The payroll mistakes worth writing about are not the ones where somebody typed 5,000 instead of 50,000. Those get caught the same day, by the employee.
The expensive ones are structural. They are applied correctly and consistently every month, they look right on the register, and they are only visible when an inspector, an auditor or a departing employee looks at them from a different angle. By then they have been repeating for two years, and the arrears come with interest attached.
Mistake 1: Building the salary structure to minimise PF
The pattern is familiar. Basic pay set at 30 or 35 per cent of gross, with the rest distributed across special allowance and a few reimbursements, so that provident fund on basic plus dearness allowance stays small.
It works until it does not. Provident fund authorities have consistently taken the position that allowances paid universally to all employees form part of wages for contribution purposes, and that a structure engineered to suppress the base can be looked through. When that view is applied to your structure, the exposure is retrospective contributions for both shares, plus interest and damages, for every employee and every month it ran.
The Code on Wages, when it comes into force, tightens this further by defining wages so that the excluded components cannot exceed half of total remuneration. Companies that have kept basic at a third of gross will have to restructure, and doing it before the deadline is considerably easier than doing it under one.
A structure designed around a statutory minimum tends to break the first time the statute moves. Design it around what the role is paid, and let the contributions fall where they fall.
Mistake 2: Calling an employee a consultant
Someone works full time, reports to a manager, keeps your hours, uses your systems, and raises a monthly invoice for a fixed amount. On paper they are a consultant, so there is no provident fund, no ESI, no gratuity accrual and tax is deducted under Section 194J instead of Section 192.
Classification is decided on the substance of the relationship rather than on the label in the contract. Control over how the work is done, integration into the organisation, fixed hours and exclusivity all point one way. If the authorities or a tribunal take that view, the liability is retrospective PF and ESI on both shares, with interest and damages, and potentially gratuity for anyone who has crossed five years.
There are legitimate consultants, and the test is not whether you call them one. It is whether you would still describe the arrangement as independent if you had to explain it to someone who could see how the person actually works.
Mistake 3: Missing the minimum wage revision
Minimum wages are notified by each state, by category of employment, skill level and sometimes zone within the state. The variable dearness allowance component is revised periodically, commonly twice a year, and the revision does not arrive as an email addressed to you.
Paying below the notified minimum is an offence regardless of what the employee agreed to, and consent is not a defence. Companies with staff in several states are the most exposed, because a revision in one state is easy to miss while everyone is looking at a different one. The check is straightforward: for each state and each category, compare the lowest wage you pay against the current notification, every six months.
Mistake 4: Deducting professional tax on the wrong state
Professional tax follows where the employee works. Payroll systems tend to follow where the company is registered, because that is what was configured on day one.
The result is a company headquartered in a state that levies professional tax deducting it from employees working in Delhi or Haryana, where there is no levy at all, or the reverse: staff in Bengaluru with nothing deducted because head office is in Gurugram. The first is money taken from employees that should not have been. The second is a liability sitting with the employer, since it is the employer who is answerable for the deduction, with interest and a penalty per return.
Mistake 5: Getting PF and ESI eligibility wrong at joining
Both schemes decide coverage at a point in time, and both are easy to get wrong in the same direction.
For provident fund, the ₹15,000 basic and dearness allowance ceiling applies at the time of joining. Someone hired above it can be treated as an excluded employee, but someone already a member stays a member after a raise. Excluding an existing member because their salary crossed the ceiling is a straightforward error and a common one.
For ESI, coverage is tested at the start of a contribution period and holds for the whole period. When a raise takes someone past ₹21,000 in July, contributions continue on the higher wage until 30 September. Stopping in July creates a shortfall that ESIC will ask for, and the employee may have made a claim in the meantime on the strength of contributions you stopped paying.
Mistake 6: Leaving TDS until March
Tax deducted at source on salary is meant to be spread across the year on a projection that gets refreshed as facts change. What happens in practice is that declarations are taken in April, nobody looks at them again, proofs are collected in January or February, and the entire correction lands in the last month or two of the year.
The consequences are predictable. An employee whose declared investments never materialised sees most of a month's salary disappear in March. Anyone who joined mid-year without their previous employer's income on Form 12B has been under-deducted all year, and the shortfall is theirs to settle at filing. Bonuses paid in December change the projection for the rest of the year, and nobody was told.
Refresh the projection after every revision, bonus, joiner and exit. The arithmetic is the same either way, and the difference is whether the employee sees it coming.
Mistake 7: Paying people outside the payroll run
An advance, an incentive, a settlement, a small correction. A transfer goes out from the finance account and payroll finds out later, or does not.
Every one of those breaks three things at once. It does not enter the TDS projection, so the year-end tax is wrong. It does not form part of the PF or ESI base where it should, so the contributions are short. And it does not reach the salary register, so the accounting entry and the annual reconciliation stop tying. Six of them across a year is enough to make the Form 24Q reconciliation fail, which then shows up as a mismatch between the employee's Form 16 and their 26AS.
The rule is simple even when the payment is urgent: anything paid to an employee for their employment goes through the register, even if the money moves before the run.
