Step by Step Guide on How to Calculate PAYG Withholding

Are you confused about your PAYG withholding obligations as an Australian business owner? Many employers struggle with calculating the correct amount of tax to withhold from employee payments, which can lead to ATO penalties and unhappy workers. This step-by-step guide on how to calculate PAYG withholding will help you understand your obligations and implement a straightforward system for your business.

Pay As You Go (PAYG) withholding is the system where businesses withhold tax from payments to employees and other workers, then send this money to the Australian Taxation Office (ATO). When you undertake PAYG withholding correctly, you help your workers manage their income tax throughout the financial year, avoiding unexpected tax bills when they lodge their income tax return.

You need to withhold tax from various payment types including:

  • Salary and wages to employees
  • Payments to directors
  • Payments to businesses without an Australian Business Number (ABN)
  • Payments where voluntary agreements are in place

The PAYG withholding system benefits both your business and your workers by:

  • Spreading tax payments throughout the year
  • Reducing the risk of large end-of-year tax bills
  • Helping with cash flow management
  • Ensuring compliance with tax laws

Before you can calculate withholding amounts, you need to set up the right foundations for your business.

Your first step is to register for PAYG withholding with the ATO. You can do this:

  • When you register your business
  • By adding it to your existing business registration
  • Through your tax agent

Ask new workers to complete a Tax File Number declaration form. This provides essential information for calculating withholding amounts, including:

  • Whether they claim the tax-free threshold
  • If they have education debts
  • Their residency status for tax purposes

Calculating the correct withholding amount is straightforward when you follow these steps.

The ATO provides tax tables that tell you how much tax to withhold based on:

  • Your pay frequency (weekly, fortnightly, monthly)
  • The payment amount
  • Information from Tax File Number declarations

For standard salary and wage payments:

  1. Determine the employee’s gross payment for the period
  2. Find the relevant column in the tax table
  3. Find the row that matches their income amount
  4. The amount shown is what you need to withhold

For an employee earning $1,500 fortnightly who claims the tax-free threshold:

  1. Look up the fortnightly tax table
  2. Find the income range that includes $1,500
  3. Read across to the column for employees claiming the tax-free threshold
  4. Withhold the amount shown

Different rules apply when calculating withholding for:

  • Bonuses and commissions
  • Termination payments
  • Contractors under voluntary agreements

After calculating how much tax to withhold, you need to report and pay these amounts to the ATO.

Report withheld amounts in the PAYG tax withheld section of your Business Activity Statement (BAS). Complete all required fields including:

  • W1: Total salary, wages and other payments
  • W2: Amounts withheld from payments
  • W4: Amounts withheld where no ABN is quoted

Many businesses now use Single Touch Payroll (STP) to report employee payments and PAYG withholding in real time. With STP:

  • Payment information is sent to the ATO each payday
  • End-of-year payment summaries are replaced by income statements
  • Employees access their tax information through myGov

PAYG withholding applies to tax you withhold from payments to others. PAYG instalments relate to tax you pay on your own business and investment income.

Failing to meet your PAYG withholding obligations can result in penalties. It’s important to calculate and withhold the right amount of tax.

Meeting your PAYG withholding obligations doesn’t need to be complicated. By following this guide and keeping up with your responsibilities, you can ensure your business remains compliant with ATO requirements.

Remember to:

  • Register properly before making your first payment
  • Use the correct tax tables for calculations
  • Report and pay withheld amounts on time
  • Provide payment summaries or finalise STP data by the end of the financial year
