Section 43A of Income Tax Act: Adjustment for Foreign Exchange Fluctuations

byPaytm Editorial TeamAugust 31, 2025
When you buy things from other countries using foreign money, the value in Indian rupees can change because exchange rates go up or down. Section 43A helps businesses add or take away that difference from the thing’s cost, so taxes are fair. This article explains how it works, why it matters, and how to do it the right way.
Professional Tax

Section 43A ensures businesses adjust the cost of things (like machinery) bought from abroad if the exchange rate changes between purchase and payment. It’s fairer than pretending the price stayed the same.

Applicability to taxpayers dealing with foreign exchange transactions:
Only when you import assets (not buy them in India) and pay in foreign currency—like dollars or euros.

Understanding Foreign Exchange Fluctuations

What are foreign exchange fluctuations?
That’s when the value of one country’s money changes compared to another. For example, ₹80 for $1 instead of ₹75.

Why they impact tax and accounting treatment:
Because what you paid in rupees can change, the cost of the item changes—so depreciation and taxes must adjust too.

Applicability of Section 43A

Eligible taxpayers and businesses:
Businesses importing assets and paying in foreign currency.

Types of assets covered (capital assets, machinery, plant, etc.):
Capital assets—like machinery, buildings, tools—bought from outside India.

Situations when adjustments are required:
Only when liability in rupees changes due to exchange fluctuations and you actually make the payment.

Key Provisions of Section 43A

  • Adjustment of actual cost of assets acquired from abroad:
    If the exchange rate rises, you add the extra rupees; if rate falls, you subtract the saved rupees from the asset’s cost.
  • Treatment of repayment of foreign-currency loans:
    Same as above—adjust cost when you repay in foreign currency, if rates change.
  • Depreciation implications after adjustments:
    Higher cost means higher depreciation, and vice versa.

Conditions for Adjustment under Section 43A

  1. Loan or liability must be in foreign currency to buy the asset from abroad.
  2. The exchange rate must change between purchase and payment time.
  3. Payment must actually happen in that previous year—not just an accounting entry.
  4. Assets must be used for business in India.

Method of Adjustment

  • Increasing or decreasing the actual cost of asset:
    Example: Bought machinery for $100,000 at ₹75 → ₹75 lakh. Paid later at ₹80 → ₹80 lakh. Add ₹5 lakh to cost.
  • How exchange difference affects depreciation:
    Depreciation is now based on ₹80 lakh, not ₹75 lakh—providing a tax benefit or burden depending.
  • Treatment of gains and losses in P&L account:
    It isn’t counted as profit or loss. It’s added to or deducted from the asset’s cost instead of showing in profit & loss immediately.

Amendments and Recent Changes

  • Section 43A originally came into effect in 1967.
  • In 2003, the law was clarified: adjustments apply only at the time of actual payment, not when you note it on paper.
  • The section continues to apply only to imported assets—so assets bought in India, even with foreign loans, don’t qualify.
  • No major changes since—but always check the latest income tax rules.

Importance of Section 43A for Businesses

  • Ensures accurate asset valuation in books.
  • Impacts tax liability via depreciation on the right cost.
  • Aligns with Indian Accounting Standards and keeps audit clear.

Common Challenges and Issues

  • Complexity in calculation: Need exact rates on payment dates vs. purchase dates.
  • Unrealized vs. realized fluctuations: Unrealized (on paper) differences don’t count—only realized upon payment.
  • Risk of non-compliance: Tax audits often scrutinize these adjustments—documents must back them up.

Expert Tips for Taxpayers

  • Keep clear documents showing purchase cost, exchange rates, and actual payment.
  • Use professional help, like a CA familiar with Section 43A.
  • Ensure accounting treatment matches tax treatment—avoid mismatches in books vs. tax filings.

Conclusion: Section 43A helps keep things fair when currency rates change between buying and paying for imported assets. It lets businesses adjust the asset’s cost instead of treating the difference as immediate profit or loss. While the concept is simple, accurate calculation and documentation are vital. With smart handling and expert help, businesses can use Section 43A to better reflect real costs and stay audit-safe.
