Time is running out to submit your 2018 tax return; by 31st January you must complete and submit your return, plus pay any tax due. With a little over two weeks to go, follow our quick tips for a speedy submission and avoid an unnecessary £100 penalty.


Don’t leave completing your tax return until the final day. You’ll need time to gather paperwork such as receipts, statements and invoices to prevent errors being made and inaccuracies being recorded. Plus, as 31st January is also the payment deadline, you don’t want the shock of a hefty bill at 11.59pm!

Create a HMRC Online Account.

As you’ve now missed the deadline for filing a paper return (31st October 2017), you have no option than to submit your return online via HMRC. However, you will need an online account which can take up to a week to process. Once you register and receive your user ID and password, you will be able to use the same details next year (just don’t leave it too late!).

Use an Accountant.

Ok, so with just over two weeks left, you may not have sufficient time to source an affordable self-assessment accountant. However, to maximise possible tax-breaks and to prevent a stressful start to your 2019, hiring an accountant will definitely pay off in the long run.

Use the Simplified Living Expenses Calculator.

If you’re a sole-trader or in a partnership, you can calculate your business expenses for vehicles, working from home and living on your business premises with HMRC’s simplified expenses tool. Alternatively, you can calculate your expenses by working out the actual costs. To see which option best suits your business, try the simplified expenses checker.

Beware the Wining & Dining.

Generally, entertaining, food and drink expenses cannot be claimed as a legitimate expense. Neither can clothing which is not essential for your work, such as a new suit. Check what you can and can’t claim for.

Try Not to Call HMRC During Peak Times.

Findings from a 2016 report by tax advisors, PfP, revealed that customers were waiting in excess of 35 minutes to speak to someone at HMRC, particularly frustrating if you need advice and can only call at busy peak times. However, there are a multitude of online tutorials and help-sheets available on the Revenue’s website, so hopefully, anything puzzling you should be resolved online.
However, occasionally only a real human can help. Call the helpline on 0300 200 3310, 8am – 8pm, Monday – Friday, 8am – 4pm on Saturday, and 9am – 5pm on Sunday.

Don’t Repeat your Mistakes!

Prevent stress next year by keeping a spreadsheet of your business income and expenditure; and keeping all receipts, invoices and associated paperwork in one place. It is also advisable to to use a separate savings account to allocate potential monies owed to the tax-man, even if it’s not for the full amount, you’ll have something to contribute towards the bill.
