Most freelancers who struggle with money are not short of work. They are short of structure. Client fees, project costs, next year's tax bill and personal living money all land in one bank account, and when the app shows a six-figure balance the brain reads “rich” — even though half of it belongs to suppliers and the Revenue Department.
What follows is a money system that takes about an hour to set up and ten minutes a month to run. No accounting knowledge required, and you can start with the bank app you already have.
The real problem is the single pot
Salaried employees get this system for free without noticing. The employer withholds tax, deducts social security, pays on a fixed date, and absorbs work expenses. The money that lands in their account is genuinely theirs.
Freelancers have nobody doing that. Every transfer a client sends is a mixed lump, and separating it is your job alone. Skip it and you get the three classic symptoms: overspending in a big month, borrowing in a slow month, and scrambling for a lump sum in March despite a strong year.
The four-account structure
You do not need four banks. Most Thai banks let you open extra savings or e-savings accounts inside the app in minutes.
1. The receiving account
The only account clients pay into. Attach the PromptPay ID that appears on your invoices here. Never spend from it. Its single job is to receive and distribute. Having exactly one inbound account also makes reconciling payments against invoices dramatically easier.
2. The tax and contributions account
Every time money arrives, move a fixed percentage here immediately. This money is not yours — you are holding it for the Revenue Department. If you are VAT registered, the 7% you collect from clients belongs here too.
3. The business cost account
Software, coworking desk, subcontractors, travel to client meetings, equipment. Keeping these separate means that at year end you can answer the deduction question — lump sum or actual expenses — from real numbers rather than a guess.
4. The personal account
Where the “salary” you pay yourself lands. Every baht here is genuinely free to spend, because tax and costs were already removed upstream.
How much should you pay yourself?
One rule: base it on the average, not on your best month.
Pull the last twelve months of income, subtract what you set aside for tax and business costs, divide by twelve, then multiply by 0.8. That number is your salary, paid to yourself on the same date every month. The 20% you held back accumulates in the receiving account to cover thin months.
If you are new and lack twelve months of history, use whatever you have and revise quarterly. The point is that your personal life gets a stable number to plan around even though your income never is.
How much tax should you reserve?
Real numbers, for income under Section 40(8) with the 60% lump-sum deduction.
On 1,200,000 THB a year
- 60% deduction = 720,000, leaving 480,000
- Personal allowance of 60,000 → net income 420,000
- Tax: first 150,000 exempt, next 150,000 at 5% = 7,500, remaining 120,000 at 10% = 12,000
- Total tax 19,500 THB, against 36,000 already withheld at 3% → a refund of roughly 16,500
On 2,000,000 THB a year
- 60% deduction = 1,200,000, leaving 800,000, minus 60,000 allowance → 740,000
- Tax: 7,500 + 20,000 (10% band) + 36,000 (15% band) = 63,500 THB, against 60,000 withheld → almost exactly level
The pattern matters. At around a million baht of revenue, 3% withholding usually exceeds your real bill, so you get money back. As revenue climbs, 3% stops being enough and you owe the difference at filing time.
A safe working rule: reserve 10% of gross receipts if you expect under 1.5 million this year, and 15–20% above that. Over-reserving is a good problem. And remember that 1.8 million baht of annual revenue is the VAT registration line, which changes both the prices you quote and the paperwork you file every month.
The mistake that hurts most: VAT collected from clients is not income. You are collecting it on behalf of the state. Spend it and the month you file PP.30 becomes very painful.
A six-month buffer, built from every invoice
The target is six months of essential spending — rent, food, transport, insurance, loan payments. Not your full lifestyle.
The method that actually works is deduction at source, not willpower at month end. Move 5–10% of every client payment into the buffer on the day it arrives. Small and every time beats large and occasionally.
Freelancers need a deeper buffer than employees, and not mainly because of dry spells. It is because late payment is normal. Work finished this month may be paid two months from now. A buffer is what stops you accepting underpriced work out of desperation.
When a month collapses
Cut in this order:
- Reduce your own salary temporarily — reduce, not eliminate
- Cut pausable business costs: unused tools, courses not yet started
- Draw from the buffer
- Never touch the tax account. That money already has an owner; borrowing from it just moves the crisis to March
Before you reach step three, check where the money actually went. Often the problem is not a lack of work but three unpaid invoices nobody has chased.
Four numbers to check every month
- Real available cash — personal plus business cost accounts, excluding the tax account
- Outstanding receivables — invoices issued but unpaid, split by how many days overdue
- Year-to-date revenue — measured against the 1.8 million VAT line so registration never surprises you
- Tax account balance — against your estimated bill; if you are behind, raise the percentage starting next month
Ten minutes with these four answers nearly every decision you have to make that month.
The operating rhythm
- Every payment received: distribute from the receiving account, and mark the invoice as paid
- Every week: review outstanding invoices and email anything past due
- Every month: pay yourself, check the four numbers, file expense receipts
- Every quarter: revisit your salary, revisit your rates, and confirm you have collected every withholding tax certificate
- Every year: compare lump-sum against actual expense deduction, and plan allowances before December rather than in March
Start today, in 60 minutes
Open three sub-accounts. Point your invoice PromptPay ID at the receiving account. Average whatever income history you have, set your salary, and fix your tax and buffer percentages. That is the whole setup — the system starts working on the next client transfer.
The rest is consistency, which gets far easier when quotations, invoices, receipts, overdue balances and income all live in one place. That is precisely what MANA is built to do for Thai freelancers.
