SBI TTBR rate: what it is, how to find it, and why it determines your RSU tax

Every RSU holder in India will come across the term "SBI TTBR" during tax filing season. It appears in your Form 16, your payslip at vest, and in the ITR-2 instructions. If you have ever looked at your Form 16 Part B and seen a perquisite value that seemed slightly off from what you'd calculate by multiplying shares × USD price × the Google rate — the SBI TTBR is why.

This guide covers what TTBR is, why the Income Tax Act uses it, how to find the rate for any date (past or present), how your employer uses it in the perquisite calculation, and how the same rate flows into dividends, Schedule FA, and Form 44.

What is SBI TTBR?

SBI TTBR stands for State Bank of India Telegraphic Transfer Buying Rate.

Breaking that down:

• State Bank of India — not a rate you calculate or negotiate. The IT Act specifies SBI's rate, not any bank's rate.
• Telegraphic Transfer — the method of international wire transfer. "TT rate" is the rate applied to electronic foreign currency transfers, as opposed to cash rates (used at airport currency counters) or draft rates.
• Buying Rate — the rate at which SBI buys foreign currency from you. When you receive USD and convert to INR, SBI applies the buying rate. When you buy USD to send abroad, SBI applies the selling rate (higher).

In plain terms: SBI TTBR is the rupee equivalent SBI gives you per USD when you transfer USD into your Indian account. It is set by SBI each business day, based on interbank market rates with a small spread built in.

The current SBI TTBR for USD is typically ₹0.30–₹0.80 less than the mid-market rate you would see on Google or XE.com. So if the interbank USD/INR rate is ₹84.00 on a given day, the SBI TTBR might be ₹83.50.

Why the Income Tax Act uses SBI TTBR — not the market rate

Rule 26 of the Income Tax Rules, 1962 prescribes how foreign currency income must be converted to INR for tax purposes. The rule specifies:

"Where any income referred to in section 5(2) is received in foreign currency, it shall be converted to Indian currency at the buying rate of exchange of the State Bank of India on the date of accrual or receipt of such income."

Why SBI specifically? SBI is India's largest public sector bank and the rate has been a statutory benchmark since the original framing of the Income Tax Rules. RBI uses SBI's daily rates as a reference point, and SBI publishes rates every working day before markets open — creating a consistent, auditable daily benchmark. No interpretation or negotiation — the same rate applies to everyone.

Why the buying rate and not the mid-rate? The rationale is that the buying rate represents what you would actually receive in rupees when converting your foreign income. The mid-market rate is theoretical; the buying rate reflects the real-world transaction rate. Using the selling rate would artificially inflate the taxable perquisite.

The practical effect: Your RSU perquisite is slightly lower than what you'd calculate using the Google rate, because the TTBR is below the mid-market rate. On a $20,000 vest with TTBR ₹0.50 below mid-market, the INR perquisite is ₹10,000 lower than the "headline" calculation — reducing your taxable perquisite by ₹10,000 and saving approximately ₹3,400 in tax at the 34.3% effective rate.

How to find the SBI TTBR rate — today and historical

Today's rate

The SBI TTBR is published daily at sbi.co.in → Personal Banking → Forex → Forex Rates. The page shows a table of TT Buying Rate, TT Selling Rate, and Bill Rates for multiple currencies (USD, EUR, GBP, etc.). The USD TT Buying Rate is the number you need.

Rates are typically published before 10:00 AM on business days. On bank holidays, the rate defaults to the previous business day's rate.

Also available via FBIL: Financial Benchmarks India Pvt Ltd (fbil.org.in) publishes reference rates daily. While FBIL's published rate is the RBI reference rate (a mid-market benchmark), many tax practitioners refer to it alongside the SBI TTBR for cross-reference. The Income Tax Act specifies SBI, not FBIL — so use the SBI TTBR for actual tax calculations.

