Indian tax, GST and EPF forms, explained
What each form actually is, who files it, when, and the mistake that costs people the most. Written for the person filling it in, not for someone who already knows.
Income tax· 13
Form 16
TDS certificate on salary
The certificate your employer issues showing the salary paid to you and the tax deducted from it. Part A comes from TRACES and carries the quarterly TDS summary; Part B is the salary breakup and the deductions your employer allowed.
Form 16A
TDS certificate on income other than salary
The TDS certificate for income that is not salary — bank interest, professional fees, rent, commission. Issued quarterly by whoever deducted the tax.
Form 26AS
Annual tax statement
Your consolidated tax statement: every rupee of TDS credited against your PAN, advance tax and self-assessment tax you paid, and refunds issued.
Annual Information Statement (AIS)
AIS and TIS
A much wider statement than Form 26AS: interest, dividends, securities and mutual fund transactions, foreign remittances and more, gathered from the entities that reported them. The TIS is its summarised sibling.
ITR-1 (Sahaj)
Sahaj
The simplest return form, meant for a resident individual with salary or pension, one house property, and other income such as bank interest, within the prescribed income limit.
ITR-2
The return for individuals and Hindu Undivided Families who do not have income from a business or profession — capital gains, more than one house property, foreign income or foreign assets all land here.
ITR-3
The return for individuals and HUFs carrying on a business or profession, including partners in a firm. It carries full financial statements and, where applicable, an audit report.
ITR-4 (Sugam)
Sugam
The return for those declaring income on a presumptive basis under the relevant sections, rather than maintaining full books.
Form 15G
declaration to avoid TDS on interest
A self-declaration that your total income for the year will be below the taxable limit, so the bank should not deduct tax from your interest.
Form 15H
senior citizen declaration to avoid TDS
The senior citizens' version of Form 15G: a declaration that the tax on your estimated total income will be nil, so no tax should be deducted from your interest.
Form 10E
relief for salary arrears
The form that supports a claim for relief where salary arrears or advance salary have pushed you into a higher bracket in the year you received them.
Form 12BB
employee investment declaration
The statement you give your employer listing the deductions and exemptions you intend to claim — rent, home loan interest, investments, leave travel — so the right amount of TDS is deducted from your salary.
Form 15CA
declaration for a foreign remittance
The declaration filed before money is remitted to a non-resident, stating the nature of the payment and the tax deducted on it.
PAN & identity· 4
Form 49A
PAN application for Indian citizens
The application for a Permanent Account Number by an Indian citizen, and the same form used to request corrections to an existing PAN.
Form 49AA
PAN application for foreign citizens
The PAN application for individuals and entities who are not Indian citizens, including foreign companies and certain investors.
Aadhaar enrolment form
new Aadhaar application
The application for a new Aadhaar number, completed at an enrolment centre where your photograph, fingerprints and iris scan are captured on the spot.
Aadhaar update / correction form
Aadhaar name, address or date of birth change
The request to change details already recorded against your Aadhaar — name, address, date of birth, gender, mobile number or email.
GST· 4
GSTR-1
outward supplies return
The return reporting your outward supplies — invoice-level sales data that flows into your buyers' input tax credit.
GSTR-3B
summary return and tax payment
The summary return where tax is actually paid: outward supplies, input tax credit claimed, and the liability discharged for the period.
GSTR-9
annual GST return
The annual consolidation of the returns you filed during the year, reconciling outward supplies, input tax credit and tax paid.
GST REG-01
GST registration application
The application for GST registration: business details, place of business, bank account, and the authorised signatory, with documents uploaded in support.
EPF· 4
EPF Form 19
PF final settlement
The claim to withdraw the full provident fund balance when the account is being closed — typically after leaving employment and not rejoining.
EPF Form 10C
pension withdrawal benefit
The claim relating to the pension portion of your PF — the withdrawal benefit or the scheme certificate, as opposed to the provident fund balance itself.
EPF Form 31
PF partial withdrawal / advance
The claim for a partial withdrawal from your PF while still employed — for specified purposes such as housing, medical treatment, education or marriage.
EPF Form 13
PF transfer on changing jobs
The request to transfer a provident fund balance from a previous employer's account to the current one, rather than withdrawing it.
Company & MCA· 4
SPICe+ (INC-32)
company incorporation form

DIR-3 KYC
annual director KYC
The annual confirmation of a director's own details against their Director Identification Number, filed by the individual rather than by the company.

The periodic re-confirmation of your identity and address that banks are required to carry out on existing customers, with fresh proof where anything has changed.
FATCA / CRS declaration
tax residency self-certification
A self-certification of where you are tax resident, so financial institutions can report accounts to the right jurisdiction under the international exchange-of-information arrangements.
Bank nomination form
DA-1 / nomination in a bank account
The form recording who receives the balance in an account, deposit or locker if the holder dies, so the bank can release it without a court process.
Questions
- Do you host the actual form PDFs?
- No, deliberately. Government forms are revised without notice, and a stale copy served from our domain would be worse than none — you would file last year’s version and find out months later. Every page links to the issuing authority, whose copy is the current one.
- Can DiemDesk file my return or claim?
- No. These are explainers, and our tools are document tools. Filing happens on the income tax portal, the GST portal or the EPFO member portal. What we help with is everything around it: combining two Form 16s, compressing proofs under a payroll portal’s upload cap, turning a statement into rows, redacting an account number before forwarding.
- Why does an Indian forms library exist on a PDF tools site?
- Because the document work is the part nobody helps with. A filing season is mostly PDFs: certificates to reconcile, scans to shrink, statements to convert. Those jobs are what these tools do, and they do them without your documents leaving your device.
