Self Assessment service

If you’re self-employed, you need to file your Self Assessment for the 2018/19 tax year and pay any tax you owe to HMRC by 31st January 2020. Self Assessments can get a little complicated if you’re unsure of the process, but that’s where we can help.

We can prepare and file your Self Assessment tax return for you. Better yet, if you get in early, you can save yourself some money along with all the hassle that a last-minute January scramble can create.

Missing HMRC’s 31st January 2020 deadline will result in an automatic late filing penalty of £100, plus other charges based on the amount of tax you owe. No-one needs that 30 days into the new year, do they?

Our prices increase as we get closer to the filing deadline, so the sooner you get us on the case, the better. All you need to do is complete your Self Assessment questionnaire through your Crunch account, submit all the necessary supporting documentation, and pay for your service. If you pay by Friday 13th December 2019, we’ll make sure your Self Assessment is filed by the 31st January 2020 deadline.


All our pricing is conducted with the greatest transparency and you will be issued with a quote based on the information you supply. If further information comes to light, we reserve the right to adjust our prices accordingly.

Simple returns
A simple return includes all standard income sources such as bank and building society interest, state benefits, income from employment and dividend income.
Complicated returns

If you have any additional sources of income such as sole trading, renting out a property, foreign income or capital gains etc., your return is complicated and requires additional work from our accountants. An additional £125 +VAT will be charged if you'd like Crunch to prepare your sole trader accounts.

Exceptional returns
If your return is not covered by the above descriptions, it’s likely your Self Assessment tax is exceptionally complicated. We'll need to review your request before agreeing a price with you. Exceptionally complicated returns include transactions such as share disposals, requests for tax relief, or holdover elections required for share disposals. 

Remember that if you're on a Crunch Plus or a Crunch Premium package you can get a Self Assessment filing for at least two directors per subscription year, depending on the package type. Please check your Crunch Account for your entitlement. 

If you'd like Crunch to file your Self Assessment or have any queries on the subject, simply get in contact with your client managers.

For more information on what you need to provide, check out our "Self Assessment service requirements" article.

Overdue returns
Your Self Assessment is overdue when the filing deadline of 31st January has passed. You will incur fines and penalties if you do not file a return when due.

Our prices for an overdue return, regardless of the tax year involved, start at £275 per return. However, we will need to review your situation before agreeing a price with you.