Historical rates (for past vest dates)

For past vest dates — needed when computing perquisites for prior quarters or amending a return — SBI TTBR historical rates are available at:

1. SBI website → Forex Rates → Historical Rates: Enter a date range; the page returns a downloadable table of daily TT rates. Available for several years of history.

2. Your employer's Form 12BA: The Form 12BA (attached to Form 16) should list each RSU vest event with the date, shares vested, USD price, exchange rate used, and INR perquisite. The rate shown is the TTBR your employer applied on each vest date.

3. Your equity platform's tax documents: Fidelity, Morgan Stanley at Work (StockPlan Connect), E*Trade Equity Edge, and Schwab Equity Awards all provide annual tax summaries. Some platforms show the exchange rate used per vest event; others require you to pull it from the SBI website using the vest date.

Important: The rate used is the TTBR on the vest date — the date the shares were released to you, not the date of sale, not the date you received the sell-to-cover proceeds. If your vest date is August 15 and you received the shares on August 16 (due to broker processing), use August 15 (the release date per your plan documents).

How the SBI TTBR enters the RSU perquisite calculation

The perquisite formula under Section 17(2) read with Rule 3(8) and Rule 26:

Perquisite (INR) = FMV at vest (USD) × shares vested × SBI TTBR on vest date

FMV at vest is the fair market value of the shares on the vest date — typically the closing price or the volume-weighted average price (VWAP) for that day on the NYSE/NASDAQ, as specified in your company's equity plan document. Most US equity plans use the closing price on the vest date.

Example:

Vest date	Shares vested	MSFT closing price (USD)	SBI TTBR (₹)	Perquisite (INR)
August 15, 2026	25 shares	$422.50	₹83.80	25 × $422.50 × ₹83.80 = ₹8,85,135

Your employer deducts TDS on this ₹8,85,135 in the August payroll — typically via the sell-to-cover mechanism, where enough shares are sold to cover the TDS liability.

The sell-to-cover amount = Perquisite × effective TDS rate. If TDS rate is 34.3% (30% + 10% surcharge + 4% cess), TDS = ₹8,85,135 × 34.3% = ₹3,03,601. The employer sells enough shares to cover this and remits it to the IT Department.

You receive: The remaining shares (after sell-to-cover) plus a payslip showing the perquisite and TDS deducted. The perquisite value appears in Form 16 Part B → Section B(1)(b), and TDS appears in Form 16 Part A.

TT Buying Rate vs TT Selling Rate vs Cash Rate — what's the difference?

SBI publishes three types of rates that are easy to confuse:

Rate	What it is	When used
TT Buying Rate	Rate at which SBI buys USD from you (incoming wire)	RSU perquisites, dividends received, income from abroad
TT Selling Rate	Rate at which SBI sells USD to you (outgoing wire)	LRS remittances, sending money abroad
Bill Buying Rate	Rate for documentary bills (import/export)	Trade finance; not relevant for RSU holders
Cash Buying Rate	Rate for physical currency notes	Airport counters; always lower than TT rate

For RSU tax calculations, always use the TT Buying Rate. Using the TT Selling Rate would produce a higher INR value — overstating your perquisite. Using the mid-market (Google) rate would also overstate it.

One practical check: The TTBR should always be lower than the rate you see on Google Finance or XE.com for the same day. If you're getting a number higher than the Google rate, you've pulled the wrong column.

How to verify the rate your employer used

Your Form 12BA (part of Form 16, showing perquisite details) should include the exchange rate applied on each vest date. To verify it:

1. Note the vest date for each RSU event.
2. Look up the SBI TTBR for that date (SBI historical rates page).
3. Check that: Form 12BA perquisite ÷ (shares × USD price) ≈ SBI TTBR

A small difference (less than ₹0.50 per dollar) may be due to:

• Employer using a slightly different USD price (some plans use opening price rather than closing price)
• 1-day lag in settlement (some employers use the T+1 date)
• Rounding in the form

A larger difference may indicate a data error worth flagging to your employer's payroll team before you file. You cannot simply override the Form 16 in your ITR-2 filing — any correction needs to come from the employer via a revised TDS return and corrected Form 16.

