Old vs new tax regime for RSU and foreign income holders (2026)

India's new tax regime is the default from FY 2024-25. For most salaried employees in India, it's also the better choice — lower slab rates, less paperwork. But if you receive RSU vesting income, US dividends, or a foreign component to your compensation, the decision is not obvious. The old regime's deductions can still win.

This page focuses specifically on the foreign income angle — US stock dividends, capital gains from US equity, and RSU perquisites from foreign employers. For a general RSU income comparison without the foreign income layer, see the full old vs new regime RSU guide.

The regime basics

Old regime — higher slab rates, but you keep all deductions: HRA, 80C (₹1.5 lakh), 80D (health insurance), 80CCD(1B) (NPS top-up ₹50,000), home loan interest, LTA, and more.

New regime — lower slab rates, but almost all deductions are gone. Only the ₹75,000 standard deduction on salary survives from FY 2024-25.

New regime slab rates (FY 2026-27):

The new regime also gives a full rebate under Section 87A up to ₹12 lakh total income (nil tax liability below ₹12 lakh before surcharge and cess). This rebate does not apply to special-rate income like long-term capital gains.

How RSU income interacts with the regime

When your RSUs vest, the difference between the fair market value on vest date and your acquisition cost (usually zero for grants) is treated as a perquisite — salary income. This gets added to your gross salary.

The critical point: RSU perquisites push your total income into higher slabs. A ₹20 lakh base salary plus ₹15 lakh in RSU vesting = ₹35 lakh taxable income before deductions. At that level, slab rates under the old regime (30%) and new regime (also 30% above ₹24 lakh) converge — so the deductions available under the old regime become the deciding factor.

What deductions actually move the needle at ₹35 lakh+

• 80C — ₹1.5 lakh (PF, ELSS, PPF, life insurance): always worth claiming
• 80D — ₹25,000–₹50,000 (health insurance): standard for anyone with a family floater
• 80CCD(1B) — ₹50,000 (NPS top-up): an additional ₹50,000 beyond the 80C ceiling
• 80CCD(2) (employer NPS contribution): available under both regimes — up to 10% of basic salary for private sector employees; one of the most valuable deductions surviving the new regime
• HRA (if paying rent): can be significant in metro cities — 40–50% of basic salary
• Home loan interest — up to ₹2 lakh (Section 24b): only applicable if you have a loan
• Standard deduction on salary — ₹75,000 (available in both regimes from FY 2024-25)

A single employee with no HRA, no home loan, maxing 80C + 80D + NPS: roughly ₹2.25 lakh in deductions beyond the standard deduction. At 30%, that saves ≈₹67,500 in tax versus the new regime at the same income level.

US dividends and foreign income: how each regime treats them

US stock dividends (25% withheld at source under Article 10(2)(b) of the India-US DTAA with a W-8BEN; the 15% rate under Article 10(2)(a) is only for companies owning ≥10% of voting stock) are added to your total income in India and taxed at slab rates under whichever regime you choose. The 25% US withholding becomes a Foreign Tax Credit (via Form 67 for AY 2026-27, Form 44 from AY 2027-28) to offset your Indian tax liability.

How the FTC interaction differs by regime

The tax on foreign dividends themselves is the same category under both regimes — ordinary income at slab rates. The key difference:

1. Marginal rate on dividends: If your total income is above ₹24 lakh, both regimes apply 30%. Below ₹24 lakh, the new regime's lower intermediate slabs can reduce tax on dividend income specifically.

2. Foreign Tax Credit interaction: The FTC from US withholding is limited to the Indian tax payable on that income. If the old regime gives you a lower effective rate on dividends (because deductions reduce your taxable income, bringing more dividend income into a lower slab), the FTC offset works more efficiently.

3. Practical impact: On ₹1.5 lakh of US dividends where US withholding is ₹37,500 (25%), if your Indian marginal rate is 30%, you owe ₹45,000 Indian tax but get ₹37,500 FTC → net Indian tax on dividends = ₹7,500. If deductions under the old regime bring your marginal rate to 20% on this income, you owe ₹30,000 but still get ₹37,500 FTC → net Indian tax = ₹0. The old regime can eliminate Indian tax on foreign dividends at lower income levels.

Capital gains from US stocks: both regimes, same rates

Capital gains from US stocks follow their own rate schedule regardless of which income tax regime you choose:

• STCG (held < 24 months): Taxed at your ordinary income slab rate — so the regime matters here; lower new-regime slabs at certain income levels reduce STCG tax
• LTCG (held ≥ 24 months): Taxed at a flat 12.5% under Section 112, no indexation — identical under both regimes; the regime choice does not affect LTCG on US stocks

The key insight: LTCG from US stocks is regime-neutral. You pay 12.5% either way. Only STCG is affected by your slab rate.

