Your TallyPrime license is "lifetime," but without active TSS, you're running outdated software that can't keep up with GST changes, e-invoice updates, or security threats. Here's what every Mumbai business owner needs to know about the hidden risks of expired TSS.
What is Tally TSS (Tally Software Services)?
When you buy TallyPrime, you get a lifetime license for the software. But that license doesn't include ongoing updates. For those, you need Tally Software Services (TSS).
TSS is an annual subscription that gives you:
- Software updates: New features and improvements
- Security patches: Protection against vulnerabilities
- Statutory updates: GST rate changes, TDS rules, e-invoice formats
- Priority support: Direct help from Tally's technical team
Think of it like car insurance. Your car works without it, but you're exposed to risk. With TallyPrime, that risk is compliance failure.
What Happens When TSS Expires?
The moment your TSS expires, your TallyPrime freezes in time. Here's the timeline:
TSS Expiry Timeline
The Real Risks of Running Without TSS
1. GST Compliance Failures
The GST portal and rules change frequently. In 2025 alone, there were:
- 3 major e-invoice format updates
- New ITC matching rules under Rule 36(4)
- Updated e-way bill requirements
- Changes to GSTR-1 and GSTR-3B formats
Without TSS, your TallyPrime doesn't know about these changes. You could file returns with outdated formats or miss new mandatory fields.
2. E-Invoice Rejection
The government periodically updates e-invoice schemas. If your TallyPrime is outdated, the IRP (Invoice Registration Portal) may reject your invoices outright. For a Mumbai trader doing 100+ invoices daily, this means business stops.
3. Security Vulnerabilities
Software vulnerabilities are discovered regularly. Without TSS, you don't receive security patches. Your customer data, financial records, and business secrets remain exposed to known threats.
Real Case: Kalbadevi Trader
A textile business in Kalbadevi ignored TSS renewal for 18 months. When e-invoice became mandatory for their turnover bracket, their TallyPrime couldn't generate compliant invoices. They lost 3 days of billing while scrambling to renew and update. Lost business: estimated ₹4-5 lakhs.
4. No Technical Support
With active TSS, you can call Tally's support team for help with errors, data issues, or configuration problems. Without TSS? You're on your own. Forums and YouTube tutorials can only help so much when your business is stuck.
TSS Renewal Pricing (2026)
TSS pricing is straightforward and transparent:
| TallyPrime Edition | TSS Annual Fee | Per Month |
|---|---|---|
| TallyPrime Silver | ₹4,500 + GST | ₹375/month |
| TallyPrime Gold | ₹13,500 + GST | ₹1,125/month |
Compare this to the cost of:
- One GST notice penalty: ₹10,000 - ₹50,000
- Data recovery after security breach: ₹50,000+
- Lost business from e-invoice rejection: Depends on your daily turnover
TSS is not an expense. It's insurance against much larger costs.
How to Check Your TSS Status
Follow these steps to check if your TSS is active:
- Open TallyPrime
- Press F1 (Help menu)
