Loading Multi-Year EBA Rate Increases Automatically

Load every agreed increase as an effective-dated rate before the first payroll. The payroll system should select the rate from the work date, preserve earlier rates for back pay, and flag shifts that cross an increase date.

The trick is not simply entering next year’s hourly rate. You need to load the clause that controls when it starts, who receives it, and which allowances, penalties and super contributions move with it.

Start with the wording in the EBA

Grab the approved enterprise agreement and any incorporated schedules. Do not build the rate table from a spreadsheet handed around on site unless you have checked it against the agreement.

Look for four things:

1. The increase amount, such as 3 per cent or 85 cents an hour.
2. The commencement rule.
3. The classifications and employees covered.
4. Any linked allowances, penalties or super contributions.

The commencement wording matters. One agreement might say rates rise on 1 October. Another might say the increase applies from the first full pay period starting on or after 1 October. Those rules produce different pay results.

An employee working from Monday 28 September to Sunday 4 October may receive two rates if the change applies by work date. If the clause uses the first full pay period rule, the old rate may continue for that whole period.

Read the broader guidance in the EBA payroll hub before setting up a new agreement or changing coverage.

Use effective-dated records

Each rate needs its own start date. Where possible, also give it an end date. Never overwrite the current rate with next year’s amount.

Say the current hourly rate is $35.00 and the EBA provides three annual increases of 3 per cent. The following table is an illustrative setup, not a rate applying across the construction industry.

Rate period	Increase	Hourly rate	Payroll status in October 2026
To 30 September 2026	Existing rate	$35.00	Historical
1 October 2026 to 30 September 2027	3%	$36.05	Active
1 October 2027 to 30 September 2028	3%	$37.13	Approved future rate
From 1 October 2028	3%	$38.24	Approved future rate

For this worked example, the active rate is $36.05 an hour as at October 2026. The next scheduled rate is $37.13 from 1 October 2027, and the following rate is $38.24 from 1 October 2028.

Store the source amount before rounding. For example, $36.05 multiplied by 1.03 is $37.1315. The EBA may tell you whether to round each rate, round to a particular decimal place, or calculate from an unrounded base. Follow that wording rather than assuming two decimal places at every step.

Set the correct activation trigger

A future rate should not activate because someone happens to process payroll after the increase date. Activation should follow the clause.

Common triggers include:

• the date each shift or hour was worked
• the pay period start date
• the first full pay period beginning on or after a stated date
• the employee’s classification anniversary
• completion of an apprenticeship stage
• practical completion or another project milestone

Do not use payment date unless the EBA says to. A fortnight paid on 8 October might contain work completed before and after 1 October.

Cross-midnight shifts need a rule too. The agreement may allocate the whole shift to its start date, or require hours to be split at midnight. Test that case before the rate goes live.

Link derived payments to the right base

Once the base rate changes, other amounts may also change. Construction payroll often includes overtime, shiftwork, fares, travel, site allowances, tool allowances and productivity payments.

Some are fixed dollar amounts. Some are percentages of the base rate. Others are calculated using an award rate or a separately defined EBA rate.

If overtime is 150 per cent of the ordinary hourly rate, an increase from $35.00 to $36.05 changes that overtime rate from $52.50 to $54.08, subject to the agreement’s rounding rule. Do not create a separate hard-coded overtime amount if the clause defines it as a multiplier.

The same warning applies to allowances. An allowance does not automatically rise just because the base rate rises. Schedule an increase only where the EBA provides one.

Keep statutory and agreement rules separate

A few legal checkpoints help keep the setup grounded:

• The super guarantee rate is 12 per cent as at October 2026. An EBA may require more, use a broader earnings base, or set a minimum contribution.
• The National Employment Standards maximum for a full-time employee is 38 hours a week, plus reasonable additional hours, as at October 2026. An EBA can arrange ordinary hours, but it cannot exclude the National Employment Standards.
• An approved enterprise agreement generally starts 7 days after Fair Work Commission approval unless a later date is specified, as at October 2026.
• A standard enterprise agreement’s nominal expiry date generally cannot be more than 4 years after approval, as at October 2026. Certain greenfields agreements for major projects can have a nominal term of up to 8 years.

Check whether the EBA has a minimum weekly super contribution rather than relying only on a percentage. The minimum weekly super calculator helps test the agreement amount against the contribution produced by the employee’s earnings.

Also monitor the relevant modern award. An EBA base rate cannot fall below the applicable award base rate for the classification. A scheduled EBA increase does not remove the need to check later award changes.

Assign coverage carefully

Do not apply an EBA merely because an employee has started work at a particular site. Coverage normally depends on the employer, the agreement’s coverage terms, the employee’s duties and classification, and whether the agreement is in operation.

Store at least these fields against the employee or assignment:

• agreement name and version
• classification and level
• employment type
• effective coverage date
• project or site where relevant
• apprentice stage or year
• approved exceptions

If a worker moves classification halfway through a period, calculate each portion under the correct effective-dated record. Keep the old assignment for audit purposes.

Test before future rates activate

Run a preview payroll before each increase date, even when the rates were loaded years earlier. Circumstances can change after setup.

Test at least one employee for each classification and include:

• ordinary hours before and after the increase
• overtime at every applicable multiplier
• weekend and public holiday penalties
• shift allowances
• fixed and percentage-based allowances
• leave taken and leave paid out
• minimum weekly super
• cross-midnight work
• an employee changing classification

Compare the preview with a manual calculation. Have another payroll person approve it. Record who checked the rates, which EBA clause was used, and when the future records were released.

Handle corrections without destroying history

If a future rate was entered incorrectly, amend the future record before it activates. If the incorrect rate has already been used, do not overwrite completed payroll data.

Create the corrected effective-dated rate, identify affected employees and recalculate the relevant work periods. The adjustment should show the original amount, corrected amount and difference. This leaves a clear path from the EBA clause to the employee’s back pay.

That is the real benefit of loading multi-year increases properly. Payroll can apply the right rate when the date arrives, while old pays remain tied to the rates that were used at the time.
