Budget (Government) vs Budget (Accounting)

One person thinks of "the appropriation legally approved — how much spent, how much remains, did we hit the plan?" Another thinks of "Budget vs Actual in the management report — by how much did expense exceed plan this month?" Yet another thinks of "the disclosure of budget vs actual in the financial statements per IPSAS 24."

All three interpretations are correct in their own context — the problem is that when they meet and use the same word, they often talk past each other.

This article is not a "Public vs Private" comparison — it is an academic study of the word "budget" used in 3 functionally distinct contexts. Both public and private sectors can use any of these meanings — but if sender and receiver don't agree on which context, communication breaks down immediately.

1. "Budget" Is a Polyseme

In linguistics, a polyseme is a word with multiple related meanings used in different contexts. "Budget" — both in English and Thai (งบประมาณ) — is clearly polysemous: the same word appears in public law, management accounting textbooks, and international accounting standards.

Before the three main meanings, here are common terms often confused with "budget":

Words frequently used interchangeably

Term	Actual meaning	Common confusion
Budget	Forward-looking financial plan	—
Financial Statements	Backward-looking report of past results	"Looking at the company's latest statements" usually means FS, not budget
Balance Sheet / Income Statement	Components of FS — current position / period results	In Thai, the word "งบ" can refer to either
Estimate / Forecast	Projected number — not formally approved	Budgetary Procedures Act uses "Revenue Estimate" + "Expenditure Budget" — revenue is estimated, expenditure is authorized
Allocation / Limit	Ceiling allocated to a line item or project	"Project budget THB 500K" usually means an allocation, not a master budget

English near-synonyms that aren't synonymous

Word	Meaning	Context
Budget	Financial plan — generic	All 3 contexts
Forecast	Projection — often updated mid-period, no formal approval	Management accounting
Plan	Broad — includes budget + non-financial plans	General
Appropriation	Legal authority to spend — legally binding	Public sector
Allocation	Amount allocated to a unit/line	General (public & private)
Allotment	Release of funds from appropriation to agency in tranches	Public sector (esp. US Federal)
Encumbrance / Commitment	Reserved obligation — held aside before payment	Public sector + large procurement

With this disambiguation in mind, here are the three main meanings.

2. Meaning #1 — Public Budget / Appropriation

In this context, "budget" is the legal authority to spend public funds. Users are government agencies; approver is the legislature (annual appropriations act); auditor is the State Audit Office.

Definition under Thai law

Three critical points:

• "Maximum amount" — a ceiling, not a target. The number authorized is authority to spend, not obligation to spend.
• "Incur obligations" — the law itself includes encumbrance/commitment in the definition. Budget systems must therefore track before the obligation arises.
• "For the purposes ... within the time period" — bound to purpose + timeframe. Changing purpose mid-stream requires a formal budget transfer.

Related definitions in the same section:

Constitutional foundation

The 2017 Thai Constitution, Section 140 establishes that public expenditure may only be made under specified laws on expenditure budget, budgetary procedures, budget transfer, treasury reserves, and state fiscal/financial discipline. Section 141 mandates that the expenditure budget of the realm be enacted as an Act of Parliament; if not enacted in time, the prior year's budget continues provisionally.

This means a public budget is not merely a financial document — it is law, passed by parliament. Spending in excess is illegal.

Components and classification

Thailand's Bureau of the Budget classifies expenditures into 5 main categories:

1. Personnel — salaries, permanent and temporary wages, government employee compensation
2. Operating — compensation, utilities, supplies, public services
3. Investment — equipment, land, construction
4. Subsidy — grants and aid to entities/organizations
5. Other — items not classified above

Beyond category-based classification, the public budget system uses an outcome-oriented structure called Strategic Performance-Based Budgeting (SPBB), tying every baht to: Program → Output → Project → Activity. See 23-Digit Budget Code for the full structure.

Additionally, a "Central Fund" (งบกลาง) sits outside any specific ministry/department, used for shared items: pensions, contingency reserves, civil-servant healthcare. And "non-budget revenue" is defined separately in Section 4 of the Act, distinct from "budget" itself.

