What you need to know
The best tax return software guides you through your Self Assessment in a logical sequence, showing only the fields that apply to your situation. Removing unnecessary steps keeps the process moving and reduces the chance of errors before submission.
Pie is designed around this principle. Our guided flow adapts to your answers, pre populates where possible, and validates your return before it reaches HMRC so most users can move from start to submission in a single session.
For the 2025/26 tax year, filing online also means faster HMRC processing and quicker repayments where applicable. If you are new to Self Assessment, our guidance covers everything you need to get started with confidence.
Software for Self Employed Tax Returns
Self employed workers need software that handles sole trader income, allowable expenses, and National Insurance contributions clearly, without requiring an accounting background. Plain language prompts throughout the process make the difference between guesswork and a confident, accurate filing.
Pie walks you through turnover, business costs, and expense categories in straightforward terms, then calculates your Class 2 and Class 4 NI contributions automatically. You do not need to know HMRC terminology to arrive at the right figure.
With Making Tax Digital for Income Tax expanding to more sole traders in the coming years, understanding how to manage your self employed income records now puts you in a much stronger position ahead of those changes.
Mixed Income Tax Return Software
A mixed income return requires software that can hold PAYE employment income and self employment earnings side by side, accounting for the tax already deducted by your employer before calculating what you still owe.
Getting this balance right is one of the more common challenges for people filing Self Assessment for the first time. Pie lets you enter both income sources separately, then combines them accurately applying the correct tax bands, personal allowance, and any relevant reliefs to give you a clear picture of your position before you file.
If you are unsure how your employment income and side business interact for tax purposes, our guidance explains how each element feeds into your overall Self Assessment return.
Real Time Expense Tracking
Real time feedback is one of the most useful features in tax software. When your estimated liability updates as you enter each expense, you can see immediately whether a cost is making a meaningful difference to what you owe and whether you may have missed something claimable.
Pie displays a live tax estimate throughout the filing process. As you add allowable expenses equipment, travel, professional subscriptions, or home working costs the figure adjusts instantly, giving you a clear view of where things stand.
Understanding which expenses are allowable and how to record them accurately is worth exploring before you file.
Software for Investment and Capital Gains
Investment income, dividends, and capital gains each fall under distinct tax rules, with their own allowances and rates. Good software applies these automatically based on your overall income, so you do not need to know the rules before you start. Pie guides you through each income type in a structured way.
Dividends are rated correctly for your tax band, and capital gains entries are calculated net of your annual exempt amount after you record each disposal. For those with multiple asset types or a mix of gains and losses in the same tax year, keeping each entry clearly separated is essential for an accurate return.
Reliable Tax Calculations and Compliance
Reliable tax software applies current HMRC rules accurately and flags inconsistencies before your return is submitted. Errors even unintentional ones can lead to an enquiry or a penalty, both of which the right platform helps you avoid.
Pie applies up to date rates, allowances, and thresholds for the relevant tax year and runs validation checks throughout the process. If something looks out of place, you are prompted to review it before moving on.
Our platform is updated each April to reflect changes in tax legislation, so when you file for 2025/26 you can do so knowing the calculations reflect the rules as they currently stand.
Simple Software for Employment Only Returns
For a straightforward employment only return, the best software removes everything that does not apply and moves you toward submission efficiently. There is no benefit in navigating sections designed for complex tax situations when yours is simple.
Pie recognises from your answers when a return is uncomplicated and adjusts the journey accordingly. You enter your income, confirm your PAYE details, review the summary, and submit with your figures validated before they reach HMRC.
Clear On Screen Guidance
Contextual guidance at each step is what separates a confident filing experience from an uncertain one. When software explains what a section is asking and why it matters, you are far less likely to leave something blank or enter a figure in the wrong place.
Pie includes plain English explanations throughout. Where HMRC terminology might be unfamiliar, we translate it into language that is easy to follow without oversimplifying the rules behind each question.
Save Progress and Return Later
Most people do not complete their tax return in one uninterrupted session. You may need to locate a document, check a bank statement, or simply step away and your software should accommodate that without any loss of progress. Pie saves your work automatically as you go.
Whether you close your browser, switch devices, or return several days later, your return picks up exactly where you left off with all your data intact. This flexibility is especially useful in the weeks approaching the 31 January HMRC deadline.
Support While You File
Access to support while you are mid way through a return can make a genuine difference, particularly if you encounter a question you are unsure how to answer or a figure that does not look right.
Pie offers chat support so you can get help without leaving your return. Our team can assist with how to use the platform, how to categorise income, or what a specific section is asking for.
Final Summary
Pie is designed to make Self Assessment filing faster, clearer, and more accessible for the 2025/26 tax year. With a guided workflow, real time calculations, and built in compliance checks, users can move from start to submission confidently while staying aligned with current HMRC rules.
