Investment Declaration and Proof Submission: A Payroll Guide

Investment declaration and proof submission is the twice-yearly exercise that decides how much TDS an employer deducts from salary. In April, employees declare their tax regime and the deductions they plan to claim; payroll computes monthly TDS on that basis. Towards the end of the tax year, employees submit proofs; payroll verifies them and adjusts TDS for the remaining months. Done well, the process gives employees an accurate, steady TDS. Done badly, it produces a large deduction in February and March and a stream of queries. This guide covers both stages, the documents to collect, verification rules, and a worked recalculation.

Why the Declaration Matters

An employer must deduct tax on estimated salary income for the year. It can only allow exemptions and deductions that the employee claims and, eventually, proves. The declaration (formerly made in Form 12BB; the Income-tax Act, 2025 and its rules use new form references) is the employee's formal statement of:

• The tax regime they want TDS computed under.
• Rent paid and landlord details, for HRA.
• Leave travel claims, for LTA.
• Interest on a home loan and lender details.
• Deductions such as life insurance, PPF, ELSS, tuition fees, health insurance, NPS and education loan interest.
• Other income or house property loss they want the employer to consider.

If an employee does not declare a regime, the employer applies the new regime, which is the default. Under the new regime, most of the items above are irrelevant, because HRA, LTA and most deductions are not available. The main exception is the employer's contribution to NPS.

The Annual Timeline

When	Activity	Owner
April	Collect regime choice and planned investments; publish guidelines	Payroll, employees
April to December	TDS on declared figures; allow declaration updates in a set window	Payroll
Early January	Announce proof submission window and checklist	Payroll
January to mid-February	Employees submit proofs	Employees
February	Verify proofs, communicate rejections, recompute TDS	Payroll
February and March payroll	Recover any shortfall	Payroll
By 15 June	Salary TDS certificate reflects verified figures	Payroll

New joiners declare at joining, along with income and TDS from any previous employer in the same year.

What Proof to Collect for Each Item

Item (old regime)	Acceptable proof	Key checks
HRA	Rent receipts or rent agreement; landlord PAN if annual rent exceeds ₹1 lakh	Period, amount, address; rent to spouse is usually not accepted
LTA	Tickets, boarding passes, invoices	Travel within India; only travel cost; journeys within the block limit
Home loan interest (self-occupied)	Lender's interest certificate	Within ₹2 lakh; lender name and PAN; possession status
Life insurance premium	Premium receipt	Policy holder and insured (self, spouse, children)
PPF, ELSS, tax-saver FD, NSC	Passbook or statement, account statement, deposit receipt	Paid in the current tax year
Children's tuition fees	School fee receipts	Tuition component only, up to two children
Principal repayment of home loan	Lender's certificate	Within the overall investment limit
Health insurance (self, family, parents)	Premium receipt	Paid by a non-cash mode; separate limits for parents
Additional NPS by employee	NPS transaction statement	Within ₹50,000
Education loan interest	Lender's certificate	Loan for higher education of self, spouse or children

Limits quoted are the ones carried over from the 1961 Act: ₹1.5 lakh overall for the investment basket (life insurance, PPF, ELSS, principal repayment, tuition fees, employee PF), ₹25,000 for health insurance for self and family (₹50,000 if a senior citizen), a further ₹25,000 for parents (₹50,000 if senior), and ₹2 lakh for home loan interest on a self-occupied house. Verify current limits and section references under the Income-tax Act, 2025.

Verification Rules Payroll Should Apply

• Date of payment: the investment or payment must fall in the current tax year (1 April to 31 March). A premium paid in March of the previous year does not count.
• Name: the payer and, where relevant, the beneficiary must qualify (for example, life insurance on self, spouse or children).
• Future payments: for payments due between proof submission and 31 March, accept a declaration and ask for proof by a final date, or disallow until proven, as per policy.
• Mode of payment: health insurance premiums paid in cash are not deductible (preventive health check-up is an exception within a small limit).
• Consistency: rent claimed and a home loan in the same city need an explanation.
• Documentation: keep copies; the employer may need to justify allowed deductions.

LTA: The Block Rule

Leave travel allowance is exempt for two journeys in a block of four calendar years. The current block is 2026 to 2029 (the previous one ran from 2022 to 2025). Only the cost of travel by the shortest route is exempt (economy airfare, rail fare in the class used, or equivalent), not hotels or food. One unused journey from a block can be carried to the first calendar year of the next block. Foreign travel does not qualify. LTA is available only under the old regime.

