Managing provisional tax obligations in an uncertain economy

With ongoing economic uncertainty, many businesses are finding it difficult to forecast their taxable income with confidence. Tax pooling can provide an important safety net in this environment by giving businesses flexibility and control over their provisional tax.

By depositing into a tax pool, taxpayers can secure tax at the correct due dates, while retaining the option to sell any excess if profits fall short. Conversely, taxpayers who find that they’ve underpaid at filing time can purchase tax at historic dates to eliminate Inland Revenue use of money interest and late payment penalties. This flexibility helps businesses maintain compliance and financial efficiency, particularly when operating conditions are volatile.

Another way to make the most of your tax pooling funds is through our Tax Drawdown service. This allows you to temporarily “borrow” from your existing tax deposits and repay them later—without losing the effective tax dates you’ve already secured. In essence, it works much like an overdraft, giving you access to your tax pooling deposits whenever you need them.

You’ll pay the same interest rate as our standard finance arrangements, calculated only from the date you receive the funds until repayment. And just like all our tax purchasing and financing services, there are no account, service, or line fees—keeping things simple and cost-effective.

Now is the perfect time to talk with your clients about how tax pooling can provide peace of mind and financial flexibility. If you’d like to explore how this could work for specific situations, get in touch with our team at taxpooling@pwc.com.

Using tax pooling for group structures

For groups of companies, managing provisional tax can be challenging when entities have varying cash positions and profit levels. Tax pooling allows groups to optimise their overall tax strategy by effectively “sharing” payments across the pool.

A subsidiary with surplus funds in the pool can transfer their excess payments to another group member facing shortfalls at the same effective dates. This approach reduces unnecessary borrowing and ensures group-wide compliance at the lowest cost. As more groups look for efficient cashflow solutions, tax pooling continues to be a highly practical tool.

Every group has unique cashflow and tax challenges. Reach out to us to discuss how tax pooling can help optimise your group’s provisional tax strategy and reduce unnecessary costs.