SBI TTBR for dividends from US stocks

If you hold shares of US companies (MSFT, ORCL, QCOM, AMZN, AAPL) and receive quarterly cash dividends, the dividends must also be converted using SBI TTBR.

Calculation:

Dividend income (INR) = Gross USD dividend received × SBI TTBR on date of receipt

The "date of receipt" is the date the dividend is credited to your brokerage account, not the ex-dividend date or the payment date (though for most brokerages these are close together).

US withholding tax (Form 44): The IRS withholds 25% (assuming your broker has a valid W-8BEN on file) before the dividend reaches your account. For Form 44 (foreign tax credit):

US withholding credit (INR) = USD withholding amount × SBI TTBR on date of withholding

The "date of withholding" is typically the same as the payment date. Your broker's Form 1042-S (issued by March 15 for the prior calendar year) shows the gross dividend, withholding amount, and dates — use these for Form 44 and ITR-2.

SBI TTBR for Schedule FA — peak and closing values

Schedule FA (Foreign Asset disclosure in ITR-2) requires two value fields for each foreign equity holding:

1. Peak value — the highest INR value of your holdings during the calendar year (Jan 1–Dec 31)
2. Closing value — the INR value of your holdings on December 31

Both are calculated using SBI TTBR:

Peak value = (highest share count during year × USD price on that date) × SBI TTBR on that date
Closing value = (shares held on Dec 31) × (Dec 31 USD closing price) × (SBI TTBR on Dec 31)

For the peak value, you need to identify the day when the INR value of your holdings was highest. This is typically either:

• A day when a large vest occurred (shares just vested + high USD price + favourable TTBR), or
• A day near the end of the year when the stock hit its high

Most holders approximate the peak value using the stock's 52-week high during the calendar year. This is acceptable; you don't need to check every single day.

December 31 TTBR is an important one to save each year. Bookmark the SBI forex rates page or download the rate on January 2 (the first business day; Dec 31 rate is used for the non-business-day default).

Common errors with SBI TTBR — and how to avoid them

Error 1: Using the mid-market rate (Google Finance / XE.com)

The Google Finance USD/INR rate is the interbank mid-market rate. It is always higher than the SBI TTBR buying rate. Using it overstates your perquisite. The difference is usually small (₹0.30–₹0.80 per dollar) but adds up on large vests.

Error 2: Using the TT Selling Rate instead of Buying Rate

TT Selling Rate (what you pay when buying USD to remit abroad) is higher than TT Buying Rate by approximately ₹0.50–₹1.50 per dollar. A perquisite calculated at the Selling Rate is overstated.

Error 3: Using the wrong date

The TTBR must be for the vest date — the date shares are released and the perquisite is recognised, per your plan documents. Not the sale date (sell-to-cover), not the settlement date, not the date the proceeds hit your account. Many platforms show multiple dates per vest event; use the "release date" or "vest date" in the transaction history.

Error 4: Using a weekend or holiday rate

SBI does not publish rates on Saturdays, Sundays, or public holidays. If your vest date falls on a non-business day (unusual but happens when US and Indian market calendars diverge), use the last published rate before the vest date.

Error 5: Recomputing a perquisite that Form 16 already shows

Once Form 16 has been issued with a specific perquisite figure, that figure is what your employer has reported to the IT Department. If you recompute with your own TTBR and get a different number, filing a different figure in ITR-2 creates a mismatch. If the Form 16 number is wrong, request a revised Form 16 from your employer — don't self-correct in your ITR-2 without a corrected Form 16.

What happens if SBI TTBR changes significantly between vest dates?

RSU holders who vest quarterly see four different TTBR rates per year — one for each vest date. If INR weakens significantly against USD during the year (TTBR rises), your later vests generate higher perquisites than your earlier vests even at the same USD stock price. Conversely, INR strengthening reduces later vest values.

