed-price options are bare self-file tools, but others pair a fixed published fee with a verified chartered accountant who prepares and files and a reviewer who checks the return. That third shape keeps the transparency of fixed pricing while giving you professional accountability.
