TSS (Tally Software Services) is the yearly subscription that keeps TallyPrime updated and connected. Renew it before it expires and Tally adds one extra month free. If you let it lapse, TallyPrime keeps running and your data stays safe, but updates and online services stop. Those include GST uploads, e-invoices, e-way bills and connected banking.
This guide covers what TSS includes, what stops when it lapses, what renewal costs, and the best time to renew.
What is TSS in Tally?
TSS is the annual subscription that comes with every TallyPrime licence. A new lifetime licence includes 12 months of TSS. After that you renew it for one or two years at a time. Rental licences include TSS for as long as the rental runs, so rental users don’t renew it separately.
The licence lets you use TallyPrime. TSS keeps it current with tax rules and gives you Tally’s online services.
What you get with active TSS
According to Tally’s renewal page, an active TSS gives you:
- Free upgrades to every new TallyPrime release, installed from inside the product
- Statutory updates when GST or other rules change
- Connected GST services: upload returns and generate e-invoices and e-way bills from TallyPrime
- Connected banking and WhatsApp Business sharing of invoices and reports
- Access from anywhere to business reports and to TallyPrime
- Data sync between branches and consolidation across locations
- TallyDrive cloud backup (up to 1 GB for a single-user licence, 3 GB for multi-user)
What happens if TSS expires?
TallyPrime does not stop working. You can open your companies, enter vouchers and print reports as before. What stops is everything that depends on Tally’s servers or on new releases.
| TSS active | TSS expired | |
|---|---|---|
| Open data, enter vouchers, print reports | Yes | Yes |
| New TallyPrime releases | Yes, free | No |
| GST and statutory updates | Yes | No |
| E-invoices and e-way bills from TallyPrime | Yes | No |
| Uploading GST returns from TallyPrime | Yes | No |
| Connected banking | Yes | No |
| Remote access and branch data sync | Yes | No |
| Cloud backup to TallyDrive | Yes | No |
The risk shows up when a rule changes. For example, a new GST return field or e-invoice format arrives through a release. Without TSS your Tally keeps working on the old rules, and your staff start fixing things by hand on the government portal.
Is TSS renewal compulsory?
No. TSS is optional, and some businesses can manage without it. A small firm with no e-invoicing obligation, no branches and no remote users may decide to let it lapse.
Renew if any of these apply:
- Your turnover requires e-invoicing (₹5 crore and above under current GST rules)
- You generate e-way bills or upload GST returns from Tally
- You use connected banking or WhatsApp sharing
- Anyone works on Tally from home or a branch
- You want new releases as GST rules change
For most GST-registered businesses that means renewing.
How much does TSS renewal cost?
Tally’s published renewal prices, excluding 18% GST:
| Licence | 1 year | 2 years |
|---|---|---|
| Silver (single user) | ₹4,500 | ₹8,100 |
| Gold (multi-user) | ₹13,500 | ₹24,300 |
| Auditor edition | ₹6,750 | ₹12,150 |
Source: Tally Solutions renewal page, checked November 2026. Confirm the price before you pay.
The two-year plan costs 10% less than renewing twice. For a Gold licence that saves ₹2,700 before GST.
When should you renew? The new rules since December 2025
Tally changed how TSS validity works from 1 December 2025 (Tally announcement):
- Renew before expiry and you get one extra month free. Your new period starts from your current expiry date, not from the day you pay, so renewing early loses no days.
- Renew after expiry and there is no bonus month. The new year runs from the day you renew.
- Validity is a straight 365 days for a one-year renewal and 730 days for two years. Earlier rules tied it to the financial year.
Example from Tally: if your TSS expires on 30 June 2025 and you renew before that date, it now runs to 31 July 2026. Renew on 5 July 2025 instead, after expiry, and it runs only to 4 July 2026.
Two practical rules follow:
- Renew a few weeks before expiry. You keep the free month and never lose online services.
- Never let it lapse near month-end or year-end. A lapsed TSS during the March close, or near a GST due date, stops e-invoices and return uploads exactly when you need them.
The bonus month does not apply to every licence type. Tally excludes GVLA-tagged and NGO licences.
How to renew TSS in TallyPrime
- Open TallyPrime and press Alt+R (Manage TSS Renewal). Or go to F1 (Help) > Settings > License > Manage License and press F9 (Renew TSS).
- On Tally’s renewal page, choose one or two years and check the licence details.
- Pay online. Tally emails a confirmation.
- In TallyPrime, go back to Manage License and update the licence so the new validity shows.
- Install the latest release from inside TallyPrime if one is waiting.
If you prefer not to pay online, or want the upgrade and licence update done for you, your Tally partner can renew it.
Still on Tally.ERP 9?
Tally has announced that TSS renewal is being discontinued for Tally.ERP 9 licences, and its upgrade pages give the date as 16 August 2026. Tally.ERP 9 keeps working, but it gets no further updates.
Your route to TallyPrime depends on your TSS history. Tally lists a free upgrade for licences whose TSS was active on or after 9 November 2020, and a paid upgrade for others. Your existing licence and data move across. Ask your Tally partner to check your serial number and the current position before you plan the move.
Frequently asked questions
Do I lose the remaining days if I renew early?
No. Since December 2025 the new period starts from your current expiry date, and you get an extra month on top.
Does a rental licence need a separate TSS renewal?
No. TSS is included for the rental period and renews with the rental.
Will my data be deleted if TSS expires?
No. Your company data stays on your computer and opens normally. Only updates and online services stop.
Can I renew TSS for two years?
Yes. A two-year renewal costs 10% less than two one-year renewals.
