Calculate salary arrears, estimated tax impact, Section 89(1) relief and net arrear payout in India. Use this free arrear salary calculator to understand whether a delayed increment, DA revision, promotion arrear, 7th Pay Commission arrear, pension arrear or company salary revision can increase your tax and how Form 10E relief may reduce the burden.
Enter your current taxable income excluding arrears, the arrear amount received this year, and the previous years to which the arrear relates. The calculator estimates the additional tax in the year of receipt and compares it with the additional tax that would have applied if the arrear had been taxed in the relevant past years.

A salary arrear is not just an extra payment. For tax purposes, it can push your income into a higher slab in the year you receive it. That is why a simple “arrear amount minus TDS” calculation is often incomplete. This page is built for Indian salaried employees, government employees, PSU employees, pensioners, HR teams and payroll users who want to estimate the real tax effect of arrears and understand how relief under Section 89(1) works.
Use it when your employer revises salary from a back date and pays the difference in one month. This is common after annual appraisal delays, promotion approvals, designation corrections or salary restructuring.
Government and PSU employees often receive DA arrears, pay commission arrears, grade pay corrections or pension revision arrears. A year-wise split helps estimate Section 89 relief.
The calculator mirrors the broad logic of Form 10E: compare tax on current income with and without arrears, then compare tax for the past years with and without the allocated arrears.
It estimates how much arrear remains after additional tax and any TDS already deducted. This helps users understand whether the credited amount on salary slip looks reasonable.
Salary arrear means salary that should have been paid in an earlier period but is paid later. It may happen because an increment was approved late, a promotion was effective from a past date, dearness allowance was revised, pay scale was corrected, bonus was reclassified as salary, or payroll missed a component for previous months. In simple words, arrears are “past salary paid now”. The amount may appear in a salary slip as arrear basic, DA arrear, HRA arrear, special allowance arrear, overtime arrear, leave salary arrear, pension arrear, or revised pay arrear.
For employees, the first question is usually: “How much arrear will I get in hand?” The second question is more important for tax: “Will this arrear increase my tax slab?” Since India has progressive income tax rates, a lump sum paid in one financial year may increase the average tax rate for that year. A person whose normal taxable income is ₹8 lakh may receive ₹3 lakh arrears and suddenly appear to have ₹11 lakh taxable income in the receipt year. The arrear belongs partly to earlier years, but tax is generally deducted when paid unless relief is claimed correctly.
This is where an arrear salary calculator becomes useful. It does not only multiply monthly difference by number of months. It also separates the amount into the year in which it was due and estimates whether Section 89(1) relief can reduce the extra tax. For payroll teams, this also helps explain why TDS on arrears may look high in one month. For employees, it helps prepare Form 10E, check salary slips, and plan tax declarations before filing the income tax return.
The basic salary arrear formula is simple when you only want the gross arrear amount. However, the taxable arrear and in-hand arrear depend on deductions, TDS, PF and the year to which the payment relates. A clean approach is to calculate the monthly difference component-wise and then add the applicable months.
For example, if your basic salary was revised from ₹45,000 to ₹50,000 per month from April, but the revision was paid in October, the basic arrear for April to September is ₹5,000 × 6 = ₹30,000. If HRA is linked to basic salary, HRA arrear may also arise. If provident fund is calculated on basic salary, PF may also change. If the arrear is taxable, TDS can be deducted by the employer when arrear is paid.
A good arrear calculation should not mix gross arrear and net arrear. Gross arrear is the employer’s total payable salary difference before statutory deductions. Net arrear is the amount likely to reach your bank account. Tax relief under Section 89 does not make arrears non-taxable; it only reduces hardship when tax is higher because several months or years of income are received in a single financial year.
Section 89(1) is designed for situations where salary, family pension or certain employment-related payments are received in arrears or advance and the lump sum causes the income to be assessed at a higher rate. In practical terms, it allows the tax impact to be compared with the tax that would have applied if the salary had been received in the year to which it actually related.
