Your investment declaration tells your employer about your tax-saving investments and exemptions for the financial year, so your monthly TDS (Tax Deducted at Source) can be computed under Section 192. Declaring early means less tax is held each month instead of waiting for a refund at year-end. This guide covers how to use the declaration page in the portal. For the deductions themselves - which sections exist, what qualifies, and the statutory limits - see Investment Declarations in the Tax & Compliance section.

Opening the Declaration

Click Investment Declaration

Under Acknowledgements, click Investment Declaration.
It lives at app.omnivoo.com/employee/investment-declaration, and the Declare your investments task on Home links straight to it. The page header reads Investment Declaration with the year beneath it. Inside the form, a banner names the year and explains that the form declares investments and exemptions to your employer for TDS computation.

Tax year 2026-27 onwards

From 1 April 2026 the Income-tax Act 2025 replaces the 1961 Act. It renumbers the sections and forms, and calls the year a tax year instead of a financial year and assessment year. For tax year 2026-27 onwards the form shows the new number with the old one in brackets, for example Section 123 (80C), and the banner reads “Declaration for tax year 2026-27”. The declaration itself is now Form 124 (it was Form 12BB) and the previous employer’s statement is Form 122 (it was Form 12B). For FY 2025-26 and earlier the form keeps the old names, for example “Declaration for FY 2025-26 (AY 2026-27)”. The full list of new section numbers is in Investment Declarations.
The declaration also appears as the Investment Declaration step of the guided onboarding wizard (deep link ?step=investment-declaration). New hires submit it there while setting up their account. See Setting Up Your Account (Onboarding).

Choosing Your Tax Regime

At the top of the form, choose Old Regime or New Regime. New Regime is selected by default.
When New Regime is selected, the sections it does not allow (HRA, 80C, home loan interest, NPS, 80D, education loan, donations and the other Chapter VI-A deductions) are hidden, along with the house property loss and the previous employer’s PF and Professional Tax. Only Other income and Previous employer salary and TDS remain, because those still change your TDS, and the summary lists just those. Your employer’s NPS contribution under 80CCD(2) still counts in the new regime, and payroll applies it for you. Anything you typed under Old Regime is kept and comes back if you switch.

Filling in the Form

The form is organized into collapsible sections (HRA, Section 80C, home loan interest, NPS, Section 80D health insurance, education loan, donations, and more). Enter the annual amount you expect for each item. Some fields become required once you declare an amount. Missing any of these blocks Submit declaration:
  • HRA - if you enter rent, you must also provide the landlord name and address. The Landlord PAN is required when your annual rent exceeds Rs 1,00,000.
  • Home loan interest (Section 24) - if you enter interest above zero, the lender name and lender address are required. The Lender PAN is required only when the loan is not from a bank or financial institution, for example a loan from an individual. Untick Loan is from a recognised financial institution for those.
  • Education loan (Section 80E) - if you enter an interest amount, the lender name is required.
  • Donations (Section 80G) - each donation you add needs a donee name and an amount greater than zero.
  • Each section shows its statutory cap. If you enter more than a cap allows, the form flags it and the amount is clamped (adjusted down) when you submit.
Section 80GG (rent paid when you receive no HRA) only appears in the form when you have not declared any HRA / monthly rent. As soon as you enter monthly rent under HRA, the 80GG field is hidden. A few deductions work differently from a plain amount:
  • EPF - the PF deducted from your salary counts toward 80C automatically. Do not add it to the 80C fields. A PF deduction from a previous employer this year goes under Previous employer.
  • 80EE and 80EEA - you can claim one or the other on a home loan, not both. Once you enter one, the other field is closed.
  • 80TTA and 80TTB - 80TTB is only for employees aged 60 or more, in place of 80TTA. Once you enter one, the other field is closed.
  • 80DD and 80U - these are a flat ₹75,000 whatever you spent, or ₹1,25,000 when you tick severe disability (80% or more).
  • 80DDB - capped at ₹40,000, or ₹1,00,000 when you tick patient is a senior citizen (60+).
  • Previous employer - under the Old Regime you can also enter the Employee PF deducted and Professional Tax deducted by your previous employer this year.
For the full list of sections and what each one covers, see Investment Declarations.

Saving a Draft vs Submitting

On the Investment Declaration page, the form has two actions at the bottom:
  • Save as draft - saves your progress without sending it for TDS computation. You can come back and keep editing. A “Draft saved successfully” message confirms the save.
  • Submit declaration - sends the declaration to your employer for TDS computation. A confirmation dialog (“Submit investment declaration?”) appears showing your total Chapter VI-A deductions. Click Confirm submit to finish, or Cancel to go back. A “Declaration submitted successfully” message confirms it.
During onboarding there are no buttons in the form: Continue submits it, and a note above says so. Once submitted, the amounts are locked, because your employer uses them for TDS. Email contact@omnivoo.com if they need to change. You can still add proofs after you submit.

Statutory Cap Adjustments

If any amount you entered is above its statutory cap, after you save or submit the form shows an amber notice: “We adjusted N fields to comply with statutory caps,” listing each field with the declared amount, the applied amount, and the reason. This is expected - the capped amount is what is used for your TDS.

Uploading Proof Documents

Each section that supports proof (for example rent agreement / rent receipts for HRA, 80C proofs, home-loan certificate, health-insurance receipts, NPS proofs) has its own Add file control.
You must Save as draft at least once before you can attach proofs. Until the declaration is saved, each proof slot shows: “Save the declaration as a draft to attach proofs.” After that you can add proofs at any time, including after you submit, which is when most proofs arrive (January and February).
To upload a proof:
1

Save the declaration as a draft

Save the declaration as a draft (if you have not already).
2

Click Add file

In the relevant section, click Add file and choose your document.
3

Check the status badge

The file appears in that section with a status badge.
Proof rules:
  • Accepted file types: PDF, JPEG, PNG, WebP.
  • Maximum size: 10 MB per file. Larger files are rejected with a message.
  • Status: each proof shows pending, approved, or rejected after it is reviewed.
  • Click a file’s name to open it.
  • You can delete a proof you uploaded - except once it is approved, which is locked (“Approved proofs cannot be deleted”).
  • Donation receipts need one extra step: a donation must be saved before its Donation receipt (80G) slot appears. Until you save, the donation shows “Save the declaration first to attach a receipt for this donation.”
The summary card shows how many proofs you have uploaded against the number of fields where you declared an amount.

Status

The status badge at the top of the form reflects where your declaration stands:
Only declare investments you are confident you will actually make during the financial year. If your actual investments fall short, you may face higher TDS in the final months (January to March) to compensate, or a tax liability when you file your return.

When to Update Your Declaration

  • Start of the financial year (April) - submit an initial declaration based on planned investments.
  • Mid-year - update it if your plans change (for example you take a home loan or change health insurance).
  • Year-end (January to February) - finalize it with actual amounts and upload your proofs before your employer’s deadline.