Mistake 8: Missing statutory due dates
Four authorities, four dates, and the fines are not the expensive part.
| What is late | Due date | What it costs |
|---|---|---|
| TDS deducted but not deposited | 7th of the following month | Interest at 1.5 per cent per month from the date of deduction |
| TDS not deducted at all | 7th of the following month | Interest at 1 per cent per month, plus penalty exposure |
| Provident fund contribution | 15th of the following month | Interest at 12 per cent a year, plus damages levied separately |
| ESI contribution | 15th of the following month | Interest at 12 per cent a year, plus damages |
| Form 24Q quarterly return | 31 July, 31 Oct, 31 Jan, 31 May | Late fee per day until filed, and employee 26AS mismatches |
The Form 24Q row is the one people underestimate. A late or incorrect return does not just carry a fee. It means the tax you deducted does not appear in the employee's 26AS, so their return does not match, and the queries land on HR in July when the person responsible has usually moved on to something else.
Mistake 9: Treating full and final as a low-priority queue
Settlements slip because they are nobody's deadline. The manager has not confirmed the asset return, finance is waiting on the manager, and the ex-employee has no leverage other than following up.
Most companies target 30 to 45 days, and gratuity where payable has a 30-day clock of its own from the date it becomes payable, with interest where it is delayed beyond that. Beyond the compliance point, this is the single most common reason a reasonably amicable exit turns into a public complaint, and the delay is almost never about money. It is about one confirmation nobody chased.
Withholding a settlement as leverage for something else, an unreturned laptop or an unserved notice period, is a separate and worse version of the same mistake. Recover what is due through the settlement, with the deduction shown, rather than holding the whole amount.
Mistake 10: One person owning payroll end to end
In smaller companies one person usually does all of it: maintains employee master data, changes bank accounts, runs the calculation, generates the bank file and releases it. This is rarely a trust question and always a control question.
The exposure is not only fraud, though payroll diversion is common enough to be worth naming: a bank account changed on a request that arrived by email, with the salary going out for two months before anyone notices. The more frequent exposure is that a single error has no second pair of eyes anywhere in the chain, and the same person who made it is the one checking it.
Separate at least one link. Someone other than the person running payroll approves master data changes, or approves the final register, or releases the bank file. Verify bank account changes through a channel other than the one the request came in on. None of that requires headcount, and it is the cheapest control on this list.
The mistakes that only surface once a year
Some errors are invisible monthly and obvious annually, which is why the annual reconciliation deserves more attention than it gets.
- The TDS ledger not tying to the challans, discovered when Form 24Q is filed and the numbers do not agree
- Form 16 figures not matching the employee's 26AS or AIS, usually caused by a wrong PAN or an off-cycle payment
- PF and ESI liability accounts carrying balances that nobody has explained since the middle of the year
- Leave and gratuity provisions never trued up against the actual liability, understating cost for four quarters
- Statutory bonus not paid to eligible employees within eight months of the accounting year closing, under the Payment of Bonus Act
A quarterly reconciliation of each statutory ledger to what was actually paid takes an hour and removes most of that list.
Frequently asked questions
What is the most common payroll mistake?
Structuring salary to keep basic pay low so provident fund contributions stay small. It is applied consistently, looks correct on every payslip, and creates retrospective exposure across every employee and every month it ran.
What is the penalty for late PF payment?
Interest at 12 per cent a year on the amount due, with damages levied separately by EPFO on top. ESI works the same way. Confirm current damages rates with the authority, since they have been revised.
What happens if TDS is deducted but not deposited on time?
Interest runs at 1.5 per cent per month from the date of deduction to the date of payment. Where tax was not deducted at all, interest is 1 per cent per month, and there is penalty exposure on top.
Can we hire full-time staff as consultants to avoid PF and ESI?
Classification is judged on how the work is actually controlled, not on the contract label. Someone working fixed hours under your direction, integrated into your team, is likely to be treated as an employee, with retrospective PF and ESI on both shares plus interest and damages.
How should an overpayment to an employee be corrected?
Tell the employee, agree a recovery schedule in writing, and stage it across months so total deductions stay within the 50 per cent ceiling under the Payment of Wages Act. Recovering it in one month without notice is where disputes start.
Which state's professional tax should be deducted?
The state where the employee works, not the state the company is registered in. Deducting on the head office state leaves the employer liable for the correct amount with interest and a penalty per return.
When is statutory bonus payable?
Within eight months of the close of the accounting year, to employees whose wages are within the eligibility limit under the Payment of Bonus Act, at a minimum of 8.33 per cent.
How do we stop payroll fraud in a small team?
Separate one link in the chain. Have someone other than the payroll operator approve master data changes or release the bank file, and verify every bank account change through a different channel than the one the request arrived on.
Read back through the ten and most of them share a shape. They are decisions taken once, usually for a defensible reason at the time, and then never revisited while the circumstances changed around them. The audit worth running is not a search for errors in last month's register. It is a look at the assumptions the register has been built on since the year you set it up.