The relief calculation compares two numbers. First, calculate the extra tax in the year of receipt by adding arrears to the current year income. Second, calculate the extra tax in the relevant past year or years by adding the allocated arrears to those years. If the current-year extra tax is higher than the total past-year extra tax, the difference is relief. If the current-year extra tax is lower or equal, there may be no relief.
This is why year-wise details matter. A single arrear amount of ₹2 lakh may relate to one year, two years or three years. If it relates to multiple years, it should be split according to the period for which it was due. A DA arrear may be spread month-wise over several months. A pay revision arrear may be split from the effective date of revision. A pension arrear may be allocated to the financial years for which pension was due.
Section 89 relief is especially relevant for government employees, retired employees, pensioners, teachers, bank employees, railway employees, defence pensioners, PSU workers and corporate employees whose increments or variable salary were approved late. It is also relevant when an employee changes jobs and receives arrears from a former employer. The tax return should still include the arrear as salary income, but relief may reduce the final tax payable if Form 10E is filed properly.
Suppose an employee’s monthly CTC component increases by ₹12,000 from April, but the employer pays the revised salary only from October. The arrear for April to September is ₹12,000 × 6 = ₹72,000. If the employee’s taxable income excluding arrears is ₹9,00,000 and arrear is received in the same financial year, the current year tax must be calculated on ₹9,72,000. If the arrear belongs to the same year only, Section 89 relief may not be relevant because the arrear does not relate to a previous financial year.
Assume an employee receives ₹1,80,000 in April 2026 for a salary revision effective from April 2024 to March 2026. If ₹90,000 belongs to FY 2024-25 and ₹90,000 belongs to FY 2025-26, the calculator compares the extra tax in the year of receipt with the extra tax that would have arisen in FY 2024-25 and FY 2025-26 after adding the allocated arrears. If the current year slab impact is higher, Section 89 relief may be available.
A pensioner may receive revised pension arrears after a delayed pension order or family pension correction. The lump sum may cover many months and can increase the taxable income of the receipt year. The pensioner can use the same principle: allocate arrear to the relevant financial years, calculate tax with and without the arrear in each year, and claim relief through Form 10E if eligible.
Form 10E is the form used to furnish particulars for claiming relief under Section 89. It is generally filed online on the income tax e-filing portal before filing the income tax return. If a taxpayer claims Section 89 relief in the return but does not file Form 10E, the relief may not be allowed during processing. That is why employees should not wait until the last minute if they have significant arrears.
Form 10E usually requires details such as amount received in arrears or advance, relevant previous years, total income of those years excluding arrears, tax calculation for those years, and the relief amount. Your employer may provide an arrear statement, month-wise breakup or Form 16 details, but the final responsibility for return filing and relief claim remains with the taxpayer. If the arrear is large or relates to multiple years, consult a tax professional before filing.
Many users confuse Form 10E with Form 16. Form 16 is issued by the employer as a TDS certificate. Form 10E is filed by the taxpayer for relief. An employer may consider Section 89 relief while deducting TDS if the employee submits the required details, but this does not replace the need to ensure correct return filing. Always retain the employer’s arrear worksheet, payslip, old salary structure, revised salary letter and Form 16.
Employers deduct TDS on salary based on estimated taxable salary for the year. When arrears are paid, the employer may add the arrear to annual salary and deduct additional tax in the payment month. This can make one month’s salary look unusually low. The deduction is not always an error; it may be the result of the arrear pushing annual income into a higher slab.
If the employer has deducted high TDS on arrears, the taxpayer may still get relief or refund at the time of return filing, provided the conditions are met and Form 10E is filed. On the other hand, if the employer deducted less TDS, the taxpayer may have to pay self-assessment tax while filing the return. The calculator’s “TDS already deducted” input helps estimate whether the expected net arrear is close to the bank credit.