Worked Example: Recalculating TDS After Proofs

Ritu is on the old regime. Her gross salary is ₹10,80,000 (₹90,000 a month). In April she declared:

• Investment deductions: ₹1,50,000.
• Health insurance: ₹25,000.
• Professional tax: ₹2,400.

Tax on declared figures

Taxable income: ₹10,80,000 minus ₹50,000 (standard deduction) minus ₹2,400 minus ₹1,50,000 minus ₹25,000 = ₹8,52,600. Tax: ₹12,500 (2.5 to 5 lakh at 5%) + 20% of ₹3,52,600 (₹70,520) = ₹83,020. Cess at 4%: ₹3,320.80. Total: ₹86,340.80, rounded to ₹86,341. Monthly TDS: ₹7,195 (₹86,341 ÷ 12 = ₹7,195.08).

Proofs in February

Ritu proves only ₹90,000 of investments and the full ₹25,000 of health insurance. Taxable income rises by ₹60,000 to ₹9,12,600. Additional tax: 20% of ₹60,000 = ₹12,000, plus cess of ₹480 = ₹12,480.

Recovery

TDS deducted April to January: 10 × ₹7,195 = ₹71,950. Revised annual tax: ₹86,341 + ₹12,480 = ₹98,821. Balance: ₹98,821 minus ₹71,950 = ₹26,871, recovered in February and March at ₹13,435.50 a month (₹13,436 and ₹13,435). Ritu's take-home falls by about ₹6,240 a month in those two months compared with January. She can still claim any genuine deduction she missed in her return, with proof.

Communicating With Employees

• Publish a one-page guide in April: regime choice, what counts, limits, what proof will be needed.
• Send reminders in December and January with the proof window and a checklist.
• Tell each employee which proofs were accepted, rejected or partially accepted, and why.
• Show the revised TDS for February and March before payroll runs.
• Explain that deductions not submitted can still be claimed in the return.

New Regime Employees

For employees on the default regime, the process is short: confirm the regime, collect PAN, collect previous employer income for mid-year joiners, and confirm any employer NPS arrangement. No rent receipts or investment proofs are needed. Many employers now run two flows: a minimal one for new regime employees and the full declaration and proof flow for old regime employees. This reduces work on both sides and avoids collecting documents that have no effect on TDS.

Special Situations

Mid-year joiners

A joiner in October declares regime, investments and, importantly, salary and TDS from the previous employer for April to September. Without it, your TDS covers only your salary and the employee ends up with a shortfall at filing. Ask for the previous employer's payslips or a statement, and record the figures in the declaration.

Employees who want to change regime mid-year

Set a clear rule, for example one change allowed before the proof window opens. When an employee moves from the old to the new regime, drop all old-regime exemptions from the projection and recompute; the effect is often a lower TDS for the rest of the year. When moving the other way, require declarations and, later, proofs. Whatever happens in payroll, the employee makes the final choice at return filing.

Proofs for payments after the window

Premiums or fees due in March can be accepted on the basis of a declaration and a demand notice, with actual receipts collected by a final date. If not received, reverse the deduction in the March payroll. State this in the policy so it does not feel arbitrary.

Employees with multiple claims on one house

Two employees (for example, spouses) sharing a rented house can each claim HRA only for the rent each actually pays. Ask for the split in the rent agreement or payment records.

Common Mistakes

• Allowing old-regime deductions for employees who did not opt out of the default regime.
• Accepting proofs for payments made in the previous tax year.
• Collecting proofs late in March, leaving no months to spread the recovery.
• Rejecting proofs without telling the employee why.
• Not asking mid-year joiners for previous salary and TDS.
• Failing to keep copies of verified proofs.
• Exempting LTA for foreign travel or hotel costs.

Frequently Asked Questions

What is an investment declaration in payroll?

A statement by the employee, usually in April, of the tax regime and the exemptions and deductions they plan to claim, so the employer can compute monthly TDS.

Do I need to submit proofs under the new tax regime?

Generally no. Most deductions are not available under the new regime, so only PAN, previous employment details and any employer NPS arrangement matter.

What happens if I miss the proof deadline?

The employer disallows the unproven deductions and recovers the extra tax from remaining salary. You can still claim genuine deductions in your return with proof.

Is landlord PAN mandatory for HRA?

Where annual rent exceeds ₹1 lakh, the landlord's PAN or a declaration from the landlord should be provided.

Is this tax advice?

No. This is general information. Limits and forms under the Income-tax Act, 2025 should be verified for the current tax year.