The FY2026-27 context: The INR/USD rate has been relatively stable in the ₹83–₹85 range through early 2026. For advance tax planning, the TTBR on future vest dates is unknown. Conservative approach: use the current TTBR as your estimate for future vests. If INR weakens significantly before December, your actual perquisite will be higher than estimated and you may need to top up at the December 15 or March 15 installment.

Worked example: Full vest-to-ITR calculation using SBI TTBR

Facts:

• Microsoft engineer in Bangalore
• 25 MSFT shares vested on August 15, 2026
• MSFT closing price on August 15: $422.50
• SBI TTBR on August 15, 2026: ₹83.80

Step 1: Perquisite calculation

Perquisite = 25 × $422.50 × ₹83.80
           = $10,562.50 × ₹83.80
           = ₹8,85,135

Step 2: TDS (assuming income above ₹50 lakh — 10% surcharge bracket)

Tax rate = 30% + 10% surcharge + 4% cess = 34.32%
TDS = ₹8,85,135 × 34.32% = ₹3,03,759

Employer sells enough MSFT shares to cover ₹3,03,759 and remits to IT Department.

Step 3: Form 16 / Form 12BA

Form 12BA shows:

• Date of vest: August 15, 2026
• Shares: 25
• FMV (USD): $422.50
• Exchange rate (SBI TTBR): ₹83.80
• Perquisite (INR): ₹8,85,135

Step 4: ITR-2 filing (March 2027)

• Schedule S → Salary including perquisites: includes ₹8,85,135
• Schedule FA → MSFT holding valued at TTBR on peak date and Dec 31
• Schedule CG → If any MSFT shares were sold, capital gains computed with INR cost basis = FMV at vest × TTBR on vest date

Rovia's SBI TTBR lookup tool

For convenience, Rovia maintains a daily-updated SBI TTBR lookup that shows:

• Today's SBI TT Buying Rate for USD
• The previous 30 days of historical rates
• A perquisite calculator: enter shares and USD price, get the INR perquisite instantly

If you're running the calculation for multiple vest dates, the Schedule FA generator applies the correct TTBR for each vest date automatically and outputs the Schedule FA table in ITR-2 format.

SBI TTBR for ESPP calculations — a separate event with its own date

RSU perquisites use the TTBR on the vest date. ESPP perquisites use the TTBR on the ESPP purchase date — which is the last day of each offering period (June 30 or December 31, or the nearest business day).

The perquisite calculation for ESPP under Section 17(2):

ESPP perquisite (INR) = (FMV at purchase date − price paid) × shares × SBI TTBR on purchase date

The FMV at purchase date is the market closing price of the stock on the ESPP purchase date (not the offering period start date). Your employer uses this date's TTBR for the perquisite calculation, which appears in Form 12BA.

ESPP cost basis for capital gains uses the same date:

INR cost of acquisition = FMV at purchase date × shares × SBI TTBR on purchase date

Both the perquisite and the capital gains basis reference the same date — the ESPP purchase date — and the same TTBR. This is different from the RSU workflow, where the vest date is the reference for both.

The lookback does not change the rate: If your ESPP purchase price was based on 85% of a price from 24 months ago (as with Adobe's plan), the TTBR still comes from the purchase date, not from the 24-months-ago start date. The lookback determines the price you pay; the current date's TTBR converts that to INR for the perquisite and cost basis.

What happens when INR depreciates significantly between vest dates

For quarterly-vest companies, a material INR depreciation during the financial year (TTBR rising from ₹83 to ₹87 over 12 months) changes the perquisite calculation across quarters — even if the stock price in USD is unchanged.

