Choosing Your DSC Validity Period
One, two or three years. The right answer depends on how often you file, not on which looks cheapest today.
What a shorter certificate actually costs you
A one-year certificate looks cheaper. What it also buys is another renewal next year — another video KYC, another round of registering it on every portal you use, and another date to remember.
For someone who signs once a year, that is fine. For a contractor who bids regularly or a business filing GST monthly, it means an annual interruption and an annual chance of it lapsing at the wrong moment.
The cost of an expiry discovered on a filing deadline is much larger than the difference between validity periods.
A rough guide
| If you | Consider |
|---|---|
| File monthly or bid regularly | Three years. Fewest interruptions, lowest cost per year |
| File occasionally, a few times a year | Two years. A reasonable middle |
| Need it for one specific filing | One year, though check whether the same need recurs |
| Are unsure how long the role lasts | Shorter. A certificate belongs to a person, so a role ending means it is not transferable anyway |
One thing that argues the other way: a longer certificate means a longer window in which a lost token is a problem. If the token is not kept securely, that is worth weighing — see our page on using your DSC safely.
