Why is Tax Collection Low and How to Improve It?

India's tax-to-GDP ratio sits at about 11.7%, well below the OECD average of 34% and lower than peers like Brazil, South Africa, and Vietnam. That gap is the single biggest drag on government spending power, and it shapes every conversation about fiscal policy and budget explained India.

The gap is not because Indians pay no tax. It is because the system collects narrowly and inefficiently. Fixing it does not need a higher rate; it needs a wider, smarter base.

Why the collection ratio matters more than the rate

A higher tax-to-GDP ratio gives the government room to fund roads, schools, and hospitals without piling on debt. India's fiscal deficit is high partly because tax revenue cannot fund routine spending, let alone capital investment.

Most rich countries cleared the 25% tax-to-GDP mark long before they became developed. India has been stuck near 11% for over a decade, even though formal employment, digital payments, and corporate profits have all risen.

The five real reasons tax collection stays low

Get past the headlines and the diagnosis becomes specific.

• Narrow direct-tax base: only about 6% of Indians file a tax return, and barely 2% pay any positive tax
• Cash economy carve-outs: small traders, landlords, and services still operate largely outside the formal trail
• Agriculture exemption: agricultural income is constitutionally untaxed, even when it crosses crores in commercial farming hubs
• Aggressive exemptions: hundreds of deductions, rebates, and exemptions in both direct and indirect tax shrink the effective base
• Litigation backlog: nearly 12 lakh crore rupees worth of tax demand is locked in disputes at various levels

Each of these is fixable, but each fix needs political capital, not a budget tweak.

What the data actually shows

The Economic Survey published yearly on incometax.gov.in tells a stark story. Personal income tax now contributes more than corporate tax in absolute terms, even though formal corporate profits are at record highs.

That inversion is unusual globally. It means salary earners are over-represented in the tax base while business profits and capital gains are systematically under-collected. The composition is the problem more than the quantum.

India does not have a high-tax problem. It has a narrow-base, low-compliance, high-litigation problem. Solving any one of these adds more revenue than a 1% rate hike ever could.

How the government has tried to fix it

Three reform tracks have moved over the last decade.

The Goods and Services Tax (GST) replaced a patchwork of state and central indirect taxes with a single unified tax. Compliance has improved year on year, and monthly GST collections crossed 1.7 lakh crore rupees regularly in 2024.

Corporate tax was cut from 30% to 22% in 2019 to attract investment. Collections dipped initially but recovered as profits expanded.

The faceless assessment scheme removed the discretion of the local assessing officer, cutting one layer of harassment and one layer of corruption. Honest taxpayers now hear from the department less often, while the data-driven net catches genuine evaders better.

What still needs to change

Three sharper moves would deliver more than incremental change.

• Bring presumptive taxation up to date. The presumptive scheme for small businesses still uses 8% deemed profit, which has not been revisited even as digital invoicing makes real profit visible.
• Tax agricultural income above a threshold. Most countries tax farm income above a clear floor. The current full exemption is a leakage point that genuine farmers do not need.
• Compress the litigation pipeline. A one-time settlement scheme with limited interest waiver could unlock several lakh crores from frozen disputes.

Why GST data is the most underused tool

Every GST invoice carries the supplier's and buyer's GSTIN. That is a near-real-time map of business activity. Used correctly, this data lets the income-tax department spot under-reported revenue without sending a single notice.

Some of this is already happening through Annual Information Statements, where high-value transactions show up automatically in your tax return. Expanding the scope would shift compliance from voluntary to almost automatic for the formal sector.

What this means for ordinary taxpayers

If reforms move the tax base wider, salary earners do not have to keep carrying the load alone. The fairest fix is not a higher slab on the salaried class but a smaller exempt class.

Watch the budget every year for two specific signals: changes to presumptive taxation thresholds, and any move to tax non-agricultural income masquerading as farm income. Those small lines do more than the headline rate changes.

Frequently asked questions

Why is India's tax-to-GDP ratio so much lower than other countries?
The base is narrow, agricultural income is exempt, and a large share of activity stays in the cash economy. The rate is not the bottleneck.

Will higher tax rates fix the problem?
No. Higher rates push activity further out of the formal net. Wider base and tighter compliance work better than a rate hike.

How much tax revenue is locked in disputes?
Roughly 12 lakh crore rupees is in active or frozen tax litigation across various authorities and courts.
