How to Fill the Tax Calculator: Input-by-Input Guide
A practical guide to entering salary, HRA, house property, capital gains, other income, deductions and TDS in the Venveel tax calculator.
30-Second Summary
The calculator has two input paths:
| Input method | Best for |
|---|---|
| Upload Form 16 | Quick salary, deduction and TDS autofill attempt |
| Manual entry | Exact review using Form 16, AIS, 26AS and your own records |
The calculator works best when you confirm numbers from the right source:
| Calculator section | Best source |
|---|---|
| Salary | Form 16 Part B |
| HRA | Form 16, rent receipts, basic salary |
| House property | Home loan certificate |
| Other income | AIS and bank certificates |
| Capital gains | Broker tax report |
| Deductions | Form 16 and proof documents |
| TDS/TCS | Form 16, Form 16A, AIS, Form 26AS |
Venveel Recommendation
Use the Form 16 upload only as a starting point. Always review detected values before applying them, and do not enter PAN, Aadhaar, passwords, or private document identifiers.

Upload Form 16 or Enter Manually?
The upload option is useful when you want the calculator to quickly detect common Form 16 values such as salary, professional tax, deductions and TDS.
Form 16 can be uploaded as:
| Upload file | What the calculator can usually use |
|---|---|
| Part A | TDS / employer tax deducted details |
| Part B | Salary, allowances, deductions and taxable income details |
| Combined Form 16 | Salary, deductions and TDS together |
If you upload only Part A first, the calculator may detect TDS and ask you to upload Part B for salary and deductions. You can then upload Part B as a second file, review the combined detected values, and apply them together.
If you upload only Part B first, the calculator may detect salary and deduction values, then ask you to upload Part A or enter TDS manually.
Manual entry is still important because:
- Form 16 formats differ by employer.
- AIS income may not be present in Form 16.
- Broker capital gains need separate reports.
- Rent paid and HRA details may need your own records.
- You should always confirm values before filing.
If the upload does not detect a value confidently, leave that row unchecked and enter the number manually in the calculator field.
Where to Download the Documents
| Document | How most users get it |

| Bank interest certificate | Net banking or bank app under tax/interest certificate |
| Form 16A | Deductor, bank, bond platform or company that deducted TDS |

Example Input Sets
Use these sample patterns to understand how the calculator should be filled.
Example 1: New-regime salaried employee
| Field | Example input |
|---|---|
| Gross salary | ₹10,00,000 |
| Basic salary | ₹0 or actual basic |
| HRA received | ₹0 |
| Annual rent paid | ₹0 |
| Savings interest | ₹8,000 |
| 80C | ₹0 |
| 80D | ₹0 |
| TDS/TCS | As per Form 16 |
This user is using the calculator mainly to check new-regime tax and TDS/refund.
After checking the estimate, use the new-regime filing guide to review portal screens before submission.
Example 2: Old-regime comparison with rent
| Field | Example input |
|---|---|
| Gross salary | ₹18,00,000 |
| Basic salary | ₹8,00,000 |
| HRA received | ₹4,00,000 |
| Annual rent paid | ₹5,40,000 |
| 80C | ₹1,50,000 |
| 80D self/family | ₹25,000 |
| NPS 80CCD(1B) | ₹50,000 |
This user should compare both regimes because HRA and deductions can make old regime competitive.
For the decision framework, read the new vs old regime guide.

|---|---|
| Gross salary | ₹22,00,000 |

| STCG on equity | Broker report value |
| LTCG on equity/MF | Broker report value before exemption |

