The Income Tax Act 2025’s Section 34: List of Allowable and Disallowed Expenses for Claiming the Deduction

Section 34 of the Income Tax Act, 2025, is a residuary provision that allows businesses and professionals to claim deductions for all expenses not covered under Sections 28 to 33, provided they are incurred wholly and exclusively for business or profession. It lowers the total tax burden by ensuring that legal business expenses are deducted when calculating taxable income.

Section 34(1): “Any expenditure (not being an expenditure of the nature specified in sections 28 to 33, 44 to 49, 51 and 52 and not being in the nature of capital expenditure or personal expenses of the assessee), laid out or expended wholly and exclusively for the purposes of the business or profession, shall be allowed in computing the income chargeable under the head “Profits and gains of business or profession’.”

However, any expense incurred for illegal purposes, prohibited by law, or to settle legal contraventions is strictly prohibited from being claimed as a deduction.

New Tax Year vs Assessment & Previous Year : How the Income Tax Act, 2025, Simplifies the Process?

The Income-Tax (No. 2) Bill, 2025, the most significant reform of India’s tax system in over 60 years, was enacted by the Lok Sabha on August 11, 2025. A simpler, more useful framework has taken the place of the outdated Income Tax Act, 1961, which had developed into complicated legislation with more than 800 sections and countless revisions.

One of the most notable of the many changes made is the substitution of the considerably simpler “Tax Year” concept for the long-standing “Assessment Year and Previous Year” structure. This change aims to simplify tax compliance, clear up any confusion, and bring the law into accordance with international standards.

Understanding the Old Framework: Assessment Year and Previous Year

Under the 1961 Income Tax Act, income taxation revolved around two separate terms:

  1. Previous Year – This referred to the financial year in which a person actually earned income. For example, income earned between 1st April 2024 and 31st March 2025 would be the “previous year 2024-25″.
  2. Assessment Year – This was the following year in which that income was assessed and taxed. So, income earned in the previous year, 2024-25, would be taxed in the “assessment year 2025-26″.

While this system worked for decades, it often created confusion for ordinary taxpayers. Many found it difficult to understand why their income was taxed in a different year than when they earned it. Professionals and students alike had to repeatedly clarify the difference between these two terms, leading to unnecessary complexity.

The New Concept: Tax Year

The Income-Tax (No. 2) Act, 2025, introduces the “tax year” to replace both “previous year” and “assessment year”.

  • A tax year is simply the financial year in which income is earned and reported.
  • For example, if income is earned between 1st April 2025 and 31st March 2026, it will now be referred to as Tax Year 2025-26.

This means income and its taxation will be identified within the same year, avoiding the two-step process that confused many taxpayers earlier.

Why This Change Matters?

1. Simplification of Language

By using just one clear term—Tax Year—the law becomes easier for individuals and small businesses to understand. A student filing their first return or a small shop owner trying to meet deadlines no longer has to remember separate terms.

2. Better Alignment with Digital Filing

India’s tax system is moving rapidly toward digital-first administration. In an era of online filing, faceless assessments, and instant refunds, the dual-year system felt outdated. The tax year integrates neatly with digital reporting formats, reducing the chance of mistakes.

3. Global Consistency

Many countries, including the United States and the UK, follow simpler terminology like “tax year” or “fiscal year”. India’s shift not only modernises domestic law but also makes cross-border compliance easier for global businesses and professionals.

4. Reduced Litigation and Errors

The old law saw frequent disputes over the timing of income recognition, especially in cases of carry-forward losses, deductions, and set-offs. With the tax year concept, the timeline is clearer, minimising interpretational gaps.

Comparison Table: Old vs New System

AspectIncome Tax Act, 1961Income-Tax Act, 2025Implication
ConceptPrevious Year & Assessment YearTax YearSingle term simplifies understanding and reporting
Tax TimelineIncome earned in Previous Year is taxed in next year (Assessment Year)Income earned is taxed in the same Tax YearReduces confusion and aligns reporting with earning

RefundsStrict deadlines; missing ITR may forfeit refundRefunds allowed post-deadline without penaltyReduces financial loss due to procedural delays
Digital FilingPartial faceless processesFully faceless and digital-firsttransparency and reduced face-to-face interaction with authorities

Conclusion

The substitution of “Tax Year” for “Assessment Year” and “Previous Year” is more than just a visual adjustment; it is a genuine attempt to simplify India’s tax structure. The rule eliminates misunderstandings, minimises compliance errors, and improves the transparency of tax reporting by matching income with the same year of taxes.

The Income Tax (No. 2) Act, 2025, along with its digital-first procedures, simplified sections, and enhanced taxpayer rights, lays the foundation for a contemporary, technologically advanced tax system. To put it briefly, the tax year is a sign that India’s tax system is finally keeping up with the demands of rapid growth and a digital economy.