Four-stage cycle

1. Formulation — agencies submit requests; Bureau of the Budget consolidates
2. Authorization — Cabinet → House → Senate → enacted as a law
3. Execution — disbursement via GFMIS under the Comptroller General's Department
4. Audit — State Audit Office (SAO/OAG)

Measurement basis — the gap that motivates Meaning #3

Thailand's public sector has two layers on different bases:

• Budget execution (disbursement in GFMIS) — primarily Modified Cash Basis
• Financial Statements (annual reports) — Accrual Basis, per "Public Sector Accounting Standard No. 1 — Presentation of Financial Statements" issued by the Comptroller General's Department

This gap between layers is exactly what Meaning #3 (IPSAS 24) addresses.

3. Meaning #2 — Management Budget

Here, "budget" is an internal planning & control tool. Users are management/finance; approvers are the board/executives. It has no legal status — it can be revised, reforecast, or exceeded under internal approval.

Definitions from professional accounting literature

Both definitions come from Management Accounting — the textbook standard taught in accounting curricula globally. Note the shared phrase: quantitative expression of a plan.

Master Budget components

• Operating Budget → Budgeted Income Statement
  • Sales Budget → Production Budget → Direct Materials / Labor / Overhead
  • Cost of Goods Sold Budget
  • Selling & Administrative Expenses Budget
• Capital Expenditure Budget → long-term asset investment
• Financial Budget → Budgeted Balance Sheet + Cash Flow
  • Cash Budget
  • Budgeted Balance Sheet + Budgeted Cash Flow Statement

Types by preparation method

Type	Description
Static Budget	Set at one activity level; doesn't adjust to actuals
Flexible Budget	Adjusts to actual activity level — gives more accurate variance analysis
Zero-Based Budgeting (ZBB)	Starts from zero each period; every dollar must be re-justified
Activity-Based Budgeting (ABB)	Allocates by activities and cost drivers, not account categories
Incremental Budgeting	Starts from prior year + percentage change

Cycle and legal status

The Management Budget cycle is an internal management cycle: Plan → Execute → Control (Variance Analysis: Actual vs Budget) → Re-forecast. No legislative oversight. Excess spending is handled via internal approval. Measurement is typically Accrual Basis, aligned with TFRS/IFRS reporting.

4. Meaning #3 — Approved Budget per IPSAS 24 (Bridge)

Meaning #3 is the bridge between the first two. Because public sectors have two layers on different bases (budget = cash, FS = accrual), a standard is needed to bring both bases together in a single document.

Origin

IPSAS 24 — Presentation of Budget Information in Financial Statements, issued by IPSASB (International Public Sector Accounting Standards Board) under IFAC, is a public-sector-specific standard for entities preparing accrual-basis financial statements that publicly disclose their approved budget.

In Thailand, Section 68 of the State Fiscal and Financial Discipline Act B.E. 2561 (2018) authorizes the Ministry of Finance to set Public Sector Accounting Standards and Policies. The Comptroller General's Department issues these standards, which are based on the IPSAS framework.

Objective of IPSAS 24

IPSAS 24 ensures that public sector entities discharge their accountability obligations and enhance the transparency of their financial statements by demonstrating compliance with the approved budget(s) for which they are held publicly accountable.

Key terms

Term	Meaning
Approved Budget	Budget approved by a legislative body (e.g., parliament)
Original Budget	Initial approved budget for the period
Final Budget	Original + transfers / amendments / supplementary appropriations approved during the period
Comparable Basis	Presenting actuals on the same accounting / classification / time basis as the approved budget

Disclosure requirements

• Present Original budget and Final budget
• Show Actual amounts on a comparable basis
• Explain material differences between budget and actual
• Disclose budgetary basis and classification basis
• Reconcile actuals on comparable basis to actuals in the financial statements (when bases differ)

That IPSAS 24 explicitly recognizes "budget and FS in the public sector are commonly on different bases" is normative international evidence supporting the central observation of this article: "budget" in government accounting ≠ "budget" in management accounting, even though they share the same word.

