Malaysia's GST and SST: Why Did Najib Push for the Consumption Tax?

On April 1, a new line appeared on the cash register.

GST 6%.

The line is short.

But it thrust Malaysia's national ledger right before every dining table, every sundry shop, and every mobile prepaid counter.

Before GST, It Wasn't Tax-Free#

Before GST, Malaysia used the SST: Sales Tax and Service Tax.

The old SST was not a value-added tax levied at every stage of a transaction that allowed businesses to claim input tax credits. It operated more like a single-stage tax levied at the manufacturing, importing, or specific service stages. When the SST returned in 2018, it also continued this dual "Sales Tax + Service Tax" framework and Customs Department enforcement guidelines. ^1,4,5

GST was different.

It was a multi-stage consumption tax: businesses collected tax at every stage of a transaction and could claim credits for input taxes paid during procurement, with the final tax borne primarily by the end consumer. Najib's government implemented the GST on April 1, 2015, at a rate of 6%, replacing the old SST. ^1,2,5

Technically, the GST was broader, more transparent, and made it much harder for transactions to stay completely outside the tax net.

Politically, it was also much more painful.

Because the people could see it.

Why Did Najib Push for GST?#

The government's argument was straightforward: the nation could not continue to rely so heavily on oil money.

The Ministry of Finance's 2015/16 Economic Report noted that oil- and gas-related revenues as a share of total revenue had dropped from 41.3% in 2009 to 30% in 2014, and were projected to drop further to 19.7% in 2015 due to plummeting oil prices. The same report stated that the implementation of GST was intended to broaden the tax base and cushion the impact of falling oil prices on government revenue. ^1,2

The deficit was also on the table.

After the 2009 financial crisis, the federal fiscal deficit reached 6.7% of GDP. By 2014, it had been brought down to 3.4%, and the target for 2015 was 3.2%. The IMF at the time also recognized that Malaysia's fuel subsidy rationalization and GST implementation were necessary steps to broaden the tax base, reduce dependence on volatile oil and gas revenues, and continue fiscal consolidation. ^1,2,3

In other words, the GST didn't just fall from the sky.

It was a choice made by a fiscal administration facing three realities: shrinking oil money, the need to reduce the deficit, and the inability to drastically slash spending overnight.

GST in the Government's Ledger#

In his 2016 budget speech, Najib presented hard numbers.

He stated that if GST were not implemented in 2016 and the country continued to rely on the old SST, the government would lose RM21 billion in revenue; the old SST could only collect RM18 billion, whereas the GST could collect RM39 billion; and the fiscal deficit would swell from a target of 3.1% to 4.8%. ^1,3

The Ministry of Finance's Economic Report also estimated that the GST would collect RM27 billion in 2015, higher than the initial projection of RM21.7 billion; from January to March of that same year, the government also collected RM7.6 billion from the old SST. ^1,3

This was the appeal of the GST for the government.

It wasn't small change.

It was a pipeline that allowed the budget to keep running, the deficit to keep shrinking, and credit rating agencies to remain confident in the country's revenue sources.

GST in the People's Ledger#

But the national ledger is not the people's wallet.

The government saw a broadened tax base.

Consumers saw a longer receipt.

Supporters of the GST would argue that many basic food items, medicines, education, and healthcare were zero-rated or exempt. The government also lowered personal and corporate income taxes and used cash aid like BR1M to cushion the blow for low-income groups. The Ministry of Finance's report did indeed list a series of GST relief measures and zero-rate adjustments. ^1,2,3

Opponents, however, argued that these technical arrangements could not alter the ordinary person's experience: when prices go up, consumers don't pause to distinguish whether it's due to the GST, exchange rates, merchant markups, transport costs, or the removal of subsidies. They only know that the same amount of money buys less.

A false narrative easily emerges here.

It is inaccurate to blame all price hikes solely on the GST.

But it is equally disingenuous to pretend the GST had no impact on the felt cost of living. The IMF anticipated at the time that the GST, subsidy rationalization, and exchange rate depreciation would cause a slight bump in inflation in 2015; the government also acknowledged the ongoing need to adjust zero-rating and assistance mechanisms. ^1,2

The Ledger Didn't Disappear After GST Was Abolished#

In 2018, Pakatan Harapan made the abolition of GST a key campaign promise.

Following the change in government in May, the standard GST rate was reduced from 6% to 0%, effective June 1. The GST was subsequently abolished, and the SST made its return on September 1. The Customs Department's MySST portal remains the official gateway for the SST system, acts, and guidelines to this day. ^4,6,5

Politically, this was highly effective.

The GST had become one of the most palpable burdens placed on ordinary voters by the Najib administration. You didn't need to understand the money trails of 1MDB, nor did you need to read PAC reports; you only needed to pick up a receipt to see that 6% line. ^1,6,5

But abolishing the GST did not make the fiscal problem disappear.

If a broader GST is replaced by a narrower SST, the government must either collect less money, find money elsewhere, cut spending, or borrow more. The fiscal debates post-2018 essentially revolve around the same problem: people don't like paying taxes, but people also demand roads, schools, hospitals, subsidies, civil servants, pensions, security, and disaster relief. ^1,2,4,5

Malaysia's Real Problem#

The GST controversy appeared to be about "whether we should have a consumption tax."

Beneath the surface, it was actually about four things.

First, the Malaysian government has long desired to provide many things: subsidies, aid, development projects, civil service remuneration, education, healthcare, and basic rural infrastructure.

Second, Malaysia's revenue often relies on unstable sources: oil, palm oil, corporate profits, one-off dividends, and asset sales.

Third, the direct tax base is not broad enough; many people earn too little to pay income tax, and many small businesses and cash transactions struggle to be fully captured in the tax net.

Fourth, public trust in government spending has been severely damaged by corruption, wastage, political appointments, and mega-scandals like 1MDB. ^1,2,3

Therefore, the GST was ultimately not just a tax issue.

It became a trust issue.

The next time around, voters saw more than just a tax.

They saw yachts, paintings, and a national ledger that became increasingly difficult to believe; by then, the issue was no longer just how much more the cash register collected, but who had spent the nation's credibility along with it.
