-   **Standard Deduction:** ₹50,000 is applied under the old regime and ₹75,000 under the new regime in this example
-   **Rebate:** Since taxable income under the new regime is ₹9,25,000, the eligible resident individual gets Section 87A rebate and pays zero tax
-   **Tax Difference:** Old regime tax payable is ₹70,200, while new regime tax payable is ₹0 in this example

Old regime rebate note: Under the old regime, Section 87A rebate applies to eligible resident individuals with taxable income up to ₹5 lakh. The maximum rebate is ₹12,500.

### New Regime Slabs

30%

New regime rebate note: Under the new regime, Section 87A rebate is available up to ₹60,000 for eligible resident individuals with taxable income up to ₹12 lakh.

The old regime may work better if you claim deductions and exemptions such as [**80C, 80D, HRA**](https://busy.in/tds/part-b-of-salary-allowances-exemptions-sec-10-deductions-80c-80d-80e/), or home loan interest. The new regime may work better if you have fewer deductions and want a simpler tax calculation with revised slab rates. Since the new regime is the default option, compare both regimes before filing and choose the one that gives lower tax payable.

## Common Deductions Used in Income Tax Calculation

Deductions reduce your taxable income and can affect your final tax payable. Limited deductions such as standard deduction and employer’s NPS contribution may still be available under the new regime, subject to eligibility. Some common deductions include:

80C

### Section 80C

Includes eligible investments such as PPF, ELSS, EPF, life insurance and home loan principal repayment.

80D

### Section 80D

Applies to eligible health insurance premiums paid for self, family and parents.

24(b)

### Section 24(b)

Applies to home loan interest, subject to applicable limits and property type.

80CCD

### Section 80CCD

Applies to eligible National Pension System contributions.

HRA

### HRA Exemption

Available to eligible salaried taxpayers under the old regime if they [**receive HRA and pay rent**](https://busy.in/tds/calculate-hra-step-by-step/).

Note: Most deductions and exemptions are available mainly under the old regime. The new regime allows limited deductions, so always check eligibility before filing.

## Frequently asked questions

### What is the BUSY ITC Calculator?

BUSY's ITC Calculator is a free online tool that shows how available Input Tax Credit can be adjusted against GST liabilities under IGST, CGST and SGST. It helps accounts teams and GST filers estimate the exact cash amount payable before filing GSTR-3B.

### How does the ITC Calculator work?

You enter GST payable and available ITC for each tax head. The calculator applies IGST credit first and then adjusts CGST and SGST credits as per the permitted set-off logic. The output shows net cash payable and any unused ITC balance.

### Why is the order of ITC utilisation important?

The order matters because GST credit cannot be used freely across all tax heads. IGST credit must be exhausted first. CGST credit cannot be used for SGST liability, and SGST credit cannot be used for CGST liability. Following the correct order helps avoid excess cash outflow, short payment, and errors while finalising GSTR-3B.

### Who should use this calculator?

GST-registered businesses, accounts teams, tax consultants and Chartered Accountants can use this calculator before preparing or reviewing GSTR-3B. It is useful when credit is available under multiple tax heads and the final cash payment needs to be checked.

### Can this calculator help reduce GST cash payment?

Yes. It helps you use eligible ITC before depositing GST in cash. This can reduce unnecessary cash outflow, especially when there is a high IGST credit balance that can be adjusted against more than one liability head.

### Does the calculator show unused ITC?

Yes. The Tax Credit Summary shows credit used and remaining ITC balance. This is useful when credit under one head exceeds the current period liability and the unused eligible balance needs to be carried forward.

### Is this calculator useful before filing GSTR-3B?

Yes. You can use it before finalising GSTR-3B to check your net cash liability after ITC adjustment. This helps avoid both excess cash deposit and short payment.

### Do I need to account for RCM liability separately?

Yes. GST payable under Reverse Charge Mechanism must be paid in cash and cannot be adjusted using ITC at the time of payment. Once paid, eligible RCM tax may become ITC subject to GST conditions.

### Are blocked credits under Section 17(5) included?

No. The calculator does not identify blocked credits under Section 17(5). Remove ineligible ITC before entering the available credit amount, such as blocked motor vehicle credit, food and beverage credit, club membership credit, and restricted works contract credit.

### Do I need a login or account to use this calculator?

No. BUSY's ITC Calculator is free to use on the web without registration or login.

### How does this connect with BUSY Accounting Software?

BUSY helps with purchase records, GST reports, GSTR reconciliation and GST payment workflows. The ITC Calculator acts as a quick pre-filing check before you finalise GST payment in your accounting system.