Remember that TDS is not final tax. It is only tax deducted in advance. Final tax depends on the full income, deductions, regime selection, arrear allocation, Section 89 relief, surcharge if applicable, and cess. That is why the tax shown on salary slip may differ from the final tax in the income tax return.
New and old regime selection can affect the tax on arrears. The new regime generally has lower slab rates and fewer deductions. The old regime allows deductions and exemptions such as HRA, 80C, home loan interest and other eligible deductions, subject to conditions. For arrear relief, the tax computation should align with the regime used for the relevant year. If the previous years used old regime and the current year uses new regime, the actual Form 10E computation may require careful year-wise treatment.
This page keeps the calculator simple by applying the selected regime for the estimate. It is suitable for planning and understanding the direction of relief. For final filing, taxpayers should use exact year-wise data. The final Form 10E should match the income tax return, Form 16, AIS/TIS data and employer statement.
Before claiming relief, collect all relevant documents. You may need salary slips for arrear month, revised salary letter, old salary structure, promotion letter, DA revision circular, arrear calculation sheet, month-wise breakup, Form 16, previous year income details, tax computation statements and proof of deductions. If arrear is from a former employer, keep communication and TDS certificate from that employer as well.
For government employees, the arrear statement may be generated through payroll systems. For corporate employees, HR or finance may issue a one-page arrear note. If the arrear statement does not split the amount by financial year, ask payroll for a year-wise or month-wise breakup. Without a proper split, Form 10E relief calculation becomes difficult and may be inaccurate.
The first mistake is calculating only gross arrears and ignoring tax. A ₹2,00,000 arrear does not always mean ₹2,00,000 in hand. The second mistake is assuming every arrear qualifies for relief. If the arrear belongs to the same year, Section 89 may not reduce tax. The third mistake is not filing Form 10E before claiming relief in the return. The fourth mistake is using the wrong income figure for previous years. You should use taxable income and correct deductions, not only gross CTC.
Another common mistake is ignoring TDS already deducted. If employer has already deducted tax, the net bank credit may look lower but final refund may be possible after return filing. Some users also confuse arrear with bonus. Bonus is generally taxable in the year it is received unless it clearly relates to past salary and meets conditions for relief. When in doubt, classify the payment correctly before using a calculator.
This salary arrear calculator is useful for salaried employees in India, HR teams, payroll executives, finance teams, government employees, PSU employees, bank employees, teachers, IT professionals, pensioners and family pension recipients. It is also useful for people who receive backdated increments after changing companies, delayed full-and-final settlements, pay commission arrears, DA arrears, revised pension arrears or arrears from a former employer.
The tool is especially helpful when you want to answer search questions such as salary arrear calculator India, arrear salary tax calculator, Section 89 relief calculator, Form 10E calculator, salary arrears tax relief, how to calculate arrears in salary, arrear salary taxable or not, arrear salary in hand calculator, salary revision arrear calculator, and income tax relief on salary arrears.
This page is optimized for human readers and semantic search intent around arrear salary, tax relief, payroll arrears and Form 10E.
Start with the income figure that will appear in your return before adding arrears. Many people enter gross CTC here, which can distort the result. For a cleaner estimate, use taxable income after standard deduction, eligible deductions, professional tax and other adjustments that are already part of your normal tax computation. Then enter the arrear amount that is taxable as salary. If your payslip shows separate components such as basic arrear, DA arrear, HRA arrear and special allowance arrear, add only the taxable portion that should be included in salary income.
The most important part is the year-wise allocation. Do not simply divide the arrear equally unless the arrear actually accrued equally over those years. A salary increment arrear generally follows the monthly effective date of the increment. A DA arrear may follow the DA notification period. A pension arrear may follow the revised pension order. A promotion arrear may start from the backdated promotion order. A grade correction may relate to the period for which the wrong grade was applied. The closer your year-wise split is to the employer statement, the more useful the estimate becomes.
