I'm planning to become self-employed as a handyman and looking for
some basic/cheap/free software I can use to keep records and submit
my tax return.

I switched from running a company using Sage Line50 for the last 20
years, to being self employed a year ago, and would strongly recommend
you look at FreeAgent, about £200/year, 30 day free trial available.

I haven't used it to submit a tax return yet, but I've looked at how it
uses the data you've entered through the year to collect the information
it needs to do it, and it looks good enough that I don't think I'll use
an accountant to file my sole trader self assessment forms.

Any recommendations?

It's web based, really makes everything simple, you can create/send
invoices, record mileage and expenses from the phone app, imports
statements that you export from your bank (it can hook direct to you r
bank, but I wouldn't trust the service it uses to have my banking
credentials).

It's by produced by accountants for but people they recognise are not
very interested in accounting, just getting stuff done.

I have a referral code, if you happen to sign up, we both get some discount