Advance tax estimate revision scenario:

• April vest: 50 MSFT shares × $420 × ₹83.00 = ₹17.43 lakh
• May to August: INR weakens; TTBR moves to ₹86.50
• August vest (same shares, same USD price): 50 × $420 × ₹86.50 = ₹18.17 lakh
• Difference: ₹74,000 more perquisite in August vs April — purely from TTBR movement

If you estimated your full-year perquisite in April using ₹83 TTBR, and INR depreciates to ₹86.50 by the later vests, your actual perquisite will be higher than estimated. Your advance tax installments (based on the lower estimate) may undershoot the actual liability.

Practical approach: Use a conservative (slightly weaker) TTBR assumption when estimating full-year income for advance tax. If TTBR is ₹84 today, estimate at ₹85–₹86 for your advance tax calculation. This creates a small buffer against INR depreciation during the year. If INR strengthens instead (TTBR falls), you'll have overpaid advance tax — which is a credit against your final ITR-2 liability.

The 234C exception does not help with TTBR surprises: Section 234C only exempts capital gains arising after the installment date. It does not exempt perquisite income — all RSU perquisite income (regardless of when the vest occurs in the year) must be included in advance tax installments on schedule. If the December vest produces a larger perquisite than expected due to INR depreciation, the December 15 installment must cover the 75% threshold including that estimate.

Form 12BA — the document that contains your TTBR history

Form 12BA is part of your annual Form 16, prepared by your employer's payroll team. It lists every perquisite event in the financial year, including the TTBR applied to each.

What to look for in Form 12BA:

Column	What it contains
Date of allotment/exercise	Vest date (RSU) or purchase date (ESPP)
No. of shares	Shares vested or purchased
FMV at allotment (in USD or INR)	FMV per share on the date
Exchange rate	SBI TTBR applied by your employer
Perquisite value (INR)	Shares × FMV × exchange rate

How to verify each entry:

1. Note the vest/purchase date from the Form 12BA row.
2. Look up the SBI TTBR for that date (SBI historical forex rates page).
3. Multiply: shares × USD price × your looked-up TTBR.
4. Compare to the Form 12BA perquisite value.

Small differences (under ₹0.50 per dollar) are normal. Large differences may indicate the employer used a different USD price (VWAP vs closing price) or a different date. These are worth resolving with your employer before filing ITR-2 — the Form 16 value feeds directly into your Schedule S income computation.

What to do if Form 12BA is wrong:

1. Identify the specific entry and the discrepancy (date, shares, rate, or price).
2. Email your employer's HR or payroll team with the specific vest event details.
3. Request a revised Form 12BA and an amended Form 16 if needed.
4. The corrected Form 16 triggers a revised TDS entry in 26AS after your employer files a correction.
5. File ITR-2 only after the corrected 26AS reflects the revised TDS.

Do not self-correct the Form 16 perquisite in your ITR-2 without a corrected Form 16 — this creates a mismatch between your return and the employer's TDS filing.

Summary: what to remember about SBI TTBR

Question	Answer
What rate to use?	SBI TT Buying Rate (not selling rate, not mid-rate)
Which bank?	State Bank of India only (specified by Rule 26)
Which date?	Vest date for RSUs; purchase date for ESPP; receipt date for dividends
Where to find it?	SBI website → Forex Rates; FBIL for cross-reference
What if it's a holiday?	Use the last published rate before the vest date
What if Form 16 used a different rate?	Use the Form 16 figure; request correction from employer if materially wrong
Does it apply to dividends?	Yes — TTBR on dividend receipt date
Does it apply to Schedule FA?	Yes — TTBR for peak value and Dec 31 closing value
Does it apply to ESPP?	Yes — TTBR on the ESPP purchase date
What if INR moves between vests?	Revise your advance tax estimate using updated TTBR

The SBI TTBR is not a complex concept — it is one specific number, published once a day, applied consistently. The reason it trips people up is that it appears in multiple places (payslip, Form 16, Form 12BA, Schedule FA, Form 44) without always being explained. Every one of those is the same number: the SBI Telegraphic Transfer Buying Rate for USD on the relevant date.
