India's Tax System: Dual Laws Create Years of Complex Compliance
Overview

India's tax system is changing with the Income-tax Act, 2025, starting April 1, 2026. Instead of replacing the old 1961 Act, both laws will operate together for years. This dual system means taxpayers face complex compliance, must decide annually which regime to use, and understand that tax benefits depend on rebates. Staying informed is key to avoiding mistakes during this lengthy transition, which experts warn could lead to more legal disputes and higher compliance burdens.

India's Tax System: Two Laws for Years to Come

India's tax system is starting a long transition on April 1, 2026, with the new Income-tax Act, 2025. Importantly, this law won't immediately replace the old Income-tax Act of 1961. Instead, both laws will operate side-by-side for many years. This dual system is designed to allow old cases, assessments, and legal matters under the 1961 Act to be finished before they are fully retired. For taxpayers, new income and deals will follow the 2025 Act, while older matters remain under the 1961 Act. The tax department's e-filing portal will handle this parallel system, but it demands careful record-keeping to know which law applies to what. The new Act also changes how tax years are counted, aiming for clearer global alignment, though the transition itself brings challenges.

Understanding Your Tax Options: Deductions and Rebates

Taxpayers also face parallel tax rules. The 'old tax regime,' known for deductions like those under Section 80C and 80D, is not gone. It remains an option taxpayers can choose each year, meaning deduction planning is still important if they prefer it over the new system. Many people mistakenly believe all income up to ₹12 lakh is tax-free. In reality, this comes from a rebate under Section 87A, and only applies if specific conditions are met and an Income Tax Return (ITR) is filed. Experts, like those at the Bombay Chartered Accountants Society (BCAS), stress that managing this period will require more awareness from taxpayers, not less.

Risks and Litigation: What Could Go Wrong

Despite aiming for simpler tax laws, the new Act and the long period with two laws together create significant risks. Tax professionals worry about more tax disagreements and lawsuits because the rules might be unclear and navigating two legal systems is complex. The 2025 Act gives tax officers wider powers, including greater ability to search digital records, which raises privacy worries and the possibility of overreach. Critics also note that core definitions haven't changed much and powers to reopen past tax assessments remain, which have often led to disputes. While the new Act consolidates rules, reducing the number of sections, it may not simplify things without better digital systems and staff trained to handle new data. The 'unexplained credits/investments' rules, which allow for discretion, could surprise individuals with less formal financial records. Using old administrative instructions from the 1961 Act within the new law might also cause confusion and legal battles. Tax authorities’ limited ability to process advanced digital data could lead to errors, further fueling disputes.

Preparing for the Change: What Taxpayers Should Do

Moving to the Income-tax Act, 2025, requires taxpayers and businesses to be proactive and well-informed. Experts suggest making the most of deductions under the old regime before March 31, 2026. Afterwards, individuals should look at salary structuring, compare tax regimes yearly, and adjust investment plans, considering possible shifts in areas like Securities Transaction Tax (STT) and how dividends are taxed. New rules for advance tax and Tax Deducted at Source (TDS) apply from April 1, 2026, demanding careful attention. Multinational companies may see higher compliance costs as they need advanced systems for new tax rules and potential international tax effects, like those from OECD's Pillar I and II plans. The long coexistence of two tax laws means taxpayers must stay alert, seek guidance, and adapt financial plans to avoid non-compliance, penalties, and lengthy legal battles. The BCAS is holding educational sessions to help professionals and taxpayers prepare.
