How to Fill DAF-1 for UPSC Mains 2026: Step-by-Step Application Guide

Candidates who qualify the UPSC Civil Services Preliminary Examination must complete the Detailed Application Form-I (DAF-1) to become eligible for the Civil Services Main Examination. Through DAF-1, candidates confirm their application details, declare cadre preferences, provide disability-related information (where applicable), and complete other mandatory formalities required by the Union Public Service Commission (UPSC). 

Since the form is accepted only for a limited period, candidates should verify every detail carefully and complete the submission process before the deadline.

UPSC Mains DAF-1 2026 Application Process 

After the release of UPSC Prelims results, the essential next step for eligible candidates is to complete the Detailed Application Form – 1 (DAF-1) for the UPSC Civil Services Mains Examination. 

This form is mandatory for all aspirants wishing to appear for the Mains examination. Understanding the process and accurately filling DAF-1 is crucial for proceeding to the next stage of the UPSC selection process.

UPSC DAF-1 2026 Submission Timeline 

The Mains form filling process occurs in two distinct stages: once before the Mains examination, which is the current phase, and again after clearing Mains, specifically for the interview stage. The present DAF-1 requires candidates to provide minimal details and involves a small fee for certain categories. 

The crucial deadline for submitting this form is June 28th. While the process typically takes about 30 minutes to one hour, involving minor updates, it is highly advisable to complete the form well before the deadline to avoid any last-minute technical difficulties.

Read-Only and Editable Sections in DAF-1 

Upon accessing the DAF-1, candidates will find that several sections are in read-only mode, meaning they cannot be edited at this stage. These include:

• Common Application Form details (such as name and Aadhaar number).
• Education Details (e.g., 10th CGPA).
• Prelim Exam Details.
• The chosen Mains Examination Centre.

Candidates must simply click ‘Next’ to proceed through these uneditable sections. While direct updates are not possible now, the Commission might permit corrections or updates to some of these details at a later stage, possibly during the interview, but not at the current DAF-1 submission phase. Similarly, details regarding OBC and EWS status, as well as previously answered questions, are also read-only.

However, specific sections allow for major updates and declarations:

• Disability-Related Details: Candidates with benchmark disabilities can update information regarding scribe details, request big font, or seek compensatory time as needed.
• Cadre Preference: Candidates are required to declare their Home Cadre state for both IAS and IPS services. Following this, they will be asked if they wish to make their declared home state their first preference.
  • If ‘Yes’: The home state will be automatically designated as the first preference.
  • If ‘No’: The home state cannot be chosen for cadre allocation.
    This preference setting is applicable to both IAS and IPS services and should be made after understanding the relevant Cadre Allocation Policy.

Understanding UPSC Cadre Preferences 

The Cadre Allocation Policy has undergone updates, resulting in cadres being divided alphabetically into approximately 25 distinct groups. Candidates should carefully consider this policy when filling out their preferences. 

It is important to note that these cadre preferences can be updated again after the Mains examination, specifically before the interview stage, offering a valuable second opportunity to review and adjust choices.

DAF-1 Fee Payment and Final Submission 

A critical final step in the DAF-1 submission process is the fee payment. For applicable candidates, such as Unreserved male candidates, a specific fee (e.g., ₹200) must be paid. It is essential to understand that candidature is considered final only after successful fee payment. Upon successful completion of the payment and submission, candidates should receive a confirmation email, which indicates that the form has been properly submitted.

• For Non-PwBD Candidates: The primary actions involve updating cadre and home state preferences and paying the applicable fee. All other sections primarily require clicking ‘Next’.