After entering the data, read three numbers carefully. “Additional tax before relief” shows the tax impact if the entire arrear is taxed in the receipt year. “Estimated Section 89 relief” shows the amount that may reduce the burden if spreading the arrear to past years produces a lower tax impact. “Estimated net arrear after tax and TDS” gives a rough in-hand amount after adjusting the additional tax and any TDS already deducted. These numbers are planning estimates, not a substitute for the final return utility.
Payroll arrears and income tax arrears are different concepts. Payroll arrears mean the employer owes salary for an earlier period. Income tax arrears usually mean unpaid tax demand or outstanding tax liability. This page deals with payroll salary arrears and their tax treatment. When an employer pays salary arrears, the amount becomes part of salary income. If tax is deducted, it appears in Form 16 and Form 26AS/AIS depending on reporting. If the employer does not deduct enough tax, the employee may still be liable to pay tax while filing the return.
Another related term is “arrear recovery”. Sometimes salary slips show arrear earnings on one side and recoveries on the deduction side. Recoveries may include excess salary recovery, PF arrear, NPS arrear, professional tax adjustment, loan recovery or TDS. Always separate gross earnings from recoveries. A tax calculator should generally use taxable salary arrears, while an in-hand calculator should also consider recoveries that reduce the bank credit.
Salary arrears may affect multiple components. If basic salary is revised, dearness allowance, HRA, provident fund, gratuity valuation and some allowances may also change depending on the salary structure. For a government employee, DA arrears can be a major component and may be paid after official approval. For private employees, arrears may come from annual increment delays, joining bonus corrections, variable pay reclassification or salary restructuring. For pensioners, arrears may come from pension revision, family pension correction or commutation adjustments.
PF treatment depends on the payroll policy and statutory wage basis. If PF arrears are deducted, the net arrear credited to the bank can be lower than the gross arrear. NPS arrears may also be deducted for some government employees or employer policies. HRA arrears may be taxable or exempt depending on old regime conditions, actual rent, salary definition and documentation. The calculator keeps the tax relief estimate focused on taxable income, so users should enter the amount after deciding what part of the arrear is taxable.
Relief can be significant when the arrear pushes the current year income into a much higher slab, but the relevant past years had lower income or lower tax impact. For example, an employee who has now moved into a higher salary band may receive arrears relating to earlier years when the income was lower. If the full arrear is taxed today, the extra tax may be higher than the tax that would have applied in those earlier years. Section 89 attempts to reduce this mismatch.
Relief may be low or zero when the arrear does not change the slab significantly, when the past years would have produced similar or higher additional tax, or when the arrear relates only to the current year. Relief also depends on deductions and exemptions used in each year. That is why two employees receiving the same arrear can have different relief amounts. Their income level, tax regime, deduction pattern and year-wise allocation can all change the result.
Before filing Form 10E, verify the arrear amount shown in the salary slip and Form 16. Check whether the arrear is included in gross salary and whether TDS has been deducted. Collect the breakup by financial year. Compare the calculator result with your employer’s computation if one is provided. Keep copies of payslips, revision letters, old and new salary structures, pension orders or DA circulars. Make sure the relief amount claimed in the income tax return matches the Form 10E filing.
If you have changed jobs, combine income from all employers for the relevant year. A former employer’s arrear can affect your current year tax even if your current employer is not aware of it. If you received arrears after retirement, include pension and other taxable income correctly. If surcharge applies because of high income, or if capital gains and special rate income are involved, the final tax computation can be more complex than a simple salary calculator. In such cases, use the calculator as a starting estimate and confirm with a tax professional.
This content is written to cover practical search intent around salary arrears in India rather than only repeating the formula. Users searching for this topic often ask whether arrear salary is taxable, how to claim Section 89 relief, whether Form 10E is compulsory, how TDS works, what documents are required, and how to calculate arrears after pay revision. The calculator, examples, FAQ schema and semantic headings are designed to answer those questions in a natural way.
