I am working entirely from soft-copy documents. This is both to help me following a change to my vision, and to help prepare for HMRC’s requirements from 2026 for most records to be kept digitally, with one line per transaction, by self-employed taxpayers and landlords.
Here is a reminder of some of the key items of information I shall need for the 2026 tax return, and the dates to gather these together. This is due for submission at the latest 31 January 2027. This year I am asking clients to provide information by 1 September, to guarantee returns are ready for checking and submission on time.
DATES FOR ACTION
1 April – 6 April
Many of my clients use a download of their bank/building society statement as the starting point for their bookkeeping. Please do this early – some credit card providers only allow downloads going back beyond 12 months. Download one single spreadsheet for your whole tax/accounting year, to 31 March or 5 April. Keep two copies – one to work on and one as a backup.
If you have previously worked onto a spreadsheet and are happy with this, that’s fine. If you’d like to move to working from a bank-statement download, ask me if you would like help formatting this.
30 April
Banks and building societies send out or provide online interest statements for the tax year. Please keep these and take a scan or photo to email to me with your other tax information.
If your mortgage statement does not show the mortgage interest separately, please ask the provider for that figure.
31 May
If you have employment or personal pension income, a form P60 will be issued by the end of May. This may be posted or emailed to you, or often this needs to be downloaded from the employer’s online portal. Please keep these and take a scan or photo for me.
5 June
This is the date by which to get your tax-return information to me for the lowest fee for tax-return preparation.
1 September
This is the deadline for getting your tax-return information to me to guarantee the return is ready by the end of December, well in time for checks and submission before the January deadline.
If you don’t have information ready for the end of September, please send it over as soon after that as you can. I shall work on returns in the order I receive the information. But December and January are always extremely busy, and during January, VAT returns and MTD quarterly updates take priority.
Thank you!
TAX-RETURN INFORMATION
New in the 2026 tax return: Winter Fuel Allowance if you received that.
All income:
If you think some income may be exempt from tax, or are unsure whether this needs to be shown on your return, let me know about it so I can check.
*New in the 2026 tax return: Winter Fuel Allowance if you received that.*
Employees:
Form P60 (payment summary). By law, employers must provide these to employees by 31 May. Form P11D if you receive any benefits such as a company car or medical insurance. If you have changed job or left employment, form P45. If you have not received your form(s) P60 by 31 May, please ask for a copy straight away.
*New in the 2026 tax return: If you are a company director there is extra information to add to the tax return, including whether you received dividends, and whether the company is ‘close‘ (as most one-person or ‘small’ companies are*
Self-employed income and expenses:
Totals of all earned income, including cash receipts. Record income and expenses on a cash basis (when actually received/paid), unless you are VAT registered, or we have agreed differently. Include the gross income, please, before any tax or national insurance was taken off.
All expenses related to your work: I have a list of typical expenses, but for each transaction, please consider whether this is for your work and whether 100% for work, or not entirely.
Agents’ commission: I need to know the original gross fee before any commission, and the amount of commission taken. For income taxed overseas, the same applies – the gross figure before deductions is needed for the return.
When travelling away from home, reasonable subsistence expenses can be claimed for meals out or at your hotel (or shopped for if self-catering). Food can be claimed for when travelling without an overnight stay under certain, limited circumstances.
Investment income:
This needs to be shown on your return unless it is from an ISA.
Please order or download a certificate from your bank for every account you have, even if interest received was little or nothing during the year. Banks do not necessarily send these automatically.
Please also keep dividend vouchers.
Child Benefit:
If your household receives child benefit, even if it is not paid to you directly, I need to know about it for your tax return. I shall also need to know various information about the taxable income your partner/spouse receives, even if I don’t prepare their tax return. For families where at least one parent has taxable income of £60,000+, there will be extra tax, and for £80,000+, this extra tax will equal the full child benefit received. This is done by taxing child benefit on the higher earner where restriction applies. Each year you should receive a statement showing the child benefit due for the coming tax year. Please keep this as it forms part of your tax records. If you do not already have a statement please ring 0845 302 1444 and ask for confirmation of the amount for the tax year. Child benefit can continue where a child remains in education up to age 20, but at age 16 you will be asked whether this is the case.
Overseas tax:
If you did work outside the UK which was taxed, please keep both the income and the expenses for each country separate from everything else, as separate accounts have to be drawn up. Include the gross income, please, before any tax or social security was taken off.
Anyone travelling to mainland Europe to work in other EU countries is likely to need a form A1 (previously E101) in order to avoid paying social security overseas as well as in the UK. Please let me know as soon as overseas work is booked even if all details are not finalised, so an application can be made as early as possible. Class 2 NICs will be collected with your income tax rather than billed or debited separately.
If you had one or more form A1 recently, some of your Class 2 may still be collected by the NI office, who will post you an invoice. This needs to be paid separately: please let me know the amount you are paying. Unless we are sure all Class 2 is covered, I add this (around £150) into the tax return and we wait for HMRC to adjust if necessary once the return in submitted.
Pensions:
If you pay into a personal pension, this needs to be included in the tax return.
If you receive pension income, you should be sent a separate P60 for every pension you have, except for the State Pension, for which a letter is sent out each year detailing the amounts to be paid to you in the coming tax year. I need to see this and any forms P60 when I prepare your return. In recent years there have been issues with discrepancies between the state pension amounts received into clients’ bank accounts and the figures HMRC receives from DWP and therefore expects in the return. I am suggesting that any clients who do not have a pension statement for State Pension make a call to the Pensions Service 0800 731 0469 to check what figure DWP are passing to HMRC for their return.
*MOST COMMON MISSING INFORMATION*
These are the items clients often find themselves chasing very close to 31 January – don’t be caught out!
- Forms P60
- Mortgage interest statements. If you are self employed based at home or have a property you rent out, we may claim part or all of the mortgage interest you pay. Please order a certificate from your mortgage provider showing the interest only paid in the year(s) for which we are preparing accounts.
- Gift aid payment details. If you pay tax at 40% or more, these will save you some tax when included in your return. If your tax is low, gift aid payments must still be included. If you have no tax bill based on your income, HMRC will charge you tax on any gift aid payments you made.
- Bank interest
- Payments into personal pensions
And these are things clients sometimes forget to let me know about:
- Student loans need to be shown on the tax return.
- Being director of a company (even if no money was received from that company)
- Items sold recently: work equipment/shares/other investments.
- Gift Aid donations to charity: many people make regular donations by standing order but forget to include these, or don’t realise that they need to appear in the tax return. Any one-off donations for which you ticked a box saying you are a taxpayer will also need to be included. If you pay little or no tax, and make Gift Aid payments, there may be some extra tax for you to pay when your tax return is submitted, unless you let the charity know you do not pay sufficient tax for them to take advantage of the Gift Aid element.
- Please also let me know about any changes in family circumstances.
I recommend checking your ‘NI record’, which affects your entitlement to State Pension, every year or two. You can do this here https://www.gov.uk/check-national-insurance-record
