Tradie Forms: finish the Tasmania gratuitous work certificate before prescribed work starts. These checks help you avoid the mistakes that usually trigger CBOS questions or office rework.
Most gratuitous work certificate mistakes are boring admin errors: wrong site, stale licence details, vague work descriptions, or a missing owner signature. They are easy to fix if you catch them before export.
Use the TAS gratuitous work form as a pre-export checklist.
Mistake 1: Treating the form like informal paperwork
Gratuitous work does not mean informal paperwork. CBOS still expects a complete certifier block, owner details, prescribed work description, insurance declaration, and owner sign-off.
Fix: treat the certificate like any other compliance record and finish it before tools go in.
Mistake 2: Copying owner details from the wrong job
Owners with similar names, rental properties, or multi-site portfolios make it easy to paste the wrong contact block.
Fix: confirm the owner and site while you are standing at the property.
Mistake 3: Writing a work description that is too vague
Lines like "plumbing work" or "gas repair" do not explain the prescribed scope.
Fix: describe the actual work, fixture, appliance, or system involved.
Mistake 4: Guessing on insurance coverage
The insurance section is not a tick-box afterthought. If coverage is unclear, confirm it before export.
Fix: only declare coverage once you know the position for that job.
Mistake 5: Leaving sign-off until later
Owner signatures are often the last thing added, which means the form sits unfinished in the ute.
Fix: complete owner sign-off while the owner is still on site and understands the work.
Mistake 6: Forgetting to keep a lodged copy
CBOS lodgement is not the end of the record. The office still needs a copy when someone asks what was certified.
Fix: export, lodge, and file the PDF in the same job record.
