Common GST Mistakes and How to Avoid Them

Common GST Mistakes and How to Avoid Them

Filing Goods and Services Tax (GST) returns in New Zealand can be straightforward, but some common mistakes may lead to penalties or audit risks. Here’s a guide to the most frequent GST errors businesses make and tips for avoiding them.

Incorrect GST Filing Basis

Problem: Using the wrong GST accounting basis, such as invoice basis instead of payments basis, can lead to discrepancies in your GST returns.

Solution: Check your registration details in myIR to confirm your accounting basis and ensure your records match this method. Consult Inland Revenue or a tax professional if unsure.

Over-Claiming GST on Private Expenses

Problem: Claiming GST on personal expenses or the private portion of business items may lead to overstated deductions.

Solution: Separate business and private expenses. If an item is partly for personal use, claim only the business portion of GST.

Misclassifying Zero-Rated and Exempt Supplies

Problem: Mixing up zero-rated supplies (like exports) with exempt supplies (e.g., financial services) can lead to incorrect GST calculations.

Solution: Understand the difference between zero-rated and exempt supplies. When in doubt, check the Inland Revenue GST guidelines or consult a tax expert.

Errors in Input Tax Claims

Problem: Incorrectly claiming GST on non-claimable expenses, such as entertainment or overseas purchases, can lead to over-claimed GST.

Solution: Only claim GST on eligible business expenses. For partially claimable items, like entertainment, apply the correct percentage (usually 50%).

Ignoring GST Adjustments for Business Assets

Problem: Failing to adjust GST for assets used both privately and for business can lead to inaccurate reporting.

Solution: If an asset is used for both business and personal purposes, apportion the GST accordingly. Update records regularly to reflect any changes in usage.

Missing Filing Deadlines

Problem: Missing the GST filing deadline leads to penalties and interest charges from Inland Revenue.

Solution: Set reminders for each filing period (monthly, two-monthly, or six-monthly). Setting up direct debit or early submission can help avoid missed deadlines.

Failing to Correct Errors in Previous Returns

Problem: Errors in previous GST returns, if uncorrected, may carry over and lead to larger discrepancies or potential audits.

Solution: For minor errors, correct them in the next GST return. For major issues, contact Inland Revenue directly to discuss necessary amendments.
