Business Accountants: Get Organised for the 31 March Year-End – Key Dates & Tax Reminders

 

With 31 March fast approaching, now’s the perfect time to prepare for the end of the financial year. Acting early can save you time, reduce stress, and ensure your business is ready to thrive in 2025. If you’d like a checklist to guide you through the process, reach out — we’re here to help.


Provisional Tax Reminder


If you’re a provisional taxpayer — such as a sole trader or contractor earning income without tax deducted at the source — your final payment for the 2024 tax year is due on 7 May 2025 (if we prepare your tax returns).


If your tax returns are not prepared by an accountant, your final payment deadline was 7 February 2025.


❓ Unsure if this applies to you? Contact us for guidance — we’ll clarify your obligations and help you stay compliant.

As a new client of Outside Accounting I can only use one word - outstanding. Very proactive and communicative and they take all the hassle out of tax returns. Best around if you have a rental property and are new to the taxation issues that can come up. A++++

The team at outside are a dedicated bunch. They go above and beyond in every situation and provide so much more than your standard tax accounting. They have developed process maps, management reports, managed our invoicing, payables and pretty much taken care of every part of our business when we have needed it. They are a big part of our business and will continue to be moving forward.

A great team - striking the right balance between professional, knowledgable accountants while being fun and personable to deal with. Always quick to respond. Harri has prepared my end of year statements and GST returns. I'm based in Auckland and have managed to snag a spot at the "co-working desk" in their office a couple of times while I'm down in Wellington.

These guys are not the typical accountants. We engaged with Outside originally for our small business accounting needs, but over the years they have provided invaluable services above and beyond. We have grown as a business and Outside worked alongside us the entire time, supporting us with expert and professional advice throughout our journey. They are an awesome bunch, so easy to get along with, they break everything down into regular speak and no question is too dumb to ask. Their door is always open, everyone is super welcoming and they make a mean coffee.

Congress Rental have been working with Outside Accounting for over 1 year and I can honestly say it's been perfect. I work closely with Harriet and her friendliness and professionalism makes it a pleasure getting our accounting needs sorted. Not having to worry about if our accounting gets done is pressure off our business. Harriet breaks everything down into regular terms and nothing asked is a dumb question making learning alot quicker and easier. Not your typical place for accounting as it's a great environment, friendly and things get done in a very high quality manner. Very refreshing. Highly recommended. Many thanks to Harriet and the team. Liam. Managing Director Congress Rental New Zealand Ltd
