Online Sellers & Influencers: Which Tax Filing Method? Deep Dive into Income Types 40(2) vs 40(8) and Optimal Expense Deduction Strategies

Online Sellers & Influencers: Which Tax Filing Method? Deep Dive into Income Types 40(2) vs 40(8) and Optimal Expense Deduction Strategies

In the digital age where anyone can generate income through online channels, careers as "online sellers" and "Influencers/KOLs" have gained tremendous popularity. However, with income comes the inevitable: "taxes."

Many may be confused about income classification. Should you claim the flat-rate or actual expense deduction method to maximize tax savings? Choosing the wrong classification or incorrect deduction method not only costs you money but could lead to penalties and surcharges from the Revenue Department.

This article from Orbit Advisory provides an in-depth analysis of income classification under Thailand's Revenue Code specifically for these two professions, with detailed expense deduction comparisons and clear examples. This enables you to plan and file taxes with complete confidence and 100% accuracy.

Decoding Income Types: Influencer vs. Online Seller

Under the Revenue Code, personal income is classified into different categories, directly affecting the allowable expense deduction rates. For these two professions, classification works as follows:

1. Influencer, KOL, Content Creator, Product Reviewer

Generally, influencer income from product reviews, promotional content creation, or brand ambassador work falls under Section 40(2) Assessable Income of the Revenue Code.

Section 40(2): Income from employment, position held, or work performed for others, whether as fees, commissions, discounts, work subsidies, meeting allowances, gratuities, bonuses, housing allowances, or any money, property, or benefits received due to employment, position, or work performed.

The essence of 40(2) is income derived from "using personal labor or skills" to "perform work for others" without inventory costs like selling products. Examples include leveraging fame, creativity, and time to deliver work to clients.

2. Online Seller (E-commerce Merchant)

Income from online product sales, whether buy-and-sell (trading), self-manufactured goods, or pre-order systems, qualifies as Section 40(8) Assessable Income under the Revenue Code.

Section 40(8): Income from business, commerce, agriculture, industry, transportation, or any other activity not specified in (1) through (7).

The essence of 40(8) is income from "business operations" aimed at profit, involving product investment, clear cost of goods sold, and inventory risk—distinct from service-based work emphasizing labor.

💡 Special Case: If an influencer receives review compensation (40(2) income) while also selling their own brand products (40(8) income), tax filing must show both income types separately, with expense deductions claimed according to each category's conditions.

Comparing Expense Deductions: Flat Rate vs. Actual—Which is Better?

Once income type is determined, the next critical step is choosing the expense deduction method, which significantly impacts tax calculation. The law allows two deduction methods:

Flat-Rate Deduction Percentages by Law

• Income Type 40(2): Deduct 50% of income, capped at 100,000 baht maximum
• Income Type 40(8): Deduct 60% of income (no maximum cap)

Note the clear differences, especially the 100,000 baht cap for type 40(2), a critical threshold making high-earning influencers consider actual expense deductions.

Case Studies: Clear Calculation Examples

To better understand, let's examine comparative calculations between these two methods:

Example 1: Khun Aim (Influencer)

Khun Aim is a Beauty Blogger earning 1,500,000 baht annually from product reviews (40(2) income), with properly documented actual expenses totaling 350,000 baht.

• Method 1: Flat-Rate Deduction
• Calculate 50% of income: 1,500,000 x 50% = 750,000 baht
• ⚠️ However, law sets maximum cap at 100,000 baht
• Therefore, Khun Aim can only deduct 100,000 baht

• Method 2: Actual Expense Deduction
• Khun Aim has documented expenses totaling 350,000 baht
• Therefore, Khun Aim can deduct 350,000 baht

✅ Summary for Khun Aim: Choosing actual expense deduction results in lower net taxable income (1,150,000 baht vs 1,400,000 baht), significantly reducing tax liability.

Example 2: Khun Boy (Online Seller)

Khun Boy sells fashion apparel online, earning 3,000,000 baht annually (40(8) income). His costs including COGS, packaging, shipping, and online marketing total 1,650,000 baht.

• Method 1: Flat-Rate Deduction
• Calculate 60% of income: 3,000,000 x 60% = 1,800,000 baht
• Type 40(8) has no maximum cap, so full amount is deductible

• Method 2: Actual Expense Deduction
• Khun Boy has documented costs and expenses totaling 1,650,000 baht

✅ Summary for Khun Boy: Choosing flat-rate deduction is more beneficial, allowing deduction of 1,800,000 baht—higher than actual expenses (1,650,000 baht), resulting in lower tax liability.

⚠️ Warnings and Risks: Consequences of Incorrect Tax Filing

Incorrect income classification or inappropriate expense deduction methods without proper documentation may result in Revenue Department reassessment with penalties and surcharges. Legal penalties include:

• Criminal Penalties:
• Failure to file P.N.D.90/94 by deadline: Fine not exceeding 2,000 baht
• Intentional tax evasion: Possible imprisonment and fines up to 200,000 baht
• Surcharges:
• Non-filing: Surcharge of 2 times the tax due
• Filing but underpayment: Surcharge of 1 time the deficit amount
• Additional Interest:
• Must pay at 1.5% per month on tax due, calculated from deadline until full payment

Therefore, understanding and proper compliance from the start is essential.

Summary and Recommendations

Tax planning for online sellers and influencers begins with correct income classification (40(8) for sales, 40(2) for services), followed by comparing expense deductions between flat-rate and actual methods to choose the most tax-efficient approach for your cost structure.

• Influencers: If annual income exceeds 200,000 baht, consider maintaining documentation for actual expense deduction, as the flat rate is capped at 100,000 baht.
• Online Sellers: If your COGS and operating expenses are less than 60% of sales, flat-rate deduction is simpler and more beneficial. However, if costs exceed 60%, maintaining documentation for actual deductions saves more tax.

Frequently Asked Questions (FAQ)

Q1: At what income level must I register for VAT? A: If your annual revenue (before expenses) from selling goods or providing VAT-subject services exceeds 1.8 million baht, you must register as a VAT operator and collect 7% VAT from customers for remittance to the Revenue Department.

Q2: Can personal expenses like coffee or meals be deducted as actual expenses? A: No. Deductible expenses must be "directly related and necessary" to business operations only, such as raw materials, advertising, office rent, phone and internet (business portion only).

Q3: What's the difference between P.N.D.94 and P.N.D.90? A: P.N.D.94 is the half-year personal income tax return for income types 40(5) through 40(8) earned in the first six months (Jan-Jun), due by September. P.N.D.90 is the annual return for all income types earned throughout the tax year, due by March of the following year.

Q4: If I have both review income (40(2)) and online sales income (40(8)), how do I file? A: You must file both income types together in the same P.N.D.90 form, but calculate expense deductions separately for each income type. For example, 40(2) income gets 50% flat rate (capped at 100,000 baht) and 40(8) income gets 60% flat rate (no cap), or choose actual deduction for either type if documentation is complete.

Q5: When is the annual tax filing deadline? A: For annual tax filing (P.N.D.90):

• Paper filing at Revenue Office: By March 31 annually
• Online filing via Revenue Department website: Extended to approximately April 8-10 annually (verify exact deadline each year)
