Section 2 -- Required Inputs and Refusal Catalogue

Required Inputs

Minimum viable -- bank statement or record of gross sales/receipts for the year, TIN (Tax Identification Number), and confirmation of whether 8% flat rate or graduated rates are elected.

Recommended -- all sales invoices/official receipts, purchase records, BIR Form 2307 certificates of withholding, prior year ITR (Form 1701/1701A), BIR registration (Form 2303 / Certificate of Registration).

Ideal -- complete books of accounts, general ledger, trial balance, quarterly ITRs (Form 1701Q), percentage tax returns (Form 2551Q), VAT returns (Form 2550Q) if applicable.

Refusal Catalogue

• R-PH-1 -- Corporation or partnership — This skill covers sole proprietors and individual professionals only. Corporations file Form 1702. Escalate to a CPA.
• R-PH-2 -- VAT-registered taxpayer — VAT-registered taxpayers have additional obligations (Form 2550Q/2550M) and cannot use the 8% flat rate option. Income tax still applies but filing differs.
• R-PH-3 -- Mixed income earner (employment + business) — Mixed income earners can use the 8% option only on business income, while employment income is taxed at graduated rates. Requires careful computation.
• R-PH-4 -- Non-resident alien — Non-resident aliens have different rules (NRA-ETB or NRA-NETB). Out of scope.

Section 6 -- Worked Examples

Example 1 -- 8% Flat Rate

Input: Freelance graphic designer. Gross receipts ₱2,400,000. No employees.

Tax: (₱2,400,000 - ₱250,000) × 8% = ₱172,000. No percentage tax. No documentation of expenses required.

Example 2 -- Graduated with OSD

Input: Same freelancer, ₱2,400,000 gross.

OSD: 40% × ₱2,400,000 = ₱960,000. Net taxable income: ₱2,400,000 - ₱960,000 = ₱1,440,000. Tax: ₱102,500 + (₱1,440,000 - ₱800,000) × 25% = ₱102,500 + ₱160,000 = ₱262,500. Plus 3% percentage tax: ₱2,400,000 × 3% = ₱72,000. Total tax burden: ₱262,500 + ₱72,000 = ₱334,500.

Comparison: 8% flat rate (₱172,000) is significantly better for this taxpayer.

Example 3 -- Graduated with Itemized Deductions

Input: Consultant, gross receipts ₱2,400,000, documented expenses ₱1,800,000.

Net taxable income: ₱2,400,000 - ₱1,800,000 = ₱600,000. Tax: ₱22,500 + (₱600,000 - ₱400,000) × 20% = ₱22,500 + ₱40,000 = ₱62,500. Plus 3% percentage tax: ₱72,000. Total: ₱134,500. Better than 8% due to high expenses.

Section 7 -- Penalties

Penalties (NIRC ss.248–250, 255; RR 21-2018; RA 11976 (EOPT). Corrected by Jonathan I. Ruiz (CPA, Philippines))