This user should be careful with ITR form selection and schedules.
Profile Section
Resident individual
Select this if you are a resident individual for Indian tax purposes. Rebate rules can depend on residential status.
HRA city is metro
Choose metro only if the rented house is in a metro city for HRA calculation. Otherwise choose non-metro.
Salary Section
Gross salary
Use Form 16 Part B. This is usually salary as per section 17 before deductions.
| Where to look | What to copy |
|---|---|
| Form 16 Part B | Gross salary / salary as per section 17 |
| Salary slip | Use only if Form 16 is not ready |
Basic salary for HRA
Use the basic salary figure from your salary breakup. HRA exemption depends on basic salary.
HRA received
Use the HRA amount from Form 16 or salary breakup.
Annual rent paid
Use actual rent paid during the financial year. Do not enter annual agreement rent if you did not pay for all months.
| If rent changed mid-year | What to enter |
|---|---|
| Same rent all year | Monthly rent x months paid |
| Rent paid for 8 months only | Only 8 months of rent |
| Rent increased during year | Sum actual paid month by month |
| Employer used lower rent in Form 16 | Recheck with rent receipts before overriding |
HRA Check
HRA exemption is not equal to rent paid. It is the minimum of HRA received, 40% or 50% of salary, and rent paid minus 10% of salary.
Other section 10 exemptions
Use this for eligible exemptions such as approved LTA or flexi benefit shown in Form 16.
Professional tax
Use the professional tax amount from Form 16.
Employer NPS contribution
Enter employer NPS contribution if applicable. This can be relevant in the new regime.
House Property Section
Self-occupied home loan interest
Use your lender's interest certificate. The calculator applies the usual cap for self-occupied property loss.
Rental income received
Enter actual rent received from let-out property.
Municipal taxes paid
Enter only taxes actually paid by you during the year.
Let-out property interest
Use the interest certificate for let-out property.
Capital Gains Section
STCG on equity u/s 111A
Use your broker tax report for short-term listed equity or equity mutual fund gains.
LTCG on equity/MF u/s 112A
Use your broker report. The calculator applies the basic exemption for this input.
Other taxable capital gains
Use this for other capital gains that do not fit the first two fields. If your case has debt funds, US stocks, property or foreign assets, review carefully before filing.
Capital Gains Need Extra Care
The calculator gives a planning estimate. For actual filing, match capital gains with the correct ITR schedule, broker report, cost of acquisition and holding period.
Other Income Section
Savings interest
Use AIS and bank interest certificate. This may get 80TTA deduction in the old regime.
FD / deposit interest
Use bank certificate, AIS or Form 16A.
Dividends
Use AIS and broker reports. Include Indian and foreign dividends where applicable.
Other income
Use this for refund interest, bond interest, family pension or any other taxable income.
Old Regime Deductions
80C investments
Common examples include PF, ELSS, LIC, PPF, tax-saving FD and home-loan principal. The calculator caps the allowed amount.
80CCD(1B) self NPS
Enter your own NPS Tier I contribution eligible for additional deduction.
80D self/family and parents
Use health insurance tax certificates. Do not guess. Parent medical expenditure rules can be specific, especially where insurance exists.

|---|---|
| Health insurance tax certificate | 80D premium |
| Preventive health checkup receipt | Within applicable limits |
| Parent medical bills | Check eligibility carefully before claiming |
80G deductible amount
Enter the deductible amount, not always the donation amount. Some donations qualify for only 50%.
| Donation receipt says | What to enter |
|---|---|
| 100% eligible | Full eligible amount |
| 50% eligible | Half of donation amount |
| Missing PAN/registration details | Verify before claiming |
TDS & Relief Section
TDS / TCS
Use salary TDS from Form 16, other TDS from Form 16A, TCS from AIS/Form 26AS and any other available tax credit.
Advance / self-assessment tax
Enter tax already paid through challans.
Foreign tax relief
Use this only if you are eligible and have the required details. Foreign dividends and foreign assets can require extra schedules.
What to Do After Calculator Shows the Result
- Compare old and new regime.
- Check why the recommended regime wins.
- Reconcile the numbers with Form 16 and AIS.
- Keep proofs for deductions.
- File on the income-tax portal or share the calculation with your CA.
If the calculator recommends new regime, continue with the new-regime filing guide. If old regime looks better, recheck the logic in the new vs old regime guide before filing.
Final Filing Reminder
The calculator is a planning and review tool. Final filing should follow the Income Tax portal, latest forms, and your complete document set.
Future Feature: Private Form 16 Import
We plan to add a privacy-first Form 16 import where the PDF is read in your browser and not uploaded or stored. Users will still review every extracted number before using it.
Frequently Asked Questions
Do I need to enter every field in the calculator?
No. Enter only the fields that apply to you. For example, if you do not have rental income or capital gains, leave those fields as zero.
Should I enter gross 80C or only the allowed limit?
Enter your gross eligible 80C amount. The calculator applies the usual cap internally.
Where do I find TDS and TCS?
Use Form 16 for salary TDS, Form 16A for non-salary TDS, and AIS/Form 26AS for TDS, TCS and tax paid cross-checks.
Can I use this calculator instead of a CA?
Use it as a planning and review tool. If you have business income, complex capital gains, foreign assets, crypto, multiple properties or notices, professional review is safer.
