Example result
Tax year 2025/26
Your answer
Yes, you need to register for Self Assessment
Your rental profit of £4,200 is above the £2,500 limit for collecting tax through your tax code, so HMRC needs a tax return from you.
- Employment (PAYE)
- £32,000
- Rental profit
- £4,200
- Untaxed interest
- £600
Reliefs you can use
- Personal Savings Allowance: your £600 of interest is tax-free.
- Property allowance: claim £1,000 instead of expenses if your costs are lower.
Next: register by 5 October 2026, then follow the box-by-box guide.
Sound familiar?
These are the questions people ring HMRC about every single day. EaseMyTax was built to answer them without the hold music.
“Do I even need to do a tax return? I’ve got a job and a bit of rent coming in.”
We work it out from your income, and tell you which rule applies.
“My tax code has changed to K475. What does that mean?”
We explain every letter and number, and why HMRC chose it.
“Why is my private pension being taxed so much since my State Pension started?”
Because the State Pension is paid without tax taken off. We show you where it goes.
“There are hundreds of boxes on this return. Which ones are actually for me?”
Usually only a handful. We list them, and what goes in each.
What EaseMyTax does
Four tools, one idea: take the answers an HMRC adviser gives on the phone and turn them into a guide you can follow at home.
Do I need to file?
Answer a short checklist about your income for the year. We tell you whether you must register for Self Assessment, or whether HMRC can collect the tax through your tax code instead.
Start the checkFind your tax reliefs
Personal Savings Allowance, property allowance, pension tax relief, Marriage Allowance and more, worked out from what you told us, with how to claim each one.
Included with the check
Step-by-step return guide
Only the pages and boxes that apply to you. For each one: what to type, where to find the figure, and the mistakes people usually make. Printable, so it sits next to you while you file.
Open the walkthroughTax code decoder
Type in your tax code, or enter the lines from your P2 coding notice, and we explain every one: State Pension, company car, medical insurance, underpayments and the rest.

How it works
Three steps. You stay in control of your own tax return the whole way through.
- 1
Tell us about your income
Pick a tax year and tick what applies: a job, self-employment, rental income, savings interest, pensions, dividends, Child Benefit. Rough figures are fine to start.
- 2
Get a straight answer
Whether you need to file a Self Assessment or not, which rule decided it, the reliefs you can claim, and the dates that matter for your year.

Follow the guide on GOV.UK
Register with HMRC using our word-for-word walkthrough, then complete the real return with our box-by-box guide open beside you.
We never touch your HMRC account. EaseMyTax does not ask for your Government Gateway login, does not file anything on your behalf, and does not send your details to HMRC. You type your figures into GOV.UK yourself, with our guide telling you exactly where they go.
Built for real life, not for accountants
Only what applies to you
Most of a tax return is irrelevant to most people. We hide the rest so you are never guessing whether a box is for you.
Word for word
Not “register online” but: go here, search for this, click that, and expect your UTR by post in around three weeks.
The why, every time
Every answer comes with the reason behind it in plain English, so you understand your own tax instead of just copying numbers.
Official sources
Each step links to the matching GOV.UK page, so you can check anything we say against HMRC’s own guidance.
Who we are
Two people who spent five years answering HMRC’s phones
Between us we took thousands of calls about tax codes, bills, refunds and returns, 8am to 6pm, Monday to Friday. The questions were the same every day, and by the end of each call the person understood. EaseMyTax is that explanation written down, free, for everyone who could not get through.