However, capital gains are still added to your gross total income for surcharge determination — and the surcharge rates differ meaningfully between regimes at very high income levels.

Surcharge: where the regimes diverge most at incomes above ₹1–5 Cr

For RSU holders with total income (salary + RSU perquisite + foreign income) between ₹1 crore and ₹5 crore, the surcharge calculation is one of the most consequential differences.

Old regime surcharge rates:

New regime surcharge rates:

The new regime caps surcharge at 25% for all income levels. Under the old regime, surcharge above ₹5 Cr is 37%, making the effective marginal rate 42.74% (30% + 37% surcharge + 4% cess), versus 39% under the new regime (30% + 25% surcharge + 4% cess).

For RSU holders with exceptionally large vesting events (total income crossing ₹2–5 Cr), the new regime's capped surcharge can save ₹5–15 lakh, even after losing all deductions. This is the one scenario where high-income RSU holders clearly benefit from the new regime.

NPS 80CCD(2): the deduction that survives in both regimes

Section 80CCD(2) — the employer's NPS contribution on your behalf — is deductible under both the old and new regime. If your employer contributes to NPS (or you can structure compensation to include an employer NPS contribution), you can deduct up to 10% of basic salary + DA under the new regime.

For a ₹30 lakh basic salary, that's ₹3 lakh in additional deductions — worth ₹90,000 in tax savings at 30%. Combined with the ₹75,000 standard deduction, the new regime's effective deductions can reach ₹3.75 lakh+ for employees with employer NPS contributions.

The breakeven analysis with foreign income included

The old regime wins when your total available deductions (beyond standard deduction) exceed approximately ₹2 lakh at a 30% marginal rate. For most RSU holders with PF contribution, health insurance, and any NPS participation, this threshold is crossed easily.

When you add foreign income:

• Foreign dividends boost total income, pushing more into the 30% slab where old regime deductions are worth more
• LTCG from US stocks does not change the breakeven (12.5% flat under both regimes)
• STCG from US stocks is slab-rate income — at ₹35 lakh+ total income, both regimes have you at 30%, so the deductions still drive the decision

The new regime wins when:

• Your total income crosses ₹5 Cr and the surcharge cap matters more than deductions
• You have no HRA claim, no 80C investments, no home loan
• You are a freelancer or consultant wanting simplicity

Worked example: foreign income included

Scenario: Salaried employee, ₹22 lakh base CTC, ₹10 lakh RSU vest, ₹1.5 lakh US dividends (after 25% US WHT), ₹2 lakh LTCG from US stocks sold after 24 months, paying rent of ₹25,000/month in Bengaluru.

In this scenario the old regime wins by roughly ₹1.4 lakh. Adding foreign dividends slightly widens the old-regime advantage because the FTC on dividends offsets Indian tax more efficiently when deductions bring your effective rate lower.

How to decide

1. Add up your actual claimable deductions — not theoretical maximums, what you genuinely invest and spend
2. Compute tax under both regimes on your projected total income (salary + RSU perquisite + dividends + capital gains)
3. If your total income is above ₹2 Cr, specifically check whether the new regime's surcharge cap saves more than your deductions
4. The one with lower liability wins — also factor in the compliance cost of the old regime
5. Make the choice at the start of the financial year and inform your employer (via Form 12BB) so TDS is deducted correctly

The old vs new regime calculator lets you enter your salary, RSU income, foreign dividends, capital gains, and each deduction bucket to see the comparison instantly.

One thing RSU holders often miss

RSU perquisites are taxed via TDS at vest — your employer deducts tax in the month of vesting. If your employer uses the new regime for TDS but you plan to file under the old regime at ITR time, you will get a refund. If it's the other way around, you'll have a tax demand. Align your TDS regime declaration with your ITR filing intent to avoid interest under Section 234B/234C.

For foreign employers paying RSU income not routed through an Indian payroll, ensure you are paying advance tax by March 15 on the estimated RSU + dividend + capital gains income to avoid 234B/234C interest.

The one-line version

If you have RSU income + HRA + active 80C/80D investments, run the numbers — the old regime often still wins by ₹75,000–₹1.5 lakh at income levels above ₹20 lakh. The exception: if total income exceeds ₹2 Cr, the new regime's surcharge cap can flip the math. Use the calculator to know for sure before your employer locks in the TDS regime for the year.
