September 2025 Tax & Reg Watchpoint

With summer holidays behind us, September brought a renewed wave of tax updates and policy shifts to tackle…

This is a glimpse of what caught my attention…and as you read the plethora of changes and consider the challenges they present especially to marketplaces and their sellers, keep in mind that only the right system can enable growth and open new markets without financial or reputational risk.

Chile

Chile is set to change its legislation regarding VAT on low-value goods in October 2025. In preparation, the tax authorities have published an insightful article aimed at businesses, explaining the upcoming changes and the rationale behind them. The article also shares data on the 10 largest platforms selling into Chile. It’s well worth reading — even for those outside the tax profession.

UK

The UK Parliament’s February 2025 publication on tax evasion in the retail sector highlighted the mandate that marketplaces strengthen checks on the establishment of sellers, as this directly impacts VAT liabilities. In response, HMRC has issued guidance defining what constitutes reasonable and appropriate checks. The guidance notes that the level of checks required may depend on the size of the platform and provides a non-exhaustive list of possible measures — including reviewing financial information, geolocation data, and the residency of directors. For a deeper dive into this topic, you can refer to a detailed blog we published last year.

Taiwan

Taiwan has issued clarifications on VAT collection for revenue generated by content creators, aligning these rules with existing regulations on cross-border electronic services. Platforms will now have an obligatory role in collecting business tax (Taiwan VAT). Interestingly, VAT appears to be due on advertising spend even when payments are made to foreign companies, as long as the content is “targeted” at Taiwanese viewers.

I may be misinterpreting some aspects, but given that content creation is rarely aimed at a single country’s audience, I wonder how the portion attributable to Taiwanese viewers will be able to be measured. If you have additional insights into these new rules, feel free to reach out. It is also worth noting that, “under the principle of simplified taxation, overseas influencers are exempt from tax registration and business tax filing.”

Extension of Scope of legislation

Mexico

Mexico is set to extend platform obligations for sellers of physical goods starting January 2026. The rules will differ depending on whether the seller is domestic or foreign, will apply to both B2B and B2C transactions, and will introduce mandatory e-invoicing alongside higher withholding tax rates on certain seller income. If your platform sells in Mexico, it is essential to review these new requirements and ensure your processes are aligned.

US Washington State

As states look for new revenue sources, sales tax is increasingly being extended to services, including live presentations. While this may seem routine outside the U.S., it represents a relatively new approach in the US, as services have only recently come within the scope of U.S. sales tax.

Colombia

Draft tax rules in Colombia propose eliminating the ‘de minimis’ exemption for low-value shipments and removing the exemption for cloud computing, hosting, and software licenses for digital content. These changes would directly impact foreign suppliers providing goods or services in Colombia.


Enforcement

Thailand

Thailand has ended its tolerance for late VAT payments. This is a significant change, as late payments can easily occur when businesses must make VAT payments globally in multiple currencies on a monthly or quarterly basis.

Lebanon

As part of its 2026 budget bill, the Lebanese government has announced a focus on fighting tax fraud as a key source of revenue generation.

Canada

The Canada Revenue Agency has updated its Voluntary Disclosures Program, offering 75% interest relief and full penalty relief for unprompted applications, and 25% interest relief with up to full penalty relief for prompted applications following CRA contact.

UK

Temu’s corporate tax position is under scrutiny in the UK, reviving a recurring debate about where corporate tax should be paid — based on the location of sales or the place of establishment.

Israël

Authorities are reviewing a large tax fraud case related to online commerce and importers.
