In our recent discussion with Senior Lighthouse Accountant Vinay Reddy and Lighthouse Managing Director Matt Harris, we explored what can happen after 10 years without filing taxes. While it might feel easier to ignore the problem, tax obligations don’t disappear - and the longer they’re left unresolved, the bigger the consequences can become.
Why Tax Problems Snowball
One of the most common patterns accountants see is how small tax issues gradually escalate into much larger problems. What might start as a missed return or a deduction error can compound over time if it isn’t addressed.
When someone spends 10 years without filing taxes, the tax itself isn’t the only issue. Inland Revenue can apply penalties and interest to unpaid amounts, and those charges accumulate the longer the situation remains unresolved.
The reality is simple: unpaid tax doesn’t disappear. Instead, the financial pressure increases over time, often creating more stress and making the problem harder and more expensive to fix.
The Real Cost
When accountants begin reviewing situations where someone has gone 10 years without filing taxes, they often discover the issue is larger than expected.
It’s rarely just income tax. Other obligations may also apply, including:
-
GST obligations
-
Student loan repayments
-
ACC levies
All of these can compound the overall amount owed. What initially seems like a manageable tax issue can quickly become a much larger financial challenge once all obligations are accounted for.
Interest and penalties also add to the total. Inland Revenue may charge “use of money interest”, which has recently been around 8-9%, along with late payment penalties that increase over time.
This combination is what causes tax debts to snowball.
How IRD Can Respond to Long-Standing Tax Issues
Another major impact of unresolved tax issues is the effect on day-to-day financial life.
Outstanding IRD debt can raise red flags with banks and lenders. If the total tax liability is unclear or unresolved, borrowing becomes more difficult and opportunities can be delayed or lost.
In more serious cases, Inland Revenue may take stronger action. This can include:
For business owners, this can create major disruption – particularly if the business suddenly needs to repay years of tax liabilities all at once.
Fixing the Problem: Where to Start
While the situation can sound intimidating, there are established processes for resolving overdue tax issues.
The first step is getting financial records back in order and understanding what went wrong. Often, Vinay notes that the issue begins when business owners try to handle everything themselves despite not being experts in accounting.
Once records are organised, accountants can approach Inland Revenue with a voluntary disclosure explaining the situation. This typically includes:
Arrangements often involve an upfront payment combined with manageable monthly repayments – frequently structured over a period of up to three years. In some situations, IRD may reduce or remit certain penalties and interest depending on the circumstances.
Building Better Tax Systems Going Forward
For business owners, a few simple systems can dramatically reduce the risk of tax issues.
One of the most common mistakes is mixing personal and business spending in the same account. Separating accounts makes it significantly easier to track transactions and file tax returns correctly.
Another practical approach is setting aside a portion of revenue for tax throughout the year. Matt suggests reserving around 25-30% of income (excluding GST) so the funds are available when tax payments fall due.
There are also tools such as tax pooling accounts that allow businesses to hold tax funds in advance and reduce interest and penalty exposure if a payment is needed later.
