GoForma, particularly Jordan Macey from GoForma, have been fantastic from the moment I have been with them. Consistently taking the time to provide the highest standard of advice. They have even continued with their fantastic service when due to financial difficulties I had to pause payment.
Having dealt with GoForma personally I was extremely happy with the pricing and ultimately speed of the services. Definitely will be using them for the next tax year.
I wholeheartedly recommend GoForma. From initial set up of my company, to helping me with numerous tax related queries, and efficiently and promptly assisting me to meet all my tax reporting deadlines, to finalising the closedown of my Ltd company when I chose to retire, they have been fantastic.

.avif)
A self assessment tax return is the method used by HMRC to collect income tax from those who don’t have it automatically deducted, such as the self-employed individual and sole trader.
You usually need to file a Self Assessment Tax Return if you are self-employed, a company director, earn over £100,000, receive rental or dividend income, have capital gains, or earn untaxed income.
A straightforward Self Assessment Tax Return can take a few days once all documents are provided. More complex returns involving dividends, rental income, capital gains or crypto may take longer.
Yes, you can file directly with HMRC using their online system. However, many people miss allowable expenses or miscalculate tax. An accountant helps ensure accuracy, reduce risk of penalties and confirm your tax position before submission.
You are not legally required to use an accountant. However, if you have multiple income sources, dividends, property income or capital gains, professional support reduces errors and can help optimise your tax position while staying fully compliant.
You’ll need records of income, expenses, dividend vouchers, rental statements, CIS deductions, bank interest and any capital gains. HMRC requires you to keep accurate records, usually for at least five years after the 31 January filing deadline.
Missing the 31 January deadline usually triggers an automatic £100 penalty from HMRC, even if no tax is due. Additional daily penalties, interest and further charges can apply if the delay continues.
You’ll need your UTR number, income records, expenses, and any other tax-relevant documents.
Yes - we have a separate service and page dedicated to crypto capital gains tax returns.
HMRC can typically investigate tax returns going back up to four years. This period can extend to six years in cases of carelessness and up to 20 years if deliberate errors or fraud are suspected.
Yes. You can usually amend your Self Assessment Tax Return within 12 months of the online filing deadline. Corrections must be submitted through HMRC’s system or via your authorised accountant to ensure changes are properly recorded.
The cost of a Self Assessment Tax Return depends on how complex your income is. A straightforward return with one income source will cost less than a return with dividends, rental income, capital gains or crypto transactions. At GoForma, prices start from £195 plus VAT, with clear fixed fees agreed before filing.
At GoForma, we’ve designed a clear, step-by-step process so your Self Assessment Tax Return is prepared accurately, filed on time and fully compliant.

Self Assessment is a system HMRC uses to collect Income Tax. It is a yearly report that tells HMRC about income that has not been taxed at source. You declare your income, claim allowable expenses and calculate what you owe for that tax year.
If you earn money that isn’t taxed through PAYE, HMRC expects you to submit a Self Assessment Tax Return each year. This helps ensure you’re paying the correct amount.
Key points at a glance:
If you’re self-employed, a company director, earn over £100,000, receive rental income, have capital gains, get dividends above the tax-free allowance, or have any other untaxed income, Self Assessment applies to you. Also, if HMRC asks you to submit a return, you must submit regardless of whether you think you owe tax.
If you miss the 31 January deadline, HMRC will automatically issue a £100 fine. If you wait three months, daily penalties begin to add up. At six and twelve months, the costs increase further. Interest is also charged on any overdue amounts.
Self Assessment isn’t identical for everyone. Different taxpayers face different risks. Filing incorrectly can mean penalties, interest, or overpaying tax. Here’s who typically needs to file and how GoForma can help you stay organised.
Our service covers the full process from registration through to filing and post submission support. Every return is reviewed by a qualified UK accountant and filed directly with HMRC.
Here is exactly what is included.
Don’t leave your Self Assessment Tax Return until the last minute. Deadlines are strict, and errors can be expensive. HMRC isn’t lenient about mistakes, they’ll charge penalties, add interest, and sometimes ask awkward questions you’d rather avoid.
At GoForma, our qualified UK accountants handle your Self Assessment from preparation to submission. We review your income, apply the correct tax rules, and calculate exactly what you owe.
Whether you’re self-employed, a company director, a landlord, or earning from dividends or crypto, we give you honest advice and file your return correctly. No last-minute panic. Just reliable, professional support from experienced people.
Take control of your taxes today and file with confidence.
