Need to mitigate the costs of your tax? Tax Management NZ (TMNZ) provides the best tax management solutions and is New Zealand's original provisional tax intermediary approved by Inland Revenue. We were established to make it easy for all provisional taxpayers to manage their provisional tax payments and reduce their exposure to use of money interest (UOMI). We help our clients to: ¥ Reduce the interest cost on underpaid tax (usually 3% p.a. below Inland Revenue rates) ¥ Sell tax to get higher interest than IRD rates on tax refunds (usually over 2% p.a. above Inland Revenue rates) ¥ Get finance to pay forthcoming provisional tax payments at much lower rates than traditional channels Ð no pre-approvals required We've been in business since 2003. We have added millions of dollars of value to New Zealand businesses including many of New Zealand's top 200 companies (including all of the largest trading banks) and the major chartered accountancy firms.