5. Semantic Comparison Across Three Meanings

Summary semantics across the three contexts, organized by academic dimension:

Dimension	Public Budget	Management Budget	IPSAS 24 (Bridge)
Core definition	Maximum amount legally authorized to spend	Quantitative expression of a plan	Approved budget for which the entity is publicly accountable
Legal status	Statute (Act of Parliament)	Internal management tool	Disclosure standard in financial statements
Approver	Parliament	Board / executives	Legislative body (parliament / local council)
Measurement basis	Modified Cash (execution) / Accrual (FS)	Accrual	Reconcile budget basis ↔ FS basis
Excess permitted?	No — legal/fiscal-discipline violation	Yes, with internal approval	— (a reporting requirement)
Components	5 expenditure categories + Program/Output/Project/Activity	Operating + Capital + Financial Budget	Original / Final Budget + Actuals on comparable basis
English term	Appropriation, Public Budget	Master / Operating Budget, Plan	Approved Budget
Primary reference	Budgetary Procedures Act 2018 / Constitution §§140-143	CIMA, Horngren, IMA SMA	IPSAS 24 (IPSASB)

6. Disambiguation Drill — What context is this sentence?

The best way to test understanding is to take real-world sentences and map them back to context.

Sentence	Context	Reason
"This year's budget passed parliament at THB 3.6 trillion."	Public	"Passed parliament" = annual appropriations act
"How much marketing budget is left this quarter?"	Management	"Quarter" + "left" + by department = internal tracking
"Can we exceed the budget?"	Ambiguous	Public → requires transfer/supplement / Private → manager approval
"How much of the central fund is used?"	Public	"Central fund" is a public-sector technical term
"Variance against the flexible budget this month"	Management	Flexible budget is a management-accounting concept
"The company is preparing next year's budget"	Management	"Company" + "next year" = annual planning
"We must disclose budget vs actual in the financial statements"	IPSAS 24	"Disclose" + "financial statements" = normative disclosure
"This project's budget is THB 500K"	Ambiguous (often: allocation)	"Budget" alone often means an allocation, not a master budget
"The agency hasn't disbursed on schedule"	Public	"Disbursement" = budget execution in public-sector systems
"How much budget remains in Q3?"	Either	Public → remaining in GFMIS / Private → variance vs budget

7. Common Pitfalls — Words Not to Swap

"Budget" ≠ "Financial Statements"

Budget = forward-looking plan
Financial Statements = backward-looking report — Balance Sheet, Income Statement, Cash Flow Statement

"Budget" alone — 4 meanings depending on context

1. Spending limit — "budget for the house: THB 2M"
2. Budget item — "meeting budget: THB 5K"
3. Financial statements (in casual Thai/English speech: "company's budget" → often means FS)
4. Budget category — "personnel budget", "investment budget"

"Estimate" ≠ "Budget"

Estimate = projected number, no formal approval
Budget = approved plan, with authority

Note: the Budgetary Procedures Act 2018 uses "Revenue Estimate" (revenue is estimated because it isn't fully under government control) but "Expenditure Budget" (expenditure is authorized because it is).

8. Worked Example — One Event, Three Lenses

An agency contracts a vendor for system development at THB 500,000 under program "Internal Digital Transformation" / output "e-Document System".

Time	Event	Public Budget	Accrual FS	IPSAS 24
Month 1	In-principle approval	Reserved — available drops 500K	—	Recorded in budget execution data
Month 3	PO / contract signed	Encumbered	— (memo)	Budget execution: committed
Month 9	Phase 1 delivered	File disbursement 200K	Starts to appear 200K (Dr. Asset / Cr. Payable)	Disclosure begins: actual 200K vs budget 500K
Month 13	Phase 2 delivered	File 300K	Recognized 300K	Total actual 500K = full budget

From months 1–9 (8 months), the Accrual FS view shows "nothing happens" — quarterly P&L isn't affected — but in the Public Budget view, 500K is already committed, and IPSAS 24 requires disclosure of budget execution data that may not match the FS until the year-end reconciliation.

9. Practical Takeaway for Executives

Once you accept that one word holds three meanings, before any "budget" discussion, ask:

• "Do you mean the legal budget (appropriation passed by the legislature/board), or our internal budget plan?"
• "Are we on cash basis or accrual basis?"
• "Is this number original budget, final budget, or revised forecast?"

These questions are short but prevent miscommunication immediately — especially in cross-functional meetings (executives, accountants, auditors, regulators).

11. Three Sentences to Remember

1. "Budget" is a polyseme — one word, three meanings: Appropriation, Management Budget, Approved Budget under IPSAS 24.
2. Adjacent terms but not synonyms: financial statements, balance sheet, estimate, allocation — each has its own scope.
3. Before discussing, clarify which context the other side means — "legal or internal? cash or accrual? original or revised?"

One word can carry three meanings across three contexts — sender and receiver must agree on which one before financial communication can be precise.
