Ultimate tax-year-end checklist for investors

Mark Churchill 30 March 2016

There are countless ways to seek a good return on your investment. But one of the most reliable ways to boost what you get back is also one of the simplest. It has nothing to do with the funds and shares you choose, or the time you buy or sell. It is simply to minimise the tax you have to pay.

With the end of the 2015/16 tax year approaching, this checklist is to help you make sure you've made the most of the opportunity to save tax.

You need to take action by midnight on Tuesday 5 April to get the full advantage of all your tax reliefs and exemptions. If you don’t use them within this tax year, they're gone – forever.

You don't even have to have money available to invest right now. Yes, some of these options involve using your allowances if you can afford to. But other tax-saving measures simply involve moving money around – these might be the most overlooked ones.

The checklist

A quick note before we start: this article is neither tax advice nor a personal recommendation to invest. Use tax shelters like ISAs or pensions only if they meet your wider financial planning aims. If in doubt, always speak to an adviser.

You have a number of different tax-saving allowances each tax year so this checklist is in three parts:

ISAs – tax shelter with an annual allowance that renews each tax year

Tax-saving using ISAs…

ISAs are the perennial tax-saving favourite. You don’t need to mention ISAs in your tax returns, nor declare any income or growth from them. A couple can have one each (plus Junior ISAs for any children), and you get a new tax-free investment allowance every year. But your allowance doesn't roll over – it's use-it-or-lose-it. So:

  • If you can afford to, use your full annual ISA allowance of £15,240 before 5 April. You can’t carry any unused allowance into the next tax year.

    For stocks and shares ISAs, this does not mean you have to make all your investment decisions on the spot. You can fund your account now with cash and decide on make your investments later, as long as you've paid in the amount to your ISA account by midnight on Tuesday 5 to secure your 2015/16 allowance.
  • Use the “Bed & ISA” trick to shelter existing investments from future tax

    If you hold shares outside an ISA or SIPP, income and capital gains on these investments are subject to tax. “Bed & ISA” (derived from “bed-and-breakfast”) involves selling existing investments then immediately buying them back within a Stocks and Shares ISA account. Some ISA providers carry out this process for you. There may be dealing charges to pay, so weigh this against the potential tax savings to decide whether it's worth it.

    Even if you have no new money to invest this tax year still presents an opportunity to use your ISA allowance and potentially save tax in future. It can also help you crystallise a gain in this tax year to make use of any unused Capital Gains Tax allowance (see below).

Tax-saving using pensions…

If you have a SIPP or personal pension, these provide investors with further tax-saving opportunities.

  • If you can afford to, make full use of your annual allowance, which lets you contribute up to £40,000 per year into a pension and obtain tax relief on your contributions.

    Using this full allowance would give your pension an automatic £10,000 boost in the form of basic rate income tax relief. If you are a higher- or additional-rate taxpayer, you will be able to claim further tax relief through your tax return.
  • Carry forward any unused allowance from the previous three tax years.

    If you can afford to contribute more than £40,000 this year, and you haven't used your full allowance in the past three tax years (£40,000 in 2014/15 and £50,000 in the previous two tax years), the “carry forward” rule allows you to roll up this unused allowance and potentially contribute up to £180,000 this tax year. To qualify, you must have had a pension for each of those years and have earned at least the amount you are contributing.
  • Use the “Bed & SIPP” method to shelter existing investments within your pension wrapper – this works in the same way as “Bed & ISA”, above.

Within the current tax system you can also use pension contributions to mitigate the effect of other thresholds. For example:

  • If you earn over £100,000, make a pension contribution to reduce your taxable income to below £100,000 and get an effective tax relief of 60% on some, or all, of your contribution. This works because of how your Personal Allowance is affected when your income exceeds this level.
  • Similarly if you earn over £50,000, you can avoid the Child Benefit tax charge by making a pension contribution to reduce your taxable income below the £50,000 threshold.

Other tax-saving opportunities…

If you might incur a capital gain:

  • Make the most of the £11,100 annual Capital Gains Tax (CGT) exemption – this might mean selling investments now to incur a capital gain within this tax year where possible, then buying them back after 6 April. Or if you are married you can immediately buy back shares sold by your spouse to realise a gain, but still keep the shares within the family.
  • Making a pension contribution could reduce your CGT liability from 28% to 18%, since the rate you pay is determined on your taxable income level.

If you're planning to give an inheritance:

  • Make the most of your £3,000 annual Inheritance Tax exemption by making gifts up to this total before the tax year ends.

Act now – don't pay later

If any of these actions are open to you, taking action before 5 April could save your future self thousands in tax, give your pension a timely boost, or line up a windfall for your next tax return.
